Answer: 27 in^2.

Step-by-step explanation: To simplify this problem, we can split the figure into two rectangles. We can split the figure into a 3x3 square and a 2x9 rectangle. We can calculate these individual areas and then add them up to find the area of the entire figure. 3*3 = 9 and 2*9 = 18. 9 + 18 = 27, so 27 in^2.

Hello.

Plug in the value of p:

[tex]\mathrm{-10=10-3y}[/tex]

Now, all we have to do is solve the equation for y.

First, let's add 10 to both sides:

[tex]\mathrm{-10+10=10+10-3y}[/tex]

[tex]\mathrm{0=20-3y}[/tex]

Now, add 3y to both sides:

[tex]\mathrm{3y=20}[/tex]

Divide both sides by 3:

[tex]\Large\boxed{y=\frac{20}{3} }[/tex]

I hope it helps.

Have a nice day.

Step-by-step explanation:

40 - 5 = 35 years till the son will be 40, his fathers age

40+35 = 75, the dad's age 35 years in the future when the son is 40

Step-by-step explanation:

Our equation;

[tex]-5=\frac{y-7}{9}[/tex]

Multiply each side by 9 to remove the fraction;

Answer:

Quadrant 1: 36°

Quadrant 2: 144°

Quadrant 3 (Given): 216°

Quadrant 4: 324°

Step-by-step explanation:

A 216° angle in standard position has its terminal side in quadrant 3 since 216° is between 180° and 270°.

216° - 180° = 36°

The reference angle for 216° is 36°

Quadrant 1: 36°

Quadrant 2: 180° - 36° = 144°

Quadrant 3 (Given): 216°

Quadrant 4: 360° - 36° = 324°

Answer:

You can calculate Interest on your loans and investments by using the following formula for calculating simple interest: Simple Interest= P x R x T ÷ 100, where P = Principal, R = Rate of Interest and T = Time Period of the Loan/Deposit in years.

Formula: Simple Interest=P×r×t where: P=Principal amount; r=Annual interest rate; t=...

Principal Amount: Principal Amount remains constant on Simple Interest

Meaning: Simple Interest is calculated on the Principal Amount for the entire tenure

Calculation: It is easy to calculate Simple Interest

Answer:

To calculate simple interest, you can use a specific formula:

I (interest) = p (principal) x r (rate) x t (time)

Important: Rate is always a decimal, and time must be a compatible unit that matches with the rate (months, years, etc.).

Answer: 7

Step-by-step explanation:

Measurements are the metric units of an item, quantity or object

Beetles

The beetle covers two marks in a total length of 1 inch of 4 marks

So, the measurement of the beetle is:

[tex]Beetle = \frac{2\ inch}{4}[/tex]

Evaluate the quotient

[tex]Beetle = 0.5\ inch[/tex]

Ladybugs

The ladybug covers one mark in a total length of 1 inch of 4 marks

So, the measurement of the ladybug is:

[tex]Ladybug = \frac{1\ inch}{4}[/tex]

Evaluate the quotient

[tex]Ladybug = 0.25\ inch[/tex]

Butterfly

The butterfly covers four marks in a total length of 1 inch of 4 marks

So, the measurement of the butterfly is:

[tex]Butterfly= \frac{4\ inch}{4}[/tex]

Evaluate the quotient

[tex]Butterfly =1\ inch[/tex]

Hence, the length of the butterfly is 1 inch

https://brainly.com/question/2004114

Step-by-step explanation:

Length = L

Width = W

L=8 more than 2W

L = 8 * 2W

L = 16W

Perimeter = 96

perimeter is the lengths of all sides added together

so

2L + 2W = 96

we have

L = 16W

2L + 2W = 96

let's do substitution

put what L = into 2L + 2W = 96

so

2(16W) + 2W = 96

can you rearrange that to get w
