-3+3=0

18-3=15

0/15 = 0

slope=0

the coordinates of point c is (9/2, -3/2)

The original coordinate = C(6, -2)

scale factor r =3/4

New coordinate (c) = scale factor × the original coordinate

c = 3/4(6, -2)

c = (3/4×6, -2×3/4)

c = (18/4, -6/4)

c = (9/2, -3/2)

Hence, the coordinates of point c is (9/2, -3/2)

Answer:

The well-desgined graph has an appropriate scale for the y-axis. By appropriate we mean that the scale is such that all points on the graph can be discerned easily. In other words, the scale is not too wide or too narrow.

For graph A, the scale is such that the data points are at such a distance from each other that their values can be easily read off. On the other hand, for graph B, there isn't enough vertical distance between the data points for them to be easily read.

The width of the plywood = 23/8 ft

The two rectangular pieces of plywood had equal widths.

The length of first rectangular piece = 6 ft

The length of second rectangular piece = 5 1/2 ft = 11/2 ft

The two pieces are joined to make a single rectangular stage.

Then the total length of the stage = 6 + 11/2 = 23/2 ft

Now area of the rectangular stage = 66 1/8 = 529/8 square feet.

⇒ length x width = 529/8

⇒ 23/2 x width = 529/8

⇒ width = 529/8 x 2/23 = 23/4 ft

Let 'x' be the width of a rectangular plywood.

Then 2x = width of the stage

⇒ 2x = 23/4

⇒ x = 23/8 ft

Hence width of the plywood = 23/8 ft

ANSWER:

The result of the expression 3x-(2x+10) for x = [tex]7\frac{5}{13}[/tex] is -2.61

The expression is

3x-(2x+10)

The expression is the mathematical sentence with a minimum of two variables and at least one math operation.

The value of the x = [tex]7\frac{5}{13}[/tex]

Convert the mixed fraction to the simple fraction

[tex]7\frac{5}{13}[/tex] = 96/13

Convert the simple fraction to the decimal form

96/13 = 7.39

Substitute the value of x in the given expression 3x - (2x + 10)

= 3 × 7.39 - (2×7.39 + 10)

Multiply the terms first

= 22.17 - (14.78 + 10)

= 22.17 - (24.78)

= -2.61

Hence, the result of the expression 3x-(2x+10) for x = [tex]7\frac{5}{13}[/tex] is -2.61

Using properties of exponents, it is found that Mia's first mistake is described as follows:

Mia made a mistake in Step 3. She simplified the exponents 16 and -8 incorrectly. She should have subtracted them.

When two terms with the same base and different exponents are multiplied, we keep the base and add the exponents, as follows:

3^0 x 3^(16) = 3^(0 + 16) = 3^16.

Hence the Step 1 is correct.

For the power of power rule, we keep the base and multiply the exponents, hence:

(3^(-4))² = 3^(-4 x 2) = 3^(-8).

Hence the Step 2 is correct.

When two terms with the same base and different exponents are divided, we keep the base and subtract the exponents, as follows:

3^16/(3^(-8)) = 3^(16 - (-8)) = 3^(16 + 8) = 24.

Which is Mia's mistake, as she did not subtract the exponents.

The steps are missing and are given by the image at the end of the answer.

The distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles using the estimation concept.

As per the question statement, Noor’s family is meeting her grandparents at a restaurant and the restaurant is 24.5 miles from Noor’s house but this is 65.5% of the distance from Noor’s house to her grandparents’ house.

We are supposed to find the distance between Noor's house and her grandparent's house. We will use the concept of estimation.

Distance between Noor's house and restaurant = 24.5 miles

Let distance between Noor's house and her grandparent's house be "x" miles.

So the distance between grandparent's house and restaurant = x - 24.5

Now it is given that 24.5 miles is 65.5% of the distance from Noor’s house to her grandparents’ house.

So, 65.5% of x = 24.5

(65.5*x)/100 = 24.5

65.5*x = 2450

x = 2450 / 65.5

x = 37.40 miles

If rounded off to the nearest tenth mile, we get

x = 40 miles.

So, the distance between Noor's house and her grandparent's house is 37.40 miles or if rounded off to the nearest tenth, it will be 40 miles.

With the concepts of percentages and calculations, the percent decrease in the number of people who went to the pool over these four weeks is 10%

Take the base as 100 and convert the percentage to numbers and then proceed with the same.

Now, the initial number of people in the local swimming pool is 1020, after which 100 fewer went, hence 920 people

Now, 135 people more people need to be added, thus 1055 people.

Now, 137 fewer people went, so 918 people went to the pool in the four weeks.

Therefore percent decrease = Difference/No. of people in the first week * 100

Thus, the percent decrease =  102/1020*100=10%

Hence 10% of people went less in the fourth week as compared to the first week.

Terry bought 2 shirts for $14 each.

That is $28 on shirts

2 pair of socks for $2.99

That is $5.98 on socks

A pair of slacks for $25

The sales tax rate is 6.5% or 6.5/100 or 0.065

We want to know how much he paid.

Adding all the items he bought together, we have:

$28 + $5.98 + $25

= $58.98

Next, we apply the sales tax rate.

Take 6.5% of $58.98

This is: $58.98 * 0.065

= $3.83

Finally, add the sales tax with the amount we got

$58.98 + $3.83

= $62.81

He paid $62.81 in total

72, 108, and 108 are the other three angles formed by the two straight lengths of wire.

For the given question.

Two straight lengths of wire are put on the ground, to form vertical angles.

Because vertical angles have always been congruent, 72 is the vertical angle to 72.

Because the line is straight, the answer is 180.

180 - 73 equal 108. (supplement angles)

Because they are both vertical angles, there are two 180s.

The tunnel measures 225 meters in length.

Velocity is the measure of how quickly an object's position changes over time and in relation to a frame of reference. A body moves across space with uniform velocity when it does so with an equal displacement per unit of time.

Velocity is equal to the product of distance and time.

It measures in m/s.

In response to the query, we are provided with the-

150m is the length of the train.

s m is the tunnel's length.

90 km/hr is the train's speed.

= 90 × 5/18 m/sec

= 25m/sec

Total distance equals (train length plus tunnel length).

[tex]Speed = \frac{Distance}{Time}[/tex]

⇒ 25 = (150 + s) / 15

⇒ 25 × 15 = 150 +s

⇒ 375 = 150 + s

⇒ 375 - 150 = s

⇒ s = 225

⇒ s = 225m
