Answer:

8: 73.2 cm

10: 738 mm

Step-by-step explanation:

8: A= 12.2 (4.5 + 7.5) / 2 --> 146.2 / 2 = 73.2 cm

10: A= 36 (22 + 19) / 2 --> 1,476 / 2 = 738 mm

Answer:

8: 73.2

10: 738

Step-by-step explanation:

Area of a trapezoid = [tex]A=\frac{a+b}{2} h[/tex]

where a and b = base lengths and h = height

For #8

These are the given dimensions

Base 1 = 4.5

Base 2 = 7.5

Height = 12.2

All we have to do is plug in the values into the formula

So....

[tex]A=\frac{4.5+7.5}{2} 12.2\\4.5+7.5=12\\\frac{12}{2} =6\\6*12.2=73.2[/tex]

Hence the answer is 73.2cm²

For #10

Once again all we have to do is plug in the values into the formula

[tex]A=\frac{22+19}{2} 36\\22+19=41\\\frac{41}{2} =20.5\\20.5*36=738[/tex]

Hence the answer is 738

Answer:

f(x)=2x53it[4p[

Step-by-step explanation:

Answer:

f(x)=2x53it[4p[

Step-by-step explanation:

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.  

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

Step-by-step explanation:

I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!

Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.

Figure 1: 15×4=60 cm

Figure 2: 18×3=54 cm

Figure 3: 11×6=66 cm

Figure 4: 12×5=60 cm

As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

Answer:$8.50

Step-by-step explanation: If 4 apples are $1.00 that means that one apple would be 25¢. 10 apples would mean $8.00 and since 2 apples are left that would be 50¢. Hence, the answer would be $8.50

7. The area is [tex]\frac{6}{7}[/tex]

8. 70 - (20-13) would probably work

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

Answer:

-5 down 6 across

Step-by-step explanation:

Answer:

Step-by-step explanation:

There is (-2,3), (6,3), and (-2,-3)

The first number for each one is the x position, the horizontal line,-2, 6, and -2

The second number is the y position, vertical line, 3, 3, and -3

The last point you need to plot on the graph is (6,-3), 6 is the x position, and -3 is the y position

Answer:

C. {(1,H), (2,H), (3,H), (4,H), (1,T), (2,T), (3,T), (4,T)}

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

                                                       = j + 0.08j

                                                       = 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
