Answer:

66.7 in^3

Step-by-step explanation:

The volume of a triangular pyramid is given by

V = 1/3 B h

where B is the area of the base and h is the height

Calculate the area of the base.  The base is a triangle

B = 1/2 bh  where b is 8 and h is 5

  = 1/2 (8) * 5

  =20

V = 1/3 (20) 10

 66.6666666

To the nearest tenth

Answer:

66.7 in³

Step-by-step explanation:

Volume = ⅓ base area × height

= ⅓(½ × 5 × 8) × 10

= ⅓ × 20 × 10

= 200/3 in³

= 66.6667 in³

at the start of the shift your part counter reads 250 at the end of the shift the part counter reads 1075 how many parts did you
Luden [163]
This can be mathematically expressed to
 250 + X  = 1075
where X represents the parts you produce before the shift ends
Transpose 250 to the other side by subtracting each side by 250
Thus, it goes like this
X = 1075 - 250
X = 825

You produced 825 parts in the middle of the shift.

6,000 dollars is invested in two different accounts earning 3%and 5% interest. At the end of the year, the two accounts earned 2
nadezda [96]
Hi there

To solve this question
0.03x+0.05 (6000-x)=220
Solve for x to know How much money was invested at 3%
First multiply the values
0.03x+0.05×6000-0.05x=220
0.03x+300-0.05x=220
Second calculate the difference and rearranging the values
0.03x-0.05x=220-300
-0.02x=-80
Divide both sides by-0.02 and divide the values
X=-0.02/-80
x=4000 invested at 3% this is the answer of your question

While the amount invested at 5% is
6000-4000=2000

Good luck!
