In science class, Scott estimates the mass of a sample to be 109 grams. The actual mass of
the sample is 104 grams. Find the percent error of Scott's estimate. Round your answer to
the nearest tenth.
Answer:
Percent of error = 4.80% (Approx)
Step-by-step explanation:
Given:
Mass of sample = 109 gram
Actual mass of sample = 104 gram
Find:
Percent of error.
Computation:
Error = Mass of sample - Actual mass of sample
Error = 109 gram - 104 gram
Error =5 gram
Percent of error = (Error / Actual mass of sample)100
Percent of error = (5 / 104)100
Percent of error = 4.80% (Approx)

Solve the following equation. Then place the correct number in the box provided. 7x/15-1=22
x=?
Answer:
44
Step-by-step explanation:
First you have to make sure that you move everything from one side to the other and set the equation equal to zero. Then you have to simplify the equation as much as you can so you get:
x/14
7 * (x/14)
eventually you get
(x-22)/2 =0
from there you can solve for 44

A chemist is adding pure (100%) acid to a 12 liter solution that is 15% acid in order to increase it to 49% acid. How much pure acid must she add?
How many ounces of 35% ethanol must be added to a 23 ounce mixture that contains 26% ethanol in order to obtain a mixture of 30.86% ethanol?
How many liters of 30% acid must be added to 10 liters of 53.66% acid in order to obtain a mixture that is 43% acid?
Answer:
1) 8 liters of pure acid
2) 27 liters of 35% ethanol
3) 8.2 liters of 30% acid
Step-by-step explanation:
The inicial amount of acid is 15% of 12 L, and the inicial volume is 12L.
Adding 'x' L of 100% acid, we have the amount of acid equal to 12 * 0.15 + x * 1, and the volume of 12 + x. The concentration is the amount of acid over the volume, so we have that:
(12*0.15 + x) / (12 + x) = 49/100
(1.8 + x)*100 = (12 + x) * 49
180 + 100x = 588 + 49x
51x = 408
x = 8 liters of pure acid
Similar to the solution above, for the second question we have:
(23*0.26 + 0.35*x) / (23 + x) = 30.86/100
(5.98 + 0.35*x)*100 = (23 + x) * 30.86
598 + 35x = 709.78 + 30.86x
4.14x = 111.78
x = 27 liters of 35% ethanol
For the third question, we have:
(10*0.5366 + 0.3*x) / (10 + x) = 43/100
(5.366 + 0.3x)*100 = (10 + x)*43
536.6 + 30x = 430 + 43x
13x = 106.6
x = 8.2 liters of 30% acid
Which equation represents the graphed function?
O y=-3x + 3
O y= 3x - 3
Oy= 3x - 1/3
O y=-1/3x+3
Answer:
y = -1/3x+3
Step-by-step explanation:
use slope formula y₂-y₁/x₂-x₁ plug in the values and get the answer. y2 is y coordinate of the second point and and y1 is the y coordinate of the first point same with x2 and x1
The equation that represents the graphed function would be; y = -1/3x+3
We know that the slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
where (x₁, y₁) and (x₂, y₂) are the two points that trying to find the slope between.
Now plug in the values and get the answer.
y2 is y coordinate of the second point and and y1 is the y coordinate of the first point same with x2 and x1
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( 3-2) / ( 0-3)
m = -1/3
The equation will be y=-1/3x+3

Answer:
Step-by-step explanation: since ab||ef, line cd is a transversal
x+35°=85° (alternate interior angles)
x=85-35
x= 50°
taking bd as a transversal
y= 35° (alternate interior angles)
taking bz as a transversal
y+z+40°= 180° (interior angles on the same side of the transversal)
z+35°+40°= 180°

Answer:
x = 50 degree found by working out c and d
y = 35 degree
z = 105 degree
Step-by-step explanation:
c is solved 180-85 = 95 as all straight lines equal (180)
d is solved 85-35 = 50 as it is alternate of c (85)
x is found 85 - 35 = 50 degree as it is part of d and not supplementary
y is found 180-95 = 85 then 85-50 = 35 as angles are adjacent and add up to 180 degree.
z is found 180-75 = 105 as angles are adjacent and add upto 180 degree but z is also alternate to missing c angle

Step-by-step explanation:
Since these angles are supplementary (meaning they have a sum of 180 degrees) we get 3a + 2a + 4a = 180° which simplifies to 9a = 180 and then a = 20°
Answer:
a = 20
Step-by-step explanation:
The angles form a straight line, which is 180 degrees
3a + 2a + 4a = 180
Combine like terms
9a = 180
Divide by 9
9a/9 =180/9

Answer:
Mini golf: $10.00, batting cage: $2.50
Step-by-step explanation:
We have that 5 mini golf + 4 batting = 60, and 3 mini golf + 6 batting = 45.
Let m=mini golf price, and b=batting cage price.
Then 5m+4b=60 and 3m+6b=45.
We can multiply the first equation by 3 and second by 5 to get
15m+12b=180
15m+30b=225
Subtract the two to get -18b=-45, so b=45/18=$2.50
Then m=$10 if you substitute b back in the first equation.

A triangle on a coordinate plane is translated according to the rule T-8,4(x, y). Which is another way to write this rule?
A (x,y) - (x + 4, y - 8)
B (x,y) - (x - 4, y - 8)
C (x, y) - (x - 8, y + 4)
D (x,y) - (x + 8, y - 4)
Answer:
CStep-by-step explanation:
(x, y) → (x – 8, y + 4)A triangle on a coordinate plane translated according to the rule [tex]T_{-8,4}(x,y)[/tex]can also be written as [tex](x,y)[/tex] → [tex](x-8,y+4)[/tex] according to the translation rule.
What is translation rule ?According to translation rule [tex]T_{a,b}(x,y)[/tex] tells that translation of a point (x,y)
by (a,b) is given by [tex](x,y)[/tex]→[tex](x+a,y+b)[/tex].
How to use translation rule to find the answer?Given that [tex]T_{-8,4}(x,y)[/tex], a=-8 and b=4
Putting in the values given in the question to the translation rule we get
[tex](x,y)[/tex]→[tex](x+(-8),y+(4))[/tex]
[tex](x,y)[/tex]→[tex](x-8,y+4)[/tex]
Hence we get triangle on a coordinate plane translated according to the rule [tex]T_{-8,4}(x,y)[/tex]can also be written as [tex](x,y)[/tex] → [tex](x-8,y+4)[/tex]. Answer C is correct.
