Answer:
72
Step-by-step explanation:
Call the amount she started with, x
she removes 2
x - 2
then she divides it by 10
(x - 2)/10
each bag contains 7 pieces
(x - 2)/10 = 7
so now solve using inverse operations
(x - 2)/10 = 7
*10 *10
x - 2 = 70
+2 +2
x = 72
What is the mean of the values: 10, 20, 35, 35, 35, 40, 45, 45, 50, 60
Answer:
the mean is 37.5
Step-by-step explanation:
you get this by adding all the values and then dividing by how many values there are.
The mean of the given values will be equal to 37.5.
The numbers given are 10, 20, 35, 35, 35, 40, 45, 45, 50 and 60
We have to find out the mean of the given numbers.
What is mean ?
The mean is equal to the sum of given numbers divided by the total number of numbers.
As per the question ,
Numbers given are ; 10, 20, 35, 35, 35, 40, 45, 45, 50 and 60
The sum of all above numbers is ;
= 10 + 20 + 35 + 35 + 35 + 40 + 45 + 45 + 50 + 60
= 375
and
Total number of numbers = 10
So , the mean will be ;
Mean = sum of all numbers / total number of numbers
⇒ Mean = [tex]\frac{375}{10}[/tex]
⇒ Mean = 37.5
Thus , the mean of the given values will be equal to 37.5.

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.

Sal made 6 ft of sausage links on Friday morning. He used 3 ft for dinner service on Friday night. On Saturday morning, he made another 6 ft of sausage links and used 9 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night? A. 1 ft B. -1 ft C. 2 ft D. 0 ft
Answer:
-6 ... even though it is not one of the options would be the correct answer.
Step-by-step explanation:
In order to solve this problem we can take it one step at a time. Sal started Friday morning with 6ft of sausage
6ft
He used 3ft for dinner on Friday night which means he subtracted 3ft.
6ft - 3ft = 3ft
He made another 6ft Saturday morning which means he added to his existing sausage link.
3ft + 6ft = 9ft
Finally, he used 9ft for dinner Saturday Night which means he subtracted 9ft.
9ft - 9ft = 0ft
Therefore, the net change would be -6 since Sal started with 6ft and ended with 0ft during this time.

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.

In the following figure (AB) (CD). Suppose that m<1=32 (degrees). What is the m<6 ? Explain your reasoning.
Answer:
m∠6 = 148°
Step-by-step explanation:
From the figure attached,
AB and CD are two parallel line and another transverse line is intersecting these line at two distinct points.
Since, m∠1 = 32°,
∠1 and ∠4 are supplementary angles [Linear pair of angles]
m∠1 + m∠4 = 180°
32° + m∠4 = 180°
m∠4 = 180° - 32°
m∠4 = 148°
Since, ∠4 ≅ ∠6 [Alternate interior angles]
m∠4 = m∠6 = 148°
Therefore, m∠6 = 148°
Answer:
148°Step-by-step explanation:

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! :)
