Joshua drove his car a distance of 449.6 miles, and it required 12.9 gallons of gasoline (petrol). How many liters of fuel will it take to go 100 kilometers?
Answer:
6.75L of fuel are needed
Step-by-step explanation:
To solve this question we need to convert the miles to km and the gallons to liters in order to find the km/L that the car is doing:
km -1km = 0.621371miles-
449.6miles * (1km / 0.621371 miles) = 723.56km
L -1L = 0.264172gal-
12.9gal * (1L / 0.264172gal) = 48.83L
km/L:
723.56km / 48.83L= 14.82km/L
The liters the car takes to go 100km are:
100km * (1L / 14.82km) = 6.75L of fuel are needed

8 sin 60 = x
6.92820323=x
Pls help there’s the info above
Answer:
When you're given a line, you can find the rise over the run also known as the slope using a graph, calculating it using the formula, or using a table with two points you've been given from the line. Once you find the slope find the y-intercept which is the point at which the line intercepts with the y-axis of the cartesian plane. I also added some attachments of my own work and an explanation of slope.

Which equation represents a line that passes through (2, -1/2) and has a slope of
3?
Answer:
it should be d or c
Step-by-step explanation:
The graph of a linear function passes through the
points (2, 11) and (6,21).
Write an equation for the function.
Use the number pad to enter numbers in the boxes.
y me
| x2 +
Answer:
y = 5/2x + 6
Step-by-step explanation:
Find the slope:
[tex]m=\frac{y_1-y_2}{x_1-x_2}\\\\m=\frac{11-21}{2-6}\\\\m=\frac{-10}{-4}\\\\m=\frac{5}{2}[/tex]
Use point-slope form to find the equation in slope-intercept form:
[tex]y-y_1=m(x-x_1)\\\\y-11=\frac{5}{2} (x-2)\\\\y-11=\frac{5}{2}x-5\\\\y=\frac{5}{2}x+6[/tex]
The equation of the line for the function will be y = 5/2x + 6.
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
The general form of the equation of the line:-
y = mx + c
m = slope
c = y-intercept
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given that the graph of a linear function passes through points (2, 11) and (6,21).
Slope = ( 21 - 11 ) / ( 6 - 2 )
Slope = 10 / 4
Slope = 5 / 2
The y-intercept will be calculated as:-
y = mx + c
y = ( 5 / 2 )x + c
11 = ( 5 / 2 ) x 2 + c
c = 11 - 5
c = 6
The equation of the line will be:-
y = mx + c
y = (5/2)x + 6

9. A pyramid has a volume of 148 cm3. If a prism has exactly the same base area and the
same height as the pyramid, what is the volume of the prism? Please show work or write an
explanation to back up your answer!
I.
Answer:
Volume of the prism = 444 cm³
Step-by-step explanation:
Volume of the pyramid is given by the expression,
Volume = [tex]\frac{1}{3}(\text{Area of the base)}(\text{Height})[/tex] = 148 cm³
⇒ (Area of the base)×(Height) = 3×148
= 444
Since, area of the base and height of a prism are the same as pyramid,
Volume of prism = Area of the base × Height
= 444 cm³
Therefore, volume of the prism = 444 cm³

Work out the time taken, in minutes, for a 68km journey at an average speed of 85km/h
Answer:
48 minutes
Step-by-step explanation: Time taken is distance divided by speed, so 68/85 is 0.8. 0.8 is equal to 4/5. 4/5 of an hour is 48 minutes.
Brayden earns $22 per hour. He regularly works 40 hours per week. If he works 16 overtime hours (at time-and-a-half), what would be his gross pay that week?
Answer:
22 +11 = $33 an hour overtime
$22x40 =$880
$33×16=$528
$528+$880= $1408
find the ratio in which the point (3,y) divides the line joining the point (9,8) and (-4,-6) hence find the value of y
Answer:
m1:m2 = 6:7
y = 7 (Approx.)
Step-by-step explanation:
Given:
Dividing point (3, y)
Two points (9 , 8) , (-4 , 6)
Find:
Ratio
Value of y
Computation:
X = [(m1)(x2) + (m2)(x1)] / [m1 + m2]
3 = [(m1)(-4) + (m2)(9)] / [m1 + m2]
3m1 + 3m2 = -4m1 + 9m2
7m1 = 6m2
m1 / m2 = 6 / 7
m1:m2 = 6:7
Y = [(m1)(y2) + (m2)(y1)] / [m1 + m2]
y = [(6)(6) + (7)(8)] / [6 + 7]
y = [36 + 56] / 13
y = 92 / 13
y = 7.07
y = 7 (Approx.)

In the figure shown PS = RQ. which theorem can be used to prove Triangle SQR = Triangle QSP?
I'm not sure which answer it is can you help me?
Answer:
HL (hypotenuse leg)
Step-by-step explanation:
From the diagram, we have two sides that are congruent
The side QS is common to both triangles
Also, we have it that the side PS and QR are congruent
What this mean is that we have two sides that are already the same
Now, looking at the right angle position in both, we can see that QR and PS represents the hypotenuse of individual right angles
Using the HL congruence statement, since we have it that the hypotenuse one side is already congruent, we can conclude that the last side too is congruent and as such both triangles are congruent to each one another
