5.1 – 2y=18
3.x+3y=15
Answers
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

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.
Plz help!!! Calvin is filling the pool in his backyard with water. If the pool is in the shape of a cylinder with a diameter of 12ft and a height of 5 ft, how much water is needed to fill a 3/4 of the pool?
Answers
Answer:
424.1175
Step-by-step explanation:
Volume of the total pool = π[tex]r^{2}[/tex]h
= π x [tex]6^{2}[/tex] x 5
= 565.49
needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49
= 424.1175
Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.
Definition of volumeVolume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.
Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).
Volume of a cylinderIn the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.
Amount of water neededIn first place, you must know that the length of the radius is half the length of the diameter.
On the other side, it is needed to fill a 3/4 of the pool.
Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:
amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft
Solving:
amount of water=(3/4)×π×(6 ft)²× 5 ft
amount of water= 135π ft³
Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

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.
Answers
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

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]

What is the value of x?
Answers
Answer: x = 27
Step-by-step explanation:
The angles (4x + 7) and 5(x - 4) are opposite angles formed by intersecting lines.
When intersecting lines form two sets of opposing angles, both pairs are equal in angle measure.
As such, the angles (4x + 7) and 5(x - 4) are equal. Knowing this, you can solve for x by setting the angles equal to each other in an equation:
[tex](4x + 7) = 5(x - 4)\\\\4x + 7 = 5x - 20\\\\27 = x[/tex]
X = 27.

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.

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

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]
