Which expression has a value of 13?
(20 ÷ 4) − 4 + 3 x 2
(18 ÷ 2) + 6 ÷ 6 + 3
(16 ÷ 4) + 3 x 4 − 1
(10 ÷ 2) − 3 + 4 x 2
The expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3
The PEMDAS rule
In order to calculate the expression, we need to use the PEMDAS rule which states:
P is parenthesisE is exponentM is multiplicationD is DivisionA AdditionS is subtractionFrom the question, we are to get the expression equal to 13.
From the given expression,(18 ÷ 2) + 6 ÷ 6 + 3 is equivalent to 13;
(18 ÷ 2) + 6 ÷ 6 + 3
9 + 6 ÷ 6 + 3
9 + 1 + 3
13
Hence the expression that has a value of 13 is (18 ÷ 2) + 6 ÷ 6 + 3

I'm kinda confused can anyone help. I think it's either 32 or 16.
Answer:
It’s B
Step-by-step explanation:
Because the area is 64 and the base is 4, then you would have to divide 64 by 4 to get 16 which is the height!
Answer:
it would be C. h=32 cm
Step-by-step explanation:
the formula for area of a triangle in A=1/2*b*h
so plug what you know into the formula, you know the area, A, and the base, b, so:
64=1/2*(4)*h
now solve what you can:
64=2h
then divide each side by 2 to get h, or the height, alone:
32=h
so, the height is 32 cm!

Grace earned £27,000 last year.
She worked for 32.5 hours a week for 46 weeks.
Calculate her pay per hour.
Give your answer to 2 decimal places.
Answer:
£18.06
Step-by-step explanation:
The computation of her pay per hour is shown below:
= Total earnings last year ÷ Total number of hours she worked
= £27,000 ÷ (32.5 hours × 46 weeks)
= £27,000 ÷ 1,495 hours
= £18.06
Sam works at Handy's Grocery Store. Today, Sam is stocking shelves with bags of sugar.
Each shelf can hold up to 30 kilograms. If each bag of sugar weighs 600 grams, how many
bags can each shelf hold?
Time
elapsed
Answer:
50 bags of sugar
Step-by-step explanation:
There are 1000 grams in 1 kilogram
We know each shelf can hold up to 30 kilograms and we know each bag of sugar weighs 600 grams.
We multiply 30 kilograms (kg) by 1000 to make it equal to grams so:
30 kg x 1000 = 30,000 grams
We should divide 30,000 by 600 to know how many bags each shelf can hold
30,000/600 = 50 bags of sugar

Find the least common denominator for these
two rational expressions.
X3/x2+4x+4 -9/x2+5x+6
Answer:
The least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].
Step-by-step explanation:
Let be the following rational expressions:
[tex]\frac{x^{3}}{x^{2}+4\cdot x + 4}, \frac{-9}{x^{2}+5\cdot x + 6}[/tex]
Then, we factor each denominator:
[tex]\frac{x^{3}}{(x+2)^{2}}, \frac{-9}{(x+3)\cdot (x+2)}[/tex]
Now, we compare each denominator to find all missing binomials so that each expression may have a common denominator:
[tex]\frac{x^{3}}{(x+2)^{2}} \rightarrow (x+3)[/tex]
[tex]\frac{-9}{(x+3)\cdot (x+2)} \rightarrow (x+2)[/tex]
Hence, we conclude that least common denominator of the two rational expressions is [tex](x+2)^{2}\cdot (x+3)[/tex].

Answer:
[tex]\sqrt{125}[/tex]
Step-by-step explanation:
Use Pythagorean theorem since you have a right triangle [tex]15^{2}[/tex] = [tex]10^{2} + x^{2}[/tex]
225 = 100 + [tex]x^{2}[/tex] so x = [tex]\sqrt{125}[/tex]
Answer:
x = 5[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
x² + 10² = 15²
x² + 100 = 225 ( subtract 100 from both sides )
x² = 125 ( take the square root of both sides )
x = [tex]\sqrt{125}[/tex] = [tex]\sqrt{25(5)}[/tex] = 5[tex]\sqrt{5}[/tex] ← in simplest radical form

The interior angle sum of a convex polygon is 2.520 How many sides does the polygon
have?
Complete Question
The interior angle sum of a convex polygon is 2520.How many sides does the polygon have?
Answer:
16 sides
Step-by-step explanation:
The sum of angles in a polygon formula is given as:
(n - 2)180°
Where n = Number of sides of the polygon
Hence:
(n - 2)180°= 2520°
Divide both side by 180°
(n -2) = 2520/180
n - 2 = 14
n = 14 + 2 = 16
Therefore the number of sides the convex polygon has 16 sides.

Simplify: 10x+2x-3= 9
A. x=-1
B. x=-2
C. x=1
D. x=2
Answer:
C. x = 1
Step-by-step explanation:
Combine like terms
10 + 2 − 3 = 9
12 − 3 = 9
Add 3 to both sides of the equation
12 − 3 + 3 = 9 + 3
Add the numbers
12 = 9 + 3
12 = 12
[tex]\frac{12x}{12} = \frac{12}{12}[/tex]
Cancel terms that are in both the numerator and denominator
[tex]x = \frac{12}{12}[/tex]
Divide the numbers
x = 1
Therefore the correct answer is C. x = 1
Answer:
C. x = 1
