Answer:

7*(4 + 7)

Step-by-step explanation:

49 = 7 * 7

GCF = 7

28 + 49 = (7*4) + (7*7)

= 7*(4 + 7)

The arc length formula is :

where r = radius and the angle is in radians

From the problem, the arc length is 21π units and the radius is 15 units.

Using the formula above :

ANSWER :

A.

Answer:

To the nearest tenth, the length is 6.4 meters, and the width is 3.4 meters.

Step-by-step explanation:

Let w be the width of the rectangle. Then l = w + 3, and we have:

[tex] w(w + 3) = 22[/tex]

[tex] {w}^{2} + 3w = 22[/tex]

[tex] {w}^{2} + 3w - 22 = 0[/tex]

Calculating the discriminant:

[tex] \sqrt{ {3}^{2} - 4(1)( - 22)} = \sqrt{9 + 88} = \sqrt{97} [/tex]

So by the quadratic formula, and discarding the negative solution, we then obtain:

[tex]w = \frac{ - 3 + \sqrt{97} }{2} = 3.4[/tex]

[tex]l = w + 3 = 3.4 + 3 = 6.4[/tex]

Answer:

a = 9

Step-by-step explanation:

[tex]a^{2}[/tex] = a*a

a = -3

-3 * -3 = 9

NOTE: 2 negative numbers multiplied by each other always equals a positive

So.... a = 9

Katie's hair is (17x/4 +3) inches long when she leaves the barber shop.

According to the question,

We have the following information:

Katie’s hair is 4 ½ x + 1 inches long.

The barber cuts ¼ x – 2 inches off her hair.

Now, the remaining length of her hair will be obtained by subtracting the length of hair cut from the original length.

So, we have the following expression:

([tex]4\frac{1}{2} x+1[/tex])-(x/4-2)

9x/2+1-x/4+2

9x/2-x/4+3

Taking 4 as the least common factor:

18x-x+12/4

17x+12/4

17x/4 + 12/4

17x/4 + 3 inches

Hence, Katie's hair is (17x/4 +3) inches long when she leaves the barber shop.

We have a linear model, that relates temperature with altitude.

The first senctence gives us a clue about tha rate of change (the slope) of temperature in function of the altitude.

We can write the slope, in °F/1000 ft, as:

The temperature on the ground, where h=0, is 56.9 °F, so we can write the equation of the line as:

When the altitude is 8,000 ft, h=8 and T is:

The temperature at 8,000 ft will be 47.3 °F.

Step 2

Using the elimination method.

Hence,

Answer;

The system of inequalities for the given situation is

x +y ≤ 70.

$4x +  $8x ≤ $400.

y ≤ 50.

And one possible solution is (40,30) and the graph of the inequality is attached below.

Inequality:

Inequality refers the non equal comparison of the expressions.

Given,

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $4 and each adult ticket sells for $8. The auditorium can hold a maximum of 70 people. The drama club must make no less than $400 from ticket sales to cover the show's costs. Also, they can sell at most 50 adult tickets.

Here we need to find the system of inequalities graphically and also determine one possible solution for it.

Let us consider x represents the number of student tickets sold and y represents the number of adult tickets sold.

Therefore, in here we know that, they can sell at most 50 adult tickets.

Which means that the value of y can't be greater than 50.

So, in inequality it can be written as,

y ≤ 50.

And the total number of seats in the auditorium is 70.

Therefore,

x + y ≤ 70

And we also know that, they sells the ticket at the cost not less than $400.

So,

$4x +  $8x ≤ $400.

Now, we have to plot those inequality on the graph, the we get he following graph.

In the graph, the blue line represents the inequality x + y ≤ 70 and the red line represents the inequality $4x +  $8x ≤ $400.

While we looking into the graph we have identified that the solution of the graph is (40,30).

Which means there are 40 number of students and 30 number of adults.

Step-by-step explanation:

The first box is m, which is the slope. To find the slope you do rise over run, so basically the change in x and y. You move up 5 and over 2, so m would be 5/2.

The second box is b, which is the y-intercept. To find the y-intercept, you just find where the line crosses the y-axis. That would be 5

a. The scale that is being used for the image is: 1 inches to 6 inches or 1 inches = 6 inches.

b. The actual book is 18 inches tall.

An image is the new figure formed when an original figure is dilated, either by enlargement or by reduction. The image is a similar figure to the preimage (original figure).

Given the following:

a. The scale being used = width of image : width of preimage (actual book)

Scale = 1.5 : 9

Scale = 1 : 6

Answer:

Joanne should definitely purchase the first one because it is much cheaper.

Step-by-step explanation:

So, to find the cost of each washing machine, we can simply turn the percentages into decimals and multiply to get our answer. Let's start with 40%. We bring the decimal back to spaces to get: 0.40. Then, we multiply it from the $390, because 40% 'of' means multiply:

0.40 x 390 = $156.

390 - 156 = $234

Now, the next one:

0.10 x 390 = $39

390 - 39 = $351

Then, we take 351 dollars and find the 30% off difference.

0.30 x 351 = 105.30

390 - 105.3 = $284.70

The formula for finding slope is expressed as

slope = (y2 - y1)/(x2 - x1)

where

y2 and y1 are final and initial values of the y coordinates respectively

x2 and x1 are final and initial values of the x coordinates respectively

Considering line PQ,

x1 = - 6, y1 = 16

x2 = 2, y2 = - 4

Slope = (- 4 - 16)/(2 - - 6) = - 20/8

Slope = - 2.5

Considering line RS,

x1 = - 6, y1 = 14

x2 = - 2, y2 = 4

Slope = (4 - 14)/(- 2 - - 6) = - 10/4

Slope = - 2.5

If the slope of two lines are equal, it means that they are parallel. We can see that the slopes of PQ and RS are equal. Thus,

Line PQ is parallel to line RS

The △ABC is congruent to triangle △ADE (△ABC ≅ △ADE) under (B) SAS condition.

Two triangles are said to be congruent if all three corresponding sides and all three corresponding angles have the same size.

You can move, flip, twist, and turn these triangles to produce the same effect.

So, first label the two triangles as △ABC and △ADE.

Now, to prove that △ABC ≅ △ADE:

BA = DA  (Given)

AC = ED  (Given)

∠BAC = ∠ADE (Since, both lines are similar, so the angle between them will also be soililar and congruent.

So, we can say that △ABC ≅ △ADE is under SAS conditions.
