Jane bought a poster that had a length of 2 1/3 feet and a width of 3/4 feet. What is the perimeter of her poster?
Answer: 1 1/6
Step-by-step explanation: We are given the length and width of the poster board. The perimeter of an object is the sum of all four sides.
If it helps, picture a rectangle. The length, or the long side, is 2 1/3 feet long. Since both of the rectangle's long sides would be identical, we can assume both sides are 2 1/3 feet long.
This also applies to the short side, or the width. Both ends of the poster board would be 3/4 feet long.
To find the perimeter, you need to add all four sides together. I assume this is the tricky part for you, as you are not sure how to add fractions yet.
First, let's add the two long sides together. 2 1/3 + 2 1/3 would equal 4 2/3. How did I get this? Well, 2 + 2 = 4 (you add the number outside of the fraction first). To add fractions, you look to see if the bottom of the fraction, or the denominator, is the same. As 1/3 and 1/3 have the same denominator, you can leave the 3 alone and only add the top, giving us 2/3.
Duplicate this process with the width. 3/4 + 3/4 would give us 6/4. How do we reduce this? We turn it into what is called a mixed number. This means that there will be a big number on the outside, then a fraction attached to it. How do we turn this improper fraction, or a fraction where the top is greater than the bottom, into a mixed number?
A fraction can also be interpreted as a division problem. You can look at 6/4 as 6 ÷ 4. Four goes into 6 one time, with 2 left over (6 - 4 = 2). We take how many times four goes into 6 (once) and use that as our big number. All we have to do now is take our leftover number (2) and turn it into a fraction. How? We use 4 as our bottom, or denominator, because it is left over from how many times 4 goes into 6. In conclusion, our mixed number is 1 2/4. Reduced, this is 1 1/2, because 2/4 cut in half is 1/2.
So now we have two numbers. 4 2/3 and 1 1/2. How do we add these together if their denominators are different? 2/3 and 1/2 are not compatible by themselves. Well, we need to find a number that both 3 and 2 go into. This number would be 6. But we can't just turn 2/3 into 2/6, we need to multiply the bottom by a number that would make it six, and multiply the top by the same number. 2 • 3 = 6 (from 2/3) so we multiply the top by 2 also. This gets us 4/6. Don't forget the big 4 on the outside to get us 4 4/6!
We do the same to the other mixed number, 1 1/2. Half of 6 is 3, so we can turn 1/2 into 3/6, then we make sure our big 1 is on the outside. Now we can add 1 3/6 to 4 4/6!
First, add 1 and 4 by itself to get us 5. Then, you can add the fractions 3/6 and 4/6 (don't add the bottom, just the top!) to get 7/6. To reduce this, we divide 7 by 6 to get us 1 1/6!

Vertical angles in diagram:
m∠ABD and m∠CBE
m∠ABC and m∠DBE
No complementary angles
x = 20
Step-by-step explanation:
Supplementary angles: two angles whose measures add up to 180°
Complementary angles: two angles whose measures add up to 90°
Vertical angles: a pair of opposite angles formed by intersecting lines. Vertical angles are congruent.
Supplementary angles in diagram:
m∠ABD and m∠ABC
m∠ABD and m∠DBE
m∠DBE and m∠CBE
m∠ABC and m∠CBE
Vertical angles in diagram:
m∠ABD and m∠CBE
m∠ABC and m∠DBE
As m∠ABD and m∠CBE are vertical angles, this means they are congruent:
⇒ m∠ABD = m∠CBE
⇒ 5x - 60 = x + 20
⇒ 4x = 80
⇒ x = 20
Therefore,
m∠ABD = m∠CBE = 40°
m∠ABC = m∠DBE = 140°
There are no complementary angles in the diagram, as there are no two angles whose sum is 90°

Step-by-step explanation:
area is measured in square inches, not just inches.
The area of a circle is 64π in². What is the circumference, in inches? Express your answer in terms of \piπ.
Answer:
8
Step-by-step explanation:
The area of a circle is [tex]\pi[/tex]r²
So we can divide 64[tex]\pi[/tex] by [tex]\pi[/tex] and have 64.
Now take the square root of 64 and its 8
Answer:
the is 16 pie
Step-by-step explanation:
To find the circumference, we would use the formula:
\color{green}{C}=
C=
\,\,2\pi\color{red}{r}
2πr
Circumference of a Circle formula
But we don't know the radius yet. We do know the area, so we can use the area formula to find the radius:
\color{purple}{A}=
A=
\,\,\pi \color{red}{r}^{2}
πr
2
Area of a Circle formula
\color{purple}{64\pi}=
64π=
\,\,\pi \cdot \color{red}{r}^{2}
π⋅r
2
Substitute given circumference into formula
\frac{\color{purple}{64\cdot \pi}}{ \pi}=
π
64⋅π
=
\,\,\frac{\pi \cdot \color{red}{r}^{2}}{\pi}
π
π⋅r
2
Since \piπ is on both sides, divide both sides by \piπ
64=
64=
\,\,\color{red}{r}^{2}
r
2
Cancel out the \piπs from the top and bottom of each fraction.
\color{red}{r}=
r=
\,\,8
8
Squared means something times itself. What times itself equals 64?
\text{The \color{red}{radius} of the circle is \color{red}{8} feet.}
The radius of the circle is 8 feet.
\text{Now use the radius to find the circumference:}
Now use the radius to find the circumference:
\color{green}{C}=
C=
\,\,2\pi\color{red}{r}
2πr
Circumference of a Circle formula
\color{green}{C}=
C=
\,\,2 \cdot \pi \cdot\color{red}{8}
2⋅π⋅8
Substitute radius into formula
\color{green}{C}=
C=
\,\,2 \cdot\color{red}{8}\cdot \pi
2⋅8⋅π
Commutative property of multiplication
\color{green}{C}=
C=
\,\,16\pi
16π
Final answer in terms of \piπ
\text{The \color{green}{circumference} of the circle is 16\(\pi\) ft.}
The circumference of the circle is 16π ft.
Part A -
Write an inequality that represents the possible depth, d, of the teacher's second dive.
Part B-
1. o-------->
2. (filled circle)------>
3. <--------o
4. <---------(filled circle)
Answer:
Part A: x > -60
Part B: 3. <--------o
Step-by-step explanation:
If the researchers explored a deeper depth than -60, that means the depth of the second dive must be more deeper than -60, not equal to it. so x > -60, and deeper depth means more larger negatives, and open circle stands for greater than/less than, so 3. would be the appropriate answer. hope this helps

So I didn’t get a proper answer my last question and I need this done nowwwwwww it’s pre-algebra!
Answer:
1. Anything to do with the same slope but different a B (Ex. y=1/3x+1 and y=1/3x-8)
2. No solutions
Step-by-step explanation:
1. Because the two lines are parallel, when no intersection between two lines happens, there will need to be a change in the B but the same slope. Remember the formula for an equation is y=mx+b. The m stands for the slope. With parallel lines, slopes are the same. If lines were to never intersect, you would have to change the b to a different number so that both lines could keep going at the same time, but never intersect.
2. Remember, solutions only happen when the two lines intersect. Infinite solutions happen when the lines are the same. One solution happens when two lines only have one point where they intersect. No solutions happen when the two lines don't intersect at all. Based off the graph given, there are no intersections so, there will be no solutions.
Mr. Newman will use all of the soap flakes from the boxes to fill bags. He will put of a pound of soap flakes in each bag.
How many -pound bags of soap flakes can Mr. Newman fill? (based on the image)
Answer:
Step-by-step explanation:
All of the dashes on the number line represent a quarter of a pound of soap flakes or 1/4 or 0.25.
Multiply the number of x's on each dash by the number that dash represents.
1 x over 0.25 dash
1 x 0.25 = 0.25
4 x's over 0.5 dash
4 x 0.5 = 2
2 x's over 0.75 dash
2 x 0.75
and so on.

Four identical cubes are joined to make a new shape.
| Answer the questions below to find the new shape’s surface area. |
v v
1a. There are |___| squares on the surface of the figure.
(10, 16, 18, 21)
1b. Each square has an area of |___| in².
(6, 12, 24, 36)
1c. So, the surface area of the figure is |___| in².
(54, 324, 576, 648)
Answer 1a 18 1b 36 1c 648
1a : if you look at the shape you will see its made of squares. I counted the squares, its 18.
1b : one side is 6 in. since its a square all sides are equal. so multiply 6 by 6 to get 36.
1c : this one is easy. We take the number of squares across the surface (18) by the area of each square (36) it is 648.
Also sorry I didn't make this clearer earlier.

Show your work.
WILL MARK BRAINLEST
Answer:
44
Step-by-step explanation:
0.2(x – 4.5) + 1.7 = 9.6
0.2x - 0.9 + 1.7 = 9.6
0.2x + 1.7 = 10.5
0.2x = 8.8
x = 44
Have a great day!
PLEASE MARK BRAINLIEST!
Answer:
44
Step-by-step explanation:
1. Distribute. 0.2 times x = 0.2x. 0.2 times -4.5 = -0.9.
2. Simplify. 0.2x-0.9+1.7 = 9.6
-0.9+1.7 = 0.8 --> 0.2x+0.8 = 9.6
3. Solve for x:
- subtract 0.8 from both sides: 0.2x = 8.8
- divide both sides by 0.2: x = 44

What is 1 2/3 - (- 5 2/3)?
Answer:
7.3333333
Step-by-step explanation:
1 2/3 - (- 5 2/3) = 22/3 = 7 1/3= 7.3333333
detailed:
Conversion a mixed number 1 2/3
to a improper fraction: 1 2/3 = 1 2/3 = 1 · 3 + 2/3 = 3 + 2/3 = 5/3
To find a new numerator:
a) Multiply the whole number 1 by the denominator 3. Whole number 1 equally 1 * 3/3 = 3/3
b) Add the answer from previous step 3 to the numerator 2. New numerator is 3 + 2 = 5
c) Write a previous answer (new numerator 5) over the denominator 3.
One and two thirds is five thirds
Conversion a mixed number -5 2/3
to a improper fraction: -5 2/3 = -5 2/3 = -5 · 3 + (-2)/3 = -15 + (-2)/3 = -17/3
To find a new numerator:
a) Multiply the whole number -5 by the denominator 3. Whole number -5 equally -5 * 3/3 = -15/3
b) Add the answer from previous step -15 to the numerator 2. New numerator is -15 + 2 = -13
c) Write a previous answer (new numerator -13) over the denominator 3.
Minus five and two thirds is minus thirteen thirds
Subtract: 5/3 - (-17/3) = 5 - (-17)/3 = 22/3
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(3, 3) = 3. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 3 × 3 = 9. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - five thirds minus minus seventeen thirds = twenty-two thirds.
