What is the unit fraction for 12/84

Answers

Answer 1

Answer: To simplify 12/84 find the greatest common factor, the greatest factor shared by both numbers. In this case, it is 12 itself. Divide both sides by 12 to get 1/7.

What is the value of y?114Answer:

Answers

Answer:

value of y is, $57^(\circ)$

Step-by-step explanation:

Exterior angle property of a triangle says that:

Sum of the two opposite interior angles.

From the given triangle:

Sum of two opposite interior angles = y +y = 2y

Since, 114 degree is an exterior angle of a triangle,

By Exterior angle property of a triangle :

$2y = 114$

Divide both sides by 2 we have;

y = 57 degree

Therefore, the value of y is, $57^(\circ)$

The opposite interior angles of the given triangle measure 57° each. So, the value of y is 57.

A triangle is one of the most basic geometric figures. It has 3 edges, 3 angles, and 3 vertices. The angle sum property of a triangle states that the sum of all three angles of a triangle is 180°. The property of triangles used in this question is that the sum of interior opposite angles measures the same as the exterior angle.

Since the sum of opposite interior angles is equal to the exterior angle, therefore in the given triangle,

$114^o = y^o + y^o\n114^o = 2y^o\ny^o = (114^o)/(2) \ny^o = 57^o$

Therefore, the value of y is 57.

8k-1=15 ? Help I have a question were we have to work this out what do I do?

Answers

$8k-1=15\ \ \ \ /+1\n\n8k-1+1=15+1\n\n8k=16\ \ \ \ /:8\n\n8k:8=16:8\n\nk=2$

you have to add 1 to the -1 and you will get 0.What you have to do next is also add 1 to 15 because you want a variable on one side and a number on the other.So now you have 8k=16. So you divide 8 to 8k and you get nothing divide 8 and 16 and your answer for k =2 hope you get it right.trust mw it is very easy when you get use to it

How do you solve a quadratic equation?

Answers

Oh that's easy, all you have to do is use the quadratic equation :)
ax^2+bx+c
A would be the number squared, b would be the number with just an x and c would be the single number :) Look at the attachment and you can see how to set it all up.
Hope this helps and could you mark me as the brainliest?

if in ax^2+bx+c=0 form then
use quadratic formula
x= $\frac{-b+ \sqrt{b^(2)-4ac} }{2a}$ or $\frac{-b- \sqrt{b^(2)-4ac} }{2a}$

Sam counted his heartbeats while resting. His heart beat 220 times in 4 minutes. Sam's heart beat at the same rate for the 4 minutes.

Answers

The equation for the number of beats per minute is 55 beats per minute

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the total number of beats be = A

Now , the value of A = 220 beats

The total time required for Sam to have 220 beats = 4 minutes

So , the number of beats of Sam in 1 minutes is calculated by

The equation will be

The number of beats of Sam in 1 minutes is = total number of beats / total time required for Sam to have 220 beats

The number of beats of Sam in 1 minute is = 220 / 4

The number of beats of Sam in 1 minute is = 55 beats per minute

Therefore , Sam would have 55 beats every minute or 55 beats per minute

And for the period of 4 minutes , Sam would have

Number of beats for 4 minutes = number of beats of Sam in 1 minute x 4

Number of beats for 4 minutes = 55 x 4

Number of beats for 4 minutes = 220 beats in 4 minutes

Hence , The equation for the number of beats per minute is 55 beats per minute

The ratio of Ed's toy cars to Pete's toy cars was initially 5:2. After Ed gave 30 toy cars to Pete, they each had an equal number of cars. How many toy cars did they have altogether?

Answers

Answer:

140 toy cars

Step-by-step explanation:

The ratio of Ed's toy car to Pete's toy car is initially given as 5:2

Ed gave Pete a total number of 30 cars

Let x represent the greatest common factor that exists between both number

Number of Ed's car is represented as 5x

Number of Pete car is represented as 2x

Since they each have an equal number of cars which is 30 then we can solve for x as follows

5x-30=2x+30

Collect the like terms

5x-2x= 30+30

3x= 60

Divide both sides by the coefficient of x which is 3

3x/3=60/3

x=20

Ed's car is 5x, we substitute 20 for x

5(20)

= 100 cars

Pete car is 2x,we substitute 20 for x

2(20)

= 40 cars

Therefore, the total number of cars can be calculated as follows

= 100+40

= 140 toy cars

Hence they have 140 toy cars altogether

Answer:

140
