One week, Paige earned $165.75 at her job when she worked for 13 hours. If she is paid the same hourly wage, how many hours would she have to work the next week to earn $318.75?
Answer: 25 hours
Step-by-step explanation:
From the question, we are informed that Paige earned $165.75 at her job when she worked for 13 hours. This means that her hourly rate will be:
= $165.75 / 13
= $12.75.
The number of hours that she would have to work the next week to earn $318.75 will be:
= $318.75 / $12.75
= 25 hours

Answer:
Step-by-step explanation:
Here you go mate
Step 1
2n=n+3 Equation/Question
Step 2
2n=n+3 Simplify
2n=n+3
Step 3
2n=n+3 Subtract n
answer
n=3
The value of n is given by the equation n = 3
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
2n = n + 3 be equation (1)
On simplifying the equation , we get
Subtracting n on both sides of the equation , we get
2n - n = 3
n = 3
Therefore , the value of n is 3
Hence , the equation is n = 3

Answer: 4
Step-by-step explanation:
Answer:
PZ = 4
because P is the centre of XYWZ
=> PZ = 1/2.XZ
WP = 1/2. WY
=> PZ + WP = 1/2.(XZ + WY) = 1/2.24 = 12
=> PZ = 12 - WP = 12 - 8 = 4

Three times a day, Dylan mixes 2 ounces of protein powder into a shake. How many days can he make all three shakes from his 5-pound container of protein powder? Remember, there are 16 ounces in a pound. Enter your answer in the box.
Answer:
13 days
Step-by-step explanation:
To calculate this we first need to find the total number of ounces in the container. We do this by multiplying the total number of pounds in the container by 16oz
5 * 16oz = 80oz
Since Dylan is making three 2oz shakes per day that would mean he is using a total of 6oz (2oz*3) per day. Therefore, in order to find out how many days the container will last we simply divide the total amount of protein powder in the container by the amount he uses every day.
80oz / 6oz = 13.33 days
The container will last 13.33 days but since we cannot count a percentage of a day, then we need to round down to the day in which he will no longer be able to make the three shakes which are 13 days.
Answer:
13

On the left triangle, the shorter side is labeled 4 inches and the longer side is labeled 10 inches. On the right triangle, the shorter side is labeled x inches and the longer side is labeled 20 inches.
The two triangles above are similar. Find the value of x. Be sure to explain your steps.
Answer:
8
Step-by-step explanation:
We are dealing with similaraty and similar shapes length are in proportion so we are going to set up an proportion.
Length of left triangle small side/ Length of left triangle long side= length of right triangle small side/length of right triangle long side
4/10=x/20
Cross multiply: 10x=80
x=8
Answer:
x = 8 inchesStep-by-step explanation:
As the triangles are similar, their corresponding sides will have same ratio:
left short side /right short side = left long side / right long sideor simpler
s₁/s₂ = l₁/l₂Substitute values to find the missing one:
4/x = 10/204/x = 1/2x = 4*2x = 8The missing side is 8 inches long

The internal measures of a cuboidal room are 9m, 5m and 6m respectively. Find the total cost of
whitewashing all four walls of a room, if the cost of white washing is ₹ 5 per sq.m. What will be the cost of white washing if the ceiling of the room is also whitewashed.
Answer:
₹ 1290Step-by-step explanation:
The total surface area of the room = 2(LW + WH + LH)
TSA = 2(9*5 + 9*6 + 5*6)
TSA = 2(45 + 54 + 30)
TSA = 2(129)
TSA = 258
Hence the total surface area of the room is 258m²
If 1m² = ₹ 5
258m² = 5(258) = ₹ 1290
The cost of white washing if the ceiling of the room is also whitewashed is ₹ 1290
