180$ simple unless u have a different way to do it
Answer:
y=15x+25, the cost is 205 dollars
Step-by-step explanation:
The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.

Find the area of the figure in the image attached. Round to the nearest tenth if necessary.
Answers
Answer: 15in^2
Step-by-step explanation:
first you need to find the area of the rectangle, so you would multiply 7 and 3, which gives you 21, (A=L•W). So now you need to find the area of the triangles, the formula for that is A= 1/2 b•h, so you get 3in for the area of the triangle, but since there are two and they are the exact same triangle you would just combine them, so the area for both triangles is 6in, so then you would need to subtract the 6 from the 21 so that you can find the area of the shape, and your final answer would be 15in(squared). hopefully you understand

Answer:
This is a rectangle, so if AB is equal to 3 centimeters, then DC is equal to 3 centimeters.
Since Angle X is equal to 45 degrees, then angle CDE, is also equal to 45 degrees, and we have an isosceles triangle, since angle CDE and DEC are equal to each other.
This means, that CE = DC.
And because E is the midpoint of CB, CE = EB.
So basically, we have:
DC = CE = BE
DC = 3
3 = CE = BE
And we see that CE and BE are both equal to 3, which makes CB equal to 6, which makes solving the area easy. (3 x 6), which is 18.

find the surface area of the composite figure - image attached,, need answer now!!
Answers
Answer:
Surface Area = 392 cm²
Step-by-step explanation:
Green (front):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Green (left side):
SA = bh
= 5 (10)
= 50 cm²
Green (right side):
SA = bh
= 5 (10)
= 50 cm²
Green (back):
SA = 1/2bh
= 1/2 (12) (8)
= 48 cm²
Blue (front):
SA = bh
= 12 (4)
= 48 cm²
Blue (left side):
SA = cm²
= 5 (4)
= 20 cm²
Blue (right side):
SA = bh
= 5 (4)
= 20 cm²
Blue (back):
SA = bh
= 12 (4)
= 48 cm²
Blue (bottom):
SA = bh
= 12 (5)
= 60 cm²
Total:
48 + 50 + 50 + 48 + 48 + 20 + 20 + 48 + 60 = 392 cm²
Using the GCF and distributive property, which expressions is equivalent (equal) to 12y + 16

C 28y
D 16 + 12y
Answers
Answer:
4(3y+4)
Step-by-step explanation:
12y + 16
4*3*y +4*4
Factor out 4
4(3y+4)
Answer:
2(6y+80) = 12y+160
4(3y+4) = 12y+16
28y = 28y
16+12y = 12y+16 (did not use distributive property)
So, B is correct.

Since the 2nd stage light is above P, then its x-coordinate is also the same as that of P, which is 4. We know that there are 2 units per grid and since the 2nd stage is 8 units above P, the conversion to the number of grids is
[tex]8\:\text{units}×\dfrac{1\:\text{grid}}{2\:\text{units}} = 4\:\text{grids}[/tex]

1/9 or 3^-2
Step-by-step explanation:
Ignore the value of 1/3 for now and just focus on the 3^2.
Find 3^2:
3*3 = 9
Now 9 is the denominator, therefore our answer would be 1/9 once you reassemble the fraction.
Because 1/9 is our new fraction, we can use a negative exponent to create the same result. This is because the negative exponent rule tells us that a number with a negative exponent should be put to the denominator. Therefore we can then use 3^-2.

3^-2

find three consecutive integers for which 3 times the sum of the first and third integers is -342? show step by step
Answers
Answer: The integers are -58, -57, -56.
Step-by-step explanation:
The difference between two consecutive integers is 1.
If you let the smallest of the three consecutive integers equal x, then the next greater one is x + 1, and the greatest of the three is x + 2.
Integers: x, x + 1, x + 2
The sum of the first and third is: x + x + 2
3 times the sum of the first and third is: 3(x + x + 2)
That product equals -342.
3(x + x + 2) = -342
3(2x + 2) = -342
Divide both sides by 3.
2x + 2 = -114
Subtract 2 from both sides.
2x = -116
Divide both sides by 2.
x = -58
x + 1 = -57
x + 2 = -56
The integers are -58, -57, -56.

Answers
Answer:
Let the height of the larger box = h
and length and width of the larger box = l and w , repectively
Now , Let find the volume of the larger box
Volume = length * width * height
So Volume of the larger box = l*w*h = lwh
Now the question says
the height of the smaller box is 80% of the height of the larger box
It means
Height of the smaller box = 80% of h = 0.80*h = 0.80h
and the other two dimensions are same so it means length and width of the smaller box = l and w
so, Volume of the smaller box = l*w*0.80h = 0.80lwh
So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box
therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh
