Answer:
23
Step-by-step explanation:
First, substitute 3 in for n in the equation.
5 + 2(3)^2
Using PEMDAS, we can now solve the equation.
3^2 = 9
9 x 2 = 18
5 + 18 = 23

Find the average of this set of numbers.
1, 1, 1, 2, 60
A) 5
B) 13
C) 30
D) none of the above
Answer:
B) 13
Step-by-step explanation:
In order to find the average just add all the numbers
1+1+1+2+60 = 65
Divide by the amount of numbers there are in a set (In this case, there are 5)
65÷5 = 13

4 (x + 7) = 38
x=
Answer:
x = 2.5
Step-by-step explanation:
Hello!
Let's solve the equation together :)
Solve:
4(x + 7) = 38 => Over here, we want to multiply x and 7 by 4, or distribute 4 to both numbers inside the parenthesis.4(x) + 4(7) = 38 =>See how I split the multiplication apart? That's called the Distributive Property4x + 28 = 38 => Simplify. Now subtract 28 from both sides4x = 10 =>Now that we multiply x by 4, we divide both sides to isolate x x = 10/4 => Simplifyx = 2.5Your answer is x = 2.5
Check:
Plug in 2.5 into our equation
4(x + 7) = 384(2.5 +7) = 384(2.5) + 4(7) = 3810 + 28 = 3838 = 38Both sides match so our answer is correct.
The table shows the relationship between the number of drops of food color added to different number of cups of cake frosting:
Cups of
Frosting Drops of
Food Color
2 6
3 9
4 12
Which point below shows an equivalent ratio in this situation?
I'd say that they are all equivalent because when you divided all of them it equals each other.
2:6 = 1/3
3:9 = 1/3
4:12 = 1/3
What are the next Patterns of 7, 77, 11…..
pattern 1 - 7, 77, 11,8, 88,11
Step-by-step explanation:
7×11=77

:Please find the perimeter and also show your work
Answer:
Perimeter= 7.71 ft
Step-by-step explanation: Perimeter= radius(π +2)
The diameter of the circle is 3ft
therefore, radius is 1/2 of diameter (i.e 3/2) =1.5 ft
π=3.14
Therefore, Perimeter= 1.5(3.14 + 2)
Perimeter=7.71 ft

What numbers would be in the in the 4 sections of a 2 x 2 array that shows the problem 18 x 17?
100, 80, 7, 56
100, 80, 70, 56
100, 80, 70, 15
10, 80, 70, 56
In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.
The number in the 4 sections are 100, 80, 70, and 56.
A 2 x 2 array that shows the problem 18 x 17.
2 x 2 array has four blockers or magic quadrants, the matrix diagram is a simple square divided into four equal quadrants.
18 = 10 +8
17 = 10 +7
18 x 17 = 306
In the 2 x 2 array : 100+80+70+56 = 18 x 17 = 306
Therefore, In the 2 x 2 array, the sum of all squares is 18 x 17 = 306.

Monica deposits $
100 into a savings account that pays a simple interest rate of
3.2%. Paul deposits $
200 into a savings account that pays a simple interest rate of
1.9%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your response.
ur not dum
Answer:
Paul
Step-by-step explanation:
Paul earn more than monica. Though he is getting less interest but because of his higher initial amount he is getting more return.
Computing the return of both
Monica return is 100*3.4%= $3.4 in a year
Paul return is 200*%2.2= $4.4 in a year.

Answer:
The first answer is 3) 9(3r-4) and 27r-36
The second answer is 2) Y squared - 36/6
The third answer is 1) 300
Step-by-step explanation:
First answer :
Equivalent expressions are expressions that work the same even though they look different.
9(3r-4) is equal to 27r-36.
9 x 3r = 27r
9 x 4 = 36
27r-36
Second answer :
"The square of y decreased by quotient of 36 and 6" Explains the answer which is Y squared - 36/6
Third answer :
The formula you want to follow is: 2(LW+WH+HL)
2(LW+WH+HL) = 2(12x9+9x2+2x12)
2(12x9+9x2+2x12) = 300
√245 multiplied by √5 = 35, can someone please explain?
Answer:
7√5
Step-by-step explanation:
Begin calculating the factors of 245, starting with 1.
245 ÷ 1 = 245, Remainder = 0
245 ÷ 5 = 49, Remainder = 0
245 ÷ 7 = 35, Remainder = 0
Answer:
The square root of 245 mulitiplied by the square root of 5 you get 35 i.e√245 * √5 = 35

What is the image of ( -9, 0) after a reflection over the X-axis?
Answer:
(-9,0) It would stay the same.
Step-by-step explanation:
Reflection over the X-axis means you keep the 'x' point the same and multiply the 'y' point by -1 (change the sign).
-9 stays the same
[tex]0 * -1 = 0[/tex]
(-9,0)
write an expression for the amount of sugar Farid needs to make 1/2 of a batch of muffins.
Answer:
[tex]\dfrac{3}{4} \ * \ \dfrac{1}{2}[/tex]
Explanation:
Full batch requires [tex]\sf\frac{3}{4}[/tex] cups of sugar.
she is making half the batch so we shall half it.
[tex]\sf\frac{3}{4}[/tex] ÷ 2 → [tex]\sf\frac{3}{8}[/tex] → 0.375note: we can write x ÷ 2, as [tex]* \ \sf\dfrac{x}{2}[/tex]
She is making half batch only, So she will require the half amount of sugar which means we need to multiply 1/2 and 3/4
[tex] \frac{1}{2} \div \frac{3}{4} [/tex]
[tex] \frac{1×3}{2×4} [/tex]
[tex] \frac{3}{8} [/tex]
She will require 0.375 cup of sugar for making 1/2 batch...~

I just need help with finding the yellow (shaded) region. I also need a good explanation because I am SO LOST!
Answer:
The area of the shaded region is 6.88 cm ² (3.44+3.44)
Step-by-step explanation:
Area of the shaded part = Area of the square - Area of the two semi circles + overlapped yellow area
Area of the square = 4² = 16
r = 4/2 = r=2cm
Area of semicircle = πr²/2
Area of the semicircle = π(2) ²/2
Area of one semicircle = 6.28 cm²
Area of two semi-circles = 2 * 6.28 cm²
Area of two semi-circles = 12.56 cm²
Area of the shaded region = Area of a square - Area of two semicircles (plus overlapped area)
Area of the shaded region (minus overlapped area) = 16 cm² - 12.56 cm²
Area of the shaded region (minus overlapped area) = 3.44
Now we need to add the overlapping area of the 2 semicircles
Area overlapped yellow = 1
The other yellow area =2
White parts= S
The area of 2 semicircles with side length 2 (half of 4) is the same.
The area of the big quarter circle is π*2r*2r/4 = π*r², because its radius is twice as big as the small circles.
S = area of each white as the area of the semicircles is:
π*r²/2 = I + S
So, the area of 1 = π*r²/2 - S. The area of the big quarter circle is:
π*r² = 1 + 2+ S + S
Subtract the area of a semicircle circle, and we have
π*r² - π*r²/2 = 1 + 2 + S + S - 1 - S
π*r²/2 = 2 + S
so 2 = π*r²/2 - S.
That means that the area of 1 and 2 are the same
What is the image of the point (8,5) after a rotation of 180 counterclockwise about the origin?
Answer:
(-8,-5)
Step-by-step explanation:
When you go from quadrant I, where both the X and Y values are positive and rotate 180 degrees you end up in quadrant III, where both X and Y values are negative! Hope this helps :)
Answer:
(-8,-5)
Step-by-step explanation:
A counterclockwise rotation of 180 degrees about the origin changes the original coordinate for ex; (1,-2) to (-1,2)
So, with a counterclockwise rotation of 180 degrees (8,5) to (-8,5)
Mr. Pantera is going to make a histogram of the test scores from the last math test he gave. He plans to first organize the data into a stem-and-leaf plot and then make the histogram from the stem-and-leaf plot. The test scores are listed below.
79, 82, 65, 61, 94, 97, 84, 77, 89, 91, 90, 58, 83, 99, 71, 68, 51, 77, 87, 85
How many bars will his histogram have?
There will be 5 bars because if you have a stem and leaf plot, there will be intervals of 9.

Quadrilateral GHIJ is similar to quadrilateral KLMN. Find the measure of side KL. Round your answer to the nearest tenth if necessary.
Answer:
KL = 11.9 approximately
Step-by-step explanation:
It is stated that the two quadrilaterals are similar
if they are similar then their side lengths are proportional
So we can use that to find KL
JG/NK = GH/KL
(52.5)/17=37/KL cross multiply expressions
52.5*KL = 629 divide both sides by 52.5
KL = 11.9 approximately
