Aya and Mary are 12 miles apart on a path when they start moving toward each other.
Aya runs at a constant speed of 5 miles per hour, and Mary walks at a constant speed
of 3 miles per hour. How long does it take until Aya and Mary meet?
Pleaseee help
Answer:
1.5 hours
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Aya and Mary distance = 12 miles
Let, meeting point from Aya = Z miles
So, Aya covers Z miles to reach Mary.
Hence, Mary covers (12 - Z ) miles to reach Aya
Here, Time = [tex]\frac{Distance}{Speed}[/tex]
Aya = [tex]\frac{Z}{5}[/tex]
Mary = [tex]\frac{12-Z}{3}[/tex]
If, same time taken, then we can solve by following method,
[tex]\frac{Z}{5} = \frac{12-Z}{3}[/tex]
By solving the equation, we get
Z = 60 ÷ 8
Or Z = 7.5 miles
Hence, time taken for both to meet = 7.5 ÷ 5
= 1.5 hours

Can someone tell me how to find the Radius, Diameter, And Circumference Of a Circle?
radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
Diameter:2 times the radius is the circle's diameter.
Circumference:The formula is simply this: C = πd. In this equation, "C" represents the circumference of the circle, and "d" represents its diameter. That is to say, you can find the circumference of a circle just by multiplying the diameter by pi.the formula for circumference of a circle is 2 x pi x r(radius).

pythagorus’ theorum : a^2 + b^2 = c^2
so 9^2 + x^2 = 15^2, x being the missing length
work out x ...

x^2 = 144
x = 12
area of a triangle : 0.5 x base x height
so 0.5 x 9 x 12 = 54

2 ( r - 1 ) + 3 = 19
Answer:
r = 9
Step-by-step explanation:
2 ( r - 1 ) + 3 = 19
2r - 2 = 19 - 3
2r - 2 = 16
2r = 16 + 2
2r = 18
r = 9

The grain is pumped out of a full-grain silo into a barge at a rate of 9 cubic meters per minute. The silo holds 2000 cubic meters of grain. Let y be the cubic meters remaining in the silo after x minutes. Write an equation in slope-intercept form that models the amount of grain in the silo.
How would I solve this?
=========================================================
Explanation:
x = number of minutes
y = amount of grain left over, in cubic meters
We can abbreviate "cubic meters" into "m^3" without quotes of course.
The silo holds 2000 m^3 of grain. This is the initial value, so it is the y intercept. This means b = 2000. If the silo wasn't completely full, then we'd have to use a different initial value.
The slope is -9 because the amount of grain decreases by 9 cubic meters per minute. We can think of it like
slope = rise/run = (change in y)/(change in x)
slope = (change in grain)/(change in time)
Saying slope = -9/1 means the change in grain is -9 m^3 and the change in time is 1 minute.
Because the slope is -9, we say that m = -9
Therefore, we go from y = mx+b to y = -9x+2000
-------------------
Note how plugging x = 0 into the equation leads to
y = -9x+2000
y = -9*0+2000
y = 0 + 2000
y = 2000
Showing that after 0 minutes, aka at the start, we have 2000 m^3 of grain.
Then at the x = 1 minute mark, we have...
y = -9x+2000
y = -9*1+2000
y = -9+2000
y = 1991
Showing that the silo lost 9 m^3 of grain since 2000-1991 = 9.
The graph y = -9x+2000 is a straight line that goes through the two points (0,2000) and (1,1991).

2x+3y=32
5x-4y= -81
Solving for x on the question - 2x + 3y = 32 | Answer : x = [tex]\frac{-3}{2}[/tex]⁻y + 16Solving for y on the question - 2x + 3y = 32 | Answer : y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex] Solving for x on question - 5x - 4y = -81 |Answer : x = [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]
Solving for y on question - 5x - 4y = -81 |Answer : y = [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]Step-by-step explanation:
(Solving for x on question - 2x + 3y = 32)
2x + 3y = 32
Step 1: Add -3y to both sides.
2x + 3y + −3y = 32 + −3y
2x = −3y + 32
Step 2: Divide both sides by 2.
[tex]\frac{2x}{2}[/tex] = [tex]\frac{-3y+32}{2}[/tex]
x = [tex]\frac{-3}{2}[/tex]⁻y + 16
(Solving for y on question - 2x + 3y = 32)
2x + 3y = 32
Step 1: Add -2x to both sides.
2x + 3y + −2x = 32+ −2x
3y = −2x + 32
Step 2: Divide both sides by 3.
[tex]\frac{3y}{3}[/tex] = [tex]\frac{-2x+32}{3}[/tex]
y = [tex]\frac{-2}{3}[/tex]x + [tex]\frac{32}{3}[/tex]
(Solving for x on question - 5x - 4y = -81)
5x − 4y = −81
Step 1: Add 4y to both sides.
5x − 4y + 4y = −81 + 4y
5x = 4y − 81
Step 2: Divide both sides by 5.
[tex]\frac{5x}{5}[/tex] = [tex]\frac{4y-81}{5}[/tex]
x = [tex]\frac{4}{5}[/tex]y + [tex]\frac{-81}{5}[/tex]
(Solving for y on question - 5x - 4y = -81 )
5x − 4y = −81
Step 1: Add -5x to both sides.
5x − 4y + −5x = −81 + −5x
−4y = −5x − 81
Step 2: Divide both sides by -4.
[tex]\frac{-4y}{-4}[/tex] = [tex]\frac{-5x-81}{-4}[/tex]
y = [tex]\frac{-5}{4}[/tex]x + [tex]\frac{81}{4}[/tex]
