Answer:

the ratio of Jan's average walking rate to Bev's average walking rate is 3/4 or 3 : 4

Step-by-step explanation:

Let x and y represent jan and Bev's average walk rate.

Also t represent the time taken for Bev to walk 4 miles, so it will take jan 2t time to walk 6 miles

Given that;

It takes Jan twice as many hours to walk 6 miles as it takes Bev to walk 4 miles

For Bev;

y = 4/t

For Jan;

x = 6/(2t) = 3/t

the ratio of Jan's average walking rate to Bev's average walking rate is;

x/y = (3/t)/(4/t) = 3/4

the ratio of Jan's average walking rate to Bev's average walking rate is 3/4 or 3 : 4

Answer:

Step-by-step explanation:

When you find the sum of 3 and 5 you get 8, which represents the total number of vehicles used in the trucks to cars ratio.

This means that the ratio of cars to total vehicles in this ratio is 5 to 8. Because there are 24 vehicles in the parking lot, and 8 × 3 = 24, you can multiply the entire ratio by three to get your answer:

5 to 8 ⇒ 15 to 24

Therefore, the number of cars in the parking lot is 15.

Your answer will be f(x) = 5 because, if we look at the table, no matter what x value we plug into the function, we will always get 5.

What is the apparent slope of the line graphed below

maria [59]

I think the answer would be -2.5 because 0-5=-5 and 4-2=2 you subtract the perfect points X1-x2 with y2-y1

12. In the given figure, RS is parallel to PQ, If RS = 3 cm, PQ = 6 cm and ar(∆TRS) = 15cm³, then ar (∆TPQ) = ? (a) 70 cm² (b) 5

Gnesinka [82]

$\large\underline{\sf{Solution-}}$

Given that,

In triangle TPQ, 

RS || PQ,

RS = 3 cm,

PQ = 6 cm,

ar(∆ TRS) = 15 sq. cm

As it is given that, RS || PQ

So, it means

⇛∠TRS = ∠TPQ [ Corresponding angles ]

⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

$\rm\implies \: \triangle TPQ \: \sim \: \triangle TRS \: \: \: \: \: \: \{AA \}$

Now, We know 

Area Ratio Theorem,

This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{ar( \triangle \: TRS)} = \dfrac{ {PQ}^{2} }{ {RS}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{ {6}^{2} }{ {3}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{36 }{9}$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = 4$

$\rm\implies \:ar( \triangle \: TPQ) = 60 \: {cm}^{2}$
