Answer:

14 x 14 = 196

10 x 14 x 1/2(basically just dividing by 2) = 70

70 x 4(four sides of triangles) = 280

Now let's add the areas together:

196 + 280 = 476 cm^2 is your answer.

Answer:

$11

$39

Step-by-step explanation:

Amount Andre has = $7

Amount his grandmother pays him every week = $4

Amount Andre needs to buy a skateboard = $50

how much money does Andre have after the week?

Amount of money Andre has after the week = Amount Andre has + Amount his grandmother pays him every week

= $7 + $4

= $11

Amount of money Andre has after the week = $11

Amount Andre needs more to buy the skateboard = Cost of the skateboard - Amount of money Andre has after the week

= $50 - $11

= $39

Amount Andre needs more to buy the skateboard = $39

Answer:

28 miles per gallon

560/20=28

Step-by-step explanation:

Plz give me brainliest

Number of miles a car travels are 28.

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken.

Number of gallons of gas = 20

A car with 20 gallons of gas can drive 560 miles

Based on the given conditions,

= [tex]\frac{560}{20}[/tex]

= 28

Hence, number of miles are 28.

Answer:

Volume = 2512 km³

Volume = 800π km³

Step-by-step explanation:

Volume Cylinder = Area circle * height

Let's input the info

Formula for the Area of a circle = πr²

Area circle = π*100

Since it asks to leave in terms of π or tenths ill give both.

Area circle = 100π

Area circle = 314

Volume = 100π * 8

Volume = 800π

Volume = 314 * 8

Volume = 2512

Units = km³

Volume = 800π km³

Volume = 2512 km³

Answer:

571

Step-by-step explanation:

We solve using z score.

z = (x-μ)/σ, where

x is the raw score = ?

μ is the population mean = 480

σ is the population standard deviation = 70

z = 1.3

Hence,

= 1.3 = x - 480/70

Cross Mulitiply

1.3 × 70 = x - 480

91 = x - 480

x = 480 + 91

x = 571

Therefore, Marulla's raw score is 571

Answer:

a) $161.8

b i) Approximately 327.7 hours

ii) The cost of saving is less but the opportunity cost of saving can be higher with regards to technology and regulation

Step-by-step explanation:

The amount Mary would like to save, FV = $10,000

The time Mary over which Mary intends to save the amount, t = 5 years

Therefore, the number of monthly payments, n = 12

a) The amount in interest the bank pays compounding, i = 1.2% per annum

The amount that Mary will deposit each month is given as follows;

The compound interest formula is given as follows;

[tex]PMT = \dfrac{FV}{\left (\dfrac{ \left (1 + \dfrac{i}{12} \right )^n - 1}{ \dfrac{i}{12}} \right)}[/tex]

Where;

PMT = The monthly payment

Therefore, we get;

[tex]PMT = \dfrac{10,000}{\left (\dfrac{ \left (1 + \dfrac{0.012}{12} \right )^{60} - 1}{ \dfrac{0.012}{12}} \right)} \approx 161.8[/tex]

PMT = 10,000/((1 + 0.012/12)^(60) - 1)/(0.012/12)) ≈ 161.8

The amount she needs to deposit monthly, PMT ≈ $161.8

b i) Given that the minimum wage varies and we have a minimum wage here is officially approximately $79, which is 160 hours a month work

The number of hours work needed = 161.8/79 × 160 ≈ 327.7 hours a month approximately

b ii) Given that the interest rate for saving is lower than the interest rate for borrowing, the amount paid by saving is much lesser than the amount paid back when borrowing, therefore, it is more cost effective to save

However, while saving, changes may take place, such as the use of what is being saved for, therefore, it can be more beneficial to borrow and make use of the items now while they are still available and acceptable, such as the drive towards net zero is making fuel based cars less popular with the drive being towards electric cars.

Given:

Principal = $1500

Time = 10 year

Amount after interest compounded continuously = $3935.36

To find:

The rate of interest.

Solution:

The formula for amount after continuous compound interest is:

[tex]A=Pe^{rt}[/tex]

Where, P is principal, r is the rate of interest in decimal and t is time in years.

Putting [tex]P=1500,A=3935.36,t=10[/tex] in the above formula, we get

[tex]3935.36=1500e^{r(10)}[/tex]

[tex]\dfrac{3935.36}{1500}=e^{10r}[/tex]

[tex]2.6236=e^{10r}[/tex]

Taking ln on both sides, we get

[tex]\ln(2.6236)=\ln e^{10r}[/tex]

[tex]0.9645=10r[/tex]                   [tex][\because \ln e^x=x][/tex]

Divide both sides by 10.

[tex]\dfrac{0.9645}{10}=r[/tex]

[tex]0.09645=r[/tex]

The rate of interest in percentage is:

[tex]r=100\times 0.09645[/tex]

[tex]r=9.645\%[/tex]

Therefore, the required rate of interest is 9.645%.
