Answer: $80
Step-by-step explanation:
You have been told that Sarah ended up paying $60, and you were told before that the charge for a lost book was 75%.
Therefore
$60 = 75%
Now we have to find out what amount of money would be equivalent to 100%:
To do this, find out what amount of money would be equivalent to 25% first.
You can do this by dividing both values by 3.
60 / 3 = 20
75 / 3 = 25
So now $20 = 25%
Now find 100% (which is the original amount) multiply each value by 4 :
$80 = 100%
So the school payed $80 for the book.
hope this helps :)
Answer:
(3x+8)°+(x+4)° = 180,
x=42
Step-by-step explanation:
They are linear pairs, so the two angles are supplementary or add up to 180°.
1. Format the equation (3x+8)°+(x+4)° = 180
2. Simplify like terms 4x + 12 = 180
3. Subtract 12 on both sides, 4x=168
4. Divide 4 on both sides, x=42
5. Answer is x=42
Answer:
8 feet.
Step-by-step explanation:
I chose 20 feet for the whole length.
2/5 of 20 is 8.
Answer:
x-axis = 
y-axis = 
Line x =3 : 
Line x = 6 : 
Step-by-step explanation:
Given lines : y = √x
y = 0
x = 3
To determine the volumes generated we will use the disk method for each of the lines,
attached below is the detailed solution for line x =3 , same procedure will be repeated for each value of x and y to obtain the given results
The volume generated ( x axis )
=
volume generated ( y _axis )
=
Volume about x = 3
= 
Volume about x = 6
=
Answer:
2. A) LNM-ONP
3. B) HI
4. A) GH AND HI
Step-by-step explanation:
2. corresponding sides of similar triangle are proportional and corresponding angles are congruent
3. it seems that triangles are 45-45-90 so GH correspondents with HI
4. JH is geometric mean of line segment making hypotenuse
so JH =
