The price of a silk scarf is $32. The sales tax is $1.92. What is the sales-tax rate?

Answers

Answer 1

Answer:

Answer:

sales-tax rate = 6%

Step-by-step explanation:

The price of a silk scarf is $32. The sales tax is $1.92

Let the sale tax rate be s%

Price of silk scarf = $32

Sale tax = s% of 32

Sale tax = $1.92

Thus,

s% of 32 = 1.92

First we change s% to decimal

$(s)/(100)* 32=1.92$

$s=(1.92* 100)/(32)$

$s=6\%$

Hence, The sales-tax rate is 6%

Answer 2

Answer: The sales tax =1.92/32.00=0.06=6%

A rectangle has an area of 8 square centimmetres and a perimeter of 12 cm. What are the width and breath?

Answers

Let the Length be L and the Width be W

The area is 8 cm²
LW = 8

The perimeter is 12
2(L + W) = 12
L + W = 6

Solve L and W:
LW = 8 --------------- (1)
L + W = 6------------ (2)

Equation (2):
L + W = 6
L = 6 - W -------------- Sub into (1)
(6 - W) W = 8
6W - W² = 8
W² - 6W + 8 =0
(W -2 )(W - 4) = 0
W = 2 or 4

When W =2, L = 6 - 2 = 4
When W = 4, L = 6 - 4 = 2

Answer: The Width is 2 cm and the Length is 4 cm

Answer:

y = -1/2 x + 1

Step-by-step explanation:

(-2, 2) and (4, -1) are points of the linear function, that will be described as:

y = ax + b

setting x=-2, y=2:

2 = -2a + b, so b = 2 + 2a

setting x=4, y=-1:

-1 = 4a + b ⇒ -1 = 4a + 2 + 2a ⇒ -3 = 6a ⇒ a = -1/2, b = 1

y = -1/2 x + 1

A radio signal travels at 3.00 • 10^8 meters per second. How many seconds will it take for a radio signal to travel from a satellite to the surface of Earth if the satellite is orbiting at a height of 3.54 • 10^7 meters? Show your work.would the answer be rate=3*10^8m/s
distance=3.6*10^7m
time=distance/rate=3.6/30 ???

Answers

The answer is 0.118 seconds.

The velocity (v) is the distance (d) divided by time (t):
v = d ÷ t

It is given:
v = 3.00 × 10⁸ meters per second
d = 3.54 × 10⁷ meters

It is unknown:
t = ?

If:
v = d ÷ t
Then:
t = d ÷ v
t = 3.54 × 10⁷ meters ÷ 3.00 × 10⁸ meters/second
t = 1.18 × 10⁻¹ seconds
t = 0.118 seconds

Therefore, radio signal will travel from a satellite to the surface ofEarth 0.118 seconds.

Which is equal to 42 • 48?
a. 416
b. 410
c. 46
d. 4−6

Answers

Answer:

$4^(-6)$

Step-by-step explanation:

Given : $4^2 / 4^8$

To Find :Which is equal to $4^2 / 4^8$ ?

a. $4^(16)$

b. $4^(10)$

c. $4^6$

d. $4^(-6)$

Solution:

$4^2 / 4^8$

Property : $a^x / a^y = a^(x-y)$

Using the property :

$4^(2-8)$

$4^(-6)$

So, $4^2 / 4^8$ = $4^(-6)$

Answer: angle AOB = 40 degrees

====================================================

Explanation:

The smaller angles AOB and BOC combine to the largest angle AOC

By the angle addition postulate, we can say,

(angleAOB) + (angleBOC) = (angleAOC)

(3x+4) + (8x-28) = 108

11x-24 = 108

11x = 108+24 .... adding 24 to both sides

11x = 132

x = 132/11 .... dividing both sides by 11

x = 12

We can use this x value to find each angle

angle AOB = 3x+4 = 3*12+4 = 40 degrees

angle BOC = 8x-28 = 8*12-28 = 68 degrees

As a check,

(angleAOB)+(angleBOC) = (40)+(68) = 108

which matches with the measure of angle AOC. This confirms our answers.

Answer:

$AOB = 40$

Step-by-step explanation:

$AOC = 108 \n </p><p>AOB = 3x + 4 \n </p><p>BOC = 8x - 28 \n but \: AOB +BOC =AOC \n 3x + 4 + 8x - 28 = 108\n 11x = 132 \n x = 12\n AOB = 3x + 4 = 3(12) + 4 \n AOB = 40$
