Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

[tex]8=\frac{4}{3}(-4)+b[/tex]

After solving the equation, b will equal -16/3 making the final equation be

[tex]y=\frac{4}{3} x-\frac{16}{3}[/tex]

Using the equation, you can solve for r.

[tex]12=\frac{4}{3} x-\frac{16}{3}[/tex]

This will bring the answer being r = 13

Step-by-step explanation:

Given that:

The length of the ladder = 30 ft

Distance between bottom of ladder and wall = [tex]\frac{1}{4}^{th}[/tex] of its length

To find:

Angle made between the ladder and ground = ?

Solution:

This situation can be compared with a right angled [tex]\triangle ABC[/tex] as shown in the attached image in the answer area.

Side AC being the hypotenuse has the ladder along it.

AB is the wall.

BC is the distance between the wall and foot of ladder.

Formula for cosine trigonometric ratio:

[tex]cos\theta = \dfrac{Base}{Hypotenuse}[/tex]

In [tex]\triangle ABC[/tex]:

[tex]cosC=\dfrac{BC}{AC}[/tex]

Putting the values:

[tex]BC=\dfrac{AC}{4}[/tex]

[tex]cosC=\dfrac{\frac{AC}4}{AC}\\\Rightarrow cos C = \dfrac{1}{4}\\\Rightarrow \angle C = cos^{-1}(0.25)\\\Rightarrow \angle C =\bold{75.52^\circ}[/tex]

Answer:

175

Step-by-step explanation:

Hi! Nice to meet you and have a great day.

Answer:

The answer is B.

Step-by-step explanation:

Answer:

10) 9x - 2° = 5x + 54° (corresponding angles are equal)

9x - 5x = 54 + 2

4x = 56

x = 56/4

x = 14°

10y + 6° = 9x - 2° (linear pair)

10y + 6° = 9(14)° - 2°

10y + 6° = 126° - 2°

10y + 6° = 124°

10y = 124° - 6°

10y = 118

y = 118/10

Answer:

1/4 of the pizza.

Step-by-step explanation:

Since there are 2 people, you would want to divide 2/4 by 2. 2/4*1/2 = 1/4, so your answer is 1/4.

Answer:

24 hours

Step-by-step explanation:

set up a ratio:

12 miles = 16 hours

-------------    ------------

18 miles =   x hours

cross multiply

12m * x = 16h * 18 m

solve for x

x=16h * 18m / 12m = 24 hours

Answer:

C 1 1/3 I got it right in the quiz

Answer:

(55,9)

Step-by-step explanation:

Write one inequality to represent the number of quizzes and tests Mrs. Allen must grade and one inequality to represent the number of minutes it will take her to grade the quizzes and tests.

Mrs. Allen must grade at least 60 quizzes and tests, so the sum of x and y must be greater than or equal to 60.

On average, it takes Mrs. Allen 3 minutes to grade each quiz and 8 minutes to grade each test. So, the total number of minutes it takes her to grade x quizzes is 3x minutes, and the total number of minutes it takes her to grade y tests is 8y minutes. Since she has at most 240 minutes to spend grading, the sum of 3x and 8y must be less than or equal to 240.

The solution set to the system of these linear inequalities represents the numbers of quizzes and tests Mrs. Allen can grade this weekend.

Now, consider each of the coordinate points. In order to be a solution to this system of inequalities, both inequalities must be satisfied by the values of x and y. When x = 55 and y = 9, both inequalities are satisfied. To confirm, substitute these values of x and y into the first inequality.

Now substitute the values into the second inequality.

Therefore, the only point that lies in the solution set is (55,9).

Answer: 7

Step-by-step explanation: This is an equalateral triangle. You can tell by the marks on each angle, marking that they are equal.

This means that the two sides that aren't the hypotenuse are the same.

Therefore,

[tex]4(x+2) = 36[/tex]

Multiply out the 4

[tex]4x + 8 = 36[/tex]

Subtract 8

[tex]4x = 28[/tex]

Divide by 4

[tex]x = 7[/tex]

Answer:

Hey there !

Solution:

Let the number be x

=> x + 2x² = 10

=> 2x² + x - 10 = 0

Factorising the quadratic equation we get,

=> 2x² + 5x - 4x - 10 = 0

=> x ( 2x + 5 ) -2 ( 2x + 5 ) = 0

=> ( x - 2 ) ( 2x + 5 ) = 0

=> x = 2, -5/2

Since x is a whole number, -5 / 2 wont be applicable.

Hence x = 2.

Hence the number is 2.

Answer: C. (1,1)

Step-by-step explanation:

Midpoint

Given a segment defined by points (x1,y1) and (x2,y2), the midpoint (xm,ym) is calculated as follows:

[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]

The endpoints are (-2,-4) and (4,6).

Calculating the midpoint:

[tex]\displaystyle x_m=\frac{-2+4}{2}=\frac{2}{2}=1[/tex]

[tex]\displaystyle y_m=\frac{-4+6}{2}=\frac{2}{2}=1[/tex]

The midpoint is (1,1).

Answer:

Step-by-step explanation:

Answer:

$35.75 per hour

Step-by-step explanation:

In order to calculate this, we first need to calculate how much she made with her current hourly wage. We do this by multiplying the hours she worked by her current hourly wage plus her raise.

32 hours * (40+2) = $1,344

Now we subtract $200, since this is how much more she is making with her raise, and then we divide that amount by the 32 hours she is working per week.

(1,344 - 200) / 32 = $35.75 per hour

Finally, we can see that Vanessa's hourly wage before the raise was $35.75 per hour
