Answer: 148.5 miles
Step-by-step explanation:
450/50 gals= 9 miles can be driven for every 1 gallon.
Since we now know that our car uses 1 gallon of gas for every 9 miles we drive, we can now multiply the 9 miles with the 16 1/2= 16.5. So 16.5x9=148.5.
With our 16 1/2 gas tank, we can travel at least 148.5 miles before running out of gas.

The measure of DE is triangle ABE is similar to ACD is 9units
Similarity theorem of triangleFor triangles to be similar, the ratio of their sides must be equal to the constant called he scale factor.
From the given diagram;
AB/AE = AC/AD
20/15 = 32/15 + DE
Solve for DE
4/3 = 32/15+DE
4(15+DE) = 3(32)
15+DE = 3(8)
DE = 24 - 15
DE = 9
Hence the measure of DE is triangle ABE is similar to ACD is 9units

Answer: 19.62 * 10^7 cm
Step-by-step explanation:
Let a and b be rectangle sides.Area = a * bPerimeter = a + b + a + b = (a + b) * 2a = 9.2 * 10^7 cm
Area = 5.612 * 10^14 cm^2
Find: Perimeter - ?
Area = a * bb = Area / ab = (5.612 * 10^14) / (9.2 * 10^7) = 0.61 * 10^7 cm
Perimeter = (a + b)*2Perimeter = (9.2 * 10^7 + 0.61 * 10^7) * 2 = (9.2 + 0.61) * 10^7 * 2 = 9.81 * 2 * 10^7 = 19.62 * 10^7 cm

PLEASE HELP IM SO CONFUSED
Answer:
Lake Carters, Lake Amistad, Lake Alamo
Step-by-step explanation:
Starting with lake Alamo:
current level: 1,080
Full pool: -48.5
This indicates that the level is currently 48.5 feet below a full pool
Therefore, the level of it as a full pool is 1,080 + 48.5, or 1,128.5 feet
Lake Amistad:
Current Level: 1,038
Full pool: -7.1%
This indicates that the level is currently 7.1% below a full pool
subtract 7.1% from 100%
100-7.1=92.9
Percent formula:
P% * X = Y
P = 92.9
Y = 1038
X = 1038 / 92.9%
X = 1117.33
Full pool = 1117.33
Lake Carters
Current level: 1078
Full pool: + 60/13
This indicates that the level is currently 60/13 above a full pool
60/13 = 4.62
1078 - 4.62 = 1073.38
full pool = 1073.38
So, the order is Lake Carters, Lake Amistad, Lake Alamo

a. To solve for the greatest common factor (GCF), we can determine the prime factors of 6, which is 2 and 3. Then for the other number, we can do the exact same thing. The prime factors of 8 are 1, 2, and 4. When matching the all the prime factors together, we notice that 2 is in both the prime factors.
This means that the GCF of 6 and 8 is 2.
b. To factor the GCF of 6 and 8, we can use the prime factors of both 6 and 8. That means:
6 + 8 = 2 × (3 + 4).

Suppose the heights of the members of a population follow a normal
distribution. If the mean height of the population is 72 inches and the
standard deviation is 3 inches, 99.7% of the population will have a height
within which range?
A. 63 inches to 81 inches
B. 66 inches to 78 inches
C. 60 inches to 84 inches
D. 69 inches to 75 inches
The option (A) 63 inches to 81 inches is correct after using the empirical Rule.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
We have:
The mean height of the population is 72 inches and the standard deviation is 3 inches, 99.7% of the population will have a height
99.7% of data observed following a normal distribution lies within 3 standard deviations of the mean.
The lower range = 72 – 3(3) = 63 inches
The upper range = 72 + 3(3) = 81 inches
Thus, the option (A) 63 inches to 81 inches is correct after using the empirical Rule.

The person is lifting a heavy box using a lever what is the purpose of the lever in the situation?
====================================
[tex]\large \sf \underline{Problem:}[/tex]
The person is lifting a heavy box using a lever what is the purpose of the lever in the situation?
====================================
[tex]\large \sf \underline{Answer:}[/tex]
to reduce the force needed to lift the box and change the direction of the force.
====================================
[tex]\large \sf \underline{Explanation:}[/tex]
1. "A lever consists of a rigid bar that is able to pivot at one point. This point of rotation is known as the fulcrum. A force is applied at some point away from the fulcrum (typically called the effort)."
By this definition, we know that force is needed to lift an object using a lever.
2. "When the input and output forces are on opposite sides of the fulcrum, the lever changes the direction of the applied force. This occurs only with first-class levers. When both the input and output forces are on the same side of the fulcrum, the direction of the applied force does not change"
For example, on a sew saw, if a force is applied on one end, you on the other side/end would go up, meaning a change in direction.
3. Lastly, we know a lever is typically used to reduce work, in other words, the force needed to move something.
Basically, if we were to put a lever into an equation:
reduced force + change in direction = lever
(the expection) unless load and force are on the same side, there will be no change in direction.
For example, if you and your friend sit on the same side of a sew saw, the sew saw would not go up or down, meaning no change in direction.
So if not stated otherwise you can assume the load and force are on opposite sides. The purpose of a lever in that situation would be to reduce the force needed to lift the box and change the direction of the force.
*While reading my explanation, it may be helpful to look up a diagram containing a lever, with a load, fulcrum, and applied force.

A square is shown below. Which expression can be used to find the area, in square units, of the shaded triangle in the square
Answer:
1/2 × 6 × 6
Step-by-step explanation:
the triangle takes up half of the square
the area of a square = side length²
side length = 6
so area of square = 6² = 6 × 6
because the triangle takes up half of the square
the area of the shaded triangle would = 1/2 × 6 × 6

Write the measure in degrees.
Hi Student!
Looking at the question, we are given a fraction that has a pi symbol. We learn in trigonometry that a whole circle is made up of 2 * pi and we know that a circle is 360 degrees. That means that just having pi means that we have 180 degrees.
Therefore, looking at the fraction that was given to us, we can basically interpret it as 180 degrees / 4. That will give us a solution of 45 degrees which is our final answer.
Answer:
[tex]45^{\circ}[/tex]
Step-by-step explanation:
[tex]\dfrac{\pi}4 = \left(\dfrac{\pi }{4} \times \dfrac{180}{\pi} \right)^{\circ} = \left( \dfrac{180}4 \right)^{\circ} = 45^{\circ}[/tex]

What is the slope of the line given by the equation? (Enter your answer as a decimal if necessary)
y= 2.25x+ 2.44
Answer:
slope = 2.25
Step-by-step explanation:
This equation is written in slope-intercept form, which has the general structure: y = mx + b.
In this form, "m" = slope and "b" = y-intercept.
Therefore, the slope is 2.25 since it is replacing the "m" variable.
