One student begins in Cleveland, Ohio, and walks towards Buffalo, New York, a distance of 200 miles. She walks at the rate of 2.

omeli [17]

Ok so student in cleveland walks 2.5 miles away from cleveland every hour from 8
so the distance, x is x=2.5t

the riding one rides 4 hours later, so t-4
11 mph
y=11(t-4)

A. x=2.5t
y=11(t-4)

when do they meet is when the distance when they are equal or when x=y
2.5t=x=y=11(t-4)
solve for t
2.5t=11(t-4)
2.5t=11t-44
-8.5t=-44
divide both sides by -8.5
t=5.17647

answer is 5.18 hours

A.
x=2.5t
y=11(t-4)

B. 5.18 hours

Triangle XYZ has coordinates X(2, 4), Y(−3, 4), and Z(−3, 1). If the triangle is translated using the rule (x, y) → (x − 2, y +

Crank

Y(−3, 4) is the original

(x, y) → (x − 2, y + 1) is the rule you're using

(-3, 4) → (-3 - 2, 4 + 1)

(-3, 4) → (-5, 5)

Y'(–5, 5)

If the perimeter of vectangle wall is 360 cm and its breath is 60cm. Find its length and also find the totalt cost of painting t

alexdok [17]

Answer:

Rs. 72

Step-by-step explanation:

We have 2 values here,

Perimeter of the rectangle = 360 cm
Breadth of the rectangle (b) = 60 cm.

Firstly, we must find the length of the rectangle (l).

So, according to the formula,

Perimeter = 2 (b + l)

360 = 2 (60 + l)

360 = 120 + 2l

360 - 120 = 2l

240 = 2l

120 cm = l

Now, we need to find the area of the rectangular wall & then convert it from cm² to m² as the cost of painting is given in m².

So,

Area = lb

Area = 120 × 60

Area = 7,200 cm²

Let's convert it to m² now,

7200/1000

= 7.2 m²

Given, cost of painting per m² = Rs. 10

So, the cost of painting the wall is,

10 × 7.2

= Rs. 72
