Answer:
$80
Step-by-step explanation:
From the question, we are given The simple interest formula as I = Prt,
where l = simple interest on an amount= $40
t= years=5years
at a rate r= 10%
The rate= 10/100= 0.1
Then since we are looking for P, we can make P subject of formula from this expression;
I = Prt
P=I/rt
P= 40/(0.1 ×5)
P= 40/0.5
P= 80
therefore, the amount of money p that is needed is $80
Answer:
V = 567 ft³
Step-by-step explanation:
V = Bh
<em>[note: a capital 'B' represents the </em><em>area</em><em> of the base] </em>

The right triangle is the triangular prism's base.
Because the triangle's height (9 ft) and it's base are the same value (9 ft), we can solve to find the area.
- We can identify the base easily because the base and the top of the prism are exactly the same shape
Area of triangular base:
A = 
A = 
(9 ⋅ 9)
A = (81)
A = 40.5
We have 'B' for the triangular prism's formula, so next we need 'h'. 14 ft is provided as the prism's height, so we just need to multiply 40.5 and 14 for our answer.
Volume of triangular prism:
V = Bh
V = (40.5)(14)
V = 567 ft³
3 5/7 x 2 6/7
= 3.71428564 x 2.8571428
= 10.6 ft^2 (3 sig. fig.)
Answer:
Step-by-step explanation:
time = 49 hours
speed = 7 miles/hour
speed = distance / time
∴ distance = speed × time
= 7 × 49
= 343 miles
Answer:
d. 84.5
Step-by-step explanation:
You will have to put the numbers in order than cross out one from each side;
70x
80x
83
86
88x
88x
In doing this you have taken out B,E, and F. The answer would have to be somewhere in between 83 and 86, which would be around 84 and 85, so therefore the answer would be 84.5
