Answer:450
Step-by-step explanation: If you add 150 to 150 that will give you 300.If you add 300 to 100 that will give you 400.Finally if you add 400 to 50 that will give you 450.
Your answer is: 450 students
Answer:
Step-by-step explanation:
We are going to use the identity
because this identities right hand side matches your expression where
and 
.
So we have that 
is equal to .
Answer:
79
Step-by-step explanation:
60<xy<100
y -2 =x
if it is prime
y cannot be even
so y could be 1,3,5,7,9
x would then be 9,1,3,5,7
but to be between 60 and 100
x must be 7 or 9
so the number must be 79 or 57
57 is not prime so
the number is 79
((2t+10) / 2) + ((3t-15) / 2) + (3s) = 180
((2t+10) / 2) + ((3t-15) / 2) + (4r) = 180
((2t+10) / 2) + ((3t-15) / 2) + (3s) = ((2t+10) / 2) + ((3t-15) / 2) + (4r)
(2t+10) = (3t-15) t=25
2*25+10= 60 , 3*25-15=60
60+60= 120 , This rectangle has a total of 360 degrees
360 - 120 = 240
240/2 =120
120/ 4 = 30 , 120/3 = 40
r=30 s=40
3 3/8 · 4 1/3
To make this easier to solve, let's change the mixed numbers into improper fractions. This is done by multiplying the denominator (8) by the whole number (3) and then adding that to the numerator (3), keeping the denominator the same. Do the same thing with the second fraction.
27/8 × 13/3
Now you can multiply.
(27 × 13)/(8 × 3)
351/24
Now think of how many times 24 can go into 351. You can find this out by plugging it into a calculator. You should get 14.625. Since we need a whole number though, round down to 14.
14 × 24 = 336
This means that there will be 15 left over.
So far the fraction looks like this:
14 15/24
The last thing you need to do is simplify. A number that can go into both 15 and 24 is 3, so divide them by that.
14 5/8
The answer is
D. 14 5/8
