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.

She needs to walk 3/8 of a mile to reach her destination

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

Hence she needs to walk 3/8 of a mile to reach her destination

The total circumference of the circle is: C = 2*pi*radius = 2*(3.14159)*(6) = 37.7 m The total circle has 365o.  Your arc has only 135o.  Hence: 135o           x-------  =  -------------365o          37.7 m where x is the length of the 135o arc.  Solve for x.

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

Answer:

(a) (-∞, -8) (-6, -4) (-2, ∞)

(b) -6, -2

(c) negative

(d) 5

Step-by-step explanation:

(a)  A function is "decreasing" when the y-value decreases as the x-value increases.

⇒ the function is decreasing over these intervals : (-∞, -8) (-6, -4) (-2, ∞)

(b) Local maxima are the points on the function where it reaches a maximum.

⇒ maxima at x = -6 and x = -2

(c) negative

(d) 5

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

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.

ANSWER

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).
