Answer:

Answer:

Answer: Good thing you provided the image!

Working down the columns:

C base= 2

D base = 4

C height =3

D height = 2

C area = bh = 8

D area = bh = 8

Step-by-step explanation:

Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.

The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.

A trailer will be used to transport several 40 kilogram crates to a store. the greatest amount of weight that can be loaded onto the trailer is 1,050 kilograms. An 82 kilogram crate has already been loaded onto the trailer. what is the greatest number of 40 kilogram crates that can be loaded onto the trailer

Answers

Ok say that x is the greatest number of 40 kg crates that can be loaded to the transport.
then 40x+82 must be at most 1050 kg because its the weight that the transport can handle
so that means algebraically 
40x+82<= 1050
solve this inequality 
40x+82-82<= 1050-82
40x<=968

40x/40 <= 968/40
x<= 24.2
so the greatest amount of 40 kg crates you can add is 24 crates
82+crates is less than or equal to 1050
crates=40 times number of crates (c)
82+40c≤1050
minus 82 both sides
40c≤968
divide both sides by 40
c≤24.2
round down since we can't put 0.2 crates on
24 crates is max number we can add

A line contains (4,2) and (0,1) what is the equation of the line

Answers

First we need to find the slope of the line.

Slope = (y_2-y_1)/(x_2-x_1) = (2 - 1)/(4-0) = (1)/(4)

Our equation of the line will be in the form of y = mx + b, where m is the slope and b is the y-intercept.

We have found the slope. All we need to find is the y-intercept. Luckily, they gave us the y-intercept!

The y-intercept can be found when x = 0. And one point they gave us is (0,1). That means the y-intercept is 1.

The equation of the line is 

y = (1)/(4)x + 1
When you need the equation of a line, you need to find the slope (m) and the y-intercept (b). the slope is fairly easy to find, we simply find the second y- the first y divided by the difference of the second x and the first x. this will look like
(1-2)/(0-4)= 1/4. that is our slope. next we need to find the y-intercept, that is when x=0. for this problem we are actually given it with the second point (0,1) that means our y-intercept is 1. now we have the everything we need for the equation y=mx+b. we know that m=1/4 and b=1, so we can plug that in and get y=1/4x+1

What multiples of 4 are not factors of 48?

Answers

Multiples of four:
4, 8, 12, 16, 24, 28, 32, 36

Is 4 a factor of 48?
48/4=12
Yes, so that means 4 is not the answer.

Is 8 a factor of 48?
48/8=6
Yes, so that means 8 is not the answer.

Is 12 a factor of 48?
48/12=4
Yes, so that means 12 is not the answer.

Is 16 a factor of 48?
48/16=3
Yes, so that means 16 is not the answer.

Is 24 a factor of 48?
48/24=12
Yes, so that means 24 is not the answer.

Is 28 a factor of 48?
48/28= irrational number
No, so that means 28 is the answer.

Is 32 a factor of 48?
48/32= irrational number
No, so that means 32 is the answer.

Is 36 a factor of 48?
48/36= irrational number
No, so that means 36 is the answer.

Answer: 28, 32, 36
There is 20, then there's bunches of even numbers after the number 48. Also there's 28, 32, 36, 40 and 44.

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

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
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
