Answer:
-10
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
5(x – 2) = 30
Distribute:
5x - 10 =30
Add 10 to both sides:
5x = 40
Divide
x=8
Check your work:
5(8 - 2) =30
5(6) =30
5 * 6=30
30=30!
Final answer: x=8
It takes about 20 minutes to grade a student’s paper. How long, in hours, does it take to grade papers for a class of 30 people?
Answer:
it would take around 10 hours to grade all 30 papers
Step-by-step explanation:
if for one student it takes 20 minutes that means you would have to do 20 minutes 30 times which is 600 minutes. to convert that to hours you divide total minutes (600) by 60 which gives you 10 hours. no need for thanks
Which of the following functions is graphed below
Answer:
D
Step-by-step explanation:
The first function is true when x<4. We know this because all of the points are to the left of 4, and all these numbers are all less than 4. Also, the circle is open so it should not include 4.
Simplify 3^2 • 3^5. (4 points)
3^7
3^10
9^7
9^10
Answer:3^7
Step-by-step explanation:
(3^2)(3^5)=(3×3)(3×3×3×3×3) =3×3×3×3×3×3×3=3^7

Cindy plans to invest for 10 years at 1.5%, compounded annually. If she hopes to have $10,000 after 10 years, how much
will she need to invest initially?
Answer:
Use the formula for calculating compound interest PN=P0(1+rk)Nk where P0 is the unknown, PN=10,000, N=10, k=1, and r=0.015. Substitute the values into the formula and simplify.
10000=P(1+0.0151)1⋅10
10000=P(1.015)10
10000=P(1.16054...)
8616.67=P
Therefore, rounded to the nearest dollar, the initial investment needs to be $8617 to have $10,000 in 10 years.

itz only 1 question
Answer:
A = 54 units ^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height
A = 1/2 ( 18) * ( 6)
A = 54 units ^2
Answer:
54 units²
Step-by-step explanation:
Hello! :)
I don't know which equation your teacher wants you to use for the Area of a Triangle, but this is how I do it:
A= ½(b*h)
A= ½(18*6)
A= ½ (108)
A= 54
--------------------
If you prefer an explanation in word form, here you go:
The area of a triangle is Area= one-half, multiplied by its base and height.
A= ½(b*h)
So in this question, the base(b)= 18 and the height(h)= 6.
A= ½(18*6)
Then, you just solve the math problem (shown up above)!
Good luck with your homework, and I don't need a brainliest I just wanted to help! :)

Find the area of the figure. Explain your reasoning.
Answer:
Separate it into smaller figures.
Step-by-step explanation:
The figure can be separated into a triangle on the top, and 2 trapezoids on the middle and the bottom.
The area of the triangle is bh/2, which is (4 x 6)/2, which is 12.
The area of the trapezoid in the middle is .5(b1+b2)h, which is .5(6+4)3, which is 15.
The area of the trapezoid on the bottom is .5(6+5)2, which is 11.
Now, add them to get 12+11+15 which is 38.
Answer: Not sure I have this problem too and i’m trying to figure it out.
Step-by-step explanation:
It’s not 38. There is another two other triangles and a rectangle, along with a square. The triangles formula is a=bxh/2 and the parallelogram or rectangles formula is bxh.
Once your done, you add all them together.
The two other triangles are in the middle in the little corner, and the other one in the bottom left corner.
Solving the for angle NMP.
Answer:
I would say 75 because it looks like the little parts that aren't part of the triangle take up ab 25% of the circle so I subtracted 25 from 10 and got 75

The Ratio of boys to girls at Space Camp is 3:2. The Total number of campers is 60. How many campers are girls? Make a tape diagram to illustrate your answer. Highlight One answer in Green.
A. 12
B. 24
C. 36
D. 40
Answer: B. 24
Step-by-step explanation: 60 divided by 5 is 12. Twelve times two (the amount of girls) is 24. Twelve times 3 (the amount of boys) is 36. Since 24 + 36 = 60, there are 24 girls and 36 boys.
