Answer:
x=-3
Step-by-step explanation:
First you must distribute -5 to 2x and -7
so you get
-10x+35+24=89
then you will subtract 35 from both sides and get
-10x+24=54 then you will subtract 24 from each side and get
-10x=30 then you will divide -10 and get
x=-3

A triangular prism and two nets are shown:
A right triangular prism is shown with two nets. The triangular base of the prism has height 5 inches, base 12 inches, and hypotenuse 13 inches. The length of the prism is 15 inches. Net A has 3 rectangles having dimensions 5 by 15, 15 by 12, and 15 by 13, and two triangles having legs 5 inches and 12 inches. Net B has 3 rectangles having dimensions 5 by 13, 13 by 12, and 13 by 15, and two triangles having legs 5 inches and 12 inches.
Which is the correct net of the prism and what is the surface area of the prism?
Net B with 420 square inches
Net B with 500 square inches
Net A with 510 square inches
Net A with 450 square inches
Answer:
Net for the prism will have 3 rectangles with dimensions 5 by 15, 12 by 15 , and 13 by 15, and 2 triangles with legs 5 inches and 12 inches.
The correct net is net a.
Surface area = sum of areas of the three rectangles and sum of the two triangles.
SA = (5 x 15) + (12 x 15) + (13 x 15) + (5 x 12) = 75 + 180 + 195 + 60 = 510 square inches.

Given:
The graph of a function [tex]y=h(x)[/tex].
To find:
The interval where [tex]h(x)>0[/tex].
Solution:
From the given graph graph it is clear that, the function before x=0 and after x=3.6 lies above the x-axis. So, [tex]h(x)>0[/tex] for [tex]x<0[/tex] and [tex]x>3.6[/tex].
The function between x=0 and x=3.6 lies below the x-axis. So, [tex]h(x)<0[/tex] for [tex]0<x<3.6[/tex].
Now,
For [tex]-1<x<0[/tex], the graph of h(x) is above the x-axis. So, [tex]h(x)>0[/tex].
For [tex]0<x<1[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].
For [tex]1<x<2[/tex], the graph of h(x) is below the x-axis. So, [tex]h(x)<0[/tex].
Only for the interval [tex]-1<x<0[/tex], we get [tex]h(x)>0[/tex].
Therefore, the correct option is A.

Answer:
3 tons, 1110 pounds
Step-by-step explanation:
A Ton weighs 2000 pounds, first convert the 4 tons.
You can solve this by multiplying 4 times 2000, and you will get 8000.
Now Add 8000 to 422, and your solution: 8422.
Now subtract 8422 by 1312, and you will get 7110.
Now convert this back to tons, start thinking, how many times can 2000 go into 7110.
That would be 3 my good sir.
Your Remainder: 1110 Pounds
Your Answer: 2 Tons, And 1110 Pounds.

Jon is drawing a quadrilateral.
The length of each side is 5.2cm to 1 decimal place.
Complete the error interval for the length of one side.
And Complete the error interval for the perimeter.
Please help with this one urgently.
Answer:
We know that the measure of each side is:
5.2cm to 1 decimal place.
Then we can assume that the error is 0.05cm (half of the second decimal place).
With this, the interval of the length of each side will be:
(5.2cm - 0.05cm) = 5.15cm (as the minimum)
(5.2cm + 0.05cm) = 5.25cm (as the maximum)
Then the interval is (5.15cm, 5.25cm)
2) We know that the perimeter of a square of sidelength L is:
P = 4*L
In this case, the minimum perimeter will be if we choose the smallest sidelength, this is:
P = 4*5.15cm = 20.6cm
And the maximum perimeter can be:
P = 4*5.25cm = 21cm
Then the interval is: (20.6cm, 21cm)
Here we can see that the error for the perimeter is 0.2cm, which is equal to 4 times the error of the length of a side (0.05cm) , as expected.
Find the area and the perimeter of a rectangle with sides 4 1/5 in, and 4 2/7 in.

Step-by-step explanation:
A business developer would like to purchase an abandoned corner lot in a small town and build a small convenience store with gasoline pumps on the site. Town leaders are concerned about potential traffic and noise impact to the adjacent neighborhood and send printed surveys to 500 homes in the affected area. Of the 123 surveys returned, 87% oppose the plan to develop the corner lot. How could the sampling design cause town leaders to overestimate or underestimate overall support of the development plan?
(A) The leaders may underestimate support because only 123 surveys were returned.
(B)The leaders may overestimate overall support because many residents who did not receive surveys will support the plan.
(C)The leaders may underestimate overall support because many residents who support the plan may be less likely to respond.
(D)The leaders may underestimate support because it can be assumed that all residents who did not return the surveys would support the plan.
Answer:
C
Step-by-step explanation:
Just took the test.

Answer: 60,10
Step-by-step explanation: hope this helps
Answer:
y=6x
Step-by-step explanation:
y=kx
find k, which is constant
y=60, x= 10

Solve using Y=Mx+b
M=-5 and (-3,-2)
Given:
M=-5 and (-3,-2).
To find:
The equation in the form [tex]y=mx+b[/tex].
Solution:
The slope intercept form of a line is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
We have m=-5. Putting m=-5 in (i), we get
[tex]y=-5x+b[/tex] ...(ii)
We have a point (-3,-2). Putting x=-3 and y=-2 in (ii), we get
[tex]-2=-5(-3)+b[/tex]
[tex]-2=15+b[/tex]
[tex]-2-15=b[/tex]
[tex]-17=b[/tex]
So, the value of b is -17.
Putting b=-17 in (ii), we get
[tex]y=-5x+(-17)[/tex]
[tex]y=-5x-17[/tex]
Therefore, the required equation is [tex]y=-5x-17[/tex].

In ΔABC, c = 630 inches, ∠C=165° and ∠A=11°. Find the length of a, to the nearest inch.
Answer:
464
Step-by-step explanation:
Find other angle:
<B = 180 - 165 - 11 = 4
Then plug in (opposite sides go together):
[tex]\frac{a}{sin 11}[/tex] = [tex]\frac{630}{sin 165}[/tex]
[tex]a = \frac{630 sin 11}{sin 165} = 464.454 = 464[/tex]
The length of side a in ΔABC is 460 inches.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know the sine rule of ΔABC which is a/sinA = b/sinB = c/sinC.
Given, In ΔABC, c = 630 inches, ∠C=165° and ∠A=11°.
∴ a/sinA = c/sinC.
a/sin11° = c/sin165°.
a/0.19 = 630/0.26.
a = (630×0.19)/0.26.
a = 460.
