Emily has a road map with a key that shows an Inch on the map equals 5 miles of actual distance. she will drive on two roads to get to the beach. One road is 7 inches long on the map. The other road is 5 inches long. What is the actual distance Emily will drive to the beach? Write the rule you used to find the actual distance.

Answers

Answer 1

Answer:

Emily travelled 35 miles and 25 miles in actual distance.

What is scale in maps?

Scale is defined as the ratio of the length of any object on a model (blueprint) to the actual length of the same object in the real world.

Given that a map is showing a scale of 1 in = 5 miles, we need to find the actual distance if Emily travel 7 inches and 5 inches according to the map,

So,

Since 1 in = 5 mi

Therefore,

7 in = 5 × 7 = 35 miles

Similarly,

5 in = 5 × 5 = 25 miles

Hence Emily travelled 35 miles and 25 miles in actual distance.

Hey. So its pretty easy once u learn the method. All u have to do is count how many zeros there are, and then move the decimal that many times.

18.72---->>>>1872 so the new answer is 1872

hope that helps :)

Find the geometric mean of the numbers. If necessary, give the awnser in simplest form. 2/3 and 1/2.The geometric mean is ____

Answers

Answer:

Geometric mean = 1/√3 or 0.58

Step-by-step explanation:

We have to find the geometric mean of the 2/3 and 1/2.

To find the geometric mean of n terms we use the formula

Geometric mean = $\sqrt[n]{a_(1)* a_(2)* a_(3)....a_(n)}$

By putting the values in the formula

Geometric mean $=\sqrt{(2)/(3)* (1)/(2)}$

$\sqrt{(2)/(6)}=(1)/(√(3) )$

geometric mean = 0.58

Answer:

0.577

Step-by-step explanation:

We are given the following two numbers and we are to find their geometric mean:

$\frac {2} {3}$ and $\frac {1} {2}$

We know the formula for finding the geometric mean:

Geometric mean = $\sqrt[n]{a_1.a_2.a_3...a_n}$

So putting in the given values in the above formula to get:

Geometric mean= $\sqrt [2] {\frac {2} {3} .\frac {1} {2} }$ = $\sqrt {\frac {1} {3} }$

Geometric mean = 0.577

Kate made 4 dresses with 7 yards of fabric. how many yards did she use on 1 dress

Answers

This is a fraction equal to
7 yards ÷ 4 dresses

We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4.

7÷4= 1.75
_
4÷4=1.
Therefore, Kate used 1.75 yards per one dress (1.75 yds. p/ d)

Hope I helped! :)

What is the value of x?
A.2
B.3
C.6
D.7

Answers

Answer:

Step-by-step explanation:

Given 2 secants from a point outside the circle.

Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is

(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)

(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides

x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides

4x + 12 = 20 ( subtract 12 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2 → A
