with three cans of paint u can paint 2 walls with 2 layers. How many cans do u need to paint 10 walls with 3 layers?
Answer:
22.5 cans of paint
Step-by-step explanation:
[tex]n=3*10*\frac{3}{2*2} =30*\frac{3}{4} =22.5 cans[/tex]
Answer:
You need 22.5 cans of paint to paint 10 walls with 3 layers.
Step-by-step explanation:
[tex]\frac{3}{2*2}[/tex] = 0.75 (Represents how many cans of paint it takes to paint 1 wall with 1 layer)
0.75 * 10 * 3 = 7.5 * 3 = 22.5 (The number of paint needed for 1 wall with 1 layer multiplied by 10 walls with 3 layers to get the total amount of paint needed)

Answer:
6m
Step-by-step explanation:
You need to use trigonomtery: SOHCAHTOA
Since we are looking for the height, we should use the Sine rule:
Sine(37) = opposite/hypotenuse
We already have our hypotenuse which is 10
sine(37) = opposite/10m
Now we re-arrange to find the opposite(which is our height)
opposite = 10m x sine(37)
opposite = 6.018
Therefore height = 6 to the nearest metre
Hope this helps :)
Find the solution to the following system of equations using substitution or elimination y=-2x+7 y=3x-8
Answer:
x = 3, y = 1
Step-by-step explanation:
By substitution since y = -2x + 7, substitute that for the 2nd y so
-2x +7 = 3x - 8, so x = 3, then substitute the 3 in any of the equations, so y = -2(3) + 7 is equal to 1
If you use elimination you can subtract the two equations from each other to get rid of the y so
y = -2x + 7
-y = -3x + 8
so 0 = -5x + 15, 5x = 15, x=3
After an office party, 4 1/3 pizzas are left. A day later, there are 1 5/6 pizzas left. How munch pizza was eaten during the day after the party
Answer:
15/6 pieces of pizza were eaten. Which is equivalent to 2.5. So 2.5 pizzas were eaten.
Step-by-step explanation:
Just did the math. Convert 4 1/3 to 0/6. So 1 times 2 is 2, and 3 times 2 is 6. Which would give you 4 2/6 which has the same denominator as 1 5/6.

Nick decides to play "Spin to Win" at a fundraiser event. He has a 25% chance of winning on any individual spin.
Individual spins are independent. Nick decides to play the game 10 times.
What is the probability that Nick wins at least once?
Round to 2 decimal places,
Answer:
0.015625
Step-by-step explanation:
The probability that Nick wins at least once is 2.5
What is probability?"Probability is finding out the possibilities of the occurrence of an event."
Formula to find the probability of an event:"P(A) = n(A) / n(S)
where, n(A) is the number of favorable outcomes of an event A
n(S) is the total number of outcomes for an experiment"
What is percent?"It is a number that can be expressed as a fraction of 100."
For given example,
Nick has a 25 percent chance of winning on any individual.
This means, his chances of winning on any individual spin are 0.25
Individual spins are independent and Nick decides to play the game 10 times.
So the probability that Nick wins at least once is 10 × 0.25 = 2.5
Therefore, the probability that Nick wins at least once is 2.5

A milk truck is driving around town. What is the volume of the milk truck?
Length: 6
Width: 4
Height: 6
Answer:
[tex]144[/tex] cubic units
Step-by-step explanation:
We can assume that the truck is a rectangular prism since we're given its length, width, and height. To find the volume of a rectangular prism, simply multiply its length, width, and height together. As an algebraic expression, this would be [tex]l*w*h[/tex], where [tex]l[/tex], [tex]w[/tex], and [tex]h[/tex] are the prism's length, width, and height, respectively.
In this case, we are given that [tex]l=6[/tex], [tex]w=4[/tex], and [tex]h=6[/tex]. Therefore, the volume of the milk truck is [tex]6*4*6=144[/tex] cubic units. Hope this helps!
Answer: 144 feet³
Step-by-step explanation: To find the volume, mutiply the Length, Width, and Height. Or we can use the formula.
Rectangular Tank Volume Formula: L x W x H
As we see, 6 is the Length. 4 is the Width and 6 is the Height.
So, we can multiply the Length, Width, and Height to get the volume.
6 x 4 x 6 = 144 feet³
Therefore, the answer is 144 feet³

Answer:
Option c = [tex]\sqrt[9]{3}[/tex]
Step-by-step explanation:
One side = 18
Bottom side = 18 (equalateral triangle)
we can use phytagorues theorum:
a = the altitude (unknown)
b= one side (half of the bottom side) = 18/2 = 9
c = hypothenus = 18 (given)
a^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 = 18^2 - 9^2
a^2 = 243
a = [tex]\sqrt{243}[/tex] = [tex]\sqrt{ 3 x 3 x 3 x 3 x 3 }[/tex] = [tex]\sqrt[9]{3}[/tex]

There is a flu outbreak at your school that starts with 10 people. The number of ill students increases by 20% each hour. Write an exponential function to represent the total number of ill students, f(x), where x is the number of hours after the outbreak. How long does it take for at least 100 people to be ill with the flu?
please explain how you do the problem
thank you
Answer:
y = (10 * 0.2) ^ x
Y = (2)^x
Y = 2^x + 10
6.5 hours
Step-by-step explanation:
Y is the number of people at the school who have been infected with the flu. The 10 is the initial number of infected students which is a constant so it does not change. The 0.2 is the rate of increase, or 20%. The x exponent is the number of hours so that is a changing number. Your answer is 2 to the power of the number of hours which is x. Add ten after that to get your number. to get 100 people ill, it would take about 6.5 hours.

A mountain bike originally priced at $960.00 is up for sale at a discount of 14%. What is the price of the mountain bike after the discount?
Answer:
$825.60
Step-by-step explanation:
Since the price of it is $960.00, it means that it's 100%.
100% = 960
1% = 960 ÷ 100 = 9.6
14% = 9.6 x 14 = 134.40
Since they asked for after the discount, deduct the price of the discount with the original price.
Mountain bike after 14% discount =
960 - 134.40 = 825.60

<HAM=180-<HAJ=180-42=138IS YOURANSWER
Answer:
138°
Step-by-step explanation:
∠JAM = 180°
∠JAH = 42°
∠JAH + ∠HAM = 180° because they are supplementary
42° + ∠HAM = 180°
∠HAM = 180°-42°
∠HAM = 138°
Write the equation of a line that passes through the point (0, 3) and (-4, 11). *
Answer:
y = -2x + 3.
Step-by-step explanation:
The slope = (11-3)/(-4-0)
= 8/-4
= -2.
Using the point-slope form of a straight line:
y - y1 = m(x - x1)
Here m = -2 and (x1, y1) = (0,3). then
y - 3 = -2(x - 0)
y - 3 = -2x
y = -2x + 3.
