Dale bought a map of his city it uses a scale of 1 inch = 8 miles Dale house and school are 1 1/2 inches apart on the map how fa
shtirl [24]
Alright, if the original scale was 1 inch = 8 miles, and Dale's house to his school are 1 1/2 inches apart, let's find the amount of miles.

Here's a fast way. 1 inch is 8 miles, and half of 8 equals 4 miles, which is 1/2 of an inch., 8 + 4 = 12 miles. 

So if his house and the school were 12 miles apart, and we we're using the 1 inch. = 6 miles scale, then it'd be 2 inches on the map. 

How?

If 1 inch. = 6 miles
x inches = 12 miles

12/6 = 2 

2 inches = x

A triangle has sides with lengths of 26 meters, 39 meters, and 43 meters. Is it a right triangle?
Ivanshal [37]

Answer: No

Step-by-step explanation:

This triangle is not a right triangle because:

A right triangle must have one side that is exactly 90°.

A triangle with sides 26, 39, and 43 do not have any sides that total 90.

The answer to your question is no.

Best of Luck!

1. (5 pts). A coin is flipped 4 times.
Greeley [361]

Answer:

4/8 or 1/2

Step-by-step explanation:

there are 2 sides of the coin and we flipped it 4 times so 2 x 4 = 8

there are 8 possible outcomes

only 1 side of the coin is face up and we flipped it 4 times so 1 x 4 = 4

so there is a 4/8 (or 1/2 if you want to simplify) chance of flipping a coin four times and landing face up each time.

The set of ordered pairs shown below defines a relation. (MAFS.912.F-IF.2.4){(0, 0), (1, 5), (2, 8), (3, 9), (4, 8), (5, 5), (6,
Ratling [72]

Using the range concept, it is found that the greatest element in the range of this relation is 9.

  • The range of a data-set is the set that contains all possible outputs.
  • The data-set has the format (x,y), in which the values of y are the outputs.

Hence, the range is: {0, 5, 8, 9}.

  • From the given range, the greatest element is 9.
