Answer:

$115

Step-by-step explanation:

The cost of the labor per hour is $115.

The total amount that the technician charged her is the sum of the cost for the total hours worked and the costs of the parts.

Total charge = cost of total hours worked + cost of parts

$749 = $59 +  cost of total hours worked

Cost of total hours worked = $749 - $59

Cost of total hours worked = $690.

Answer:

8. P = 48 cm A = 83

9. P =32 cm A = 60

Step-by-step explanation:

P = add all sides together

A = base times height

Answer:

8. P = 48 cm, A = 83 cm²

9. P = 36 cm, A = 56 cm²

Step-by-step explanation:

The trick with irregular shaped objects areas is to split them up into several rectangles. Perimeters is just filling in the missing sides using the other sides and adding them all up.

After finding the missing sides for the first figure, the perimeter would be:

5 + 10 + 4 + 3 + 11 + 3 + 2 + 10 = 48 cm

For the area, we split the figure into the vertical rectangle on top and the horizontal rectangle on the bottom. You'll see that the vertical rectangle has an area of 50 squared cm (5 * 10), while the area of the other rectangle is 33 squared cm (3 * 11), so the area of the whole figure is 50 + 33 = 83 squared cm.

Use this same method for the next figure, and you should get that the perimeter is 36 cm and the area is 56 squared cm.

Solving :

Answer:

The clock face is divided into sixty equal parts, each minute. The minute hand is located on the 20 minute mark at 6:20, the hour hand located between the 30 minute mark and the 35 minute mark. When the minute hand goes all sixty minutes, the hour hand only moves five, so to figure out the location of the hour hand, we look at how much the hour has progressed, in this case 20 minutes, or one third of the hour. So the minute hand has moved one third of the way through the hour, so has the hour hand moved one third of the way through the five minutes, or, five thirds of a minute, which is one and two thirds minute, one minute forty seconds. That puts the hour hand at thirty minutes plus one minute and forty seconds—at 31min 40sec—which is 11min 40sec farther than the minute hand.

Answer:

x= 14

Step-by-step explanation:

When the triangles are similar, they should have a similar ratio that makes one side equal to another. In this case, the ratio is 1.5 as 24 divided by 16 is 1.5. Now, taking the side that is "similar" to the x-value which is 21, we divided 21 by 1.5 resulting in x= 14.

Answer:

x = 14

Step-by-step explanation:

24/21 = 1.14285714286

16/14 = 1.14285714286

A: Yes, the sum of two sides are greater than the third side.

B: Yes, the sum of two sides are greater than the third side. (Would be an equiilateral triangl.)

C: No, the sum of two sides are less than the third side.

In general, To determine if 3 side lengths are a triangle, use the triangle inequality theorem, which states that the sum of 2 sides of a triangle must be greater than the third side. Therefore, all you have to do is add together each combination of 2 sides to see if it's greater than the third side.

Volume is a three-dimensional scalar quantity. The amount of coffee that can be put in the tumbler is 11.486 in³.

A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.

Given the diameter of the coffee, the tumbler is 3inches, while the height is 7 inches, also, 0.5 inches is needed to be left to fit the lid on the top. Therefore, the height of the tumbler will be 6.5 inches (7-0.5).

Now, the volume of the coffee tumbler will be,

The volume of the coffee tumbler = (π/4)×D²×h

                                                         = (π/4)×(1.5)²×6.5

                                                         = 11.486 in³

Hence, the amount of coffee that can be put in the tumbler is 11.486 in³.

Answer:

C) y = 16 feet

Step-by-step explanation:

the corresponding sides in ABCD are equal to their corresponding sides by EFGH multiplied by something

all values are in feet

let x represent the unknown side in ABCD

ABCD lengths in order: x, 30 , 40 , 60

let a and b represent the unknown sides in EFGH

EFGH lengths in order: 6, 12, a, b

thus, 30 corresponds to 12 as they are both the second shortest sides

corresponding side in EFGH * something = corresponding side in ABCD

12 * something = 30

let something be r

12 * r = 30

divide both sides by 12 to isolate r

r = 30/12

thus, to get a side in ABCD, we multiply the corresponding side in EFGH by 30/12

we want to find the second longest side in EFGH. the corresponding side to that in ABCD is 40, as 40 is the second longest side in ABCD

let the second longest side in EFGH = y

y * 30/12 = 40

multiply both sides by 12/30 to isolate y

40 * 12 / 30 = y = 16

y = 16 feet

Answer:

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x be the measure of the second leg , then

x² + 15² = 19²

x² + 225 = 361 ( subtract 225 from both sides )

x² = 136 ( take square root of both sides )

The equation for the path of a launched projectile contains the vertex (5, 120) and the point (25, 80) on the boundary is shown in the graph.

It is defined as the graph of a quadratic function that has something bowl-shaped.

The path of the launched projectile will a parabola.

We have the vertex of the parabola (5, 120)

The standard equation in terms of vertex (h, k)

[tex]\rm y = a(x-h)^2+k[/tex]

Plug the points:

[tex]\rm y = a(x-5)^2+120[/tex]

To find the value of “a” plug point (25, 80)

[tex]\rm 80 = a(25-5)^2+120[/tex]

a = -1/10

Plug this into the equation;

The path of the equation:

[tex]\rm y = \dfrac{-1}{10}(x-5)^2+120[/tex]

Thus, the equation for the path of a launched projectile contains the vertex (5, 120) and the point (25, 80) on the boundary is shown in the graph.

The lower bound of the confidence interval is 0.55.

A confidence interval for a proportion is a range of values that is likely to contain a population proportion with a certain level of confidence.

Construct a confidence interval of the population proportion at the given level of confidence x equals = 540, n equals = 900, 96% confidence.

The value of p is;

[tex]\rm p=\dfrac{x}{n}\\\\p =\dfrac{540}{900}\\\\p=0.6[/tex]

The standard error of the proportion is:

[tex]\rm \sigma_p=\sqrt{\dfrac{p(1-p)}{n}} \\\\ \sigma_p=\sqrt{\dfrac{0.6(1-0.6)}{540}} \\\\ \sigma_p=\sqrt{\dfrac{0.6\times 0.4}{540}} \\\\ \sigma_p=\sqrt{\dfrac{0.24}{540}} \\\\ \sigma_p=\sqrt{0.00044}\\\\ \sigma_p=0.02[/tex]

The critical z-value for a 94% confidence interval is z = 2.04

The margin of error (MOE) can be calculated as:

[tex]\rm Margin \ of \ error=\sigma_p \times z =2.04 \times0.02 =0.04[/tex]

Then, the lower bound of the confidence interval is;

[tex]Lower \ bound =p-x\times \sigma_p=0.6-0.04=0.55[/tex]

Hence, the lower bound of the confidence interval is 0.55.

  D) 80%

Step-by-step explanation:

To find the fraction of women surveyed who prefer salads, we need to know something about how many were surveyed, and how many of those preferred salads.

For this purpose, we can effectively ignore the percent signs in the table, and consider that it represent 100 people surveyed.

__

Of the 100 people surveyed, 40 were women. Of the 40 women, 32 preferred salads. That is, 32/40 = 8/10 = 80% of the women surveyed preferred salads.

_____

Additional comment

When dealing with percentages, one must always keep in mind the base the percentage is referring to. For all of the numbers in the table, the base is the total number of participants in the survey.

For the percentage that is the answer to the question, the base is the number of women surveyed (or something proportional to that number).

Answer:

x = 15,  45 degree angle

Step-by-step explanation:

2x + 15 and 6x - 45 adds up to 90 degrees

(2x + 15) + (6x - 45) = 90

combine like terms:

2x + 6x = 8x

15 + (-45) = -30

8x - 30 = 90

8x - 30 + 30 = 90 + 30

8x = 120

8x / 8 = 120 / 8

x = 15

2(15) + 15

30 + 15 = 45 degree angle

6(15) - 45

90 - 45 = 45

Answer:

x = 15.

Step-by-step explanation:

The figure is a square so opposite sides are congruent and parallel.

The 2 angles marked are interior alternate angles, so they are congruent.

Therefore:

2x + 15 = 6x - 45

15 + 45 = 6x - 2x

4x = 60

x = 15.
