The perimeter of a playing field for a certain sport is 334ft. The field is a rectangle, and the length is 47 ft longer than the width. Find the dimensions.
Answer:
The dimensions of the rectangle = 60ft by 107ft
Where 60 ft = Width of the playing field
107ft = Length of the playing field
Step-by-step explanation:
A playing field is Rectangular is shape, hence,
The formula for Perimeter of a rectangle = 2(L + W)
P = 334 ft
L = 47 + W
W = W
Hence we input these values in the formula and we have:
334 = 2(47 + W + W)
334 = 2(47 + 2W)
334 = 94 + 4W
334 - 94 = 4W
240 = 4W
W = 240/4
W = 60
There fore, the width of this playing field = 60 ft
The length of this rectangle is calculated as:
47 + W
47 + 60
= 107 ft
The length of this playing field = 107ft
Therefore the dimensions of the rectangle = 60ft by 107ft

Last year, Kenia got a 350 on her 6th Grade Math EOG. This year Kenia earned a 399, which was a high enough score to make a Level 4. What was the percent of increase in Kenia's score?
Answer:
14%
Step-by-step explanation:
Last year's score = 350
This year's score = 399
What was the percent of increase in Kenia's score
Percentage increase= (new score - old score) / old score × 100
= (399-350) / 350 × 100
= 49 / 350 × 100
= 0.14 × 100
= 14%
The percent of increase in Kenia's score is 14%
What is the value of x in the equation −x = 3 − 4x + 15?
Answer:
x = 6
Step-by-step explanation:
First of all you should collect like terms
-x = 18 - 4x
Then you should move the variable to the left
-x + 4x = 18
After that you should collect like terms
3x = 18
Finally divide both sides by 3
x = 6

Answer:
Mrs. Davis package is 30 ounces
Step-by-step explanation:
x for ounces
mailbox plus=0.25x+5
united package=0.35x+2
since Mrs.Davis noticed that she is going to pay same price then:
0.25x+5=0.35x+2
5-2=0.35x-0.25x
3=0.10x
x=3/0.10
x=30 ounces
Mrs. Davis package is 30 ounces
check:
0.25x+5=0.25(30)+5= 12.5 dollars
o.35(30)+2=12.5 dollars

Given: {(−2, 3), (−1, 2), (0, 2), (−2, 9)}. Is this relation a function? Explain.
Answer:
No
Step-by-step explanation:
(-1,2) and (0,2) have the same y value. Functions cannot share the same y value
The relationships represents by {(−2, 3), (−1, 2), (0, 2), (−2, 9)} is not function.
Given that, {(−2, 3), (−1, 2), (0, 2), (−2, 9)}. Is this relation a function is to be specified.
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
In the relation {(−2, 3), (−1, 2), (0, 2), (−2, 9)}
(−2, 3), (−2, 9) are two pairs that show two images of one pre-image that why it is not a function.
Thus, the relationships represents by {(−2, 3), (−1, 2), (0, 2), (−2, 9)} is not function.

Marcus is skiing. He is 869 1/10 get up the mountain. He descends to 450 7/10 feet. What is his change in elevation
Answer:
418 4/10
Step-by-step explanation:
To answer this we subtract 450 7/10 from 869 1/10.
We must borrow a '1' from 869 1/10: 868 11/10
Now subtract 450 7/10 from 868 11/10:
418 4/10 (CHANGE IN ELEVATION)
This reduces to 418 2/5.

Answer the following questions about this figure.
PLS HELP ME
Answer:
143
Step-by-step explanation:
First, figure out the measurement of angle 2. Take 180 degrees (the total of the triangle) and subtract 90 (the right angle) and 53 (the given measurement of angle 1). 180-90-53=37
Angle 2 measures 37 degrees. The measurements of angles 2 and 3 need to equal 180 when added together as they form a straight line, so take the total (180) and subtract the value of angle 2 (37). 180-37=143
Angle 3 measures 143 degrees
