First: let’s get Ben’s current age:
16+4=20

Next let’s get Dunn’s current age:
4/7=20/x
Cross multiply and divide:
x=35

Let’s now add 10 to both ages:
Ben 20+10=30
Dunn 35+10=45

Lastly, let’s find the lowest common multiple of 30 and 45 to determine the ratio:
30:45
Both 30 and 45 can be divided by 15.
30/15=2
45/15=3

Answer:
2:3

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 $2.25 \ in$

Which function is linear?

jeka57 [31]

Answer:

Step-by-step explanation:

Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:

A). When x is an absolute value, the line will not be linear because an input will have two outputs.

B). x cannot be in the denominator of a fraction for the line to be linear

D). Once again, x cannot be an absolute value.

*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.

Brian invests £7900 into his bank account.

DENIUS [597]

Step-by-step explanation:

1. use the equation

current amount X interest to the power of years

commpound interest is 2.3%

The starting value is £7900

So: £7900*1.023^5=£8851.26

Therefore, the answer is £8851.26 after 5 years of interest added
