5x^2 -15x-140
5(x² -(3x) -28)
5(x² +(4x-7x)-28)
5(x(x+4) -7(x+4)
5(x-7)*(x-4)
Let us say ,
x=number of students who passed
y=number of students who failed
total number of students =276
x+y=276..................(1)
We are given 5 times the number of students passed as failed.
x=5y.............(2)
plugging value of x from (2) in (1),
5y+y=276
6y=276
y=46
x=5y=46*5=230
x=number of students who passed=230
Answer:
answer a because -15/8 is -1.875
Answer:
The formula for the volume of a cylinder is pi*r^2*h
r=radius= 1/2 diameter
h= the height
pi=3.14...
just get the height and plug it in
Step-by-step explanation:
Answer:
<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between, we can calculate for ∠A using the sine law:
</em>
<em>
</em>
<em>b / sin B = a / sin A
</em>
<em>
</em>
<em>2.45 / sin 60 = 2 / sin A
</em>
<em>
</em>
<em>sin A = 0.707
</em>
<em>
</em>
<em>A = 45˚
</em>
<em>
</em>
<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>
