a car covers a distance of 490 km with a speed of 70km and then covers a speed of 90km calculate its average speed

DaniilM [7]

Average speed = total distance divided by total time.

In the first part, the car covered 490 km in 7 hours, but I think you mistyped the second part (“then covers a speed of 90km”) and a critical piece is missing to find the total distance and time.

Suppose a certain home improvement outlet knows that the monthly demand for framing studs is 2,300 when the price is $4.77 each

pogonyaev

Answer:

p + 0.0001q = 5

Step-by-step explanation:

Data provided in the question:

When Price, p₁ = $4.77 ; Demand, q₁ = 2,300

and,

When Price, p₂ = 3,300 ; Demand, q₂ = 3,300

considering the above as the points on the line,

now, the general equation for a line is given as:

$\frac{q_1-q}{p_1-p}=\frac{q_2-q_1}{p_2-p_1}$

on substituting the respective values, we get

$\frac{2,300-q}{4.77-p}=\frac{3,300-2,300}{4.67-4.77}$

$\frac{2,300-q}{4.77-p}=\frac{1000}{-0.1}$

2,300 - q = -10,000(4.77 - p)

⇒ 2,300 - q = -47700 + 10,000p

⇒ 10,000p + q = 2300 + 47700

⇒ 10,000p + q = 50000

⇒ p + 0.0001q = 5

In the blueprint for A rectangular balcony is 1 inch by 1.75 inches if the actual length is 7 feet what is the perimeter

Elenna [48]

Answer:

22 feet

Step-by-step explanation:

Given

In blue print,dimensions of rectangular balcony are, length(l)=1.75inch and breadth(b)=1inch
The actual length(L)=7 feet

To find the actual perimeter, we need the breadth of balcony(B)

The ratio of length to breadth in blue print must be equal to the ratio of actual length to breadth

⇒

$\frac{\text{length of rectangular balcony in blueprint}}{\text{breadth of rectangular balcony in blueprint}} =\frac{\text{length of rectangular balcony actually}}{\text{breadth of rectangular balcony actually}}$
