Answer: 11%
Step-by-step explanation:
729-648.81=80.10
What percent is 80.10 of 729
%/100 = is/of (this may help you)
X/100 = 80.10/729 (cross multiplication)
(80.19*100)/729 =

Answer:
y = 10
Step-by-step explanation:
3(y − 8) + 2 = 8
3y - 24 + 2 = 8
3y - 22 = 8
3y = 8 + 22
3y = 30
y = 10

If there are 5380 feet in a mile Express 4000 get In kilometers
please show how you go it
Answer:
ok first there is a problem here there are actually 5280 NOT 5380 feet in a mile. Is this a typo or are you to assume a different length of a mile?
I will stick with the real value of 5280...
5280 feet/ mile * 0.62137119 miles/ km = 3280 f/km
3280 f/km / 4000 feet = .82 km

A class adviser surveyed 35 of his students on what kind of pets they have at home he found out that 15 have dogs 12 have cats and 8 have birds 5 have dogs and cats 4 have dogs and birds and 2 have cats and bids.how many have dogs ONLY
Step-by-step explanation:
With Dogs only: 15 - (5+4) = 6
With Cats only: 12 - (5+2) = 5
With Birds only: 8 - (4+2) = 2
With dogs and cats: 5
With birds and dogs: 4
With cats and birds: 2
With dogs, cats, and birds : 0
Total students surveyed: 35
6 + 5 + 2 +5 + 4 + 2 = 24 students with pets
35 - 24 = 11 students have no pets
Answer:
The answer is only 6 have dogs
Step-by-step explanation:
B + C + D - B∩C - B∩D - C∩D + B∩C∩D + x = 35
8 + 12 + 15 - 2 - 4 - 5 + 0 + x = 35
With Dogs only: 15 - (5+4) = 6
Just in case, we can calculate the others too:
With Cats only: 12 - (5+2) = 5
With Birds only: 8 - (4+2) = 2
With dogs and cats: 5
With birds and dogs: 4
With cats and birds: 2
With dogs, cats, and birds : 0
Total students surveyed: 35
6 + 5 + 2 + 5 + 4 + 2 = 24 students with pets
35 - 24 = 11 students have no pets

3(s-5)/4 -3 = 4s- (s-3)/2
answer fast meenu sister
Answer:
18
Step-by-step explanation:
3(s-5)/4 -3 = 4s- (s-3)/2
open the bracket
3s-15/4-3 =45-s-3/2
3s-15/1=42-s/2
cross multiply
2(3s-15)=42-s
3s-30=42-s
3s+s=42+30
4s=72
s=18
Answer:
s = -45/13
Step-by-step explanation:
3(s - 5)/4 - 3 = 4s - (s - 3)/2
(3s - 15)/4 - 3 = (8s - s + 3)/2
(3s - 15)/4 - 3 = (8s + 3)/2
3(s - 5)/4 - 3 = 3((8/3)s + 1)/2
3[(s - 5)/4 - 1 ] = 3((8/3)s + 1)/2
(s - 5)/4 - 1 = ((8/3)s + 1)/2
(s - 5)/4 - 4/4 = ((8/3)s + 1)/2
(s - 5 - 4)/4 = ((8/3)s + 1)/2
(s - 9)/4 =((8/3)s + 1)/2
(s - 9) = ((8/3)s + 1)(2)
s - 9 = (16/3)s + 2
s - (16/3)s = 6 + 9
(-13/3)s = 15
s = -45/13

IN each figure P bisects the segment. Find the value of each variable
20.
PLEASE HELP!!
Answer:
20.
As P is the mid point so
2x + 3 = x + 7
transpose
2x - x = 7 -3
x = 4
21.
4x + 3 = 8x - 11
transpose
4x - 8x = -11 -3
-4x = -14
x = 14/4
x = 7/2
x can also be 3.5
22.
7x - 3 = 5x + 2
transpose
7x - 5x = 2 + 3
2x = 5
x = 5/2
x can also be 2.5
Answer and Step-by-step explanation:
19.
We see that AB bisects PQ, forming the two angles we are given. These two added together is equal to 180 (because they are supplementary angles, which add up to 180 degrees).
So, add them together, set it to 180, and solve for x.
6 + 2x + 4 = 180
Combine like terms.
10 + 2x = 180
Subtract 10 from both sides from the equation.
2x = 170
Divide by 2 on both sides of the equation.
x = 85 <- This is the answer.
For the following problems, since we know that point P is bisecting the segments, it means that it is splitting the segment in half, creating two equal parts. This means that all we have to do is set the two segments equal to each other.
20.
2x + 3 = x + 7
Subtract 3 and subtract x from both sides of the equation.
x = 4 <- This is the answer.
21.
4x + 3 = 8x - 11
Add 11 and subtract 4x to and from both sides of the equation.
14 = 4x
Divide by 4 from both sides of the equation.
x = [tex]\frac{14}{4} =\frac{7}{2} =(3.5)[/tex] < - This is the answer.
22.
7x - 3 = 5x + 2
Subtract 5x from both sides of the equation and add 3 to both sides of the equation.
2x = 5
Divide both sides by 2.
x = [tex]\frac{5}{2} = 2.5[/tex] <- This is the answer.

Last night, the two dinner specials at Regan's favorite restaurant were salmon filet and steak. The restaurant served 14 specials in all, 7 of which were the salmon filet. What percentage of the specials were salmon filets?
Helpppp pleaseee!
Answer:
50%
Step-by-step explanation:
Find what percent of the specials were salmon filets by dividing the number of salmon filets by the total number of specials:
7/14
= 0.5
So, 50% of the specials were salmon filets.
x= 3(y-b)/m solving for y
its 3(y-b) over m
Answer:
Given:
x = 3(y - b)/mSolving for y in steps
Multiply both sides by m:
mx = 3y - 3bAdd 3b to both sides:
mx + 3b = 3yDivide both sides by 3:
(1/3)mx + b = yy = (1/3)mx + bFind the missing variable if 13-4x=1-x
Answer:
X=4

Find angle A and angle E
Answer:
m∠A = 50°
m∠E = 50°
Step-by-step explanation:
7x - 17 and 2x + 8 are same side exterior angles. They have a sum of 180°.
7x - 17 + 2x + 8 = 180
9x - 9 = 180
9x = 189
x = 21
∠A and 7x - 17 are supplementary. ∠E and 2x + 8 are vertical angles.
m∠A + 7x - 17 = 180
m∠A + 7(21) - 17 = 180
m∠A + 147 - 17 = 180
m∠A + 130 = 180
m∠A = 50
m∠E = 2x + 8
m∠E = 2(21) + 8
m∠E = 42 + 8
m∠E = 50

Write a function to describe the following scenario.
Raw cake batter starts at a thickness of
2 centimeters in a pan but grows at
0.15 centimeters every minute in the oven.
How tall will the cake be after
a certain number of minutes?
Answer:
y = 0.15x + 2
Step-by-step explanation:
Let's say x represents the number of minutes and y represents the thickness of the cake.
No matter what, the cake will start at a thickness of 2 centimeters. Whatever thickness is added on/subtracted starts at 2 centimeters, so y = 2 + or - something.
Next, the batter grows by 0.15 centimeters every minute. This means that every minute, 0.15 centimeters are added to the thickness of the cake. This can be represented by
0.15 * x
Adding these two together, we get
y = 2 + 0.15 * x
y = 0.15 * x + 2
