How do you add 11/11 + 23/45? And what is the answer? Explain how you got that answer
Answer:
90
Step-by-step explanation:
first you do 11 + 11 =22
23+45=68
now im postitive you add 68 and 22 and get you final answer which is ...
90
Answer:
1 23/45
Step-by-step explanation:
Start by multiplying numerators and denominators to get the LCD in all fraction denominators
=11×45/11×45+23×11/45×11
Then rewriting the equation with the equivalent fractions
=495/495+253/495
With like denominators we can operate on just the numerators
=495+253/495
=748/495
Simplifying the answer
=68/45
=68/45
=1 23/45

so he had 5 goats and 19 carrots
19/5=3.8 which mean 3 and 4 left
Find the value of c that makes the trinomial a perfect square: x^2– 40x + c
Answer:
c=400
Step-by-step explanation:
Use the perfect square formula:
ax^2+bx+c=0
x^2-40x+c=0
bring c to the other side
x^2-40x+___=-c
divide -40 by 2 then square it; 400
add 400 to each side
c=400
(x-20)(x-20)
The value of c that makes the trinomial a perfect square x²– 40x + c is 400.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
We have to find the value of c that makes the trinomial a perfect square: x²– 40x + c
Lets use the perfect square formula:
ax²+bx+c=0
The given equation is given below.
x²-40x+c=0
Take the c term to the right hand side
x²-40x=-c
x²-40x+400=-c+400
c=400
Hence, the value of c that makes the trinomial a perfect square x²– 40x + c is 400.

Freddie swam 5/7 laps on Monday, Tuesday, and Wednesday. 1/4 laps on Thursday and Friday. How many laps did he swim in total?
Answer: 27/28 or 0.9642857
Step-by-step explanation:
5/7 + 1/4 = 5 · 4/7 · 4 + 1 · 7/4 · 7 = 20/28 + 7/28 = 20 + 7/28 = 27/28
The table below shows the number of minutes a household phone is used daily based on the number of household members.
Which equation best models this set of data?
A. P = -20.2x^2 - 1.3
B. P= -20.2x - 1.3
C. P= 20.2X^2 + 1.3
D. P= 20.2x + 1.3
I'm pretty sure the answer would be D) P = 20.2x + 1.3 but the answer should be P = 19.2x + 1.3, but it isn't listed so it would be D
Rico's dog weighs 64 pounds.
The dog is 3 times as heavy as he was when he was 6 months old.
Write an equation that can be used to find the dog's weight, w, when he was 6
months old.
The equation that can be used to represent the weight of the dog when he was 6 months old is 64/x.
What is the equation that can be used to represent the weight of the dog when he was 6 months old?The equation that can be used to represent the dog's current weight is: 64 = 3x
Where x represents the weight of the dog when he was 6 months old
In order to determine the value of x, divide both sides of the equation by 3
x = 64/x

Write an EQUATION with an undefined slope:
Answer:
Example of an equation with an undefined slope: x = 2
Step-by-step explanation:
DefinitionsThe standard form of linear equations with an undefined slope is x = a, whose graph represents a vertical line. The value of a in the standard form is the x-intercept, (a, 0).
The slope is the ratio of the vertical change in y-values to the horizontal change in x-values.
[tex]\displaystyle\mathsf{Slope(m) =\:\frac{\triangle y}{\triangle x}\:=\frac{y_2 - y_1}{x_2 - x_1}}[/tex]
The slope of a vertical line is undefined because if we were to solve its slope, the denominator will be zero. As we know, division by zero is an undefined operation.
Example:For example, suppose that we have the following points (2, 5) (2, 10).
Let (x₁, y₁) = (2, 5)
(x₂, y₂) = (2, 10)
Substitute these values into the slope formula:
[tex]\displaystyle\mathsf{Slope(m) =\:\frac{\triangle y}{\triangle x}\:=\frac{y_2 - y_1}{x_2 - x_1}\:=\:\frac{10\:-\:5}{2\:-\:2}\:=\frac{5}{0}}[/tex]
Dividing the numerator, 5, by the denominator, 0, will have an undefined quotient.
Thus, the equation of the vertical line will be: x = 2, where a = 2.

Sarah rolls 2 fair dice and adds the results from each.
Work out the probability of getting a total of 2.
Answer:
1/36.
Step-by-step explanation:
She gets 1 on the first dice and 1 on the second.
This is the only way Sarah can get a sum of 2.
The total possible outcomes is 6*6 = 36.
So the required probability is 1/36.
Please I need Help!!! Solve this equation by factoring by grouping x^2-4x=12. All work must be shown and no other method will be accepted.
x² - 4x = 12
x² - 4x - 12 = 0
x² + (2x - 6x) - 12 = 0
x² + 2x - 6x - 12 = 0
x (x + 2) - 6 (x + 2) = 0
(x - 6) (x + 2) = 0
Then the solutions are x = 6 or x = -2.

Answer:
48. 95,400 mL
50a. 331 yds.
50b. 11,916 in.
Step-by-step explanation:
Some helpful conversions can solve this for you :)
1 liter = 1000 mL
1 yard = 3 feet
1 feet = 12 inches
Now we get started!
48. We have 95.4 Liters, multiply by 1000 because 1000 mL per Liter. Therefore it's 95,400.
50
a. 3 feet per yard, so 993 feet divided by 3 is 331 yards.
b. 12 inches per foot, so 993 feet multiplied by 12 is 11,916

Which algebraic expression represents the
following situation: Six fewer seashells than
the total number of seashells in p packages,
each of which has five seashells?
Is it c
Answer:
Yes, it is c
Step-by-step explanation:
Because there are 5 seashells in p packages, you can do 5p to represent the total. There are 6 fewer sea shells, so it would be 5p-6 to represent the new situation.
Based on the information given, the equation to represent the situation is 5p - 6.
The information given is that there are six fewer seashells than the total number of seashells in p packages, each of which has five seashells.
Therefore, the equation will be:
= (5 × p) - 6
= 5p - 6.
