54(x+42)
what is the total distance travelled?
plzzzz helpppppppp
Answer:
Step-by-step explanation:
the corner points are O(0,0),A(45,10),D((100,10),E(120,0),G(160,0),H(200,5),F(240,5)
OA=√[(45-0)²+(10-0)²]=5√(9²+2²)=5√85≈46.1
DE=√[(120-100)²+(0-10)²]=√(400+100)=√500=10√5≈22.36
GH=√[(200-160)²+(5-0)²]=√1625≈40.31
Total distance travelled=46.1+22.36+40.31=108.77 km

The answer to the function is 102
First you must set up the equation
[tex]f(10)=3(10)(2)+6(10)-18[/tex]
Then you must multiply
[tex]f(10)=60 +60-18[/tex]
Finally, you must simplify like terms
[tex]f(10)=102[/tex]

Answer:
Area = 90 units^2
Step-by-step explanation:
For the area of a triangle, we can simply use the following equation:
Area = ( 1 / 2 ) * Base * Height
We are given a base of 12 and a height of 15, so we can simply plug those values into the formula to find the area.
Area = ( 1 / 2 ) * Base * Height
Area = ( 1 / 2 ) * 12 * 15
Area = 6 * 15
Area = 90
Hence, the area of our triangle is 90 units^2.
Cheers.

(a^(?))/(a^(10))= a^(4) help me
Answer:
a^? = 14
Step-by-step explanation:
a^? / a^10 = a^4
is also the same as
a^? - a^10 = a^4 ( due to laws of indices)
a^? = a^4 + a^10
a^? = a^14
the a's striking each other resulting in
? = 14

caitlyn has $210 in her savings account and she has to pay her parents $5 each month.Santos has $90 dollars and he saves $5 dollars each month. At this rate, when will Caitlyn and Santos have the same amount of money ? How much will they each have?
Answer:
After about 12 months both Caitlyn and Santos will have the same balance of 150 dollars in their bank account.
Step-by-step explanation:
Caitlyn's saving: -5x+210
Santos' saving: 5x+90
To know when the total amount in their bank account is the same you would need to make these linear equations equal to one another.
-5x+210 = 5x+90
(Add 5x on both sides)
210=10x+90
(Subtract 90 from both sides)
120=10x
(Simplify)
x=12
After about 12 months their total savings should be the same. To check what their balance will be plug the x value of 12 into both of these equations. This should give 150 as your answer for both equations.

Interested in learning more about its fans, the marketing office of the Arena Football League (AFL) conducted a survey at one of its games. The survey has 937 respondents, 694 males and 243 females. Out of the 937 total respondent's, 194 stated that they had attended multiple AFL games. Of these 194 fans that had attended multiple games, 169 were male. Using this survey information, answer the following questions.
1- What is the probability that a randomly selected fan has attended multiple games?2- Given that a randomly selected fan has attended multiple games, what is the probability of this person being male?3- What is the probability of a randomly selected fan being male and having attended multiple games?4- Given that a randomly selected fan is male, what is the probability that this person has attended multiple games?5- What is the probability that a randomly selected fan is male or has attended multiple games?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data:
Total respondent : n(T) = 937
n(male) = 694
n(Female) = 243
n(multiple AFL) = 194
_______________AFL
Male ____694___169
Female __243___ 25
Total____ 937___194
1.) What is the probability that a randomly selected fan has attended multiple games?
n(Multiple AFL) / n(Total)
= 194 / 937
= 0.207
2.) Given that a randomly selected fan has attended multiple games, what is the probability of this person being male?
Male who attended multiple AFL / n(multiple AFL)
= 169 / 194
= 0.871
3- What is the probability of a randomly selected fan being male and having attended multiple games?
Number of males who have attended multiple games / n(Total)
= 169 / 937
= 0.180
4- Given that a randomly selected fan is male, what is the probability that this person has attended multiple games?
Number of males who have attended multiple AFL / n(male)
169 / 694
= 0.2435
5- What is the probability that a randomly selected fan is male or has attended multiple games?
[n(male) + n(multiple AFL)] / n(Total)
(694 + 194) / 937
= 888 / 937
= 0.9477

tank after driving for 4 hours? How much gas would be left after t hours?
Answer:
5 gallons would be left
Step-by-step explanation:
Answer:
There would be 5 gallons of gas after 4 hours.
There would be 12 - 1.75t after t hours.
Step-by-step explanation:

Which operation should be used to solve x + 7 = 19?
÷ 7
– 7
x 7
+ 7
Which operation should be used to solve x + 7 = 19?
÷ 7
– 7
x 7
+ 7
Answer:-7 is the correct answer.
Solution:Because when we'll use -7 then the 7 in the LHS will get cancelled.
x + 7 = 19
or, x + 7 - 7 = 19 - 7
or, x = 12

What is the probability that a randomly chosen applicant has over 5 years of experience, given that the applicant has a graduate degree? Enter a fraction or round your answer to 4 decimal places, if necessary.
Answer:
0.2390Step-by-step explanation:
Given
Total applicants = 431Applicants with graduate degree and over 5 years of experience = 103Probability = favorable outcomes/total outcomes

103/431 = 0.2390 rounded to 4 decimal placesWhat is 8.865 rounded to the nearest whole number?
Answer:
9
Step-by-step explanation:
8.865 to the nearest whole number is 9, nine is a whole number because there are no decimals following, and since the number "8" is greater than 5, we round up, which would cause it to be 8.900, so to the nearest whole number, it would be 9.
