Answer:
15 Hours
Step-by-step explanation:
So you have one block, and your friend has two.
We know that you work for 3 hours, this means that your only block must represent 3 hours.
And all the blocks represent the same amount of time, then each one of the two blocks of your friend also represents 3 hours.
Then in total, he tutored for 3 hours + 3 hours = 6 hours.
Therefore, you still have only one block, but now your friend has 5.
Using the same reasoning as above, we can conclude that each block represents 3 hours, and your friend has 5 of them, this means that he tutored for:
5*3 hours = 15 hours

Joel has just moved to a new town and wants to share plates of baked goods with his
neighbors. He has 20 cookies and 5 brownies to share and wants to split them equally
among the plates with no food left over. What is the greatest number of plates he can make to share
Answer:
Marta can arrange a maximum of 3 plates.
Solution:
Given, Marta has just moved to a new town and wants to share plates of baked goods with her neighbors.
She has 18 cookies and 15 brownies to share, and wants to split them equally among the plates with no food left over.
We have to find what is the greatest number of plates she can make to share?
Now, let the number of brownies per each plate be n.
Then, number of plates used =
Here, n is number of brownies per plate and is number of cookies per plate.
So, both n and should be whole numbers. Then, for to be whole number 6n must be an multiple of 5.
And to be particular, n should be a multiple of 5 as 6 is not multiple of 5.
So, possible n values are, 5, 10, 15. We need not take above 15 as number of brownies available are 15
In order to arrange in more plates we have to take less count in single plate. Then, n = 5.
Now, number of plates
Hence, Marta can arrange a maximum of 3 plates.
Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centimetres. Write down, in imillimetres, the lower bound of his measurement.
The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the measured magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
[tex]y = x + \epsilon[/tex] (1)
Where:
[tex]x[/tex] - Measured magnitude, in millimeters.[tex]y[/tex] - Possible magnitude, in millimeters.[tex]\epsilon[/tex] - Uncertainty, in millimeters.If we know that [tex]y = 67.5\,mm[/tex] and [tex]\epsilon = 1\,mm[/tex], then the lower bound of the measurement is:
[tex]y = 67.5\,mm - 2\cdot (1\,mm)[/tex]
[tex]y = 65.5\,mm[/tex]
The lower bound of the measurement is 65.5 millimeters.

Ahmed bought 5 equally priced markers for $3.25.
How much will 12 of these markers cost?
$1.35
$6.68
$7.80
$8.46
Answer:
$7.80
Step-by-step explanation:
Find the unit price by dividing 3.25 by 5.
3.25 ÷ 5 = 0.65
Now that you have the unit price, multiply it by 12 to find the total price of the 12 markers.
0.65 × 12 = 7.80
Thus, 12 of the same markers that Ahmed bought will cost $7.80.
The cost of 12 markers is given by the equation A = $ 7.80
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the number of markers be n = 5
The cost of 5 markers = $ 3.25
So , the cost of 1 marker = cost of 5 markers / 5
On simplifying the equation , we get
The cost of 1 marker = 3.25 / 5
The cost of 1 marker = $ 0.65
Now , the cost of 12 markers = 12 x cost of 1 marker
Substituting the values in the equation , we get
The cost of 12 markers A = 12 x $ 0.65
The cost of 12 markers A = $ 7.80
Hence , the equation is A = $ 7.80 , where A is the total cost of markers

Plug in -3 for f(x) into the first equation.
-3 = x^2 - 5x + 3
x^2 - 5x + 6 = 0
Factor!
(x - 3)(x - 2) = 0
Set each binomial equal to 0 to get the x-value of the point.
x = 3
x = 2
Plug each x-value back into the first equation (the answer should be -3, though it's always good to check) to get the y-value.
(3)^2 - 5(3) + 3
9 - 15 + 3
-6 + 3
-3

Answer:
Step-by-step explanation:
ZTU = 75, since RTS and ZTU are vertical angles, and RTS = 75.
TZU = 43, since TZU and QZX are vertical angles, and QZX = 43.
ZUT = 180 - ZTU - TZU = 180 - 75 - 43 = 62, since triangle ZUT is shown in the diagram, and the sum of its interior angles = 180.
YUW = 180 - 79 - 62 = 39, since TUW is a straight angle, which measures 180 degrees, and angle TUW is the sum of angle ZUY and angle ZUT and angle YUW, by the diagram.
YVU = 180 - ZUY - YUW = 180 - 68 - 39 = 73, since triangle YUV is shown in the diagram, and the sum of its interior angles = 180.
YVW = 180 - YVU = 180 - 73 = 107, since YVW and YVU are supplementary.
Jessica purchased a DVD that was on sale for 12% off. The sales tax in her county is 3%. Let y represent the original price of the DVD. Write an expression that can be used to determine the final cost of the DVD.
Answer:
is it y=12x+3
Step-by-step explanation:
x=DVD. DVD =12
The expression that represents the final price of the DVD is 0.9064y
How to determine the final cost?The given parameters are:
Discount = 12%Sales tax = 3%Original price = yThe final cost is calculated using:
Final = Original price * (1 - discount) * (1 + sales tax)
So, we have:
Final = y * (1 - 12%) * (1 + 3%)
Evaluate the expression
Final = 0.9064y
Hence, the expression that represents the final price of the DVD is 0.9064y
