Answer:

The probability of choosing a green shirt is 20%=1/5=.2

Step-by-step explanation:

find the total amount = 10

Find the total of question (probability of choosing green) = 2

set as a fraction:

Numerator = amount needed (2)

Denominator = all things/objects involved (10)

PS*

With probability there is a good chance the answer is going to be less than 1 or 100%, knowing that can help to tell which number goes in what place of the fraction

ex:

10/2=5=500% (this can't be the answer)

So Flip it 2/10=.2=20% (This seems more of a reasonable answer)

The correct statement about the area and perimeter of Triangle 2 is true are,

⇒ The perimeter is 4.1 times the perimeter of Triangle 1, and the area is 16.81 times the area of Triangle 1.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.

Now, We get;

The Triangle 1 is dilated by a scale factor of 4.1 using the origin as the center of dilation to create Triangle 2.

Hence, The perimeter of triangle 2 is 4.1 times the perimeter of Triangle 1.

And, We know that;

Area of triangle = 1/2 x Base x Height

So, The area of triangle 2 is 16.81 times the area of Triangle 1.

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer: C. 120 mi.

Step-by-step explanation:

To get the answer C you take the constant rate which is 40 and multiply it by the amount of hours which is 3. Hope this helps!

Answer:

C. 120 mi.

Step-by-step explanation:

If he is constantly going 40 miles per hour. That means every hour, he goes 40 miles. So if he drives 3 hours, he would drive 120 miles because 40 miles +40 miles+40 miles=120 miles. Aka 40 times 3 to get 120 miles.

Step-by-step explanation:

Both have an odd amount of numbers, meaning there is a perfect middle.

Answer:

Sure, I'll explain the cosine rule and sine rule in simple terms:

The cosine rule (also known as the law of cosines) is used to find the length of a side or the measure of an angle in a triangle given the lengths of the other sides and the angle between those sides. It states that c^2 = a^2 + b^2 - 2ab cos(C), where c is the length of the side opposite angle C, and a and b are the lengths of the other two sides.

Here's an example of how to use the cosine

Suppose we have a triangle with sides a=6, b=8, and an angle between them c=45 degrees. We want to find the length of the remaining side of the triangle, side a.

Using the cosine rule:

a^2 = b^2 + c^2 - 2bc * cosA

where A is the angle opposite side a, we can plug in our values and solve for a:

a^2 = 8^2 + 6^2 - 2(8)(6) * cos(45)

a^2 = 64 + 36 - 96 * 0.707

a^2 = 10.56

a = sqrt(10.56)

a = 3.25 (rounded to two decimal places)

Therefore, the length of side a is approximately 3.25 units.

Step-by-step explanation:

j+47 = 55

j = 55-47

j = 8

Answer: 8

Step-by-step explanation:

Sum means addition so j is a number that equals 55 when added to 47. So what you do is subtract 47 from 55 to give you j.  55-47 is 8 so j is 8.

Answer:(number)=-5

Step-by-step explanation:

You can use simple logic in order to solve this equation.

An equation that has infinitely many solutions will have the same exact numbers on both sides

Example: 3x = 3x, it has infinite solutions because no matter what number you put, the equation will always be true

The solution for this equation is -5 because when -5x-19=-5x-19, no matter what number you put as a solution, it will be true.

Answer:

Strawberry= 3
Watermelon=3
Coconut=9
Orange=5

Step-by-step explanation:

Quite easy, you can use substitution

First look at the simplest row that can be solved by itself

row 2:

2strawberries +4 = 10

2 strawberries= 6

1 strawberry = 3

Row 3: Strawberry(3)+ orange=8

1 orange= 5

Rpw 4: 14= 1coconut +orange(5)

1 coconut= 9

Row 1: Coconut(9)+ watermelon+ coconut(9)= 21

2 coconut(18)= 21

1 watermelon = 3

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

Hope you understood the answer and I hope it helps you :)
