Correct question:
Adrian needs to be at school at 7:45 am. It takes him 15 minutes to walk to school, 5/12 hour to eat breakfast, 0.7 hour to get dressed, and 0.15 hour to shower. What time should he wake up.
Answer:
Adrian should wake up by 6.14 am
Step-by-step explanation:
Given;
time to walk to school, = 15 mins
time to eat breakfast = 5/12 hour = 25 mins
time to get dressed = 0.7hour = 42 mins
time to shower = 0.15 hour = 9 mins
time Adrian needs to be in school = 7.45 am
Count from this time he needs to be at school backwards by subtracting the time he will spend before reaching school;
7.45 am - 15 mins = 7.30 am
7.30 am - 25 mins = 7.05 am
7.05 am - 42 mins = 6.23 am
6.23 am - 9 mins = 6.14 am
Therefore, Adrian should wake up by 6.14 am
John is 4 years younger than twice Michael's age. Michael is John's younger brother. John is 18 years old. How old is Michael? Choose the equation that represents the situation.
Answer:
18=2m-4
Step-by-step explanation:
18 is the age of John. M represents the age of Michael. John is older than Michael so instead of 18=4-2m it is 18=2m-4. If you do 8=4-2m it will be inccorect because it will give you a negative. Michael is 11 years old.
Rewrite equation in slope intercept form, if necessary. Then determine whether the lines are parallel. Explain. 23. Y = -x + 6 24. Y - 7x = 6 25. 3x + 4y = 12 26. 2x + 5y = -1 x + y = 20 y + 7x = 8 6x + 2 = 6 10y = -4x - 20
Answer:
Step-by-step explanation:
Slope intercept form
[tex]y= mx + c[/tex]
m=slope
c= intercept
1) y= -x + 6
2) y=7x + 6
3) y= -3/4x + + 3
4) y= -2/5x - 1/5
5) y= -x + 20
6) y= -7x + 8
7) y= -3x + 3
8) y= -2/5x -2
Line 1 and 5 are parallel because both have the same slope of -1
line 4 and 8 are also parallel as the their slopes are -2/5

Maddie, Jaeahna, Chelsea and Onella swam in the relay for Colyton at district . If the complete lap times added to 137.009 seconds. What was the average lap time for each swimmer?
Answer:
34.25 seconds
Step-by-step explanation:
Given that :
Summation of the complete lap time of each of the four swimmers = 137.009 seconds
The average lap time for each of the four swimmers will be :
The average of the total lap time ;
Total lap time / number of swimmers
= 137.009 / 4
= 34.25225 seconds
Hence, each swimmer has an average lap time of 34.25 seconds

The cost of 24 caps is $150. Find the cost of each cap.
Answer:
6.25
Step-by-step explanation:
Divide 150 $ to 24 caps on your calculator
If the cost of 24 caps is $150, then the cost of each cap is $6.25.
What is unitary method?We know that a single unit's value can be determined from the values of multiple units, and multiple units' values can be determined from the values of single units using the unitary method. We typically use this technique for math calculations. We are able to locate the missing value using the unitary method.
How to solve it?Given that the cost of 24 caps is $150.
Then the cost of 1 cap is 150/24 = $6.25
Therefore we can conclude that If the cost of 24 caps is $150, then the cost of each cap is $6.25.

5x^2-22x+8=0
can you find the roots?
Step-by-step explanation:
Answer:
x = [tex]\frac{2}{5}[/tex], x = 4
Step-by-step explanation:
Given
5x² - 22x + 8 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 5 × 8 = + 40 and sum = - 22
The factors are - 20 and - 2
Use these factors to split the x- term
5x² - 20x - 2x + 8 = 0 ( factor the first/second and third/fourth terms )
5x(x - 4) - 2(x - 4) = 0 ← factor out (x - 4) from each term
(x - 4)(5x - 2) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4
5x - 2 = 0 ⇒ 5x = 2 ⇒ x = [tex]\frac{2}{5}[/tex]
Two ice cream shops in the mall sell sundaes. Let x equal the number of scoops of ice cream. Larry's Ice Cream Shop's price is represented by the expression 1.2x + 1. Ice Cream World's price is represented by the expression 0.4(0.3x + 1) . Which statement is true?
Choose the correct answer below.
A.
The two shops charge the same price for a 3-scoop sundae.
B.
The two shops charge the same price for a 2-scoop sundae.
C.
The two shops never charge the same price for sundaes with the same number of scoops.
D.
The two shops always charge the same price for sundaes with the same number of scoops.
Answer:
the answer is D.
Step-by-step explanation:
this is because if you distribute 0.4 times 0.3 you get 0.12.
then you are left with 0.12+1 which means both shops charge the same price.

In March, Terell weighed 104 1/3 pounds.
In June, he weighed 109 1/2 pounds.
How much weight did Terell gain
between March and June?
Answer:
Terell gained 5 and 1/6 pounds between March and June
Step-by-step explanation:
1. 109 - 104 = 5
2. Convert 1/3
1/3 = 2/6
3. Convert 1/2
1/2 = 3/6
4. Subtract them
3/6 - 2/6 = 1/6
(Full equation: 109 and 1/2 - 104 and 1/3 = 5 and 1/6 pounds)

PLEASE HELP Rob wants to buy a new canoe that will cost $720. How many months will it take him to save enough money to buy it if his cash inflows average about $420 a month and his current cash outflows are $360 a month?
Answer:
12 months
Step-by-step explanation:
if the amount of money rob makes a month is $420 and the amount he spends a month is $360 then subtract the two. if you do this you should get 60 and the you find 60 times what = $720
A car salesman gets paid $3,750 each month plus 8.5% commission on his total sales. This month he sold 5 cars for a total of $138,000. What are his monthly total earnings?
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let y represent the total money the salesman earns for selling a total of $x sales. Hence:
y = 0.085x + 3750
If the salesman makes a total of $138000, hence:
y = 0.085(138000) + 3750
y = 15480
The car salesman total earnings if he sold 5 cars for a total of $138,000 is $15480.
