Sandra manages to save 25% of her daily allowance. After 14 days, she has saved RM28. How much is her daily allowance?
Let her daily allowance be RMy.
0.25y x 14 = 28
0.25y=2
y=8
Therefore, her daily allowance is RM8.
Answer:
[tex]x=8[/tex]
Step-by-step explanation: [tex]25[/tex]%[tex]\times14\times[/tex][tex]x=28[/tex]
Solve the equation
[tex]0.25\times14x=28[/tex]
Multiply the monomials
[tex]3.5x=28[/tex]
Divide both sides of the equation by the coefficient of variable
[tex]x=\frac{28}{3.5}[/tex]
Multiply both the numerator and denominator with the same integer
[tex]x=\frac{280}{35}[/tex]
Cross out the common factor

16.5 is 12% of what number?
Answer:
Let's set up an equation;
12/100 * x = 16.5
where 12/100 is 12%
x is the number of the 12%
that would equal 16.5
So solve for x;
12/100 * x = 16.5
12/100x = 16.5
0.12x = 16.5
/0.12 /0.12
x = 137.5

If the measure of ZB is 40°, what measures can ZA and
C be? Select the three correct answers.
20° and 30°
30° and 110°
55° and 85°
60° and 90°
70° and 70°
Answer: 30° and 110°
55° and 85°
70° and 70°
The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:
= 180° - 40°
= 140°
Therefore,
30° + 110° = 140°
55° + 85° = 140°
70° + 70° = 140°

Estimate the size of a crowd at a political rally that occupies a rectangular space with dimensions of 500 feet by 600 feet (to the nearest whole number). Assume that each person occupies 4. 5 square feet.
The size of a crowd at a political rally which occupies a rectangular space with dimensions of 500 feet by 600 feet is 66667 persons.
What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
[tex]A=a\times b[/tex]
Here, (a)is the length of the rectangle and (b) is the width of the rectangle
The size of a crowd at a political rally that occupies a rectangular space with dimensions of 500 feet by 600 feet has to estimated.
First find out the area of this rectangular space using the above formula.
[tex]A=500\times600\\A=300000\rm\; ft^2[/tex]
As each person occupies 4.5 square feet. Thus, the number of person feet in, 300000 square ft are,
[tex]n=\dfrac{300000}{4.5}\\n\approx66667[/tex]
Thus, the size of a crowd at a political rally which occupies a rectangular space with dimensions of 500 feet by 600 feet is 66667 persons.

Mason claims that he can cut a parallelogram into two right scalene triangle. Which diagram best supports his claim
The solution is Option B.
The two right scalene triangles can be formed from the parallelogram B
What is a Scalene Triangle?A scalene triangle is a type of triangle with three different length sides and three interior angles that add up to 180 degrees. Scalene triangles have no equal of parallel sides , hence there is no line of symmetry. The interior angles of a scalene triangle can be acute , right or obtuse angles.
Given data ,
Let the parallelogram be represented as ABCD
Now , the figure ABCD represents a rectangle
So , the measures of angles ∠ABC = measure of angle ∠DCB = 90°
Let the diagonal of the rectangle be AC
The base of the rectangle = BC
The height of the rectangle = AB
So , the diagonal cuts the rectangle into two triangles each having different lengths and angles
And , the two triangles are ΔABC and ΔADC
Now , the triangles ΔABC and ΔADC are right scalene triangles
Hence , the triangles are scalene triangles

What are polynomial?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
In order to factorize the given polynomial, we need to take the common terms out of the polynomial. Therefore, the polynomial can be written as

Maria has $32. She earns $12 for 1 hour of cleaning. She wants to buy a birthday gift for her friend for $125. Enter the minimum number of hours Maria must tutor to be able to buy the gift
Answer:
8 hours
Step-by-step explanation:
First, you must subtract $32 from $125. You end up with $93.
Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.
96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.
While working on homework last night, Kayla completed 4 homework assignments in 3.2 hours. The same night, Karen completed 6 homework assignments in 5 hours. Who spent the least amount of time on homework per hour?
Answer:
Kayla
Step-by-step explanation:
To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework
Kayla: 3.2 ÷ 4 = 0.8
Karen: 5 ÷ 6 = 0.833
Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

Solve the equation:
10 In(100) – 3 = 117
Answer:
x = e^12/100
Step-by-step explanation:
Solve for x over the real numbers:
10 ln(100 x) - 3 = 117
Add 3 to both sides:
10 ln(100 x) = 120
Divide both sides by 10:
ln(100 x) = 12
Cancel logarithms by taking exp of both sides:
100 x = e^12
Divide both sides by 100:
Answer: x = e^12/100
