Answer:
f(3) =16
Step-by-step explanation:
f(x) = 3x + 7
Let x= 3
f(3) = 3*3 +7
= 9+7
= 16
Answer: 16
Step-by-step explanation: f(x) = 3x + 7 means that if we put an x into our function, a 3x + 7 comes out.
So if we want to find f(3), we're putting a 3 into our function which means that a 3(3) + 7 comes out which simplifies to 9 + 7 or 16.
So f(3) = 16 or the value of the function at 3 equals 16.
13. In a week the prices of a bag of rice were 350,280,340,290,320, 310,300. The range is
A. 60
B. 70
C. 80
D. 100
so the right answer is 70.
Look at the attached picture ⤴
Hope it will help u
Answer:
B
Step-by-step explanation:
The range can be found by subtracting the lowest number from the highest number
First, arrange the numbers in order from least to greatest
350,280,340,290,320, 310,300
280, 290, 300, 310, 320, 340, 350
So, our lowest number is 280, and our highest is 350.
highest number - lowest number
Subtract 280 from 350
350-280
70
So, our range is 70, making B the correct answer

What is Metric System?Everything around us has a measurement value, from the amount of sugar you put in a cake to the size of a football field. Each thing is measured differently based on its length, weight, volume, or duration. With these measurements, the idea of "Metric System" is introduced.
Given that, 1 gallon is 4 quarts, and 1 quart is 2 pints.
Metric Conversion refers to the conversion of the given units to desired units for any quantity to be measured.
Here, 1 gallon = 4 quarts
1 quarts = 2 pints
1 gallon = 4×2
= 8 pints

Metric countries rate the fuel efficiency of a car by the number of liters of gasoline required to drive 100 kilometers. If a car takes 9 liters per 100 kilometers, what is its efficiency in miles per gallon? Use the conversions 1 gal= 3.7854 L and 1 mile = 1.6 km.
WILL MARK BRAINLIEST
The efficiency of the car in unit miles per gallon will be 26.28.
What is unit conversion?To convert any unit into another is called a unit conversion.
In order to convert units, we need to care about their dimensions their dimension should not be changed.
Given that,
The car takes 9 liters per 100 kilometers
9 liters ⇒ 100 km
Since 1 gal= 3.7854 L → 1 L = (1/3.7854) gal
9 L = (9/3.7854) gal
1 mile = 1.6 km → 1 km = (1/1.6) miles
100 km = (100/1.6) miles
So, (9/3.7854) gal ⇒ (100/1.6) miles
Efficiency = (100/1.6) ÷ (9/3.7854)
Efficiency = 26.28 miles/gal
Hence "The efficiency of the car in unit miles per gallon will be 26.28".

Express 8^1/2 in simplest radical form.
Final answer:
To express [tex]8^{1/2[/tex]in simplest radical form, recognize that it's equivalent to the square root of 8, then simplify to 2√2 by breaking down 8 into prime factors and finding pairs of factors.
Explanation:
To express [tex]8^{1/2[/tex] in simplest radical form, we follow these steps:
Recognize that an exponent of 1/2 is equivalent to the square root.
Find the square root of 8, which can also be written as √8.
Since 8 is not a perfect square, we can simplify it by breaking it down into its prime factors: 8 = 2 x 2 x 2.
Group the factors into pairs to determine the square root: 8 has one pair of 2s.
This pair comes out of the radical as a single 2, leaving one 2 inside the radical: 2√2.
Therefore, 8^1/2 simplifies to 2√2, which is the simplest radical form.

1/3 of the difference of 20 and 2
Answer:
the correct answer is 6
Step-by-step explanation:
hope it helps !
To find 1/3 of the difference of 20 and 2, subtract 2 from 20 to get the difference, then divide the difference by 3.
Explanation:To determine one-third of the difference between 20 and 2, we first find the difference itself, which is 20 - 2 = 18. Then, recognizing that one-third represents dividing by 3, we divide the difference, 18, by 3, resulting in 18 ÷ 3 = 6. This mathematical process illustrates the sequential steps taken to solve the problem. The method involves subtraction to identify the difference and subsequent division by 3 to find the desired fraction. This systematic approach ensures clarity in understanding the solution. Hence, one-third of the difference between 20 and 2 equals 6, demonstrating the application of basic arithmetic concepts in solving real-world problems and enhancing mathematical reasoning skills.

[tex] \sqrt{ - 6} \times \sqrt{ - 10} [/tex]
[tex] = \sqrt{ - 6 \times - 10} [/tex]
[tex] = \sqrt{60} [/tex]
Next, you have to find the common factors of 60 :
60 = 1×60
60 = 2×30
60 = 3×20
60 = 4×15
60 = 5×12
60 = 6×10
In order to simplify, we have to choose a perfect square from the factors above. In the factors above, 4 is a perfect square so that we can square root it :

Joseph is ordering a taxi from an online taxi service. The taxi charges $4 just for the
pickup and then an additional $1 per mile driven. How much would a taxi ride code if
Joseph is riding for 9 miles? How much would a taxi ride cost that is m miles long?
Answer: $13 for the 9 mile ride.
The taxi ride that is m miles long would cost as follows: 4 + m
Step-by-step explanation:
The cost of Joseph's taxi ride is calculated by adding a flat fee of $4 to $1 for each mile driven. Thus, a 9-mile ride would cost $13. For a ride of m miles, the cost would be $4 plus $1 per mile.
Explanation:The cost of a taxi ride can be determined using a function that considers two components: a flat fee, and a rate per mile. In Joseph's case, the online tax service charges a $4 flat fee for pickup, and $1 per each mile driven. Hence, the equation for the cost of a taxi ride (C) for Joseph is as follows: C= 4+1*m.
For a ride of 9 miles, we would substitute m with 9: C = 4+ 1*9, which simplifies to C = $13. Therefore, a 9-mile ride would cost $13.
For a taxi ride that is m miles long, the cost would be C = 4 + 1*m. The 4 represents the flat fee, and the 1*m represents the cost per mile that is driven multiplied by the number of miles in the ride. Therefore, a taxi ride that is m miles long would cost $4 plus $1 per mile.

What is an inverse function?A function is defined as the expression that set up the relationship between the dependent variable and the independent variable. In an inverse function, the value of two variables x and y are interchanged, and then the value of y is given an inverse function.
Given function is f(x) = ( 10/9x) + 11. the inverse function will be calculated as below:-
y = 10/9x+11
x = ( 10 / 9y ) + 11
x - 11 = ( 10 / 9y )
9y / 10 = ( 1 / ( x - 11 )
9y = 10 / ( x - 11 )
y = ( 10 ) / ( 9x - 99 )
Therefore, the inverse function of the given function will be f(x)⁻¹ = ( 10 ) / ( 9x - 99).

X. X
Final answer:
To find the probability of spinning a 3 and then a 4, we calculate the individual probabilities of each event (1/6 each) and multiply them, resulting in a combined probability of 1/36.
Explanation:
The question asks about the probability of spinning a 3 followed by a 4 on a spinner. Assuming the spinner has equal sections numbered from 1 to 6, similar to a six-sided die, we can calculate the probability of each individual spin and then combine them to find the overall probability of the sequence happening.
The probability of spinning a 3 on the first spin is 1/6, and similarly, the probability of spinning a 4 on the subsequent spin is also 1/6. Since these two events are independent, we multiply these probabilities to find the combined probability of both events happening in sequence:
Probability of spinning a 3 then a 4 = Probability of 3 on first spin × Probability of 4 on second spin
= (1/6) × (1/6)
= 1/36
Therefore, the probability of spinning a 3 and then a 4 in two spins is 1/36.
