If ( s )stands for speed and later in the question it says that the car was going 55 miles per hour you will replace the s in the equation with the number 55.
55=4.74d
Now you need to find ( d )
If you look at this equation another way you will see that what it’s saying is 4.74 x ? Is 55
Because d replaces the question mark
So 55 divided by 4.74 is 11.603 which is the answer

Answer:

C

Step-by-step explanation:

The inequality says greater than or equal to 8, which means the first two are automatically ruled out because they are both less than/equal to.

Then look at C and D, D starts at 3 and C starts at 8 so the answer should be C

Selina is playing a game that uses the spinner below.
MatroZZZ [7]

Answer:

A) 12.5%

B) 50%

C) 50%

Step-by-step explanation:

For A, 7 is one of the 8 possibilities (1/8). 1/8 of 100 is 12.5, so your chance of spinning a 7 is 12.5%

For B, even numbers are 4/8 or 1/2 of your options. 1/2 of 100 is 50, so your chance of spinning an even number is 50%

For C, there are 4 out of 8 numbers that are prime (2,3,5, & 7).

4/8 or 1/2 of 100 is 50, so your chance of spinning a prime number is 50%

hope this helps
