Answer:

4 sqrt(5); 41.0

Step-by-step explanation:

Question 7:

Using Pythagoras theorem:

y = sqrt(12^2 - 8^2)

y = sqrt(80)

y = 4 sqrt(5)

Question 8:

A = Area rectangle + Area circle

A = 2.4 × 4.4 + pi × 4.4^2 ÷ 2

A = 10.56 + 9.68 pi

A = 41.0

Step-by-step explanation:

<em>Answer</em><em> </em><em>1</em><em> </em><em>to find the base</em><em> to apply the Pythagoras </em><em>theorem.</em><em>.</em><em>of</em><em> </em><em>finding</em><em> </em><em>length</em><em>.</em><em>.</em>

<em>Hypotenuse²</em><em>=</em><em> </em><em>Base²</em><em>+</em><em> </em><em>Height</em><em>²</em>

<em>So,</em>

<em>(</em><em>H</em><em>)</em><em>²</em><em>=</em><em> </em><em>(</em><em>B)</em><em>²</em><em>+</em><em>(</em><em>H)</em><em>²</em>

<em>1</em><em>2</em><em>²</em><em>=</em><em> </em><em>8</em><em>²</em><em>+</em><em>y²</em>

<em>1</em><em>4</em><em>4</em><em>-</em><em>6</em><em>4</em><em>=</em><em>y²</em>

<em>8</em><em>0</em><em>=</em><em>y²</em>

<em>√</em><em>8</em><em>0</em><em>=</em><em> </em><em>y</em>

<em>√</em><em>2</em><em>×</em><em>2</em><em>×</em><em>2</em><em>×</em><em>2</em><em>×</em><em>5</em><em>=</em><em> </em><em>y</em>

<em>2</em><em>×</em><em>2</em><em>√</em><em>5</em><em>=</em><em> </em><em>y</em><em> </em><em> </em><em>(</em><em> </em><em>take</em><em> </em><em>one</em><em> </em><em>2</em><em> </em><em>from</em><em> </em><em>each</em><em> </em><em>pair)</em>

<em>4</em><em>√</em><em>5</em><em>=</em><em> </em><em>y</em>

Marta_Voda [28]

This question is incomplete

Complete Question

A baseball team had $1,000 to spend on supplies. The team spent $185 on a new bat. New baseballs cost $4 each.

The inequality 185 + 4b ≤ 1,000 can be used to determine the number of new baseballs (b) that the team can

purchase. Which statement about the number of new baseballs that can be purchased is true?

A. The team can purchase 204 new baseballs.

B. The minimum number of new baseballs that can be purchased is 185.

C. The maximum number of new baseballs that can be purchased is 185.

D. The team can purchase 185 new baseballs, but this number is neither the

maximum nor the minimum.

Answer:

D. The team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

Step-by-step explanation:

The first step would be to solve the given equation:

185 + 4b ≤ 1000

4b ≤ 1000 - 185

4b ≤ 815

Divide both sides by 4

b ≤ 203.75

The maximum amount of baseballs the team can buy is 203. This means that they can buy 203 or less than that amount.

Of all the options give, option D is the correct option because the team can purchase 185 new baseballs, but this number is neither the maximum nor the minimum.

The maximum number of ball they can buy is 203 balls and the minimum is zero.

At a school, there are 120 athletes. The ratio of boy athletes to girl athletes is 3:5. How many of the athletes are girls?
FinnZ [79.3K]
There are 75 girls because you add the ratio 3+5 = 8 then divide 120 by 8 to get 15 then there are 5 lots of girls so multiply 15 x 5 to get 75

hope this helps !
