I need help, figuring out the surface area of this.
Answer:
396 in³
Step-by-step explanation:
You need to find the area of each side, then add them up.
Top and bottom sides: 12*7=84*2=168
Left and right sides: 6*7=42*2=84
Front and back sides: 12*6=72*2=144
168+84+144=396
find all of the zeros algebraically
Answer:
-4, 9, -1
Step-by-step explanation:
x³ - 4x² - 41x - 36
= x²(x + 4) - 8x² - 41x - 36
= x²(x + 4) - 8x(x + 4) - 9x - 36
= x²(x + 4) - 8x(x + 4) - 9(x + 4)
= (x + 4)(x² - 8x - 9)
= (x + 4) (x - 9)(x + 1)
so the zeros of f(x) are: -4, 9, -1

Give the area of the shape below.
Answer: 122 sq. ft.
Step-by-step explanation: First is a have to multiply 13 x 8 to find the area of the rectangle. Next, you have to find the area of the right triangles by multiplying 3 x 3 which would give you the area of two of the right triangles. Multiply 3x3 by 2 to find the area of all four right triangles combined. Finally, add 3 x 3 x 2 (18 sq. ft), to 13 x 8 (104 sq. ft). 18 + 104 = 122 sq. ft.

А
D
829
E
Answer:
Step-by-step explanation:
We know that angles BAD and DAE are supplementary, so the measure of angle DAE is 180-133=47 degrees.
Because of this, we can determine that angle ADE measures 180-82-47=51 degrees.
Now, since triangles ADE and BCE are similar, we can say that the measure of angle ABC is 47 degrees and the measure of angle BCE is 51 degrees.
Finally, to find the measure of angle ADC, we can notice that its the supplement of angle ADE, meaning ADC measures 180-51=129 degrees.

Match the graph with the correct set of equations for the linear system. Then, classify the system as Consistent and Dependent, Consistent and Independent, or Inconsistent. (You should have two answers selected)
Answer:
Inconsistent
4x + 2y = 6 and 4y = -8x + 4
Step-by-step explanation:
Inconsistent: parallel lines, no solutions
Consistent dependent: same line, infinite solutions
Consistent independent: intersects at one point, one solution
Therefore, the pair of lines are INCONSISTENT.
Both lines have negative slopes. As they are parallel, the slopes will be the same for both lines.
Therefore, solution is:
4x + 2y = 6 and 4y = -8x + 4
Because:
4x + 2y = 6 ⇒ y = -2x + 3
4y = -8x + 4 ⇒ y = -2x + 1
Both lines have same slope of -2

Step-by-step explanation:
Twice the difference of a number and four: 2(x - 4)
three times the sum of the number and 2: 3(x + 2)
2(x - 4) = 3(x + 2)
2x - 8 = 3x + 6

Ric is half Paul's age. Tom is 2 years younger than Paul. The sum of all their ages is 33 years Show all working clearly to find Ric's age
Answer:
Ric is 7 years old.
Step-by-step explanation:
Choose variables for everyone's ages. I'll choose [tex]r[/tex] for Ric's age, [tex]p[/tex] for Paul's age, and [tex]t[/tex] for Tom's age.
Since Ric's age is half of Paul's age, we can write this equation:
[tex]r=\frac{1}{2}p[/tex]
Since Tom is two years younger than Paul, we can write this equation:
[tex]t=p-2[/tex]
Since the sum of all their ages is 33 years, we can write this equation:
[tex]r+p+t=33[/tex]
Since we know [tex]t[/tex] and [tex]r[/tex] in terms of [tex]p[/tex], we can replace them in the equation above as follows:
[tex]r+p+t=33\\(\frac{1}{2}p)+p+(p-2)=33[/tex]
Now we can solve for [tex]p[/tex] to find [tex]r[/tex] later:
[tex](\frac{1}{2}p)+p+(p-2)=33\\\frac{5}{2}p-2=33\\\frac{5}{2}p=35\\5p=70\\p=14[/tex]
Now that we know that [tex]p=14[/tex], we can substitute 14 for [tex]p\\[/tex] in the equation[tex]r=\frac{1}{2}p[/tex]:
[tex]r=\frac{1}{2}p\\r=\frac{1}{2}(14)\\r=7[/tex]
Ric is 7 years old.

Answer:
[tex]x=90\\y=-40[/tex]
Step-by-step explanation:
Let's set up a system of equations using the given information.
x+y=50
x-y=130
We can solve this system using elimination. In this case, we can eliminate x by subtracting the two equations.
[tex]x-x+y-(-y)=50-130\\x-x+y+y=50-130[/tex]
[tex]2y=-80[/tex]
Divide both sides by 2.
[tex]y=-40[/tex]
Then, plug -40 in for y to solve for x:
[tex]x+y=50\\x+(-40)=50\\x-40=50\\\text{Add 40 to both sides}\\x=90[/tex]
Therefore..
[tex]x=90\\y=-40[/tex]

The track team needs new uniforms. The students plan to sell plush toy bears (the school mascot) for $5 each. The students find three companies on-line that sell stuffed mascots. Company A sells 15 bears for $43.05. Company B sells 16 bears for $46.24. Company C charges $34.20 for 12 bears. Which company has the best buy?
Answer:
Company C
Step-by-step explanation:
To find the cost of each bear, you must divide each price by the amount of bears. The prices are shown below:
For company A, each bear costs $2.87.
For company B, each bear costs $2.89.
For company C, each bear costs $2.85.
So, the best buy for the team would be Company C.

can anyone help? Estimate the amount of the tip by rounding the bill to the nearest dollar before calculating.
20% tip on a bill of $64.15
Answer:
$12.80
Step-by-step explanation:
You are asked to estimate the tip by rounding the bill amount. The tip is the product of the (rounded) bill amount and the tip rate.
rounded bill = $64.00
tip rate = 20% = 0.20
estimated tip = 0.20 × $64.00 = $12.80

2x = 2
divide by 2 from both sides
/2 /2
x = 1
Answer:
x = 1
Step-by-step explanation:
Step 1: Multiply both sides by 8.
[tex](2.8+2x)/8 * 8 = 0.6 * 8[/tex] [tex]2.8 + 2x = 4.8[/tex]Step 2: Subtract 2.8 from both sides.
[tex]2.8+2x-2.8=4.8-2.8[/tex] [tex]2x=2[/tex]Step 3: Divide both sides by 2.
[tex]2x/2 = 2/2[/tex] [tex]x=1[/tex]Therefore, x = 1.
The perimeter of a rectangular pool is 216 feet. The length of the swimming pool is 3
times longer than the width. Find the length and the width of the swimming pool.
Answer:
l = 81
w = 27
Step-by-step explanation:
l = 3x (x2)
w = x (x2)
l = 6x (has two sides so we x2)
w = 2x
6x + 2x = 8x
8x = 216
x = 27 (divide both sides)
w = 27
l = 27 x 3 = 81 (length is 3x bigger than width)
81 + 81 + 27 + 27 = 216

You save $35 each week. You now have $140. You plan to save enough money for a cruise that costs $1,050. Write and solve an equation to find the number of weeks it will take to save for the cruise.
Answer:
It will 26 weeks to save for the cruise starting from a balance of $140
(It will take 30 weeks in total, if you start saving from $0)
Step-by-step explanation:
let x = number of weeks
Given starting balance = $140
⇒ 140 + 35x = 1050
⇒ 35x = 1050 - 140
⇒ 35x = 910
⇒ x = 910 ÷ 35
⇒ x = 26

degrees.
What type of triangle does this create?
A. obtuse
B. right
C. equilateral
D. isosceles
Considering that it has an angle of 90º degrees, the triangle is classified as:
B. right
How are triangles classified according to the largest measure of their angles?If the largest measure is greater than 90º, the triangle is classified as obtuse.If it is equals to 90º, the triangle is classified as right.If it is less than 90º, the triangle is classified as acute.In this problem, two angles are 40º and 50º. Since the sum of the angles is of 180º, we have that:
x + 50 + 40 = 180
x = 90º.
Hence, it is a right triangle, and option B is correct.
