On Call's unit rate is about $2.86 per hour, since $10/3.5 hours= $2.86/1 hour
Talk Time's unit rate is about $2.50 per hour, since $1.25/0.5 hours= $2.50/1 hour

Helen uses 3/4 cup of oil and 1/3 cup of vinegar to make salad dressing. Which is closest to how many times 3/4 is as great as 1
rjkz [21]
3/4 is greater than 1/3

4 x 3 = 12 ( so we shall choose 12 as our new denominator)

1/3 = 4/12  ( multiply 4 top and bottom to get the same denominator)
3/4 = 9/12  ( multiply 3 top and bottom to get the same denominator) 

3/4 is greater than 1/3 by 5/12

hope this helps

7nadin3 [17]

Answer:

x=2,BA=DA which is7

Step-by-step explanation:

5x-3=3x+1

both sides share an angle and B=D right angles

5x-3x=1+3

2x=4

x=4÷2

x=2

BA=5x-3

BA=5(2)-3

BA=10-3

BA=7

DA=3x+1

DA=3(2)+1

DA=6+1

Janna drank 0.7 liter of water before soccer practice and 0.70 liter of water after practice compare the two decimals using grea
maria [59]
0.7 Liters and 0.70 Liters are the same amount.

You can think of them as fractions:  7/10 and 70/100.  Both of these mean the same.  7/10 is the simplest form of the number.

When you put zeros to the right of any number that is to the right of the decimal point, it will not change the value of the number.

0.7 L = 0.70 L

Area of triangle = 1/2 x base x height

so old triangle we have  1/2 x b x h = 48

new triangle has base 3 times as long and height is half as long
 so we would get:

1/2 x (3B) x (1/2H) = area

rewrite as 1/2 x 3/2 x b x H = area

divide by original are os 1/2 x b x h and you end up with 3/2

so new area = 3/2 x old area

new area = 3/2 * 48 = 72 square inches
