Answer:
2) 1 dozen apple ( 12 apples ) = $4.92
1 apple = $4.92/12
= $0.41
3) distance = speed × time
= 9/10 × 10
= 9 miles
4) 61 minutes = 183 pages
1 minute = 3 pages
5) 8 days = 7 boats
1 day = 7/8 boats
6) speed = distance/ time
= 288/4
= 72 miles/hour
7) 5 cup of flour = 4 cups of sugar
1 cup of flour = 4/5 cup of sugar
Answer:
1. 50:1
50 ounces of gas per 1 ounce of oil has a 50:1 gas-to-oil ratio
——————————
2. $0.41
Divide $4.92 by a dozen (12) to get the amount per apple
4.92 / 12 = 0.41
——————————
3. 9
9/10 of a mile per minute means the car will travel 9 miles in 10 minutes. This is represented by a ratio of 9:10 or 9/10.
——————————
4. 3
Divide 183 by 61 to get the number of pages per minute
183 / 61 = 3
——————————
5. 7/8
7 boats per 8 days means that 7/8 of a boat can be made in a day. This is represented by a ratio of 7:8 or 7/8.
——————————
6. 72
Divide 288 by 4 to get the number of miles per hour.
288 / 4 = 72
——————————
7. 4/5
4 cups of sugar for every 5 cups of flour means that 4/5 cups of sugar is for every cup of flour. This is represented by the ratio 4:5 or 4/5

Points O, A, B lie on a line. OA = 12 cm and OB = 9 cm. Find the distance between the midpoints of segments
OA
and
OB
in each case.
a
Point O lies on segment
AB
.
Answers
Answer:
10.5
Step-by-step explanation:
Let E be the midpoint of OA and F be the midpoint of OB.
If point O is placed between A and B, then points E and F are placed on different sides from O. The segment OE has length 12÷2=6 cm and segment OF has length 9÷2=4.5 cm. Than EF=6+4.5=10.5 cm.
If point O is placed outside the segment AB, then point B is closer to point O than point A, because OA>OB. Since OE=6 cm and OF=4.5 cm, EF=6-4.5=1.5 cm.
If the order of points is A, O, B, then the midpoints of AO and OB will be separated by half the length of AB: (12 cm + 9 cm)/2 = 10.5 cm.

What is the value of the expression shown below 10+(2x3)^2 divided by 4x (1/2)^3
Answers
Answer:
10 + (2 x 3)^2 / 4 x (1/2) ^3
First do the parentheses
2 x 3 = 6
1 / 2 = 0.5
We are left with
10 + 6^2 /4 x 0.5^3
Do exponents
6 x 6 = 36
0.5 x 0.5 x 0.5 = 0.125
10 + 36 / 4 x 0.125
Divide by 4 and multiply by 0.125
36 / 4 = 9
9 x 0.125 = 1.125
We are left with
10 + 1.125 = 11.125
The answer is 11.125

Which of the following equations describe the line shown below? Check all that apply!
Answers
Answer:
C and E
Step-by-step explanation:
Use the slope formula to first find the slope of the line.
The slope formula is y₂₋y₁ / x₂₋x₁ where (x₁ , y₁) is a point on the graph and (x₂ , y₂) is the other point on the graph. Substituting the values into the slope formula will give you 2 as the slope.
Now use the point-slope formula to find the correct answers.
Point-slope form is y₋y₁ = m(x₋x₁) where y₁ and x₁ are a point on the graph and m is the slope. Substitute both points into the formula (separately) to get C and E as your answers.

Which statement is true about the effects of the transformations on the graph of function f to obtain the graph of function g. g(x) = f(x − 3) + 4
Answers
Answer:
The correct option is D
D) The graph of function f(x) is shifted right 3 units and up 4 units
Step-by-step explanation:
Lets the function be y = f(x)
To shift the graph 3 units to the right, we add -3 to the x term of the function:
Function becomes y' = f(x-3)
Then to shift the graph up by 4 units, we add -4 to the y term of the function:
Function becomes:
y - 4 = f(x-3)
y = f(x-3) +4
g(x) = f(x-3) +4
Hence the correct option is D, as the graph is shifted to the right by 3 units and also shifted up by 4 units
Answer: The correct answer is D. The graph of function f is shifted RIGHT 3 units and up 4

Which best describes the range of the function f(x) = { 0)* after it has been reflected over the x-axis?
all real numbers
all real numbers less than 0
all real numbers greater than 0
all real numbers less than or equal to 0
Answers
Answer:
all real numbers less than 0
Step-by-step explanation:
In the picture attached, the question is shown.
The function described is an exponential decay with the form:
y = ab^x
where a = 2 and b = 1/4
The range of an exponential decay function is all real numbers greater than 0. This means that after f(x) has been reflected over the x-axis its range is all real numbers less than 0.
Jackie goes to the mall every weekend with her friends. Last week, the group spent $28.00 on 2 salads and 4 fruit smoothies. This week, the group spent $38.00 on 3 salads and 5 fruit smoothies. Let x represent the cost of a salad and let y represent the cost of a smoothie. 2x + 4y = 28 3x + 5y = 38 If you multiply the first equation by –3, what could you multiply the second equation by to eliminate the x-variable when adding the equations? What is the cost of a salad? What is the cost of a smoothie?
Answers
Answer:
Salad(x)=6, smoothie(y)=4
Step-by-step explanation:
Salad=x
Smoothie=y
2x+4y=28 (1)
3x+5y=38 (2)
To eliminate the x- variable ,equ(1) is multiplied by -3 and equ(2) is multiplied by 2
-6x-12y=-84 (3)
6x+10y=76 (4)
Add equ (3) and (4)
-2y=-8
y=-8/-2
y=4
Substitute y=4 into equ(1)
2x+4y=28
2x+4(4)=28
2x+16=28
2x=28-16
2x=12
x=12/2

Answers
Answer:
Part A;
There are many system of inequalities that can be created such that only contain points D and E in the overlapping shaded regions.
Any system of inequalities which is satisfied by (-4, 2) and (-1, 5) but is not satisfied by (1, 3), (3, 1), (3, -3) and (-3, -3) can serve.
An example of such system of equation is
x < 0
y > 0
The system of equation above represent all the points in the second quadrant of the coordinate system.
The area above the x-axis and to the left of the y-axis is shaded.Part B:
Part B
It can be verified that points D and E are solutions to the system of inequalities above by substituting the coordinates of points D and E into the system of equations and see whether they are true.
Substituting D(-4, 2) into the system we have:
-4 < 0
2 > 0
As can be seen the two inequalities above are true, hence point D is a solution to the set of inequalities.
Also, substituting E(-1, 5) into the system we have:
-1 < 0
5 > 0
As can be seen the two inequalities above are true, hence point E is a solution to the set of inequalities.

Given that chicken can only be raised in the area defined by y > 3x - 4.
To identify the farms in which chicken can be raised, we substitute the coordinates of the points A to F into the inequality defining chicken's area.
For point A(1, 3): 3 > 3(1) - 4 ⇒ 3 > 3 - 4 ⇒ 3 > -1 which is true
For point B(3, 1): 1 > 3(3) - 4 ⇒ 1 > 9 - 4 ⇒ 1 > 5 which is false
For point C(3, -3): -3 > 3(3) - 4 ⇒ -3 > 9 - 4 ⇒ -3 > 5 which is false
For point D(-4, 2): 2 > 3(-4) - 4; 2 > -12 - 4 ⇒ 2 > -16 which is true
For point E(-1, 5): 5 > 3(-1) - 4 ⇒ 5 > -3 - 4 ⇒ 5 > -7 which is true
For point F(-3, -3): -3 > 3(-3) - 4 ⇒ -3 > -9 - 4 ⇒ -3 > -13 which is true
Therefore, the farms in which chicken can be raised are the farms at point A, D, E and F.
