is 11/4 irrational or rational
Answer: rational
Step-by-step explanation:
Answer:
rational
Step-by-step explanation:
irrational means that the decimal digits are not in a pattern. 11/4 is equal to 2 3/4 which is also equal to 2.75. Since we can predict the coming digits, (which are all 0) it means that 11/4 is, indeed rational.
two glasses of milk and 3 snack bars have a total of 78 carbohydrates (carbs), and 4 glasses of milk and 3 snack bars have a total of 96 carbs. Determine how many carbs are in one glass of milk and in one snack bar
Answer:
Each glass of milk is 9 carbs.
Each snack bar is 19.7 carbs.
Step-by-step explanation:
1. I know that 2 glasses of milk with 3 snack bars is 78 carbs.
The next part of the sentence has two times the amount of milk with the same amount of snack bars for 96 carbs.
Now, I will find the difference in the amount of carbs.
96 - 78 = 18 carbs.
So two glasses of milk = 18 carbs.
18 ÷ 2 = 9 carbs
So, each glass of milk is 9 carbs.
2. Since we know this, we can subtract the amount of carbs from the glasses of milk from the total amount of carbs.
78 - 19 = 59
In the first scenario, there are 59 carbs per 3 snack bars.
To find the amount of each snack bar, divide 59 by 3.
59 ÷ 3 = 19.7 when rounded to the nearest tenth.
Therefore, each snack bar is 19.7 carbs.
Answer:
glass of milk = 9 carbohydrates
snack bars = 20 carbohydrates
Step-by-step explanation:
Let s be snack bars and g be the glasses of milk.
3s + 2g = 78
3s + 4g = 96
-1(3s + 2g) = -1(78)
- 3s - 2g = - 78
- 3s - 2g = - 78
3s + 4g = 96
2g = 18
g = 18/2
g = 9
3s + 2g = 78
3s + 2(9) = 78
3s + 18 = 78
3s = 78 - 18
3s = 60
3s/3 = 60/3
s = 20
Check: g = 9; s = 20
3s + 2g = 78
3s + 4g = 96
3(20) + 2(9) = 78
60 + 18 = 78
78 = 78
3(20) + 4(9) = 96
60 + 36 = 96
96 = 96
So, the solution is g = 9; s = 20

Answer this CORRECTLY! The question will be placed first, I'll place the graphs and in order from A - D, then I want to see what you can do. 100 Points Sounds Nice....
Answer:
Option D
Step-by-step explanation:
x-axis is the Celsius and
y-axis is the Farenheit
If you look at the points in the table, you will notice that the only graph that contains points (0,32), (10,50), (15,59) is option D. You can assume point (30,86) will also be in the graph by looking at the way the line is going.
This is the same as graphing a line with a point (x,y).

what would 2 to the exponent of 3 simplify to ?
Answer:
8
Step-by-step explanation:
2*2=4
2*2=4
=8
Answer: 8
Step-by-step explanation: The example above is 2 raised to the third power (raised to the third power means the exponent is 3). This is equivalent to the multiplication problem below, because there is a 1 multiplied by 2 three times. As you can see, the 1 * 2 * 2 * 2 can be simplified to 8 which is the answer to the problem.
Un joven retira el 25% de sus ahorros y gasta el 33.3% en adornos para su
nueva casa. Si los adornos costaron $250.00, ¿Cuántos dólares tenia en el
banco?
Answer:
$3003.2
Step-by-step explanation:
Step 1
Paso 1
Averiguamos cuánto era el 25% de sus ahorros.
Se nos dice en la pregunta que gastó el 33.3% en decoraciones para su nueva casa y si los adornos cuestan $ 250.00.
Esto significa
33.3 % × x = 250
33.3 x/ 100 = 250
Cruz multiplicar
33.3x = 250 × 100
x = 25.000 / 33.3
x = 750.75075075
Por lo tanto, la cantidad o el costo de los adornos = 33.3% del 25% de sus ahorros = $ 750.8
Paso 2
De la pregunta:
Un joven retira el 25% de sus ahorros y
Por lo tanto:
Sea y = monto total de sus ahorros
25/100 × y = $ 750.8
25y = 100 × 750.8.
y = 100 × 750.8 / 25
y = $ 3003.2
Por lo tanto, tenía $ 3003.2 en su cuenta.

Matthew invested $680 in an account paying an interest rate of 5.8% compounded daily. Assuming no deposits or withdrawals are made, how much money, to the nearest ten dollars, would be in the account after 11 years?
Answer:
Step-by-step explanation:
1290
Based on the amount invested, the rate, and the period of compounding, after 11 years, the account would be $1,290.
As the rate is compounded daily, the rate and the period need to be converted to daily figures:
Rate = 5.8% / 365 days = 5.8/365 %
Period = 11 x 365 = 4,015 days
The amount in 11 years is:
= Amount x ( 1 + rate) ^ period
= 680 x (1 + 5.8/365%) ⁴⁰¹⁵
= $1,286.965
= $1,290
In conclusion, the account would have $1,290.

The length of a rectangle is the same as the length of each side of a square.
The length of the rectangle is 4 cm more than 3 times the width of the rectangle.
The area of the square is 66 cm? more than the area of the rectangle.
Find the length and the width of the rectangle.
You must show all your working.
I searched your question and here is what I found:
Step-by-step explanation:
L = 4 + 3W (from the second condition)
L2 = 66 + LW (combining the first and third condition)
L2 = 66 + L(L-4)/3
3L2 = 198 + L2 -4L
2L2 + 4L -198 = 0
(2L - 18)(L + 11) = 0; discarding the negative root for lack of practicality , L = 9
from the first equation W = (L - 4)/3 = 5/3 = 1 2/3; 1.67
Hence the length of the rectangle is 9 cm and the width is 1.67 cm
check;
2nd condition; L = 4 + 3*1.67 = 9 (proven)
1st and 3rd condition; 92 = 66 + 9*1.67 = 81 (proven)
The length of the rectangle is 9 cm.
The width of the rectangle is 5/3 cm.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Rectangle:
Length = 3w + 4
Width = w
Area = (3w + 4)w
Square:
Side = 3w + 4
Area = (3w + 4)²
Now,
The area of the square is 66 more than the area of the rectangle.
This means,
(3w + 4)² = (3w + 4)w + 66
9w² + 16 + 24w = 3w² + 4w + 66
9w² - 3w² + 24w - 4w + 16 - 66 = 0
6w² + 20w - 50 = 0
2 (3w² + 10w - 25) = 0
3w² + 10w - 25 = 0
3w² + (15 - 5)w - 25 = 0
3w² + 15w - 5w - 25 = 0
3w(w + 5) - 5(w + 5) = 0
(3w - 5)(w + 5) = 0
w + 5 = 0 and 3w - 5 = 0
w + 5 = 0
w = -5 (rejected since its negative)
3w - 5 = 0
3w = 5
w = 5/3
Now,
Length.
= 3w + 4
= 3 x 5/3 + 4
= 5 + 4
= 9
Width = 5/3
Thus,
The length and width of the rectangle are 9 and 5/3.

Answer: 1.25 p , where p= Weight of Jordan's dog
Step-by-step explanation:
Let p = Weight of Jordan's dog .
Given: Emmett apostrophe's dog with 25% more than Jordan star.
Then, weight (in pounds) of Emmett apostrophe s dog = p +25% of p
= p +0.25 p [We divide a number by 100 to remove %]
= p(1+0.25)
= p(1.25)
=1.25 p
Hence, the expression represents the weight in pounds of Emmett apostrophe's dog=1.25 p

The possible values of x are positive integers that are less than 14
The perimeter of a figure is the sum of all its sides.
A triangle has 3 sides. The length of the 2 sides are given. The third side is x . Therefore,
perimeter = 7 + 7 + x
perimeter < 28 feet
Therefore,
7 + 7 + x < 28
14 + x < 28
subtract 14 from both sides
14 - 14 + x < 28 - 14
x < 14
Therefore, the possible value of x are positive integers that are less than 14.
