Answer:
The rates are 1/2 yards per hour
Step-by-step explanation:
Here, we want to calculate the rate of change in the amount of yarn
We start by calculating the difference between what we had initially and what we have now
That will be;
3 3/4 - 1 1/8
= 15/4 - 9/8 = 21/8 yards
So we now divide this by the number of hours
21/8 yards divided by 51/4
= 21/8 * 4/21 = 1/2 yards per hour
Answer: 8.4
Step-by-step explanation:
Answer is p (9,5)=9*8*7*6*5=15120

Perpendicular = 15cm
Base = 36cm
Let Hypotenuse = X
By using Pythagoras theorem
15^2 + 36^2 = x^2
x^2 = 1296
x = ± 39
since length cannot be negative Length of missing side = 39
see diagram in attachment
a rhombus is a 4 sided figure with 4 equal length sides
so if we can find the length of 1 side and multiply it by 4, we get the perimiter
you can draw 2 lines to make 4 similar triangles
we can see that you can use pythagorean rule to get the length of the hypotonuse of one triangle so so perimiter is 4*5=20 units
or you can use distance formula which is basically the pythatorean theorm
from W to X, that is from (-3,1) to (1,4)
4*5=20, so perimiter is 20 units
