Calculate the rate per litre at which a car uses petrol,if it uses 20l of petrol to travel 180 km
Answer:
1 L of petrol is used to travel 9 km.
Step-by-step explanation:
You can find the answers through the ratio method
20 L : 180 km
1 L : x
( x is the number we must find )
20 x = 180
x =
x = 9 km

Find the area of the semicircle. Round your answer to the nearest hundredth. YEAH IVE BEEN STUCK ON THIS help please I need the steps if possible:(
Answer:
your answer will be 127.17 sq in
Step-by-step explanation:
hope it helps you
have a wonderful day!!!
Answer:
=127.23
Step-by-step explanation:
we can start of by finding the area of a CIRCLE
18/2=9
9=radius
area of circle= pi*r squared
9 squared=81*pi=254.4690
Now we can half the area of the circle to find out the area of the semi circle as a semi circle is just half a circle therefore half the area of a circle
254.469/2=127.2345
127.2345=127.23
=127.23

Consider the following incomplete mapping diagrams.
Part A: Complete Diagram A so that it is a function.
Part B: Is it possible to complete Diagram B so that it is NOT a function? If so, complete the diagram to show a relation, but not a function. If not, justify your reasoning.
Part C: Is it possible to complete the mapping diagram for Diagram C so it represents a function? If so, complete the diagram to show a function. If not, justify your reasoning.

Step-by-step explanation:
the volume of sphere is increaseing
at the Constant rate of 10cm²lsee-
Calculate the rate of increase of
the surface area
at the Instant
When the radus is 5cm. What
is the radius of the sphere when
the surface are is increasing at 2cm
Volume of a sphere:
V = 4/3 π r ³
Differentiate V with respect to time t :
dV/dt = 4π r ² dr/dt
Surface area of a sphere:
A = 4π r ²
Differentiate A with respect to t :
dA/dt = 8π r dr/dt
You're given that the volume is increasing at a constant rate, dV/dt = 10 cm³/s, so
10 cm³/s = 4π r ² dr/dt
Solve for dr/dt (the rate of change of the sphere's radius):
dr/dt = 5/(2π r ²) cm³/s
Substitute this into the equation for dA/dt :
dA/dt = 8π r (5/(2π r ²) cm³/s)
dA/dt = 20/r cm³/s
At the moment the radius is r = 5 cm, the surface area is increasing at a rate of
dA/dt = 20/(5 cm) cm³/s = 4 cm²/s
When the surface area is increasing at a rate of dA/dt = 2 cm²/s, the radius r is such that
2 cm²/s = 20/r cm³/s
which happens when the radius is
r = 20/2 (cm³/s) / (cm²/s) = 10 cm

Answer:
PR = 16
SR = 12
Step-by-step explanation:
6/8 = (x-3)/(x+1)
8x-24 = 6x+6
simplify
2x = 30
x = 15
PR = 15 + 1 = 16
SR = 15 - 3 = 12

n = -2
Put the following equation of a line into slope-intercept form, simplifying all fractions.
3x+2y=14
Answer:
y = -3/2x + 7
Step-by-step explanation:
First, let's identify what slope-intercept form is: y = mx + b
We have:
3x + 2y = 14
Right away, we can see that we need to 1) move x to the right side of the equation and 2) simplify y.
1) To move x to the right side of the equation, subtract 3x from both sides.
2y = -3x + 14
2) To simplify y, divide both sides by 2. When dividing the right side by 2, you need to evaluate each component (3x and 14, not just one)
y = -3/2x + 7
This is your equation in slope-intercept form.

Find the x value in the triangle shown below
NEED HELP
Answer:
BY Seeing the figure we can say that it is an
isosceles triangle so 70° +x+x=180° (Angle sum property)70 +2x=180
2x=180-70
2x = 110
x= 110÷2
