Step-by-step explanation:

The area of the triangle with the given base and height where a = 4 and c = 2 is: 608 cm²

Area = 1/2(base)(height).

Given the parameters:

If a = 4 and c = 2, then:

Area = 1/2(base)(height) = 1/2(2ac²)(2ac² + 6)

Area = 1/2(2 × 4 × 2²)(2 × 4 × 2² + 6)

Area = 1/2(32)(38)

Area = 608 cm²

Since whole numbers do not include fractions and decimal values, 55 is the answer

By using the vertical line test, we conclude that graphs 4 and 5 don't represent functions.

The criteria to know when a graph represents or not a function, is to draw a vertical line and see if the line intersects the graph in more than one point. (This is called the vertical line test).

If you do that with graphs 4 and 5, you will see that these two do not represent functions.

For the other graphs is immediate to know that:

Answer: b

Step-by-step explanation:

The expression represents the surface area of the prism is 2.24+120+160+200. Therefore, option B is the correct answer.

Here a triangular prism has been provided with some measurements.

We have to find Which expression can be used to find the surface area of the following triangular prism.

The formula for the surface area of a triangular prism is formed by adding up the area of all the rectangular and triangular faces of a prism. Observe the following figure of a triangular prism to know the dimensions that are considered to frame the formula.

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 +S2 + S3)L + bh

Here, S1, S2 and S3 are sides of triangles, l=length of the prism, b=base and h=height.

Now, (6+8+10)20+8×6=120+160+200+48

=2.24+120+160+200

The expression represents the surface area of the prism is 2.24+120+160+200. Therefore, option B is the correct answer.

Answer:

3 = x

Step-by-step explanation:

Well, the two unknown sides share the same size due to the same angle, so now, using the fact we only have the info about one side, we need to do a reverse pythagorean theorem.

[tex]c^{2} = a^{2} + b^{2}[/tex]

Our a and b are the same, so I will change them to "x" and combine them.

[tex]c^{2} = 2(x)^{2}[/tex]

Now we plug in our "c" and square it ("C" in this case is: [tex]3\sqrt{2}[/tex] )

[tex]18 = 2(x)^{2}[/tex]

[tex]9 = x^{2}[/tex]

3 = x

Step-by-step explanation:

a=60°{vertically opposite angles}

b=180°-(52+110)°=18°

c=180°-(60+18)°=102°

d=180°-102°=78°

e=180°-(78+51)°=51°

A rational number is one that can be expressed as x/y. The first statement is false. All whole numbers are rational. They can always be expressed as x/1

Some rational numbers are not whole numbers. That's true. 4/7 is rational but not whole.

Some irrational numbers are not integers. I'm tempted to say this is true.

pi is irrational and it certainly is not an integer.

Answer:

150%

Step-by-step explanation:

half of 6 is three, and 9 has a value of 3 more than 6. meaning that 9/6 = 150%

Answer: [tex]150[/tex]% [tex]([/tex][tex]0.54[/tex][tex])[/tex]

Step-by-step explanation:

For fraction: divide 6 by 100 and remove the % sign.

{[tex]6[/tex]}% [tex]=\frac{6}{100}[/tex]

For decimal: move the decimal point 2 places to the left and remove the % sign.

{[tex]6[/tex]}% [tex]=0.06[/tex]

[tex]100[/tex]% [tex]=9[/tex]

[tex]\frac{6}{100}[/tex] × [tex]9=0.06[/tex] × [tex]9=0.54[/tex]

Step 2: Rotate the couch 90° counterclockwise.

Rule: (x, y) → (-y, x)

Step 3: Now reflect the "new" couch over the y-axis.

Rule: (x, y) → (-x, y)

Step 4: Finally translate the new new" couch right 1 unit and up 5 units.

Rule: (x + 1, y + 5)

There are many rules that apply to operations involving exponents. In this question, we'll need the following:

We're given:

[tex]z^{21}\div z^7=z^k[/tex] (solve for k.)

⇒ Rewrite as a fraction:

[tex]\dfrac{z^{21}}{z^7}=z^k[/tex]

⇒ Use the division rule:

[tex]z^{21-7}=z^k\\z^{14}=z^k\\14=k[/tex]

Therefore, the value of k is 14.

k = 14

Answer:

Green: (2/11) * (1/10)

Yellow: (2/5) * (1/3)

Purple: (3/10) * (6/19)

Blue: (1/4) * (13/51)

Step-by-step explanation:

 Green:

>> Maria has 11 letters in her bag, and 2 of them are B's.

>> At first, the chance of drawing a B is 2 out of 11: 2/11.

>> Let's assume that everything goes according to plan, and she actually draws a B.

>> Then she has 10 letters, and only one of them is B (she already has the other one).

>> That means that the chance of drawing that B is 1 out of 10: 1/10.

>> Thus, (2/11)*(1/10).

 Yellow:

>> There are 11 + 13 + 16 = 40 items in the closet.

>> The probability of selecting a prop is 16/40 = 2/5 (there are 16 props and 40 items).

>> That means that there are 40-1=39 items left.

>> Therefore, the probability of selecting a costume is 13/39 = 1/3 (as there are 13 costumes and 39 items).

>> The answer is (2/5) * (1/3).

 Purple:

>> There are 6+8+6=20 jellybeans.

>> At first, Hannah grabs an orange candy (there are 6 of them): 6/20 = 3/10.

>> Then there are 19 candies left.

>> Then she grabs a pink one (there are 6 of them): 6/19.

>> The answer is (3/10)*(6/19).

 Blue:

>> There are 52 cards in a standard deck, 13 clubs, 13 spades, 13 hearts, 13 diamonds.

>> The 1st is a spade: 13/52 = 1/4.

>> There are 51 cards left.

>> The 2nd is a club: 13/51.

>> (1/4)*(13/51).
