Answer 1

Answer:

k=45

Step-by-step explanation:

Since the sum of the measures are 180 and the measures are 45 degrees, k degrees, and 2k degrees, we can conclude that [tex]45+2k+k=180[/tex]. 2k and k are like terms, so you can add 2k and k to get 3k.Then, you would have  [tex]45+3k=180[/tex]. Since you are finding k, you want to isolate k as best you can. To do this, you subtract 45 on both sides [tex]45-45+3k=180 -45 \\3k=135[/tex] as shown by the equation, 180-45 is 135. Then, you divide 3 on both sides to get k=45.

Answer:

x = 54angle ACD = 124°

Step-by-step explanation:

The rule is that the exterior angle (ACD) is equal to the sum of the remote interior angles (the two marked angles on the right).

You are expected to use this relation to write and solve an equation.

  exterior angle = angle D + angle B

  (2x +16) = 58 + (x+12)

  2x +16 = x +70

  x + 16 = 70

  x = 54

Then angle ACD is ...

  angle ACD = (2x +16)° = (2·54 +16)°

  angle ACD = 124°

Alonzo earns 8% commission on vacuum cleaner sales. This past month, Alonzo sold 70 units at $150.00 each. How much did Alonzo make in commissions for the past month?

Answers

Answer:

$840

Step-by-step explanation:

First, multiply 70 by $150 to get the total amount the Alonzo earned

70 x 150 = 10,500

Then, multiply 10,500 by 1.08 to find the total amount made with commissions.

10,500 x 11,340

Finally, subtract 10,500 from 11,340 to find the amount of money earned from commissions.

11,340 - 10,500 = 840

Answer:

$840

Step-by-step explanation:

Start by finding the total profit made:

70 • $150 = $10500

Then multiply the total by the commission rate, %8, which is equal to 0.08:

$10500 • 0.08 = $840

The answer is $840

A ladder is leaning against a house so that the top of the ladder is 12 feet above the ground. The angle the ladder makes with the ground is 51°. How long is the ladder?

12•sin51°
12/cos51°
12•cos51°
12/sin51°
None of these

Answers

Answer:

12/sin5°

Step-by-step explanation:

This angle can be calculated using the law of sine:

sin(angle)=opposite cathete/hypothenuse

sin(angle)=wall/ladder

In this exercise we want to calculate the length of the hypotenuse (ladder), so the equation is changed afterwards.

sin(angle)=wall/ladder

sin(angle)*ladder=wall

ladder=wall/sin(angle)

Now the given values are used:

ladder=wall/sin(angle)

ladder=12ft/cos(51°)

what is 1/10 of 4.8​

Answers

Answer:

0.48

Step-by-step explanation:

Just move back one decimal point of 4.8

Answer: I just did this one lol

Step-by-step explanation:

10 percent *4.8 =

(10:100)*4.8 =

(10*4.8):100 =

48:100 = 0.48

Now we have: 10 percent of 4.8 = 0.48

Question: What is 10 percent of 4.8?

Percentage solution with steps:

Step 1: Our output value is 4.8.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$4.8=100\%$.

Step 4: Similarly, $x=10\%$.

Step 5: This results in a pair of simple equations:

$4.8=100\%(1)$.

$x=10\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{4.8}{x}=\frac{100\%}{10\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{4.8}=\frac{10}{100}$

$ x=0.48$

Write the equation of a line that is perpendicular to y= 3x-2 and that passes through the point (-9,5)

Answers

Answer:

Ans: y = (-1/3)x + 2

Step-by-step explanation:

Perpendicular lines have slopes whose product is -1.  The slope given in

y = 3x - 2

is -3.

The slope of the perpendicular line will be m, and m needs to satisfy the equation

3 * m = -1

Hence m = -1/3.

Our perpendicular line is thus

y = (-1/3)x + b

for some constant b.

We are told that the perpendicular line goes through the point (-9,5).  If so, then the following must hold:

5 = (-1/3)(-9) + b

= 3 + b

b = 2

Ans: y = (-1/3)x + 2

What is the equation of a line perpendicular to y = -5x + 4 that passes through (-10, 6)?

Answers

Answer:  y= 1/5 x + 8

Step-by-step explanation:

To get a perpendicular line, take the reciprocal of the original "m" in the equation and reverse the sign.

- 5 becomes +1/5

Then substitute the y and x values from the given coordinate into the new equation and solve for b

y= mx+b

6=1/5 (-10) + b

6 = -2 +b

8 = b   rewrite the new equation and substitute  8 for b

y= 1/5 x + 8

Jenny and her children went to the SeaWorld.She purchased adult ticket for herself and children tickets for her 2 boys. Tickets cost $39.99 for one adult and $19.99 for each child. Let x represent the number of adult ticket purchase and y represent the number of child tickets purchase. Write an expression to represent the total cost of the tickets Jenny purchased

Answers

Given:

She purchased adult ticket for herself and children tickets for her 2 boys.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

To find:

The expression to represent the total cost of the tickets Jenny purchased.

Solution:

Let x represent the number of adult ticket purchase

and y represent the number of child tickets purchase.

Cost of one adult ticket = $39.99

Cost of one child ticket = $19.99

Total cost = 39.99x + 19.99y

Therefore, the expression for total cost is 39.99x + 19.99y.

She purchased one adult ticket and 2 child tickets.

Substitute x=1 and y=2 in the above expression.

Total cost = 39.99(1) + 19.99(2)

               = 39.99 + 39.98

               = 79.97

Therefore, the required expression to represent the total cost of the tickets Jenny purchased is 39.99(1) + 19.99(2) and total cost is $79.97.

If B is the midpoint of AC, AB = 8x + 2 and BC = 5x + 14, then what is the length of AB?

Answers

Answer:

The length of AB: 34

Step-by-step explanation:

What are we given?

B = Midpoint of AC

AB = 8x + 2

BC = 5x + 14

|--------------|--------------|

A               B               C

(This is what your line would look like)

Our equation would be:

AB + BC = AC

(8x + 2) = (5x + 14)

(AB)      =        (BC)

(Assuming that our line and points are evenly spread out, we can say that they can equal each other)

8x + 2 = 5x  +14

- 5x- 2 = -5x -2

---------------------

3x = 12

[tex]\frac{3x}{3}=\frac{12}{3}[/tex]

---------------------

x = 4

1) Substitute

(8x + 2) + (5x + 14) = AC

    (AB) + ( BC)       = AC

AB = 8(4) + 2

32 + 2

= 34

BC = 5(4) + 14 =

20 + 14

= 34

(We may be able to assume that since the length of the line is possible the same for AB and BC this is considered correct)

The length of the line segment AB is 34 units.

Given that, B is the midpoint of AC, AB = 8x + 2 and BC = 5x + 14.

What is the midpoint of line segment?

A midpoint of a line segment is the point on a segment that bisects the segment into two congruent segments. The midpoint of a line segment is the point on a segment that is at the same distance or halfway between the two ending points.

Since, B is the midpoint of AC

AB=BC

8x + 2=5x+14

Subtract 5x on both sides of the equation, that is

8x+2-5x=5x+14-5x

⇒ 3x+2 = 14

Transpose 2 to other side of the equation, we get

3x = 14 - 2

⇒ 3x=12

Transpose 3 to other side of the equation, we get

x=4

So, AB=8x+2

=8×4+2

=32+2=34 units

Therefore, the length of the line segment AB is 34 units.
