62 people like coffee or tea, or both
A survey of 70 people found that 50 like coffee, 25 like tea, and 13 like both.
The amount of people that like only coffee = 50 - 13 = 37
The amount of people that like only tea = 25 - 13 = 12
The amount of people that like neither = 70 - (37 + 12 + 13) = 8
The amount of people who like coffee or tea, or both = 37 + 12 + 13 = 62

Answer:
13 like both
12 like tea
37 like coffee
62 people like coffee, tea or both
8 don't like neither of them
Step-by-step explanation:
let us remember that 25 people like tea but 13 of them like both. And 50 people like coffee but 13 like both.
so:
25-13=12
12 equals to the number of people that only like tea.
50-13=37
37 equals to the number of people that only like coffee.
If you add the 13 (that like both) + 12 (that like tea) + 37 (that like coffee) that equals to 62 people that like coffee or tea, or both.
13+12+37=62
62 equals to the number of people that like coffee or tea, or both
So that means that 8 people don't like either coffee or tea.

At Handy Hardware Shop's annual spring-cleaning sale, every ratchet set in the shop gets marked down. Austin purchased 2 ratchet sets during the sale: one for himself and one to give to his dad on Father's Day. Each ratchet set cost $8 less than its full price. He paid a total of $56. What is the cost of each ratchet set at full price?
Answer:
answer is 36
Step-by-step explanation:
The cost of each ratchet set at full price was $36.
Given that in a sale a ratchet set cost $8 less than its full price. Austin paid a total of $56.
We to find the cost of each ratchet set at full price,
Let's denote the cost of each ratchet set at full price as "x" dollars.
According to the information given, each ratchet set was marked down by $8, so their sale price would be (x - $8) dollars each.
Austin purchased 2 ratchet sets, so the total cost of his purchase would be:
2 (x - $8) = $56
Now we can solve for "x":
2 (x - $8) = $56
2x - $16 = $56
2x = $56 + $16
2x = $72
x = $72 / 2
x = $36
So, the cost of each ratchet set at full price was $36.

4. If f(x) = x2, g(x) = 5x, and h(x) = x +4, find each value.
Find h[f(4)].
Step-by-step explanation:
f(x) = x²
g(x) = 5x
h(x) = x + 4
= h[f(4)]
= x + 4
= f(4) + 4
= (4)² + 2
= 16 + 2
= 18
h[f(4)] = 18

Answer:
(b) 7/80
Step-by-step explanation:
As a decimal

The symbol % is fully equivalent to the division /100. That is why we can replace (8 3/4)% with (8 3/4)/100.
A linear function contains the points (-3, -7) and (6,-4). Which of the following points does it also include?
A.(-9,3)
B.(3,-6)
C.(12,2)
D.(9,-3)
The given points defines a line from which the linear function can be
determined and the included point on the line can be found.
The point also included on the line is D. [tex]\underline {(9, \, -3)}[/tex]
Reasons:
The given points on the linear function are; (-3, -7), (6, -4)
The slope of the line is given as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
Therefore, we get;
[tex]Slope, \, m =\dfrac{-4-(-7)}{6-(-3)} = \dfrac{1}{3}[/tex]
The equation of the function is therefore;
[tex]y - (-4) = \dfrac{1}{3} \cdot (x - 6)[/tex]
[tex]y = \dfrac{x}{3} - 6[/tex]
Graphing the above equation on the calculator gives the points;
(-9, -9), (3, -5), (12, -2), and (9, -3)

WRITE AN EQUATION IN SLOPE INTERCEPT FORM FOR THE PERPENDICULAR TO Y=2X-3 Y=2X-3 PASSES THOUGH THE POINT (-3,-3)
Step-by-step explanation:
The slope of the line [tex]y = 2x - 3[/tex] is 2, which means that a line perpendicular to this will have a slope equal to its negative reciprocal or [tex]m = -\frac{1}{2}.[/tex] So we can write the slope-intercept form of the line's equation as
[tex]y = -\frac{1}{2}x + b[/tex]
To find the value of b, we use the value of the given point (-3, 3):
[tex]\Rightarrow 3 = -\frac{1}{2}(-3) + b[/tex]
Solving for b, we get
[tex]b = \frac{3}{2}[/tex]
Therefore, the slope-intercept form of the equation for the perpendicular line is
[tex]y = -\frac{1}{2}x + \frac{3}{2}[/tex]
