Whats The Value Of A?

Answers

Answer 1

Answer:

a = 69

Step-by-step explanation:

The linear pair equals 180 degrees.

a + 90 + 21 = 180

a + 111 = 180

a = 69

nice!

Answer 2

Answer:

A= 69 degrees

Step-by-step explanation:

if all those angles equal a total of 180 degrees then all you need to do is add the angles your given which in this case is 21 and a 90 degree angle which would equal 111 degrees, then subtract 111 from 180 and that would be the answer to the missing angle, which is 69 degrees.

21 + 90 = 111

180- 111 = 69

Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate what is her speed in miles per hour

Answers

Answer:

7.5 miles per hour

Step-by-step explanation:

Given: Kayla runs 3/4 mile in 1/10 hour assuming she runs at a constant rate

To find: speed in miles per hour

Solution:

Distance travelled by Kayla = [tex]\frac{3}{4}[/tex] mile

Time = [tex]\frac{1}{10}[/tex] hour

To find the speed in miles per hour, use the following formula:

Speed = Distance ÷ Time = [tex]\frac{\frac{3}{4} }{\frac{1}{10} }=\frac{3}{4}(10)=7.5[/tex] miles per hour

A rectangular dog pen has an area of 64xy square units. The width is 4y. Write an expression for the length.

Answers

Answer:

An expression for the length is:

[tex]l=16x[/tex]

Step-by-step explanation:

Given

Area of a rectangular dog pen = A = 64xy square units

Width = w = 4y

To determine

The length = l = ?

We know that the area of a rectangular object is

A = l × w

where w is the width and l is the length of the rectangle.

substituting w = 4y and A = 64xy in the equation

[tex]A=l\times w[/tex]

[tex]64xy\:=l\times 4y\:[/tex]

[tex]\:\:l=\frac{64xy\:}{4y\:\:}[/tex]

Divide the numbers: 64/4 = 16

[tex]l=\frac{16xy}{y}[/tex]

Cancel the common factor: y

[tex]l=16x[/tex]

Therefore, an expression for the length is:

[tex]l=16x[/tex]

What is a polynomial function?

A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the monomial equation, binomial equation, etc. ax+b is a polynomial.

Here,
according to the question,
area of the rectangle = x² + 2x - 3
area of the rectangle= (x - 1)(x + 3)

So,
Length  = x - 1 or x + 3
Width  =   x + 3 or x - 1

Thus, the area of the rectangle in the form of the product of two binomials is given as  (x - 1)(x + 3).

find the common ratio of the geometric sequence

Answers

Step-by-step explanation:

the formula to find common ratio is

r= second term/first term

The common ratio of the given the geometric sequence is -0.3

What is a geometric sequence?

A geometric progression, also known as a geometric sequence, is a sequence of non-zero numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.

Given that, a geometric sequence, is -162,54,-18.6,... we need to find the common ratio,

In a standard geometric sequence, a₁, a₂, a₃, a₄, a₅..... the common ratio is given by :-

a₂ / a₁ = a₃ / a₂ .... = r

Here, r = -54/162 = -18.6/54 = -0.3

Hence, the common ratio of the given the geometric sequence is -0.3
