What Is The Value Of K?help!!!!

Answers

Answer 1

Answer:

k = 10°

Step-by-step explanation:

[tex] {115}^{o} = {(4k + 5)}^{o} + {(6k + 10)}^{o} \\ [/tex]

An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

[tex] {115}^{o} = {(4k + 5)}^{o} + {(6k + 10)}^{o} \\ {115}^{o} = 4k + 5 + 6k + 10 \\ {115}^{o} = 10k + 15 \\ {115}^{o} - 15 = 10k \\ {100}^{o} = 10k \\ \frac{100}{10} = k \\ {10}^{o} = k \\ [/tex]

The radius is 7. Find the circumference of p. Leave your answer in terms of pi.

Answers

Answer:

Step-by-step explanation:

Hi there!

According to the question;

radius (r) = 7

We know,

Circumference (c) = 2πr

                              = 2π * 7

                              = 14π

Therefore the circumference of p is 14π.

Step-by-step explanation:

Triangle Outer Perimeter:

5ft + 5ft = 10ft

Semi-Circle Outer Perimeter:

First let's find the circumference of the entire circle:

Circumference = 2πr

Circumference = 2π * 3

Circumference = 6π

Circumference = 6(3.14)

Circumference = 18.84

Now to find the perimeter of the semicircle, we divide that value by two:

6π = 18.84

(6π)/2 = (18.84)/2

3π = 9.42 ft

Total Outer Perimeter:

10 ft + 9.42 ft = 19.42 ft

The expression for the total cost will be y = 80 + 60x.

What is an expression?

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a plumber has a fixed call-out rate of $80 and an hourly rate of $60.

The expression will be formed by assuming the hourly rate to be x dollars. The expression will be written as below:-

y = 80 + 60x

Here y is the total cost 80 is the fixed cost and x is the hourly rate.

Therefore, the expression for the total cost will be y = 80 + 60x.

If a rectangular house is 50 feet wide and contains 2,500 sq/ft, what is its depth?

Answers

Answer:

50 ft

Step-by-step explanation:

The area of a rectangle = width × depth

area = 2,500 ft²

width = 50 ft

Substitute the values into the formula:

2,500 = 50 × depth

Divide both sides by 50 to find the depth:

2500 ÷ 50 = depth

depth = 50 ft

Which of the following rational algebraic equation is transformable to a quadratic equation?​

Answers

Answer:

Option A

Step-by-step explanation:

Possible options are A and B as the other two have no variables in their denominators and the numerators are of degree 1.

Now, option A, it has two different denominators involving the variable s. If you multiply all the terms by the product of the two  8s(s + 2), then you get a quadratic equation.

The option B. If you perform same operation, multiply all the terms by m(m + 1) this will result in degree 3 polynomial, which is a cubic equation but not the quadratic.

So the only option is A

Simplify 10/16 to the lowest terms and find an equivalent fraction that has a denominator of 32.

Answers

Answer:

5/8,  20/32

Step-by-step explanation:

Divide 10/16 by 2 as that is the GCF (greatest common factor) = 5/8

To find an equivalent fraction with a denominator of 32 multiply 10/16 by 2 = 20/32

Answer:

5/8; 20/32

Step-by-step explanation:

10/16 = (5 · 2)/(8 · 2) = 5/8 lowest term

 equivalent fraction  5/8 = ?/32  means 32÷ 8 = 4 × 5 =20

5/8 = 20/32

If using 10/16 = ?/32     means 32 ÷ 16 = 2 × 10 = 20

Again 10/16 = 20/32
