Answer:

10

Step-by-step explanation:

Correct me if I’m wrong it’s been a while but I think u add 3 + 3 + 2+ 2

Answer:

It is 10

Step-by-step explanation:

In order to do perimeter you need to add each corners value, in this case a to B is one side and A to D is another, in order to get from A to B you have to walk 3 units, so their is our first part, now for the second you need to walk from point a to point D which if you do it will be 4 units.

Now we have 2 numbers, 4 and 3, We still have the other side but it will be the same, so you will do 4+4 and 3+3, in this case it will be 8+6 so the answer should be 14. I might be wrong.

Answer:

[tex]A) 14.89~ units[/tex]

Step-by-step explanation:

[tex]AD=C=3.42~, AC=d=4.57, ~CD=a=4.39[/tex]

[tex]S=\frac{C+d+a}{2} =\frac{3.42+4.57+4.39}{2} =6.19[/tex]

[tex]Using ~ heron's~ formula:[/tex]

[tex]Area~ of ADC~is:[/tex]

⇒ [tex]\sqrt{s(s-c)(s-d)(s-a)}[/tex]

⇒ [tex]\sqrt{6.19(6.19-3.42)(6.19-4.57)(6.19-4.39)}[/tex]

⇒ [tex]\sqrt{6.19*2.77*1.62*1.8}[/tex]

⇒ [tex]\sqrt{49.9986}[/tex] ⇒ [tex]7.071[/tex]

[tex]Area ~of ~ ABD ~is:[/tex]

⇒ [tex]\sqrt{s(s-d)(s-b)(s-a)}[/tex]

⇒ [tex]\sqrt{8.35(8.35-7.84)(8.35-3.42)(8.35-5.44)}[/tex]

⇒ [tex]\sqrt{8.35*0.51*4.93*2.91}[/tex]

⇒ [tex]\sqrt{61.0937}[/tex] ⇒ [tex]7.816[/tex]

[tex]So, Area ~ of ~quadrilateral~ ABCD ~ =[/tex]

[tex]A=Area ~of ~ADC+Area ~ of ABD:[/tex]

[tex]A=7.071+7.816[/tex]

[tex]A=14.89 ~units^2[/tex]

Answer:

Step-by-step explanation:

Answer:

72 square units

Step-by-step explanation:

you can use the Pythagorean Theorem; because we're dealing with a square then each side can be assigned the same variable, let's use 'a'

a² + a² = 12²

2a² = 144

a² = 72

a = [tex]\sqrt{72}[/tex]

[tex]\sqrt{72}[/tex] can be simplied as [tex]\sqrt{9}[/tex]·[tex]\sqrt{4}[/tex]·[tex]\sqrt{2}[/tex] which is 3·2·[tex]\sqrt{2}[/tex]

each side has a length of 6[tex]\sqrt{2}[/tex]

A = (6[tex]\sqrt{2}[/tex])² which is 6·6·2 or 72

Answer:

a(x) = √x+3

Answer:

b = 30°

Step-by-step explanation:

a + b + 90° = 180°

60° + 90° + b = 180°

150° + b = 180° ( subtract 150° from both sides )

b = 30°

Step-by-step explanation:

cos(57)=x/15

Answer:

If you mean 57 degrees then the answer is 8.1695...

If you mean 57 radians then the answer is 13.498...

Step-by-step explanation:

Isolate the x by multiplying 15 on both sides

15 x cos(57) = x

Answer:

Option D, I agree with neither Elena nor Lin

Step-by-step explanation:

The remaining part of the question is attached herewith

Solution

As we can see in the image  

ED is perpendicular to AB and BC is perpendicular to AB

Thus, as per the Pythagoras theorem,  

AC^2 = AB^2 + BC^2  

14^2 = 6^2 + BC^2

BC^2 = 196-36 = 160

BC = 12.649 OR 12.65

Hence, option D

I agree with neither Elena nor Lin

Answer:

4 buses

Step-by-step explanation:

There are 173 basketball fans

one bus can hold 46 fans

Hence the number of buses needed can be calculated as follows

= 173/46

= 3.76

= 4

Hence 4 buses are needed

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

We'll use this formula

a & b/c = (a*c + b)/c

to convert from a mixed number to an improper fraction.

Let's convert the first mixed number to an improper fraction

a & b/c = (a*c + b)/c

3 & 3/4 = (3*4 + 3)/4

3 & 3/4 = 15/4

Repeat the same idea for the second mixed number as well

a & b/c = (a*c + b)/c

3 & 1/3 = (3*3 + 1)/3

3 & 1/3 = 10/3

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

In short we have

Doing these conversions is useful to be able to multiply the values like so:

(15/4)*(10/3) = (15*10)/(4*3) = 150/12 = (6*25)/(6*2) = 25/2

Now use your calculator to find that 25/2 = 12.5

We can then say....

12.5 = 12 + 0.5 = 12 + (1/2) = 12 & 1/2

The answer is choice F) 12 & 1/2 square yards.

The graph for the inequality given is graph 1.

An inequality is a relation between two numbers or expressions that are not equal. It can show which of them is greater or smaller by using symbols like < or >. It can also be a statement of fact about the order relationship of quantities.

Given that an inequality, 2-(x+3) < 4 -2x, we need to determine its graph,

For the same solving the inequality,

2-(x+3) < 4 -2x

2-x-3 < 4 - 2x

Add x to both sides,

2-3 < 4-x

-1 < 4-x

Subtract 4

-1-4 > -x

x > 5

Since, the x is greater than 5 so the graph will be the numbers that greater than 5,

Hence, the graph is 1.
