Plz HELP PLZ HELP.The design for a new cardboard display is shown below. The designers want to determine how much cardboard they will need to build the display.
The total amount of cardboard the designers will need to build the display is
(blank) square feet.
9514 1404 393
Answer:
62 1/2 square feet
Step-by-step explanation:
The total area is the area of the central square plus the area of the four triangles.
The area formula for a square is ...
A = s² . . . . for side length s
The area formula for a triangle is ...
A = 1/2bh . . . . for base b and height h
Here, we have a square with side lengths of 5 m, and triangles with a base of 5 m and a height of 3 3/4 m. Then the area of the square plus the area of 4 triangles is ...
A = (5 ft)² + 4×(1/2)(5 ft)(3 3/4 ft) = 25 ft² +37 1/2 ft²
A = 62 1/2 ft²
62.5 square feet of cardboard will be needed to build the display.

Which term is not a like term?
3x
4y
7x
x
Answer:
4y is not a like term.
Step-by-step explanation:
Unlike the other variables, 4y has a y instead of an x. The numbers with an x variable can all be combined, but 4y can't be combined with an x variable.
The difference between the circumference and the radius of a circle is 111 cm. What is it
radius?
Answer:
I don't know follow the hint below i guess
Step-by-step explanation:
The circumference is pi x diameter. Double the radius to get the diameter.
Answer:
21 cm
Step-by-step explanation: Given
Circumference of a circle with radius (r)-radius (r)=111 cm
(2πr−r)=111
r(2π−1)=111
r(44/7−1)=111
r[(44/7−7)/7]=111
∴r=111×7/37=3×7=21cm
∴ radius is 21 cm.

Someone please help me find the volume
Answer:
317.3 units³
Step-by-step explanation:
Volume of the triangular pyramid = ⅓*Base area*height of pyramid
Height of pyramid = 17 units
Base area = ½*b*h = ½*8*14 = 56 unit²
Volume = ⅓*56*17 = 317.333333 ≈ 317.3 units³
Someone Help me please
help meeeeee plzzzzzz asap Find the area of the shaded regions.
Area of a circle is PI x r^2
The radius of the large circle is shown as 8 m
The diameter of A is the radius of the large circle which is 8 m so the radius would be 4 m
The radius of the small circle would be 2m
Area of large circle = pi x 8^2 = 64pi = 200.96 square m
Area of middle circle = pi x 4^2 = 16pi = 50.24 square m.
Area of small circle = pi x 2^2 = 4pi = 12.56 square m.
The area of the shaded region = large - middle + small
Area = 64pi - 16pi + 4pi = p2pi square m or 200.96 -50.24 + 12.56 = 163.28 square m.

Answer:
216 [tex]cm^{2}[/tex]
Step-by-step explanation:
The total area = the area of a square + the area of a circle
The area of the square = 11 x 11 = 121 [tex]cm^{2}[/tex]
The area of the circle = [tex]\pi[/tex]x[tex]\frac{11}{2}[/tex]x[tex]\frac{11}{2}[/tex] ≈ 95 [tex]cm^{2}[/tex]
Therefore, the total area = 121 + 95 = 216 [tex]cm^{2}[/tex]

Chelsea is filling a kiddie pool with water. For every
9
9
gallons of water she uses the pool fills
4
4
inches high.
If Chelsea wants to fill the pool to
15
15
inches, how many gallons of water will she use?
Chelsea will use
Answer:
33.75 gallons
Step-by-step explanation:
Determine how high the pool fills with one gallon
How high the pool fills with one gallon = 4/9 = 0.444444
The gallons needed to get the water to be 15 inches = 15 inches / 0.44 = 33.75 gallons

Which is a zero of x2 − 8 = 2x?
Answer:
The zeros are x=4, -2
Step-by-step explanation:
Its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.

y = 3x^2 - 4x
27 + y = 14x
Step-by-step explanation:
move the 27 to the other side of the equation like this
[tex]y = 14x - 27[/tex]
use this equation and substitute it into the y value of the first equation
Among 500 freshmen pursuing a business degree at a university, 311 are enrolled in an economics course, 243 are enrolled in a mathematics course, and 135 are enrolled in both an economics and a mathematics course. What is the probability that a freshman selected at random from this group is enrolled in each of the following?
a) an economics and/or a mathematics course.
b) exactly one of these two courses.
c) neither an economics course nor a mathematics course.
Solution :
Let A = Economics, B = Mathematics
n(A) = 311, n(B) = 243, [tex]$n(A \cap B) = 135$[/tex]
a). So, [tex]$n(A \cup B) = n(A) +n(B) - n(A \cap B)$[/tex]
= 311 + 243 - 135
= 419
b). n(A only) = 311 - 135
= 176
n(B only) = 243 - 135
= 108
Exactly one of these two courses
[tex]$=\frac{176+108}{500}$[/tex]
= 0.568
c). Neither economics nor mathematics
[tex]$=\frac{500-419}{500} $[/tex]
[tex]$=\frac{81}{500}$[/tex]
= 0.162

If x < 0 and y < 0, where is the point (x, y) located?
Answer:
Quadrant III
Step-by-step explanation:
Quadrant I -> (+x,+y)
Quadrant II -> (-x,+y)
Quadrant III -> (-x,-y)
Quadrant IV -> (+x,-y)
If x and y must both be less than 0, then they must both be negative. Therefore, Quadrant III is your answer.

Kathleen bought some glasses. She received a rebate of $50. Of her glasses cost $125, how much did she pay?
Answer:
You will pay $62.5 for a item with original price of $125 when discounted 50%. In this example, if you buy an item at $125 with 50% discount, you will pay 125 - 62.5 = 62.5 dollars.
Step-by-step explanation:
Misha and Dontavious were asked to solve the following problem using linear programming.
A local school district can operate a large bus for $300 per day and a small bus for $200 per day. The district needs to arrange transportation for at least 360 students for a field trip and has enough chaperones to have one chaperone per bus for up to 7 buses. Each large bus can hold 60 students and each small bus can hold 45 students. What is the minimum cost for the transportation for the field trip?
Misha decided the following represented this situation:
Let x = number of large buses
Let y = number of small buses
Objective Fx: C=300x+45y
Constraints:
200+60y≥360
x+y≤7
x≥0
y≥0
Dontavious decided the following represented this situation:
Let x = number of large buses
Let y = number of small buses
Objective Fx: C=300x+200y
Constraints:
60x+45y≥360
x+y≤7
x≥0
y≥0
Decide which student set up the correct Objective function and Constraints and using that information answer the following:
a) What are the vertices for the correct feasible region?
b) What is the minimum cost for transportation for the field trip and how did you arrive at this cost?
The correct function was: Dontavious
The constraints are the number of students at least 360 and the number of buses up to 7.
Dontavious wrote the appropriate inequalities. cost is $300 for large buses and $200 for small buses. and the constraints are the number of students per bus.
a) The feasible region is where the solution spaces overlap: this creates a small triangular area with the vertices at (6, 0), (7, 0) and (3, 4).
(6, 0), (7, 0), (3, 4)
b) 3 large buses and 4 small buses would cost 3*300 + 4*200 = $1700
6 large buses and 0 small buses would cost 6*300 = $1800 dollars
The cheapest solution would be 3 large buses and 4 small buses which would cost $1700
