A scuba instructor charges a $150 equipment fee, plus $65 per hour for classes. Write an expression to represent the total cost, C, of lessons as a function of the numefer of hours, h, of the lesson.
Answer: (consider leaving a thanks)
Since the equation representing the total cost is C, we would write:
C = (rest of equation will go here)
Then, since the price goes up with the number of hours (h) by 65$ each hour, we would write it as (65h)
C = 65h (Final part!)
Finally, since 150$ is added on, and isn't connected to the number of hours we would write the equation like this:
C = 65h + 150

What is the image of (5,-8)(5,−8) after a reflection over the x-axis?
Answer:
(5,8)
Step-by-step explanation:
(x,y) --> (x,-y)
The image of the point (5, -8) after a reflection over the x-axis is (5, 8).
When reflecting a point over the x-axis, the x-coordinate remains the same while the y-coordinate changes sign. Given the point (5, -8), after a reflection over the x-axis, the new coordinates will be (5, 8).
Here's the step-by-step process:
Keep the x-coordinate the same (x remains 5).
Change the sign of the y-coordinate (-y becomes 8).
Combine the new coordinates to get the reflected point (5, 8).
Therefore, the image of the point (5, -8) after a reflection over the x-axis is (5, 8).
A rectangle has an area of 80cm squared and a perimeter of 48cm find the length and width of the rectangle
2 possible solutions.
When width is 4 cm, length is 20 cm; When width is 20 cm, length is 4 cm
Step-by-step explanation:
Step 1: Let the width of the rectangle be x. Perimeter of the rectangle = 48 cm. Find expression for length.Perimeter of the rectangle = 2(length + width)
48 = 2(length + x)
24 = length + x
⇒ Length = 24 - x
Step 2: Find the dimensions if area = 80 cmArea of the rectangle = length × width
80 = x (24 - x)
80 = 24x - x²
x² - 24x + 80 = 0
x² - 20x - 4x + 80 = 0
x(x - 20) - 4(x - 20) = 0
(x - 4)(x - 20) = 0
⇒ x = 4, 20
24 - x = 20, 4
So there are two possible answers.
When width is 4 cm, length is 20 cm
When width is 20 cm, length is 4 cm

Question 6
In a box of 11 parts, 4 of the parts are defective. Two parts are selected at random without replacement.
Find the probability that both parts are defective.
The probability that both parts are defective is 6/55
Step-by-step explanation:
Defective parts = 4
Total parts = 11
Probability of getting a defective part = 4/11
Probability of getting defective part 2nd time = 3/10
Total probability of getting defective part both the times = (4/11) (3/10)
= (12/110)
= (6/55)
The probability that both parts are defective is 6/55
If the number of bacteria on the surface of your phone triples every hour and can be described with the exponential function f(x)=1,000⋅3x, complete the blank in the table of values to show how much bacteria is on your phone after 4 hours.
x f(x)
1 3,000
2 9,000
3 27,000
4 _[blank]_
Answer:
81,000
Step-by-step explanation:
1 1,000x3= 3,000
2 3,000x3= 9,000
3 9,000x3= 27,000
4 27,000x3= 81,000
The number of bacteria on your phone after 4 hours is 81,000.
Explanation:To calculate the number of bacteria on your phone after 4 hours using the exponential function f(x) = 1,000 * 3^x, we can substitute x with 4. So the equation becomes f(4) = 1,000 * 3^4.
Calculating this, we get f(4) = 1,000 * 81 = 81,000.

Step-by-step explanation:
What is the surface area of the triangular prism shown below
???
Given:
Given that the base of the triangle is 4 cm.
The height of the triangle is 3 cm.
The height of the prism is 8 cm.
The other side of the triangle is 5 cm.
We need to determine the surface area of the triangular prism.
Surface area of the triangular prism:
The surface area of the triangular prism can be determined using the formula,
[tex]SA=bh+(s_1+s_2+s_3)H[/tex]
where b is the base of the triangle,
h is the height of the triangle,
s₁, s₂, s₃ are the side lengths of the triangle and
H is the height of the prism.
Substituting b = 4, h = 3, s₁ = 4, s₂ = 3, s₃ = 5 and H = 8, we get;
[tex]SA=(4)(3)+(4+3+5)(8)[/tex]
[tex]SA=12+(12)(8)[/tex]
[tex]SA=12+96[/tex]
[tex]SA=108 \ cm^2[/tex]
Thus, the surface area of the triangular prism is 108 square cm.

These box plots show daily low temperatures for a sample of days in two
different towns. Which statement is the most appropriate comparison of the spreads?
Given:
The box plots show daily low temperatures for a sample of days in two different towns.
We need to determine the most appropriate comparison of the spreads.
Interquartile range of town A:
The interquartile range can be determined by subtracting the end values of the boxes.
Thus, we have;
Interquartile range = 40 - 20
Interquartile range = 20
Thus, the interquartile range for town A is 20.
Interquartile range for town B:
The interquartile range for town B is given by
Interquartile range = 45 - 35
Interquartile range = 10
Thus, the interquartile range for town B is 10.
Hence, the interquartile range (IQR) for town A, 20° is greater than the IQR for town B, 10°
Hence, Option A is the correct answer.

A line has a slope of One-fourth and passes through point (0.4, negative one-half). What is the value of the y-intercept?
Answer:
-0.6
Step-by-step explanation:
What is the y-intercept of y = 50 - 1?
Answer:
49 or -1
Step-by-step explanation:
(im going to assume you meant y=50-1 and not y=50x-1)
The intercept would literally be 49 since 50-1=49
y=50x-1 would mean the y intercept is -1
Answer:
the y intercept is (0,49) Plz give branliest i need to level up
Step-by-step explanation:
50 - 1 = 49
y always equals 49
so the y axis is at x coordinate 0 and y intercept is at the y axis
so the point is (0,49)

10. Charlie biked 15 minutes home from school and then walked 12 minutes to the pizza place near his house. This trip was 3.6 miles in total. His rate on his bike is 3 miles per hour less than 5 times his walking rate. In miles per hour, what is Charlie’s speed as he walks and what is his speed as he bikes?
Answer:
3mph and 12mph
Step-by-step explanation:
GIVEN: Charlie biked [tex]15[/tex] minutes home from school and then walked [tex]12[/tex] minutes to the pizza place near his house. This trip was [tex]3.6[/tex] miles in total. His rate on his bike is [tex]3[/tex] miles per hour less than [tex]5[/tex] times his walking rate. In miles per hour.
TO FIND: Charlie’s speed as he walks and his speed as he bikes.
SOLUTION:
Let speed of charlie when he walks be [tex]x\text{ mph}[/tex]
Then speed of charlie as he biked [tex]=5x-3\text{ mph}[/tex]
Total length of trip [tex]=3.6\text{ miles}[/tex]
Total time taken[tex]=27\text{ minutes}=\frac{27}{60}\text{ hour}=\frac{9}{20}\text{hour}[/tex]
Now,
[tex]\text{Distance}=\text{speed}\times\text{time}[/tex]
distance traveled on bike [tex]=(5x-3)\times\frac{15}{60}=\frac{(5x-3)}{4}[/tex]
distance traveled by walking [tex]=x\times\frac{12}{60}=\frac{x}{5}[/tex]
As, [tex]\frac{(5x-3)}{4}+\frac{x}{5}=3.6[/tex]
[tex]\frac{29x-15}{20}=3.6\implies 29x=87[/tex]
[tex]\implies x=3\text{ mph}[/tex]
Speed of Charlie on bike [tex]=5x-3=12\text{ mph}[/tex]
Hence speed of charlie on bike and by walking is 12mph and 3mph respectively
What is the volume?
9 m
19 m
7 m
Answer:1197m³
Step-by-step explanation:
Answer:
Volume of a triangular irregular prism=1300.16m^3 = 1300m^2
Volume of a rectangular prism two answers = 1197m^3 or 1233m^3
Step-by-step explanation:
With rectangular prism two answers we need the rectangle surface area first
A = 9 m x 19 m = 171m
or A = 7 m x 19m
The rectangle prism could be 1197m^3 or 1233m^3
depending how big the rectangle is as we calculate that first then multiply by depth. If we had the direction of measurement of the base we would just get one answer and not two.
Rectangular prism A = 171sq
V = 1197m^3 = (171sq x 7)
or V= 1233m^3 = 137sq x 9
If the prism is a irregular prism we add the surface area's
V = (a+b+c)B/3
V = (7x19)(9x7) (9x19) x B = 133 + 63 + 197 x 197 = 3900.5/3 =1300.16

A gardener is planting two types of trees:
Type A is 10 feet tall and grows at a rate of 21 inches per year.
Type B is 7 feet tall and grows at a rate of 25 inches per year.
Algebraically determine exactly how many years it will take for these trees to be the
same height.
9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.
Step-by-step explanation:
The given is,
Type A is 10 feet tall and grows at a rate of 21 inches per year
Type B is 7 feet tall and grows at a rate of 25 inches per year
Step:1
Convert the rate of grows of tree inch to feet,
For Tree A,
Rate of grow, A = 21 inches per year
= 21 × 0.0833333 ( 1 inch = 0.0833333 feet)
= 1.75 feet per year
For Tree B,
Rate of grow, B = 25 inches per year
= 25 × 0.0833333 ( 1 inch = 0.0833333 feet)
= 2.08333 feet per year
Step:2
Difference in the tall of Tree A & B,
= 10 - 7
= 3 feet
Difference in the rate of grow of tree A & B,
= 2.08333 - 1.75
= 0.3333325 feet per year
Step:3
Year take to both trees are same height,
[tex]= \frac{Difference in the height of tree A & B}{Difference in the rate of grows of A & B}[/tex]
[tex]= \frac{3}{0.3333325}[/tex]
[tex]= 9.00[/tex]
= 9 years
Step:4
Check for solution,
Height of tree = Height of Tree + (Rate of grow × Years)
For A,
= 10 + ( 1.75 × 9 )
= 25.75 feet.........................................(1)
For B,
= 7 + ( 2.08333 × 9 )
= 25.74999
≅ 25.75 feet.....................................(2)
From Equation (1) and (2),
25.75 feet = 25.75 feet
Result:
9 years will take foe these trees to be the same height, If type A is 10 feet tall and grows at a rate of 21 inches per year and type B is 7 feet tall and grows at a rate of 25 inches per year.
