ANSWER

\huge\green{\overline{\qquad\qquad\qquad\qquad \: \: \: }}

The required coordinates of point B is (-6.5, 0), therefore option a is correct.

To find the coordinates of point B, we can use the midpoint formula. The midpoint formula states that the midpoint of a line segment with endpoints (x₁, y₁) and (x₂, y₂) is given by:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

In this case, point A is given as (1/2, 6) and the center of the circle is at (-3, 3). Let's denote the coordinates of point B as (x, y). Since the center of the circle is the midpoint of the diameter AB, we can set up the following equation:

Midpoint = ((1/2 + x) / 2, (6 + y) / 2) = (-3, 3)

Now, let's solve for x and y:

1/2 + x = -6

x = -6 - 1/2

x = -6.5

6 + y = 6

y = 6 - 6

y = 0

So, the coordinates of point B are (-6.5, 0).

Therefore, the correct answer is an option: a-(-6.5, 0).

Fractions are written as a ratio of two integers

Given the following parameters

Total distance walked = 1/2 miles

Distance walked so far= 1/8 miles

Determine the miles she needs to go further

D = 1/2 - 1/8

D = 4-1/8

D = 3/8

Find the length of x

Answers

It’s a simple ratio. Set it up like this and cross multiply 5/3=4.5/X

The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to go, how many miles do you have to ?

Answers

Scale : 1 inch = 30 miles

So, the ratio between the distance on the map and the real distance is 1:30

When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.

Call the miles we have to go : x

1:30 = 4.5:x

(1x4.5):(30x4.5) = 4.5 : x

4.5 : 135 = 4.5 : x

So, x = 135 => We have to go 135 miles to get to the place we want to go.

The total value of the pennies and nickels was $14.50. Hala counted the coins and found there were 450 coins in all. How many of each type of coin did she have?

Answers

Answer:

Hala will have 200 Pennies and 250 nickels.

Step-by-step explanation:

Let x be = number of Pennies

Let y be = number of nickels


x + y = 450

-x         -x

——————

y = -x + 450



0.01x + 0.05y  = 14.50


0.01x + 0.05( -x + 450 ) = 14.50


0.01 - 0.05x + 22.5 = 14.50
-0.04x + 22.5 = 14.50
          -22.5      -22.5

———————————-
-0.04x  = -8

———      —

-0.04      -0.04

x = 200


200 + y = 450

-200        -200

y = 250


A prism is dilated by a factor of 1. 5. How many times larger is the volume of the resulting prism than the volume of the original prism? Enter your answer as a decimal in the box.

Answers

The volume of the resulting prism is 3.375 times of original volume.

What is a dilation or scale factor?

The factor by which the dimensions of an object are enlarged is called the scale factor.

Let us take the base area of Prizm = a²

Height of the prism = h

Enlarged area = (scale factor)² * previous area

Enlarged area = 1.5²*a² = 2.25a²

Enlarged height = 1.5h

So, enlarged volume = enlarged area* enlarged height

Enlarged volume= 2.25a²*1.5h = 3.375a²h

Enlarged area/previous area = 3.375a²/a² = 3.375

Therefore, the volume of the resulting prism is 3.375 times of original volume.
