Step-by-step explanation: Answer is a

Answer:

78 cm^2

Step-by-step explanation:

This will require 3 steps.

1) Area of the entire rectangle

18cm * 8 cm = 144 cm^2

2) Area of the square with one side length of 9cm

The missing measurement for the heights below 2cm

8cm - 2 cm = 6 cm

This area will be 6cm * 9 cm = 54 cm^2

3) Triangle

You have your height, which is 6cm

You also have your base, 18 cm total length minus the 5 cm stated minus the 9 cm also stated.

18cm - 5cm - 9 cm = 4 cm

The area of a triangle is A= h b/2

A = 6 * (4/2)

A = 12 cm^2

Now substract the sum of the smaller rectangle and the triangle from your large triangle

144 - 54 - 12

Answer:

72°

Step-by-step explanation:

∠ AOB = 20% of 360° = 0.2 × 360° = 72°

arc AB is equal to the angle subtended at the centre , that is

arc AB = 72°

Answer:

the equality is false the correct solution is

[tex]4.5 \times 104 \\ (4 + 0.5) \times 104 \\ 4 \times 104 + 0.5 \times 104 \\ 416 + 52 \\ = 468[/tex]

Answer:

The answer would be B because the y intercept is how much he changes per hour

Answer:

Your answer should be C

Step-by-step explanation:

Letter A was tempting, but 120 for 1 hour. Then 180 for 2.5 means that is had a y intercept. So it couldn't be A. The other ones were easy to rule out because they only told a fraction of what was shown.

Answer:

1.What is the y- intercept of the function?

2.What is the first difference?

The difference in values of consecutive f(x):

This is also called the slope if the relationship is linear.

3.Write an equation to represent the function given in the table.

Based on the information above we have:

The equation is:

Answer:

420cm^3 (cubed) = volume when tripled

Step-by-step explanation:

1. when you multiply 7*4*5=140 (volume of the prism originally)

2. 140*3=420 (final answer)

Answer:

A. 140 cm

B. 3780 cm

Step-by-step explanation:

The volume formula for a rectangular prism is lwh, and 7 times 4 times 5 equals 140.

If you triple all those amounts, then you get 21 (7 times 3), 12 (4 times 3), and 15 (5 times 3), and when you multiply those you get 3780.

Answer:

Step-by-step explanation

Each week a discount of 15% of the previous week.So the price will be 85% of the previous week (17/20 of the previous price)

We multiply the price from the previous week  by 0.85 to obtain the new price  

200 x 0.85 = 170

170 x0.85 = 144.50.....and so on

3)$ 122.82

4$)104.40

5).$88.74

6)$75.42

The shoes will be less than half in week 5

 DECAY

The friend is not right

$30 less was only the first week

Each week the saving will be 85% of the  previous week. But the shoes will not be free in 2 months  On the week 8 the price will be $54.50

Answer:

Your answer is 4 books per month.

Step-by-step explanation:

A really simple way to solve this is to simply divide 64 by 16, and you get 4. You have to read 4 books per month to reach 64 books in 16 months.

Given:

In circle L, measure of angle KLM is 54 degrees and KL = 10 units.

To find:

The length of arc KM.

Solution:

The formula for arc length is:

[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex]          ...(i)

Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle in degrees.

The measure of KL is 10 units, it means the radius of the circle L is 10 units.

The measure of angle KLM is 54 degrees, it means the measure of central angle on arc KM is 54 degrees.

Putting [tex]\pi=3.14, r=10,\theta=54^\circ[/tex] in (i), we get

[tex]s=2(3.14)(10)\times \dfrac{54^\circ}{360^\circ}[/tex]

[tex]s=20(3.14)\times 0.15[/tex]

[tex]s=9.42[/tex]

Therefore, the length of arc KM is 9.42 units.

Answer:

[tex]-\frac{3p^8}{4q^3}[/tex]

Step-by-step explanation:

[tex]\frac{15p^{-4}q^{-6}}{-20p^{-12}q^{-3}}[/tex]  can be broken down into three fractions, coefficients, powers of p, powers of q.

[tex]-\frac{15}{20}\cdot\frac{p^{-4}}{p^{-12}}\cdot\frac{q^{-6}}{q^{-3}}[/tex]

Simplify the first fraction, then simplify the others by subtracting numerator exponents minus denominator exponents.

[tex]-\frac{3}{4} p^{-4-(-12)} q^{-6-(-3)} =-\frac{3}{4} p^8 q^{-3} = \alpha -\frac{3p^8}{4q^3}[/tex]

Answer:

88 square inches

Step-by-step explanation:

A circular plate has circumference 33.3 inches.

Step 1

We find the radius

The formula to find the radius go a circle given circumference is

= C /2π

r = 33.3/2 × 3.14

r = 5.3025477707 inches

Approximately to the nearest thousandth = 5.303 inches

Step 2

What is the area of this plate? Use 3.14 for Pi.

The area of a circle = πr²

Where

π = 3.14

r = 5.3025477707 inches

Hence

Area of the circle = 3.14 × (5.303inches)²

= 88.30248026 square inches

Approximately to the nearest whole number the area of the circle = 88 square inches

The area of this plate is about 88 square inches.

Answer:

about 703.69

Step-by-step explanation:

To calculate the base you would use pi radius squared: 153.93

Since you have 2 bases you would multiply that by 2: 307.87

Then you need to find the circumference (2 pi radius) : 43.98

Then you multiply the circumference by the height: 395.82

Add the bases and the sides to get 703.69
