$15 per hour is the basic rate at a factory. After a 48-hour basic work week, overtime is paid time and a half.
(a) If no one worked overtime and the factory paid $15 840 in wages one week, how many workers are in the factory?
(b) During another week, a worker in the factory earns $810 in wages for himself. How many hours did he work for?
Answer:
(a) There are 22 workers are available in the factory.
Step-by-step explanation:
(a) Let the number of workers in the factory be x.
Basic rate = $15
Working hours in a week = 48 hours
Total wages in a week = $ 15840
If no overtime is to be paid then according to question,
Amount paid to 1 worker = 48 X 15 = $ 720
Amount paid to x worker = 720x
15840 = 720
x = 15840/720
x = 22
June, Gavyn and Alex share some sweets in the ratio 3:5:4. June gets 39 sweets. How many sweets are there altogether?
Answer:
156
Step-by-step explanation:
This is a question in proportion and ratio
Since the ratio in which the sweets are shared is 3: 4 : 5 we can say that the proportion of total sweets that June gets is 3/(3 + 4 + 5) = 3/12 = 1/4
Let the total number of sweets be S
Then 1/4th of this will be June's share and we are given that the actual number June gets is 30
So we have 1/4 x S = 39
Multiplying both sides by 4:
4 x 1/4 x S = 39 x 4
S = 156
So there were 156 sweets altogether
If a rotation takes triangle CAT to C’A’T where is AT
Answer:
The measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.
Step-by-step explanation:
What is a rotation transformation?
A rotation is a transformation that turns the figure in either a clockwise or counterclockwise direction on the coordinate plane. In both transformations the size and shape of the figure stays exactly the same.
For the given situation,
The graph shows the triangle CAT.
If a rotation takes triangle CAT to C'A'T',
then from the definition of rotation transformation the size and shape of the figure stays exactly the same.
Thus the measure of C'T' is same as CT.
Hence we can conclude that the measure of C'T' after rotation of transformation is option (B) square root of 17 is the correct answer.

Alex has 56 books.
Let the number of books Santiago has be x. So, after the donation, the number of books with Santiago is (x - 84). Let the number of books with Alex be y.
Before the donation -
x = 2y : equation 1
After the donation -
y = 2(x - 84) : equation 2
Keep the value of x from equation 1 in equation 2
y = 2(2y - 84)

The graph of the linear equation y = 20 + 10x for the given scenario is attached below.
The Cartesian coordinates of a specific point on the Euclidean plane can be thought of as each solution inside the scenario involving two variables.
A linear equation's solutions define a line inside the Euclidean plane, and each line may be viewed as the aggregate of all solutions to a linear model with two variables. This is how this category of equations came to be known as "linear." The solutions to a system of equations with integer variables collectively constitute a hyperplane in the Euclidean space with size n. (a subdomain of dimension n₁).Because linear equations may frequently accurately represent non-linear systems, they are used extensively in all branches of mathematics as well as in physics and engineering.Here the equation is given as y = 20 + 10x
Therefore at x = 0 , y = 20 and at y = 0, x = -2
This represents that the fixed monthly fee is 20 and the daily fee is 10.

Algebra - The total cost of the fruit 8.26
What is Algebra ?
One of the many branches of mathematics is algebra. Algebra, which is a common thread throughout practically all of mathematics, is broadly defined as the study of mathematical symbols and the rules for manipulating these symbols in formulas.
Given that,
The cost of all fruit is = 1.75/pound
William bought Peaches = 2(2/5)pounds = 12/5pounds
William bought Apricot = 2(1/3)pounds = 7/3pounds
The cost of Peaches = 12/5 x 1.75
= 12 x 0.35
= 4.2
The cost of Apricot = 7/3 x 1.75
= 7 x 0.58
= 4.06
Total cost of the fruit = 4.2 +4.06

A rectangle has perimeter 40cm and was a width. What is an expression of the length in terms of w? What is an expression of the area in terms of w? What is the greatest area that the rectangle could have?
The expression of the length in terms of w is l = 20 - w cm
The expression of the area in terms of w is 20w - w² cm²
The greatest area that the rectangle could have is 400cm²
How to determine the values of the perimeter, length and areaIt is crucial to note that the calculating the perimeter of a rectangles is expressed as;
Perimeter = 2( l +w )
Where;
l is the length of the rectanglew is the width of the rectangleFrom the information given, the perimeter of the rectangle is 40cm
Now, substitute the value for perimeter
40 = 2( l +w )
Divide both sides by the coefficient, we have;
40/2 = 2(l + w)/2
Find the quotient
l + w = 20
Make 'l' the subject of formula
l = 20 - w cm
The formula for determining the area of a rectangle is expressed as;
Area = lw
Now, substitute the value of l as 20 -w in the formula, we have;
Area = 20- w(w)
expand the bracket
Area = 20w - w² cm²
For the greatest area;
Length = perimeter/4 = 40/ 4 = 20 cm
Width =perimeter/4 = 40/ 4 = 20cm
Area = 20(20)
Area = 400cm²
Thus, the expression of the length is l = 20 - w cm
