Explain how rates and ratios are related. Be sure to include examples to support you response.
Answer:
Both rates and ratios are a comparison of two numbers. A rate is simply a specific type of ratio. The difference is that a rate is a comparison of two numbers with different units, whereas a ratio compares two numbers with the same unit. For example, in a room full of students, there are 10 boys and 5 girls. This means the ratio of boys to girls is 10:5.
Identify the slope and intercept of the following linear equation.
y=3/7x-5
A. Slope: 3/7; intercept: 5
B. Slope: 3/7; intercept: -5
C. Slope: 5; intercept: 3/7
D. Slope: -5; intercept: 3/7
Answer:
3/7 is the slope and -5 is the y intercept
Step-by-step explanation:
y=3/7x-5
The equation is written in slope intercept form
y = mx+b where m is the slope and b is the y intercept
3/7 is the slope and -5 is the y intercept
Answer:
B
Step-by-step explanation:
The slope is always the coefficient of the x value in the linear equation. And the y intercept is the constant in the equation.
Rewrite, using the distributive
property.
-3(5x – 10) = [?]x +[ ]
Answer:
-15x + 30
Step-by-step explanation:
Using the distributive property, distribute -3 to the parentheses:
-3(5x) = -15x
-3(-10) = 30
Add these terms together:
-15x + 30 is the rewritten expression
Answer:
-15x + 30
Step-by-step explanation:
-3*5 = -15 and -3 * -10 equals 30 also negative times a negative is always a positive number

100 random samples were taken from a large population. A particular numerical characteristic of sampled items was measured. The results of the measurements were as follows: 45 measurements were between 0.859 and 0.900 0.901 was observed once 0.902 was observed three times 0.903 was observed twice 0.904 was observed four times The smallest value was 0.859, and the largest value was 0.958. The sum of all 100 measurements was 91.170. Except those noted, no measurements occurred more than twice. What is the median of the measurements
Answer:
The median is [tex]Median = 0.903[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 100
The [tex]1^{st} \to 45^{th}[/tex] measurements is [tex]= 0.859 \to 0.900[/tex]
Generally since that after 0.900 we have 0.901 , then the
[tex]46^{th} \ measurement \ is \ 0.901[/tex]
in the same manner the [tex]47^{th} \ measurement \ is \ 0.902[/tex],
Given that 0.902 was observed three times it means that
[tex]47^{th},48^{th},49^{th} \ measurement \ is \ 0.902[/tex],
Given that 0.903 was observed two times it means that
[tex]50^{th},51^{th} \ measurement \ is \ 0.903[/tex],
Given that 0.903 was observed four times it means that
[tex]52^{nd},53^{rd},54^{th},55^{th} \ measurement \ is \ 0.904[/tex],
Given that the highest measurement is 0.958 then then the [tex]56^{th} \to 100^{th} \ measurement \ is \ between \ 0.905 \to 0.958[/tex]
Generally the median is is mathematically represented as
[tex]Median = \frac{ [\frac{n^{th}}{2}] + [(\frac{n}{2})^{th} + 1 ]}{2}[/tex]
=> [tex]Median = \frac{ [\frac{100^{th}}{2}] + [(\frac{100}{2})^{th} + 1 ]}{2}[/tex]
=> [tex]Median = \frac{ [50^{th}] + [51^{th} ]}{2}[/tex]
=> [tex]Median = \frac{ 0.903 + 0.903}{2}[/tex]
=> [tex]Median = 0.903[/tex]
how will you know that the equation is a quadratic
Answer:
A quadratic condition is a condition of the subsequent degree, which means it contains, in any event, one term that is squared. The standard structure is ax² + bx + c = 0 with a, b, and c being constants, or mathematical coefficients, and x is an obscure variable.

How is 41/1,000 written as a decimal? Enter your answer in the box.
Answer:
0.041
I know this because 1,000 has 3 zeros, so you would move 41 three places to the right.
The decimal equivalent of the fraction 41/1000 is 0.041.
What is a decimal?A decimal is represented by a dot that separates the whole part and the fractional part of a number. Decimals can also be converted into fractions and vice versa.
Given, a fraction 41/1000, here the numerator is less than the denominator so it is a proper fraction.
Now, As in the denominator we have three zeroes we'll put a decimal three places before the numerator value which is,
= 0.041/1.
= 0.041.
So, 41/1000 is equal to 0.041.

If the quotient of a number and 16 is added to 1/4 the result is 5/16
Answer:
if youre trying to find the number then the number is 1
Step-by-step explanation:
the equation would be x/16+1/4=5/16
well we want to make everything have the same denominator and 16 is the LCD ( least common denominator ) so you would multiply 1/4 by 4/4 to get 4/16.
this means x/16+4/16=5/16 and and 4+1=5 so 1 is the answer

[tex]\boxed{2^{\frac{802}{27}} \cdot 3^9}[/tex]
Step-by-step explanation:
I will try to give as many details as possible.
First of all, I just would like to say:
[tex]\text{Use } \LaTeX ![/tex]
Texting in Latex is much more clear and depending on the question, just writing down without it may be confusing or ambiguous. Be together with Latex! （＊＾Ｕ＾）人（≧Ｖ≦＊）/
[tex]$(3^{-2} \cdot 4^{-5} \cdot 5^0)^{-3} \cdot (4^{-\frac{4}{3^3} })\cdot 3^3$[/tex]
Note that
[tex]\boxed{a^{-b} = \dfrac{1}{a^b}, a\neq 0 }[/tex]
The denominator can't be 0 because it would be undefined.
So, we can solve the expression inside both parentheses.
[tex]\left(\dfrac{1}{3^2} \cdot \dfrac{1}{4^5} \cdot 5^0 \right)^{-3} \cdot \left(\dfrac{1}{4^{\frac{4}{3^3} } }\right)\cdot 3^3[/tex]
Also,
[tex]\boxed{a^{0} = 1, a\neq 0 }[/tex]
[tex]\left(\dfrac{1}{9} \cdot \dfrac{1}{1024} \cdot 1 \right)^{-3} \cdot \left(\dfrac{1}{4^{\frac{4}{27} } }\right)\cdot 27[/tex]
Note
[tex]\boxed{\dfrac{1}{a} \cdot \dfrac{1}{b}= \frac{1}{ab} , a, b \neq 0}[/tex]
[tex]\left(\dfrac{1}{9216} \right)^{-3} \cdot \left(\dfrac{1}{4^{\frac{4}{27} } }\right)\cdot 27[/tex]
[tex]\left(\dfrac{1}{9216} \right)^{-3} \cdot \left(\dfrac{27}{4^{\frac{4}{27} } }\right)[/tex]
[tex]\left( \dfrac{1}{\left(\dfrac{1}{9216}\right)^3} \right)\cdot \left(\dfrac{27}{4^{\frac{4}{9} } }\right)[/tex]
[tex]\left( \dfrac{1}{\left(\dfrac{1}{9216}\right)^3} \right)\cdot \left(\dfrac{27}{4^{\frac{4}{27} } }\right)[/tex]
Note
[tex]\boxed{\dfrac{1}{\dfrac{1}{a} } = a}[/tex]
[tex]9216^3\cdot \left(\dfrac{27}{4^{\frac{4}{9} } }\right)[/tex]
[tex]\left(\dfrac{ 9216^3\cdot 27}{4^{\frac{4}{27} } }\right)[/tex]
Once
[tex]9216=2^{10}\cdot 3^2 \implies 9216^3=2^{30}\cdot 3^6[/tex]
[tex]\boxed{(a \cdot b)^n=a^n \cdot b^n}[/tex]
And
[tex]$4^{\frac{4}{27}} = 2^{\frac{8}{27} $[/tex]
We have
[tex]\left(\dfrac{ 2^{30} \cdot 3^6\cdot 27}{2^{\frac{8}{27} } }\right)[/tex]
Also, once
[tex]\boxed{\dfrac{c^a}{c^b}=c^{a-b}}[/tex]
[tex]2^{30-\frac{8}{27}} \cdot 3^6\cdot 27[/tex]
As
[tex]30-\dfrac{8}{27} = \dfrac{30 \cdot 27}{27}-\dfrac{8}{27} =\dfrac{802}{27}[/tex]
[tex]2^{30-\frac{8}{27}} \cdot 3^6\cdot 27 = 2^{\frac{802}{27}} \cdot 3^6 \cdot 3^3[/tex]

Answer:
if x = 12; y = 40
if x = 3; y= 13
Step-by-step explanation:
if x = 12 then,
y = 3(12) + 4

y = 40
if x = 3 then,
y = 3(3) + 4
y = 9 + 4
y = 13

Answer:
B. x +6y = 4.45; x +12y = 5.65
Step-by-step explanation:
The problem statement defines the variables for you. Using x and y for the cost of a loaf and the cost of an egg, respectively, each purchase can be represented by an equation of the form ...
(number of loaves)x + (number of eggs)y = (amount spent)
The first purchase is described as
number of loaves = 1number of eggs = 6amount spent = 4.45equation: x +6y = 4.45The second purchase is of a dozen eggs, which is 12 eggs. The description of this purchase can be ...
number of loaves = 1number of eggs = 12amount spent = 5.65equation: x +12y = 5.65The situation can be represented by the equations shown in the attachment.
What's the Constant of Proportianlity/Unit Rate?
Answer:
1/3 cup of juice per cup of berries
Step-by-step explanation:
The table shows that if we go from 0 to 4 cups (a "run" of 4 cups), the juice output is 1 1/3 (or 4/3) (a "rise" of 4/3 cups), and so the desired constant of proportionality is the unit rate
(4/3) cups
------------------------ = 1/3 cup of juice per cup of berries
