A car and a motorcycle leave the city at the same time and drive to a lake that is 120 km away. The speed of the motorcycle is 20 km per hour greater than the speed of the car, so the motorcycle arrives at the lake 1 hour before the car. Find the speed of the car and the speed of the motorcycle. Plz answer fast!!
Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Ed buys a box of eggs costing £2.80, two packs of bacon for £2.40 each and two tins of baked beans. He pays with a £10 note and gets 80p change. How much does a tin of beans cost in pounds, £?
Answer:
£0.8
Step-by-step explanation:
egg = 2.80
Bacon = 2 * 2.40 = 4.80
Baked beans = 2 tins
Amount issued = 10
Change obtained = 80p = 0.8
Let cost per baked beans = x
Hence,
2.80 + 4.80 + 2x = 10 - 0.8
7.60 + 2x = 9.20
2x = 9.20 - 7.60
2x = 1.6
x = 1.6 / 2
x = 0.8
Hence, a tin of baked beans cost £0.8
Answer:
£0.80
Step-by-step explanation:
egg = 2.80
Bacon = 2 * 2.40 = 4.80
Baked beans = 2 tins
Amount issued = 10
Change obtained = 80p = 0.8
Let cost per baked beans = x
lol
2.80 + 4.80 + 2x = 10 - 0.8
7.60 + 2x = 9.20
2x = 9.20 - 7.60
2x = 1.6
x = 1.60 / 2
x = 0.80
YES WE GOT IT, a tin of baked beans cost £0.80

Number 13 Find the measures of angles 1, 2, and 3.
Answer:
1. 37
2. 26
3. 26
Step-by-step explanation:
Subtracting 63 from 180, you find the linear pair, being 117 which helps find an angle in the lower triangle. The sum of all angles is 180, and to find 2, you subtract the known angles ( 180-(37+117)) which equals 26. Knowing the shape is a parallelogram, and the opposite sides are parallel, we can say 2 and 3 are congruent through the alternate interior angles theorem. 1 is found through applying the same theorem.

17. y=1 - 2x x=9
(Help this is due today)
Answer: y= -17
Step-by-step explanation:
y= 1 - 2x
so when x=9,
y= 1 - 2(9)=1 - 18= -17
Answer:
y=-17
Step-by-step explanation:
y= 1-2x
since x=9, we substitute the x for 9
y= 1-2(9)
then we multiply 2 with 9
y= 1-18
y=-17
Someone pleaseee help meeeee :( ???? On this.
Answer:
A. 9
Step-by-step explanation:
To solve slope with points, use the equation: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]. In this case it would be: [tex]\frac{7 - (-2) }{-6- (-7) }[/tex]. 7 - -2 is also 7 + 2 or 9. -6 - - 7 is also -6 + 7 or 1. So the final fraction is [tex]\frac{9}{1}[/tex] or 9.
Hope it helps!

Answer:
For the first question the answer is 50(0.2 + 1)^2 = 72
For the second question it is y = 32
Step-by-step explanation:
In case you need to see how i got it...it's below
For number 1, y is proportional to (x + 1)^2
The equation would be y(x +1)^2 = k(the constant). Then I substituted numbers you gave me in the equation which was : 50(0.2 + 1)^2 = k(72)
For number 2 I used this equation: y (x + 1)^2 = 72. I substituted x for 0.5. The equation will be: y(0.5 + 1)^2 = 72. Then I got 32 for y.
Hope this helps:)

462÷7=66
Your answer is 461
Answer:
461
Step-by-step explanation:
Work backwards.
7 X 66=462
462-1=461
So 461 is the answer
3. The time taken for a water heater to boil water is inversely proportional to the
power of the water heater. When the power is 2000 Watts it takes 240 seconds to
boil the water. Find the time it takes to boil water when the power is reduced to
1000 Watts.
I
Answer:
t = 480 seconds
Step-by-step explanation:
Let
Time taken for a water heater to boil water = t
power of the water heater = p
Constant of proportionality = k
t = k/p
240 = k/2000
Cross product
240 * 2000 = k
k = 480,000
Find the time it takes to boil water when the power is reduced to 1000 Watts.
t = k/p
= 480,000/1000
= 480
t = 480 seconds
t = 480 seconds when p = 1000 watts

Each serving for a box of trail mix is 3/8 of a cup.
Enter the number of 3/8 -cup servings there are in 1 1/2 cups of trail mix.
Answer:
It's 4
Step-by-step explanation:
It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.
1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)
