#CMIIWwhat operation do you use to convert from a larger measurement unit to a smaller measurement unit? Explain why
Answer:
Use multiplication and dividing.
Step-by-step explanation:
If you want to convert to a smaller unit, you must multiply.
For example...
4 Feet to Inches:
[tex]4 * 12 =48[/tex] inches
2 Yards to Inches:
[tex]2 * 3 = 6[/tex] feet
[tex]6 * 12 = 72[/tex] inches
If you want to convert to a larger unit, you must divide.
336 Inches to Feet:
[tex]336/12=28[/tex] feet
756 Inches to Yards:
[tex]756/12=63[/tex] feet
[tex]63/3=21[/tex] yards

Solve it and show the work because i need to show the work
Answer:
x = -22
Step-by-step explanation:
Subtract 5 from both sides
3x + 5 (-5) = 2x - 17 (-5)
3x = 2x - 17
Subtract 2x from both sides
3x (-2x) = 2x (-2) -22

The price of 2 ratios are in x:y when the prices both increase by £20, the ratio becomes 5:2 when the prices both reduce by £5 the ratio becomes 5:1 express the x:y ratio in the lowest form
Answer:
x:y = 4:1
Step-by-step explanation:
Since their ratios are x:y, when they both increase by £20, their ratio is 5:2.
So, x + 20/(y + 20) = 5/2 (1)
When they both decrease by £5, their ratio is 5:1.
So, x - 5/(y - 5) = 5/1 (2)
Simplifying (1) and (2), we have
x + 20/(y + 20) = 5/2 (1)
cross-multiplying, we have
2(x + 20) = 5(y + 20)
expanding the brackets, we have
2x + 40 = 5y + 100
2x - 5y = 100 - 40
2x - 5y = 60 (3)
So,
x -5/(y - 5) = 5/1 (2)
cross-multiplying, we have
(x - 5) = 5(y - 5)
expanding the brackets, we have
x - 5 = 5y - 25
x = 5y - 25 + 5
x = 5y - 20 (4)
Substituting (4 into (3), we have
2x - 5y = 60 (3)
2(5y - 20) - 5y = 60
10y - 40 - 5y = 60
10y - 5y = 60 + 40
5y = 100
y = 100/5 = 20
substituting y = 20 into (4), we have
x = 5y - 20 (4)
x = 5(20) - 20
x = 100 - 20
x = 80
So, x/y = 80/20 = 4
x/y = 4/1
x:y = 4:1

A certain television is advertised as a 54-inch TV (the diagonal length). If the width of the TV is 40 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
36.3
Step-by-step explanation:
I tried using the Pythagorean Theorem to measure the length (tallness) of the TV.
[tex]a^2 + b^2 = c^2[/tex]
[tex]a^2 + (40)^2 = (54)^2[/tex]
[tex]a^2 + 1600 = 2916[/tex]
[tex]a^2 = 2916-1600 = 1316[/tex]
[tex]a = \sqrt{1316}[/tex]
[tex]a = 36.27671429[/tex]
When this is rounded up to the nearest tenth, it would go up to 36.3.
So, the length (tallness) of the TV would be 36.3 inches.
If two numbers HCF is 5 and LCM is 60. One number is 15 then what is the second number
Answer:
LCM x HCF = Product of the two numbers.
Step-by-step explanation:
HCF = 5
LCM = 60
Therefore, 5 x 60 = 15x the other number.
300 = 15x the other number
the other number = 300/15
The other number = 20

Volume=125 cu ft
Length=5 ft
Width=?___
Height=5 ft
Answer:
5 ft.
Step-by-step explanation:
First, start with a formula. To find the volume, you have to multiply the length, width, and height.
V = lwh
Plug in the variables that you already know.
125 = 5 ⋅ w ⋅ 5
Simplify.
125 = 25w
Divide both sides by 25 to isolate w.
5 = w
There are 16 rats in a cage. The ratio of white rats to all rats is 3:4. How many white rats are in the cage?
Answer:
There are 12 white rats in the cage.
Step-by-step explanation:
3 : 4 The question says there are 16 rats in the cage. Meaning that 16 is the
x4 x4 total. Since 4(from the ratio)x4 is 16. You would multiply 4 on both sides.
12 : 16
Meaning there are 12 white rats to 16 total rats.

What is the summation notation for the geometric series 1/2+2 + 8 +32+128
Answer:
D
Step-by-step explanation:
Edge
The summation of the given geometric series is 70.5.
What is geometric series ?
Geometric series is the sum of an infinite number of terms that have a constant ratio between the successive terms.
Formula for the sum of the nth term of a geometric series[tex]s_{n}= a\frac{(r^{n} -1)}{(r-1)}[/tex] (when r>1)
or
[tex]S_{n} =\frac{a(r^{n}-1) }{1-r}[/tex] (when r<1)
where,
r is the common ratio
a is the first term of first term of the series.
n is the total number of terms.
According to the given question
we have
geometric series [tex]\frac{1}{2} +2+8+32+128[/tex]
total number of terms, n=5
first term a =[tex]\frac{1}{2}[/tex]
[tex]r=\frac{2}{\frac{1}{2} }=4[/tex]
therefore,
summation of the given geometric series calculated as
[tex]s_{n} =\frac{1}{2} \frac{4^{5}-1 }{4-1}[/tex]
[tex]s_{n} =\frac{1023}{6}[/tex]
[tex]s_{n} = 170.5[/tex]
Hence, the summation of the geometric series is 170.5.

You observe the heights of two plants for an experiment. Plant A has a height of 8 centimeters and grows 1 centimeter each week. Plant B has
a height of 4 centimeters and grows 2 centimeters each week. Let x represent the number of weeks and let y represent the height of the
plant
a. Write a system of linear equations that represents this situation
System of equations:
b. Will the plants ever have the same height?
Using linear functions, it is found that:
a)
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
b) They will have the same height after 4 weeks.
A linear function has the following format:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change.b is the y-intercept, which is the value of y when x = 0.Item a:
Plant A has a height of 8 centimeters and grows 1 centimeter each week, hence:
[tex]y_A(x) = 8 + x[/tex]
Plant B has a height of 4 centimeters and grows 2 centimeters each week, hence:
[tex]y_B(x) = 4 + 2x[/tex]
The system is:
[tex]y_A(x) = 8 + x[/tex]
[tex]y_B(x) = 4 + 2x[/tex]
Item b:
Equaling the equations:
[tex]y_A(x) = y_B(x)[/tex]
[tex]8 + x = 4 + 2x[/tex]
[tex]x = 4[/tex]
They will have the same height after 4 weeks.

A rope is stretched from the top of a
7-foot tent pole to a point on the ground
12 ft from the base of the pole. How long
is the rope ?
Answer:
Step-by-step explanation:
we know two sides of a triangle, one side is 7 feet, the other is 12 feet , so use Pythagoras theorem
[tex]C^{2}[/tex] = [tex]A^{2}[/tex] + [tex]B^{2}[/tex]
[tex]C^{2}[/tex] = [tex]7^{2}[/tex] + [tex]12^{2}[/tex]
[tex]C^{2}[/tex] = 49 + 144
[tex]C^{2}[/tex] = 193
C = [tex]\sqrt{193}[/tex]
C = 13.89 feet
Answer:
The square of the hypotenuse equals the square of the sum of the other two sides.
13.89ft
Step-by-step explanation:
Definition Of Pythagoras Theorem :The Pythagorean theorem states that the total of the squares on a right triangle's legs equals the square on the hypotenuse (the side opposite the right angle)—or, in popular algebraic form, a2 + b2 = c2.
Given:Height of the Tent Pole = 7ft.
Base of the Pole of the Tent = 12ft.
Now we will use Pythagoras theorem to find how long the rope is.
Use of Pythagoras theorem
[tex]\begin{aligned}&C^{2}=A^{2}+B^{2} \\&C^{2}=7^{2}+12^{2} \\&C^{2}=49+144 \\&C^{2}=193 \\&C=\sqrt{193} \\&C=13.89 \text { feet }\end{aligned}[/tex]Hence, the length of the rope is 13.89ft.
