What additional information must be known to prove the triangles similar by SAS?

Answer:

12%

Step-by-step explanation:

Percentage discount

[tex] = \frac{discount}{original \: price} \times 100\% \\ = \frac{90 - 79.20}{90} \times 100\% \\ = 12\%[/tex]

☆ Discount= original price -marked price

Answer:

y=4/5x-4

Step-by-step explanation:

use formulas (y2-y1)/(x2-x1) and y=mx+b

slope (y2-y1)/(x2-x1):

(8-0)/(5-(-5))

=8/10

=4/5

equation (y=mx+b):

0=4/5(5)+b

0=4+b

b=-4

Answer:

Shandra would pay $27.50 for 5 slices

Cost = 20+1.50x

Step-by-step explanation:

Given

[tex]Membership = \$20[/tex]

[tex]Discounted\ Price = \$1.50[/tex] per slice

Solving (a): Cost of 5 slices

Represent the total price with y and the number of slice with x.

So, we have:

[tex]y = Membership + Discounted\ Price * x[/tex]

This gives:

[tex]y = 20+ 1.50* x[/tex]

In this case: x = 5.

So, we have:

[tex]y = 20+ 1.50* 5[/tex]

[tex]y = 20+ 7.50[/tex]

[tex]y = 27.50[/tex]

Shandra would pay $27.50 for 5 slices

Solving (b): Cost of x slices

This has been solved in (a).

[tex]y = 20+ 1.50* x[/tex]

[tex]y = 20+1.50x[/tex]

Hence, the cost of x slices is 20+1.50x

Answer:

[tex]0.0467[/tex] is the probability that none of the graduates have a summer job

Step-by-step explanation:

Here

P [tex]= 0.40[/tex] and n [tex]= 6[/tex]

Probability that none of the graduate gets job

this means that x = 0

P (x = 0) [tex]= ^6C_0 * (0.40)^0 * (0.60)^6[/tex]

P (x = 0) [tex]= 0.0467[/tex]

Answer:

Outcome of complementary event of getting "2 or greater" on the spinner = {1}

Step-by-step explanation:

Let A be an event of getting '' 2 or greater ''

The complementary event of A be = A' = getting ''less than 2 ''

Now,

The Sample space S = { 1, 2, 3, 4 }

Outcome of A' = { 1 }

∴ we get

Outcome of complementary event of getting "2 or greater" on the spinner = {1}

Then you simplify to get 3/40

Answer:

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

Step-by-step explanation:

As given ,

                                       Windbreakers          Rain breakers              Total

Finishing time                         59 min                     58 min                   61 hr

Packaging time                        21 min                      34 min                   68 hr

Profit                                          28                                41

Let

The number of windbreaker jackets they should produce = x

The number of rain breaker jackets they should produce = y

As given,

The company wants to maximize profit.

⇒ Maximum Profit , p = 28x + 41 y

Now,

As 1 hour = 60 min

⇒61 hours = 61×60 = 3660 min

and 67 hours = 67×60 = 4020 min

∴ we get

The equations become

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

So, the Linear Programming Problem (LPP) for this problem is -

Max p = 28x + 41y

Subject to

59x + 58y ≤ 3660

21x + 34y ≤ 4020

x  ≥  0, y ≥ 0

Answer:

17x+7y+10

Step-by-step explanation:

y+4+3(y+2)

you have to multiply 3 by the numbers/variables in the parenthesis

y+4+3y+5

Do the same to the other equation

5x+3(y+4x)

5x+3y+12x

Set an equation that will let you add their like terms.

y+4+3y+5+5x+3y+12x

I'm going to add like terms with the y

y+3y+3y = 7y

Now like terms with x

5x+12x = 17x

Now put them all as a single equation

17x+7y+10

Answer:

1. x = 6 check: 3 * 6 = 18

2. x = -12 check: -12/3 = -4

3. x = 11 check: 11 * 11 = 121

4. y = -4 check: -8 * -4 = 32

Step-by-step explanation:

1. x=6 ( 3×6=18)

2. x = -12 (-12÷3 = -4)

3. x=11 (11×11=121)

4 y=-4 (-8 × -4 = 32)

Answer:

592.83 ft^2

Step-by-step explanation:

First estimate the area of the rectangle:

Area rectangle = Base x Height = 20 * 36 = 720 ft^2

and then subtract from it the area of a semi-circle of radius 18/2 = 9 ft

Using the formula for the semicircle's area:

Semi-circle's area= pi * R^2 / 2 = 3.14 * 9^2 / 2 = 127.17 ft^2

Such gives us:

720 ft^2 - 127.17 ft^2 = 592.83 ft^2
