Answer:
Step-by-step explanation:
In order for Forest to decide how many cans of paint to buy he first needs to know how many square feet make up the wall that he wants to paint. He can calculate this by multiplying the length of the wall by the height of the wall. That will give him the square footage of the wall which can be represented as x in the following formula. Now that he has that, he needs to divide this value by 150 which is what each can of paint covers. The answer will be the number of cans that Forest should buy.
x / 150 = number of cans
The numbers of cans of paint he should buy can be calculated as follows :
x / 150.
where
x = Area of the wall needed to be painted in square feet.
Forest needs to paint the right side of his house because of sunlight and
rain.
According to his analysis each can of paint will cover an area of 150 ft².
This simply means for every 150 square feet of his wall, he will require 1
can of paint.
The number of paint he should buy can be determined as follows:
let
x = area of the right side of his wall needed to be painted
The number of can required = x / 150

Those are exponents.
Answer:
Both are equal to [tex]\frac{1}{16}[/tex]
Step-by-step explanation:
If the exponent is negative we can turn it into a fraction and make it positive.
This means the number goes to the denominator and the numerator becomes one. Therefore the following.
[tex]4^{-2} = \frac{1}{4^{2} } =\frac{1}{16}[/tex]
[tex]2^{-4} =\frac{1}{2^{4} } = \frac{1}{16}[/tex]

Given the side measurements, classify the triangle as acute, obtuse, right, or not a triangle. 8, 12, 14
Answer: It's an acute triangle.
Step-by-step explanation: I have the same problem, and I tried each choice, acute was the correct answer
The triangle with side lengths 8, 12, 14 is an obtuse triangle.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
To determine whether the triangle is acute, obtuse, or right, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides is equal to the square of the length of the longest side.
8² + 12² = 64 + 144 = 208
14² = 196
Since 208 is greater than 196, we can see that the triangle does not satisfy the Pythagorean theorem. Therefore, the triangle is not a right triangle.
Since the longest side is 14 and the sum of the squares of the two shorter sides is less than the square of the longest side, we can conclude that the triangle is obtuse.
Therefore, the triangle with side lengths 8, 12, 14 is an obtuse triangle.

how many solutions does x=-2 have
Answer:
One solution
Step-by-step explanation:
In a one- variable equation has infinitely many solutions when solving results in a true statement, such as 2=2
In a one- variable equation has one solution when solving results in one value for the variable, such as x = 5
In a one - variable equation has no solution when solving results in an untrue statement, such as 2=3
So, in this case the result x = -2 belongs to the 2nd sentence where it says one solution.

What is 11 divided by 5 as a fraction
11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number [tex]2\frac{1}{5}[/tex] .
What is 11 divided by 5 as a fraction?To convert the division of 11 by 5 into a fraction, we can express it as a ratio of two integers. Here's how we can derive the fraction:
When we divide 11 by 5, we get a quotient of 2 with a remainder of 1. So, we can write the division as:
11 ÷ 5 = 2 + 1/5
Since 2 is a whole number, we can express it as a fraction with a denominator of 1:
2 = 2/1
Now, we can rewrite the division using the same denominator:
11/5 = 2/1 + 1/5
To combine the fractions, we need a common denominator. The least common multiple (LCM) of 1 and 5 is 5. Therefore, we can multiply the fractions by appropriate values to make their denominators equal to 5:
11/5 = (2/1) × (5/5) + (1/5) = 10/5 + 1/5
Now that the denominators are the same, we can add the fractions:
11/5 = (10 + 1)/5 = 11/5
Therefore, the division of 11 by 5 can be expressed as the fraction 11/5.
The fraction 11/5 represents the result of dividing 11 into 5 equal parts. Each part would be equal to 11/5. It can also be simplified to a mixed number as 2 1/5, where the whole number part is 2 and the fractional part is 1/5.
So, 11 divided by 5 is equal to the fraction 11/5, which can also be expressed as the mixed number 2 1/5.

Explain how solving an equation with variables on both sides of the equation is different than solving an equation with a variable on only one side. Please use an example of each to show your work. You may use these examples or make up your own: 6x -9 = 15 16x - 20 = 44+ 5x show your work and explain your steps and why.
Answer:
See explanations below
Step-by-step explanation:
Given the equation
6x-9 = 15
Add 9 to both sides
6x-9+9 = 15+9
6x = 24
x = 24/6
x = 4
For the equation
16x - 20 = 44+ 5x
Since we have x variables on both sides, we will collect the like terms
16x - 5x = 44+20
11x = 64
Divide both sides by 11
11x/11 = 64/11
x = 64/11
x = 5.82
Hence the value of x is 5.82
Divide £84 in the ratio 5 : 2 *
Answer:
£60 : £24
Step-by-step explanation:
Let's put the ratio into one number.
5 + 2 = 7
There are 7 parts in our ratio, so let's find one part.
£84 ÷ 7 = £12
Going back to the original ratio, we can multiply one part by 5 and 2.
£12 × 5 = £60
£12 × 2 = £24
And it all adds back together to make £84.
£60 + £24 = £84

Step-by-step explanation:
_____________________145_____________________
Starting with number 145 it mentions that XY = 24 and XY:YZ = 1:2.
XY:YZ means ratio of XY over YZ so for each 1 XY there is 2 YZ.
Moving on and taking note that XY=24 so this means that,
[tex]\frac{XY}{YZ} =\frac{24}{YZ}= \frac{1}{2}[/tex]
Solving the above expression by cross multiplying 24x2 will give you YZ = 48. The same method applies to #146 and #148 the next questions.
_____________________146_____________________
YZ = 9 and XY:YZ=2:3
[tex]\frac{XY}{YZ} =\frac{XY}{9} =\frac{2}{3}[/tex]
XY= (2x9)/3 = 6
XY = 6
_____________________147_____________________
Given:
XZ = 2ft
YZ = 18in
In this question, you will have to refer to the proportion line given above the questions. It mentions that XZ = 2ft (which is the whole line) and YZ = 18in (which is from Y to Z). Take note that the units are not the same.
They're looking for XY which is the only unknown length in the given proportion line. To get XY you'll have to subtract XZ - YZ, but the units are not the same so you'll have to convert feet to inches since the answer options are given in inches.
Convert 2ft to inches:
To convert from feet to inches you'll have to multiply by 12 so 2x12 = 24.
Therefore, XZ = 24in
Now we subtract:
XZ - YZ = XY
24 - 18 = 6in
_____________________148_____________________
YZ = 1ft
XY: YZ = 1:4
YZ is given in feet and the answers are provided in inches so we'll have to convert.
1 x 12 = 12in
YZ = 12in
[tex]\frac{XY}{YZ} =\frac{XY}{12} =\frac{1}{4}[/tex]
XY = (1x12)/4 = 3in

Tom drives 200 miles in 4 hours, he drives the first 32 miles at an average speed of 64mph, work out his average speed for the rest of the journey.
Answer: Tom's average speed for the rest of the journey = 48mph
Step-by-step explanation:
Total distance driven = 200 miles
total time taken = 4hours
first 32 miles , he drove at an average speed of 64mph, To find the amount of time taken for the first 32 miles,
We Use the formulae
Speed = distance / time
Time = Distance / speed
=32/64 = 1/2 =0.5 hours
The remaining distance = Total distance covered - first 32 miles covered
= 200 -32= 168 miles
The remaining time for rest of journey = Total time taken - time covered in the first 32miles
4hours - 0.5 hours
=3.5 hours
Therefore Average speed for the rest of the journey = Distance for the remaining journey/ remaining time
168miles/ 3.5hours = 48mph
