Answer: 8250 or 8.25x10^3 (in standard form)

Step-by-step explanation: Step1 - Do each of the brackets first so, (2.5x10^2) = 250 because you are moving the decimal point up by 2 units (x100 = x10^2).

Step2 - apply the same onto the other bracket so, (3.3x10^1) = 33 because you are moving the decimal point up by 1 unit (x10 = x10^1).

Step3 - because the brackets are next to eachother without any signs in between them we apply multiplication so, 250 x 33 = 8250. Note: you can either leave your answer like this or put it back into standard form depending on what the question asks you to do.

If asked to put the answer 8250 back into standard form then you would get 8.25 x 10^3 remembering the number infront of the multiplier has to be between 1 and 10.

Hope this helps!

How do you solve 2z-31=-9z+24

Vaselesa [24]

Answer:

2z-31 = -9z+24

First, combine like terms: 11z = 55

Then, divide both sides by 11: 11z/11 = 55/11

Simplify: z=5

Answer:

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

Step-by-step explanation:

We need to write the expression that uses the associative property to make it easier to evaluate: $14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property of multiplication states that: $a(b\textbf{.}c)=(a\textbf{.}b)c$

So, For the given expression:

$14(\frac{1}{7}\textbf{.}\frac{2}{5} )$

The associative property will be:

$(14\textbf{.}\frac{1}{7})\frac{2}{5}$

So, Option C is the correct option.

How would you find the area or perimeter of this shape?

Fittoniya [83]

The perimeter of a given shape implies the sum of all its sides. While the area of a given shape is the total value of space it would cover on a 2-dimensional plane.

The perimeter of the shape is 104 cm.

The area of the shape is 640 $cm^{2}$ .

The perimeter of a given shape implies the sum of all its length of sides., such that the value of each individual side is summed to a total value.

The area of a given shape is the total value of space it would cover on a 2-dimensional plane. The area of shapes depends on the type of shape.

In the given question, the given shape has 12 sides. Some of these sides can sum up to a given length as shown in the diagram.

So that;

perimeter = 2 + 32 + 10 + 10 + 2 + 32 + 8 + 8

= 104 cm

Thus, the perimeter of the shape is 104 cm

ii. The area of the shape = length x width

= 32 x 20

= 640 $cm^{2}$

Therefore, the area of the given shape is 640 $cm^{2}$ .

Meteorologists look for weather trends across US states in the same geographical region. Kentucky and Illinois share a border. T

olya-2409 [2.1K]

The average annual temperatures (°F) from 1991 to 2000 for Kentucky were 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.

We have to evaluate the measures of center.

Firstly, we will calculate the mean.

Mean = (Sum of all the observations)/ (Total number of observations)

Mean = $\frac{57.5+55.1+52.2+55.6+55.6+54.4+54.5+58.3+57.3+55.7}{10}$

= $\frac{556.2}{10}$

= 55.62

Now, we will calculate mode.

Mode is a statistical term that refers to the most frequently occurring number found in a set of numbers.

Consider the data 57.5, 55.1, 52.2, 55.6, 55.6, 54.4, 54.5, 58.3, 57.3, and 55.7.

Mode = 55.6

Now, we will calculate the median.

Firstly, we will arrange in the ascending order.

52.2, 54.4, 54.4,55.1 ,55.6, 55.6, 55.7, 57.3, 57.5, 58.3

Since there are 10 terms.

Median = $\frac{n}{2}$ th observation

Median = 5th observation.

Since, the 5th observation is 55.6.

Therefore, the median is 55.6
