Answer:
23
m/s
Step-by-step explanation:
We can change the km to m first. 1km = 1000m.
84km/h = 84 000m/h
Then, we can change the h to s. 1h = 3600s.
84 000m/h = 23
m/s
These rates are not in proportion. Juan walked faster.
Explanation:
First, we want to make these ratios to have the same denominator so we can compare the numerators. To do this, do 3x5 and 8x5 to get 40:15. Then, we do 5x3 and 14x3 to get 42:15. Now we can just compare the numbers 40 and 42, and since 42 < 40, we know Juan walked faster.
Maybe try 4(2-y)=2y for an equation
Answer:
<h2>The dimensions of the third blanket are 7.5 feet by 6 feet.</h2><h2>All the blankets are similar.</h2>
Step-by-step explanation:
The size of the first blanket is 2.5 feet by 2 feet.
Shannon wants to enlarge the first blanket by scale factor 2 to make the second blanket.
Hence, the size of the second blanket will be
feet by
feet.
Again she enlarged the second blanket by a scale factor 1.5 to make the third blanket.
Hence, the size of the second blanket will be
feet by
feet.
Enlargement only changes the size of the blanket, it does not change the shape of the blanket. Hence, all the blankets will be similar.
