7/8 = 21/24
1/6 = 4/24
21/4 = 5.25 round to 5 because there's no 0.25 recipe
So she can make her recipe 5 times. Hope this helped!!
Use the PEMDAS rule you learned in elementary. First do the exponent that is -9 with 10 then multiply the denominator ( the bottom of fraction) and lastly divide 0.09 divided by what the denominator is.
Answer:
B) 6 tan(35°)
Step-by-step explanation:
from the right angle tan° = opposite / adjacent
therefore tan (35°) = (x) / 6
by multiplying 6 to both sides
tan (35°) * 6 = (x) / 6 * 6
therefore (x) = 6 tan (35°)
90 x 0.9 (90%) = 81 students
This means 81 students are enrolled in health.
Hope this helps :)
39 has factors (1 * 39) & (3 * 13)
Here we'll try
m + n = 13
m - n = 3
2m = 16
m = 8
2n = 10
n = 5
2mn = 2 * 8 * 5 = 80
So this choice is no good.
Let's go with
m + n = 39
m - n = 1
2m = 40
m = 20
2n = 38
n = 19
Thus
x = 20² - 19² = 39
y = 2 * 20 * 19 = 760
z = 20² + 19² = 761
