Ms. Lui earned an annual income of 775,000, what is the weekly salary?
Answer:
$14,903.85
Step-by-step explanation:
So, Ms. Lui earns $775,000 each year. To find the weekly salary, we have to divide the annual income by the amount of weeks in a year. There are about 52 weeks in one year. Let's find the weekly salary:
[tex]\frac{775000}{52} = 14,903.85[/tex]
Therefore, Ms. Lui earns $14,903.85 a week.

Answer:
The number of children is 2500 and the number of adults that attended the game is also 2500.
Step-by-step explanation:
Let us consider that, number of children be x and number of adults be y that attend game.
Since, total 5000 people attend the game.
It costs $3 for children and $7 for adults and the total takings at the door was $25000
Substitute value of x from equation 1 into equation 2.
So that,
Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.
Design an instructional activity that could help learners recognise that decimal
fractions can be applied across environmental situations (relating to activities
in real life).
Fraction refers to a part of a whole; e.g when cup is not completely filled, it covers only a part of the cup
What is fraction?The term fraction refers to a part of a whole. To design an instructional activity that could help learners recognize that decimal fractions can be applied across environmental situations, we could look at certain things in the house.
For instance, when cup is not completely filled, it contains water that covers only an fraction of the cup. Also, we could boil a part and not a whole cup of rice. These are all examples of fractions.

Anne, Bridget, and Sasha shared a sum of money. Anne took 1/3 of the total amount, and Bridget took 1/4 of the remaining money. After both of them had taken their share, Sasha took 1/2 of what was left. If Anne took $160, how much did Sasha take?
Answer:
180
Step-by-step explanation:
160= 1/3 * total
160*3 = total
480 = total
bridget = 1/4(total)
bridget = 1/4(480)
bridget took 120
Sasha took 1/2 of 360
Sasha took $180.
A solution contains 8% salt. How much pure water should be added to 25 ounces of the solution to dilute it to a 3% solution? Round to the nearest hundredth if needed.
41.67 ounce of pure water should be added to 25 ounces of the 8% salt solution to dilute it to a 3% solution
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of pure water needed to dilute the solution. Hence:
8% * 25 = 3% * (x + 25)
2 = 0.03x + 0.75
x = 41.67 ounce

Jasmine played in a basketball tournament. The ratio of the number of baskets she missed during the tournament to the number of baskets she made is 3:8. If Jasmine missed 9 baskets during the tournament, how many baskets did she make? Draw a diagram to demonstrate how you found your answer.
By using the given ratio, we will conclude that she made 24 baskets.
how many baskets did she make?
We know that the ratio of the number of baskets she missed to the number of baskets she made is 3:8.
This means, for each 3 missed baskets, she made 8.
Here we know that she missed 9. If we divide that by 3, we get:
9/3 = 3.
This means that she missed 3 baskets 3 times. And for each one of these 3 times she makes 8 baskets (for the given ratio).
Then we conclude that she makes 8*3 = 24 baskets.

The exact height of the triangle is 20.8ft
The area of the right tringle in radical form is 72√3 ft²
The area of the triangle in decimal form is 124.7 ft²
How to find the side and area of a right angle triangle?The side XY or height of the triangle can be found as follows:
Using trigonometric ratios,
tan 60° = XY / 12
XY = 12 tan 60°
XY = 12 × 1.73205080757
XY = 20.7846096908
height = 20.8ft
The area of XYZ = 1 / 2 bh
where
b = baseh = heightTherefore,
The area of XYZ = 1 / 2 × 12 × 20.8 = 124.707658145 = 124.7 ft²
The area in radical form = 1 / 2 × 12 × 12 tan 60°
The area in radical form = 1 / 2 × 12 × 12 × √3 = 144√3 / 2 = 72√3 ft²

The product of two numbers is 5, if their sum is 9/2. What are the numbers? with detail explaniation
Answer: The numbers are 2 and 2.5
Explanation:
Let one number be "x" and another "y", Note: 9/2 = 4.5 [in decimal form]
[tex]\rule{185}{2}[/tex]
Their product :
[tex]\hookrightarrow \sf x \ \cdot \ y = 5[/tex]
[tex]\hookrightarrow \sf x = \dfrac{5}{y} \quad \ \ \leftarrow \quad equation _1[/tex]
Their sum :
[tex]\hookrightarrow \sf x + y = 4.5[/tex]
[tex]\hookrightarrow \sf x = 4.5-y \quad \ \ \leftarrow \ equation_2[/tex]
Solve them simultaneously:
[tex]\rightarrow \sf 4.5 - y = \dfrac{5}{y}[/tex]
cross multiply
[tex]\rightarrow \sf y(4.5 - y) = 5[/tex]
distribute inside parenthesis
[tex]\rightarrow \sf -y^2 +4.5y - 5 = 0[/tex]
multiply by -1
[tex]\rightarrow \sf y^2 -4.5y + 5 = 0[/tex]
factor them out
[tex]\rightarrow \sf ( y - 2.5)(y - 2)= 0[/tex]
set to 0
[tex]\rightarrow \sf y = 2.5, \ 2[/tex]
Another number:
When one number is 2.5, then another: 4.5 - 2.5 = 2
When one number is 2, then another: 4.5 - 2 = 2.5
Hence, the numbers are 2.5 and 2
Check:
Product: 2 × 2.5 = 5Sum: 2 + 2.5 = 4.5 or 9/2The numbers obtained by the given condition that the product of two numbers is 5 if their sum is 9/2 will be x =( 2 or 5/2) and y = ( 2 or 5/2).
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the first number is x and the second is y then
Product xy = 5
Sum x + y = 9/2
substitute y = 9/2 - x into first
x( 9/2 - x) = 5
2x² - 9x + 10 = 0
2x² -5x -4x + 10 = 0
x( 2x - 5 ) -2( 2x -5 ) = 0
(x -2)(2x -5) = 0
x =2 and x = 5/2
Corresponding to x y will be y = 2 and y = 5/2.

Answer:
140
Step-by-step explanation:
Angles in a triangle add up 180 :
180 = 107 + 33 + y
y = 180 - (107+33)
y = 180 - 140
y = 40
Angles on a straight line add up to 180 so :
180 = x + y
180 = x + 40
x= 180 - 40
x = 140
Hope this helped and have a good day
Answer:
x = 140°

The Exterior Angle Theorem states that the two remote angles in a triangle is equal to the exterior angle.
Application
In this case, the two remotes angles are 107 and 33°, and the exterior angle is x. Now, all we have to do is just add 107 and 33 to get our answer.
