Answer:
37
Step-by-step explanation:
Let x be the smaller number. 2x+7 is the larger number. Their difference is 22:
x+22=2x+7
x=15
So the smaller number is 15 and the larger number is 2(15)+7=37.
It means that the two sides are congruent.
hope this helps !
Answer:
Step-by-step explanation:
Remark
<u>Question One</u>
It's equilateral. All three sides are equal. The base is 34 as well. So two right angles can be formed on the base by dropping the altitude from the top vertex.
Givens
altitude = h
a = 34/2 = 17
hypotenuse = 34
Formula
a^2 + h^2 = c^2
Solution
17^2 + h^2 = 34^2
289 + h^2 = 1156
h^2 +289 =1156
h^2 = 1156 - 289
h^2 = 867
sqrt(h^2) = sqrt(867)
h = 29.444
==============
<u>Question Two</u>
Givens
b = 10 feet
c = ?
height = h = 16
Formula
c^2 = b^2 + h^2
Solution
c^2 = 10^2 + 16^2
c^2 = 100 + 256
c^2 = 356
sqrt(c^2) = sqrt(356)
c = 18.87
7 days till the tank contains 14 gallons (if the day when it contains 42 gallons counts as day 0)
20h+40 two h plus eighteen h is 20h, while eight plus 32 is 40. subsitute eight into it, u get 160, then add 40, which is 200
$200
