Answer:
okay so Y can be 6
and x can be 3
Step-by-step explanation:
so first 2*x=y
the most most likely answer will be y is 6 and x is 3 because
5*3=15
y=6
15-6=9
so x is 3 and y is 6
Find the distance between the pair of points. (4,1) and (9,6)
Answer:
5√2 or 7.07 units
Step-by-step explanation:
To find the distance between two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]
Plug in the given values of (4,1) and (9,6)
d = √[(x₂ - x₁)² + (y₂ - y₁)²]
d = √[(9 - 4)² + (6 - 1)²]
Simplify the parentheses.
d = √[(5)² + (5)²]
Simplify the exponents.
d = √[25 + 25]
Add.
d = √[50]
Evaluate the radical.
5√2 or 7.07
Round the decimal.
5√2 or 7.07 units

In a poll to pick the name of a new planet discovered in a distant solar system, a total of 963 scientists voted. There were four names to pick from. The winning name exceeded the other names by 53, 79, and 105 votes, respectively. How many scientists voted for the name which came fourth in the poll?
Answer:
195
Step-by-step explanation:
Let wining name have, x votes
1st = x
2nd = x - 53
3rd = x - 79
4th = x - 105
x + (x - 53) + (x - 79) + (x - 105) = 963
x + x - 53 + x - 79 + x - 105 = 963
4x - 237 = 963
4x = 963 + 237
4x = 1200
x = 1200 / 4
x = 300
4th = x - 105
x - 105 = 300 - 105 = 195

so i think it would be 17 as 5 is equivlent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since i think ur school rounds that percentage it would 17 red shirts
The results are in the table of the 250 total T-shirts about should be red 17.
We have given that,
Mr. torres ordered 250 School t-shirts to sell in a school store the t-shirts come in blue-gray or red to know how many of each color to order Mr. Torres polled a random sample of students. the results are in the table.
What is the random sample?
A simple random sample is a subset of a statistical population in which each member of the subset has an equal probability of being chosen.
So I think it would be 17 as 5 is equivalent to 8.33 percent of 60 which is the total amount of kids and 8.33 percent of 250 is 20 but since I think your school grounds that percentage it would be 17 red shirts.

Where is the function increasing? A) 1 < x < ∞ B) 3 < x < ∞ C) -∞ < x < 1 D) -∞ < x < 3
please hurry i have 5mins
Answer: I think its A
Step-by-step explanation:
The given function is increasing from 1 to ∞. Therefore, option A is the correct answer.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
From the given graph, the vertex is (1, -2)
For a function y = f(x), if the value of y increases on increasing the value of x, then the function is an increasing function.
Here, the function is increasing from 1 to infinity.
Therefore, option A is the correct answer.

explain rounding up numbers i dont mean only examples but definitions too
Answer:
Rounding up numbers means to make a number with many numerical values or digits into a more simpler way.
Step-by-step explanation:
In order to round up a number you have to look to the digit next to it and if its greater then five it rounds up, if it's less then five it stays the same. If the number only has one digit then you have to look at that number and round up by seeing if its greater than or less than five.
Examples:
[tex]7[/tex]
[tex]7>5[/tex]
[tex]7=10[/tex]
7 rounded up equals 10 because 7 is more near 10 then it is to one.
Round the number 12,371 to the nearest thousand.
This means to find the thousands place value (two) check the number next to the thousands place value (hundreds or three) and check to see if that number is greater then five or not.
[tex]12,371[/tex]
[tex]3 <5[/tex]
[tex]=12,000[/tex]
Therefore the 12,371 rounded to the nearest thousand is "twelve-thousand" and that's because three is not greater then or equal to five.

If ε = {whole numbers less than 50 but greater than 20} and X = {perfect squares}, Y = {factors of 12}, Z = {prime numbers}; find the following:
a) X ∪ Y
b) X ∩ Y
c) X ′
d) X′ ∩ Y ∩ Z
Answer:
A. X∪Y = {25, 36, 49}
B. X∩Y = ∅ i.e empty set
C. X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
D. X′∩Y∩Z = ∅
Step-by-step explanation:
We'll begin by determining the universal set (ε), set X, set Y and set Z.
This can be obtained as follow:
ε = {whole numbers less than 50 but greater than 20}
ε = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49}
X = {perfect squares}
X = {25, 36, 49}
Y = {factors of 12}
Y = ∅ i.e empty
Z = {prime numbers}
Z = {23, 29, 31, 37, 41, 43, 47}
A. Determination of X∪Y
X = {25, 36, 49}
Y = ∅
X∪Y =?
X∪Y => combination of elements in set X and Y without repeating any element in both X and Y.
X∪Y = {25, 36, 49}
B. Determination of X∩Y
X = {25, 36, 49}
Y = ∅
X∩Y =?
X∩Y => elements common to both set X and Y
X∩Y = ∅ i.e empty
C. Determination of X′
ε = {21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49}
X = {25, 36, 49}
X' =?
X' => elements in the universal set but not found in set X.
X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
D. Determination of X′∩Y∩Z
X' = {21, 22, 23, 24, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48}
Y = ∅
Z = {23, 29, 31, 37, 41, 43, 47}
X′∩Y∩Z =?
X′∩Y∩Z => elements common to set X', Y and Z
X′∩Y∩Z = ∅

How many cubic meters of material are there in conical pile of dirt that has radius 9 meters and height 6 meters?Use 3.14 for pi
Answer:
V = 226.08 m³
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(πr²)(h).
In this case, r = 6 m and h = 6 m. Thus, the volume of this conical pile is
V = (1/3)(3.14)(6 m)²(6 m), or
V = 226.08 m³

The area of a rectangular dance floor is 8 1/4
square yards, and its width is 3 1/2 yards. What is the patio's length in yards
A 54
B 2
C 4:
D 5
Answer:
2 5/14 yards
Step-by-step explanation:
Area of the rectangular floor = Length * Width
Given
Area = 8 1/4 square yards
width = 3
1/2 yards
Required
Length
Length = Area/width
Length = (8 1/4)/(3 1/2)
Length = 33/4 ÷ 7/2
Length = 33/4 * 2/7
Length = 33/14
length = 2 5/14 yards
This gives the required length

A jar had 88 coins. 1/3 of the coins were silver. How many coins were gold?
Answer:
There are 66 gold coins in the jar
Step-by-step explanation:
Let the number of silver coins = X
Then the number of gold coins = 3X (as there are 1/3 number of silver coins as gold)
Total coins =88
Total coins = silver coins + gold coins
Total coins = X + 3X = 88
Total coins = 4X = 88
X = 88/4
X = 22
No. Of silver coins = 22
No. Of gold coins = 3X = 3×22
No. Of gold coins = 3X= 66
Check
Total coins = 3X + X = 88
66+22 = 88
88 = 88
Hope it helps...
Have a great day :P
Answer:
Hello There!!
Step-by-step explanation:
Let the number of silver coins be x and gold coins be 3x which add up to 4x. Make an expression and add 88 with 4x so 4x=88
x=22(88÷4).
So x=22[silver coins]
3x=66(22×3) [gold coins]
hope this helps,have a great day!!
