Well you can make a proportion to see if the values (2 miles in 1/2 hour and 1 mile in 15 minutes) are equal to each other or not.

**We need to convert 15 minutes into hours --> 15 minutes / 60 minutes = 1/4 hour $\frac{2 \text{ miles}}{ \frac{1}{2} \text{ hours} } = \frac{1 \text{ mile}}{ \frac{1}{4} \text {hour}}$

Cross-multiply...
1/2(1) = 2(1/4) <em>*is this true? </em>
1/2 = 2/4 <em /><em>*if you simplify 2/4 by dividing the numerator and denominator by 2 you get 1/2
</em><em />1/2 = 1/2 <em>**this is correct!</em>

So it is true!

2 miles = 1/2 hour (a whole hour is 60 mins so half of that is 30 mins) 1 mile = 15 mins (15 mins is half of 30 mins) so yes its true

Find the value of x that makes m || n

ch4aika [34]

Answer:

x=133

Step-by-step explanation:

Given: m║n

This means that 147 and x+14 are <em>alternate exterior angles</em>. This also means that they are equivalent. We can use this information to set up an equation:

x+14=147

Subtract 14 from both sides to isolate x

x=133

<h2><u>CIRCUMFERENCE</u></h2>

<h3>Possible Question:</h3>

» The diameter of a circle is 11 in. What is the circle's circumference?

<h3>Answer:</h3>

$\blue{\bold{34.54 \: \:in}}$

— — — — — — — — — —

<h3>Step-by-step explanation:</h3>

To find the circumference, use pi (π), a mathematical constant. Its value is approximately equal to 3.14.

— Multiply the diameter with π in order to get the circumference of a Circle.

$\sf \: given : \underline{ \tt \: d = 11 \: in \: } \\ \\ \tt \: \: C = π × d \tt \\ \tt \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: = 3.14×11 \: in \\ \tt \: \: \: \: \: \: \: \: \: \: \: \: \: \: = \underline{ \boxed{ \purple{ \bold{ 34.54\:in}}}}$

Therefore, the circumference of the circle is 34.54 inches.

Solve the math problem

Nadusha1986 [10]

<u>Answer:</u>

Below!

<u>Explanation:</u>

Exponents are small numbers that defines how many times does the base needs to multiply itself. Two exponents can also be classified in words. 'Squared' defines a number multiplying itself two times. 'Cubed' defines a number multiplying itself three times. If there is a zero as the base's exponent, this means that the result will always be 1. Now, let's solve all the problems together.

2¹ = 2
3⁵ = 3 x 3 x 3 x 3 x 3 = 243
4³ = 4 x 4 x 4 = 64
6⁴ = 6 x 6 x 6 x 6 = 1256
7⁴ = 7 x 7 x 7 x 7 = 2401
1⁶ = 1 x 1 x 1 x 1 x 1 x 1 = 1
8² = 8 x 8 = 64
2³ = 2 x 2 x 2 = 8
4⁴ = 4 x 4 x 4 x 4 = 256
10³ = 10 x 10 x 10 = 1000
12² = 12 x 12 = 144
5⁴ = 5 x 5 x 5 x 5 = 625
6² = 6 x 6 = 36
3⁶ = 3 x 3 x 3 x 3 x 3 x 3 = 729
7³ = 7 x 7 x 7 = 343
2⁴ = 2 x 2 x 2 x 2 = 16
11⁰ = 1
4³ = 4 x 4 x 4 = 64
1¹² = 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 x 1 = 1
