$\frac{10+12+x}{3} = 15\\\\10 + 12 + x = 45\\\\22 + x = 45\\\\\huge{\boxed{x = 23}|$

10 + 12 + 23 ÷ 3 = 15
22 + 23 ÷ 3 =15
45 ÷ 3 = 15

The missing number would be 23 since 22 + 23 is 45 and 45 divided by 3 is 15.
Hope this helped :)

Suppose that a household's monthly water bill (in dollars) is a linear function of the amount of water the household uses (in hu

notsponge [240]

The monthly cost for 17 hundred of cubic feet is $52.13.

<h3>What is a linear equation?</h3>

A linear equation is in the form:

y = mx + b

Where y,x are variables, m is the rate of change and b is the initial value of y.

Let y represent the bill paid for x HCF of water.

The slope is 1.45, hence m = 1.45.

The monthly cost for 13 HCF is $46.33, hence:

46.33 = 1.45(13) + b

b = 27.48

y = 1.45x + 27.48

For 17 HCF:

y = 1.45(17) + 27.48 = 52.13

The monthly cost for 17 hundred of cubic feet is $52.13.

Tarinda's corn plant was 7- 1/3 inches tall at the end of Week 1. The corn plant was 18 1/2 inches tall at the end of Week 2. Ho

Answer:

The corn plant grew by 11.17 inches during week 2.

Step-by-step explanation:

7 and 1/3 inches tall at the end of Week 1.

The height at the end of week 1, as a simple fraction, is:

$7 + \frac{1}{3} = \frac{3*7 + 1}{3} = \frac{22}{3}$

The corn plant was 18 1/2 inches tall at the end of Week 2.

At the end of week 2, the height will be of:

$18 + \frac{1}{2} = \frac{18*2+1}{2} = \frac{37}{2}$

How many inches did the corn plant grow during Week 2?

Height at the end of week 2 subtracted by the height at the end of week 1. So

$\frac{37}{2} - \frac{22}{3} = \frac{3*37-2*22}{6} = \frac{67}{6} = 11.17$

The corn plant grew by 11.17 inches during week 2.

What are the dimensions of the pond? Please help.

balu736 [363]

Let's assume

length of box is l

width of box is w

we know that

area of rectangle = length*width

$21=l*w$ ...................(1)

now, we are given

fencing length is 20 foot

fencing length will be equal to perimeter

and we know that

$perimeter=2(l+w)$

so, we get

$2(l+w)=20$

now, we can solve for l

$l=10-w$

now, we can plug that in first equation

$21=(10-w)*w$

now, we can solve for w

$10w-w^2=21$

$w^2-10w+21=0$

$(w-7)(w-3)=0$

$w=7 , w=3$

now, we can find length

$l=10-3=7$

$l=10-7=3$

so, option-B..................Answer
