Answer:

b + b - 10 = 190

⇒ 2b - 10 = 190

Step-by-step explanation:

Let b = number of bugs Andrew collected

⇒ b - 10 = number of bugs Thomas collected

Given total number of bugs = 190

b + b - 10 = 190

To solve:

b + b - 10 = 190

⇒ 2b - 10 = 190

⇒ 2b = 200

⇒ b = 100

Therefore, Andrew colleted 100 bugs and Thomas collected 90 bugs.

50% prefferd fruit cake 1/5 preferred spong and the remainder preferred cheesecake

d1i1m1o1n [39]

The percentage of people who preferred cheesecake if 50% prefferd fruit cake 1/5 preferred sponge is 40%.

<h3>Percentage</h3>

Total percentage = 100%
Fruit cake = 50%

Percentage remaining = 100% - 50%

= 50%

Sponge cake = 1/5

Percentage of sponge cake = 1/5 × 50%

= 1/5 × 0.5

= 10%

Percent that likes cheesecake = Total - (fruits cake + sponge cake)

= 100% - (50% + 10%)

= 100% - (60%)

= 40%

Therefore, the percentage of people who preferred cheesecake if 50% prefferd fruit cake 1/5 preferred sponge is 40%.

The area of a cross section perpendicular to the base of a rectangular prism is 45 square inches. If the length and width of the

Naily [24]

The height of the prism is $2.25 \ in$

Explanation:

It is given that the area of the cross section of the rectangular prism is 45 square inches.

Length of the rectangular prism is $5 \ in$

Width of the rectangular prism is $5 \ in$

To determine the height of the prism, let us substitute these values in the formula $SA=(2l+2w)h$ , we get,

$45=(2(5)+2(5))h$

Multiplying the terms within the bracket, we get,

$45=(10+10)h$

Adding the terms within the bracket, we have,

$45=20h$

Dividing both sides by 20, we get,

$2.25=h$

Thus, the height of the rectangular prism is $2.25 \ in$
