We are given a figure with several given expressions:

EK = x + 5
KJ = x +5
FG = 2x
GH = 3x - 5

Assuming that the triangle is equilateral:

equate GH = FG

3x - 5 = 2x

solve for x

x = 5

therefore, one side of the triangle:

x + 5 + x + 5 = 20

and the perimeter of the equilateral triangle is

3*one side = 3 * 20 units

Thus, Perimeter = 60 units. <span />

In tests for intoxication, blood alcohol levels are expressed as percentages by volume. A blood alcohol level of 0.080% by volum
GaryK [48]

Answer:

The required volume is 5 ml.

Step-by-step explanation:

Given : In tests for intoxication, blood alcohol levels are expressed as percentages by volume. A blood alcohol level of 0.080% by volume means 0.080 mL of ethanol per 100 mL of blood and is considered proof of intoxication. If a person's total blood volume is 5.0 L.

To find : What volume of alcohol in the blood gives a blood alcohol level of 0.100 % by volume?

Solution :

According to question we use the formula,

\text{Present Volume}=\dfrac{\text{Vol}_{\text{Alcohol}}}{\text{Vol}_{\text{total}}}\times 100\%

The percentage of a blood alcohol level is 0.100%

The total volume of the blood is V=5L=5000 ml.

Substitute the value in the formula,

0.100=\dfrac{\text{Vol}_{\text{Alcohol}}}{5000}\times 100

\frac{0.100}{100}=\dfrac{\text{Vol}_{\text{Alcohol}}}{5000}

\text{Vol}_{\text{Alcohol}}=\frac{0.100\times 5000}{100}

\text{Vol}_{\text{Alcohol}}=5

Therefore, the required volume is 5 ml.

devlian [24]

Darling, this problem is quite simply addition. You add 18 to 1328. 1328 + 18. we add the eights first. 8 + 8 equals 16. The 6 stays and we carry the one. 1 + 2 is 3. And then we add our carried 1 to make 4. So, the answer is 1346. I hope this helped!
