i dont know if this is correct or not but here you go!
Help . i need the answer quicckkkkkkk
Answer:
Simplifying
an = 8n + -7
Reorder the terms:
an = -7 + 8n
Solving
an = -7 + 8n
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by 'n'.
a = -7n-1 + 8
Simplifying
a = -7n-1 + 8
Reorder the terms:
a = 8 + -7n-1

What is 4x+6<22 ? I fleet getting incorrect answers
Answer:
The answer is x < 4
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex]4x < 22 - 6[/tex]
2) Simplify 22 - 6 to 16.
[tex]4x < 16[/tex]
3) Divide both sides by 4.
[tex]x < \frac{16}{4} [/tex]
4) Simplify 16/4 to 4.
[tex]x < 4[/tex]
Therefor, the answer is x < 4.
Find the surface area of a square pyramid with side length 6 mi and slant height 7 mi.
Answer:
total surface area (TSA) = [tex]2bs[/tex] + [tex]b^{2}[/tex]
length = 6 mi
slant height = 7 mi
∴ TSA = 2 × 6 × 7 + [tex]6^{2}[/tex]
= 84 + 36
= 120
The surface area of the square pyramid is 120 sq. mi.
Given:
side length (s) = 6 mi
slant height (l) = 7 mi
*image of a typical square pyramid is shown in the attachment below.
Recall:
Formula for surface area of square pyramid (SA) = [tex]A + \frac{1}{2} Pl[/tex]
Where,
[tex]A =[/tex] area of the base = [tex]s^2 = 6^2 = 36[/tex] sq mi
[tex]P =[/tex] perimeter of the base = [tex]4(s) = 4\times 6 = 24[/tex] mi
[tex]l =[/tex] slant height = 7 mi
Plug in the values
[tex]SA = 36 + \frac{1}{2}\times 24\times 7\\SA = 36 +84\\SA = 120[/tex]
The surface area(SA) of the square pyramid is 120 sq. mi

Answer: B. (2,1)
Step-by-step explanation:
its not c because if you look at R you see that it is going 4,3 not 3,4 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then the x-axis.
It's not D because if you look at Q you see that it is going 3,5 not 5,3 because when you doing ratios on a number line it goes x-axis then y-axis next not y-axis then x-axis.

Country Financial, a financial services company, uses surveys of adults age 18 and older to determine if personal financial fitness is changing over time (USA Today, April 4, 2012). In February of 2012, a sample of 1000 adults showed 410 indicating that their financial security was more than fair. In February of 2010, a sample of 900 adults showed 315 indicating that their financial security was more than fair. a. State the hypotheses that can be used to test for a significant difference between the population proportions for the two years. H : Pi - P2 - Select your answer HA : P1 P2 - Select your answer - b. What is the sample proportion indicating that their financial security was more than fair in 2012? Round your answer to two decimal places. In 2010?
Answer:
H0 : p1 - p2 = 0
H1 : p1 - p2 ≠ 0
Phat 2010 = 0.35
Phat 2012 = 0.41
Step-by-step explanation:
The null and alternative hypothesis :
H0 : p1 - p2 = 0
H1 : p1 - p2 ≠ 0
The null means there is no difference in proportion for the two years while the alternative claims that there is difference in proportion for the two years.
Sample proportion for 2010:
Phat = x / n
x = 315 ; n = 900
Phat = 315 / 900
Phat = 0.35
Sample proportion for 2012 :
Phat = x / n
x = 410 ; n = 1000
Phat = 410 / 1000
Phat = 0.41
find the surface area of the figure below
Answer:
64
Step-by-step explanation:
square= 16
triangle= 12
12*4 = 48+16 = 64
Answer:
64 m²
Step-by-step explanation:
Hello There!
The surface area is the total area of the figure
So in order to find the area we need to find the area of each shape
For the square:
the square has a length of 4 so we can simply find the area by squaring it
4 * 4 = 16
so the area of the square is 16 square meters
Now we need to find the area of the triangles
The formula for area of a triangle is
[tex]A=\frac{bh}{2}[/tex]
where b = base and h = height
The triangles dimensions are:
base - 4m
height - 6m
having found these dimensions we plug them in into the formula
[tex]A=\frac{4*6}{2} \\4*6=24\\\frac{24}{2} =12[/tex]
so the area of one of the triangles is 12 square meters
We want to find the total area of all of the triangles
To do so we multiply the area of one triangle by 4 (because there are four triangles)
12 * 4 = 48
So the total area of the four triangles is 48 square meters
Finally we add the two areas
48 + 16 = 64
so we can conclude that the total surface area of the pyramid is 64 m²

Answer:
21
Step-by-step explanation:
I haven't done this in a long time but this is what I know: the discount would overall be 25%. So, you set it up by .25(84) = 21. Therefore the jacket would cost $21.
