7) Find the value of x if the surface are is 216ft
Answer:
6 ft (not squared)
Step-by-step explanation:
SA = 6(6)(2) + 4(6)(x)
216 = 72 + 24x
144 = 24x
x = 6

which of the following ordered pairs is a solution of the equation -2y + 9 = -x? A.(2,5) B.(-3,15) C.(4,-1)
Answer:
Step-by-step explanation:
-2y + 9 = -x
x - 2y = -9
Plug in each set of points and see if the equation holds true.
A. 2 - 2(5) = ?
B. -3 - 2(15) = ?
C. 4 - 2(-1) = ?
I don't think that any of them work.

3) 180 - 86 = 94
Consider an angle with a measure of θ=225∘.
Sketch a diagram representing the situation.
Determine the measure of the reference angle for this angle.
_______°
Now, determine the exact values of the following expressions. Your answers should include fractions and square roots, and not decimal values.
cos(θ)=
sin(θ)=
tan(θ)=
Answer:
cos 225° = [tex]-\frac{\sqrt{2} }{2}[/tex]
sin 225° = [tex]-\frac{\sqrt{2} }{2}[/tex]
tan 225° = 1
Step-by-step explanation:
I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45° (225 - 180 = 45)
cos and sin are negative in the 3rd quadrant and the tan is positive
cos 225° = - cos 45° = [tex]-\frac{\sqrt{2} }{2}[/tex]
sin 225° = -sin 45° = [tex]-\frac{\sqrt{2} }{2}[/tex]
tan 225° = tan 45° = 1
work out the size of angle x 101 degrees and 38 degrees
Answer:
the inside angle beside 101 is 180-101 = 79 degrees.
the angle beside x = 180-(79+38).
that is 63 degrees.
therefore the angle x = 180-63 that's
117 degrees

Zach bought a video game that was 30% off. He paid $40 for the video game. How much was the game ORIGINALLY? (40 is the AMOUNT PAID so what Percent was me use to match that PART?)
Answer:
57.14$
Step-by-step explanation:
70/100 ( Remember 30% off so only paid 70% of original price) = 40/x ( 40$ is the price paid, x is the unknown original price)
70 = 40
100 X
40×100 = 4,000
4,000÷ 70X = 57.14
In 1960 sociologists studied a random sample of 1,018 families that consisted of a husband, a wife, and at least one child. Of those families, 5.8 percent reported that the wife was the primary wage earner of the family. In 2011 the study was replicated with a random sample of 1,013 families that consisted of a husband, a wife, and at least one child. Of those families, 22.3 percent reported that the wife was the primary wage earner of the family. Which of the following represents a 99 percent confidence interval for the difference between the proportions of families that consisted of a husband, a wife, and at least one child from 1960 to 2011 that would have reported the wife as the primary wage carner? (0.223)(0.777) (0.058) (0.942)
(A) (0.223-0.058) 1.96L03 ) (223-0058) ±196 1.013 1 1.018
(B) (0.223-0058) 226(07,(0580942 1,013 1,018
(C) (0.223-0058)2.576, (02230772)(0.45810942 (0.058)(0.942) 1,018
(D) (0.223-0.058) t2.326, 2,031 1,013 1.018
(E) (0.223-0058)?2.57612031(1.013 +1.18
Answer:
(0.223 - 0.058) ± 2.576 * sqrt[((0.223)(0.777))/1018 - ((0.058)(0.942))/1013]
Step-by-step explanation:
Given that :
P1 = 22.3% = 0.223
q1 = 1 - P1 = 1 - 0.223 = 0.777
Sample size, n1 = 1018
P2 = 5.8% = 0.058
q2 = 1 - P2 = 1 - 0.058 = 0.942
Sample size, n2 = 1013
Confidence level, Zcritical at 99% = 2.576
Using the relation :
(P1 - P2) ± Zcritical * Sqrt[(P1q1/n1 + P2q2/n2)
(0.223 - 0.058) ± 2.58 * sqrt[((0.223)(0.777))/1018 - ((0.058)(0.942))/1013]

A bookstore had 60 copies of a magazine. Yesterday, it sold 1/4 of them. Today, it sold 2/3 of what remained. How many copies does the bookstore have left?
Answer:
15
Step-by-step explanation:
60×1÷4=15(1/4)
60-15=45
45×2÷3=30(2/3)
45-30=15

Hello There!
The shown figure is a 6 sided figure and if you didn't know the interior angles of a 6 sided figure add up to equal 720
so
720=110+8x-1+5x+36+116+7x+19+6x-2
now we solve for x
step 1 combine like terms
110-1+36+116+19-2=278
8x+5x+7x+6x=26x
now we have
720=278+26x
step 2 subtract 278 from each side
720-278=442
we now have
442=26x
step 3 divide each side by 26
442/26=17
we're left with
x=17
