Answers

Answer 1

Answer: 20.1

Step-by-step explanation: I if you are here from delta math this is the answer

Answer 2

Answer: 20.1

Step-by-step explanation:

sinU=

hypotenuse

opposite

\sin 85=\frac{20}{x}

sin85=

x\sin 85=20

xsin85=20

Cross multiply.

\frac{x\sin 85}{\sin 85}=\frac{20}{\sin 85}

sin85

xsin85

sin85

Divide each side by sin 85.

x=\frac{20}{\sin 85}=20.0764\approx 20.1\text{ feet}

sin85

=20.0764≈20.1 feet

Type into calculator and roundto the nearest tenth of a foot.

20.1

(opposite of ∠U)

(adj. to ∠U)

(hypotenuse)

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?

Answers

Answer:

21.4 feets

Step-by-step explanation:

Using Pythagoras rule :

The length of the string:

Hypotenus = sqrt(opposite² + adjacent²)

Length of string = sqrt(17² + 13²)

Length = sqrt(289 + 169)

Length of string = sqrt(458)

Length of string = 21.400

Length = 21.4 feets

Apple juice and cranberry juice have been mixed in the ratio of 4:5. If the price of apple juice is 45 cents per pint and the price of cranberry juice is $0.8 per pint, what should the price of one pint of the mixture be?

Answers

Answer:

$0.24

Step-by-step explanation:

The computation of the price of the one pint of the mixture is shown below:

Since the ratio of apple juice and cranberry juice is 4:5

And, the price of apple juice is 45 cents i.e. = 0.45 × 4 ÷ 9 = 0.2

Also the price of cranberry juice is $0.8 = $0.08 × 5 ÷ 9 = 0.04

SO, the price of one pint of the mixture is

= 0.2 + 0.04

= $0.24

Answer:

$0.24444

Answers

Answer:

Step-by-step explanation:

Perimeter of the given polygon = n + 2 + 3 + 4 + n + 2 + 3 + 4

= 2(n + 2 + 3 + 4)

= 2(n + 9) units

Area of the composite figure = Area of rectangle A + Area of rectangle B + Area of rectangle C

= (3 × 4) + (n ×2) + (2 × 3)

= 12 + 2n + 6

= 2n + 18

= 2(n + 9) units²

Therefore, perimeter of the given figure = Area of the figure

= 6x³ - 3x² + 4x - 4 - 9x² - x + 1

Write an equation that could be used to find the value of x using the interior angles of ∆BDC, then solve it.

Answers

9514 1404 393

Answer:

x = 16

Step-by-step explanation:

Either or both of the right triangles can be used to find x. Or, triangle ABC could be used. All numbers are assumed to be degrees.

Using ∆ABD

55 +90 +2x+3 = 180

2x = 32 . . . . . . subtract 148

x = 16

Using ∆BCD

50 +90 +2x+8 = 180

2x = 32 . . . . . . subtract 148

x = 16

Using ∆ABC

55 +(2x +3) +50 +(2x +8) = 180

4x = 64 . . . . . . . subtract 116

x = 16

A store purchased a plasma screen TV for $770 and marked it up 150%. During a sale, the store marked it down 20%. What was the discount price on the plasma screen TV?

Answers

Answer:

1540

Step-by-step explanation:

First find the new price after the markup

The markup is

770 * 150%

770 * 1.5

1155

Add this to the original price

770 + 1155

1925

Now find the discount

1925*20%

1925*.20

385

Subtract this amount from the 1925

1925-385

1540

The final price is 1540

Answer:

Solution given:

cost price [c.p] of TV =$770

MP=c.p+ 150% of c.p=$770+150/100×770=$1925

discount [D]=20%

now

discount amount=D% of MP=20/100×1925=$385 is your answer.

$385 was the discount price on the plasma screen TV.

Find the degree measure of the angle expressed by 11x-6.

Answers

Answer:

Won't it just be 60, because it's an equilateral triangle.

Step-by-step explanation:

60 + 60 = 120

180 - 120 = 60

11x - 6 = 60

11x = 66

x = 66/11

x = 6

Let's substitute.

11(6) - 6 = 66 - 6 = 60

Answers

Answer:

0.0016

Step-by-step explanation:

The expression 0.2 by the power of 4 when evaluated has a value of 0.0016

How to evaluate the expression

From the question, we have the following parameters that can be used in our computation:

0.2 by the power of 4

Express as an equation

So, we have

0.2 by the power of 4 = 0.2⁴

When expanded, we have

0.2 by the power of 4 = 0.2 * 0.2 * 0.2 * 0.2

Evaluate the products

This gives

0.2 by the power of 4 = 0.0016

Hence, the solution is 0.0016
