Answer:

−9.333

Step-by-step explanation:

(1): "6.75" was replaced by "(675/100)"

(675/100)+3/8*x-((13)*1/4)=0

Simplify 1/4

675 3 1

(———+(—•x))-(13•—) = 0

100 8 4

Simplify —

Equation at the end of step

675 3 13

(——— + (— • x)) - —— = 0

100 8 4

STEP

Simplify ——

Equation at the end of step

27 3x 13

(—— + ——) - —— = 0

The following graph shows the relationship between cost and revenue for a manufacturer of lab coats.

nataly862011 [7]

Answer:

Option a.

I and III

Step-by-step explanation:

Observing the graph

For n=400 coats

The cost is about $2,200

and

The revenue is less than $1,400

Substitute the value of n=400 in each equation to find the solution

I Cost 1.5(400)+1,600=$2,200 ----> is ok

II Cost 4.5(400)+1,600=$3,400 ----> is not ok ( is greater than $2,200)

III Revenue 3.25(400)=$1,300 ----> is ok ( is less than $1,400)

IV Revenue 5.75(400)=$2,300 ----> is not ok ( is greater than $1,400)

therefore

The solution is I and III

Question 15 of 43

Andrews [41]

Answer:

Option A

Step-by-step explanation:

$\frac{12}{25} \times \frac{11}{24} \times \frac{10}{23} \times \frac{9}{22}$

we start with 12 red marbles out of 25 marbles, that's the probability for the first.

in the second step we have one red marble less, wich also means one marble less overall

and so on

$\frac{12 \times 11 \times 10 \times 9}{25 \times 24 \times 23 \times 22}$

$= \frac{11880}{303600}$

can be reduced by 1320 (step by step) to

$\frac{9}{230}$

Musya8 [376]

Answer:

3000 is your answer

Step-by-step explanation:

The 3 in the hundreds place if the number 587,349 has a value of 300. This 300 is 1/10 the value of the number you're looking for, so if x is the number you're looking for, then

$300 = \frac{1}{10} x$

$300 \times 10 = \frac{1}{10} x \times 10$

$3000 = x$

x is your answer.
