Natasha_Volkova [10]

The probability that two events occur is equal to the product of the individual events happening or occurring. For this item, we let x be the probability that is unknown such that the relationship between them may be expressed as,
(3/5)(x) = 33/95
The value of x from the equation is 11/19.

Compare the fraction 1:24,000 to the fraction 1:3,168,000; which is the largest rational number

gulaghasi [49]

Answer:

$\frac{1}{24,000}$

Step-by-step explanation:

we know that

When we compare positive fractions with the same numerator, the largest rational number will be the fraction with the lowest denominator

In this problem we have

$\frac{1}{24,000}$ and $\frac{1}{3,168,000}$

Both numerator are equal

Compare the denominators

$24,000 < 3,168,000$

therefore

$\frac{1}{24,000}$ is the largest rational number

Could yall solve this and tell me how you did it I'm so confused 5/6 ÷(-11/7)=

Sedbober [7]

the answer is -35/66

to divide fractions you take the reciprocal of the second fraction (switching the numerator and denominator) and multiply it so the equation turns into

5/6*(-7/11) = -35/66

hope you understand now

Which ordered pair makes both inequalities true?

kvasek [131]

Answer:

(3, 0)

Step-by-step explanation:

Given the inequality y > -2x + 3 and y ≤ x - 2

The graph of the inequalities are plotted using the geogebra graphing online calculator.

The portion of the graph that is shaded with dark blue, represents the portion that supports the equation.

All the ordered pair points given in the question are also labelled in the graph.

From the graph we can see that only point (3, 0) falls in the area that supports the equation. Hence (3, 0) makes both inequalities true.

Each week, Darin's Lawn Service mows 90 lawns in 45 hours at a housing c

sweet [91]

9514 1404 393

Answer:

6 h

Step-by-step explanation:

The bottom number in the table is half the top number. The missing value is 6 (hours).

I like to put the variable in the numerator of a proportion. Here, we can write it as ...

t/12 = 45/90

Multiplying by 12 gives ...

t = 12(45/90) = 12(1/2) = 6

It will take Darin 6 hours to mow 12 lawns.
