Answer:
h = 3 cm
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = Ah ( A is the area of the base and h the height )
Here V = 36 and A = 6 × 2 = 12 cm² , then
12h = 36 ( divide both sides by 12 )
h = 3
Answer: 3 cm
Step-by-step explanation:
The formula to solve the volume of a rectangular prism is V = l x w x h
Where V is volume, l is length, w is width, and h is height
Givens are, Volume = 36 cm3
length = 6 cm
width = 2 cm
Now, we will plug in the numbers to the formula
36 cm3 = 6cm x 2cm x h
36 cm3 = 12 cm2 x h
divide 12cm2 on both sides
36cm3/12cm3 = h
h = 3cm

Annie earns $15 per hour babysitting. How many hours will it take her to earn $60?
Answer:
4 hours
Step-by-step explanation:
15 x 4 = 60
$60
Answer:
4 hours.
Step-by-step explanation:
We are looking for the amount of money Annie will need to earn 60.
Let the equation be 15+x=60.
The equation could be represented as 15+x=60, or 60-15=x.
The easier solution would be to subtract.
When we subtract 60-15 we get 45, therefore the value of x is 45 making the statements true.
15+45=60 and 60-15=45 as well.
We know she earns 15 an hour, so we have to see how many 15 we can add up to get to 60.
15+15+15+15=60, therefore she will need to work 4 hours.
X - 2y = -3
2x + y = -1
Answer:
y = 1
x = -1
Step-by-step explanation:
x - 2y = -3, then x = 2y - 3
2x + y = -1
substitute for x:
2(2y - 3) + y = -1
4y - 6 + y = -1
5y = 5
y = 1
x = 2 - 3 = -1
Answer:
it can only be simp[lified
so it will be
(x+2x)+(y+2y)=-3-1
3x+3y=-4
cannot be solved further

Mr. Hernandez bought 16 meters of
chain-link fencing. The section of his yard that
needs to be fenced is 50 feet long. Did Mr.
Hernandez buy enough fencing? Determine the
number of feet Mr. Hernandez still needs to buy
or how many extra feet he has purchased.
(1 meter = 3.28 feet.)
Answer:
well yes he has 2.4 extra
Step-by-step explanation:
1 meter is 3.28 feer so 3.28 x 16 is 52.4 and he only need 50.
hoped this hlepd and you have to give me brailyest. i just want to help...
Answer:
yes
Step-by-step explanation:
well we can just multiply the 3 with the 16
well now we have 48
add 28, 16 times which gives us 4.48
48+4.48 52.48
you have 2.48 feet left
and yes he has enough
now, about that deal.....

The time t required to drive a certain distance varies inversely with the speed r. If it takes 2 hours to drive the distance at 40 miles per hour, how long will it take to drive the same distance at 45 miles per hour?
A. 80 hours
B. 900 hours
C. about 1.78 hours
D. 2.25 hours
Answer:
C. about 1.78 hours
Step-by-step explanation:
Answer:
1.78 hours
Step-by-step explanation:
If t varies inversely with the speed, the formula for that is t= \frac{k}{r} . If t = 2 and r = 40, then we can solve for k, the constant of variation. Multiply both sides by 40 to get k = 80. Now we need to find the value for t when r = 45. Using the k value we just solved for, we will fill in the equation as t= \frac{80}{45} for a t value of about 1.78 hours
...............................................................................................................................................
Answer: about 1.78 hours
...............................................................................................................................................
t = k/r
2 = k/67
k = 134 (which happens to be the distance)
t = 134/r
t = 134/55
t = 2.436 hours
...............................................................................................................................................
The formula for this is t = k/r, read "t varies inversely as r". If the info they give us is 4 hours and 35 miles per hour, we find that k = 140. Now use that 140 in another equation to solve for t: t = 140/45, and t = 3.1 hours
...............................................................................................................................................
t = k/r\
4 hours and 35 miles per hour,
we find that k = 140.
Now use that 140 in another equation to solve for t:
t = 140/45, and
t = 3.1 hours

P=initial principal balance
r=interest rate
n=times applied per [time (eg year)]
t=number of time periods gone by
The expression: 2500(1.04)^x
The expression: 2500(1+1/25)^(nt)
1.04=1+1/25=increases by 4% each year

A 26 foot ladder is set against the side of a house so that it reaches up 24 feet. If Mila
grabs the ladder at its base and pulls it 12 feet farther from the house, how far up the side of the house will the ladder reach now?
Answer:
13.9
Step-by-step explanation:
13.85 feet far up the side of the house will the ladder reach now.
Given that, a 26 feet ladder is set against the side of a house so that it reaches up 24 feet.
What is heights and distances in trigonometry?In mathematics, you can calculate the height of an object using the distance and angles. Here distance is the horizontal distance between the object and the angle is the angle above the horizontal of the top of the object, which gives the height of the object.
Let the distance between base of house to foot of the ladder be x.
Using Pythagoras theorem 26²=24²+x²
⇒ 676 = 576 + x²
⇒ x² = 100
⇒ x =10 feet
Mila grabs the ladder at its base and pulls it 12 feet farther from the house.
Now, the distance between base of house to foot of the ladder = x+12
= 10+12 = 22 feet.
So, up the side of the house the ladder reach = 24-h
Then, 26² = (24-h)²+22²
⇒ 676 = (24-h)²+484
⇒ (24-h)² = 192
⇒ (24-h) = √192
⇒ (24-h) = 13.85
⇒ h = 24-13.85
⇒ h = 10.15 feet
Therefore, 13.85 feet far up the side of the house will the ladder reach now.

Answer:
The length is 5 inches and the width is 4 inches
Step-by-step explanation:
Steffie makes a scale drawing for a crate with a scale factor of 1:3. The dimensions of her scale drawing are 15 inches long by 12 inches wide. The builder creates a scale drawing of the crate with a scale factor of 1:9. What are the dimensions of the builder's scale drawing? A. The length is 4 inches and the width is 5 inches B. The length is 45 inches and the width is 36 inches. C. The length is 5 inches and the width is 4 inches. D. The length is 36 inches and the width is 45 inches
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
dimensions of the image steffie scaled = (15 x 3) by (12 x 3) = 45 by 36
Builders scaled image = (45 / 9) by (36 /9) = 5 by 4
