Answer: p=0.87 (density of oil), m=37.5 (mass of liquid), v=11.92 (volume of liquid)

Step-by-step explanation:

p=m/v

p=43.5/50

p=0.87 (density of oil)

m=pv

m=2.5x15

m=37.5 (mass of liquid)

v=m/p

v=65/5.45

v=11.93 (volume of liquid)

Answer:

2.) v = 50ml

m = 43.5g

d = m/v

d = 43.5g/50ml

D = .87g/ml

3.) d = 2.5g/ml

v = 15ml

2.5g/ml = m/15ml

m = (2.5)(15)

M = 37.5g

4.) d = 5.45g/ml

m = 65g

5.45 = 65/v

v = 65/5.45

V = 11.93ml

Still can’t get the answer

Eddi Din [679]

Answer:

Arliss needs $4 \frac{1}{3}$ yards more.

Step-by-step explanation:

We can look at the fractions $2 \frac{1}{3}$ and $3 \frac{1}{3}$ and add them up.

Looking at the whole numbers, $2+3=5$ .

Looking at the fractional parts, $\frac{1}{3} + \frac{1}{3} = \frac{2}{3}$ .

So all together, she currently has $5 \frac{2}{3}$ yards.

If she wants to get to 10, we need to find how many more yards we need.

Let's level it out quickly - having $\frac{1}{3}$ more of a yard will give is 6 yards.

$10-6=4$ , so in total we added

$4 \frac{1}{3}$ more yards.

So she needs $4 \frac{1}{3}$ more yards.

Hope this helped!

Solve the inequality 2x + 7 - 3x < 13 +2X. You must show your work and describe the graph of the solution on the number line.

kozerog [31]

Cancel equal terms on both sides of inequality

7-3x < 13

move constant to the right side and change its sign

-3x<13-7

subtract the numbers

-3x<6

divide both sides of inequality by -3 and flip the inequality sign

answer is: x>-2
