Answer:

Slope intercept form:

y = 2x + 8

Step-by-step explanation:

Parallel lines have same slope. SO find the slope of 2x - y = 2

2x - y = 2

    -y = -2x + 2

Multiply both sides by (-1)

-y*(-1) = -2x*(-1) + 2 *(-1)

y = 2x  - 2

Slope = 2

m =2 and point (1 , 10)

Slope point form: y - y1 = m(x -x1)

y - 10 = 2(x - 1)

y - 10 =2x - 2

    y = 2x - 2 + 10

   y = 2x + 8

Answer:

Step-by-step explanation:

To find the diagonal, use Pythagorean theorem,

diagonal² = side² + side²

                = (9√3)² + (9√3)²

                = 9²(√3)² + 9²(√3)²

                = 81*3 + 81*3

                = 243 + 243

                 = 486

diagonal = √486 = 22.05 units

Answer:

The first one

Step-by-step explanation: the ABC triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The first triangle has a 25-degree angle and a 90-degree angle as you can see by the marks. The second one does have a 90-degree angle but it's a different shape and has no 25-degree angle. The third one has both angles 25 and 90 but if you look close it's a different shape. The last one does not have a 90-degree angle but it does have a 25-degree angle and it's a different shape.

So it would be the first option.

Answer:

x = 9.4868

Step-by-step explanation:

For this problem we can use the Pythagorean Theorem

Pythagorean theorem = [tex]a^2+b^2=c^2[/tex]

IN THIS CASE C = X

A and B are the side and base lengths of a right triangle.

C is the Hypotenuse side.

[tex]9^2+3^2=c^2[/tex]

Solve...

81 + 9 = [tex]c^2[/tex]

90 =[tex]c^2[/tex]

[tex]\sqrt{90}[/tex] = c

c = 9.4868

Answer:

Step-by-step explanation:

The area for the sector of a circle is

[tex]A_s=\frac{theta}{360}*\pi r^2[/tex]  where theta is the measure of the central angle. We have some given values to fill in:

Area is 64π and the central angle is 90°, so all we have left to find is the radius. Filling into the equation:

[tex]64\pi =\frac{90}{360}*\pi r^2[/tex]

Let's get that solved for r-squared first:

[tex]\frac{360(64\pi )}{90\pi } =r^2[/tex]

Doing all the math on that gives us:

[tex]256=r^2[/tex]

Take the square root of both sides and get that r = ±16. BUT we know that lengths cannot be negative, so we disregard the -16 and say that the radius is 16 inches.

Answer:

She needs 4 more marbles for the 9th jar.

Step-by-step explanation:

Multiples of 8:

M = {0, 8, 16, 24, 32, 40, 48, 56, ...}

First, she puts in the greatest possible number of marbles into each of the 1st 8 jars.

The total is the greatest multiple of 8 below 50, which is 48.

In each jar:

48/8 = 6

The remaining marbles are then put into the 9th jar.

50 - 48 = 2 in the 9th jar.

How many more marbles does she need for the 9th jar such that every jar has the same number of marbles?​

All others have 6, the 9th has 2.

6 - 2 = 4

She needs 4 more marbles for the 9th jar.

Answer:

H  mean of data for store 1 is greater than mean for store 2

Step-by-step explanation:

mode for store 1 = 3

mode for store 2 = 2

range for store 1 = 6

range for store 2 = 6

mean for store 1 = 3.3125

mean for store 2 = 2.588

median for store 1 = 3

median for store 2 = 2

Answer:

a) m<F = 70

b) AB = 6

Step-by-step explanation:

a)

Since this is an isoceles triangle, the base angles are equal so:

2x + 40 = 180

2x = 140

x = 70

b)

Since all of the angles are equal, this is an equilateral triangle. This also makes all of the sides equal and the same.

Step-by-step explanation:

8 girls are there in Mrs. Sanchez' class.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Based on the given conditions, formulate

2 girls ⇒ 3 boys

X girls ⇒ 12 boys

3X = 12 × 2

⇒ 3X = 24

⇒ X = [tex]\frac{24}{3}[/tex]

⇒ X = 8

Hence, 8 girls are there in Mrs. Sanchez' class.
