18 is 4.5 times a number.
The value of x is equal to 4, that is 4.5 times 18 is 4
Given that the expression:
18 is equal to 4.5 times a number.
Assume that the number be x.
To find the number that is 4.5 times 18, we can set up the following equation:
4.5 × x = 18
Now, to find the value of x, divide both sides of the equation by 4.5:
4.5 × x / 4.5 = 18 / 4.5
x = 18 / 4.5
x = 4
So, the number that is 4.5 times 18 is 4.

[tex]y \to Gallons[/tex]
See attachment for complete question
Required
Time to fill the tube with 46.2 gallons
The attached table is a represents a direct proportional relationship between x and y.
This relationship is:
[tex]y = kx[/tex]
Where k is the constant of proportionality.
When (x,y) = (1,16.5), we have:
[tex]16.5 = k*1[/tex]
[tex]16.5 = k[/tex]
[tex]k=16.5[/tex]
So, we have:
[tex]y = kx[/tex]
[tex]y = 16.5x[/tex]
To calculate the required time to fill 46.2 gallons, we make x the subject
[tex]x = \frac{y}{16.5}[/tex]
Where
[tex]y =46.2[/tex]
[tex]x = \frac{46.2}{16.5}[/tex]

B.5/12 of an hour per book
C. 2 and 2/5 books per hour
D.2 and 2/5 hours per book
Answer:

David has a gift that he needs to wrap. He is trying to decide if he has enough Avengers wrapping paper or if he will have to use the plain blue
ones he has. The gift is 18 inches by 2 feet by 9 inches, rectangular shape. If he has a piece of Avengers wrapping paper that is 3.5 feet by 3
feet, is it enough to cover the present?
Answer:
no, it isn't enough to cover the present
Step-by-step explanation:
first, find the volume of the gift in feet
18*9=162 inches
162/12= 13.5 feet
13.5*2= 27 feet
then, the wrapping paper
3.5*3= 10.5 feet
compare them
27>10.5 meaning there isn't enough wrapping paper

Find the lateral surface area of the can of mandarin oranges. Round your answer to the nearest tenth. Radius: 4cm, Height: 11cm
Answer:
276.3cm²
Step-by-step explanation:
The lateral surface area is the area of all the sides of a 3-dimensional object excluding its base and top.
A can is in the shape of a cylinder
Lateral surface area of a cylinder = 2πrh
π = pi = 3.14
h = height = 11
r = radius = 4
2 x 3.14 x 4 x 11 = 276.32 cm²
to the nearest tenth = 276.3 cm²
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Can someone help me? And no, I don’t just want the answer. I literally need to know how to do it pls
Answer:
36
Step-by-step explanation:
The angle b is a right angle which is divided into 2. So, each angle would measure 45 degree. (90 / 2 = 45)
tan 45 = 1
\AD\ = 100 - 64 = 36
to find x , remember SOCAHTOA
tan would be used because we have the vale of the opposite angle and we want to find the value of the adjacent angle
Tan 45 = opposite / adjacent
1 = 36/x
x = 36
which of the following is the value of x?
9514 1404 393
Answer:
x = 20°
Step-by-step explanation:
Assuming parallel lines, the two angles marked with measures are complementary to each other.
45° +(5x +35°) = 180°
5x = 100° . . . . . . . . . . . . subtract 80° from both sides
x = 20° . . . . . . . . divide by 5

Comment on the geometry
Where a transversal crosses parallel lines, all of the obtuse angles are congruent, and all of the acute angles are congruent. Of course, the acute angles and obtuse angles are linear pairs, hence supplementary. (The only time this won't apply is when all angles are right angles.)
No lines are marked as parallel here, nor does any part of this problem statement say there are parallel lines. So, we cannot find the value of x if we're going strictly by what is shown in the diagram. In the absence of any information, we can only say that the angle marked with an x-expression must be between 0° and 180°.
0 ≤ 5x +35 ≤ 180 ... -35 ≤ 5x ≤ 145 ... -7 ≤ x ≤ 29.

Help find the missing side show your work and get brainly
Answer:
[tex]\sqrt{32}[/tex]
Step-by-step explanation:
Pythagorean - [tex]a^2+b^2=c^2[/tex]
where a and b = legs and c = hypotenuse
For the following problem we are given the hypotenuse ( [tex]\sqrt{84}[/tex] ) and a leg ( [tex]\sqrt{52}[/tex] ) and we need to find the missing side length ( which also happens to be a leg.)
That being said we can find the missing leg by plugging in what we are given into [tex]a^2+b^2=c^2[/tex] ( let a = missing side length )
[tex]a^2+\sqrt{52}^2=\sqrt{84} ^2\\\sqrt{52} ^2=52\\\sqrt{84}^2 =84\\a^2+52=84[/tex]
* subtract 52 from each side
84 - 52 = 32
52 - 52 cancels out
we now have a² = 32
step 2 take the square root of each side
[tex]\sqrt{a^2} =a\\\sqrt{32} =\sqrt{32}[/tex]
Assuming that we are supposed to leave the answer in radical form the answer would be sqrt 32
Answer:
7 in.
Step-by-step explanation:
Let x = the length of the missing side
[tex]x^{2} + \sqrt{32} ^{2} = \sqrt{81} ^{2}[/tex]
[tex]x^{2} +32 = 81[/tex]
[tex]x^{2} = 49\\[/tex]
x = 7 in.
How do I solve this I need help and if it’s not too much trouble can you help me understand which system to use. (Btw it’s trigonometry)
Answer:
[tex]x = 11.4[/tex]
Step-by-step explanation:
So there are ways to find a missing side of a triangle.
Pythagorean TheoremLaw of SinesLaw of CosinesSine,Tangent, or Cosine Function.I'll explain when we use them,
We use pythagorean theorem if we have a right angle and know at least two sides of a triangle. Since we dont know two sides, we are not going to use that.We use law of sines if we know a given angle and a side opposite of that angle and a side or angle opposite of the angle or side we are trying to findIf we apply the triangle interior theorem, we can use law of sines. Since 11 and 44 degrees are opposite sides, and x and the missing angle which is 46 is opposite side and angle as well.We use law of Cosines if we know two sides and a angle between them. We have a missing side so we cant use law of Cosines.Since we are trying to find side measures, sometimes it isn't advised to use SOHCAHTOA.So let use law of sines.[tex] \frac{11}{ \sin(44) } = \frac{x}{ \sin(46) } [/tex]
[tex] \frac{11}{ \sin(44) } \times \sin(46) = x [/tex]
