Mimi needs eleven 18-inch pieces of rhinestone ribbonShe purchased 5 yards of the ribbon shown at the rightWhat is the total amo

GalinKa [24]

Answer:

5.5 yards.

Step-by-step explanation:

We have been given that Mimi needs eleven 18-inch pieces of rhinestone ribbon. She purchased 5 yards of the ribbon. We are asked to find the total amount of ribbon that Mimi needs.

First of all, we will multiply 11 by 18 to find amount of ribbon needed in inches as:

$\text{Amount of total ribbon in inches}=11\times 18\text{ inches}$

$\text{Amount of total ribbon in inches}=198\text{ inches}$

We know that 1 yard equal to 36 inches. To convert 198 inches into yards, we will divide 198 by 36 as:

$\text{Amount of total ribbon in yards}=198\text{ inches}\times \frac{1\text{ Yard}}{\text{36 inches}}$

$\text{Amount of total ribbon in yards}=\frac{1\text{19 Yard}}{36}$

$\text{Amount of total ribbon in yards}=5.5\text{ Yards}$

Therefore, the total amount of ribbon that Mimi needs is 5.5 yards.

Write the solution as an ordered pair (x,y)

garik1379 [7]

Answer:

(-2, -3)

Step-by-step explanation:

2x + 1 = 3x + 3

minus 3 from both sides

2x - 2 = 3x

minus 2x from both sides

-2 = x

then plug in -2 for x

y = 2(-2) + 1

y = -4 + 1

y = -3

(-2, -3).

How do you divide 2\3 divided by 7\8 using kcf answer

xz_007 [3.2K]

Answer: $\frac{16}{21}$

Step-by-Step Explanation:

KCFmeans: Keep, Change, Flip

Keep: the first fraction

Change: the sign from division to multiplication

Flip: the second fraction

$\frac{2}{3}$ ÷ $\frac{7}{8}$

= $\frac{2}{3} * \frac{8}{7}$ KCF is applied here!

= $\frac{2(8)}{3(7)}$

= $\frac{16}{21}$

steve runs a car wash and detail shop. he determines that 50% of customers get their car washed and vacuumed, while 72% get thei

3241004551 [841]

Answer:

The probability is 0.694

Step-by-step explanation:

Let the probability of getting a car washed be

P(W) = 72% = 0.72

Let the probability of getting a car vacuumed be

P(V) = ?

Probability of getting car washed and vacuumed is P(W n V) = 50% = 0.5

From Bayes’ theorem

P(V|W) is the probability that a customer gets their car vacuumed given that they are getting it washed

So mathematically;

P(V|W) = P(V n W)/P(W)

= 0.5/0.72 = 0.694
