Step-by-step explanation:

we need to make two rectangles.  

one that is 13.1 Km  X  (9.3-4.2) Km

13.1 * 5.1 = 66.81

the next box is 4.2 X (13.1-8.1)

4.2*5 = 21

area total = 21 + 66.81 = 87.81[tex]Km^{2}[/tex]

Answer:

The answer is 5=x (he is able to buy 5 videogames)

Step-by-step explanation:

First, you need to put this into an equation format with a variable (x) for the videogames. Here is what the equation should look like: 75 = 35 + 8x

75 being the total amount of money he has to spend, 35 being what he had to spend or knows he will spend on the controller, and the 8 is for each videogame. We put an 'x' behind the 8 to signal that we don't know how many games he can buy. So, then we need to solve the equation.

75=35+8x

-35 on both sides

So, 40=8x, then you divide by 8 to get x by itself

5=x

The 'x' in this equation is how many videogames he is able to buy. The way you could check your work is if you plugged 5 back into x. What I mean is this: 35+8(5) needs to equal 75, and it does, so you're good!

Answer:

C. Full of

Step-by-step explanation:

Ous is defined as full of or possessing. An example of ous used as a suffix is in the word "contemptuous," which means full of contempt. Moreover, how does the suffix ous change a word? Adding the suffix -ous A suffix is a letter or a group of letters that can be added to a word to change its meaning.

I hope this helps :3

-ous means "full of".

Answer:

$1.26

Step-by-step explanation:

So you just have to find 2.25% of 56.

To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:

2.25% of 56

Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:

2.25% × 56

Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.

2.25% = 0.0225

And now you have:

0.0225 × 56

Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.

But once you multiply 0.0225 × 56, you get an answer: 1.26

Select all true statements

First, calculate the total observed frequency;

[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]

[tex]Total = 90[/tex]

(a): Relative frequency of 4 is 2/9

Relative frequency is calculated by:

[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]

For roll 4

[tex]Observed\ frequency = 20[/tex]

So, the relative frequency is:

[tex]RF = \frac{20}{90}[/tex]

Simplify

[tex]RF = \frac{2}{9}[/tex]

(a) is true

(b): Experimental probability of 3 greater than its theoretical probability

The experimental probability is its relative frequency;

For roll 3

[tex]Observed\ frequency = 14[/tex]

The experimental probability is:

[tex]Pr = \frac{14}{90}[/tex]

Simplify

[tex]Pr = \frac{7}{45} = 0.156[/tex]

To calculate  the theoretical probability, w have:

[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space

[tex]n(S)= 6[/tex]

[tex]n(3) = 1[/tex] --- number of times 3 occur

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.

(b) is false

(c): Experimental probability of 2 greater than its theoretical probability

Using the explanations in (b), we have:

For roll 2

[tex]Observed\ frequency = 16[/tex]

The experimental probability is:

[tex]Pr = \frac{16}{90}[/tex]

Simplify

[tex]Pr = \frac{8}{45} = 0.178[/tex]

To calculate the theoretical probability, we have:

[tex]n(S)= 6[/tex]

[tex]n(2) = 1[/tex]

The theoretical probability is:

[tex]Pr = \frac{1}{6} = 0.167[/tex]

The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.

(c) is true

(d): Relative frequency of 5 is 2/13

For roll 5

[tex]Observed\ frequency = 12[/tex]

The relative frequency is:

[tex]RF = \frac{12}{90}[/tex]

Simplify

[tex]RF = \frac{2}{15}[/tex]

(d) is true

Answer:

a) P(0, 2), Q(4, 0)

b) Please find attached the plot of the points P and Q on a chart made with MS Excel

c) Please find the graph of the line that represent the function 4·x + 2·y = 8 for values of x from -2 to 3 made with the Insert Chart feature on MS Excel

Step-by-step explanation:

The given equation for the line is 4·x + 2·y = 8

a) The coordinates of P = P(0, _)

Therefore, the point 'P', which is the point where the variable y = 0, is the point the (straight line) graph intercepts the x-axis (the x-intercept)

When y = 0 from the given equation, we get;

4·x + 2·y = 8

At the point y = 0;

4·x + 2 × 0 = 8

x = 8/4 = 2

x = 2

∴ The coordinates of P = P(0, _) = P(0, 2)

Similarly, when x = 0, we get;

4·x + 2·y = 8

At the point x = 0;

4 × 0 + 2·y = 8

y = 8/2 = 4

y = 4

∴ The coordinates of Q = Q(_, 0) = Q(4, 0)

b) Rewriting the given equation in terms of 'y' gives;

y = (8 - 4·x)/2 = 4 - 2·x

y = 4 - 2·x

With the help of MS Excel, the points P and Q are plotted in the attached graph

c) The line of the graph of the function 4·x + 2·y = 8 for values of x from -2 to 3 can be added by Changing the Chart Type to 'Scatter with Smooth Lines and Markers' within MS Excel as presented in the included graph of the line.

The equation of the red graph is,

⇒ y = x² + 4

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The equation of blue graph is,

⇒ y = x²

Since, We have;

The red graph is 4 unit up from the blue graph.

Hence, The equation of the red graph is,

⇒ y - 4 = x²

⇒ y = x² + 4

Therefore, The equation of the red graph is,

⇒ y = x² + 4

Answer: it is 3 definitely

Step-by-step explanation:

There are 4 people and each are getting one drink for 1.50 and 3 tacos so it makes sense to do 4 ( 1.50 + 3x ) by the way x stands for the money for the tacos

Part B: 65

Part A: Since there are 30 students of the class and 17 are boys, there are 13 girls. 13/30 = 43.33 = 43%.

Part B: Since 43% of the class are girls, we do 150*0.43 for the whole 7th grade which is 64.5 which I rounded to 65.

Answer:

4 and 9

Step-by-step explanation:

here's how it should be:

(36÷4) - (36÷9)

9 - 4

5

Answer:

(36 ÷ 4) − (36 ÷ 9) = 5

Step-by-step explanation:

To solve, we need to find the quotient of 36 divided by each number listed:

 ║12 ⇒ 36 ÷ 12 = 3

 ║8 ⇒ 36 ÷ 8 = 4.5

 ║9 ⇒ 36 ÷ 9 = 4

 ║4 ⇒ 36 ÷ 4 = 9

So, which of these two numbers can you subtract from each other to get 5?

 ║We can subtract 4 from 9 to get 5.

Therefore, our answer should be:

 ║(36 ÷ 4) − (36 ÷ 9) = 5

Answer:

The first step is to determine the largest number that evenly divides the numerator and the denominator (also called the Greatest Common Factor of these numbers). In other words, what's the biggest number that goes into '2' (the numerator) and '4', the denominator?

Step 2. Once you've answered step 1 and realized that, for our fraction at least, the greatest number that evenly divides 2 and 4 is '2'. Now divide the top and the bottom by 2 to get your simplified fraction which is ½.

I hope this helps if you have any questions on my answer plz let me know Ty :3

Answer:

find the greatest common factor, then divide the bottom and the top, and you have that as your answer

Answer:

122degrees

Step-by-step explanation:

Since triangle BDC is a triangle, hence;

49 + 70 + <DBC = 180

<DBC = 180 - (70+49)

<DBC = 180 - 119

<DBC = 61

Since angle at the vertex is half the angle of its intercepted arc, then;

<DBC = 1/2 x

61 = 1/2 x

x = 61 * 2

x = 122degrees

Hence the measure of arcDC is 122degrees

log,8, = same as above

The expression  [tex]5log2-log4[/tex] is equivalent to  [tex]log8[/tex]  which is option c.

A logarithm answers the question "How many of this number do we multiply to get that number?" Example How many 2s must we multiply to get 8 that is 3.

Given,

[tex]5log2-log4[/tex]

= [tex]log2^5-log4[/tex]

Answer:

Discontinuity at (1, 7), zero at (-4/3 , 0)

Step-by-step explanation:

[tex]3x^{2} + x - 4[/tex] = (3x + 4)(x - 1) = 0

                        x = -4/3   or 1

But x = 1 makes f(x) undefined, so there is discontinuity at x = 1

and there is a zero at x = -4/3.

3x + 4 = 3(1) + 4 = 3 + 4 = 7

If you were to graph this function, then you would get the line y = 3x + 4 with a hole at (1, 7).   The line would cross the x-axis at (-4/3, 0) with discontinuity at (1, 7)
