5( q + 27 ) - -30=95

Answer:

(A) 40%

(B) 60%

Step-by-step explanation:

Given:

Total number of cars = 200

Cars in parking lot on Friday = 120

Total number of cars = Total cars on Friday + Total cars on Saturday.

⇒ 200 = 120 + Total cars on Saturday.

⇒ Total cars on Saturday = 200 - 120 = 80

So, 80 cars were in parking lot on Saturday.

(A)

Percentage of cars in parking lot on Friday is given as:

[tex]=\frac{\textrm{Cars in parking lot on Friday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{120}{200}\times 100\\\\=\frac{120}{2}=60\%[/tex]

Therefore, 60% of the cars were in the parking lot on Friday.

(B)

Now, since 60% of the cars were parked on Friday, the remaining percent will be on Saturday.

Therefore, percentage of cars in parking lot on Saturday = 100% - 60% = 40%. This can be verified with the same formula used in part (A).

[tex]=\frac{\textrm{Cars in parking lot on Saturday}}{\textrm{Total cars parked}}\times 100\\\\=\frac{80}{200}\times 100\\\\=\frac{80}{2}=40\%[/tex]

i took the test

Answer: j = 8

Step-by-step explanation: To solve for j in this equation, we want to get j by itself on the left side of the equation. Since j is being multiplied by 5, to get j by itself, we need to divide by 5 on the left side of the equation. Since we divided by 5 on the left side, we must also divide by 5 on the right side.

On the left side, notice that the 5's cancel out so we are simply left with j. On the right side, we have 40 divided by 5 which gives us 8 so we have j = 8.

Finally, remember to check your answer by substituting an 8 back into the original equation. So we have 5 (8) = 40 which is a true statement so our answer checks. Remember to show all your work when solving equations.

Answer:

The each coffee shops receives 4 cases of juice everyday.

Step-by-step explanation:

The juice company produced 8064 cartons of juice in 21 days each day they produced the same number of cartons.

Therefore, each day the company produces [tex]\frac{8064}{21} = 384[/tex] cartons.

The juice company delivers those cartons in 16 areas of coffee shops.

So, each coffee shop receives [tex]\frac{384}{16} = 24[/tex] cartons of juice.

Now, the cartons were delivered in cases of six cartons per case and each coffee shop received an equal number of cases in each delivery.

Hence, each coffee shops receives [tex]\frac{24}{6} = 4[/tex] cases of juice everyday. (Answer)

There are 20 number of DVD's in Louis collection

Solution:

Let "J" be the number of DVD's with Jake

Let "B" be the number of DVD's with Bo

Let "L" be the number of DVD's with Louis

Given that Jake owns twice as many DVDs as Louis

So we can say,

number of DVD's with Jake = 2(number of DVD's with Loius)

J = 2L  ------ eqn 1

Given that Bo has sixty fewer DVDs than five times Louis’s collection

So we can say,

number of DVD's with Bo = 5 times number of DVD's with Louis - 60

B = 5L - 60 ---- eqn 2

Given that Jake and Bo have the same amount of DVDs

number of DVD's with Jake = number of DVD's with Bo

J = B ---- eqn 3

Let us solve eqn 1, 2, 3 to find value of "L"

From eqn 1 and eqn 3,

2L = B  ----- eqn 4

Substitute eqn 4 in eqn 2

2L = 5L - 60

2L - 5L = -60

-3L = -60

Thus there are 20 number of DVD's in Louis collection

Louis has 30 DVDs in his collection.

Let's denote the number of DVDs Louis has as L. According to the problem, Jake owns twice as many DVDs as Louis, so Jake has 2L DVDs. Bo has sixty fewer DVDs than five times Louis's collection, which means Bo has 5L - 60 DVDs.

Since Jake and Bo have the same amount of DVDs, we can set their quantities equal to each other:

2L = 5L - 60

Now, let's solve for L:

5L - 2L = 60

3L = 60

L = 60 / 3

L = 20

Louis has 20 DVDs in his collection.

Number of students in senior class is 130

Solution:

Given that Every student in the senior class is taking history or science

85 of them taking both history and science

106 seniors takes history

109 seniors takes science

To find: number of students in senior class

Let A be the set of the students of the senior class that take history

Let B be the set of students of senior class that they science

The number of students in senior class is given by:

[tex]|A \cup B|=|A|+|B|-|A \cap B|[/tex]

Where,

A = 106 and B = 109 and |A n B| = 85

[tex]|A \cup B|=106+109-85=130[/tex]

Thus number of students in senior class is 130

Answer:

130

Step-by-step explanation:

Since 106 seniors are taking history and 109 seniors are taking science. If we add those numbers of seniors up we get 215, then we subtract the number of seniors that are taking both history and science because we counted them twice. So the total is 215 - 85 = 130. Therefore there are 130 students in the senior class.

Answer:

Step-by-step explanation:

line G :

5y = -2x - 20...put in slope intercept form (y = mx + b)

y = -2/5x - 4....the slope(m) = -2/5

Part A.) slope intercept form for line R...since R is parallel to G, it will have the same slope....so slope(m) = -2/5

(-10,8)...x = -10 and y = 8

slope(m) = -2/5

y = mx + b

8 = -2/5(-10) + b

8 = 4 + b

8 - 4 = b

4 = b

so ur equation is : y = -2/5x + 4 <=== part A answer

since line E is perpendicular to line G, it will have a negative reciprocal slope...all that means is flip the slope and change the sign....so the slope of line E is : (flip -2/5.....-5/2.....change the sign......5/2)

(-10,8)...x = -10 and y = 8

slope(m) = 5/2

y = mx + b

8 = 5/2(-10) + b

8 = -25 + b

8 + 25 = b

33 = b

so ur equation is : y = 5/2x + 33 <== part B answer

The equation for line R is y = -2/5x + 12. The equation for line E is y = 5/2x + 33.

Part A: To write the equation for line R in slope-intercept form, we need to find the slope and the y-intercept. Since line R is parallel to line G, it will have the same slope. The slope of line G can be determined by dividing the coefficient of x by the coefficient of y: -2/5. We can use the point-slope form, y - y1 = m(x - x1), to find the equation. Substituting the coordinates of the point (-10,8), the equation for line R is y - 8 = (-2/5)(x + 10). Simplifying, we get the equation for line R: y = -2/5x + 12.

Part B: To write the equation for line E in slope-intercept form, we need to find the slope and the y-intercept. Since line E is perpendicular to line G, its slope will be the negative reciprocal of the slope of line G. The slope of line G is -2/5, so the slope of line E will be 5/2. Using the point-slope form and substituting the coordinates of the point (-10,8), the equation for line E is y - 8 = (5/2)(x + 10). Simplifying, we get the equation for line E: y = 5/2x + 33.

Answer: The function is EVEN.

Step-by-step explanation:

For this exercise it is important to remember that:

1. A function f(x) is even if and only if:

[tex]f(-x) = f(x)[/tex] for all "x"

2. A function f(x) is odd if and only if:

Answer: 10 and 23

Step-by-step explanation:

Let the first number be x and the second number be y.

Also , let x be the bigger number and y the smaller number.

From the first statement;

x + y = 33 ............................. equation 1

From the second statement

twice the smaller number = 2y

so, if the bigger number is 3 more than two times the smaller number, this means that

x = 2y + 3 .................................... equation 2

Solving the resulting linear equations by substitution method .

substitute x = 2y + 3 into equation 1 , that is

x + y = 33 becomes :

2y + 3 + y = 33

3y + 3 = 33

3y = 30  

y = 10

Substitute y = 10 into equation 2 , that is

x = 2y + 3 becomes

x = 2(10) + 3

x = 20 + 3

x = 23

Find the measure of angle AOC

The triangle AOC is an isosceles triangle, because OA=OC=radius

so

[tex]m\angle OAC=m\angle OCA=28^o[/tex]

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

[tex]m\angle OAC+m\angle OCA+m\angle AOC=180^o[/tex]

substitute the given values

[tex]28^o+28^o+m\angle AOC=180^o[/tex]

[tex]56^o+m\angle AOC=180^o[/tex]

[tex]m\angle AOC=180^o-56^o[/tex]

[tex]m\angle AOC=124^o[/tex]

step 2

Find the measure of arc AC

we know that

[tex]arc\ AC=m\angle AOC[/tex] ----> by central angle

we have

[tex]m\angle AOC=124^o[/tex]

therefore

[tex]arc\ AC=124^o[/tex]

step 3

we know that

The inscribed angle is half that of the arc comprising

[tex]m\angle ABC=\frac{1}{2}[arc\ AC][/tex]

[tex]m\angle ADC=\frac{1}{2}[arc\ AC][/tex]

so

[tex]m\angle ABC=m\angle ADC[/tex]

therefore

[tex]m\angle ABC+m\angle ADC=2m\angle ABC=arc\ AC[/tex]

substitute the value of the arc AC

[tex]m\angle ABC+m\angle ADC=124^o[/tex]
