USING SIMILAR TRIANGLES IN INDIRECT MEASUREMENT If the shadow of a tree is 14 m long and the shadow of a person who is 1.8 m tall is 4 m long, how tall is the tree? Which of the following proportions could not be used to solve the problem? 14/1.8 = x/4 x/1.8 = 14/4 x/14 = 1.8/4

Answers

Answer 1

Answer:

14/1.8 = x/4

Step-by-step explanation:

Using similar triangles,

height of man/length of man's shadow = height of tree/length of tree's shadow

1.8/4 = x/14

x/14 = 1.8/4

If we cross-multiply, we have

1.8 × 14 = x × 4

dividing both sides by 4 and 1.8,we have

14/4 = x/1.8

x/1.8 = 14/4

So, the two expressions we have are

x/14 = 1.8/4 and x/1.8 = 14/4.

So, the answer is 14/1.8 = x/4 since the product 1.8 × 14 = x × 4 cannot be expressed in the given ratio.

Do you think two students who made no computation errors would get different values for this numerical expression> explain (4x35)+(36x8

Answers

Answer:

Yes, they would get different values

Step-by-step explanation:

Given

[tex](4 * 35) + (36 * 8)[/tex]

Required

Would there be different value for the expression?

From the question, we understand that both students made no computational errors. This doesn't mean that the students cannot make other errors.

For instance, the expression can be solved (wrongly) in the following ways;

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 140 + 36 * 8 \to 176 * 8 = 1408[/tex]

[tex](4 * 35) + (36 * 8) \to 4 * 35 + 36 * 8 \to 4 * 71 * 8 \to = 2272[/tex]

While the correct solution is:

[tex](4 * 35) + (36 * 8) \to 140 + 288 =428[/tex]

Hence, it is possible for two students to get different values

Answer:

=z ^(-11) + ^(-15)

= z ^ -26

Answer:

z^-11 times z^-15 = z^-26

Step-by-step explanation:

According to exponential properties, multiplying two numbers that have exponents with the same bases should be added.

Negative exponents mean to go from a^-x to 1/a^x.

Using these properties, we evaluate the expression.

Both terms have the same base, z, so we can go ahead and add the exponents.

-11 + -15 = -26

z^-11 * z^-15 = z^-26

Because the instructions specifically say to leave it in z^n form, our answer is z^-26.

Answers

Answer:

the answer is 9.

Step-by-step explanation:

The total stimulations in which all three elevators are working is 12(option d) by the concept of data representation.

What is data representation?

Data Representation: A method for analyzing numerical data is data representation. Data representation is used to create a diagram that shows the connections between facts, ideas, information, and concepts. It is a fundamental learning technique that is clear-cut and uncomplicated. The data type in a particular domain is always what determines it. There are many various styles and sizes of graphical representations.

According to the given data:

A building has 3 elevators.

The following set of random numbers represents 20 stimulations of the elevators, with 0, 1 representing the broken elevator and 2,3,4,5,6,7,8and 9 representing a working elevator.

Stimulation data:

931 188 763 841 559 144 652 277 653 673 404 396 011 843 599 797 414 761 273 844

Now, as we observe from the given data, the stimulation in which all three elevators are working are-

763,559,652,277,653,673,396,843,599,797,273,844a total of 12 stimulations.

Thus, the total stimulations in which all three elevators are working is 12

Hence, option d is correct.

Since there is no given median as the amount of numbers is even, find the number in between the 2 middle numbers, in this case, the number would be 12, as it is in between 11 and 13.

To find Q1 and Q3, you need to find the first and third median, which would be 5 and 43. To find the IQR, you need to subtract Q3 from Q1, which would give you 38 in this equation
