Answers

Answer:

See Explanation

Step-by-step explanation:

[tex]cos (90-A).sinA + sin(90 - A).cosA = 1 \\ \\ LHS = cos (90-A).sinA + sin(90 - A).cosA \\ \\ = sinA.sinA + cosA.cosA\\ \\ = sin ^{2} A + cos^{2} A \\ \\ = 1 \\ \\=RHS\\\\ reason \\ cos (90- \theta) = sin \theta \\ sin (90- \theta) = cos \theta \\ sin ^{2} \theta + cos^{2} \theta = 1 \\ \\ thus \: proved \\ [/tex]

32. Solve the equation below.
12-13
= 17

Answers

12-13
12-13=-1
Therefore the equation is false.

Answer:

x = 2.5

Step-by-step explanation:

12x - 13 = 17

12x = 17 + 13

12x = 30 (divide both sides by 12 to get x)

12x/12 = 30/12

x = 2.5

What is the division?

The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.

Given that, 2/3 divided by 1/4

To divide fractions, keep first fraction as it is change division sign to multiplication and inverse the second fraction.

Here, 2/3 ÷1/4

= 2/3 ×4/1

= 8/3

= [tex]2\frac{2}{3}[/tex]

Therefore, the quotient of two fractions is [tex]2\frac{2}{3}[/tex].

Michael is buying a new pair of headphones from an electronics store. The headphones cost $15.50, but Michael has a coupon that will reduce the cost by $4.00. He must pay 6% sales tax on the discounted price of the headphones. How much will Michael pay in total for the headphones, including tax?

Answers

Answer: Michael pays $12.19 for the headphones including the tax.

Step-by-step explanation:

The initial price of the headphones was $15.50

When Michael uses his coupon, the price is decreased by $4, then the new price will be:

$15.50 - $4 = $11.50

Now Michael must pay 6% for taxes (on the discounted price), then he must pay:

$11.50 + (6%/100%)*$11.50

$11.50 + 0.06*$11.50

$11.50*1.06 = $12.19

Then Michael pays $12.19 for the headphones including tax.

Answer:

-20

-7

Step-by-step explanation:

0 x any number = 0

4(-5) = -20

126/(-18) = -7

Answer:

1. 0

2. -20

3. -7

Step-by-step explanation:

1. 0 times anything is equal to nothing times something.

So, the first one is 0.

2. For 4 x -5, you can just do 4 x 5 x -1, which equals 20 x -1, whixh equals -20.

3. Remember, a negative times a negative = a positive. So, the number must be negative. Just do 126 / 18 x -1, which equals -7.

Option C

Step-by-step explanation:

Given inequality is,

-3(2x - 4) ≤ 7(3 - x)

Solve the given inequality further,

-6x + 12 ≤ 21 - 7x

(-6x + 12) + 7x ≤ (21 - 7x) + 7x

x + 12 ≤ 21

(x + 12) - 12 ≤ 21 - 12

x ≤ 9 Or {x real | x ≤ 9}

Therefore, Option C will be the correct option.

Jing just got a new job. She started at a pay rate of $12.50 per hour and will get a $0.50 raise each year. Max started a job where is salary is found by the equation y=x+10, where x is the number of years. What is the initial value for Jing?

Answers

Answer:

initial value for Jing is $12.50.

Step-by-step explanation:

It is given that Jing started at a pay rate of $12.50 per hour and will get $0.50 per year. So, 0.50 is slope and y intercept is 12.50 for this equation.

The y intercept represents the initial value for the Jing.

So, initial value is $12.50.
