Answers

Answer 1
Answer:

The length of the given rectangular is 21 inches while the width is 10.5 inches.

What is a rectangle?

A rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Let's say the length of a rectangle is L while the width is W

So,

Perimeter 2(L + W) = 63

And,

W = 1/2 L

By substitution,

2(2W + W) = 63

6W = 63

W = 10.5 inches.

And,

L = 2(10.5) = 21 inches.

Hence "The length of the given rectangular is 21 inches while the width is 10.5 inches".

Answer 2
Answer:

Answer:

Width is 10 1/2 inches and the length = 21 inches.

Step-by-step explanation:

Let the width be x then the length us 2x inches.

Perimeter = 2x + 2(2x) = 63

6x = 63

x = 10 1/2 inches.

What is the solution to the equation? 3q 5 = -2q 20 a. q = 3
b. q = 5
c. q = 15
d. q = 25

Answers

You're missing some operators there between the variable and the number which will change it drastically. I'll give you all the options.

3q+5=-2q+20

5q = 15

q=3

3q-5=-2q-20

5q = -15

q = -3

3q+5=-2q-20

5q = -25

q = -5

3q-5=-2q+20

5q = 25

q = 5

the ratio of the measures of three angles in a triangle is 10:3:7 find the measure of the largest angle

Answers

Answer:

90°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180°

sum the parts of the ratio 10 + 3 + 7 = 20

divide 180 by 20 to find the value of one part of the ratio

= 9° ← 1 part of the ratio

the largest angle is the one with 10 parts of the ratio, hence

10 parts = 10 × 9° = 90° ← largest angle

7.0 ft

Answers

Answer:

6.3 ft

Step-by-step explanation:

We are given,

the central angle of the arc = radians; and

radius of the arc = 6ft

Therefore using these values, we can find the length of the long arc.

Length of the arc = 6 × / 3

Lenth of the arc = = 2 × 3.14 = 6.28

Therefore, the length of the arc, rounded to the nearest tenth is 6.3 ft.

How much would $400 invest at 5% interest compounded annually be worth after 6 years? Compound interest formula: A(t) = P(1 + i)t 1. Write the numbers. Principal = , interest rate= , time = 2. Find the total amount of money that the investor would have after 6 years. Show your work using the equation editor.

Answers

The total amount of money that the investor would have after 6 years is $936.04.

Given the following data:

  • Principal = $400
  • Interest = 5% = 0.05
  • Time = 6 years

To find the total amount of money that the investor would have after 6 years:

Mathematically, compound interest is given by the formula:

Where;

  • A is the future value.
  • P is the principal or starting amount.
  • i is the annual interest rate.
  • t is the number of years for the compound interest.

Substituting the given parameters into the formula, we have;

Future value, A = $536.04

Now, we can find the total amount of money that the investor would have after 6 years:

Total amount = $936.04

Answer: 1. Principal = $400, interest rate= 5% = 0.05 , time = 6 years

2. The total amount of money that the investor would have after 6 years will be $ 536.04 .

Step-by-step explanation:

Given : Compound interest formula:

, where P= Principal  amount

i= Rate of interest ( in decimal )

t= time

As per given : Principal = $400, interest rate= 5% = 0.05 , time = 6 years

i.e. P = 400 , i=0.05 , t= 6

Put these values in compound interest formula , we will get

Hence, the total amount of money that the investor would have after 6 years will be $ 536.04 .
