I Kinda Need Help And An Explanation Cant Understand

Answers

Answer 1

Answer:

look in explanation

Step-by-step explanation:

Seeing as most of your answers are wrong, I'll start from the beginning.

a rational number is a number that can be expressed as a fraction.

an integer is a  whole number.

an irrational number is a number that cannot be expressed as a fraction.

an integer is also always a rational number.

Using this, we can sort the values.

-77/11 can be simplified as -7, which is an integer.

the square root of 144 is 12, which is an integer.

0.25 is a decimal that can be expressed as a fraction, which makes it a rational number that is not an integer.

the square root of 20 is a value that cannot be expressed as a fraction, which makes it irrational.

17/4 is a fraction that is not a whole number, which makes it a rational number but not an integer.

finally, 2*the square root of 10 is irrational.

You and 3 friends are going to the country fair. You have a coupon that will save your group $20. If the total bill to get into the fair was $100, how much does one regular price ticket to the fair cost?

Answers

Answer:

30$

Step-by-step explanation:

lets assume you didn't have a coupon then the total bill would have been 120$

so for 4 friends including u the bill would have been 120$

: 4 friends = 120 $

for : 1 friend = x$

cross multiply

4x = 120 × 1

4x =120

divide both sides by the coefficient of x

x =120 \ 4

x = 30$

therefore: 1 friend = 30$

The left and right page numbers of an open book are two consecutive integers whose sum is 23. Find these page number.

Answers

Answers: The page numbers are 11 and 12

==========================================================

Explanation:

Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.

Let,

x = first page, some positive whole numberx+1 = second page, follows immediately after page x

Adding those two said pages will lead to 23

first + second = 23

(x) + (x+1) = 23

2x+1 = 23

2x = 23-1

2x = 22

x = 22/2

x = 11 is the first page

x+1 = 11+1 = 12 is the second page

Check: 11+12 = 23 which confirms the answers.

Find the value of x and y.

Answers

Answer:

x=25, y=19

Step-by-step explanation:

130+2x=180

x=25

54+2x+4y=180

y=19

Answer:

x = 25 , y = 19

Step-by-step explanation:

130° and 2x° are adjacent angles on a straight line and sum to 180° , so

130 + 2x = 180 ( subtract 130 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

--------------------------------------------------------------

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle , then

54 + 4y = 130 ( subtract 54 from both sides )

4y = 76 ( divide both sides by 4 )

y = 19

What is the value of T in this exterior angle

Answers

Answer:

t =30

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles.

t + (2t-28) = t+32

Combine like terms

3t -28 = t+32

Subtract t from each side

3t -28-t = t+32-t

2t -28 = 32

Add 28 to each side

2t-28+28 = 32+28

2t = 60

Divide by 2

2t/2 = 60/2

t =30

The price of an item yesterday was $130. Today, the price rose to $299. Find the percentage increase.

Answers

Answer:

130%

Step-by-step explanation:

Use the formula for percent change: difference = % * original price

To find the difference, you have to do 299 - 130, which is 169.

The original price is $130 because this is the price before it rose to $299.

Now, you have the equation 169 = % * 130.

We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.

130%

Step-by-step explanation:

Yesterday = $130.

Today = $299 .

((final price - initial price)/(initial price)) × 100%

= (($299 - $130)/$130) × 100%

= ($169/$130) × 100%

= $1,3 × 100%

= 1,3 × 100%

= 130%

(-1,7) is the answer I think

Answer:

So for the coorfinates of F, you have to see how far it is from y=1. The F is 2  points under the 1 so you have to count 2 above the 1. So the point would be (7,3). Same for the other ones. For example like D. It's 2 above 1 so its going to be 2 under which would result in (1, -1)
