3.03 Quiz: Area of Triangles

Answer:

144

Step-by-step explanation:

2( 1/2 × 3 × 4 ) + ( 11 × 5) + ( 11 × 4 ) + ( 11 × 3)

= 12 + 55 + 44 + 33

= 144

Answer:

13 inches, 11 + t inches.

Step-by-step explanation:

1 hour 1 inch, so after 2 hours, the snow is 11 + 1*2 = 13 (inches).

After t hours, the snow is 11 + 1*t = 11 + t (inches).

Answer:

16.81

Step-by-step explanation:

P = 4a.

then the length of a side is 16.4 /4 = 4.1.

A = a * a = 4.1 * 4.1 = 16.81

Answer:

45.1 cubic inches

Step-by-step explanation:

16.4 divided by 4 is 4.1 and 4.1 multiplied by 4.1 is 45.1.

Step-by-step explanation:

out of the first equation we get

x = 2y - 3z - 1

this we use in the second equation

-3(2y - 3z - 1) + 6y - 9z = 3

-6y + 9z + 3 + 6y - 9z = 3

0 = 0

this is the same equation as the first one, just multiplied by -3.

and we see the third equation is again the same one as the first just multiplied by 2.

so, there are infinite solutions.

this has not a single solution, as in the end this is just one equation with 3 variables.

Answer:

Slope: 2

The slope how much y increases when x increases by 1.

Step-by-step explanation:

1. Find the difference between both y-coordinates. (6)

2. Find the difference between both x-coordinates. (3)

Divide the difference between y and x. y/x=2

The slope is 2.

Answer:

The slope of line that passes through the points (2, -4) and (5, 2) is 2.

Step-by-step explanation:

Here's the required formula to find slope line :

[tex]{\longrightarrow{\pmb{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}}[/tex]

As per given question we have provided that :

[tex]\begin{gathered}\footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf y_2 = 2\\& \sf y_1 = - 4\\ & \sf x_2 = 5\\ & \sf x_1 = 2\end{cases} \end{gathered}[/tex]

Substituting the values in the formula to find slope line that passes through the points :

[tex]\begin{gathered}\qquad{\longrightarrow{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{(2) - ( - 4)}{5 - 2}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{2 + 4}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = \dfrac{6}{3}}}}\\\\\qquad{\longrightarrow{\sf{m = 2}}}\\\\\qquad{\star{\underline{\boxed{\sf{\pink{m = 2}}}}}} \end{gathered}[/tex]

Hence, the slope of line that passes through the points (2, -4) and (5, 2) is 2.

Answer:

9.5%

Step-by-step explanation:

90.5% is the amount of flights that arrive on time, out of 100 so to find out the rest you have to minus 90.5 by 100.

90.5-100 = 9.5

Step-by-step explanation:

So basically its 420x420 which is 176400 which applies to all of these.

SO insert 1600 into Data Set 1.

For Data set II will be 69x69=4761

That is all you need. STAY SAFE!

Answer:

ok so first we have to find out how much each one increaces so llets just subtract the terms

3/4-2/5=0.35 so each time they add 0.35 so the nth term would be

2/5+0.35(n-1)

The function value of (m × n)(7) is: C. 0.

To find the value of a function, plug in the given value of x and simplify.

Given:

m(x) = x - 7

n(x) = 1/x + 7

Find (m × n)(7)

(m × n)(7) = (x - 7)(1/x + 7)

Plug in x = 7

(m × n)(7) = (7 - 7)(1/7 + 7)

(m × n)(7) = (0)(1/7 + 7)

(m × n)(7) = 0

Therefore, the function value of (m × n)(7) is: C. 0.

percentage, a relative value indicating hundredth parts of any quantity.

Given that  daily value of dietary fiber is 25g.

You only ate 80% of your daily value of dietary fiber.

We have to find the amount of dietary fiber in grams you eat .

To find this we have to find the value of 80 percentage of 25.

Convert 80 % to the decimal value by dividing 80 with 100.

80/100×25

Eighty by hundred times of twenty five.

Exact Answer:   2*sqrt(5)

Approximate Answer:  4.4721

====================================================

Explanation:

Original set = {1,3,4,5,7}

Square each value to get {1,9,16,25,49}. This is the list of squares.

Add up those squares: 1+9+16+25+49 = 100

Next, divide that over n = 5 which is the number of items in the set

100/n = 100/5 = 20

The value 20 is the mean of the list of squares above.

Lastly, apply the square root to get sqrt(20) = sqrt(4*5) = sqrt(4)*sqrt(5) = 2*sqrt(5)

This approximates to roughly 4.4721

--------------------

Side note: The term "root mean square" is often abbreviated to "RMS".

If we reversed the order of the three words, then we get "square mean root". In this reversed order, we see that the squaring operation is done first, then the mean next, and finally the square root is done last.

The value of the root mean square which is having sets of 1, 3, 4, 5, and 7 is 4.472.

It is the square root of the mean square, which is the arithmetic mean of the squares of the group of values.

The formula of root mean square is given as

[tex]\rm X_{RMS} = \sqrt{\dfrac{x_1^2+x_2^2+x_3^2+....+x_n^2}{N}}[/tex]

N be the total number of observations.

The sets 1, 3, 4, 5, and 7.

Then the root mean square will be

[tex]\rm X_{RMS} = \sqrt{\dfrac{1^2+3^2+4^2+5^2+7^2}{5}}\\\\X_{RMS} = \sqrt{\dfrac{1+9+16+25+49}{5}}\\\\X_{RMS} = \sqrt{\dfrac{100}{5}}\\\\X_{RMS} = \sqrt{20}\\\\X_{RMS} = 4.472[/tex]

Answer:

The answer is C I can't explain it but maybe someone else can, I'm sorry.

Answer:

n > 2 or n < 6

Step-by-step explanation:

3 - | 4 - n | < 1

Let's move 3 to the other side of the equation:

- | 4 - n | < 1 - 3

- | 4 - n | < -2

Both sides of the equation are negative, so we can simplify by multiplying them with -1:

(- | 4 - n | < -2*-1

| 4 - n | < 2

We cannot get rid of the module because it's not for a single number and we dont know what n is equal to but there is a rule that we can use to remove the module:

- if | x | < a and a > 0 then -a < x < a. So if we use it we get the following:

- 2 < 4 - n < 2

These are two equations, separate and solve them separately

4 - n < 2

- n < 2 - 4

- n < -2

n > 2 (< turns into > because we changed sign)

and

- 2 < 4 - n

4 - n > -2

-n > -2 - 4

n < 6 (we change the sign of the numbers so the equation changes too)

So after solving the two equation we get the answers
