Yes because when u add 8+3 u get 11 and anything larger than 9 u have to regroup and put the 10's place on top of the 1st number and the 1's place under the sum line then u add the other 2 numbers to get 43+28=71. Hope that helps u

You are looking for a speed in miles per hour, so start by converting 90 minutes into hours.

90/60 = 1.5

90 minutes = 1.5 hours

speed = distance/time = (105 miles)/(1.5 hours) = 70 mph

25.35. Here's what you do, if those numbers are multiplied by a 100, they'd be40% red, and 25% blue. So the white is the rest. So you add 25%+40%=100%;
Answer: 35%. Divide by 100, .35. Boom! you got your answer;)

What’s the correct answer for this?

Answer:

(x + 5)² + (y - 7)² = 13

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 5, 7) and r = $\sqrt{13}$ , thus

(x - (- 5))² + (y - 7)² = ( $\sqrt{13}$ )² , that is

(x + 5)² + (y - 7)² = 13 ← equation of circle
