Answer:

The distance covered by the second cyclist in 45 minutes is (3/4·b + 9) miles

Step-by-step explanation:

The given parameters are;

The distance between the two cyclist when they begin biking away from each other = 7 miles

The first cyclist's speed = 12 miles per hour

The second cyclist's speed = 12 + b miles per hour

Therefore, we have;

The equation for distance covered, d = Speed × Time

The distance covered by the second cyclist in 45 minutes, d_{45 \ minutes} is given as follows;

45 minutes = 3/4 hour

d_{45 \ minutes}  = (12 + b) × 3/4 = (3/4·b + 9) miles

The distance covered by the second cyclist in 45 minutes = (3/4·b + 9) miles.

A rectangular prism is made up of 32 cubes, each measuring 1 4 of a foot per side. What is the volume of the rectangular prism?

Answer:

512ft³

Step-by-step explanation:

A rectangular prism is made up of 32 cubes, each measuring 1 /4 of a foot per side. What is the volume of the rectangular prism?

Since we have 32 cubes with each side = 1/4 foot

= 32 × 1/4 foot

= 8

Hence, the volume of the rectangular prism = 8 × 8 × 8

= 512ft³

Solve the system of linear equations by elimination −2x+3y=7 and 5x+8y=−2
forsale [732]
You would need to make them eliminate so I would multiply the entire first one by 2.5 to make the X's cancel out. So you would end up with -5X+7.5Y=17.5. The X's would cancel and you would be left with 15.5Y=15.5. So Y=1. Then replace Y into one of the equations. I'm going to use the top again. -2X+3(1)=7. Subtract 3 from both sides to get -2x=4. Divide both sides by negative 2 to get X=-2. So the solution would be (-2,1)

sweet [91]

Answer:

$9.86

Step-by-step explanation:

Frist you read the problem and you see that she pays $1.89 for one drink

so you write down $1.89

then 3 cookies for $0.99 so you multiply $0.99 by 3 and you get $2.97

so you write down $2.97

next 2 slices of pizza for $2.50 so you multiply 2 by $2.50 and you get $5.00

so you write that down

lastly you and the answers you wrote down and you get $9.86
