Households in a city produced a total of 125 000 tonnes of waste in 2017. The total amount of waste is expected to fall by 2% each year.


Calculate the total amount of waste these households are expected to produce in 2020.


(3 marks)

Answers

Answer 1

Using an exponential function, it is found that the total amount of waste these households are expected to produce in 2020 is of 117,649 tones.

What is an exponential function?

A decaying exponential function is modeled by:

[tex]A(t) = A(0)(1 - r)^t[/tex]

In which:

A(0) is the initial value.r is the decay rate, as a decimal.

In this problem, we have that:

The households produced a total of 125 000 tonnes of waste in 2017, hence A(0) = 125000.The total amount of waste is expected to fall by 2% each year, hence r = 0.02.

Thus, the equation is:

[tex]A(t) = 125000(1 - 0.02)^t[/tex]

[tex]A(t) = 125000(0.98)^t[/tex]

2020 is 3 years after 2017, hence the amount is:

[tex]A(3) = 125000(0.98)^3 = 117649[/tex]

The total amount of waste these households are expected to produce in 2020 is of 117,649 tones.

Answers

Answer:

The original temperature was -18°F

Step-by-step explanation:

x°F + 24°F = 6°F

or, x°F = 6°F - 24°F

The perimeter of a basketball court is 90 meters and the
length is 6 meters longer than twice the width. What are the
length and width?
a
What is the width?
m
What is the length?
m

Answers

Answer:

w = 13 m

l = 32

Step-by-step explanation:

let 'w' = width

let '2w+6' = length

P = 2l + 2w

90 = 2(2w+6) + 2w

90 = 4w + 12 + 2w

90 = 6w + 12

78 = 6w

w = 13

length = 2(13) + 6  → 32

l = 32

check:

2(13) + 2(32) should equal 90

26 + 64 = 90

90 = 90 checks out

Answers

Answer:

A) 1:2

B) 3:5

C) 5:4

D) 17:5

Step-by-step explanation:

Step 1) Convert the decimal number to a fraction

Step 2) Multiply the numerator and denominator by 10 to eliminate the decimal point.

Step 3) Simplify the fraction in the previous step by dividing the numerator and the denominator by the greatest common factor (GCF)

Step 4) Convert the fraction in the previous step to a ratio by replacing the divider line with a colon

Heres an example. I'll do the last one.

(3.4 x10) /(1 x 10)= 34/10

34 /2 = 17

10/2  = 5

P ≈ 102.83 cm

Step-by-step explanation:

The window is practically a semi-circle. The formula for the perimeter of a semi-circle is πr + d.

*Remember that d (diameter) = 2 · r (radius)

Let's plug in everything that we know into the formula!

r = 20

d = 2(20) → 40

π(20) + 40 = 102.8318531

Now lets round the answer to the hundredths place.

102.8318531 → 102.83

Answer:

62.83 (estimate)

Step-by-step explanation:

The equation for the perimeter of a circle (also called circumference) is 2 times pi times the radius, or pi times the diameter. Since the window is a semi-circle, you divide the result by two.

[tex]2\pi r\\2(20)\pi = 40 \pi\\40\pi= 125.6\\125.663706144/2=62.83[/tex]

Jackson is two times older than Shelly if the sum of their ages is 18 how old is Jackson

Answers

Answer:

jackson is 12

Step-by-step explanation:

let the age be represented by x

jackson is 2 times older than shelly so

2x is jackson’s age and x is shelly’s age

since the sum of their ages is 18 then:

2x + x = 18

solve:

3x = 18 ➔ divide by 3 on both sides

x = 6

so now we know shelly is 6

jackson is 2 times older than her so:

2(6) = 12

hope this hello and hope it is right

Answer:

12

Step-by-step explanation:

since we know that Jackson is 2x Shelly - we can use trial and error.

for instance,

let's suppose Shelly is 6; that means that Jackson must be 12 (6 x 2)

we can check this answer by adding the two;

12 + 6 = 18

therefore, Jackson is 12

Step-by-step explanation:

Given the following question:

In order to find the answer to the question we have to subtract the initial amount of sugar by the amount of sugar Mike has left over after baking the cakes.

[tex]5\frac{2}{3}-2\frac{4}{5}[/tex]

To subtract fractions, we have to convert the mixed numbers into improper fractions and then find the least common denominator (LCD) to solve.

[tex]5\frac{2}{3} =3\times5=15+2=\frac{17}{3}[/tex]
[tex]2\frac{4}{5} =5\times2=10+4=\frac{14}{5}[/tex]
[tex]\frac{17}{3} -\frac{14}{5}[/tex]

Find the least common multiple:

[tex]LCD=15[/tex]

[tex]14\times3=42[/tex]

Subtract the numerators:
