Answer:
Bill's bar has 57.3 grams of cocoa.
Step-by-step explanation:
The math part that your question is asking is: What is 69% of 83?
In order to use the percent 69% in a calculation, you need to change it to a decimal.
69% is 0.69
You move the decimal to the left, two places.
69% is 69.% If you don't see a decimal to start with and it is a whole number, then the decimal is starting on the right.
Move it two places to the left, you get
.69
Now MULTIPLY.
.69 × 83
= 57.27
ROUND your answer to the nearest tenth. That means only one digit to the right of the decimal.
57.27 rounds to 57.3

b. Does the lower median age for blacks necessarily mean that blacks die younger than whites? Why or why not?
c. How might it be possible for blacks and whites to die at approximately the same age, but for the median age for whites to be higher?

An angle measures 78° less than the measure of its complementary angle. What is the measure of each angle?
Answer: 6 and 84 degrees
Step-by-step explanation:
Let the measure of the angle = x.
Since complementary angles sum to 90 degrees,
x + (x+ 78) = 90
2x + 78 = 90
2x = 12
x = 6.
Therefore the angles are 6 and 84 degrees.
f(x) = 7x+2 what's the value of f(7)
Are the polygons similar? If they are, write a similarity statement. The figures are not drawn to scale.
Based on the SAS similarity theorem, both triangles are similar.
Similarity statement is: ΔSTV ~ ΔPQR by SAS Similarity Theorem.
What are Similar Polygons?Similar Polygons have different size but the same shape, and as such, the ratio of their corresponding side lengths are equal, while their corresponding angles are congruent.
Based on the SAS similarity theorem, two triangles are similar to each other if they have two pairs of corresponding sides that are proportional and an included pair of angles that are congruent.
In ΔSTV and ΔPQR:
m∠S ≅ m∠P = 86° (one pair of included congruent angles)
ST/PQ = SV/PR = 0.67 (proportional sides).
Therefore, based on the SAS similarity theorem, both triangles are similar.
Similarity statement is: ΔSTV ~ ΔPQR by SAS Similarity Theorem.

y=mx+b
Answer:
y = -2x - 3
Step-by-step explanation:
in the equation y = mx + b,
m = slope b = y-intercept
The y-intercept is provided in the point, (0, -3), because that is where it crosses the y. You're y-intercept is -3
Now you need to find slope. You need to find the difference between these two points to find slope.
[tex]-2+0 = -2[/tex]
[tex]1-3=-2[/tex]
so your slope is going down by 2 and to the left by 2.
Hope this helps! Might be wrong. Try with another example and tell me if it works. <3
Answer: B
Step-by-step explanation:
m is the value of the slope between the two points on the graph
If the two coordinates is (x1,y1) and (x2,y2), the slope is (y1-y2) / (x1-x2)
So the slope for this question is (1-(-3)) / (-2-0) = -2 so the answer is B

(m . n)(7)
A. Undefined
B. 1
C. 0
D. -1
The function value of (m × n)(7) is: C. 0.
How do we Find a Function Value?To find the value of a function, plug in the given value of x and simplify.
Given:
m(x) = x - 7
n(x) = 1/x + 7
Find (m × n)(7)
(m × n)(7) = (x - 7)(1/x + 7)
Plug in x = 7
(m × n)(7) = (7 - 7)(1/7 + 7)
(m × n)(7) = (0)(1/7 + 7)
(m × n)(7) = 0
Therefore, the function value of (m × n)(7) is: C. 0.

24 is 3/4 of ___
Find the answer
Answer:
24 is 3/4 of 32.
Step-by-step explanation:
if you understand:
24 divided by 3 (3 in 3/4) is 8.
8 x 3 = 24, so if we need to fill in the extra 1 in 3/4 (making it 4/4), we would need to add another 8. 24 + 8 = 32. (u can look up ' what is 3/4 of 32 too ')

if your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then how many grams of dietary fiber did you eat
Step-by-step explanation:
100% = 25g
1% = 100%/100 = 25/100 = 0.25g
80% = 80×1% = 80×0.25 = 20g
If your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then 20 grams of dietary fiber you eat.
What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
Given that daily value of dietary fiber is 25g.
You only ate 80% of your daily value of dietary fiber.
We have to find the amount of dietary fiber in grams you eat .
To find this we have to find the value of 80 percentage of 25.
Convert 80 % to the decimal value by dividing 80 with 100.
80/100×25
Eighty by hundred times of twenty five.
20 grams
Hence, if your daily value of dietary fiber is 25 G and if you only ate 80% of your daily value of dietary fiber then 20 grams of dietary fiber you eat.

PQR Airlines reports that 90.5% of its flights arrive on time. What percent of its flights do not arrive on time?
Answer:
9.5%
Step-by-step explanation:
90.5% is the amount of flights that arrive on time, out of 100 so to find out the rest you have to minus 90.5 by 100.
90.5-100 = 9.5
90.5+9.5= 100

O all real numbers
On>2 or n < 6
O 2< n < 6
Answer:
n > 2 or n < 6
Step-by-step explanation:
3 - | 4 - n | < 1
Let's move 3 to the other side of the equation:
- | 4 - n | < 1 - 3
- | 4 - n | < -2
Both sides of the equation are negative, so we can simplify by multiplying them with -1:
(- | 4 - n | < -2*-1
| 4 - n | < 2
We cannot get rid of the module because it's not for a single number and we dont know what n is equal to but there is a rule that we can use to remove the module:
- if | x | < a and a > 0 then -a < x < a. So if we use it we get the following:
- 2 < 4 - n < 2
These are two equations, separate and solve them separately
4 - n < 2
- n < 2 - 4
- n < -2
n > 2 (< turns into > because we changed sign)
and
- 2 < 4 - n
4 - n > -2
-n > -2 - 4
n < 6 (we change the sign of the numbers so the equation changes too)
So after solving the two equation we get the answers
What is the slope of the line that passes through the points (2, -4) and (5, 2)? Write
your answer in simplest form.
Answer:
Slope: 2
The slope how much y increases when x increases by 1.
Step-by-step explanation:
1. Find the difference between both y-coordinates. (6)
2. Find the difference between both x-coordinates. (3)
Divide the difference between y and x. y/x=2
The slope is 2.
Answer:
The slope of line that passes through the points (2, -4) and (5, 2) is 2.
Step-by-step explanation:
Here's the required formula to find slope line :
[tex]{\longrightarrow{\pmb{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}}[/tex]
As per given question we have provided that :
[tex]\begin{gathered}\footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf y_2 = 2\\& \sf y_1 = - 4\\ & \sf x_2 = 5\\ & \sf x_1 = 2\end{cases} \end{gathered}[/tex]
Substituting the values in the formula to find slope line that passes through the points :
[tex]\begin{gathered}\qquad{\longrightarrow{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{(2) - ( - 4)}{5 - 2}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{2 + 4}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{6}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = 2}}}\\\\\qquad{\star{\underline{\boxed{\sf{\pink{m = 2}}}}}} \end{gathered}[/tex]
Hence, the slope of line that passes through the points (2, -4) and (5, 2) is 2.
