Answer:

1. The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. The distance between the points (-3,8) and (-4, -2) is 10.04

Step-by-step explanation:

1. Which of the following is the correct form of the distance formula?

The formula used to the find distance formula is: [tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

2. Use the distance formula to find the distance between the points (-3.8) and (-4. -?)

Note: Since the y-term in (-4,-) is missing So, I am using -2 to solve the question and find distance. You can use the term given in question and replace it with -2 and use this solution as reference to solve and find the correct answer.

We have points (-3,8) and (-4,-2)

Putting values in distance formula and finding result:

[tex]Distance\:Formula=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

We have x_1=-3, y_1=8, x_2=-4, y_2=-2

[tex]Distance=\sqrt{(-2-(-3))^2+(-2-8)^2}\\Distance=\sqrt{(-2+3)^2+(-2-8)^2}\\Distance=\sqrt{(1)^2+(-10)^2}\\Distance=\sqrt{1+100}\\Distance=\sqrt{101}\\Distance=10.04[/tex]

So, the distance between the points (-3,8) and (-4, -2) is 10.04

The regular costs 11 dollars each while the deluxe cost 23 each.

Step-by-step explanation:

You need to setup two equations.I used two variable for the prices of the types of pizzas because they are unknown.I used x for the cost of regular and y for the cost of deluxe.The equation I did are 10x+y=133 and 7x+9y=284.You need to solve one equation only.I solved the first one.

Answer:

1/5

Step-by-step explanation:

Step-by-step explanation:

Vineisha earned 110 percent on the science quiz which was about the phases of the moon.

Vineisha earned 22 out of 20 points on her science quiz over the phases of the moon

The percent earned can be calculated by dividing 20 by 22 and then multiplying the result by 100

22/20 × 100

= 1.1 × 100= 110

Hence the percent she earned on the quiz is 110%

Answer:

The length of the shorter part of the wire is 24 centimeters.

Step-by-step explanation:

Let [tex]L[/tex] the total length of the piece of wire, where [tex]L-x[/tex] and [tex]x[/tex] are the perimeters of the greater and lesser squares. All lengths are measured in centimeters. Since squares have four sides of equal length, the side lengths for the greater and lesser squares are [tex]\frac{L-x}{4}[/tex] and [tex]\frac{x}{4}[/tex]. From statement we find that the sum of the areas of the two squares ([tex]A[/tex]), measured in square centimeters, is represented by the following expression:

[tex]A = \left(\frac{L-x}{4} \right)^{2}+\left(\frac{x}{4} \right)^{2}[/tex] (1)

And we expand this polynomial below:

[tex]A = \frac{L^{2}-2\cdot L\cdot x +x^{2}}{16} + \frac{x^{2}}{16}[/tex]

[tex]A = \frac{L^{2}-2\cdot L\cdot x +2\cdot x^{2}}{16}[/tex]

[tex]2\cdot x^{2}-2\cdot L\cdot x +L^{2}-16\cdot A = 0[/tex] (2)

If we know that [tex]L = 76\,cm[/tex] and [tex]A = 205\,cm^{2 }[/tex], then the length of the shorter part of the wire is:

[tex]2\cdot x^{2}-152\cdot x +2496 = 0[/tex]

By the Quadratic Formula, we determine the roots associated with the polynomial:

[tex]x_{1} = 52\,cm[/tex], [tex]x_{2} = 24\,cm[/tex]

The length of the shorter part of the wire corresponds to the second root. Hence, the length of the shorter part of the wire is 24 centimeters.

Answer:

21/8

Step-by-step explanation:

okay so what we have to do is called flip n' multiply, so we leave the first fraction the way it is and the second one, we flip. so instead of 3/9, it would be 9/3. now we just do 7/8 times 9/3 to get 63/24 which I believe will be simplified to 21/8

Answer:

Seven eighths divided by three ninths is equal to twenty-one eights.

Step-by-step explanation:

The easiest way to divide one fraction by another is to simply multiply the first one by the second one.  It's that easy:

[tex]\frac{7}{8} \div \frac{3}{9}[/tex]

is exactly the same as:

[tex]\frac{7}{8} \times \frac{9}{3}[/tex]

Which we can then solve by multiplying the numerators by each other and multiplying the denominators by each other

[tex]\frac{7}{8} \times \frac{9}{3}\\\\ = \frac{7 \times 9}{8 \times 3} \\\\ = \frac{63}{24} \\\\ = \frac{21}{8}[/tex]

Another way you can solve it is by noting that in the second number, both the numerator and denominator are divisible by 3, which gives a way to simplify before doing the division:

[tex]\frac{7}{8}\div \frac{3}{9}\\\\= \frac{7}{8}\div \frac{1}{3}\\\\= \frac{7}{8}\times \frac{3}{1}\\\\= \frac{7}{8}\times 3\\\\= \frac{21}{8}[/tex]

Answer: 16π

Step-by-step explanation:

First, solve for total area:

A = π(8^2) = 64π

Then, find 1/4 of the area of the whole (since this is only a quarter circle)

A/4 = (64π)/4 = 16π

Answer:

There are 72 crayons in the box

Step-by-step explanation:

Fractions

To solve this problem we'll manage numbers as fractions to keep the precision up to the end of it.

Lynn has a box of crayons. It's given 4/9 of the crayons are blue. The remaining crayons are:

[tex]1-\frac{4}{9}=\frac{5}{9}[/tex]

From that portion, 65% are red, or equivalently, 35% are yellow.

We write 35% as a fraction:

[tex]\displaystyle 35\%=\frac{35}{100}=\frac{7}{20}[/tex]

Thus, the portion of yellow crayons is:

[tex]\displaystyle \frac{7}{20}\cdot \frac{5}{9}=\frac{7}{36}[/tex]

This fraction of x crayons is equal to 14, thus:

[tex]\displaystyle x=\frac{14}{\frac{7}{36}}=14\cdot\frac{36}{7}[/tex]

x = 72

There are 72 crayons in the box
