Answer:
Ok so first you would have to turn them into improper fractions which is
3 [tex]\frac{1}{2\\}[/tex] = [tex]\frac{7}{2}[/tex] and 4 [tex]\frac{2}{5}[/tex] = [tex]\frac{22}{5}[/tex]
So now that you have made them both improper fractions you have to find common denominators.
To find common denominators you must multiply both the numerator and the denominator by the same thing. Since your oposing fraction has a denominator of 5 you can know that a even number wont go in an odd number so take [tex]\frac{22}{5}[/tex] and mutiply both numbers by 2 and get [tex]\frac{44}{10}[/tex]. Then mutiply both numbers in [tex]\frac{7}{2}[/tex] by 5 to get a common denominator.
[tex]\frac{35}{10}[/tex]
[tex]\frac{35}{10} -[/tex] [tex]\frac{44}{10}[/tex] =35 - 44 = -9 so your answer is [tex]-\frac{9}{10}[/tex]
Step-by-step explanation:
For what values of k the relation R:{(k2 , 5), (3k, 6)} is not a function?
Answer:
[tex]k=0[/tex] and [tex]k=3[/tex].
Step-by-step explanation:
To this relation be a function, the horizontal coordinates can't be equal. So, let's find the value of [tex]k[/tex] that makes those coordinates equal.
[tex]k^{2}=3k\\ k^{2}-3k=0\\k(k-3)=0\\[/tex]
Using the null factor property, we have
[tex]k=0\\k-3=0 \implies k=3[/tex]
Therefore, the given relation is not a function when [tex]k=0[/tex] and [tex]k=3[/tex].
Solve the system of equations below.
5.1 – 2y=18
3.x+3y=15
Answer: y= -6.45 and y=5-x
Step-by-step explanation:
Subtract 5.1 from both sides.
-2y= 18-5.1
Simplify 18- 5.1 to 12.9
-2y=12.9
Divide both sides by -2
y= - 12.9/2
Simplify 12.9/2 to 6.45
y=-6.45
Factor out the common term 3.
3(x+y)=15
Divide both sides by 3.
x+y =15/3
Simplify 15/3 to 5.
x+y = 5
Sub. x from both sides
y= 5-x
Find the value of x in the diagram below. Show your work.
Answer:
x=35
Step-by-step explanation:
the litle square inside of the half circle means its the angle of 90
so just do like that:
90=x+(4x-85)
and u have the answer x=35
Arionna claims that since there are 3 feet in a yard, there are 9 cubic feet in a cubic yard. Which statement about her claim is true? Arionna is correct because there are 3 feet across the length of a cubic yard and 3 feet across the depth of a cubic yard. 3 times 3 = 9 Arionna is correct because there are 3 feet in a yard and there are 3 dimensions in a cubic yard: length, depth, and height. 3 times 3 = 9 Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion will remain constant. Arionna is incorrect. There are 27 cubic feet in a cubic yard because a cubic yard is a prism with dimensions 3 ft Times 3 ft Times 3 ft. A prism with those dimensions will take 27 cubes to fill it if each cube is a unit cube of 1 ft.

Here are the first five terms of a sequence.
3 8 17 30
47
Find an expression, in terms of n, for the nth term of this sequence.
Answer:
So the formula for the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero
Step-by-step explanation:
3 8 17 30 47
First term = 3
Second term = 8
Third term = 17
Fourth term = 30
Fifth term = 47
Second term - first term = 8-3=5
Third term - second term = 17-8= 9
Fourth term - third term = 30-17=13
Fifth term - fourth term = 47-30=17
So the AP is 5 9 13 17
We find out that the common difference is 9-5 = 4
The formula for nth term of the AP is
= a + nd
So the formula fir the sequence is
Second term =first term + (a+nd)
Third term = second term + (a+nd)
And so on
Where n start with zero

Complete question
Nguyen is decorating the room for her sister's baby shower party. She is wrapping
Vietnamese conical hats in baby prints tissue paper to decorate the tables and some
shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If
she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?
A) 4,176 in²
B) 8,975 in²
C) 10,580 in²
D) 36,267 in²
Answer:
C) 10,580 in²
Step-by-step explanation:
The question above is solved by finding the Total Surface area of the the conical hats.
We are given the following values for each hats
Diameter of 16 inches , radius of the hat = Diameter ÷ 2 = 16 ÷ 2 = 8 inches
Height of 9 inches.
The formula for the Total Surface Area of a cone = πr[ r + √(h² + r²)]
= π × 8 [ 8 + √(9² + 8²)]
= 503.7 square inches or 503.7 in²
So, for one hat she would be needing 503.7 square inches or 503.7 in² of Vietnamese tissues.
We are told in the question that she wants to wrap 21 conical hats. Hence,
If 1 conical hats is wrapped with 503.7 in² of Vietnamese tissues.
21 conical hats =
21 × 503.7 in² = 10,577.7 in²
Approximately = 10,580 in²
Therefore, to wrap 21 Vietnamese hats, Nguyen would need 10,580 in² of tissue paper.
1) The extent to which data points from a set of data differ from each other or from the true mean or average.
Answer:
measure of variability
Step-by-step explanation:
Measure of variability shows the extent in which data in a statically distribution differ from an average value as well as how they differ from each other. It shows how much the data falls from the center value (mean) showing the width of the distribution. The most used measures of variability are the range, interquartile range, variance, and standard deviation depending on the data to be measured.

answer my question and i will mark you as brainliest its that easy answer
Answer:
13 degrees
Step-by-step explanation:
85 and A are opposite hence equal so A = 85
98 and C are equal because they are corresponding angles hence C = 98
B and C are in a straight line so they add up to 180
B = 180-98 = 82
Finally, A and B and X add to 180 because they for a triangle
X+85+82 = 180
X= 13 degrees

5. Cameron found the volume of the cone below, but when he double-
checked his work, he got a different solution. Determine which solution
best represents the volume of the cone.
TRY #1
169.6 in 3
TRY #2
56.5 in 3
Answer:
Try 2 is correct
Step-by-step explanation:
See attachment for dimension of cone.
From the attached,
The diameter of the cone, d = 6 in
The height of the cone, h = 6 in
The volume of a cone is calculated as thus
Volume = ⅓πr²h
So, we need the value of r.
r represents radius and
r = ½d
r = ½ * 6
r = 3.
So,
Volume = ⅓πr²h becomes
Volume = ⅓ * π * 3² * 6
Volume = π * 3 * 6
Volume = π * 18
Volume = 18π
Take π as 3.14
So,
Volume = 18 * 3.14
Volume = 56.52 in³
Given that
Try 1 = 169.6 in³
Try 2 = 56.5 in³
We can conclude that Try 1 is incorrect and Try 2 is correct

Answer:
[tex]2(x+4)(x+2)[/tex]
Step-by-step explanation:
We can start with the observation that every coefficent in the quadratic [tex]2x^2 + 12x +16[/tex] is a multiple of 2. Factoring out the 2, our expression becomes [tex]2(x^2+6x+8)[/tex]. Let's focus on the second term, [tex]x^2+6x+8[/tex]. To factor this, we want to find two numbers that multiply to 8 and add to 6. 4 · 2 = 8 and 4 + 2 = 6, so we can use that fact to split the middle term and factor the quadratic completely:
[tex]x^2+6x+8\\=x^2+2x+4x+8\\=x(x+2)+4(x+2)\\=(x+4)(x+2)[/tex]
Putting that back with the 2 we factored out earlier, our fully factored function is
[tex]2(x+4)(x+2)[/tex]

Angles y and z are complimentary. If angle y is 18°, what is the measure of angle z?
18°
36°
72°
162°
Answer:
z = 72°
Step-by-step explanation:
Complimentary angles sum to 90° , thus
z + y = 180, that is
z + 18 = 90 ( subtract 18 from both sides )
z = 72°
So the right answer is 72 degree.
