Your school is installing new turf on the football field. A coordinate plane has been superimposed on a diagram of the football field where 1 unit = 20 feet. A) what is the length of the field. B) what is the perimeter of the field. C) Turf costs $2.69 per square foot. Your school has a $150,000 budget. Does the school have enough money to purchase new turf for the entire field? Please show the steps.
Answers
Answer:
Step-by-step explanation:
1) length of the field = 18 unit= 18*20=360 ft
2) circumference = 2(l+w)
2*(18*20+8*20)=1040
3) Area of the field = 18*8 units = 18*20*8*20ft^2 = 57600ft^2
Cost for the entire area= 57600*2.69= 170,000$
No it doesn't
A) The length of the field is 360 feet
B) The Perimeter of field is 1040 feet
C) The school does not have enough money to purchase new turf for the entire field.
what is Area of rectangle?The Area of rectangle is the product of the length to its width.
Area of rectangle= length x width
Given:
1 block= 20 feet
A) length= 18 blocks
= 18 x 20
= 360 feet
width= 8 blocks
= 8 x 20
= 160 feet
B) Perimeter of field
= 2( l+w)
=2( 360 + 160)
= 2 x 520
= 1040 feet
C) Area of field
= l x w
=360 x 160
= 57600 feet²
If cost of 1 square feet is $2.96
and, the cost of 57600 feet²
= 2.96 x 57600
= $170,496
No, the school does not have enough money to purchase new turf for the entire field.

The given percentage is [tex]62\frac{1}{2}[/tex] %
This fraction is in a mixed fraction.
Convert it into an improper fraction
So,
[tex]62\frac{1}{2}[/tex] % = (62x2 + 1)/2
= (124+1)/2
= 125/2 %
Now divide 125 by 2 to get the decimal form

5. Could the following triangles lie on the same
graphed line? Why or why not?
Answers
Answer:
Yes
Step-by-step explanation:
Because they are right triagnles
Answer: No, the triangles do not lie on the same graphed line
=========================================================
Explanation:
Your teacher is asking if the hypotenuse segments are parallel, that way one line can slide over to the other to be directly on top of it.
Recall that parallel lines have the same slope, and slope is rise over run.
rise = change in vertical distance = change in y
run = change in horizontal distance = change in x
Let's find the slope of the hypotenuse of the triangle on the left
slope = rise/run = 15/2 = 7.5
Let's do the same for the other triangle as well
slope = rise/run = 51/6 = 8.5
The slopes are different, so we don't have a perfect match. The hypotenuse segments do not lie on the same line.
Which equation describes the line with a slope of 2/5 and a y-intercept of 4.

Find the volume of the solid formed by rotating the region bounded by the given curves about the indicated axis. y = x3/4, x = 0, y = 1 (in the first quadrant); about the y-axis
Answers
The volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.
To find the volume of the solid formed by rotating the region bounded by the curves y = x³/4, x = 0, y = 1 in the first quadrant about the y-axis, we can use the method of cylindrical shells.
The formula for the volume using cylindrical shells is:
[tex]\mathrm V = \int\limits^a_b {2\pi \mathrm x \times \mathrm f(x)} \, dx[/tex]
Where:
a and b are the limits of integration (in this case, a = 0 and b = 1 since we are rotating in the first quadrant).
f(x) is the height of the shell at the given x-value.
2πx is the circumference of the shell at the given x-value.
In this case, we need to express y = x³/4 in terms of x to find the function f(x).
Given: y = x³/4
To find the function in terms of x, solve for x:
[tex]x = (4y)^{(1/3)[/tex]
Now, the function f(x) becomes:
[tex]\mathrm f(x) = (4x)^{(1/3)[/tex]
Now, let's calculate the volume using the cylindrical shell method:
[tex]\mathrm V = \int\limits^1_0 {2\pi \mathrm x \times \mathrm 4x^{1/3}} \, dx[/tex]
[tex]\mathrm V = 2\pi \int\limits^1_0 { x^{4/3}} \, dx[/tex]
To integrate, add 1 to the exponent and divide by the new exponent:
[tex]\mathrm V = 2\pi \times (3/7) \times x^{(7/3)} |^0_1[/tex]
Now, evaluate the expression at the limits of integration:
[tex]\mathrm V = 2\pi \times (3/7) \times (1)^{(7/3)} - 2\pi \times (3/7) \times (0)^{(7/3)[/tex]
[tex]\mathrm V = 2\pi \times (3/7) - 0[/tex]
[tex]\mathrm V = 6\pi/7[/tex]
So, the volume of the solid formed by rotating the region about the y-axis is 6π/7 cubic units.

To find x,equate EF to BC
2y+x=14( from here,it's impossible to calculate the values yet)
Find the value of ‹ACB
180°-(99+45)=36°
Now equate ‹DFE to 36° to find y
8y-5=36
8y=36+5
8y=41

Plug in the value of y to find x
2y+x=14

Answer:

FE = 14
m∠E = 36°
AB ≅ DF, BC ≅ FE, AC ≅ DE
∠D ≅ ∠A, ∠E ≅ ∠C, ∠F ≅ ∠B
Step-by-step explanation:
The expression involving y is that of an angle measure. In order to find y, we need to know the angle. So, it makes sense to start by identifying corresponding angles and their measures.
The congruence statement ΔABC ≅ ΔDFE means that ...
∠A ≅ ∠D . . . 45°
∠B ≅ ∠F . . . 99°
∠C ≅ ∠E . . . 180° -99° -45° = 36°
It also means ...
AB ≅ DF . . . 10
BC ≅ FE . . . 14
AC ≅ DE . . . unmarked (and unknown*)
__
Using the measure of angle F we can solve for y:
(8y -5)° = 99°
8y = 104 . . . . . . divide by ° and add 5
y = 13 . . . . . . . . divide by 8
Using the length of side FE, we can solve for x:
2y +x = 14
2·13 +x = 14 . . . . substitute for y
x = 14 -26 . . . . . .subtract 26
x = -12

* The length of the unmarked side is unknown because its measure will depend on how you compute it. The given angles and side lengths are inconsistent, so the figure shown cannot exist. If angle measures are taken as accurate, the side measures are not, and vice versa.

Answer:
30, or 42
Step-by-step explanation:
If they took 12 quizzes over the course of 2 weeks, then we can assume that they take 6 quizzes each week (12/2 = 6).
Over the course of 5 weeks, they'll have taken 30 quizzes if the above is true. However, the 'or' is there because I don't know if they're including the past 12 or not. If they are including the 12 quizzes taken over 2 weeks, then the answer is 42. If they are only referring to the 5 weeks of school, then the answer is 30.
