Answer:
increase because 324 >>>>> 239
percentage: 324/239 = 135%
Answer:
1) 5 2) 6 3) 1.25 or -1.75
Step-by-step explanation:
1. x^2 - 25 = 0
x^2 - 25 = 0
First, add 25 to both sides!
x^2 = 25
Now square root both sides.
x = 5
2. (x-2)^2 = 16
First, square root both sides.
(x-2) = 4
Add 2 on both sides.
(x) = 6
x = 6
3. Quadratic Formula = -b ±
/ 2a
Substitute in:
-6 ±
/ 2(2)
-6±
/ 4
Both forms:
-6 +
/ 4
5 / 4 = 1.25
Negative:
-6 - 1 / 4
-7 / 4 = -1.75
Answer:
t + 0.8 =1.5
Step-by-step explanation:
Our objective is to get to 1.5. we know that part of the distance is 0.8 but we don't know the other half (t).
Answer:
4 tiles
Step-by-step explanation:
Divide 24 by 2 (Coz): 12 tiles
Divide 24 by 3 (Amelia): 8 tiles
Subtract 8 from 12.
12 - 8 = 4
There are 4 more tiles in each of Coz's rows than Amelia's.
Answer:
250 smaller boxes
Step-by-step explanation:
Find the volume of the 2 cuboids.
Formula = Length x width x height
Big cuboid = 50 x 30 x 20 = 30000
Small cuboid = 10 x 3 x 4 = 120
Now divide them.
30000 ÷ 120 = 250 small boxes
