How can the area of this triangle be determined by forming a rectangle? Select from the drop-down menus to correctly complete the statements. Copy and rotate the triangle and place it next to the existing triangle to form a rectangle.

The length of the rectangle is (Choose: 4, 5, 8,or 10) units.

The width of the rectangle is (Choose:4, 5, 8,or 10) units.

The area of the rectangle is (Choose: 10, 16,20,or 25)square units .

The area of the triangle is half the area of the rectangle, so the area of the triangle is (Choose:10, 16, 20 or 25) square units.​

a: Using scale, divide the wing dimensions on the graph by 2 then multiply by 192cm

8.125/2 = 4.0625 x 192 = 780 cm

5/2 = 2.5 x 192 = 480 cm

Actual dimensions: 780 cm by 480 cm

Divide by 100 to convert to meters:

780/100 = 7.8 meters

480/100 = 4.8 meters

b: area of a triangle = 1/2 x base x height

area = 1/2 x 480 x 780 = 187,200 square cm

1/2 x 7.8 x 4.8 = 18.72 square meters

i did the dimensions in both cm’s and meters

Answer:

For A i would put 64 because its basically doing the total wing size divided by the number of sides it has.. And for B i havent thought of that yet..

Hope this helps a little bit

Answer:

scatterplot b

Step-by-step explanation:

all of the points are farther away from the line than the other scatterplots

Answer: Scatterplot B

Step-by-step explanation:

Scatterplot B has the weakest fit because it is far away (and more scattered) from the line on the graph than on graphs A and C. Also, it is important to understand that the closer the dots are to the line on the graph, the more credible the data is, since there is a closer correlation to line and points. Hope that helps!

Answer:

180

Step-by-step explanation:

8x15 is 120. The formula to find the area of a right triangle is base x height divided by two.
120/2 is 60
60x3 is 180.
180 plants

Area of Triangle: 180 square units

Area of Semicircle: 314.15926536

Total Area: 494.15926536

Step-by-step explanation:

Answer:

Area of Triangle: 180

Area of Semi-circle: 157

Total Area: 337

Step-by-step explanation:

Area of triangle: 1/2(l x w)

1/2[(20) x (18)] = 180

Area of a semi-circle: 1/2(pi)(radius)²

1/2(3.14)(10)²

1/2(3.14)(100)

1/2(314)

157

((DON'T FORGET THAT IT'S ASKING FOR RADIUS AND NOT THE DIAMETER))

Total: add both areas

180 + 157

337

Answer:

You are correct

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let the tenth digit is x and units digit is y.

We have the following equations:

Simplify the second equation:

Solve by substitution:

Find y:

The number is 27

Here the equations are if the digits be a and b

3(a+b)=10a+b

Equate both

And

The number is 27

Answer:

1/12

Step-by-step explanation:

Total number of marbles = 5+7+4 = 16 marbles

Probability of picking a red marble = 5/16

Because the red marble is not returned back after being picked up, the total number of marbles is now 15.

Now,

Probability of picking a yellow marble = 4/15

The probability of picking a red and yellow marble will be the product of these two probabilities which will = 5/16 x 4/15 = 1/12

Answer:

I'm not totally sure what its asking, but here's a radio- 1:5

Answer:

y = x(5)

Step-by-step explanation:

Examples that prove this to be true are:

1(5) = y

y = 5$

2(5) = y

y = 10$

The reason this is correct is that it follows the same pattern on the graph.

Answer:

Step-by-step explanation:

So basically you have to do the Pythagorean Theorem here.

Which is =  a^2 + b^2 = c^2

So you'll put 35 in 'a' and 84 in 'b'

It'll be like this = 35^2 + 84^2 = c^2

So here, we are looking for 'c'

And 'c' is the hypotenuse

So,

Step 1: 35^2 + 84^2 = c^2

Step 2: You will use the exponents (but not for c)

=  1225 + 7056 = c^2

Step 3: You will now add 1225 + 7056 = 8281

Step 4: Now, square root 8281√8281 = 91

91 = c

Hope this helps! Please let me know if you get this correct!

First off, let's give our definitions to what we are doing here, so late this becomes more understandable to you

Algebra - the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Division - the action of separating something into parts or the process of being separated

Answer:

1/2 & 1/10

Step-by-step explanation:

Each of three:

15 outcomes have all three digits 1 through 8

So, 15/30 which is 1/2

Fewer than 2 is one or none being effective, i.e one or no digits are 1 through 8

There are only three such outcomes

So, 3/30 = 1/10

Answer:

1.9

Step-by-step explanation:

1.85 is expressed to 2 decimal places.  Since the '5' is ≥ 5, we round 1.85 UP to 1.9.

Answer:

2 No

3 Yes 15 is divisible by 3, because 15 ÷ 3 = 5

4 No

5 Yes 15 is divisible by 5, because 15/5=3

9 No

10 No

Answer:

No, yes, no, yes, no, no, no

Step-by-step explanation:

If you're looking for a perfect answer, no decimals or anything then this would be the right answer. 15 has the factors or 5, 3, 1 and 15. Technically, 15 is divisable by all these numbers, but the quotient isn't perfect...

Answer:

C) 9 and 6/12

Step-by-step explanation:

The easiest way to do this would be to turn both of the mixed numbers into improper fractions, this makes 6 and two sixths into 6 x 6 +2= 38/6 and 1 and one half into 1 x 2 + 1 = 3/2. From there multiple the numerators together (38x3) and the denominators together (6x2) to get 114/12. To turn this into a mixed number again, divide 114 by 12 to get 9 with a remainder of 6 to get 9 and six twelfths

Answer:

According to the given attachment

L is a straight line and we know Sum of all angles formed on a straight line is 180° .

So,

➠ a + 90° + b = 180°

➠ a + b = 180° - 90°

➠ a + b = 90°

If angle a = angle b so we can easily find the value of a & b .

So, according to me " the given figure has not enough information to find out the value of a & b .
