Omar grouped the terms and factored the GCF out of the groups of the polynomial 3x3 – 15x2 – 4x + 20. His work is shown. Step 1: (3x3 – 15x2) + (–4x + 20) Step 2: 3x2(x – 5) + 4(–x + 5) Omar noticed that he does not have a common factor. Which accurately describes what Omar should do next? A: Omar should realize that his work shows that the polynomial is prime. B: Omar should go back and regroup the terms in Step 1 as (3x3 – 15x2) – (4x + 20). C: In Step 2, Omar should factor only out of the first expression. D: Omar should factor out a negative from one of the groups so the binomials will be the same.

At another theater workers have to cut a new trap door.the door can be no mre than 130 sq ft in the area with whole number side lengths.they have to bring in 3 items to the stage.the first item is 6 feet,5 inches wide and 8 feet,9 inches long.the seconed item is 13 feet,4 inches wide and 7 feet, 8 inches long.the third item is 5 feet,6 inches wide and12 feet, 4 inches long. what size of trap door would you reccomend? what is the perimeter of the trap door

HhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhGiven:
trap door = 130 square feet.

1st item: 6ft 5in wide & 8ft 9in long 
⇒ (6ft * 12 in) + 5 in & (8ft *12 in) + 9 in
⇒ 77inches by 105 inches
⇒ 8,085 square inches

2nd item: 13ft 4in wide & 7ft 8in long
⇒ (13ft * 12in)+ 4 in & (7ft *12in) + 8 in
⇒ 160 inches by 92 inches
⇒ 14,720 square inches

3rd item: 5ft 6in wide & 12ft 4in long
⇒ (5 ft * 12in) + 6 in & (12ft * 12in) + 4in
⇒ 66 inches by 148 inches
⇒ 9,768 square inches

130 square feet convert to square inches.
130 sq. ft * 144 sq.in/sq.ft = 18,720 sq. in

18,720 sq. in / 160 inches = 117 inches

Length = 160 inches ; Width = 117 inches
Perimeter = 2(160 + 117)
P = 2(277)
P = 554 inches
P = 2(277)
P = 554 inches

What is the sine ratio of angle E? A - 5/3 B - 3/5 C - 5/4 D - 4/5

Answer:

The correct option is B.

Step-by-step explanation:

In a right angled triangle

\sin \theta=\frac{perpendicular}{hypotenuse}=\frac{opposite}{hypotenuse}

In the given triangle DEF, the opposite sides of angle E is DF=6 units and hypotenuse EF=10 units.

The sine ratio of angle E is

\sin E=\frac{DF}{EF}

\sin E=\frac{6}{10}

\sin E=\frac{3}{5}

The sine ratio of angle E is 3/5, therefore the correct option is B.

QUESTION POSTED AT 01/04/2020 - 01:38 PM

Your realized income is $2,415.64/month, and 54% are discretionary monies. If you want to save 3 months of fixed expenses for an emergency fund, how much must you save each month to fund it in 8 months

Answer:

$ 416.70 ( approx )

Step-by-step explanation:

Given,

The monthly income = $ 2,415.64,

Discretionary monies (Money left after expenses) = 54 % of the monthly income

Fixed expenses for a month = (100-54)% of total monthly income

= 46 % of total monthly income

= 0.46 ×  2,415.64

= $ 1,111.1944

Thus, the fixed expenses of 3 months = 3 × fixed expenses for a month

= 3 × 1,110.5544 = $ 3331.6632

Since, this money is saved in 8 months,

Hence, the amount of money saved per month = 1/8 of  $ 3331.6632

= $ 416.6979 ≈ $ 416.70

QUESTION POSTED AT 01/04/2020 - 01:37 PM

shoe salesman earns a commission of 30% of all shoe sales made. Yesterday he sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each. How much did he earn in commission yesterday? A. $111 B. $30 C. $42 D. $32

Answer:

$111 is earn by shoe salesman as commission .

Option (A) is correct .

Step-by-step explanation:

As given the statement in the question be as follow.

Shoes salesman sold 3 pairs of shoes for $70 each and 2 pairs of shoes for $80 each.

Thus

Total cost of the pair of shoes = 3 × 70 + 2 × 80

                                                  = 210 + 160

                                                  = $ 370

As given

shoe salesman earns a commission of 30% of all shoe sales made.

30% is written is decimal form

= \frac{30}{100}

= 0.30

Commission earns = 0.30 × Total cost of the pair of shoes .

                               = 0.30 × 370

                               = $ 111

Therefore $111 is earn by shoe salesman as commission .

Option (A) is correct .
