Answer:
Step-by-step explanation:
arithmetic sequence: 60,68,76,......
a = 60
d = 68 - 60 = 8
an = a + (n-1)*d
a20 = 60 + 19 * 8
= 60 + 152
= 112
There are 112 seats in the 20th row
We have the perimeter of a base P = 20".
We have five congruent rectangles that together form a large rectangle
20" × 6".
The Lateral Area:
L.A. = 20 in · 6 in = 120 in²
Answer:
6d+49.8
If looking for d=8.316 but 6 is repeated

Answer:
B. $200,000
Step-by-step explanation:
Let x be the amount placed at 5.5%
3x is the amount placed at 5%
This leaves the rest for the 4.5 % 500000- x - 3x = 500000-4x
Assuming simple interest
I = PRT where I is interest, P is principle, rate is rate and t is time
Interest for the 5.5% for 1 year is
I = x * .055 * 1 = .055x
Interest for the 5.% for 1 year is
I = 3x * .05 * 1 = .15x
Interest for the 4.5% for 1 year is
I = 500000-4x * .045 * 1 = 22500 - 0.18 x
Add the interest together to get the income for 1 year
.055x+ .15x+22500 - 0.18 x=25,000
Combine like terms
0.025x+22500=25000
Subtract 22500
.025x =2500
Divide by .025
x =100000
short term notes is 100000
3*x = 300000 = government bonds
The rest is utility bonds 500000- 100000-300000 = 100000
We want how much more in government bond than utility bond
300000 -100000 = 200000
Answer:

Step-by-step explanation:
- this can be done by simple manipulation .
- in the given equation, A is the subject.
- so, by the above statement you can understand the meaning of making something as a subject.
- given equation: A = 1/2 bh
- multiply both the sides by 2,
2A = bh
- divide both the sides by h,

so, the required form is :
