A car travels 240 km on 20 liters of petrol. how many litres of petrol is needed to travel 600 km
Answer:
50 L of petrol is needed to travel 600 km.
Step-by-step explanation:
The car travels 1 km in 20/240 L of petrol.
Then,
Petrol needed to travel 600 km
20/240 × 600
20/24 × 60
20/4 × 10
5 × 10
= 50 L
Answer:
50 liters
Step-by-step explanation:
Petrol needed to travel 240 Km = 20 liters
Petrol needed to travel 1 Km = 20/240
Petrol needed to travel 600 Km = [tex]\frac{20}{240} * 600[/tex]
= 50 liters

is y=8+x proportional?
Answer: No, it is linear
Explanation: The constant is +8, meaning the y intercept is 8. Proportional lines go through (0,0), but this line goes through (0,8).

Hi, really need help on this last question for the night, heeeeelp pls.
Answer:
Move it 2 places to the right.
Step-by-step explanation:
The magnitude of the exponent of 10 tell you how many places to move
The sign of the exponent of 10 tells you the direction.
Positive, decimal moves right.
Negative, decimal moves left.
Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.
Answer:
The function has a negative leading coefficient and a maximum vertex point
Explanation:
This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.
This function's end behavior is Down and Down, so it must have a negative leading coefficient.
The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.
This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.
This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.
Answer:
Leading coefficient: negative
Maximum vertex point

Find the domain and solve: √(6+x−x2)=9
Step-by-step explanation:
√(6+x−x²)=9
the domain :
6+x-x² ≥ 0
(3-x)(2+x) ≥0
-2 ≤ x ≤ 3
problem solving:
√(6+x−x²)=9
6+x−x²=81
-x²+x+6-81 = 0
-x²+x-75 = 0
x²-x+75 = 0

Using probability concepts, it is found that P(X) = 0.68.
The probabilities given are:
0.22 probability of a person living in Africa.0.08 probability of a person living in North America.0.06 probability of a person living in South America.0.55 probability of a person living in Asia.0.07 probability of a person living in Europe.0.01 probability of a person living in Oceania.Event X is the probability of living in either South America, Asia or Europe, thus it's probability is the sum of these three probabilities, that is:
[tex]P(X) = 0.06 + 0.55 + 0.07 = 0.68[/tex]
Hence, P(X) = 0.68.

Answer:
0.68
explanation:
you're adding the numbers on the graph together
South America = 0.06
Europe = 0.07
Asia = 0.55
0.06 + 0.07 + 0.55 = 0.68
Sketch the graphs. - 2x + 3y = -1
Answer:
Step-by-step explanation:
y =2/3x + 1/3
slope 2/3
y-intercept: (0 ,1/ 3)
Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1
QUESTION 6
Use the formula for simple interest to find the interest rate if a deposit of $1400 earned $ 490 of interest after 5 years
9514 1404 393
Answer:
7%
Step-by-step explanation:
The simple interest formula is ...
I = Prt . . . . where P is the principal, r is the rate, and t is the number of years
Filling in the given values, we can solve for r.
490 = 1400·r·5
490/7000 = r = 0.07 = 7%
The interest rate was 7%.

the area of a rectangular place mat is 98 inches its length is seven inches longer than the width. find the length and width of the place mat
A
Answer:
width is 7, length is 14
Step-by-step explanation:
x(x+7) = 98
x^2 + 7x = 98
x^2 + 7x - 98 = 0
( x + 14 )( x - 7 ) = 0
x+14=0 results in negative measures
x-7=0 ---> x= 7
width is 7, length is 14

find the whole number quotient and remainder for 52 divided by 8
Answer:
6.5
Step-by-step explanation:
Answer:
6.5
Step-by-step explanation:
Using a calculator, if you typed in 52 divided by 8, you'd get 6.5. You could also express 52/8 as a mixed fraction: 6 4/8. If you look at the mixed fraction 6 4/8, you'll see that the numerator is the same as the remainder (4), the denominator is our original divisor (8), and the whole number is our final answer (6).
