B) 31%
For the first problem, we know that 25 out of 80 tokens are black. To find the percentage all we have to do is divide 25 by 80, which equal 0.31. To convert this to percentage form, you move the decimal two places to the right, giving you 31%.
And for the second problem you do the same thing. Divide 5 by 16, giving you 0.31. Convert that into percentage, also giving you the percent of 31%.

Answer:
Lines are perpendicular to each other .
Step-by-step explanation:
Standard equation of line is : y = mx + c, Where m represents the slope
Given Equations :
[tex]y = -5x + 1\\\\Slope , m_1 = -5[/tex]
[tex]y = \frac{1}{5}x +1\\\\Slope, m_2 = \frac{1}{5}[/tex]
Two lines are parallel if the slope of the lines are same.
Two line are perpendicular if the product of the slope = - 1
Clearly slopes are not equal , therefore the lines are not parallel.
product of the slope is - 1, therefore the lines are perpendicular.
[tex]m_1 \times m_2 = -5 \times \frac{1}{5} = - 1[/tex]

Answer:
[tex]\text{A. }25/33,\\\text{B. }1/3, \\\text{C. }1/33, \\\text{D. }25/9[/tex]
Step-by-step explanation:
Recall that [tex]\frac{x}{9}=0.\overline{x}[/tex] for [tex]x\in (1, 8)[/tex]. If multiple digits are repeating, increase the number of nines in the denominator as applicable.
Therefore, we have:
Part A:

Part B:
"3" is repeating:
[tex]\rightarrow \frac{3}{9}=\boxed{\frac{1}{3}}[/tex]
Part C:
"03" is repeating:
[tex]\rightarrow \frac{03}{99}=\frac{3}{99}=\boxed{\frac{1}{33}}[/tex]
Part D:
"7" is repeating, but there is a terminating decimal 2.0 with it ([tex]2.\overline{7}=2.0+0.\overline{7}[/tex]):
[tex]2+\frac{7}{9}=\frac{18}{9}+\frac{7}{9}=\boxed{\frac{25}{9}}[/tex]

Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.
Option (4) is correct.
What is a Triangle?A triangle in geometry is a three-sided polygon with three edges and three vertices.
As per the given data:
We are given two angles for each pair of triangles, and we have to find out which of the pair of triangles are similar.
For any two triangles to be similar, it must have 2 angles which are having the same measure.
For, Triangle 1: 55°, 45° and Triangle 2: 55°, 80°
Only one angle is same, hence not similar.
Triangle 1: 103°, 32° and Triangle 2: 103°, 25°
Only one angle is same, hence not similar.
Triangle 1: 73°, 47° and Triangle 2: 47°, 30°
Only one angle is same, hence not similar.
Triangle 1: 105°, 23° and Triangle 2: 52°, 105
By using angle sum property in Triangle 1 the remaining angles is:
= 180 - (105 + 23) = 52°
By using angle sum property in Triangle 2 the remaining angles is:
= 180 - (52 + 105) = 23°
2 angles are same, hence similar.
Triangle 1: 99, 41° and Triangle 2: 40°, 99°
Only one angle is same, hence not similar.
Hence, Triangle 1: 105°, 23° and Triangle 2: 52°, 105 are similar.

what is the solution to this system of equations?
Answers
Answer:
(0, -5)
Step-by-step explanation:
Multiply both sides of the second equation by 6 to get 6y=3x+30. Then, subtract the second equation from the first to cancel out the x's. y-6y=-5y, 3x-5-3x-30=-25. -5y=-25, so y=-5. Substitute -5 into the first equation to get 3x-5=-5, add five to both sides: 3x=0, divide by 3: x=0. The ordered pair is (0, -5). Hope this is correct and helps! :)

A person's Body Mass Index (BMI) is a measure of the mount of fat in their body. The relationship between antioxidant food consumption per day in cups and the BMI of an individual is modeled by the following line of best fit: y = -0.1x + 22. Interpret the slope and intercept of the trend line within the context of the data.
Answers
Answer:
Check explanation
Step-by-step explanation:
Given:
y = -0.1x + 22
Where,
y = BMI of an individual
x = antioxidant food consumption per day in cups
Equation of a slope
y = mx + c
Where,
m = slope
c = y - intercept
Therefore,
From the equation
y = -0.1x + 22
slope, m = -0.1
y - intercept, c = 22
Answer:
The y-intercept tells us that a person who doesn’t have any antioxidant foods can expect to have a BMI of 26. For every cup of antioxidant food that is consumed one can expect to lower their BMI by 1.2.

Answers
Answer:
The second option
Step-by-step explanation:
To solve this, you should convert both rates to equations, with y being the total fare, and x being the number of miles. The rates of both use the format y=mx+b (where m is the amount per mile and b is the flat rate, or original rate).
By subbing in the values for m and b, you get y=2x+4 for A and y=3x+5 for B. This is the second option.

If a ring costs a jeweler $1500, at what price should it be sold to yield a profit of 50% on the selling price?
Answers
Answer:
$2250
Step-by-step explanation:
selling the ring at 100% of $1500 would equal 1500 and yield no profit
therefore, you must sell the ring at 150% (where 100% covers the cost and the additional 50% provides the profit) of 1500
1.5 x 1500 = 2250
