Answer:
10 rows with 6 passengers per row
Step-by-step explanation:
Let x be the number of rows and y the number of passengers per row.
Then we can interpret the story as the following two equations:
xy=60
(x+2)(y-1)=60
Solving these two equations:
y=60/x
(x+2)(60/x-1)=60 (substitute y)
60 - x + 120/x - 2 = 60 (multiply by -x)
x² + 2x - 120 = 0 (factor)
(x-10)(x+12) = 0
x = 10
y = 60/10 = 6
and indeed 10 * 6 = 60 and also 12 * 5 = 60
Answer:
I think it would be C.
Step-by-step explanation:
It's obviously not symmetric, so it's not A or D.
You got a 50/50 chance guess.
Answer:
Step-by-step explanation:
Circumference has the formula:
C = 2πr,
Where
C is the circumference
and
r is the radius
Given Circle Y has Circumference of 6, we can find the radius:
C = 2πr
6 = 2πr
r = 6/2π
r = 3/π
So, the radius (r_y) of Circle Y is 3/π, the first choice is right.
1. Add the length of the fabrics together. 2 1/2 + 1 1/4 = 3 3/4. Ciara needs 3 3/4 yards of fabric in total.
2. Subtract 3 from 3 3/4. 3 3/4 - 3 = 3/4. Ciara needs 3/4 yard more of fabric.
3. Multiply $7.98 by 3/4. 3/4 * $7.98 = $5.985. Round to the nearest hundredth to get $5.99.
Ciara needs $5.99 to pay for the rest of her fabric.
