A bag contains 10 pounds of dog food. A family feeds their dogs 0.85 pound of dog food a day. How much dog food is left in the bag after 7 days? Give your answer to the nearest pound.

Answers

Answer 1

Answer: A bag contains 10 pounds of dog food.

A family feeds their dogs 0.85 pound of dog food a day so cin seven day the dog eats (0.85 x 7) = 5.95 pounds

so, dog food is left in the bag after 7 days is (10-5.95) = 4.05 pounds

Answer 2

Answer: Since there is .85 pounds of dog food fed to the dog everyday it saiz that how many are left in 7 days so our equation is 10-7(.85)=x
10-5.95=x
x=4.05
yet is says round it to the nearest pound so its 4 pounds

What is 30% of x is 60

Answers

30% × = 60

30% = $(30)/(`00)$ = 0.3

0.3x = 60

Divide by 0.3 on either sides to isolate x

$(0.3x)/(0.3)$ = $(60)/(0.3)$
x = 200

30% of 200 is 60

Select all functions that have a y-intercept of (0,5).f(x)=7(b)^x-2
f(x)=-3(b)^x-5
f(x)=5(b)^x-1
f(x)=-5(b)^x+10
f(x)=2(b)^x+5

Answers

Answer:

$f(x)=7(b)^(x)-2$

$f(x)=-5(b)^(x)+10$

Step-by-step explanation:

we know that

The y-intercept is the value of y when the value of x is equal to zero

Verify each case

case 1) we have

$f(x)=7(b)^(x)-2$

For x=0

$f(0)=7(b)^(0)-2$

$f(0)=7(1)-2=5$

therefore

The function has a y-intercept of (0,5)

case 2) we have

$f(x)=3(b)^(x)-5$

For x=0

$f(0)=3(b)^(0)-5$

$f(0)=3(1)-5=-2$

therefore

The function does not have a y-intercept of (0,5)

case 3) we have

$f(x)=5(b)^(x)-1$

For x=0

$f(0)=5(b)^(0)-1$

$f(0)=5(1)-1=4$

therefore

The function does not have a y-intercept of (0,5)

case 4) we have

$f(x)=-5(b)^(x)+10$

For x=0

$f(0)=-5(b)^(0)+10$

$f(0)=-5(1)+10=5$

therefore

The function has a y-intercept of (0,5)

case 5) we have

$f(x)=2(b)^(x)+5$

For x=0

$f(0)=2(b)^(0)+5$

$f(0)=2(1)+5=7$

therefore

The function does not have a y-intercept of (0,5)

the base of a right rectangular prism has an area of 173.6 square centimeter and a height of 9 centimeter. what is the volume in cubic centimeter, of the right rectangular prism ?

Answers

Answer: $1562.4\ cm^3$

Step-by-step explanation:

We know that the volume of rectangular prism is given by :-

$\text{Volume}=\text{base area}* \text{height}$

Therefore, for the volume of given rectangular prism the volume will be:-

$\text{Volume}=173.6*9\n\n\Rightarrow\ \text{Volume}=1562.4\ cm^3$

Hence, the volume of the given rectangular prism= $1562.4\ cm^3$

V=l*w*h
or
V=b*h

You already have the width and length multiplied so you only hav eto multiply the height by the area now.
173.6*9=1562.4

The volume of the rectangular prism is 1,562.4 cubic cm
