Answer: about 270
Step-by-step explanation:
If you look closely at 200 ml, you will see that there are 5 evenly spaced bars. This tells us that 200-300 ml is split by 20s. Counting the bars, you reach 260, but it goes almost halfway past it. Therefore, we get 270 since 270 is halfway past 260 and 280.

Suppose you start with a full tank of gas (18 gallons) in your truck. After driving 6 hours, you now have 8 gallons left. If x is the number of hours you have been driving, then y is the number of gallons left in the tank. At what rate is your truck using gas
Answers
Step-by-step explanation:
y is the number of gallons left in the tank.
x is the number of hours you have been driving
Rate of consumption of gas
= (18 - y / x)
= 5 / 3 gallon per hour
= 6.309 L / hr
The rate at which your truck is using gas is 5/3 gallons per hour.
What is rate at which your truck is using gas?The rate at which your truck is using gas is calculated as follows;
Given that after 6 hours of driving, you have 8 gallons left in the tank, we can set up the following equation using the two given data points:
(Initial gallons - Remaining gallons) / (Initial time - Time elapsed) = (Change in gallons) / (Change in time)
The equation becomes;
Rate = (18 gallons - 8 gallons) / (6 hours - 0 hours)
Rate = (18 - 8) / 6
Simplifying this equation, we get:
Rate = 10 / 6
Rate = 5 / 3
Therefore, the rate at which your truck is using gas is 5/3 gallons per hour.

Assuming that workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year, find the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.
Answers
Answer:
The probability is [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]
Step-by-step explanation:
From the question we are told that
Workers' salaries in your company are uniformly distributed between $15,000 and $40,000 per year
Generally the probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000 is mathematically represented as
[tex]P(\$20,000 < X \$35,000) = \frac{ 35000 - 20000}{ 40000 - 150000}[/tex]
=> [tex]P(\$20,000 < X < \$35,000) = 0.6[/tex]
Using the uniform distribution, it is found that there is a 0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.
An uniform distribution has two bounds, a and b.
The probability of finding a value between c and d is:
[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]
In this problem, uniformly distributed between $15,000 and $40,000, hence [tex]a = 15, b = 40[/tex].
The desired probability is:
[tex]P(20 \leq X \leq 35) = \frac{35 - 20}{40 - 15} = 0.6[/tex]
0.6 = 60% probability that a randomly chosen worker earns an annual salary between $20,000 and $35,000.

Express the volume of the box as a polynomial function in terms of x problem. Squares of 2x by 2x units are cut out of each corner. Express the volume of the box as a polynomial in terms of x.
Answers
Answer:
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³
Step-by-step explanation:
The volume of any box is:
a * b * h where a is the length, b is the wide and h is the height
Assuming we have cardboard of dimensions: l * w
l - 2*x will be length of the box and
w - 2*x will be wide of the box
h = x the height, then:
V(x) = ( l - 2*x ) * ( w - 2*x ) * x
V(x) = [ ( l*w - 2*l*x - 2*w*x + 4*x² ] * x
V(x) = l*w*x - 2*l*x² - 2*w*x² + 4*x³

A plan traveled for a total of 2,773 miles over the course of 8 hours. Heading south, the plan traveled at an average speed of 344 miles per hour and heading west. It traveled at an average speed of 351 miles per hour. For how many hours was the plane heading south?
Answers
Answer:
5 hours
Step-by-step explanation:
Let s and w represent hours spent traveling south and west, respectively. The problem statement tells us ...
s + w = 8 . . . . . . total trip time
344s + 351w = 2773 . . . . total mileage (using d = s·t)
By Cramer's rule, we can find the value of s as ...
s = (1(2773) -351(8))/(1(344) -351(1)) = -35/-7 = 5
The plane was heading south for 5 hours.

Is a temperature of 35 degrees Fahrenheit as cold as a temperature of -35 degrees Fahrenheit?
Answers
Answer:
Step-by-step explanation:
Definitely not. -35 degrees is far below freezing (+32 degrees). On the other hand, +35 degrees is very warm indeed.
No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.
We have temperature in degrees Fahrenheit.
We have to investigate - " Is a temperature of 35 degrees Fahrenheit as cold as a temperature of -35 degrees Fahrenheit ".
What is the formula to convert Fahrenheit to degrees Celsius ?The formula is -
(°F − 32) × 5/9 = °C
According to the question -
Assume that -
A = 35°F = 1667 °C
B = -35°F = -37.2222 °C
The temperature 35°F represents very very high temperature (hot) whereas the temperature -35°F represents very very low temperature (cold).
Hence, No, the temperature of 35 degrees Fahrenheit is not as cold as a temperature of -35 degrees Fahrenheit.

In May 1998, forest fires in southern Mexico and Guatemala spread smoke all the way to Austin. Those fires consumed forest land at a rate of 25200 acres/week. On the average, how many square meters of forest are burned down every minute
Answers
Answer:
On average the size of the area of the forest burnt down every minute is 10117.14 m²
Step-by-step explanation:
The given parameters are;
The rate consumption of forest land by the fire = 25200 acres/week
Therefore, we have;
The number of minutes in one week = 60 × 24 × 7 = 10080 minutes
Therefore;
The rate consumption of forest land by the fire per minute = 25200/10080 acres/minute = 2.5 acres/minute
The number of square meters in one acre is given as follows;
1 acre = 4,046.856 m²
Therefore;
2.5 acres/minute = (2.5 × 4,046.856 m²/(1 acre)) acres/minute = 10117.14 m²/minute
Which give;
The rate consumption of forest land by the fire= 10117.14 m²/minute.
The rate of the fire consumption of the forest is 10117.14 m²/minute.

balloon from a height of 5,184 ft. If the
equation for height as a function of time
is h(t) = -16t2 - initial height where t is
time in seconds and h(t) is height in feet,
how many seconds will it take for the
piece of rope to hit the ground?
Answers
Answer:
18 seconds
Step-by-step explanation:
Given the equation for height as a function of time expressed as
h(t) = -16t² - initial height, if initial height is 5,184ft, the expression will become;
h(t) = -16t² - 5,184
t is time in seconds
h(t) is height in feet
The height of the rope on the ground is zero. In order to calculate the amount of seconds it will take the piece of rope to hit the ground, we will substitute h(t) = 0 into the modeled equation as shown:
Since the body falls downwards (negative direction), initial height = -5184 ft
h(t) = -16t² - -(5,184)
0 = -16t² + 5,184
0+16t² = 5184
16t² = 5184
16t²/16 = 5184/16
t² = 324
t = √324
t = 18 seconds
Hence, it will take the rope 18seconds to hit the ground.

5.1 cm² approximately
Step-by-step explanation:

A lighter=π r² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=π(5cm)² (80°/360°) -1/2(5 cm)² sin 80°
A lighter=3.14*25cm²(80°/360°) - 12.5cm² sin 80°
A lighter=17.444…cm² - 12.31009... cm²
A lighter=5.13cm² approximately
Answer: =approx 5.13 cm²
Step-by-step explanation:
Lets find the area of the region that is blue ( dark blue+light blue)
S= pi*r^2/360*80=pi*25*2/9=pi*50/9
The lighter region' s area is the S- S(triangle marked with dark blue)
The area of this triangle is r^2*sin(80°)/2= 25*sin(80°)/2=
=12.5*sin(80°)
So the required area Sreg= pi*50/9-12.5*sin(80°)=

Answers
Answer:
63%
Step-by-step explanation:
Given the following :
Average cholesterol level or mean (m) = 194
Standard deviation (sd) = 15
what percentage of children have a cholesterol level lower than 199?
P(X < 199)
Assume a normal distribution :
Find the z-score :
Z = (score - mean) / standard deviation
Score = 199
Z = (199 - 194) / 15
Z = 5 / 15
Z - score = 0.3333
P(Z < 0.33) :
Using the z - table ; 0.33 = 0.6293
P(Z < 0.33) = 0.6293
0.6293 * 100% = 62.93%
= 63% (nearest whole percent)
