Explain what happens when you solve the mathematical sentence 4 – ( -5)

Answer:

The percentage increase in A is 44%. The percentage increase in V is 72.8%.

Step-by-step explanation:

The easiest way to go about solving this problem is to pick your own numbers and plug them into the given equations.

For example, let's say that k = 5 and that r = 10.

[tex]A=kr^{2}[/tex]  ⇒ [tex]A= 5 * 10^{2} =500[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V= 5 * 10^{3}= 5000[/tex]

The question is asking, what is the percentage increase if r is increased by 20%. Our chosen k-value will stay the same but our r-value is going to increase. To find the new value of r, we multiply 10, our current value of r, by 1.2. This gives us a new value for r, which is 12.

[tex]10*1.2=12[/tex]

Now, we are going to plug in our new r-value and our k-value into the given equations. k = 5; new r = 12

[tex]A=kr^{2}[/tex] ⇒ [tex]A=5*12^{2}=720[/tex]

[tex]V=kr^{3}[/tex] ⇒ [tex]V=5*12^{3}=8640[/tex]

Next, we have to calculate the percentage increase in our values of A and V. To do this, we use the following formula:

[tex]Percentage Increase = \frac{final - initial}{initial} * 100[/tex]

Percentage Increase for A

Initial value: 500

Final Value: 720

[tex]Percentage Increase = \frac{720-500}{500} * 100 = 44%[/tex]

Percentage Increase for V

Initial value: 5000

Final Value: 8640

[tex]Percentage Increase= \frac{8640-5000}{5000} *100 = 72.8%[/tex]

The percentage increase for A is 44% and the percentage increase for V is 72.8%.

Answer:

7 days

Step-by-step explanation:

If you are using [tex]\frac{5}{6}[/tex] of a bag of coffee per day, and you have [tex]5 \frac{5}{6}[/tex] bags of coffee, you want to find how many times [tex]\frac{5}{6}[/tex] goes into [tex]5 \frac{5}{6}[/tex].

This can be found using division.

First let's convert  [tex]5 \frac{5}{6}[/tex] into an improper fraction:

[tex]5 \frac{5}{6} = \frac{(6\cdot5) + 5}{6} = \frac{35}{6}[/tex]

Now we set up our division equation:

[tex]\frac{35}{6} \div \frac{5}{6}[/tex]

To divide, we multiply by the reciprocal, so:

[tex]\frac{35}{6} \div \frac{5}{6} = \frac{35}{6} \cdot \frac{6}{5} = \frac{210}{30}[/tex]

Dividing both the numerator and denominator of [tex]\frac{210}{30}[/tex] by 30 gets us [tex]\frac{7}{1}[/tex], which is just 7.

Answer:

7 days or 1 week

Step-by-step explanation:

First, know what the equation is. In this case, it's 5 5/6 divided by 5/6, since you need to divide the amount you have by how much you use every day to find out how many days it will last.

The equation is 5 5/6 ÷ 5/6, but since that is harder to solve, turn the 5 5/6 into an improper fraction: 35/6

Now, just solve 35/6 ÷ 5/6, so this means you have to flip your second number and multiply instead divide when dividing fractions, so the new equation is 35/6 ×6/5

That equals 210/30, and if you take out both the 0s (cancel them out), you get 21/3 and after simplifying that, you get 7/1, which is basically 7.

Roxanne's Cafe's coffee can last them 7 days or 1 week.

Answer:

mai is correct

Step-by-step explanation:

a quadrilateral with four congruent sides is never a regular polygon it is a rhombus. hope this helps!

A regular polygon has four congruent sides and four congruent angles.

I do not agree with any of them, because both arguments are incorrect

For a polygon to be a regular polygon, the following conditions must be met

Some quadrilaterals with four congruent sides are:

Rhombus, Kite, Square, etc.

A rhombus has four congruent sides, but all four angles are not congruent.

This means that Diego's argument is incorrect

All sides and angles of a square are congruent.

Because Mai says such polygons can never be a regular polygon, then Mai's argument is also wrong.

Hence, I do not agree with any of them.

Answer:

No answer is equal to 393,500

Step-by-step explanation:

You can try to solve each question.

0.3935 × 10 -6 = -2.065

39.35 × 10 -4 = 389.5

3.935 × 10 -5 = 34.35

3.935 × 10 +5 = 44.35

None of these equal to 393,500

Answer:

An angle is considered a defined term in geometry because defined terms are terms that have a formal definition and can be defined using other geometrical terms.

Angle: Two rays that share the same endpoint, however, the rays take off in different directions. The area in the middle of the two rays is the angle measure.

Answer:

9.9 quarters or Approximately ≈ 10

Step-by-step explanation:

Let n = number of nickels

d =number of dimes

q = number of quarters

n + d + q = 30 coins....... Equation 1

1 nickel = $0.05

1 dime = $0.10

1 quarter = $0.25

0.05n + 0.10d + 0.25q =$ 3.65.......Equation 2

There are twice as many nickels as there are dimes.

Hence

n = 2d

n + d + q = 30 coins

2d + d + q = 30 coins

3d + q = 30 coins........Equation 3

3d = 30 - q

d= 30 - q/3

0.05n + 0.10d + 0.25q =$ 3.65

Since n = 2d

0.05(2d) + 0.10d + 0.25q = $3.65

0.10d + 0.10d + 0.25q = 3.65.........Equation 4

Substitute 30 - q/3 for d in Equation 4

0.10(30 - q/3) + 0.10(30 - q/3) + 0.25q = 3.65

= 3 - 0.10q/ 3 + 3 - 0.10q/3 + 0.25q

(3 - 0.10q) + (3 - 0.10q) + 3(0.25q)/ 3 = 3.65

Cross multiply

(3 - 0.10q) + (3 - 0.10q) + 3(0.25q) = 3 × 3.65

3- 0.10q+ 3 - 0.10q + 0.75q = 10.95

6 - 0.20q + 0.75q = 10.95

0.50q = 10.95 - 6

0.50q = 4.95

q = 4.95/0.50

q = 9.9 quarters

Therefore, the numbers of quarters is approximately ≈ 10 quarters

Answer: [tex]\left\{x | x \in \mathbb{R}, \ -5 \le x < 16\right\}[/tex]

=======================================================

Explanation:

We have some number x such that x is a real number, so we write that as [tex]x \in \mathbb{R}[/tex] which is saying "x is in the real number set".

The portion [tex]-5 \le x < 16[/tex] is how x is restricted. This means x can be -5 or larger, but also must be smaller than 16.

This is from the interval notation [-5, 16). The square bracket means we include -5 as part of the interval, but we exclude 16 because of the curved parenthesis.

The curly braces surrounding everything indicates that we have a set of values.

-----------------

Side note:

If x is an integer, then we can get this roster set {-5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15} showing all of the integers between -5 and 16, including -5 but excluding 16.

Though chances are your teacher will want you to stick to real numbers rather than just integers.
