Answer:

I can tell you the first one and you can figure it out from there. 70 is 40% persent of what number? Well, we can chop 40% to 20% and chop 70 in half and we get 35. So 35 = 20% So we multiply 35 by five, and get 175. So 70 is 40% of 175.

A family on a trip budgets $1,000 for meals and gasoline. If the price of a meal for the family is $50 and if gasoline costs $3.
galben [10]

Answer:

They can buy 13meals if they buy 100 gallons of gasoline.

Step-by-step explanation:

3.50 PER gallon so 1 gallon is $3.50

if they buy 100 gallons you have to multiply 3.50 by 100 which gives you 350. you subtract 350 from 1000 so 1000-350 and get 650. now, you divide 650 by 50 because each meal is $50. And you get 13 so there you have it.

Choose all that state the correct unit rate for each situation. 100 POINTS ASAP K12
Lorico [155]

Answer:

Please see the answers below:

Step-by-step explanation:

The wrong answers are deleted only the correct answers are listed below:

  • Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
  • Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
  • Claire saves $320 in 16 weeks. The unit rate is $20 per week.

  • % increase in price of gas = [(New Price - Original Price) / Original Price] x 100

% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100

% increase in price of gas = [$0.3 / $2.18] x 100

% increase in price of gas = 13.76%

If a rectangular area is rotated in a uniform electric field from the position where the maximum electric flux goes through it t
Greeley [361]
With a uniform electric field, flux go along parallel paths, then flux is therefore proportional to the cosine of the angle rotated.
0 degree rotation => cos(0)=1 => 100% of flux.
60 degrees rotation => cos(60) => 0.5  => how many % of flux?

If B is the midpoint of AC, and AC=8x-20. Find BC<br> AB=3x-1<br> Show all work
exis [7]
First we know that:
AB+BC=AC
now , since B is the midpoint of AC, this means that AB=BC
therefore,
AB+BC=AC can also be written as
AB+AB=AC
3x-1+3x-1=8x-20
6x-2=8x-20
-2+20=8x-6x
18=2x
x=9

therefore:
AB=3(9)-1=27-1=26
AC=8(9)-20=52
BC=AB=26
