Answer:
Step-by-step explanation:
Analyzing the growth rate of 1.07:
If the growth rate is a number greater than 1, we have exponential growth; if the growth rate is a number greater than 0 but less than 1, we have exponential decay.
Our growth rate is actually growth. But the rate of growth is not 107%. The rate of growth means that we already had 100% of the population and that it is growing by 7% each year. 100% + 7% = 107%; as a decimal, 1.07
So the rate of growth is 7%
Answer:
A:60
Step-by-step explanation:
9ftx10ft= 90 ft squared = 1080 inches
1080/36 (6x6=36) inches= 30 white tiles x2 because of the ratio
60 white tiles
Answer:
3/2
Step-by-step explanation:
Because the problem tells you that the two triangles are similar, the value of a/b would be equivalent for both triangles. The fact that they are right triangles also indicates which sides are which in case the image was not drawn to scale. A is proportional to 2.1 and b is proportional to 1.4. So a/b= 2.1/1.4. This can reduce itself to 3/2 because both are divisible by .7
Answer:
5 hours
Step-by-step explanation:
2 first hours cost 4.00 which equals 8.00
Additional hours cost 1.50
So we know he already has to pay 8.00 for the first 2 hours
now you just subtract 8.00 from 12.50 which equals 4.50
If one hour is 1.50 Then 2 hours is 3.00 so we subtract 3.00 from 4.50 which equals 1.50 and 1.50 equalss another hour
y=4x+1.50

➷ 1) (3(3) + 4.5) - |-5| = 8.5
2) (4(5) - (15)^2 = 25
3) (2)^3 - 6 - 4 = -2
4) 3(-10) - 5(6) = -60
5) 6 + 1/2(10 + 8) = 15
6) square root of (4 + (6 x 5)) = 5.830951895
