What is the value of x in the figure?
60°
(2x)

Answer:

The ratio of boys to girls is 4:5. So let 4x be the number of boys and 5x be the number of girls. Then 4x+5x = 9x is the total number of students. Then the fraction of boys in the class is 4x/9x = 4/9.

Answer:

12 ft²

Step-by-step explanation:

the rectangular hole area:

l • w = A

3 • 2 = 6 ft

the triangular hole area:

(b • h) / 2 = A

(4 • 3) / 2 = 6 ft

6 ft + 6 ft = 12 ft²

Answer:

7.5

Step-by-step explanation:

The probability of winning = 3 out of 20 ;

P(winning) = 3/20

Predicted Number of winnings if game is played 50 times ;

P(winning) * number of games played

(3 /20) * 50

0.15 * 50

= 7.5

Predicted Number of winnings = 7.5

Answer:7.5

Step-by-step explanation:

first you want to clarify the numbers which is 3 and 20 and your chance is 3/20 which equals 7.5 but round to the nearest whole number so 8,

Answer:

73,205

Step-by-step explanation:

The answer is

Subtract 2 from 5 to get 3.

3x2=6

subtract 7 from -4 to get -11

Add -2 and 4 to get 2.

Fraction  

can be rewritten as −  

by extracting the negative sign.

Convert 6 to fraction 12/2

Since the 2 fractions have the same denominator, subtract them by subtracting their numerators.

1/2= 0.5 (decimal form)

Answer:

  False

Step-by-step explanation:

Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.

  sin(B) > sin(Y) . . . . FALSE

  sin(B) = sin(Y) . . . . true

Answer:

x = 5

Step-by-step explanation:

x² + (2x+2)² = (2x+3)²

x² + 4x² + 8x + 4 = 4x² + 12x + 9

x² - 4x - 5 = 0

(x - 5)(x + 1) = 0

x = -1  This can be discounted as the answer because you cannot have a negative length

answer: x = 5

Answer: Well if you buy a pack of socks with 15 for $9 you are not getting the best deal over buying a pack of socks with 20 for $11. The reason behind this is because each sock is worth $0.6 meaning that you are only paying two extra dollars for five socks which would have normally cost $3. Shawn (with the 20 pack) is saving $1.

Im so sorry i don't know.

Answer:

125 units^3

Step-by-step explanation:

Volume is l*w*h = V. A cube has all equal sides so wecan divide 1000 by 3 and get our side lengths.

You then divide the sides by 2 because the question says the second cubes sides are half the size

5*5*5 = 125

The volume of the second cube is 125 units³.

In mathematics, ‘Volume’ is a mathematical quantity that shows the amount of three-dimensional space occupied by an object or a closed surface.

Given that a cube has volume 1000 units³ and another smaller cube has smaller volume has side only half as long.

We need to find the volume of the second cube,

So, let the side of the first cube be x,

We know that the volume of a cube = side³

Therefore,

x³ = 1000

x = ∛1000

x = 10 units

Therefore, the second cube will have a side of 10/2 = 5 units

Volume of second cube = 5³ = 125 units³.

Hence the volume of the second cube is 125 units³.

V=1/3 (8.3)(6.3)

V=17.43

V=17.4m^3

Answer:

h = 22.91 cm

Step-by-step explanation:

Given that,

The volume of a vase, A = 1330.2 cm³

Radius of the vase, r = 4.3 cm

We need to find the height of the vase. The formula for the volume of a cylinder is given by :

[tex]V=\pi r^2 h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{1330.2 }{3.14\times (4.3)^2}\\\\h=22.91\ cm[/tex]

or

h = 23 cm

So, the height of the vase is equal to 23 cm.
