This question is incomplete
Complete Question
For there are 48 apples and 60 bananas and 96 oranges each basket must contain the same number of each type of fruit. Find the greatest number of baskets you can have
Answer:
The greatest number of baskets you can have is 12 baskets.
And each baskets would contain:
4 apples, 5 bananas and 8 oranges
Step-by-step explanation:
The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48
The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60
The factors of 96 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
Then the greatest common factor is 12.
Therefore, the greatest number of baskets you can have is 12 baskets.
Each baskets would have
For apples
48 apples
48 apples / 12 baskets = 4 apples per basket
For bananas
60 bananas
60 bananas/12 baskets = 5 bananas per basket
For Oranges
96 Oranges/ 12 baskets = 8 oranges per baskets
The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there
Answer:
350 girls
Step-by-step explanation:
So,
The secret to solving problems with ratios is to find the value of one unit.
5:7 = 12 units total
To find one unit, divide the total number of students by the total number of units.
600/12 = a
Simplify
50/1 = a
50 = a
The value of each unit is 50.
Now, multiply the units by the numbers in the ratio.
50(5) = b
250 = boys
50(7) = x
350 = x
There are 350 girls.

[tex]8y^3-6y\\2y(4y^2-3)[/tex]
Factor 2 out because both 8 and 6 can be divided by 2.
Factor y out because there are same y's in a polynomial.
Answer:
2y (4y^2-3)
Step-by-step explanation:
8y^3 - 6y
Over here, we need to first look for the value they have in common
and u can identify that its "y". Now look for a no. that u can multiply both the no.s inside with. In this case, it two...but usually u need to pick the biggest value u can multiply both the no.s with.
So, now we need to put the common value outside the bracket-
2y (......)
2y * 4y^2 can give u 8y^3, therefore this will be the first value inside the bracket, the next value will be 2y*-3 coz it will give u -6y [Be careful of the signs].
So the ans would end up being-
2y (4y^2-3)

I think it might be 4 but i'm not sure
What is the equation of the line that has a slope of 3 and goes through the point (3, 4).
Use the point-slope formula and then solve for y.
y - y_1 = m(x - x_1)
y_1 = 4
x_1 = 3
m = 3
y - 4 = 3(x - 3)
y - 4 = 3x - 9
y = 3x - 9 + 4
y = 3x - 5

if a jigsaw puzzle is priced 17.00 but cost 17.68 at the register what is sales tax rate
Answer:4%
Step-by-step explanation:
From the question, we are informed that a jigsaw puzzle is priced 17.00 but cost 17.68 at the register. This means that the sales tax is (17.68 - 17.00) = 0.68.
Therefore, the sales tax rate will be calculated as:
= (0.68 / 17.00) × 100
= 4%
The sales tax rate is 4%

Please help due in less than 3 hours!!!!!!!! When Anne biked down the canyon, she averaged 30 miles per hour. At this rate, how long did it take her to bike 1 mile?
Answer:
2 min.
Step-by-step explanation:
1h is 60 min so divide 60 by 30 and you get 2
Answer:
It took Anne 1/30 of an hour to bike 1 mile.
Step-by-step explanation:
Unit Rate - 30 miles/ 1 hour
[tex]\frac{30 miles}{1 hour} = \frac{1 mile}{? hour}[/tex]
Based on the visual above, we need to find the proportion.
30 miles divided 30 equals to 1 mile.
What is 1 hour divided by 30? Remember: whatever is done to the numerator must be done to the denominator!
1 divided by 30 equals 1/30. Since the unit is hour, the answer is 1/30 of an hour.

slope intercept form
through: (2, 4) and (1, -3)
Answer: I attached a graph below, hope it helps.
Step-by-step explanation:
A line can be written in the form y = mx + b where m is the slope and b is the y intercept.
Since the slope is given as 4, the equation will be y = 4x + b
Plugging in the point (2,1) to the equation we get 1 = 4(2) + b or 1 = b + 8
Solving for b gives b = -7 so the equation will be y = 4x - 7
The width of a rectangle is three more than twice the length. The perimeter is 96 inches. Find the length and the width.
Answer:
The length of the rectangle is 15 inches and the width is 33 inches
Step-by-step explanation:
The dimensions for the rectangle are as follows:
L=L and W=2L+3
The equation for perimeter of a rectangle is:
P=2l+2w
To Solve:
1. Plug values into perimeter equation
96=2(L)+2(2L+3)
2. Simplify the equation above.
96=2L+4L+6
3. Combine like terms:
96=6L+6
4. Solve for L by subtracting 6 from both sides:
90=6L
5. Solve for L by dividing both sides by 6:
15=L.
6. Plug 15 into the equation for the width:
2(15)+3=w
30+3=w.
