So the ratio of "The scale on a map indicates that 1 inch corresponds to an actual distance of 95 miles.", is...

Scale on map : Actual Distance

1 : 95 miles

We need to find the actual distance for 4.5 inches on the map.

4.5 : x

Just multiply 4.5 with 95 and you would get 427.5 miles.

So the actual distance between the two cities is 427.5 miles.

Hey there!

Since 1 inch is 95 miles, and you need to find 4.5 inches

First multiply 95 * 4 = 380

Now you need to find 0.5 of 95 miles

0.5 * 95 = 47.5

Finally, you add 380 + 47.5 = 427.5

The actual distance between the two cities is 427.5 miles

Hope this helps

PSYCHO15rus [73]
<span>Brittany's mom should get two packages of hot dogs and three packages of buns to get the equal number of hot dogs to buns. In order to determine this, I multiplied 24 by 2 and got 48. I multiplied 16 by 3 and also got 48. The least asmount of packages she should buy are two packages of hot dogs and three packages of buns so she has an equal amount of both.</span>

Determine if the given side lengths could be used to form a unique triangle, many different triangles, or no triangles. explain
ehidna [41]

Given sides of length 300 mm or 190 mm, you can form 4 different triangles:

  1. equilateral with sides 190 mm
  2. equilateral with sides 300 mm
  3. isosceles with two sides 190 mm and one side 300 mm
  4. isosceles with two sides 300 mm and one side 190 mm

The triangle inequality requires the sum of the lengths of any two sides be not less than the length of the third side. Since 2×190 > 300, you can mix and match these side lengths any way you want. With three sides and 2 choices for each, there are only a limited number of possibilities.

In the above, we have not listed ones that are simply rotations or reflections of a congruent triangle. (A 190-190-300 triangle looks the same as a 190-300-190 triangle, for example.)

A bowl has only red, green, and purple grapes. The probability of picking a red grape out of the bowl, eating it, and then picki
Xelga [282]

The probability of picking a green grape is 1/2.

<h3>What is probability?</h3>

Probability is the occurence of likely events. It is the area of mathematics that deals with numerical estimates of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1.

Since the probability of picking a red grape out of the bowl, eating it, and then picking a green grape out of the bowl is 1/8 and probability of picking just a red grape is 1/4 .

The probability of green grape will be the division. This will be:

= P(R and G) / P(R)

= 1/8 ÷ 1/4

= 1/8 × 4/1

= 1/2

The probability is 1/2.

I need help with math homework #2 algebra
OverLord2011 [107]

Answer:

A. (0, -2) and (4, 1)

B. Slope (m) = ¾

C. y - 1 = ¾(x - 4)

D. y = ¾x - 2

E. -¾x + y = -2

Step-by-step explanation:

A. Two points on the line from the graph are: (0, -2) and (4, 1)

B. The slope can be calculated using two points, (0, -2) and (4, 1):

slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 -(-2)}{4 - 0} = \frac{3}{4}

Slope (m) = ¾

C. Equation in point-slope form is represented as y - b = m(x - a). Where,

(a, b) = any point on the graph.

m = slope.

Substitute (a, b) = (4, 1), and m = ¾ into the point-slope equation, y - b = m(x - a).

Thus:

y - 1 = ¾(x - 4)

D. Equation in slope-intercept form, can be written as y = mx + b.

Thus, using the equation in (C), rewrite to get the equation in slope-intercept form.

y - 1 = ¾(x - 4)

4(y - 1) = 3(x - 4)

4y - 4 = 3x - 12

4y = 3x - 12 + 4

4y = 3x - 8

y = ¾x - 8/4

y = ¾x - 2

E. Convert the equation in (D) to standard form:

y = ¾x - 2

-¾x + y = -2
