Answer 1

Answer: the answer is d. the angle that is 140* and the angle it is right next to must equal 180. therefore you subtract 180-140 to get the measure of that interior angle. after doing that, you add the measure of the two interior angles to get the measure of

What is reciprocal of a fraction?

At first, it is important to know about fraction.

Suppose there is a collection of objects and a part of the collection has to be taken. The part which is taken is called fraction. In other words, part of a whole is called fraction.

The upper part of the fraction is called numerator and the lower part of the fraction is called denominator.

For example: $(4)/(7)$ is a fraction. Here, 4 is the numerator of the fraction and 7 is the denominator of the fraction.

Let p be a fraction. Reciprocal of p is a fraction in which if the fraction is multiplied by p, the result obtained is 1 (multiplicative identity)

Here,

$3(1)/(4) = (13)/(4)$

Let the reciprocal of $(13)/(4)$ be x

$(13)/(4) * x = 1\n\n13x = 1* 4\n\n13x = 4\n\nx = (4)/(13)$

Reciprocal of $3(1)/(4)$ is $(4)/(13)$

Which of the following expressions results in 0 when evaluated at x = 4?O A. (x - 10)(x - 4)
OB. (x + 4)(x - 10)
O C.
(x + 6)(x - 2)
OD. 4x(x-6)

Answers

Answer:

A. (x - 10)(x - 4)

Step-by-step explanation:

Let x=4

O A. (4 - 10)(4 - 4) = -6 * 0 = 0

OB. (4 + 4)(4 - 10) = 8* -6 = -48

O C.(4 + 6)(4 - 2) = 10 * 2 = 20

OD. 4*4(4-6)=16*-2 = -32

Answer:

A. (x - 10)(x - 4)

Step-by-step explanation:

The product is 0 if one of the factors is 0.

(4 - 10)(4 - 4)

= (4 - 10)*0

= 0

A business rents in-line skates and bicycles. During one day, the business has a total of 26 rentals and collects $485 for the rentals. If in-line skates are rented for $10 per day and bicycles are rented for $35 per day, find the number of pairs of stakes rented and the number of bicycles rented.

Answers

A business rents in-line skates and bicycles.

During one day the business has a total of 26 rentals and;

Collects $485 for the rentals.

In-line skates are rented for $10 per day and;

Bicycles are rented for $35 per day.

Solution:

Let the number of in-line skates rented be x and;

The number of bicycles rented be y.

x + y = 26 ... (i)

10x + 35y = 485 ... (ii)

This forms a system of linear equations (i) and (ii)

Solving this system by elimination;

We multiply (i) by 10 and (ii) by 1

10x + 10y = 260 ... (i)

10x +35y = 485 ... (ii)

Subtracting (ii) - (i) gives;

25y = 225 , y = 225/25 = 9

x = 26 - 9 = 17

The number of in-line skates rented were 17.

The number of bicycles rented were 9.
