Answer:

The number is 91

Step-by-step explanation:

Let x be the ones place digit and y be the tens place digit,

Then the number would be 10y + x,

We have,

y - x = 8

Possible values of y and x = { (8, 0), (9, 1) }

∵ 0 is not the digit of the number,

Hence, y = 9 and x = 1

Therefore, required number = 10(9) + 1 = 90 + 1 = 91

The requested number is: <u><em>91 </em></u>

<h3>Further explanation </h3>

Numbers are quantities used in measurements

Numbers in mathematics can be divided into several terms

  • 1. integer

numbers consist of positive, negative and 0 numbers

  • 2. natural numbers

numbers consisting of positive numbers, starting with number 1

  • 3. whole number

a number consists of positive numbers and zeros

  • 4. prime number

numbers that can only be divided by numbers themselves and the number 1

And examples of other numbers such as imaginary numbers, real numbers, rational numbers, etc.

Integers themselves consist of

  • 1. positive integers

the number to the right of the number 0 is 1,2,3 ...

  • 2. negative integers

the numbers to the left of the zeros are -1, -2, -3 ...

  • 3. number 0

From the above questions we can separate into several sections:

  • Write the 2-digit number that matches the clues

Means the number requested consists of 2 numbers, let us suppose the tens = x and the ones = y, so the number is<em><u> </u></em><em><u>xy </u></em>

  • My number has a tens digit that is 8 more than the ones digit

we can translate this sentence into the equation:

x = y + 8

So from the numbers 0 to 9 that have a difference of 8 to fill the values ​​of x and y are

  • 0 and 8
  • 1 and 9

because Zero is not one of my digits, the most appropriate numbers x and y are <u>1 and 9 </u>

So the number requested is \large{\boxed{\bold{xy=91}}

pat needs 14 sticks of pepperoni to make 28 pizzas.How many sticks of pepperoni are needed to make 36 pizzas
Marizza181 [45]

Answer:

18 sticks of pepperoni

Step-by-step explanation:

In order to solve this problem, we have to find out how many pepperoni sticks are needed for just 1 pizza. If it takes 14 sticks to make 28 pizzas, that means it takes only half a stick to make a single pizza.

Now that we have this information, we can multiply 1/2 by 36 to find out how many sticks of pepperoni are needed to make 36 pizzas.

\frac{1}{2} * 36\\\\\frac{1}{2} * \frac{36}{1} \\ =\\\frac{36}{2} \\ =\\\frac{18}{1}

Therefore, it takes 18 sticks of pepperoni to make 36 pizzas. I hope this helps! Have a lovely day!! :)

A 91 square foot bathroom has a length of 13 feet. what is the width of the bathroom
Radda [10]
<span>The answer is 7 ft. The bathroom has rectangular shape. The area (A) of a rectangle is the product of the width (w) and length (l): A = w * h. The bathroom is rectangular. We know that A = 91 ft^2 and l = 13 ft. Let's substitute them in the formula for the area: 91 ft^2 = w * 13 ft. w = 91 ft^2 : 13 ft. w = 7 ft. The width of the bathroom is 7 ft.Hope this helps. Let me know if you need additional help!</span>

A ball is kicked upward with an initial velocity of 32 feet per second. The ball's height, h (in feet), from the ground is model
stellarik [79]

Answer:

1.        t = 0.995 s

2.       h = 15.92  ft

Step-by-step explanation:

First we have to look at the following formula

Vf = Vo + gt

then we work it to clear what we want

Vo + gt = Vf

gt = Vf - Vo

t = (Vf-Vo)/g

Now we have to complete the formula with the real data

Vo = 32 ft/s      as the statement says

Vf = 0     because when it reaches its maximum point it will stop before starting to lower

g = -32,16 ft/s²        it is a known constant, that we use it with the negative sign because it is in the opposite direction to ours

t = (0 ft/s - 32 ft/s) / -32,16 ft/s²

we solve and ...

t = 0.995 s

Now we will implement this result in the following formula to get the height at that time

h = (Vo - Vf) *t /2

h = (32 ft/s - 0 ft/s) * 0.995 s / 2

h = 32 ft/s * 0.995 s/2

h = 31.84 ft / 2

h = 15.92  ft

Leona [35]

The probability that he first chooses an advanced book and then chooses a beginner book is 6/121.

<h3>Probability</h3>

Given:

Beginner book=2

Intermediate book=6

Instructional piano books=11

Advanced books=3

Hence:

Probability=(2×3)÷(11×11)

Probability=6/121

Therefore the probability that he first chooses an advanced book and then chooses a beginner book is 6/121.
