Answer 1

Answer:

100.32

Step-by-step explanation:

First, we have to find 14% of 88
14% of 88 is = 88 x 14/100
                   = 12.32

Now we have to increase the number 88 by 14%, which means we have to add 14% of 88 (12.32) to the given number (88)  

88 + (14% of 88)

= 88 + 12.32

=100.32

Which fraction below represents a terminating decimal?
A.
B.
C.
D.

Answers

Answer:

3/10

Step-by-step explanation:

The fraction, 1/12, can be written as 1/4 * 1/3. Since we know that 1/3 = 0.333333... and it doesn't terminate, we know that 1/12 doesn't terminate. Similarly 2/9 = 2/3*1/3 and 2/3 = 2*1/3, and neither of these fractions terminate. But, when dividing 3/10, you get 0.3, which terminates.

Grayson spots an airplane on radar that is
currently approaching in a straight line,
and that will fly directly overhead. The
plane maintains a constant altitude of
7225 feet. Grayson initially measures an
angle of elevation of 19 to the plane at
point A. At some later time, he measures
an angle of elevation of 39° to the plane at
point B. Find the distance the plane
traveled from point A to point B. Round
your answer to the nearest tenth of a foot
if necessary.

Answers

Using the slope concept, it is found that the distance traveled from point A to point B was of 12060.8 ft.

What is a slope?

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

At point A, the vertical change is of 7225 feet, with an angle of 19º, hence:

[tex]\tan{19^\circ} = \frac{7225}{x_A}[/tex]

[tex]x_A = \frac{7225}{\tan{19^\circ}}[/tex]

[tex]x_A = 20982.9[/tex]

At point B, the vertical change is of 7225 feet, with an angle of 39º, hence:

[tex]\tan{39^\circ} = \frac{7225}{x_B}[/tex]

[tex]x_B = \frac{7225}{\tan{39^\circ}}[/tex]

[tex]x_B = 8922.1[/tex]

The distance in feet is given by:

[tex]d = x_A - x_B = 20982.9 - 8922.1 = 12060.8[/tex]

Mrs. Miller is measuring fabric for costumes for the school's musical. She
needs 10.5 meters of fabric. She has 140 centimeters of fabric. How much more
fabric does Mrs. Miller need?

Answers

1 metre is 100 cm so 10.5 metre is 1050 cm 1050 - 140 = 910 so she needs 910 cm or 9.1 m more

Answer:

9.1 meters or 910 centimeters

Step-by-step explanation:

10.5 meters = 1050 centimeters

1050 - 140 = 910 centimeters

Answer:

Equation: y + 1 = -2(x - 0)        OR        y + 3 = -2(x - 1)

Slope: -2

Y-intercept: (0, -1)

Step-by-step explanation:

First, create an equation in point-slope form using ONE point. Using (0,-1):

y - y1 = m(x - x1)

y + 1 = m(x - 0)

Then, use both points to find slope:

[tex]\frac{y2-y1}{x2-x1} =m[/tex]

[tex]\frac{-1-(-3)}{0-1}[/tex]

[tex]\frac{2}{-1}=m=-2[/tex]

Then, plug the slope into the equation and rewrite in the form of y=mx+b:

y + 1 = (-2)(x - 0)

y + 1 = -2x

y = -2x - 1

-1 = b      OR      (0, -1)      

Final answers:

Equation: y + 1 = -2(x - 0)      OR       y + 3 = -2(x - 1)

Slope: -2

Y-intercept: (0, -1)

Solving the System of Equations
Examine the system of equations.

4.2x + 8y = 41.8

–4.2x + y = 19.4

Use the linear combination method to solve the system of equations. What is the value of x?
–3
–1
1.7
6.8

Answers

Answer:

x= -3

Step-by-step explanation:

Solve the following system:

{8 y + 4.2 x = 41.8

y - 4.2 x = 19.4

In the second equation, look to solve for y:

{8 y + 4.2 x = 41.8

y - 4.2 x = 19.4

y - 4.2 x = y - (21 x)/5 and 19.4 = 97/5:

y - (21 x)/5 = 97/5

Add (21 x)/5 to both sides:

{8 y + 4.2 x = 41.8

y = 1/5 (21 x + 97)

Substitute y = 1/5 (21 x + 97) into the first equation:

{4.2 x + 8/5 (21 x + 97) = 41.8

y = 1/5 (21 x + 97)

4.2 x + (8 (21 x + 97))/5 = ((168 x)/5 + 776/5) + 4.2 x = 37.8 x + 776/5:

{(37.8 x + 776/5) = 41.8

y = 1/5 (21 x + 97)

In the first equation, look to solve for x:

{37.8 x + 776/5 = 41.8

y = 1/5 (21 x + 97)

37.8 x + 776/5 = (189 x)/5 + 776/5 and 41.8 = 209/5:

(189 x)/5 + 776/5 = 209/5

Subtract 776/5 from both sides:

{(189 x)/5 = -567/5

y = 1/5 (21 x + 97)

Multiply both sides by 5/189:

{x = -3

y = 1/5 (21 x + 97)

Substitute x = -3 into the second equation:

Answer: {x = -3, y = 34/5

A garden store purchased a lawn mower and marked it up 160% from the original cost of $82.67. A week later, the store placed the lawn mower on sale for 10% off. What was the discount price?

Answers

The discount price of the lawn mower purchased by the store is  $193.45.

What is the discount price?

The first step is to determine the selling price of the lawn mower.

Selling price = ( 1 + 1.60) x $82.67 = 214.94

Now determine the price after the discount has been applied.

Discount price = (1 - 0.1) x 214.94 = $193.45

How to determine the rule of dilation?

The coordinates of C' is given as:

C' = (4.5, 4.5)

The coordinate of point C is not given.

So, I will apply a general rule

The general rule of dilation is:
