Write 3 1/2 hours : 36min as a ratio in its simplest form
Answer:
Step-by-step explanation:
you can re-write 3 1/2 hours into minutes.
1 hr = 60 minutes,
Therefore:
3 1/2 hours = 3.5 times 60 = 210 minutes
So now we have the ratio:
3 1/2 hours : 36 minutes
210 minutes : 36 minutes
Both numbers can be divided by 6
210/6 = 35 and 36/6 = 6
So now we can re-write the ratio as :
35 : 6

please help!! a circular garden has a diameter of 16 yards. what is the area of the garden. use 3.14 for pi.
A. 50.24 yd2
B. 100.48 yd2
C. 200.96 yd2
D. 803.84 yd2
Answer:
C. 200.96 yd²
Step-by-step explanation:
diameter = 16 yd
radius = diameter/2 = 16 yd / 2 = 8 yd
area = πr²
area = 3.14 × (8 yd)²
area = 200.96 yd²

ax-bx=3;x
I need help :
Answer:
x = [tex]\frac{3}{a-b}[/tex]
Step-by-step explanation:
Given
ax - bx = 3 ← factor out x from each term on the left side
x(a - b) = 3 ← divide both sides by (a - b)
x = [tex]\frac{3}{a-b}[/tex]
2x+5=12
Show me the working out
Answer:
[tex]\sf{x=\dfrac{7}{2}=3.5 }[/tex]
Step-by-step explanation:
It is necessary to isolate the term of x from both sides in order to solve this problem.
First, subtract by 5 from both sides.
2x+5=12
[tex]\sf{2x+5-5=12-5}[/tex]
Solve.
[tex]\sf{12-5=7}[/tex]
2x=7
Divide by 2 from both sides.
2x/2=7/2
Solve.
Dividing is another option.
7/2=3.5
So, the final answer is 7/2=3.5.
I hope this helps you! Please let me know if my answer is wrong.

Drag each day to the correct location on the tree drag each estimated measurement next to the correct she not all shapes and measurements will be used.
A tree from a forest with a height of 30 feet is shown below the bottom branches are about 4 feet from the ground and are 10 feet long from left to right.the tree trunk is about 2 feet wide.
what are the appropriate shapes to model the trunk of the tree and the rest of the tree?what are the approximate surface areas of each of the two shapes?
Answer: cone Cylinder
Surface area is 402ft2 and 69ft2
Step-by-step explanation:
I got the answer right
The appropriate shape to model trunk is cylinder, rest of the tree is cone and surface area of trunk is 25.12 [tex]feet^{2}[/tex]and surface area of rest of the tree is 415.58 [tex]feet^{2}[/tex].
What is surface area?It is the space occupied by a two dimensional surface. The area occupied by a three dimensional object by its outer surface area.
How to calculate surface area?The upper part of the tree is similar to the cone and the trunk is of cylindrical shape. So the appropriate shape used to model the entire is cone above the cylinder.
We have been given the height of entire tree=30 feet,
Width of upper part=10 feet.
Height of trunk=4 feet
Width of tree means diameter of upper part or cone. Height of cone means height of cylinder, width of trunk means diameter of cone.
So, The radius of cone ie 5 feer,radius of cylinder is 1 feet, height of cone be 30-4=26 feet.
Surface area of cone is πrl where l is slant height of cone which is equal to [tex]\sqrt{r^{2} +h^{2} }[/tex]
l=[tex]\sqrt{5^{2} +26^{2} }[/tex]
=[tex]\sqrt{701}[/tex]
=26.47 feet.
Surface area of cone=π*5*26.47
=3.14*5.26*26.47
=415,28 [tex]feet^{2}[/tex]
Surface area of cylinder=2πrh
=2π*4*1
=2*3.14*4
=25.12 [tex]feet^{2}[/tex]
Hence cone and cylinder of surface area 415.28 [tex]feet^{2}[/tex] and 25.12 [tex]feet^{2}[/tex] can be used to model out tree.

7. a. dilate point c using center d and scale factor 3/4
b. dilate segment ab using center d and scale factor 1/2.
The dilations will give the relations:
C'D = (3/4)CD and A'B' = (1/2)AB
And a sketch of the graph can be seen at the end.
How to dilate C?First, we want to dilate point C using D as the center of dilation with a scale factor = 3/4.
This only means that we will have the new point C', such that:
C'D = (3/4)*CD
Where CD is the distance between points C and D
b) Similarly, we will dilate the whole segment AB into the segment A'B', such that:
A'B' = (1/2)AB.
It is hard to give the exact graph when we don't know the coordinates of the points, but the graph should look something like the one you can see below.

If the area of a rectangle is 12mn^2 and the width is 3m^2n, what would be the length of the rectangle, given that length is found by dividing area by length?
Let's see
Area=Length×Breadth[tex]\\ \rm\rightarrowtail 3m^2n(L)=12mn^2[/tex]
[tex]\\ \rm\rightarrowtail mL=4n[/tex]
[tex]\\ \rm\rightarrowtail L=4n/m[/tex]
Answer:
[tex]\sf length=\dfrac{4n}{m}[/tex]
Step-by-step explanation:
Area of a rectangle = width × length
Given:
[tex]\sf area=12mn^2[/tex][tex]\sf width=3m^2n[/tex]Substituting the given expressions into the equation:
[tex]\sf \implies 12mn^2=3m^2n \times length[/tex]
[tex]\sf \implies length=\dfrac{12mn^2}{3m^2n}[/tex]
Factor 12 to 3 · 4:
[tex]\sf \implies length=\dfrac{3 \cdot 4mn^2}{3m^2n}[/tex]
Cancel the common factor of 3:
[tex]\sf \implies length=\dfrac{4mn^2}{m^2n}[/tex]
Simplify [tex]\sf \dfrac{n^2}{n}=n[/tex] :
[tex]\sf \implies length=\dfrac{4mn}{m^2}[/tex]
Simplify [tex]\sf \dfrac{m}{m^2}=\dfrac{1}{m}[/tex] :
[tex]\sf \implies length=\dfrac{4n}{m}[/tex]
Solve each system of equations 2a+b+c=0 2b+c+a=-4 2c+a+b+4
Answer:
(a, b, c) = (0, -4, 4)
Step-by-step explanation:
Any of a variety of calculators, spreadsheets, or web sites can solve these equations for you. A calculator result is attached. It shows the solution to be ...
(a, b, c) = (0, -4, 4)
__
If you'd like to solve the system by hand, here's one way:
Add the three equations together:
(2a +b +c) +(2b +c +a) +(2c +a +b) = (0) +(-4) +(4)
4a +4b +4c = 0 . . . . simplify
a +b +c = 0 . . . . . divide by 4
Substitute this into each of the other equations:
a +(a +b +c) = 0 ⇒ a +0 = 0 ⇒ a = 0
b +(a +b +c) = -4 ⇒ b +0 = -4 ⇒ b = -4
c +(a +b +c) = 4 ⇒ c +0 = 4 ⇒ c = 4

slope-intercept form, write the equation of the line
that passes through the point (4, 2) with a slope of 5.
Answer:
[tex]y=5x-18[/tex]
Step-by-step explanation:
Given the following question:
Point A = (4, 2) = (x, y)
Slope = 5
To find the answer we are going to have to use the formula for slope intercept, substitute the values, then solve for the variable b to have our answer.
[tex]y=mx+b[/tex]
[tex]y=2[/tex]
[tex]m=5[/tex]
[tex]x=4[/tex]
[tex]2=5(4)+b[/tex]
[tex]5\times4=20[/tex]
[tex]2=20+b[/tex]
[tex]20-20=0[/tex]
[tex]2-20=-18[/tex]
[tex]-18=b[/tex]
[tex]b=-18[/tex]
[tex]y=5x-18[/tex]
Your answer is "y = 5x - 18."
