Answer:

Total cost for curtains = Rs.3,700

Step-by-step explanation:

Assume we have:

1 Door ( l = 8ft, b=4ft)

3 Windows (l = 4t, b = 3.5ft)

Curtains at the rate of Rs.50 per ft²

Find:

Total cost for curtains.

Computation:

Area of door = (8)(4)

Area of door = 32 ft²

Area of 3 windows = (3)(4)(3.5)

Area of 3 windows = 42 ft²

Total ares = Area of door + Area of 3 windows

Total ares = 32 ft² + 42 ft²

Total ares = 74 ft²

Total cost for curtains = Rs.50 × Total ares

Total cost for curtains = Rs.50 × 74 ft²

Total cost for curtains = Rs.3,700

Answer:

The parabolic equation does not intersect the linear equation.

Explanation:

Given equation's:

y = x² − 5x + 9
y = -2x

To solve , use substitution method by inserting 2nd equation into 1st

$\sf y = x^2 - 5x + 9$

when substituted y = -2x

$\sf -2x = x^2 - 5x + 9$

collect terms

$\sf x^2 - 5x+ 2x + 9=0$

simplify

$\sf x^2 - 3x + 9=0$

Find discriminant:

$\sf b^2 - 4ac$

$\sf (-3)^2 - 4(1)(9)$

$\sf -27$

As the discriminant is negative, it tell us that they both does not intersect each other.

Allison plays basketball and last season she made a total of 87 shots (two- or three-point shots). Her point total was 191 . How

Answer:

She made 17 three-point shots.

Step-by-step explanation:

Let t represent the number of three-point shots she made.

Since, she made a total of 87 shots (two- or three-point shots), the number of two-point shots will be 87-t.

The points from three-point shots:

→ 3t (1)

The points from two-point shots:

→ 2(87-t) (2)

Since, her total point was 191, the sum of equation 1 and equation 2 must be equal to 191.

→ 3t + 2(87-t) = 191

→ 3t + 174 - 2t = 191

→ t = 17
