Can ratios have decimals in them or do all the numbers have to be integers? E.g. is 7.8:1.3:6.5 a valid ratio?
Answers
78:13:65
It also depends on what your teacher is asking of you.
Final answer:
Yes, ratios can include decimals. They can represent quantities in numerous contexts such as scale distances, dimensions, and proportions. The ratio 7.8:1.3:6.5 is, therefore, a valid expression.
Explanation:
Ratios can indeed include decimals in them; they do not need to be limited to integers. Ratios are a way to compare two or more quantities, which can be whole numbers, fractions, or decimals. Just as fractions, ratios express the relationship between parts of a whole or between two quantities in a specific order. For example, the ratio 7.8:1.3:6.5 is valid and represents the relative quantities of three different entities. In many contexts, such as in scale distances or dimensions, the use of decimal ratios is quite common. When dealing with scale factor to find actual dimensions, the ratio could also include decimals, as it compares the scale dimensions to actual dimensions of an object or distance. For example, on a map with a unit scale of 1 inch equals 100 feet, the ratio would be written as 1/100 or in decimal form, 0.01/1.
4a - 4( 15a - 2) - 8
Answers
The problem to solve: 4a - 4(15a - 2) - 8
The first thing to do is to apply the Distributive Property, which is: a(b + c) = ab + ac.
Here we have: -4(15a - 2). We must multiply -4 by 15a and -2. Let's do it.
4a - 4(15a - 2) - 8
4a - 60a + 8 - 8
Now we can go ahead and combine like terms; add the constants and add the a-terms. 4a minus 60a is equal to negative 56a. 8 minus 8 is zero, so the 8's cancel out, and we're left with:
-56a
That's your answer! I hope this helps you. (:
In order to simplify this expression (notice how it's an expression and not an equation because it's not set equal to something) we can use addition and subtraction, and the distributive property which is defined as:
a(b+c) = ab + ac
Using this property, we can simplify this expression to:
4a - 60a + 8 - 8
Notice how -4(-2) was positive 8.
Simplify "a" terms:
-56a + 8 - 8
Since it's +8 - 8, the 8's cancel out.
Therefore, we just have -56a.
Hope this helps!
When Mr. Krumm purchased a tie he paid $9.27, which included the 3% sales tax. How many dollars did the tie cost before the tax was included?
Answers
103% = 9.27
To find the price before tax, we need to find 100% of the price.
103% = 9.27
1% = 0.09
100% = 0.09 x 100 = $9

What is the distance between the points (3, 12) and (14, 2)?
Answers
Answer:
√221 or 14.866
Step-by-step explanation:
The distance formula is
[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}[/tex]
Using our coordinates, we have
[tex]d=\sqrt{(12-2)^2+(3-14)^2}\\\\=\sqrt{10^2+(-11)^2}\\\\=\sqrt{100+121}\\\\=\sqrt{221}\approx 14.866[/tex]
The distance between the points (3, 12) and (14, 2) is 14.86 units.
What is the distance between two points?The distance between two points [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
For given example,
We need to find the distance between points (3, 12) and (14, 2)
Consider given points as,
[tex](x_1,y_1)=(3,12)\\\\(x_2,y_2)=(14,2)[/tex]
Using the distance formula, the distance between two points would be,
[tex]\Rightarrow d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\\\\Rightarrow d=\sqrt{(14-3)^2+(2-12)^2}\\\\\Rightarrow d=\sqrt{(11)^2+(-10)^2}\\\\\Rightarrow d=\sqrt{121+100}\\\\\Rightarrow d=\sqrt{221}\\\\\Rightarrow d=14.86~units[/tex]
Therefore, the distance between the points (3, 12) and (14, 2) is 14.86 units.

Serena is making a model of one of the Egyptian pyramids. The square base has sides that are all 4.4 in. Each of the triangular faces has a base of 4.4 in and a height of 3.8 in. How much paper would it take to cover the entire pyramid?
A.
73.57 sq in
B.
82.78 sq in
C.
52.8 sq in
D.
12.6 sq in
Answers
Area of a Square: Length x Width
A = 4.4 x 4.4
A = 19.36
Area of a Triangle: [tex] \frac{Base x Height}{2} [/tex]
A = 4.4 x 3.8 ÷ 2
A = 8.36
** We have 4 triangles, and 8.36 is the area for ONE triangle. We can multiply this by 4 to determine the area of all of the triangles together.
8.36 x 4 = 33.44
Now that we have our area for the base of the pyramid and the walls of the pyramid, we can add them together to determine the total area, and how much paper Serena will need.
19.36 + 33.44 = 52.8
So, Serena will need 52.8 [tex] in^{2} [/tex] of paper to cover the entire pyramid.

Answers
A = 1/2 bh
198 = 1/2 x b x 12
198 = 6b
b = 33 cm
We know the total area and we know the slant height is 12 cm so we substitute these in and solve for h.
The length of the base edge is 33 cm. You should substitute this back in to check.
1/2 x 33 x 12 = 198 square cm.

The length of the minute hand is 200% of the length of the hour hand.
In 1 hour, how much farther does the tip of the minute hand move than the tip of the hour hand? Round your answer to the nearest hundredth.
(The length of the hour hand is 20mm)
Answers
This is because each circumference is equal to 2[tex] \pi [/tex]r. So the distance the minute hand would travel would be 40[tex] \pi [/tex]. Then the minute hand would have a circumference of 20[tex] \pi [/tex]. However, you would have to divide that by 12 since it only traveled 1/12th of the distance around.
When you subtract the hour hand's distance from minute hand's distance, you get the answer above.

Explain how you can compare the size of a product to the size of a factor when multiplying fractions without actually doing multiplication including model
Answers
Imagine, if you had half a pizza and you ate one-half of that. You would multiply 1/2 by 1/2 and get an even smaller number. The result would be 1/4.
On the other hand, if you multiply a number by a mixed number that is larger than one, the result would be larger than when you started.
The Comparison size of product and factors is shown below.
What are factors?A factor is a number that completely divides another number. To put it another way, if adding two whole numbers results in a product, then the numbers we are adding are factors of the product because the product is divisible by them.
For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly.
A fraction less than one will result in a smaller product than the initial fraction when multiplied by a number.
Imagine that you only ate half of the pizza you ordered.
You would get a smaller value if you multiplied 1/2 by 1/2. It would come out to 1/4.
On the other hand, the outcome would be more than the starting value if you multiplied a number by a mixed number that is greater than one.

A bicyclist heads east at 10km/h. After she has traveled 24.2 kilometers, another cyclist sets out in the same direction going 30km/h. About how long will it take the second cyclist to catch up to the first cyclist?
Answers
[tex]t= \frac{24.2}{10} [/tex]
[tex]t=2.42[/tex]
So, we know that she has traveled for 2.42 hours.
We also know that after she has traveled for 2.42 hours another cyclist sets out in the same direction, so if [tex]t[/tex] represents the time of our first cyclist, the time of our second cyclist will be [tex]t-2.42[/tex].
Now we are going to use the equation [tex]distance=(speed)(time)[/tex] to relate the speeds and times of the two cyclist:
For the first one:
[tex]distance=10t[/tex] equation (1)
For the second one:
[tex]distance=30(t-2.42)[/tex] equation (2)
Replace (1) in (2)
[tex]10t=30(t-2.42)[/tex]
The only thing left now is solve for [tex]t[/tex]:
[tex]10t=30t-72.6[/tex]
[tex]-20t=-72.6[/tex]
[tex]t= \frac{-72.6}{-20} [/tex]
[tex]t=3.63[/tex]
We can conclude that the second cyclist will catch up the first cyclist after 3.63 hours.
