Mrs. Allen a high school teacht is grading quizzes and tests this weekend she has at most 4 hours or 240 minutes to spend grading and she would like to get at least 60 quizzes and tests graded on average it takes her 3 minutes to grade each quiz and 8 minutes to grade each test
Answers
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).

Answers
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

Susan is 5.5 ft tall and casts a shadow that it is 4 ft long on the ground. She is walking through a park and finds the shadow of a sculpture is 16 ft long. How tall is the sculpture?
Answers
Answer:
22 ft
Step-by-step explanation:
Height of Susan/Length of shadow = Height of sculpture/Length of Shadow of sculpture
5.5 ft/4 ft = x/16ft
Cross Multiply
4 × x = 5.5 × 16
x = 5.5 × 16/4
x = 22 ft
The height of the sculpture is 22 ft

WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)
Answers
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]

If a 30 foot ladder is positioned so that the bottom of the ladder is 1/4 of its length away from the wall, what angle does the ladder make with the ground
Answers
Answer:
[tex]75.52^\circ[/tex]
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]

Vanessa works 32 hours per week at her job. Her boss offers her a full time job (40 Hours per week) and a 2 dollar per hour raise. She says "this is great now I'll make 200 more per week". What is Vanessa's hourly wage before the raise?
Answers
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
