Answer: 15 gallons
Step-by-step explanation:
Here you are going to want to set up a proportion. 918 miles per 27 gallons = 510 miles per x gallons
918/27 = 510/x
Cross multiply and you get 918x = 13770
and you get x = 15
Or you could do 918 miles / 27 gallons = 34 miles / gallon
and divide the 510 miles of distance by how many miles per gallon, so
510 / 34
15

Function f is defined by f(x)=3/2x+c. If f(6)=1, what is the value of f(c)?
Please don't just give me an answer, explain it so I understand. Thanks.
Answer:
C = - 8
Step-by-step explanation:
[tex]f(x) = \frac{3}{2} x + c \\ \\ plug \: x = 6 \\ \\ f(6) = \frac{3}{2} \times 6 + c \\ \\ f(6) = 3 \times 3 + c \\ \\ f(6) = 9+ c \\ \\ \therefore \: 1 = 9 + c \: \{ \because \: f(6) = 1 \} \\ \\ 1 - 9 = c \\ \\ \huge \red{ \boxed{ c = - 8}}\\\\

2. A Cylindrical hot water tank is closed at both ends. The radius of the tank is 0.5m and the height is 0.75.calculate i. The volume of the Cylinder it. The total surface area of the tank (take π =22 out of 7
Answer:
Volume = 0.59 m³
Surface Area = 3.93 m²
Step-by-step explanation:
Given :-
- Radius = 0.5 cm
- Height = 0.75 cm
To Find :-
- Volume
- Surface Area
Solving :-
Volume = πr²h
= 22/7 x (0.5)² x 0.75
= 22/7 x 1/4 x 3/4
= 66/112
= 33/56 m³
= 0.59 m³
Surface Area = 2πr (r + h)
= 2 x 22/7 x 0.5 (0.5 + 0.75)
= 22/7 x 5/4
= 110/28
= 55/14 m²
= 3.93 m²
Solution :-
Volume = 0.59 m³
Surface Area = 3.93 m²
Answer:
1. Formula for volume of a cylinder;
V = πr^2h
where pi is 3.14 or 22/7, r is the radius(0.5) which is squared, and h is the height
plug in the actual values;
V = πr^2h
V = 3.14 * 0.5^2 * 0.75
V = 3.14 * 0.25 * 0.75
V = 0.785 x 0.75
V = 0.58875^3 meters or 0.59^3 meters, is the volume. (round to whatever place they covet)
2. Formula for surface area of a cylinder;
SA = 2πr(r + h)
Plug in the actual values:
SA = 2πr(r + h)
SA = 2 x 3.14 x 0.5(0.5 + 0.75)
SA = 2 x 3.14 x 0.5(1.25)
SA = 2 x 3.14 x 0.625
SA = 3.925 meters or 3.93 meters is the surface area.

Make the triangles into a rectangle, find the area and add it to the original square
Answer: 96 in²
Step-by-step explanation: The parallelogram is comprised of two triangles and one square. You could solve this one of two ways.
1) Find the area of the total parallelogram. The area is b*h, where b is the base and h is the height. The base will ALWAYS be the sum of whatever is on the bottom. In this model, we have 4" and 8", meaning b=12". Now, the height is 8" as seen by the vertical line connecting the top and bottom of the figure. 12 times 8 is 96 inches squared.
2) Find the area of the square and two triangles. The area of a triangle is 1/2*b*h, where b is the base (4") and h is the height (8"). Seeing as we have two triangles, we can do this twice, getting 0.5*4*8 + 0.5*4*8 (1/2 is the same as 0.5 btw). 32 inches squared is for the two triangles. Finally, you need to find the square. To review, the area of a square is s^2, so 8*8 is 64. 64+32 is 96 inches squared.
A two-way frequency table shows grades for students in college and students in high school: high school college total gpa above 3.0 14 26 40 gpa below 3.0 46 14 60 60 40 100 based on this data, are "being in high school" and "gpa above 3.0" independent events? yes, p(high school ∩ gpa above 3.0) = p(high school) ⋅ p(gpa above 3.0) no, p(high school ∩ gpa above 3.0) = p(high school) ⋅ p(gpa above 3.0) yes, p(high school ∩ gpa above 3.0) ≠ p(high school) ⋅ p(gpa above 3.0) no, p(high school ∩ gpa above 3.0) ≠ p(high school) ⋅ p(gpa above 3.0)
Based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.
What is conditional probability?The conditional probability is the happening of an event, when the probability of occurring of other event is given.
A two-way frequency table shows grades for students in college and students in high school.
Let H represent being in high school and G represent the GPA above 3.0. To be an independent event, they must be,
[tex]P(H|G)=P(H)[/tex]
The conditional probability of event H, given that the G is occurred, can be calculated as,
[tex]P(H|G)=\dfrac{14}{40}\\P(H|G)=0.35[/tex]
Total students below 3.0 GPA are 60 and the total number of student are 100. Thus, the probability of being in high school is
[tex]P(H)=\dfrac{60}{100}\\P(H)=0.6[/tex]
Here, conditional probability [tex]P(H|G)[/tex] is not equal to the probability of being in high school.
Hence, based on the data in two-way frequency table, "being in high school" and "gpa above 3.0" are not independent events.

If one root of the equation x^2 + 5x + k = 0 is -2, what is the value of k?
Answer:
k = 6
Step-by-step explanation:
given x = - 2 is a root then substitute x = 2 into the equation
(- 2)² + 5(- 2) + k = 0
4 - 10 + k = 0
- 6 + k = 0 ( add 6 to both sides )
k = 6
Answer:
k = 6
Step-by-step explanation:
since x = - 2 put x = 2 into the equation
(- 2)² + 5(- 2) + k = 0
4 - 10 + k = 0
-6 + k = 0
+6 +6
k = 6
Which trigonometric functions have the same maximum value?
This is a list of trigonometric functions with the same maximum value:
(A) y = arcsinx and y = cos x
What are trigonometric functions?
The trigonometric functions in mathematics are real functions that connect the right-angled triangle's angle to the ratios of its two side lengths.
They are extensively employed in all fields of geometry-related study, including geodesy, solid mechanics, celestial mechanics, and many others.
There are six popular trigonometric functions for an angle.
Sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), and cosecant are their respective names and acronyms (csc).
So, the following equations give us the following maximum values:
arcsinx = -1 to 1
arccosx = -1 to 1
arctanx = -pi/2 to pi/2
arcsecx = ∞
Arcsinx and Arccosx are trigonometric functions that have the same maximum value.
Therefore, this is a list of trigonometric functions with the same maximum value:

Answer:
8π inches or approximately 25.12 inches
Step-by-step explanation:
What's the circumference of a circle?
❖ The circumference of a circle is the distance around a circle.
How do we find the circumference of a circle?
❖ The formula to find the circumference of a circle is 2πr, where r =
radius. We can solve in terms of pi, or approximate pi to 3.14

[tex]3.14*4*2[/tex] [tex]3.14*8[/tex] 25.12 inchesHave a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
See below.
Step-by-step explanation:
Hi there!
We are given a circle, and inside that circle, we know that the radius of that circle is 4 inches
We want to find the circumference of the circle.
The circumference (C) is essentially the perimeter of a circle; the formula for the circumference of a circle is 2πr (r is the radius, π is pi)
Since we know the radius, we can substitute that value into the formula
C=2πr, r=4
C=2π*4
C=8π
If you need the answer in terms of pi, then the answer is 8π inches. However, if you need a number, then substitute an approximation for π, which will usually be 3.14 or 22/7
Using 3.14 for example,
C=8*3.14=25.12 inches
Using 22/7 meanwhile,
C=8*22/7=25.14 inches (rounded to the nearest hundredth)
So the answer is either 8π inches, 25.12 inches, or 25.14 inches (depending on how you need it approximated)
Either way, hope this helps!
