Verda used a sensor to measure the speed of a moving car at different times. At each time, the sensor measured the speed of the
USPshnik [31]

Answer:

Option A

Step-by-step explanation:

If the speed of a car in miles per hour (m) is proportional to the speed in kilometers per hour (k),

m ∝ k

m = ck

Here, c = Proportionality constant

Therefore, c = \frac{m}{k} should be constant for each value given in the table.

For m = 11 and k = 17.699,

c = \frac{11}{17.699}

c = 0.6215

For m = 26 and k = 41.834,

c = \frac{26}{41.834}

c = 0.6215

For m = 34 and k = 54.706,

c = \frac{34}{54.706}

c = 0.6215

Therefore, c is constant for each value of m and k.

Option A will be the correct option.

In ΔCDE, the measure of ∠E=90°, the measure of ∠D=23°, and EC = 1.3 feet. Find the length of DE to the nearest tenth of a foot?
Rina8888 [55]

Answer:

DE = 1.2ft

Step-by-step explanation:

It's actually a lot easier for someone to just draw a diagram. I recommend it in the future!

This is a right-angle triangle, so I'm guessing it's Sohcahtoa.

cos23° = DE/1.3

DE = 1.3cos 23°

DE = 1.1966...

Rounded:

DE = 1.2
