GUYSS I neeed HELP ON THIS MATH QUESTION!!!!!!!!! The question is "If you want to know how many boxes of markers will fit in a drawer, do you need to know the length, area, or volume of the drawer?" GUYSSS HELP!!! I really NEED HELP ON THIS I'm giving out 50 POINTS!!!!
Answer:
You will need to know the volume of the drawer
Step-by-step explanation:
Why? Because volume is the entire inside of a shape. The area is only for one side. And length, well... It's useless when you don't know the height or width to find room for a marker.

The value of 3(y+5) will be 75.
First, We need to solve the given linear equation y - 16 = 4 to find the value of y :
⇒ y-16=4
taking -16 to right side of the equation,
⇒y=4+16
⇒y=20
Now, we can put the value of Y in the 2nd equation 3(y+5):
⇒ 3(y+5)
multiply both the terms inside brackets from 3,
⇒ 3y + (3x5)
⇒3y + 15
now, put calculated value of y in the equation,
⇒3x20 + 15
⇒60 + 15
⇒75
∴ 3(y+5) = 75

Answer: Z=14
Step-by-step explanation:
Simplify the equation: 1/4z=7/2
then multiple both sides by 4:
4 (1/4) = 4 (7/2)
z= 14
Answer: z=14
Step-by-step explanation: very easy
1/4z = 3 1/2 Divide each side by 1/4 to isolate z
3 1/2 will be divided by 1/4
How to divide 3 1/2 by 1/4?
Keep, change, flip.
First: Convert 3 1/2 to an improper fraction which is 7/2
Second: 7/2 / 1/4 keep 7/2
7/2 x 1/4 change from dividing to multiplying
7/2 x 4/1 flip 1/4 around to make it 4/1
28/2 multiply and then simplify to 14.
so the answer is 14

1. In 2014, the attendance at Jefferson School's Fall Festival was 650. In 2015, the attendance was 575. What was the percent change in attendance from 2014 to 2015? Round to the nearest whole percent.
Answer:
11%
Step-by-step explanation:
First you need to find the difference between 575 and 650. That's 75 people. 75 is around 11% of 650, so 11% is the rounded whole percent.
Answer:
11.5
Step-by-step explanation:
650-575 = 75
11.54 = 75 out of 650

PLEASE HELP THIS IS ON A TEST AND I DON'T PAY ATTENTION Paul received an estimate of $75,000 for an inground pool. After the job was completed, it cost him $93,000. Express the error in this estimate as a percentage.
A.24% error
B.19% error
C.81% error
D.33.3% error
Answer:24% error
Step-by-step explanation:
subtract the estimate and the cost
93,000-75,000
=18000
divide the cost and the subtracted sum you just got
=[tex]\frac{18000}{75000}[/tex]
cross out the common factor
=[tex]\frac{6}{25}[/tex]
Multiply a number to both the numerator and denominator (easier if you multiply the number that makes the denominator 100)
[tex]\frac{6}{25} x\frac{4}{4}[/tex]
=[tex]\frac{24}{100}[/tex]
write the fraction as a percentage
=24%

( thank you for the help <3 this one is confusing me, i been trying but I’m confused )
Answer:
ok so I'm not gonna do em but I will explain how to find mean, median, mode and range
Step-by-step explanation:
starting of with mean: first you add all your numbers ex your first question: 61+98+60+60+57+81+93=510
secondly you devide the sum of all those values by how many values there are. there are 7 values so you would devide 510 by 7 ex: 510÷7= 72.9 (rounded by nearest hundredth)
finding the median: firstly you order all your values from least to greatest :ex w your first question again: 61,98,60,60,57,81,93 ~ 57,60,60,61,81,93,98
secondly you find the middle number of what is in those values by deviding it into 2 and seeing what the middle would be. ex: 57,60,60, ⁶¹,81,93,98 our median is 61.
in the case there is 2 numbers in the middle ex number 10:23,30,35,52,55,55 ~ 23,30,³⁵,⁵²,55,55 you add those 2 middle values and devid by 2 basically find the mean ex: 35+53÷2= 61.5 that's your mean.
finding range: subtract lowest from highest value ex question 1: 98-57=41 your range is 41.
finding mode:Place all numbers in a given set in order; this can be from lowest to highest or highest to lowest, and then count how many times each number appears in the set. The one that appears the most is the mode.ex: 57,60,60,61,81,93,98 60 appears the most so it is the mode.
hope this helps I spent like 45 mins writing this
Answer:
1. Mean: 72.857 Median: 61 Mode: 60 Range: 41
2. Mean: 71.5 Median: 75.5 Mode: 94 Range: 76
3. Mean: 69 Median: 73 Mode: no mode Range: 36
4. Mean: 62.667 Median: 68.5 Mode: 31 Range: 66
5. Mean: 53.833 Median: 68.5 Mode: 13 Range: 72
6. Mean: 58 Median: 74 Mode: 22 Range: 71
7. Mean: 51 Median: 55 Mode: 55 Range: 68
8. Mean: 50.182 Median: 58 Mode: 11, 73 Range: 83
9. Mean: 43.714 Median: 45 Mode: 12 Range: 77
10. Mean: 41.667 Median: 43.5 Mode: 55 Range: 32
Step-by-step explanation:
How to find Mean: Add all the numbers together then divide by the number of numbers.
How to find Median: Place the numbers in value order and find the middle.
If odd, cross out the leftmost number, then the rightmost number, and then repeat. When you have one number left, this is your median.
If even, cross out numbers on either side, but you should have two numbers exactly in the middle. Add them together and divide by two for the median value.
How to find Mode:
Put the numbers in order, then count how many of each number. A number that appears most often is the mode.
How to find Range:
Order all values in your data set from low to high, then subtract the lowest value from the highest value.
i hope this helps!

Step-by-step explanation:
You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
Part A: Which equation can you use to solve for x , your normal hourly rate?
Part B: What is your normal hourly rate?
Equation that represents the given situation is 40x + 6 *1.5x = 612.50.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given, You are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. You worked 46 hours this week and earned $612.50.
First, define the variables. Let’s let x = his regular pay.
For first 40 hours pay = 40x
Over time pay = 1.5x
Since he worked 46 hours
Thus his over time pay = (46 -40) *1..5x
Thus his over time pay = 6 * 1.5x
Since, You worked 46 hours this week and earned $612.50.
linear equation that represents the given situation
40x + 6 *1.5x = 612.50
Normally hourly rate:
40x + 9x = 612.50
49x = 612.50
x =12.5
Therefore, Equation that represents the given situation is 40x + 6 *1.5x = 612.50.
