Answer:
x = 20
Step-by-step explanation:
7x - 99= 2x + 1
7x - 2x = 1 + 99
5x = 100
x = 20
Answer:
Radius = 2.90 cm
Step-by-step explanation:
220 = 3.14 × {r}^{2} × 8.3
220 = 26.062 × {r}^{2}
220/26.062 = {r}^{2}
{r}^{2} = 8.44 ( approx )
r = √8.44
r = 2.90 cm. (approx)

Answer:
A) $1250
Step-by-step explanation:
p=$2500
r=10%
t=5yrs
i=p*r*t/100
i=2500*10*5/100
i=25*10*5
i=$1250
Answer:
21 in
Step-by-step explanation:
The law of cosines is helpful for this. The angle opposite the shorter diagonal is the supplement of the angle shown, so is 60°.
If we designate the known sides as "a" and "b", the short diagonal as "c" and the smaller angle as C, then the law of cosines tells us ...
c^2 = a^2 + b^2 -2ab·cos(C)
For the given dimensions, we have ...
c = √(15^2 +24^2 -2·15·24·cos(60°)) = √441 = 21 . . . inches
Answer:
See below in bold.
Step-by-step explanation:
Mean = 150 cm = 150 * 0.033 feet
= 4.95 feet.
The standard deviation = 10 cm = 10 * 0.033
= 0.33 feet.
