Answer:
450
Step-by-step explanation:
to start match up the inches (aka the base and the height) if the inches are the same you first times 45 and 10 because you need to find the area and your answer should be 450 because if you times any number by 10 you place a zero at the end hope this helps
Answer:
22 hours.
Step-by-step explanation:
Using algebra:
<u>6.5x</u> = <u>143</u>
6.5 6.5
x = 22
If angle of a sector is 115
the central angle would be 115 also
as the arc measure is equal to the measure of its central angle
131 3/4 ⇒ 115 5/8 ⇒ 5 2/3
Subtract 131 3/4 by 115 5/8.
131 3/4 ⇒ 131 6/8
131 6/8 - 115 5/8 = 16 1/8
Now add 16 1/8 + 5 2/3 and this will give you how much weight she lost in all.
16 1/8 ⇒ 16 3/24
5 2/3 ⇒ 5 16/24
16 3/24 + 5 16/24 = 21 19/24
Felice lost 21 19/24 pounds in all.
Sum = n/2[2a + (n - 1)d] where a = first term, n = number of terms and d = common difference
(a) 30/2(2 x 5 + (30 - 1) x d) = 1455
10 + 29d = 1455 / 15
29d = 97 - 10
d = 87 / 29 = 3
(b) 7/2(2 x 9 + (7 - 1)d) = 0
18 + 6d = 0
6d = -18
d = -3
