Answer:

The coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Step-by-step explanation:

Given

To determine

Using the Mid-point formula between (x₁, y₁) and (x₂, y₂)

[tex]\left(x,\:y\right)=\:\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

Here:

(x, y) is the midpoint between (x₁, y₁) and (x₂, y₂)

substituting (x, y) = (0, 5) and (x₁, y₁) = (-18, -10) in the formula

[tex]\left(0,\:5\right)=\:\left(\frac{x_2+\left(-18\right)}{2},\:\:\frac{y_2+\left(-10\right)}{2}\right)[/tex]

equating

[tex]0=\frac{x_2+\left(-18\right)}{2}[/tex]

[tex]x_2-18=0[/tex]

Add 18 to both sides

[tex]x_2-18+18=0+18[/tex]

[tex]x_2=18[/tex]

also

[tex]5=\frac{y_2+\left(-10\right)}{2}[/tex]

[tex]10=y_2+\left(-10\right)[/tex]

[tex]10=y_2-10[/tex]

[tex]10+10=y_2[/tex]

[tex]10+10=y_2[/tex]

[tex]y_2=20[/tex]

Therefore, the coordinates of the other point are:

(x₂, y₂) = (18, 20)

Hence, option A is correct.

Answer:

(x₂, y₂) = (18, 20)

Answer : 14hours

Step-by-step explanation:

If a camera costs 150 dollars and she already has 25 dollars, she needs 125 dollars more

9x14=126 so she needs to works 14 hours

The number of hours needed to babysit in order to purchase the camera is 14.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount in her account = $25

Amount earned per hour = $9

The expression to find the number of x hours to buy the camera.

25 + 9x = 150

9x = 150 - 25

9x = 125

x = 13.89

x = 14

Thus,

The number of hours needed is 14.

Answer:

Step-by-step explanation:First, divide 2.20 by 5 to find the price of a single stamp.

2.20 ÷ 5 = 0.44

One stamp cost $0.44

Now, you multiply this by 7 to find the cost of seven stamps.

0.44 × 7 = 3.08

In 2012, seven stamps cost $3.08

Answer:

$3.08

Step-by-step explanation:

so 5= 2,20

dividing them will get .44

Answer:

The volume of the cylinder is [tex]300\pi[/tex] cubic feet.

Step-by-step explanation:

From Geometry we remember that volumes of a cone and a cylinder with the same radius ([tex]R[/tex]), measured in feet, and height ([tex]h[/tex]), measured in feet, are defined by the following equations:

Cone

[tex]V_{co} = \frac{1}{3}\pi\cdot R^{2}\cdot h[/tex] (1)

Cylinder

[tex]V_{cy} = \pi\cdot R^{2}\cdot h[/tex] (2)

The ratio of the volume of the cylinder to the volume of the cone is:

[tex]\frac{V_{cy}}{V_{co}} = 3[/tex] (3)

If we know that [tex]V_{co} = 100\pi\,ft^{3}[/tex], then the volume of the cylinder is:

[tex]V_{cy} = 3\cdot V_{co}[/tex]

[tex]V_{cy} = 300\pi\,ft^{3}[/tex]

The volume of the cylinder is [tex]300\pi[/tex] cubic feet.

Explanation:

"Without replacement" means the card selected is not put back, and we do not put a copy of that card into the deck.

We have 5 yellow cards out of 5+9+1 = 15 cards total. The probability of picking yellow is 5/15 = 1/3. Let A = 1/3.

After picking that yellow card, we have 5-1 = 4 yellow left out of 15-1 = 14 total. The probability of picking another yellow card, after the first one is not replaced, is 4/14 which reduces to 2/7. Let B = 2/7.

Multiply the values of A and B

A*B = (1/3)*(2/7) = (1*2)/(3*7) = 2/21

The probability of picking two yellow cards, without replacement, is 2/21

The type of triangle is an obtuse triangle.

A triangle is a 3-sided polygon.Every triangle has three sides and three angles, some of which may be the same. When the angles are thesame, the triangle is called an equilateral triangle.

An obtuse triangle is a type of triangle in which one of it's angles is more than 90°.

An acute triangle is a type of triangle in which none of it's angles is UpTo 90°

Also a right triangle is a type of triangle in which one of the angles is exactly 90°.

Therefore since one of the angles is 110 and it is greater than 90°, the angle is an obtuse triangle.

Answer:

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]

Step-by-step explanation:

The slope-intercept form of line is given by the formula:

[tex]y = mx+b[/tex]

Here m is the slope and b is the y intercept

Given

[tex](x_1,y_1) = (1,2)\\(x_2,y_2) = (8,9)[/tex]

First of all, the slope has to be found

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\m = \frac{9-2}{8-1}\\m = 1[/tex]

Putting m=1 in the equation

[tex]y = x+b[/tex]

Putting the point (1,2) in the equation to find the value of b

[tex]2 = 1+b\\b = 2-1\\b = 1[/tex]

The equation is:

[tex]y = x+1[/tex]

Hence,

The equation of line that passes through (1, 2) and (8,9) in slope-intercept form is: [tex]y = x+1[/tex]
