Agasoline container that is 1/8 full can fill up 2/8 of a gas tank. how many containers are needed to fill up the gas tank.

Step-by-step explanation:

Given that gasoline container is full of = 1/8 of the tank.

We need to fill tank upto = 2/8th of the tank.

Therefore,

Number of containers are needed to fill up the gas tank =

Plugging values in above formula, we get

Number of containers are needed to fill up the gas tank = .

Converting division into multiplication, the fraction 1/4 would flip to 8/1.

Therefore,

=

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
