Answer:
x = 2.4/20= 0.12
Step-by-step explanation:
Multiply both sides by 4 to eliminate the fraction 1/4:
1 20
--- = ------
x 2.4
Next, we cross-multiply. This eliminates the fractions:
20x = 2.4
Dividing both sides by 20 results in an equation for x: x = 2.4/20= 0.12
Answer:
put x=3 in equation we get
18-1
17 is the answer
Answer:
QRST becomes Q prime, R prime, S prime, T prime.
Step-by-step explanation:
Any figure that is rotated, translated or reflected on the corrdinate plane is considered a prime (as long as it is congruent (the same as, or equal to) with the original). The apostrophe stands for prime.
Ex. If you reflect triangle ABC across one of the axes, the original triangle will continue being ABC, while the reflection would be A' B' C' (or A prime, B prime, C prime). I hope this helps :)
If the variance is 5 then the standard deviation is √5.
If Z is the score then Z=(8-16)/√5=-3.58 approx.
The length is 10 meters.
A square has 4 sides that are all the same length. This means that if one side was, say, 20 cm, every side would be 20 cm.
Recall that to solve for area, you simply have to multiply the length by the width. Since a square has all equal sides, the length and the width will be equal.
Since we know that the area is 100 m^2, we can make an equation:
n * n = 100
n = sqrt(100)
n = 10
