when five is added to three more than a certain number,the result is 19.what is the number?

Answers

Answer 1
when 5 is added to 3 more then a certain number, the result is 19

x + 3 + 5 = 19
x + 8 = 19
x = 19 - 8
x = 11 <== ur number

Answer 2
Five is added to three more than a certain number, resulting in 19

5 + 3 + (x) = 19

8 + x = 19

x = 19 - 8 = 11


Thus, the certain number is 11.

This square has the hypotenuse of a right triangle as one of its sides.

The estimated value of the length of the hypotenuse is units. The estimated value of the area of the square is square units.

(Hint: The hypotenuse is the side opposite the right angle. To find the hypotenuse of a right triangle, use the Pythagorean Theorem, c2= a2 + b2.)

Answers

Final answer:

The question is about using the Pythagorean Theorem to calculate the length of the hypotenuse of a right triangle. It also asks how to calculate the area of a square when the hypotenuse of the right triangle is one of its sides. The hypotenuse's length would be useful to determine the square's area, as the square's area is calculated as the square of the length of one side.

Explanation:

The subject of this question is Mathematics, and it is appropriate for a High School level student. The question is discussing a scenario where a square has the hypotenuse of a right triangle as one of its sides, and the student is asked to estimate the value of the length of the hypotenuse and calculate the area of the square.

To solve this problem, we will use the Pythagorean Theorem, which states that in a right triangle, the square of the length of the hypotenuse (let's call it 'c') is equal to the sum of the squares of the lengths of the other two sides (let's call them 'a' and 'b'). In other words, c² = a² + b². The length of the hypotenuse is the square root of this sum, √(a² + b²).

Since we aren't given specific lengths for the sides of the triangle, I cannot provide exact values. However, let's say that the length of the hypotenuse is 'd', then the area of the square, which is calculated as the length of one side squared (d²) would be equal to the given value.

How many books does Matt have to sell to make $30 for the week?

Answers

Matt needs to sell approximately 28 books to make $30 for the week.

To find the number of books Matt needs to sell to make $30 for the week, we need to use the given information that Matt gets $6 for selling 9 books and $9 for selling 11 books.

Let's first find the amount of money Matt makes for each book:

For 9 books, Matt makes $6, so he makes $\frac{6}{9} = \frac{2}{3}$ dollars per book.

For 11 books, Matt makes $9, so he makes $\frac{9}{11}$ dollars per book.

Now, we can set up an equation to find the number of books Matt needs to sell to make $30:

2/3 x + 9/11 x=30

where (x) is the number of books Matt needs to sell.

Simplifying the equation, we get:

x = 28

Therefore, Matt needs to sell approximately 28 books to make $30 for the week. Since he cannot sell a fraction of a book, he would need to sell either 28 or 29 books to make $30.

Fiona and her friends went to a smoothie shop. They ordered three strawberry smoothies and two protein shakes for a total of $24.00. Last week they ordered one strawberry smoothie and four protein shakes for a total of $25.50. The system that represents their purchases is below. x + 4y = 25.50 3x + 2y = 24.00 What is the price of a protein shake? $3.75 $4.50 $4.95 $5.25

Answers

Answer:  Fourth option is correct.

Step-by-step explanation:

Since we have given that

[tex]x+4y=25.50------------------(1)\\\\3x+2y=24.00-----------------------(2)[/tex]

Here, x is the number of strawberry smoothies.

and y is the number of protein shakes.

So, using elimination method, we get that,

Multiplying 2 by eq(2), we get that

6x+4y=48---------------(3)

From eq(1) and (3), we have

[tex]x+4y=25.50\\\\6x+4y=48\\\\-----------------------------------\\\\-5x=-22.5\\\\x=\dfrac{22.5}{5}\\\\x=4.5[/tex]

Put the value of x in eq(1), we get that

[tex]4.50+4y=25.50\\\\4y=25.50-4.50\\\\4y=21\\\\y=\dfrac{21}{4}\\\\y=5.25[/tex]

Hence, the price of protein shake is $5.25.

Thus, Fourth option is correct.

Answer:

D. $5.25

Patti is using mental math to evaluate the expression (70+12.8+30)+6.1. She recognizes that the expression will be easier to simplify if she can combined 70 and 30 before she works with other numbers. How do the properties of operation allow pattie to take that approach?

Answers

Answer: Explanation is given below.

Step-by-step explanation: Given that Patti is using mental mathematics to evaluate the expression (70+12.8+30)+6.1 and recognises that it will be easier to simplify if she can combined 70 and 30 in the beginning. We are to explain the way in which the properties of operation allow Patti to take that approach.

We will be using the following associative property of real numbers:

[tex](a+b+c)+d=(a+c)+(b+d).[/tex]

Therefore, the simplification is as follows:

[tex](70+12.8+30)+6.1\\\\=(70+30)+(12.8+6.1)\\\\=100+18.9\\\\=118.9.[/tex]

Hence explained.

Answer:

She can use the commutative property to rewrite the expression as (70 + 30 + 12.8) + 6.1

Pat has nine cards. Frank has two more cards than Steve. Steve has 3 cards how many more cards does Pat have than Frank?

Answers

pat =9
steve = 3
frank = 5 (3+2)
9-5 = 4
answer is 4

Based on the information given, Pat has 4 more cards than Frank.

The number of cards that Pat has = 9 cards

Number of cards that Steve has = 3 cards

Since Frank has two more cards than Steve, the total number of cards that Frank has will be: = 3 + 2 = 5

In order to know the number of cards that Pat has more than Frank, we will have to calculate the difference between the cards that they've. This will be:

= Pat's card - Frank's card

= 9 - 5

= 4

Therefore, Pat has 4 more cards than Frank.

A ball always bounces to 3/5 of the height from which it falls. It falls from a height of 1meter how high will it rise after the second bounce?

Answers

this is the answer check it out
Final answer:

After the second bounce, the ball will rise to a height of 0.36 meter.

Explanation:

To find the height the ball will rise after the second bounce, we can use the given information that the ball always bounces to 3/5 of the height from which it falls. In this case, the ball falls from a height of 1 meter.

For the first bounce, the ball rises to 3/5 of 1 meter, which is 0.6 meter. For the second bounce, the ball will rise to 3/5 of 0.6 meter. To calculate this, we multiply 3/5 by 0.6 meter, which gives us 0.36 meter.

Therefore, after the second bounce, the ball will rise to a height of 0.36 meter.

The table below show 2 equations. Equation 1: 3x-1=7+2 Equation 2: 2x+1+4=3 which statement is true about the solution to the two equation?

Answers

You have not added your options, so I will just solve and hope that my answer is in your choices.

For the first equation we have:
3x-1=7+2
3x = 7+2+2
3x = 10
x = 10/2

For the second equation we have:
2x+1+4=3
2x = 3-4-1
2x = -2
x = -1

Therefore, there isn't a solution that satisfies both equations. Based on this, this system of equations has no solution.

A chess set is on sale for $75.00, which is 40% off of its original price. What was the original price of the chess set?

Answers

Okay, to solve this, let's use the variable 'p' to represent the original price:
Because we know the amount of discount and the percentage off, we know that 60% of the original price is $75.
Knowing this, we can write an equation:
0.6p = 75
There are multiple ways to solve this, but I'll just use the method I prefer
6p = 750
p = 750/6
p = 125
The original price of the chess set was $125

Alan travels 3/10 of his journey car. 3/20 by bicycle 1/12 by boat and walks the rest what fraction of the journey did he walk? If the journey is 140 km,how many km did he walk?

Answers

The denominators are: 10, 20, and 12
The LCD (lowest common denominator) is 60 as this is the smallest multiple of 10, 20, and 12.

Get each fraction to have a denominator of 60
3/10 = (3/10)*(6/6) = (3*6)/(10*6) = 18/60
3/20 = (3/20)*(3/3) = (3*3)/(20*3) = 9/60
1/12 = (1/12)*(5/5) = (1*5)/(12*5) = 5/60

The fractions 
3/10, 3/20, and 1/12
are equivalent to
18/60, 9/60, and 5/60
in that exact order

Add up the second set of fractions to get
(18/60) + (9/60) + (5/60) = (18+9+5)/60 = 32/60 = 8/15

The result of adding the fractions and reducing leads to 8/15 meaning that Alan takes 8/15 of the journey to use his car, bike and boat

The rest of the journey (7/15) is done walking
Multiply this with the total distance 140
(7/15)*140 = (7/15)*(140/1)
(7/15)*140 = (7*140)/(15*1)
(7/15)*140 = (980)/(15)
(7/15)*140 = (975+5)/15
(7/15)*140 = (975/15)+(5/15)
(7/15)*140 = (65)+(1/3)
(7/15)*140 = 65 & 1/3

The answer as a mixed number is 65 & 1/3
The answer as an improper fraction is 980/15
The approximate answer in decimal form is 65.33 (rounded to 2 decimal places)
