Answer:
x = 3.8 + 53.6
Step-by-step explanation:
From the info that they gave you, you can tell that the original number is unknown, so that is x. Since Sushil is subracting 3.8, meaning, to get x, you're going to have to do the opposite which is........addition! So, to get x, you have to add 3.8, and 53.6. I hope I make sense!!
Write a real-world problem that can be solved using the equation 9+4x=21−2x.
1. you have to subtract 9 from both sides. 21-9= 12
2. you have to add 2x to both sides. 4x+2x= 6x
3. 6x divided by both sides =
4.x=2

7. The lifetime of a certain brand of tires is approximately normally distributed, with a
mean of 40,000 miles and a standard deviation of 2,500 miles under normal driving conditions.
Tire wear is greatly affected by road, weather and driver conditions along with proper
maintenance of the tires. A driver who aggressively accelerates or makes quick stops, for
example, will wear out a tire much more quickly. The brand carries a warranty of 33,000 miles
under normal driving conditions, i.e., the company will replace a tire if it wears out before this
mileage limit is reached.
Answer:
0.0025551
Step-by-step explanation:
Given that:
Mean (m) = 40000
Standard deviation (s) = 2500
P(x < 33,000) :
USing the relation to obtain the standardized score (Z) :
Z = (x - m) / s
Z = (33000 - 40000) / 2500 = - 2.8
p(Z < -2.8) = 0.0025551 ( Z probability calculator)
Probability of Tyre wagering out before mileage limit is reached = 0.0025551

solve the equation or inequality.
5t - 3 (7t + 1) < 93
Step-by-step explanation:
5t-3(7t+1) < 93
Remove the parentheses
5t-21t-3 < 93
-16t < 93+3
-16t < 96
Divide both sides by 16
-t<96/16
-t<6
t > -6
Answer: The inequality t < 6 is the correct answer.
Step-by-step explanation:
5t - 3 (7t + 1) < 93 <--- This is the original equation.
5t + (7t + 1) - 3 < 93 <---- Use commutative property.
16t - 3 < 93 <--- Simplify
16t - 3 + 3 < 93 + 3 <---- Add 3 to both sides,
16t < 96 <--- Simplify and do addition.
[tex]\frac{16t}{16}[/tex] < [tex]\frac{96}{16}[/tex] <--- Divide both sides by 16.
t < 6 <--- is the answer to the inequality.

A cork has a mass of 3 grams and a volume of 16 cm3
. Calculate the density.
Answer:
0.1875, or 3/16
Step-by-step explanation:
The formula for density is mass/volume.
I hope this helps :)
Answer:
[tex]{\boxed {\sf \frac{3}{16} \ g/cm^3}}[/tex]
or
[tex]\boxed {\sf 0.1875 \ g/cm^3}}[/tex]
Step-by-step explanation:
Density can be found by dividing the mass by the volume.
[tex]\rho= \frac{m}{v}[/tex]
The mass of the cork is 3 grams and the volume is 16 cubic centimeters.
[tex]m= 3 \ g\\v= 16 \ cm^3[/tex]
Substitute the values into the formula.
[tex]\rho = \frac{3 \ g }{16 \ cm^3}[/tex]
Divide.
[tex]\rho=\frac {3}{16} \ g/cm^3[/tex]
[tex]\rho=0.1875 \ g/cm^3[/tex]
The density of the cork is 3/16 or 0.1875 grams per cubic centimeter.

Duane recorded the temperature outside his window one morning. On the second day, the temperature went up 7 degrees. On the third day, the temperature went down 10 degrees. On the fourth day, the temperature went down 6 degrees, and it was 1°F. What was the temperature on the first day?
Answer:
The temperature on the first day was 10 °F.
Step-by-step explanation:
Let's find the temperature in every single step starting from the fourth day:
[tex]T_{4} = T_{3} - 6 F = 1 F[/tex]
[tex] T_{3} = 1 F + 6 F = 7 F [/tex]
Then, the temperature of the third day was 7 °F
On the third day:
[tex] T_{3} = T_{2} - 10 F = 7 F [/tex]
[tex] T_{2} = 7 F + 10 F = 17 F [/tex]
Hence, the temperature on the second day was 17 °F.
Now, on the second day:
[tex]T_{2} = T_{1} + 7 F = 17 F[/tex]
[tex] T_{1} = 17 F - 7 F = 10 F [/tex]
Therefore, the temperature on the first day was 10 °F.
I hope it helps you!

The data below represents the number of workouts each member of Big Muscles Gym attended last month. 4,5,7,7,7,8,10,11,11,13,13,144,5,7,7,7,8,10,11,11,13,13,144, comma, 5, comma, 7, comma, 7, comma, 7, comma, 8, comma, 10, comma, 11, comma, 11, comma, 13, comma, 13, comma, 14 Which box plot correctly summarizes the data?
Given:
The data values are 4, 5, 7, 7, 7, 8, 10, 11, 11, 13, 13, 14.
To find:
The box plot for the given data set.
Solution:
The data values are
4, 5, 7, 7, 7, 8, 10, 11, 11, 13, 13, 14
Divide these values in two equal parts.
(4, 5, 7, 7, 7, 8), (10, 11, 11, 13, 13, 14)
Divide each group again in two equal parts.
(4, 5, 7), (7, 7, 8), (10, 11, 11), (13, 13, 14)
Here,
Minimum value = 4
[tex]Q_1=\dfrac{7+7}{2}=\dfrac{14}{2}=7[/tex]
[tex]Median=\dfrac{8+10}{2}=\dfrac{18}{2}=9[/tex]
[tex]Q_3=\dfrac{11+13}{2}=\dfrac{24}{2}=12[/tex]
Maximum value = 14
It means, the starting point is 4 and end point is 14 of the box plot.
Box is lies from 7 to 12 and one line inside the box at 9.
Therefore, the box plot of the given data set is shown below.

9. Anna wants to take horseback riding lessons.
She is given $200 for her birthday to cover the
cost. She has to pay $20 for grooming supplies.
If the lessons are $30 an hour, how many lessons
can Anna take?
The answer is x = 6
Let us first define x to be the number of hours of riding lessons she can take.
X = Hours of lessons
Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:
200 - 20 - 30x = 0
Simplifying, we get
180 = 30x
x=6

Two years ago Juanita bought 2 shirts for $15 and last year she bought 4 shirts for $45. Assuming the prices will increase linearly, how much will 8 shirts cost Juanita this year?
Answer:
This year, Juanita will have to use $75.
Step-by-step explanation:
Because if 2 shirts is $15, 4 shirts will be $30. $45 is $15 more than $30, so the increase is $15. 2*4 is 8, so that will make it 15*4=60. 60+15=75.

What information can be used to compare linear relationships? Explain why.
Answer:the slope and the y intercept (you can tell there linear if the slope is the same and the y-intercepts are different).
Step-by-step explanation:
Answer:
Sample Response: Linear relationships can be compared using their initial values, or y-intercepts, and their rates of change, or slopes. Initial values can tell you which relationship started with a greater value. Comparing slopes can tell you which relationship is rising or falling faster.
Step-by-step explanation:
Rebecca already knew 1 appetizer recipe before starting culinary school, and she will learn 3
new appetizer recipes during each week of school. After how many weeks of culinary school
will Rebecca know a total of 43 appetizer recipes?
Answer:
14 weeks
Step-by-step explanation:
so from what we know she already learned one appetizer recipe so she needs to learn 42 more so what we need to do since it's three every week we need to multiply three until we are able to get 42 so three times 14 gets 42 so that means that the answer would be 14

Tom is going to turn little Quacker into roast duck! He goes to the grocery store to get some salt and pepper seasoning to his duck dinner. Salt costs .50 cents per scoop. Pepper cost .75 cents per scoop, and he wants to speand less that $5. He plans to bring home no more than 8 scoops of seasoning
Answer:
He can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper spent maximum.
Step-by-step explanation:
Given that:
The cost of salt = 50 cents / scoop =$ 0.5 / scoop
The cost of pepper =75 cents / scoop = $ 0.75 / scoop
Let he buys x scoops of salt and y scoops of pepper.
As he plans to bring home no more than 8 scoops of seasoning, so
[tex]x+y\leq8\cdots(i)[/tex]
The total cost of x scoops of salt and y scoops of pepper = 0.5x+0.75y
As he wants to spend less than $5, so
[tex]0.5x+0.75y<5 \\\\ \Rightarrow 50x+75y<500 \\\\\Rightarrow 2x+3y <20\cdots(ii)[/tex]
Here, [tex]x\geq 0, y \geq 0[/tex] and x,y are counting numbers.
On plotting the graph of equations (ii) and (ii), the possible solution is the integral values in the shaded as shown in the figure.
The maximum possible integral values, for expances less than $5, are (x,y)=(3,4), (4,3).
Hence, he can buy 3 scoops of salts and 4 scoops of pepper or 4 scoops of salts and 3 scoops of pepper to spent maximum.
