Final answer:
The 72 feet high pole has a shadow that is 24 feet long, as determined by using proportional relationships between the heights and shadows of two similar triangular shapes formed by the poles and their shadows.
Explanation:
Given the first pole that is 24 feet high has a shadow that is 8 feet long, we can determine the ratio of the height to the shadow length. Since similar triangles have proportional sides, we can apply the same ratio to the second pole that is 72 feet high to find the length of its shadow.
Setting up the proportion, we have:
24 feet (height of first pole) / 8 feet (shadow of first pole) = 72 feet (height of second pole) / x (shadow of second pole).
To solve for x, we cross multiply to get
24 * x = 72 * 8.
Dividing both sides by 24, we get x = 24 feet.
Hence, the shadow of the 72 feet high pole is 24 feet long.
Is .634 an integer ??
No.
An integer is a whole number.
In the case of .634 (or 0.634), we see that it is not a whole number, as there is a decimal point, and numbers to the right of the decimal points.
hope this helps
No, because .634 is an odd number and odd numbers cannot be integers.

The first step is to figure out what angle DEB is equal to. Check out the attached image. I've marked this as angle y and it is shown in purple.
Note how the purple angle y and the orange 160 degree angle form a straight angle (180 degrees). So the two angles add to 180. Let's solve for y
(orange angle) + (purple angle) = straight angle
(angle CEB) + (angle DEB) = angle CED
y+160 = 180
y+160-160 = 180-160 ... subtract 160 from both sides
y = 20
----------------------------------
Now we can use this to figure out angle x. The three angles x, 115, and 20, combine to 180 degrees as they all glue together to form a straight angle. Let's solve for x:
x+115+y = 180
x+115+20 = 180 ...replace y with 20
x+135 = 180 ......... combine like terms
x+135-135 = 180-135 ...... subtract 135 from both sides
x = 45
Therefore, the final answer is 45

Dividing whole numbers if insulation can be installed at a rate of 1,400 square feet per hour and 29,400 square feet needs to be installed,how many hours will the job take?
It will take approximately 21 hours to install the insulation.
Explanation:To determine the number of hours it will take to install 29,400 square feet of insulation at a rate of 1,400 square feet per hour, we can use division. We can divide the total square footage by the rate of installation per hour:
Number of hours = Total square footage / Rate of installation per hour
Number of hours = 29,400 square feet / 1,400 square feet per hour
Number of hours = 21 hours
Therefore, it will take approximately 21 hours to install the insulation.

which unit is most appropriate to use to measure the volume of a bathtub
The most appropriate unit to measure the volume of a bathtub is liters.
When considering the volume of a bathtub, the most appropriate unit of measure would be liters. Milliliters are too small for such a large volume, and while gallons could be used, liters are more standard for this type of measurement in many parts of the world, including in scientific contexts.
For example, if we have a common bathtub that is 13.44 dm long, 5.920 dm wide, and 2.54 dm deep, we would calculate its volume in liters. Since a bathtub has a capacity similar to a large container, liters are an appropriate choice because they give a manageable number for the volume. In measuring smaller volumes, like that of a water balloon or a chemical solution in a lab, milliliters or a graduated cylinder may be used instead.

clara wants to run a total od 5 1/2 miles each lap around the track is 0.25 miles how many laps around the track does clara need to run to complete 5 1/2
Final answer:
Clara needs to run 22 laps around the track, at 0.25 miles per lap, to reach her goal of 5 1/2 miles.
Explanation:
The question is about calculating the number of laps Clara needs to run to cover a distance of 5 1/2 miles, with each lap being 0.25 miles long. To find the number of laps, we divide the total distance she wants to run by the distance of one lap.
Total distance Clara wants to run: 5 1/2 miles or 5.5 miles (converting 1/2 into decimal for easier calculation).
Distance of one lap around the track: 0.25 miles.
To find the number of laps, we perform the division:
5.5 miles ÷ 0.25 miles/lap = 22 laps.
Therefore, Clara needs to run 22 laps around the track to complete her goal of 5 1/2 miles.

An isosceles triangle has an angle that measures 80°. Which other angles could be in that isosceles triangle? Choose all that apply
In an isosceles triangle with an angle measuring 80°, the other two angles could be 50° each.
An isosceles triangle has two sides of equal length and two angles of equal measure. Since one angle measures 80°, the other two angles must be equal to each other. To find the measure of these angles, we subtract 80° from 180° (the sum of all angles in a triangle) and divide the result by 2. So, each of the other two angles in the isosceles triangle could be 50°.

The sum of the angles in any triangle is always [tex]\(180^\circ\).[/tex] Given that one angle measures [tex]\(80^\circ\)[/tex], we need to determine the possible configurations for the remaining angles.
Case 1: 80° is the vertex angle
If the [tex]\(80^\circ\)[/tex] angle is the vertex angle (the angle between the two equal sides), the remaining two angles must be equal. Let x be the measure of each of the remaining angles.

Comment on subtacting mixed numbers
Some folks find it convenient to subtract by adding. To find the difference between 3 1/4 and 6, they would start by adding 3/4 to make 4, then add 2 to make 6. Then they see the difference is 3/4 + 2 = 2 3/4.
Here, I chose to subtract 3 1/4 by subtracting 3, then subtracting 1/4. After subtracting 3 from 6, I get 3, from which I now need to subtract 1/4. It should be clear that taking 1/4 away from 3 will leave 2 3/4. (One of the units has been converted to 4/4 to make the subtraction of 1/4 possible.)

You have invested in three different stocks: Engineering Aces, Upton Clothiers, and Thompson Musical Instruments. Because you have diversified your stocks so well, the way they change is independent. The probabilities of the stocks changing in value by more than 10% in a given week are listed below.
P(E) = 19%
P(U) = 11%
P(T) = 6%
What is the probability that all three will change by more than 10% in the same week?
Answer:
answer is 0.001254.
Step-by-step explanation:
Given that you invested in 3 stocks of Engineering Aces, Upton Clothiers, and Thompson Musical Instruments.
Also given that each stock value is independent of the other.
Let E be the event changing in value by more than 10% in a given week for Engineering Aces,
U be the event changing in value by more than 10% in a given week for Upton Clothiers, and T be the event changing in value by more than 10% in a given week for Thompson Musical Instruments.
Given that P(E) = = 19%
P(U) = 11%
P(T) = 6%
probability that all three will change by more than 10% in the same week
= P(EUT)
= P(E) P(U) P(T) since three events are independent.
=0.19(0.11)0.06
= 0.001254
Final answer:
The probability that all three stocks, Engineering Aces, Upton Clothiers, and Thompson Musical Instruments, will change by more than 10% in the same week is calculated by multiplying their individual probabilities together, resulting in a probability of 0.1254%.
Explanation:
The question asks for the probability that all three stocks will change by more than 10% in the same week, given their individual probabilities.
To find this probability, since the changes in stocks are independent of each other, we multiply the probabilities of each event occurring together. The formula for the joint probability of independent events is P(E and U and T) = P(E) × P(U) × P(T).
Using the given probabilities:
P(E) = 19% or 0.19P(U) = 11% or 0.11P(T) = 6% or 0.06We calculate:
P(E and U and T) = 0.19 × 0.11 × 0.06
Which equals:
P(E and U and T) = 0.001254 or 0.1254%
Therefore, the probability that all three stocks will change by more than 10% in the same week is 0.1254%.

Enter your answer as a decimal in the box.
Answer:
-4.5
Step-by-step explanation:
the multiplication of 1.25(−3.6) is -4.5.
What are mathematics operations?
• A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Here, the given expression is :
1.25(−3.6)
Now after removing the bracket multiplication sign will apply :
1.25 x −3.6 = -4.5
Therefore, the multiplication of 1.25(−3.6) is -4.5.

Tracie rides the bus home from school each day. The graph represents her distance from home relative to the number of minutes since the bus left the school.
What does the slope of the graph mean?
Tracie’s bus travels towards her home at an average speed of mile per minute.
Tracie’s bus travels towards her home at an average speed of 2 miles per minute.
Tracie’s bus travels away from her home at an average speed of mile per minute.
Tracie’s bus travels away from her home at an average speed of 2 miles per minute.
Answer:
Tracie’s bus travels towards her home at an average speed of 1/2 mile per minute.
Step-by-step explanation:
The labels on the graph tell us that the independent variable, x, represents time in minutes, and the dependent variable, y, represents distance from home in miles.
Looking at the graph, we can see that the number of miles from home decreases by 1 for every two minutes. Since the distance is decreasing, this means that the bus is getting closer to home. Since it decreases by 1 mile every 2 minutes, this means that the speed is 1/2 mile per minute.
The answer is : A, Tracie's bus travels towards her home at an average speed of 1/2 mile per minute.

The domain of the function is (0, 7) years.
The function that represents the height of the tree is defined over the period during which the tree's height changes. Given that,
The tree starts growing at 0 years (the time when it is first planted). It grows for 4 years, reaching a height of 6 feet by the end of that period. After 4 years, the tree stops growing and remains at 6 feet for the remaining 3 years. After 7 years total (4 years of growth + 3 years of constant height), the tree is cut down.
The domain of the function that represents the height of the tree is the time interval from when the tree is planted until it is cut down.

Answer:
[tex]x \leq 40 / 0.25\\ x \leq 160\\[/tex]
Step-by-step explanation:
If the spending limit is $ 40 and making each beads costs $ 0.25, then the amount of accounts you must do multiplied by the manufacturing cost should not exceed $ 40.
Then the inequation that this restriction would represent is:
[tex]0.25x\leq 40\\[/tex]
Where x is the number of beads made.
This could also be written more specifically:
[tex]x \leq 40 / 0.25\\ x \leq 160\\[/tex]
Therefore the number of beads must be less than or equal to 160
