Anthony buys a guitar for $80. What is the final price he pays after an 8% sales tax?

Answers

Answer:

$86.4

Step-by-step explanation:

You already know that Anthony spent $80 on a guitar and has to pay 8% sales tax so you have to find 8% of $80 and add it to $80 because that is how much he has to pay. 8% of 80=6.4. 6.4+80=86.4 so that is how you get your answer.

What is the value of x?

Answers

Answer: x = 140 degrees

Steps:
360 = 40 + 40 + x + x
360 = 80 + x + x
360 = 80 + 2x
360 - 80 = 2x
280 = 2x
280/2 = x
140 = x

Check:
x = 140
40 + 40 + x + x
40 + 40 + 140 + 140 = 360
360 = 360 ✅

The lifetime for a certain brand of widgets is normally distributed. A random sample of 25 widgets is taken and a sample mean lifetime of 520 hours with a standard deviation of 50 hours. Before taking the sample, researchers claimed that the mean lifetime of a widget was more than 500 hours. 1. null hypothesis:
2. the alternative hypothesis:
3. explain what test will be used and why?

Answers

Answer:

1. H0: u = 500

2. H1: u <500

3. One sample t test

Step-by-step explanation:

1. The null hypothesis in this question would be

H0: u = 500

2. The alternative hypothesis would be

H1: u < 500

3. The test that we are going to be using is the one sample t test. This test is used to test hypothesis. It would make a comparison of h0 to the mean of the sample. Now we are using this here because the sample standard deviation was given

In the figure below, the triangles are similar. Find the ratio of their areas from larger to smaller.

Answers

Area of larger triangle is A1
21:14=x:8
x=21•8/14
x=168/14
x=12
x=base of triangle
A2=h•b/2
21^2=6^2+h^2
441=36+h^2
h^2=441-36
h^2=405
h= √405
h=20.12

A1=12•20.12/2
A1=6•20.12
A1=120.72


Area of smallest triangle is A2
A2=b•h/2
h=?
14^2=4^2+h^2
196=16+h^2
h^2=196-16
h^2=180
h= √180
h=13.42
A2=8•13.42/2
A2=4•13.42
A2=53.68

Ratio 120.72:53.68
Ratio=2.25

At 10AM the temperature
was -15°F and rising by 2
degrees each hour. What
would the temperature be
by 5PM?

Answers

Answer:-1 °F

Step-by-step explanation:

Answer:

-1°F

Step-by-step explanation:

10AM = -15

11AM = -13

12AM = -11

1PM = -9

2PM = -7

3PM = -5

4PM = -3

5PM = -1

or 10AM to 5PM is 7 hours and 2*7 = 14, so them -15 + 14= -1

An equilateral triangle has a side length of 1.4x + 2 inches
. A regular hexagon has
a side length of 0.5x + 2 inches. The perimeters are equal. What is the side length
of the triangle? What is the side length of the hexagon? Show your work.

SOLUTION

Answers

Answer:

The Perimeter of an equilateral triangle = 1.4x+2+1.4x+2+1.4x+2

                                                                  = 4.2x+6

The Perimeter of a regular hexagon = 0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2+0.5x+2

= 3x+12

Given that the perimeters are equal

4.2x+6 = 3x+12

4.2x - 3x = 12-6

1.2x = 6

x = 6/1.2

x=5

The side length of the triangle = 1.4x+2

                                                   = 1.4 (5) +2

                                                   = 9 inches

The side length of hexagon = 0.5x+2

                                              = 0.5(5) +2

                                              = 4.5inches

Answers

Answer:

50+P=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

P=125-50=75°

q+125=180 linear pair

q=180-125=55°

r=q=55° vertically opposite angle

s+85=125 exterior angle of the triangle is equal to the sum of two opposite interior angle

s=125-85=40°

s+t=180 linear pair

t=180-40=140°

u=s=40° vertically opposite angle

w=65° vertically opposite angle

v+u+w=180 sum of interior angle of the triangle is 180

v+40+65=180

v=180-105=75°

x+65=180 linear pair

x=180-65=115°
