Answer:
Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p
Step-by-step explanation:
Let's
p = area covered by a can of paint
W = the total area of the walls
n = number of paint cans to buy
Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p
That is,
n = W / p
If the total area of the walls = 100 m²
A can of paint covers 5 m². Find the number of cans of paint needed?
Number of paints to buy, n = The total area of the walls, W / Area covered by a can of paint, p
n = W / p
= 100 m² / 5 m²
n = 20 cans of paint

Miyoko bought 3 packages of tape that each had 1 yard 2 feet of tape in them how many inches of tape did miyoko buy?
Answer: 180 inch
Step-by-step explanation:
Given
Miyoko bought 3 packages of tape
Each tape has 1 yard and 2 feet of tape
[tex]1\ \text{yard}=3\ \text{foot}[/tex]
[tex]1\ \text{ft}=12\ \text{inch}[/tex]
converting yard to feet
[tex]\Rightarrow 3+2=5\ ft[/tex]
Convert feet to the inch
[tex]\Rightarrow 5\times 12=60\ \text{inch}[/tex]
For 3 tapes, it is
[tex]\Rightarrow 60\times 3=180\ \text{inch}[/tex]
Thus, the total tape is [tex]180\ \text{inch}[/tex]

A cylinder has a volume of 791.28 cubic centimeters. The height of the cylinder is 7.0 inches. Calculate the radius of the cylinder. Use 3.14 for π.
Answer:
The radius is 6
[tex] \sqrt{v \div \pi \times h =} [/tex]
=791.28/3.14×7.0
=
[tex] \sqrt{36} [/tex]
=6
The radius of cylinder is 3.764 cm.
What is volume?Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.
Finding an object's volume can help us determine how much material is needed to fill it, such as how much water is needed to fill a bottle, aquarium, or water tank.
Given volume of cylinder = 791.28 cm³
height = 7.0 inches
so, 1 inch = 2.54 cm
7 inch = 2.54 x 7 = 17.78 cm
height = h = 17.78 cm
volume of cylinder = πr²h
where r = radius
V = πr²h
791.28 = 3.14(17.78)r²
r² = 791.28/55.8292
r² = 14.1732
r = √14.17732
r = 3.764 cm
Hence the radius is 3.764 cm.

B) 704 ft
C) 560 ft
D) 590 ft
Answer:
C
Step-by-step explanation:
10*8*12 = 960
16*10 = 160
960+160= 1120
1120 ÷ 2 = 560
Answer:
I'll setup the formula and you can do the calculations.
Step-by-step explanation:
you need to add up the areas of 2 rectangles (10x16), 1 rectangle on the bottom (12x16) and 2 triangles ( height = 8 and base = 12)
area of rectangle = wide x length
area of triangle = 1/2 base x height

There are 5 green skittles, 4 orange skittles, and 3 red Skittles in a bag. What is the probability of red Skittle, Not replacing it (eating it), then picking a green skittle?
Answer:
3/12
Step-by-step explanation:
the entire bag has 12 skittles. there are only 3 red. This gives a fraction of red skittles/entire bag in order to get the probability. So this would be 3/12 in this most basic sense? I am not sure if you need to go further than this or not. Hope this helps!

You flip a coin 50 times. Of the 50 flips, the coin landed on heads 30 times. Use the questions below to compare the experimental probability of flipping heads with the theoretical probability of flipping heads.
Given:
Of the 50 flips, the coin landed on heads 30 times.
To find:
The experimental probability of flipping heads and compare it with the theoretical probability of flipping heads.
Solution:
We have,
Total number of trials = 50
Total number of heads = 30
The experimental probability of flipping heads is:
[tex]\text{Experimental probability}=\dfrac{\text{Total number of heads}}{\text{Total number of trials}}[/tex]
[tex]\text{Experimental probability}=\dfrac{30}{50}[/tex]
[tex]\text{Experimental probability}=\dfrac{3}{5}[/tex]
[tex]\text{Experimental probability}=0.6[/tex]
A coin has two sides one is heads and another is tails. So, the theoretical probability of flipping heads is:
[tex]\text{Theoretical probability}=\dfrac{1}{2}[/tex]
[tex]\text{Theoretical probability}=0.5[/tex]
Therefore, the experimental probability of flipping heads is 0.6 and the theoretical probability of flipping heads is 0.5. So, the experimental probability is greater than the theoretical probability of flipping heads.

B.)A=28,B=34
C.)A=35,B=28
D.)A=34,B=28
Answer:
D. A=34, B=28
Step-by-step explanation:
In the bulletin points, it says that seconds 3-5 are decreasing. That means that those heights can't be higher than second 2 (34). The only option that works is option D.
----------------------
Option A is incorrect because it starts with 35ft which is higher than second 2(34) so that is automatically wrong.
Option B is incorrect because it is increasing instead of decreasing.
Option C is incorrect for the same reason as Option A: it starts with 35ft.
---------------------
Therefore, the only correct option is Option D.
