The ratio of Sarah's age to Keisha's age is 4:5 this year. Keisha was 12 years old 3 years ago. Find the ratio of Sarah's age to
KiRa [710]
First, we need to find her current age. If she was 12 years old 3 years ago, her current age is 12 + 3 which is 15. If the ratio of Sarah's age to Keisha's age is 4:5 (Sarah's age is the 4 and Keisha's age is the 5).
If we take 15 and divide that by 5 (her ratio), then you get 3. Now multiply 3 by 4 to find Sarah's age. We get 12. Nine years from now, her age is 12 + 9 which is 21.

There is the answer. Sarah's age in 9 years is 21 years old. I hope this helps.

11 Bob traveled 45 miles in 1.5 hours. The distance d and time I are in a proportional linear relationship Which graph represent
I am Lyosha [343]

Answer:

Graph (C)

Step-by-step explanation:

If Bob traveled 'y' miles in 'x' hours,

Distance traveled ∝ Time taken to cover the distance

y ∝ x

y = mx

Here, m = proportionality constant Or slope of the line

Since, Bob covered 45 miles in 1.5 hours,

m = \frac{45}{1.5}

m = 30 miles per hour

From the given graphs,

Graph (C) shows the slope = \frac{\text{Rise}}{\text{Run}}

                                             = \frac{60}{2}

                                             = 30 miles per hour

Therefore, Graph (C) will show the relationship.
