b = base

h = height

A = hb / 2

A = (3*6) / 2

A = 18 / 2

A = 9 units2

Answer:

Put both equations into standard form (Ax+By=C).

Multiply one or both of the equations by a number so that you will have opposite coefficients on the same variable.

Add the two equations together. Add the x's, the y's, and the numbers.

Solve for the variable.

Take your answer from the last step and plug it into of the equations (pick the one that looks easiest).

Your solution will be in the form of a coordinate point (x,y).

Answer: 1/16 or 0.0625

Step-by-step explanation:

The probability of getting a heads is 1/2, and the probability of getting a tails is 1/2. To find the probability of getting 2 heads and 2 tails, multiply the probabilities of each event together. 1/2 * 1/2 * 1/2 * 1/2 = 1/16.

Answer: 156

Step-by-step explanation: do 600 x 0.26 since 0.26 = 26%, 0.26 x 600 is 156.

Answer:

156

Step-by-step explanation:

600/x=100%/26%

[tex]\frac{x}{600}[/tex] [tex]\frac{26}{100}[/tex]

x=156

Answer:

59°

Step-by-step explanation:

The total of all the angles in a triangle should amount to 180°. So:

64° + 57° = 121°

180° - 121° = 59°

I took the k12 test. If I'm right please mark brainliest!

Answer:

I pretty sure it's 8cm.

Step-by-step explanation:

I multiplied 73,000 by 0.000074, which resulted in 5.402.
Then, I multiplied 73,000 by 0.000032, which resulted in 2.336.
I added the products together, which gave a sum of 7.738.
Then I rounded to the nearest whole number, which is 8, because the tenth in the decimal (.7) rounds up because it is >4.

Answer:

24 Units Cubed

Step-by-step explanation:

Start with the face of your 3D shape, which has a length/width of 3 units and a height of 4 units. Then look at the visible side of your figure, in this case it is the right side. You can see it's width/length of 2 units, so multiply 4x3x2, and in this case 4x3=12 and 12x2 is 24. making your answer 24 units cubed.

Answer:

24

Step-by-step explanation:

A=L×B×H

24UNITS^2

Mixed Number:

[tex]5\frac{1}{2}[/tex] or 5 1/2

Improper fraction:

2x5+1=11

[tex]\frac{11}{2}[/tex] or 11/2

Decimal:

5.5

5.5 because 5 is whole number, and then, 5 tenths because 5 is half of 10.

Percent:

1 whole = 100%

100% x 5 = 500%

500% + 50% (1/2) = 550%

550%

1st seat 6 possible for each 6 only 1 possible(spouse) for seat 2

3rd seat 4 possible for each 4 only 1 possible(spouse) for seat 4

5th seat 2 possible for each 2 only 1 possible(spouse) for seat 6

6 x 4 x 2 = 48

OR 3 couples possible arrangements 3 x 2 x1 = 6

each couple 2 possible 2 x 2 x 2 = 8

therefore 6 x 8 = 48

first one:

The surface area of a pyramid can be found using the formula:

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

Since the side lengths of the base are equal, the perimeter of the base is:

Perimeter of Base = 4 x Side Length

Perimeter of Base = 4 x 9 = 36 feet

To find the slant height, we can use the Pythagorean theorem:

Slant Height^2 = Height^2 + (1/2 x Side Length)^2

Slant Height^2 = 12^2 + (1/2 x 9)^2

Slant Height^2 = 144 + 20.25

Slant Height^2 = 164.25

Slant Height = 12.81 feet

The base area can be found using the formula for the area of a square:

Base Area = Side Length^2

Base Area = 9^2 = 81 square feet

Plugging in the values into the formula for surface area:

Surface Area = (1/2) x 36 x 12.81 + 81

Surface Area = 218.16 square feet

So the surface area of the pyramid is 218.16 square feet.

second one:

The surface area of a pyramid can be found using the formula:

Surface Area = (1/2) x Perimeter of Base x Slant Height + Base Area

Since the side lengths of the base are equal, the perimeter of the base is:

Perimeter of Base = 4 x Side Length

Perimeter of Base = 4 x 8 = 32 meters

To find the slant height, we can use the Pythagorean theorem:

Slant Height^2 = Height^2 + (1/2 x (Side Length1 + Side Length2))^2

Slant Height^2 = 3.5^2 + (1/2 x (8 + 4))^2

Slant Height^2 = 12.25 + 36

Slant Height^2 = 48.25

Slant Height = 6.94 meters

The base area can be found using the formula for the area of a square:

Base Area = Side Length^2

Base Area = 8^2 = 64 square meters

Plugging in the values into the formula for surface area:

Surface Area = (1/2) x 32 x 6.94 + 64

Surface Area = 107.52 square meters

So the surface area of the pyramid is 107.52 square meters.

Answer:

b i think

Step-by-step explanation:

because if you make it into a prism, the dimensions are basically the same

Divide the arrow into upper triangle and lower rectangle

area of triangle :-

[tex] \frac{1}{2} \times base \times height[/tex]

[tex] \frac{1}{2} \times 20 \times (15 + 8 + 8) \\ \frac{1}{2} \times 20 \times 31 = 310[/tex]

area of rectangle :-

[tex]length \: \times \: width \\ 15 \times 20 = 300[/tex]

add both the area :-

area of triangle+ area of rectangle = area of arrow

310 + 300 = 610 cm²

Answer:

x = 10

Step-by-step explanation:

Both obects are similar right. That means that they must have similar angles, similar sizes and similar scale factors.

For me by just looking at the figires I can conclude a similar scale factor which is 1.7. However we are going to calculate the scale factor.

First we must take notice that the triangle D'E'F' is an enlargement. So to find the scale factor we must the same sides of both triangle and divide the larger sid by the smaller side.

68 ÷ 40 = 1.7

Now that we have the scale factor (1.7) we can now find x.

The similer side D'F' = 17 and DF = x.

We are gonna use the scale factor to divide D'F' to find DF.

17 ÷ 1.7 = 10

Therefore x is 10

Finding ∠BOC :

Answer:

Alrighty... i am happy that you would like an explanation.. that is truly admirable...

let's begin!!!

Step-by-step explanation:

We need to place everything into an equation to solve for x... after that we can substitute the value for x into the expression for m<BOC to get its value (i hope this isn't confusing... the math is easier though... trust me)

8X -67 +9X -75 = 96              Add 67 and 75 to both sides to isolate x

8X +9X = 238       --> 17X = 238

divide both sides by 17 to get x = 14

then subsitute x = 14 into the expression for m < BOC

you get  8(14)-67 = 45

therefore, the measure of <BOC is 45 degrees

I really hope this helps!!!!!

Answer:

one expression equals 5 when so substituting 2for x and the other equals 9 because the expression are not equal.

Answer:

[tex]t = 10[/tex]

Step-by-step explanation:

Step 1:  Cross Multiply

[tex]\frac{5}{3} = \frac{t}{6}[/tex]

[tex](5 * 6) = (3 * t)[/tex]

[tex]30 = 3t[/tex]

Step 2:  Divide both sides by 3

[tex]\frac{30}{3} = \frac{3t}{3}[/tex]

[tex]10 = t[/tex]

Answer: [tex]t = 10[/tex]
