What is the distance between -3/7 and 2/8

NISA [10]

Answer:

$\frac{19}{28}$

Step-by-step explanation:

distance between -3/7 and 2/8

$= \frac{2}{8} - \bigg( - \frac{3}{7} \bigg) \\ \\ = \frac{2}{8} + \frac{3}{7} \\ \\ = \frac{2 \times 7}{8 \times 7} + \frac{3 \times 8}{7 \times 8} \\ \\ = \frac{14}{56} + \frac{24}{56} \\ \\ = \frac{14 + 24}{56} \\ \\ = \frac{38}{56} \\ \\ = \frac{19}{28}$

The tires on Miguel's bicycle have a diameter of 28 inches. How many feet has Miguel traveled when the tires complete 15 revolut

-BARSIC- [3]

Answer:

109.9 feet

Step-by-step explanation:

To find how many feet has Miguel traveled, we need to know the circunference of the tire:

C = pi*d = 3.14 * 28 = 87.92 inches

So, for each revolution of the tire, Miguel will travel 87.92 inches. So, to know the distance he will travel, we can do a rule of three:

1 revolution -> 87.92 inches

15 revolutions -> x inches

1/15 = 87.92/x

x = 87.92 * 15 = 1318.8 inches

As the question asks for the distance in feet, we convert from inch to foot by dividing the value of inches by 12, so:

distance in feet = 1318.8 / 12 = 109.9 feet

Please help! Will give Brainliest! -1/32 16 –4 –16

aniked [119]

Answer:

-1/32

Step-by-step explanation:

To evaluate the expression, substitute x = 2 and y = -4. Then use exponent rules to simplify. Review the rules here:

To evaluate or simplify expressions with exponents, we use exponent rules.

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. When we multiply terms with the same bases, we add exponents.

3. When we divide terms with the same bases, we subtract exponents.

4. When we have a base to the exponent of 0, it is 1.

5. A negative exponent creates a fraction.

6. When we raise an exponent to an exponent, we multiply exponents.

7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.

We will use these rules to simplify.

$\frac{1}{2^{-2}x^{-3}y^5} = \frac{1}{2^{-2}2^{-3}(-4)^5} =\frac{2^22^3}{(-4)^5} = \frac{2^5}{(-4)^5}\\\\ =\frac{2*2*2*2*2}{-4*-4*-4*-4*-4} = -\frac{2}{64}=-\frac{1}{32}$
