Answer:

81/16 = 5 1/16

Step-by-step explanation:

-4(square root of x) -3 = -12

Add 3 to both sides

-4(square root of x) = -12 +3 = -9

Divide both sides by -4

(square root of x) = -9/-4

-/- equals +

(square root of x) = 9/4

Square both sides to cancel the square root

x = (9/4)^2 = 81/16 = 5 1/16

Answer:

16.7%.

Step-by-step explanation:

There are initially 24 + 15 + 8 = 47 pencils in the bag.

Take a pencil out of this bag of 47 pencils. 15 out of the 47 pencils blue. Let A represent the event of getting a blue pencil on the first pick. The probability of getting a blue pencil is:

\displaystyle P(A) = \frac{15}{47}.

There are now 47 - 1 = 46 pencils left in the bag. However, given that the first pencil removed from the bag is blue, the number of red pencils in the bag will still be 24. Take another pencil out of this bag of 46 pencils. Let B represent the event of getting a red pencil on the second pick. The possibility that the second pencil is red given that the first pencil is blue will be:

\displaystyle P(B|A) = \frac{24}{46}.

The question is asking for the possibility that the first pencil is blue and the second pencil is red. That is:

\displaystyle P(A\cap B) = P(A) \cdot P(B|A) = \frac{15}{47}\times \frac{24}{46} = 0.166512 \approx 16.7\%.

Solve for X. Please!!
pychu [463]

Answer:

x = 37.5

Step-by-step explanation:

By Basic Proportionality Theorem:

\frac{x}{20}  =  \frac{46 - 16}{16} \\  \\   \frac{x}{20}  =  \frac{30}{16} \\  \\  x =  \frac{20 \times 30}{16}  \\  \\ x =  \frac{600}{16}  \\  \\ x = 37.5

It takes a jet 2 hours to fly 1100 miles at this rate. How far does it fly in 8 hours
aivan3 [116]

Answer: The jet will fly 4400miles in 8 hours.

Step-by-step explanation:

Let the missing value be represented by x

2 hours = 1100 miles

8 hours = x

We cross multiply:

2x = 1100 x 8

2x = 8800

Divide both sides by 2 to get the value of x

x = 8800/2

x = 4400

Therefore, the jet will fly 4400miles in 8 hours.

Pls help me on this math watch!!! this is non calculator

The height of the cone is 4 cm (approx).

Step-by-step explanation:

Given,

The radius (r) of the cone = 4.96 cm

Volume (V) = 102 cm³

To find the height (h) of the cone.

Formula

The volume of a cone V = \frac{1}{3}πr²h

Now,

According to the problem,

\frac{1}{3}πr²h = 102

or,  \frac{1}{3}×\frac{22}{7}×(4.96)²h= 102

or, h = \frac{102X7X3}{4.96^{2}X22 }

or, h = 3.95 = 4 (approx)

so,

Height = 4 cm (approx)
