Question 2 : Mixture of Solutions In the chemistry lab, a student has two solutions that contain hydrogen
chloride (HCL) and is mixing them. One solution is 15% HCL and the other is
5% HCL. How many mL of each solution should be mixed to obtain 100 mL of
an 8% HCL solution ? Show your work using the given diagram
15% + 5%
11
8%.

(-1,0) and (4,0) are x-intercepts.

step-by-step explanation:

x-intercepts are all points on the x-axis.

points (-1,0) and (4,0) are both x -intercepts.

e

step-by-step explanation:

an equation by definition has to have two or more variables (x and 2 in this case)

d. $180

step-by-step explanation:

if the dimensions of the room is 9ft by 12 ft, we have the area of the floor as,

so the area of the floor is 108 square feet, converting that into square yards we get,

the cost of carpet is $15 per square yard, therefore the cost of carpet for 12 square yards is,

hence, the cost of carpet is $180.

assuming the dimensions of the room be,

15 ft by 12 ft

so, the area of the floor of that room is,

we can convert 180 square feet into square yards, we know that,

1 sq ft = 0.111 sq yard

so, 180 square feet is,

so the area of floor is 20 square yards.

now, the cost of carpet is 15 dollars per square yard, therefore the cost of carpet for 20 square yards is,

so, it will cost $300.
