Joe drove 200 km in 4 hours.At what rate did he drive?<br><br><br>​
Mandarinka [93]

Answer

50mph

Step-by-step explanation:  

rt=d use the rate times time equals distance method.

it gives us the time=4, use an exponent to represent the rate(since that's the information we don't have equals 200km

x times 4 = 200km

4x = 200km

Can someone help me with the below question???
8_murik_8 [283]

Answer:

so 2a+3b=±13

Step-by-step explanation:

4a²+9b²=97

ab=6

2a+3b=?

by using formula

(a+b)²=a²+b²+2ab

(2a+3b)²=(2a)²+(3b)²+2(2a)(3b)

(2a+3b)²=4a²+9b²+12ab

putting values

(2a+3b)²=97+12(6)

(2a+3b)²=97+72

(2a+3b)²=169

taking square root on both sides

√(2a+3b)²=√169

2a+3b=±13

i hope it will help you

<h3>Answer:  36%</h3>

============================================

Explanation:

There are 20 blue cards out of 10+20+25 = 55 cards total.

Divide the 20 over 55 to get

20/55 = 0.363636...

where the "36"s go on forever

So 20/55 = 0.3636 approximately

Move the decimal point over 2 spots to go from 0.3637 to 36.37%

Then round to the nearest percent: 36.37% ---> 36%

The probability of getting a blue card is approximately 36%
