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?
Answers
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

Answers
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

5 min

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 promoter buys advertising in units of $30,000 each. If he buys two units of broadcast TV, one unit of cable TV, and two units of radio, how much does he spend in advertising?
Answers
Answer:
$150,000
Step-by-step explanation:
The first step is to calculate the total number of units
= 2 +1 +2
= 5
If he buys at the rate of $30,000 for one unit then the total money spent on advertising can be calculated as follows
= 30,000 × 5
= 150,000
Hence the promoter spends $150,000 on advertising

The perimeter of a triangle is 21. The smallest side is 3. The 2nd side is twice the smallest side. The 3rd side is 6 more than the 2nd side. Write an equation to solve for the perimeter. Then find the ____ and ____.
Fill in the blanks.
Answers
Answer: See explanation
Step-by-step explanation:
From the question, we are informed that the smallest side is 3 and that the 2nd side is twice the smallest side. This means that the second side will be:
= 3 × 2 = 6
The 3rd side is 6 more than the 2nd side. The 3rd side will be:
= 6 + 6 = 12
The perimeter of a triangle is the addition of its sides. Therefore, the perimeter is:
= 3 + 6 + 12
= 21
The sides are:
1st side = 3
2nd side = 6
3rd side = 12.

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.

(2,-8) and has a slope of 4
Answers
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

Answers
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.

angle A: most likely 20 degrees
angle B: most likely 100 degrees
explanation:
a full circle is 360 degrees.
the angle on the bottom left-hand corner is most obviously a 90 degree angle.
the angle on the right hand corner labeled “75 degrees” is the same as the angle in the top left hand corner, as they are mirrored. this means:
360-90-75-75=120
there is 120 degrees left for the two values that we are looking for. since B is an obtuse angle, I would say that angle B is most likely 100 degrees and the smaller angle (angle A) would be 20 degrees.
hope this helps you!
xoxo
Answer:
Angle A = 15
Angle B: 105
Step-by-step explanation:
Angle A and 75° add up to 90°
75 + x = 90
x = 90 - 75
x = 15
Angle B and 75° add up to 180°
75 + x = 180
x = 180 - 75
x = 105
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?
Answers
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.
