3.4% in decimal form is .034 = r
2014 - 2004 = 10 years = t
A = 45,000(1+.034)^10
A= 62,866
Answer:
b=320; slope=-30
Step-by-step explanation:
if you look along the y-axis find the spot that the line intercepts and then that's b
now for the slope
find two points on the line, i chose(8 , 120) and (4 , 240)
use the slope formula: y2-y1 over x2-x1
240-120=120 and 4-8= -4
so the slope is 120/-4 and that can be simplified to 30/-1 or -30
Answer:
and 
Step-by-step explanation:
At=As+Ar; A=b.h and 
, then: At=(x+120)x so
(x+120)x=4500, 
Applying cuadratic equation formula:
<span>A parallelogram is a 4-sided shape formed by two pairs of parallel lines. Opposite sides are parellel separately, so each pair of opposite sides have equal lengths and angles. To find the area of a parallelogram, multiply its base by height. The formula is:
A(rea) = B(ase) * H(eight)
* means multiply.
In the question, the area of the parallelogram is known as 45 square miles, which means:
45 = B * H
So we need to find out all the possible pair of factors, whose product is 45:
1 * 45 = 45
3 * 15 = 45
5 * 9 = 45
Then we know base and height will fall into each pair:
1 * 45 = 45
=> B = 1 miles, H = 45 miles or B = 45 miles, H = 1 miles
3 * 15 = 45
=> B = 3 miles, H = 15 miles or B = 15 miles, H = 3 miles
5 * 9 = 45
=> B = 5 miles, H = 9 miles or B = 9 miles, H = 5 miles</span>
40x + 50x = 750
90x = 750
x = 750 / 90 = 8.333 hours
40 * 8.33 = 333.4
50 * 8.33 = 416.6
8.33 hours = 8 hours and 20 mintutes
