Answer:
About 91 customers would be expected to pay with a credit card.
Step-by-step explanation:
Well you have ro set up a ratio of 16/70 = x/400
This way the amount of people that used a credit card out of all of the people that came and you can figure out the amount of people that will use a credit card out of the 400 people that are expected tho come. You multiply like a butterfly. 70 times x and 400 by 16. Then you will get 6,400=70x divide both sides by 70 and get 91.42=x so if ypu round, 91 people are expected to pay using a credit card out of the 400 customers that are expected to come.
Answer:
(-2,-4), (-1, -1), (0,2), (1,5)(2, 8)
Step-by-step explanation:
you plug x into the equation to get y
Answer:
x=-4/3y+-2/3z+2
Step-by-step explanation:
add +4y to both sides
then add -2z to both sides
then divide both sides by three
Answer:
$0.40 per oz
Step-by-step explanation:
given that the cereal is $3.60 for a 9 oz box
i.e
9 oz ----> costs $3.60
1 oz ----> costs $3.60 ÷ 9 = $0.40
hence the unit rate is $0.40 per oz
To find the perimeter, you need the lengths of all 3 legs,
and then you add them up.
Can you find the lengths of the other 2 sides of that triangle ?
Here are a couple of factoids I learned in 1954 and I never forgot:
In a 30°- 60°- 90° right triangle . . .
-- the side opposite the 30° angle (the shorter leg)
is 1/2 the length of the hypotenuse,
and
-- the side opposite the 60° angle (the longer leg)
is (1/2 the length of the hypotenuse) times (√3).
If you have a 30°- 60°- 90° triangle and you know the length
of any one side, then you can find the lengths of the other
two sides with these amazing factoids.
