In 3/4of a minute he crawls 3/8ft
4/4(1)=3/8+(1/4x3/8) so in 1min= he crawls 3/64ft

3/4min=3/8ft
4/4(1)=3/8+(1/4x3/8)
1min=3/64ft

pretty sure i did that right...if not I'm sorry

Answer:

vol = 96

Step-by-step explanation:

Area of a triangle = 1/2 * b * h

b = 4

h = 6

A = 0.5 * 4 * 6

A = 12

length = 8

vol = Area * length

vol = 12 * 8

vol = 96

A carpenter has boards of lengths 24, 40, and 48 inches that must be cut into smaller boards of equal length, with no scrap wood

bulgar [2K]

It would be 8 inches, because for this you just have to find the greatest common factor between all three numbers which is 8

Answer:

C : 4.29

Step-by-step explanation:

First find the distance she walks on the weekdays.

0.55*5=2.75

Now you find out how much she walks on one weekend and multiply that by two.(Saturday and Sunday)

0.55*1.4=0.77

0.77*2=1.54

Now add the two numbers

1.54+2.75=4.29

Hope I helped!!!

Have a great day!

Nancy’s van traveled 84 miles on 6.5 gallons of gas. At this rate, how many gallons of gas would be needed to travel 126 miles?

nikklg [1K]

126/84=1.5
1.5*6.5=9.75
9.75 gallons of gas are needed to travel 126 miles.

Solve one, any question you want, please show work,

Answer:

Step 1: Variables are q for quarters and d for dimes. So d = dimes and q = quarters

Step 2: The two equations that form a system of equations are:

$\left \{ {{0.1d+.25q=3.70} \atop {d+q=19}} \right.$

Step 3: Work is shown on the attachment and on the step-by-step explanation

Step 4: Given the context of the problem, the solution of the amount of dimes and quarters, which is 7 dimes and 12 quarters, is needed to satisfy both systems to concur that there was 7 dimes and 12 quarters in a sum of money that amounted to $3.70 with 19 coins in total.

Step-by-step explanation:

Step 1: To first attempt to solve this, we must have to set up two variables for the amount of value a quarter and a dime has. So since a quarter is worth 0.25¢ in and a dime is worth 0.10¢, then we can set up one of the equations to be:

$0.1d + .25q = 3.70$

And we set it to equal the $3.70 because that's the amount that the sum of money totals to.

Step 2: Now to get the other side of the equation, we use the variables again, d and q and set that to equal 19 because that is the amount of coins that there is in total.

Step 3: Now that we have both equations, we can solve the problem now.

$\left \{ {{0.1d+.25q=3.70} \atop {d+q=19}} \right.$

Let's first solve this equation by setting one of the side's variables the same absolute value, but not the same integer value so that we can cross it off. I will choose the equation $d+q=19$ to be multiplied by -.1 so that we can cross off both 0.1d and -0.1d after the result of the multiplication:

$\left \{ {{0.1d+.25q=3.70} \atop {-.1d+-.1q=-1.9}} \right.$

Now, lets cross off everything that we can, and add up the variables together. This includes adding .25q + (-.1q) and adding 3.70 + -1.9.

Now we have:

$\left \{ {{.25q=3.70} \atop {-.1q=-1.9}} \right.$

Now, what we do from here is add the left side and the right side side to get one equation, which is:

$.15q=1.8$

Finally, we divide both sides to get q=12, which means that there are 12 quarters. Since there are 19 coins in total, we can subtract 12 from 9 to get the remaining amount of dimes, which is 7.

In conclusion, q=12 and d=7.

My written work is also provided in the attachment!!!

Step 4: What does this mean in the context of the question?

This basically means that the solution of the amount of dimes and quarters, which is 7 dimes and 12 quarters, is needed to satisfy both systems to concur that there was 7 dimes and 12 quarters in a sum of money that amounted to $3.70 with 19 coins in total.

In simpler terms, this means that we need 7 dimes and 12 quarters to satisfy that there was a sum of money that amounted to $3.70 with 19 coins in total .
