Answer:
65 dm and 52 dm
Step-by-step explanation:
If the scale factor of the sides is k, then the scale factor of the areas is k^2.
The scale factor of the areas is (32 dm^2)/(50 dm^2) = 0.64 = k^2
The scale factor of the sides is k = \sqrt(0.64) = 0.8
The perimeters are in a ratio of 1:0.8
x + 0.8x = 117
1.8x = 117
x = 65
0.8x = 0.8(65) = 52
The perimeters are 65 dm and 52 dm.
Answer:
95%
Step-by-step explanation:
Total distance of trip = 980 miles
Miles covered when Amelia slept = 931 miles
what percentage of the total trip had they travelled when Amelia fell asleep?
Miles yet to be covered = 980 miles - 931 miles
= 49 miles
percentage of the total trip had they travelled when Amelia fell asleep = 931 / 980 × 100
= 0.95 * 100
= 95%
Answer: It will land on the bush after 1.25 seconds.
First, we will start with what we are given the equation: h(t) = -16t^2 + 30
Now, we should input a 5 for the h(t) because we want the seconds that will give us a height of 5 seconds.
5 = -16t^2 + 30
Solve the equation:
0 = -16t^2 + 25
To solve this, you could use the quadratic formula or factor out a -1 and you will have the difference of two squares.
Either way the answer is 1.25 seconds.
get the total units made:
170 + 165 + 149 + 157 + 181 = 822 units.
Multiply by pay:
822 x 0.12 = $98.64
