Answer:
2 11/12
Step-by-step explanation:
total amount fred used = 1/3 x 7 = 7/3
total amount Janice used = 1/4 x 7 = 7/4
total amount used =
7/3 + 7/4
(28 + 21) / 12 = 49 / 12 = 4 1/12
Amount left = 7 - 4 1/12 = 2 11/12

Laurie is painting the walls of her kitchen. It took Laurie 3 hours to paint 20% of the walls in her kitchen. How many total hours did Laurie take to paint the walls of her kitchen?
Answer:
Total time taken by Laurie to cover all kitchen walls = 15 hours
Step-by-step explanation:
Given:
Time taken by Laurie to cover 20% of kitchen walls = 3 hours
Find:
Total time taken by Laurie to cover all kitchen walls
Computation:
Total time taken by Laurie to cover all kitchen walls = Time taken for 20%[100%/20%]
Total time taken by Laurie to cover all kitchen walls = 3[10/2]
Total time taken by Laurie to cover all kitchen walls = 3[5]
Total time taken by Laurie to cover all kitchen walls = 15 hours

Diego’s family car holds 18 gallons of fuel. Each day the car uses 0.6 gallons of fuel. A warning light comes on when the remaining fuel is 1.5 gallons or less. Starting from a full tank, can Diego's family drive the car for 28 days without the warning light turning on? Explain your answer.
please help!!
Answer:
Diego's family cannot drive the car for 28 days without the warning light turning on.
Step-by-step explanation:
Since the car uses 0.6 gallons per day, and Diego's family has been driving the car for 28 days, that means the total amount of fuel used is [tex]0.6*28=16.8[/tex] gallons. To determine whether the warning light will be on or not, subtract the total amount of fuel - 18 gallons - by the amount of fuel already used. If the difference is greater than 1.5, that means the warning light will not come on. If the difference is less than or equal to 1.5, that means the warning light will come on. [tex]18 - 16.8 = 1.2[/tex], since 1.2 gallons is less than 1.5 gallons, that means Diego's family cannot drive the car for 28 days without the warning light turning on.
Answer:
no because the remaining fuel will be 1.2 gallon therefore the warning light will turn on
Step-by-step explanation:
18 gallon
0.6 per day
28 × 0.6 = 16.8
18 - 16.8 = 1.2

TWO points A and B on a plan represent two localities 12 m apart. Given that the segment AB is 6 cm long, find the scale used to draw the plan.
Answer:
The scale used to draw the plan is 1: 200.
Step-by-step explanation:
Given that two points A and B on a plan represent two localities 12 m apart, to determine, given that the segment AB is 6 cm long, the scale used to draw the plan, the following calculation must be performed:
12 m = 12 cm x 100 = 1200 cm
1200/6 = 200
Therefore, the scale used to draw the plan is 1: 200.

Sophia's retirement party costs $2 ,plus an additional $3 for each guest she invites.What is the maximum number of guests there can be if Sophia can afford to spend a total of $35 on her retirement party?
Answer:
11
Step-by-step explanation:
Sophia can only have 11 guest max at the retirement party if she can only afford to spend $35.
Given: $2 cost of party
Needed: How many guests
$3 per guests multiplied by 11 guests is $33
add that to the original (given) cost of party the total is
$35
3 times 11=33
33+2=35
The class must raise at least 100$ to go on the field trip. They have collected 20$. Write an inequality to represent the amount of money (m) the class still needs to raise.
Answer: 20x < 100
subtract 20 from both sides
20 - 20 = 0
100 - 20 = 80
x < 80
Carlos and his family left for the amusement park at 8:35 Ask Your Teacher The trip took 1 hour 55 minutes. What time did they arrive?
Answer:Carlos and his family arrived at 10:30
Step-by-step explanation:
The time Carlos and his family left for the amusement park =8:35
Since The trip took 1 hour 55 minutes., we have to add it to the time they left for the amusement park to now the time they arrived
8: 35 =8 hrs 35minutes
1 hr 55 minutes
90 minutes
but 90minues is greater than 60 so we convert to hours and minutres by dividing by 60 giving us
90/60=1.5hrs=1hr 30mins
8¹ hrs 35minutes
1 hr 55 minutes
10hrs 30 minutes
Therefore, They arrived at 10:30

Which of the following statements have the same result? Explain each step in solving each one.
I. f(2) when f(x) = 3x + 4
II. f−1(4) when f(x) = 3x - 4 over 5
III. 3y − 6 = y + 10
Answer:
1). 10 2). 8/5 3). 8
Step-by-step explanation:
I. f(2) = 3(2) + 4
= 6 + 4
= 10
II. f(4) = 3(4) - 4/5
= 12 - 4/5
= 8/5
III). 3y - 6 = y + 10
2y - 6 = 10
2y = 16
y = 8

Answer:
Q= 114°
R= 37°
P= 29°
x= 37
Step-by-step explanation:
x + x-8 + 3x +3 = 180
5x -5 = 180
5x = 175
x= 37
R = x = 37°
p= x-8 = 37-8 = 29°
Q = 3x+3= 3×37+3 = 114°

A sample of 23 women athletes, aged 20 was taken. The systolic blood pressure of these women had an average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
Answer:
Step-by-step explanation:
average of 112 with a standard deviation of 3.3. Calculate a 90% confidence interval for the average systolic blood pressure of 20-year old women athletes.
From the above question
Number of samples = 23 , less than 30,
Hence, we find confidence interval using t score
Confidence Interval using t score =
Mean + t score × standard deviation/√n
Step 1
We find the degree of freedom
= N - 1
= 23 - 1
= 22
