Answer:
36 pots
Step-by-step explanation:
If the gardener has 12kg and wants to put 1/3 in each pot, he would have to divide the 12 kilos by 1/3 kg
12 ÷ 1/3 =
12 x 3 = 36 pots
(2,-8) and has a slope of 4
Answer:
The equation of the line is;
y = 4x - 16
Step-by-step explanation:
Here, we want to find the equation of a line that passes through the point (2,-8) and has a slope of 4
To get this equation, we are going to use the point-slope form
Thus, we have it that;
y-y1 = m(x-x1)
y -(-8) = 4(x-2)
y + 8 = 4x - 8
y = 4x -8-8
y = 4x - 16
A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode? Firework A 240 ft/s Firework B 200 ft/s
Answer: 1.50 seconds
Step-by-step explanation:
Let x = Time taken by Firework A to explode( in seconds ).
Time taken by Firework B = x+ 0.25 seconds
Distance covered = Time × Speed
Distance covered by Firework A = 240 x
Distance covered by Firework B = 200 (x+0.25) = 200x+50
When both at same height , then
240x = 200x+50
⇒ 240x- 200x =50
⇒40x =50
⇒ x = 1.25
Total time = x+ 0.25 = 0.25+ 1.25 = 1.50 seconds
Hence. after Firework B launches it will take 1.50 seconds to launch.

Answer:
(b) see below
Step-by-step explanation:
These tables all have x-values that are consecutive integers, including 0.
The equation has an x-coefficient of -1/2, so as x increases by 1, y should decrease by 1/2 from one row of the table to the next. This is only the case for table B.
__
As another check, the y-value for x=0 is the constant in the equation, -1. That is not the case for table C, further evidence that C is incorrect.

Answer:
x is 5
ST is 45
Step-by-step explanation:
In the given figure
∵ m is the bisector of the segment SU
→ That means m intersects SU at the midpoint of SU
∵ m ∩ SU at point T
∴ T is the midpoint of SU
→ The midpoint of a segment divides it into two equal parts
∵ The point T divides SU to ST and TU
∴ ST = TU
∵ ST = 9x
∵ TU = 4x + 25
→ Equate them
∴ 9x = 4x + 25
→ Subtract 4x from both sides
∵ 9x - 4x = 4x - 4x + 25
∴ 5x = 25
→ Divide both sides by 5
∴ x = 5
→ Substitute the value of x in ST
∵ ST = 9(5) = 45
∴ ST is 45

A shipping container will be used to transport several 80-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 25000 kilograms. Other shipments weighing 9200 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 80-kilogram crates that can be loaded onto the shipping container?
Answer:
197
Step-by-step explanation:
Given that :
Weight of crate = 80kg
Greatest weight container can load = 25000 kg
Weight of other shipments on container = 9200kg
Greateat Number of 80kg crates = c
Weight of other shipment + (weight of crate * number of crates) ≤ greatest weight of container
9200 + (80 * c) ≤ 25000
9200 + 80c ≤ 25000
80c ≤ 25000 - 9200
80c ≤ 15800
c ≤ 15800 / 80
c ≤ 197.5
Hence, maximum number of 80kg crate is 197
The inequality which can be used to determine c will be "[tex]9200 + 80c \leq 25000[/tex]". A complete solution is below.
Given values are:
Crates' weight,
80kgGreatest weight container,
25000 kgOther shipments' weight
9200 kgLet,
The Greatest number of 80kg crates will be "c".Now,
As we know the formula,
→ [tex]Other \ shipments' \ weight + (Crates' \ weight\times Number \ of \ crates) \leq Greatest \ weight \ container[/tex]By substituting the values, we get
→ [tex]9200 + (80\times c) \leq 25000[/tex]
→ [tex]9200 + 80c \leq 25000[/tex]
Thus the above response is right.

Which question can be answered using the expression 1/3 Divided By 3/4
Answer:
0.4
Step-by-step explanation:
The question that can be answered using the expression can be 1/3 of the total apple pie is divided in to 3/4 parts.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is 1/3 ÷ 3/4.
Here the operation is division.
So 1/3 of something is divided in to 3/4 parts.
Let a total amount of something be 1/3 units.
Suppose you have to divide it into 3/4 parts.
Then this expression can be used.
Let the total amount of apple pie left is 1/3 part of the total.
You have to divide t into 3/4 parts.
Hence the word problem can be 1/3 of the total apple pie is divided in to 3/4 parts.

Casey is trying to run a certain number of miles by the end of the month if Casey is 60% of the way to achieving our goals and she has already ran 24 miles how many miles is she trying to run by the end of the month
Answer:
40 miles is her goal.
Step-by-step explanation:
The problem says that 24 miles is 60% of her goal for that month.
You cab make a proportion with x being the goal for the whole month.
24/x = 6/10
You cross multiply and get:
6x = 24 x 10
6x = 240
x = 40
40 miles is the answer.

The population of Kenya was 45.1 million in 2009 and has been growing by 2.3% each year. If this trend continues, in what year will the population exceed 52.2 million?
Answer:
6.4294 years
Step-by-step explanation:
45.1 million in 2009 -- 2.3% each year
In what year will the population exceed 52.2 million?
We use exponential growth formula
ξ(t) = y = ab^t
a = 45.1, b = 1+ξ, ξ= 2.3%, ξ(t) = 52.2
52.2/45.1 = (1.023)^t
We take log both side
Log(1.15742794) = tlog(1.023)
0.0634939619 = t0.00987563371
t = 0.0634939619/0.00987563371
t = 6.429355701569454
t = 6.4294 years

Complete question :
Victor left his house riding his bike at a speed of 18 km/h. When Victor was 1/2 km away from his house his brother Alex left the house riding at a rate of 24 km/h. How long will it take Alex to catch up with Victor?
Answer:
0.083333 or 5 minutes
Step-by-step explanation:
Victor's speed = 18 km/hr
Alex's speed = 24 km/hr
Alex left after Victor has moved a distance of 1/2 km
Time Alex will catch up with Victor :
Let time = x
distance at which Victor = Alex
(18 * x) + 0.5 = (24 * x)
18x + 0.5 = 24x
18x - 24x = - 0.5
-6x = - 0.5
x = 0.5 / 6
x = 0.0833333 hour
x = 0.0833333 *60 = 5 minutes
