When did she start charging her phone?

While she was using her phone, at what rate was Lin’s phone battery dying?

Answer:

-12x+3 greater than or equal to 5

-12x greater than or equal to to 2

To turn the negative sign of -12x into positive, we multiply both sides by minus, which shifts the inequality sign.

So, 12x less than or equal to 2

x is less than or equal to 1/6

Therefore, 0, -1, -3, -4 and -6 satisfy this inequality

By performing a change of units, we will see that she did make 1.375 cups of salad dressing.

First, we know that she combines 8 oz of oil and 3 oz of vinegar, then the total volume in ounces is:

V = 8oz + 3 oz = 11 oz

Now we want to know how many cups there are in 11 ounces, so we need to perform a change of units.

We know that:

1 oz = 0.125 cups

Then we can write:

11 oz = 11*(1 oz) = 11*(0.125 cups) = 1.375 cups

Answer:

8 (hopefully)

Step-by-step explanation:

Exponents and Fractions always get dealt with before Math Symbols and Parentheses.

But other than that, you ALWAYS do times or divide from left to right, than plus or minus left to right (unless there's a parentheses, go for the number in the parentheses).

2 by the power of 3 (or 2^3) splits into three twos.

2 * 2 = 4 * 2 = 8 (2^3 = 8)

7 * 8 = 56

56 divided by 4 = 14

8 + 14 = 22

Long story sort

2^3 + 7 * 8 */. 4

8 + 7 * 8 */. 4

8 + 56 */. 4

8 + 14

22

Now than I do not remember what you're supposed to with the "= [Number]" but I do believe you're supposed to sum the left and the right. So I do believe it's 8, now than remember this is not an exact answer, due to not knowing what it's properly to be.

Answer:

  (2³ +7)·8÷4 = 30

Step-by-step explanation:

You want to add parentheses to make a true statement from ...

  2³ +7·8÷4 = 30

We recognize that 2³ +7 = 15 and 8÷4 = 2, and the product of these is 30. So, we need to insert parentheses to make (2³ +7) be evaluated before multiplying by 8 and dividing by 4:

  (2³ +7) · 8 ÷ 4 = 30

Answer:

390 cubic centimeters

Step-by-step explanation:

the volume of a box is the length width and height all multiplied together

so this is what the equation would look like

5(6)(13)

you can split this up into

5(6) * 13

so 5(6) is 30

30(13)

this is 390

so the box is 390 cubic centimeters

Answer:

80

Step-by-step explanation:

When we first look at this, it generally says "90% of what number is 72?" so that's what we can do.

We can change 90% into a decimal, and put in x, which is what our answer will be!

[tex]0.9*x=72[/tex]

We can multiply both sides of this equation by 100, and then divide by 90. After all of this, we have

Answer:

So you can make an equation.

So lets make the unknown number “x”

So it’s twice a number and it’s decreased by 3.
So 2x-3

The result is 25
2x-3=25
Now just solve for the number or “x”

You can solve for x

Step-by-step explanation:

The slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.

The given coordinate points are (-7, -2) and (-15, -14).

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

The slope of the line is

Put (x1, y1) =(-7, -2) and (x2, y2)=(-15, -14)

Slope = m= (-14-(-2))/(-15-(-7))

= -12/(-8)

= 3/2

Therefore, the slope of the line that passes through the points (-7, -2) and (-15, -14) is 3/2.

There are several ways to prove a mathematical statement. These ways include: by contradiction, by induction, contraposition, etc

To prove the statement, we make use of proof by contradiction

From the question:

x is a composite number such that: x > 1

This means that 1 < a < x is a factor of x

This can be represented as:

[tex]x = a * b[/tex]

Where:

Assume that b is less than or equal to a.

Also, let

[tex]b > \sqrt x[/tex]​

This means that:

[tex]\sqrt x < b \ge a[/tex]

The above becomes

[tex]\sqrt x < a[/tex]

Rewrite as:

[tex]a > \sqrt x[/tex]

So, we have:

[tex]x = a * b > \sqrt x * \sqrt x = x[/tex]

The above means that:

[tex]x > x[/tex]

The above inequality is a contradiction because, a number x cannot be greater than itself

This means that, the supposition is wrong.

Hence, the given statement has been proved by contradiction

Similar triangles are triangles that have the same shape but differ in size. Similar items include all equilateral triangles and squares with any side length. In other words, if two triangles are identical, their corresponding angles and sides are congruent and in equal proportion. The " ~ " sign here denotes the resemblance of triangles.

The three-sided polygon is the triangle. The following is the criteria for triangle similarity:

Corresponding angles of both triangles are equal, and corresponding sides of both triangles are proportional to each other.

In Triangle QRS and TUV the similarity sign is used.

Simple interest is a way to figure out how much interest will be charged on a sum of money at a specific rate and for a specific amount of time.

Contrary to compound interest, where we add the interest of one year's principal to the next year's principal to calculate interest, the principal amount in simple interest remains constant.

Given that Krisi took out a $500 discounted loan calculated using a simple interest rate of 5% for a period of 2 years.
