Answers

Answer 1
B 3.5 dollar per hour
Answer 2

Answer:

$3.50 per hour

Step-by-step explanation:

Given : For working 13 hours you earned $45.50 and $94.50 for 27 hours

To Find :What is your rate of pay in dollars per hour?

Solution :

Pay for 13 hours =  $45.50

So, Pay for 1 hour =  [tex]\frac{45.50}{13}[/tex]

Pay for 1 hour =  [tex]3.50[/tex]

So, rate is $3.50 per hour

So, Option B is true

Hence rate of pay in dollars per hour is $3.50 per hour

Carson’s estimate for the cost of tiling his bathroom floor is $25 plus $5 per square foot. He says that he can model the cost with a linear function. Is Carson correct? Why or why not?

Answers

Carson is correct.
 Let's write the variables first.
 Let:
 x = number of square feet of the bathroom floor.
 y = total cost in $.
 The function that best suits the problem is:

Joe can buy a pair of canvas shoes for $7 or a pair of leather shoes for $35. At these prices, what is the ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes?

A. 1/10
B. 1/5
C. 2/5
D. 2/15
E. 3/10

Answers

Final answer:

The ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes is D. 2/5.

Explanation:

To find the ratio of the cost of 6 pairs of canvas shoes to the cost of 3 pairs of leather shoes, we need to calculate the total cost of each option.

For 6 pairs of canvas shoes, the cost is $7 per pair, so the total cost is 6 x $7 = $42.

For 3 pairs of leather shoes, the cost is $35 per pair, so the total cost is 3 x $35 = $105.

Therefore, the ratio is $42 : $105, which simplifies to 2/5.

Answers

The area of the square is s×s

The area of a quarter circle is (πr²)/4
    = 3.14 × 16/4
    = 3.14 ×4
    = 12.56 m²
Therefore, the total area is;

what is the domain of the function y=3sqrt(x)

Answers

y=3sqrt(x)

x≥0

Because every number in the domain must yield real number outputs, set what is in the radical greater than or equal to 0.
ANSWER

The domain of the function

[tex]y = 3 \sqrt{x} [/tex]
is
[tex]x \geqslant 0[/tex]


EXPLANATION


The domain of a function refers to all values of x for which y is defined.



Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.



As soon as the expression under the root sign is less than zero, the function will not be defined.


This means that the square root of a negative number will not be a real number.



Thus the domain is
[tex]x \geqslant 0[/tex]

Two tons of water is pumped into a tank 15 ft. high in 5 minutes. Determine the power output of the pump.

Answers

Answer:

  0.364 horsepower

Step-by-step explanation:

You want to know a pump's power output if it raises 2 tons of water 15 ft in 5 minutes.

Power

The power is conveniently measured in horsepower. One horsepower is 33,000 ft·lb/minute.

Here, we have (2t · 2000 lb/t · 15 ft)/(5 min) = 12000 ft·lb/min

In terms of horsepower, that is ...

  (12000 ft·lb/min) / (33000 ft·lb/min/hp) = 4/11 hp ≈ 0.364 hp

The power output of the pump is about 0.364 horsepower.

__

Additional comment

That's about 271 watts.

The distance dimensions are in feet, so we assume the tons are US short tons of 2000 lb each.

What is 0.673 rounded to the nearest hundredths

Answers

Your answer will be 0.67

Hope this helps

0.673 rounded to the nearest hundredth as 0.67

The digit in the smallest location is unaffected if it is less than 5 in number. Rounding down is the process of reducing a number to zero after a certain number of digits. The digit in the smallest location is added with +1 if it is bigger than or equal to 5.

To round off 0.673 to the nearest hundredth means hundredth digit after decimal, To do so take a look on the thousandth digit after decimal, If it is greater than 5 or equal to 5 increase the hundredth digit after decimal by 1 otherwise no change,

Here, the thousandth digit is 3, 3<5. So, no increment is required.

It will remain as 0.67.

Thus, 0.673 is 0.67 after rounding off to the nearest hundredth.

△ XYZ∼ △ DEF, YZ is 10 meters, ​ XZ ​ is 15 meters, and EF is 8 meters. What is ​ DF?

Answers

im not for sure on this but i would say DF is 13

△ XYZ∼ △ DEF, YZ is 10 meters, ​ XZ ​ is 15 meters, and EF is 8 meters. What is ​ DF?

Solution:

As, △ XYZ∼ △ DEF , so the ratio of sides of triangle is equal.

So, we have, [tex] \frac{XY}{DE} =\frac{YZ}{EF} =\frac{XZ}{DF} [/tex]

Using, [tex] \frac{YZ}{EF} =\frac{XZ}{DF} [/tex]

So, we get,[tex] \frac{10}{8} =\frac{15}{DF} [/tex]

Now, to solve for DF, we must simplify

Simplifying,[tex] \frac{10}{8} =\frac{5*2}{4*2}=\frac{15}{DF) [/tex]

[tex] \frac{5}{4} =\frac{15}{DF} [/tex]

To simplify, Let us multiply by 4*DF on both sides

[tex] \frac{5*4DF}{4} =\frac{15*4DF}{DF} [/tex]

[tex] \frac{5DF}{1} =\frac{15*4}{1} [/tex]

So, 5 DF=15*4=60

To solve for DF, let us divide by 5 on both sides

[tex] \frac{5}{5} DF=\frac{60}{5} [/tex]

[tex] \frac{1}{1} DF=\frac{12}{1} [/tex]

So, DF=12meters

Choose the right answer. If the distance on a map from point R to point T measures 3.0 inches and the scale is 1 inch = 0.5 miles, what is the distance in miles from point R to point T? ______ miles
A. 6.0
B. 3.0
C. 1.5

Answers

The answer is c because when you multiply 3.0 by 0.5 I️t gives you 1.5

Answer: The distance from point R to point T is 1.5 miles.

Step-by-step explanation:

In the map, the scale is,

1 inches = 0.5 miles,

3 inches = 3 × 0.5 = 1.5 miles,

Thus, in the map 3 inches shows 1.5 miles,

Since, in the map, the distance from point R to point P = 3 inches,

Thus, the actual distance from point R to point P = 1.5 miles.

The measures of two of the angles in a triangle are green. Find the measure of the thirs angle. Show your calculations to support your answer.
5-8?

Answers

In a triangle, the three interior angles always add to 180°

5
m∠3 = 180 - 126.5 - 19 = 34.5°

6
m∠3 = 180 - 65.5 - 85 = 29.5°

7
m∠3 = 180 - 98.3 - 37.5 = 44.2°

8
m∠3 = 180 - 31 - 113 = 36°
Angles in a triangle add up to 180°. 
So all we have to do is subtract the 2 angles we know from 180:

For question 5, we subtract 126.5° and 19° from 180°:
180 - 126.5 - 19 = 34.5°

The same principle applies for the rest.

Question 6:
180 - 65.5 -85 = 29.5°

Question 7:
180 -98.3 -37.5 = 44.2°

Question 8:
180 - 31 - 113 = 36°

What are the coordinates of point Q after this reflection

-8,3

-8,-3

-3,-8

8,3

Answers

We have that in this case the point Q is:
 Q = (x, y) = (- 8, 3)
 A reflection of the figure on the x axis is given by the following rule:
 (x, y) ----> (x, -y)
 Applying the transformation:
 (-8, 3) ---> (- 8, -3)
 Answer:
 the coordinates of point Q after this reflection are
 -8, -3

The new coordinates of Q are (-8, -3).

When reflecting a point across the X-axis, the X-coordinate remains unchanged, while the Y-coordinate changes its sign. From the figure attached, we find coordinates of Q are (-8,3). Therefore:

The X-coordinate of Q remains as -8.The Y-coordinate of Q changes from 3 to -3.

As a result, the coordinates of point Q after reflection along the X-axis will be (-8, -3).

Therefore, the new coordinates of point Q are (-8, -3).

The blue figure is a dialation image of the black figure. The labeled point is the center of dilation. Tell wheaten the dilation is a enlargement or a reduction. Then find the scale factor of dilation

Answers

The dilation's scale factor will be 1/4.

The division method is used to divide a bunch of items into equal portions.

Division is the inverse of multiplication. For instance, dividing 20 by 2 means dividing 20 into two equal groups of ten.

Given this,

The blue figure is a magnified version of the black one.

Furthermore, the origin is the center of dilatation.

Now,

Because the blue figure is a dilatation of the black one.

Furthermore, the origin is the center of dilatation.

In this case, the length of the black figure equals 16 units.

Furthermore, the length of the blue figure equals 4 units.

As a result, the dilation scale factor is 4/16.
