Median = 56, option C#3
Median = 113, option C#4
A = 10, the minimum point#5
Q1 = 99.5, the median of the lower half of data, option CFind the missing term: (x+3)² = x² + 6x + _____
Answer:
9
Step-by-step explanation:
The formula for (a + b)^2 expands out to: a^2 + 2ab + b^2. In the case of this problem, a equals x and b equals 3. We can substitute to get:
(a + b)^2 = a^2 + 2ab + b^2
(x + 3)^2 = x^2 + 2(x)(3) + (3)^2
(x + 3)^2 = x^2 + 6x + 9
So, the missing term is 9.
Another way to do this is to multiply (x + 3)(x + 3) since it's the same thing:
(x + 3)(x + 3)
x^2 + 3x + 3x +9
x^2 + 6x + 9
By solving this way, you get the same answer.
Answer:
It would be 9.
Step-by-step explanation:
To do this, lets expand the equation (x+3)^2 by turning it into:
(x+3)(x+3)
Now, lets try something called the FOIL method. This is where all of the terms of the equation are multiplied in the order:
1) First
2) Outer
3) Inner
4) Last
So in (x+3)(x+3), each of the first parts of each parentheses box are x's, and x times itself equals x^2 so:
x^2 + ? + ? so far.
Next, with the Outer & Inner parts, they would be x * 3 and 3 * x. With this, you would get 3x and 3x. These can be added to get 6x, the middle part of the equation.
x^2 + 6x + ? so far.
Lastly, for the answer. Time to do the last part of each parentheses box, you would get 3 * 3, which gives you 9.
x^2 + 6x + 9.

36/9+2/9 fraction adding!!!
Answer: 38/9
Step-by-step explanation: Because the fractions presented already have common denominators, the only thing you need to do in order to solve the problem is add the numerators. 36+2= 38, and you keep your denominator the same when adding fractions (when they are the same).

Lori had $126.89 in her bank account. She deposited $21.49 into it and then wrote a check for her car repairs for $156.61.
What was the ending balance in her account?
O -$51.21
O $8.23
O $8.23
O $51.21
What is the answer?
Answer:
-8.23
Step-by-step explanation:
If Lori had $126.89 in her bank account and she deposited $21.49, she would be adding that to the amount of money in her bank account.
126.89+21.59= 148.48
Then subtract the amount of money the repairs costed.
148.48 - 156.61 = -8.23
Therefore Lori would have a balance of -$8.23.
Answer:
Lori had $126.89 in her bank account.
She deposited $21.49 into it and then wrote a check for her car repairs for $156.61
126.89+ 21.49=148.38
148.38-156.61=−8.23
the answer is -8.23

Answer:
(-2.5, 1) and (0.5, 5)
Step-by-step explanation:
The main idea is to divide the line into four segments.
so you find the midpoint between (-4, -1) and (2, 7), which is (-1, 3).
then you find the midpoint again between (-4, -1) (-1, 3) and (2, 7) (-1, 3), which is (-2.5, 1) and (0.5, 5).
An angle measures 58° less than the measure of a complementary angle. What is the measure of each angle?
Answer: 74 degrees and 16 degrees
Step-by-step explanation:
A pair of complementary angles add up to 90 degrees.
If we know that one of the two angles is 58 degrees less than the other, we can solve the algebraic equation: x + (x-58) = 90, where (x) is the measure of the one angle, and (x-58) is the measure of the other angle.
x + x-58 = 90 is the same as 2x -58 = 90.
Adding 58 to both sides gives 2x = 148,
and dividing both sides by two gives x = 74.
We now know that one angle is 74 degrees, and the other angle is (74-58) degrees. This gives two angles of 74 and 16 degrees. They both add up to 90 degrees, so they are complementary angles.
True or false
You always have to use x and y as your variables when writing
equations for word problems.
Answer:
false
Step-by-step explanation:
you can use whatever letters you want to represent things. x and y make sense that you would use just them for graphing, but if it is a word problem you could have like c for cost or t for time or something

Answer:
X is about 58.41 degrees
Step-by-step explanation:
For this problem, lets use sine, since we have the opposite angle from x and we have the hypotenuse.
Therefore, with the equation for sine, we would get
sin(x) = 23/27
sin(x) = 0.851
Now, since we're solving for an angle, inverse it by adding a -1 to move over the sin.
x = sin-1 23/27
Last, use a calculator to get the answer.
X is about 58.41 degrees

1 Escritura unida
Según la NGLE se unen las palabras que se interpretan como una unidad y en las que, por tanto, la marca de plural solo afecta al último elemento:[1]
el bajorrelieve, los bajorrelieves
la mediapunta, las mediapuntas
En un buen número de casos, el primer elemento puede seguir teniendo individualidad para parte de los hablantes y admitir la marca del plural. La Gramática admite algunos de esos casos, de modo que las dos formas son posibles, que se escribirán unidas o separadas según se dé ese plural o no:
el puercoespín, los puercoespines; el puerco espín, los puercos espines
el arcoíris, los arcoíris; el arco iris, los arcos iris
el medioambiente, los medioambientes; el medio ambiente, los medios ambientes.
el pavorreal, los pavorreales; el pavo real, los pavos reales
La Gramática prefiere, como norma general, la forma en una palabra.

Mike saves $42 a week for 7 weeks. During his 8-day vacation, he plans to spend $8.25 each day for snacks. Which expression shows how much money he will have left?
Answer:
($42 × 7) - ($8.25 × 8)
Step-by-step explanation:
Given that
Mike saves $42 a week for 7 weeks
And, his 8 day vacation, he plans to spend $8.25 each day
We need to find out the expression of how much he would have left
So,
Since the amount $42 is for a week
So for 7 weeks, it would be
= $42 × 7
And, he spends $8.25 each day,
And, for 8 days, it would be
= $8.25 × 8
So, the expression is
= ($42 × 7) - ($8.25 × 8)
Colette and Tycen made a quarts of lemonade to sell by the cup. Tycen's mother made 5 more cups of lemonade for them to sell. The
equation below can be used to find the number of cups of lemonade, c, they can sell when they make a quarts of lemonade.
C = 40 + 5
What is the greatest number of cups of lemonade Colette and Tycen can sell when q = 3?
Answer:
12 cups
Step-by-step explanation:
1 quart is 4 cups, so 4 x 3= 12 and 1 x 3 = 3.. Good Luck!
Find the area inside the 26m square and outside the circle. Use 3.14 for π. A circle is fully inside a square with sides of length 26 meters, such that the circle touches the center of each side of the square.
Answer:
A(b) = 145,34 m²
Step-by-step explanation:
Area of the square of side l = 26 m A(s) = l² A(s) = (26)²
A(s) = 676 m²
Areaof the circle of radius r = 13 A(c) = π*(r)² A(c) = π*(13)²
A(c) = 169*π m²
Then the area outside the circle and inside the square A(b), is the difference between the area of the square minus the area of the circle, that is:
A(b) = A(s) - A(c) = 676 - 169*π m²
A(b) = 676 - 530,66 m²
A(b) = 145,34 m²
