Which number is an integer?
Answer:
Step-by-step explanation:
Can you please specify on that question
Answer:
Integers are numbers that include the negatives, zero and positives.
Step-by-step explanation:
If you ever get confused there's a big circle chart to help you remember look for it online!! What I use to remember is visualizing a number line!
First is the real numbers, so the numbers we were taught since we were little like 1, 2 ,3, 4, 5, 6 and so on. So that's the first part of the number line.
Next is the whole numbers so you just add a zero to that number line. Whole numbers is just all of the real numbers + the number zero.
Then it's the integers so you add the left side of that number line. Integers are real numbers, whole numbers, and negatives. So basically on the number line it's the negatives , zero, and the positives.
Last it's the radicals so all parts of a number like fractions and decimals. So you can add .5 in between the numbers of that numberline.
I hope this strategy helped and if it didn't here's that circle chart!!
I really hope this did help tho!!

You measure an obtuse angle on a protractor. If neither of the rays of the angle points at 0° or 180°, where could they point? Give the two points using degrees and explain why you chose those points.
Answer:
Any point greater Than 0 and less than 180°
Step-by-step explanation:
Obtuse angle measures are angles which measures angles in the range between 0° and 180°. Angles which lies between these range are called obtuse angles. Hence, from the question, if the ray of points measured does not point to 0° or 180°; then, the ray of angle points could have pointed to any angle between greater Than Zero less than 180.
Hence the points could 10 and 120 or any other values which meets the obtuse angle condition.
Answer:
173-degree angle (any angle larger than 90 degrees is obtuse and why are there favorite numbers all of a sudden????)
145-degree angle (there really is no reason to choose 2 certain numbers)
Step-by-step explanation:
any angle larger than 90 degrees is obtuse, so there you go my children.

Write the function in the form f(x) = (x − k)q(x) + r for the given value of k. F(x) = x3 − x2 − 18x + 19, k = 4 f(x) = Demonstrate that f(k) = r. F(4) =
Solution :
Given :
[tex]$f(x)=x^3-x^2-18x+19$[/tex]
By using the remainder theorem, if f(x) is divided by (x-k) and the remainder is 'r', then
[tex]$f(x)=(x-k)q(x)+r$[/tex]
Here, k = 4
Therefore, divide the f(x) with (x - 4) to find the q(x) and r.

A. 9
B. 362,880
C. 126
D. 3024
Answer:
3024
Step-by-step explanation:
3024
Option (D) 3024 is the permutation value is the correct answer.
What is a permutation?A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.
For the given situation,
The value of 9P4
The formula to find permutation is
[tex]nP_{r}=\frac{n!}{(n-r)!}[/tex]
Here, n = 9 and r = 4
⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]
⇒ [tex]\frac{9!}{5!}[/tex]
⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]
⇒ [tex](6)(7)(8)(9)[/tex]
⇒ [tex]3024[/tex]
Hence we can conclude that option (D) 3024 is the permutation value is the correct answer.

Can u find the value of the x.
Answer:x=8
Step-by-step explanation:
x²-3x=-3x+64
- Add 3x to both sides
x²-3x+3x=-3x+3x+64
= x²=64
- Square both sides
√x²=√64
x=±8
- Since the question is asking for the positive value of x, the answer is 8.
The town provides free lemonade for people at the parade. Marty determines how much lemonade to order. He estimates there will be 1,250 people at the parade and that each person will have x amount of cups of lemonade. He uses his estimate and also orders an additional 150 cups of lemonade. He determines that he needs an amount of lemonade equal to 1,087.5 cups. Write an equation that can be used to determine the value of x. PLEASE HELP ME. I'VE ASKED A LEAF BLOWER.
Answer:
x = 1,087.5 /1250
Step-by-step explanation:
If there are 1250 at the parade and each person needs x amount of cups
total amount of cups needed = 1250x
total cups needed = 1,087.5
therefore - 1250x = 1087.5
x = 1087.5 / 1250

Find the area of this trapezoid. Area = _______ square units. Round to the nearest whole number.
Answer:
119 square units
Step-by-step explanation:
To find the area of a trapezoid, use this formula: (a+b)/2 * h
Substitute 24, 10, and 7 for a, b, and h, respectively.
((24 + 10)/2) * 7
Step 1: Add 24 and 10 to get 34.
(34/2) * 7
Step 2: Divide 34 by 2 to get 17.
17 * 7
Step 3: Multiply 17 by 7 to get 119
