Answer:
Increased by 37.5%
Step-by-step explanation:
1. Approach
First, find the amount by which the bill increased. This can be found by subtracting the final amount from the previous amount. Then set up a proportion to find out the percent by which the bill increased. Remember, a proportion is;
[tex]\frac{part}{whole} = \frac{percent}{100}[/tex]
2. Find the increase
Subtract the bill in March from the bill in June;
June - March
110 - 80
= 30
3. Find the percent change
In this case, these are the value which will be used;
[tex]\frac{increase}{March} = \frac{percent}{100}[/tex]
[tex]\frac{30}{80} = \frac{percent}{100}[/tex]
80 percent = 3000
percent = 37.5
1/5 - 1/6
Plz ans. Fasttt
Answer: 1/30
5 and 6 both have a common factor of 30
30 will be our ned denominator
1/5 needs to be multipliued by 6
(since 5 times 6 is 30)
and
1/6 needs top be multiplied by 5
(since 6 times 5 is 30)
then you get 6/30 - 5/30 and that is just 1/30

Johnny and Mark's combined age is 26 years old. Johnny is two years older than twice Mark's age. Write a system of equations and solve for each of their ages
m * 2 + 2 = j
Answer:
Mark is 8
Johnny is 18
Step-by-step explanation:
m * 2 = j - 2
26 - 2 = 24
24 / 3 = 8
8 * 2 + 2 = 18

stamps she has without having to count them. According to a recent
report, a stamp has a mass of approximately 1.32 grams. If the total
weight of Lily's stamp collection is 19.8 grams, about how many
stamps are in Lily's stamp collection?
Answer:
Lily has 15 stamps
Step-by-step explanation:
You would divide 19.8 by 1.32 to get 15.

Answer:
Simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
Step-by-step explanation:
We need to simply the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base.
Solving:
[tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex]
We can write it as:
[tex]\frac{(3\:.\:2)^5}{3^2.2^3}[/tex]
Now using exponent rule: [tex](a\:.\:b)^m=a^m\:.\:b^n[/tex]
[tex]\frac{3^5\:.\:2^5}{3^2.2^3}[/tex]
Now using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex] the bases should be same
[tex]3^{5-2}\:.\:2^{5-3}\\=3^3\:.\:2^2[/tex]
So, simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
Use one or more exponents to write the expression.

Help please I’m almost done
Answer:
33 and -39
Step-by-step explanation:
Angle on a straight line = 180
|5x + 15| = 180 and |5x + 15| = -180
5x + 15 = 180
Subtract 15 from both sides;
5x = 165
Divide both sides by 5;
x = 33
5x + 15 = -180
Subtract 15 from both sides;
5x = -195
Divide both sides by 5;
x = -39

Which graph represents all the real numbers , x, where x <_ -1
Answer:
BStep-by-step explanation:
it's the answerhope this helpsThe graph of the inequality is the second graph.
Which graph represents all the numbers x ≤ -1?The graph will be a number line, such that we have a closed circle at x = -1, and we shade the region to the left (because x must be smaller than -1).
By looking at the possible options, we can see that the number line that meets this condition is the second one, the graph on the upper right corner.
That is the graph of the inequality: x ≤ -1.

Answer:
y = (1/4)x^2 -x -4
Step-by-step explanation:
When you are given a focus and a vertex, the equation of a parabola can be written as ...
y = (1/(4p))(x -h)² +k . . . . . . vertex (h, k); focus-vertex distance p
Here, the vertex is (h, k) = (2, -5) and the focus-vertex distance is 1. That means the equation of the parabola in vertex form* is ...
y = (1/4)(x -2)² -5
Expanding this equation, we get ...
y = (1/4)(x² -4x +4) -5 = (1/4)x² -x +1 -5
Then the standard form equation is ...
y = (1/4)x² -x -4
_____
* In the UK, and perhaps other places, the vertex form is referred to as "standard form." You need to be aware of the form that is being requested here. I have answered using the US version of "standard form." YMMV

"Frank's favorite drink is coke, but the restaurant only has Pepsi." Simple or Compound sentence?
Answer:
Compound sentence
Step-by-step explanation:
A compound sentence is a group of words that consists of at least two independent clauses. The main difference between simple and compound sentences is that a simple sentence is composed of a single clause whereas a compound sentence is composed of two or more clauses. This means that it's a compound since "Frank's favorite drink is coke" is the first independent clause, and "but the restaurant only has Pepsi", is the second independent clause.
