What Is The Distance Of Segment BF Round To The Nearest Hundredth.

Answers

Answer 1

Answer:

BF ≈ 7.07 cm

Step-by-step explanation:

ΔBCE:

Use the Pythagorean theorem:

[tex]EB^2=EC^2+BC^2[/tex]

We have EC = 4cm and BC = 3cm. Substitute:

[tex]EB^2=4^2+3^2\\\\EB^2=16+9\\\\EB^2=25\to EB=\sqrt5\\\\EB=5\ cm[/tex]

BF is the diagonal of the square FEBA. The formula of a diagonal of a square with side a is:

[tex]d=a\sqrt2[/tex]

Therefore

[tex]BF=5\sqrt2\ cm[/tex]

Approximation:

[tex]BF\approx5(1.414)=7.07\ cm[/tex]

a cone has a volume of 6 cubic inches. what is the volume of a cylinder that the cone fits exactly inside of

Answers

Answer:

= 18 cubic inches

Step-by-step explanation:

The volume of a cone is given by the formula;

V = 1/3 × base area × height

While that of cylinder is given by the formula;

Volume = Base area × height

Since we need the cylinder to fit exactly inside the cone, then it  means that their bases are the same and heights are the same.

Therefore;

The cone has three times less volume compared to the cylinder.

Thus;

Volume of the cylinder = Volume of cone × 3

                                       = 6 In³ × 3

                                       = 18 cubic inches

two cars are traveling in the same direction. The first car is going 40 mi/h, and the second car is going 55 mi/h. the first car left 3 hours before the second car. which equation could you solve to find how many hours it will take for the second car to catch up to the first car?

Answers

Answer:

8 hours

Step-by-step explanation:

first car: speed=40, time=(t+3), distance=s1

second car: speed=55, time=t, distance=s2

speed=distance/time

distance=speed×time

s1=40×(t+3)

s2=55×t

since the cars would travel the same distance; s1=s2

40(t+3)  = 55t

40t+120 = 55t

15t = 120

t=8

12 An expression is shown. 83.31 x 6.2 What is the value of the expression?

A. 505.422
B. 506.522
C. 513.422
D. 515.522

please explain thank you. ​

Answers

Answer:

Step-by-step explanation:

In this type of problem it's reasonable to use a calculator for the computation.  Here, 83.31·6.2 = 516.522.  Double check to ensure that you've copied all of the possible answer choices correctly.

The value of the expression is 516.522, which corresponds to option B.

To solve the expression 83.31 * 6.2, we need to multiply the two numbers. Here is the step-by-step calculation:

Multiply 83.31 by 6.2 without considering the decimal places: 8331 * 62 = 516,522.

Count the total number of decimal places in the factors. In this case, 83.31 has two decimal places, and 6.2 has one, so there are three decimal places in total.

Place the decimal point in the result (516,522) to reflect the combined number of decimal places from the factors: 516.522.

Therefore, the value of the expression 83.31 x 6.2 is 516.522, which corresponds to option B.

Which number is greater than (>) 6.841?

Answers

Answer:6.95

6.95= 6.95>6.841

6.8= 6.800<6.841

6.786<6.841

6.839<6.841

Answer:

6.95

Step-by-step explanation:

We can find the answer by analyzing the options and deducing which is greater or less.

That is, if we have the number 6.841, the number 6.95 must be greater because it has 9 intead of an 8, which makes it a bigger number.

We can also make a division between the original number and the number that we want to know if it is greater or less, and if the division is less than 1 it means that the number is greater, and if the division is greater than 1 it means that the number is smaller.

6.841/6.8 = 1.006 ⇒⇒ 6.8 is smaller than 6.841

6.841/6.786 = 1.008 ⇒⇒ 6.786 is smaller than 6.841

6.841/6.839 = 1.0003 ⇒⇒ 6.839 is smaller than 6.841

6.841/6.95= 0.98 ⇒⇒ 6.95 is greater than 6.841

x/-9 ​≥ 3

Solve for x

Your answer must be simplified

(x/-9 is supposed to be a fraction)

Answers

Answer:

x ≤ -27

Step-by-step explanation:

x/-9 ​≥ 3

well since theres division and we want to separate the x's and the naked numbers by themselves were going to have to multiply

x ≥ 3 x -9

x ≥ - 27  (but since theres a negative the symbol  ≥ is going to switch)

x ≤ -27

TIP: remember we always do the opposite when switching a numbers place for example if we have +9 if we switch it place to the other side its going to become -9, same thing with multiplication and division.

example:

3 + x = 5                          or           3x = 5

x = 5 - 3                                          x = 5/3

~batmans wife dun dun dun...aka ~serenitybella

The solution to the inequality (x/-9) ≥ 3 in fraction form is x ≤ -27.

The relationship between the two values which are either greater or lesser than each other but not equal is called inequality.

The primary application of inequality is to compare two numbers on a number line.

The inequality can be solved as:

(x/-9) ≥ 3

 Multiply both sides of the inequality by -9. The multiplication of a number with a negative sign changes the direction of the inequality.

The equation can be written as:

[tex]\dfrac{-9x}{-9} \leq -9(3)[/tex]

x ≤ -27

Thus, the solution to the inequality (x/-9) ≥ 3  is x ≤ -27.

On the Richter scale, the magnitude, M, of an earthquake is given by M= 2/3logE/Eo, where E is the energy released by the earthquake measured in joules, and Eo is the energy released by a very small reference earthquake. Eo has been standardized to 10^4.4 joules.

Part A
The earthquake in Haiti in 2010 released 2.0*10^15 joules. What was its magnitude on the Richter scale?

Part B
If the energy release of one earthquake is 10,000 times that of another, how much larger is the Richter scale reading of the larger earthquake than the smaller?

Answers

Answer:

See below

Step-by-step explanation:

Part A

Formula

M = 2/3 * log(E/Eo)

Givens

M = ??

E = 2 * 10^15 joules

Eo = 10^4.4

Solution

M = (2/3) * log(2 * 10^15 / 10^4.4)

M = (2/3 ) log (7.96 * 10 ^ 11)

M = (2/3) * 11.901

M = 7.934

Part B

What the question is saying is that E/Eo = 10000

You don't have to figure out exact values.

M = 2/3 * log(10000)

M = 2/3 * 4

M = 8/3 or 2 2/3 or 2.66667

If you have choices, please list them.

Answer:

A ; M = 7.267

B ; M = 2.667

Step-by-step explanation:

Formula

M = (2/3) log (E/Eo)

M = 2/3 * log (2 * 10^15/10^(4.4) )

M = 2/3 * log( 7.9621* 10^10)

M = 2/3 * 10.901

M = 7.267 on the Richter scale.

Part B

Suppose that you use Eo and your base. Eo is 10^4.4

Now the new earthquake is E = 10000 * Eo

So what you get now is M = (2/3)* Log(10000 * Eo / Eo )

M = 2/3 * log(10000)

M = 2/3 of 4

M = 8/3

M = 2.6667

What this tells you is that if the original reading was (say) 6 then the 10000 times bigger reading would 8.266667

A shipment to a warehouse consist of 4500 MP3 players. The manager chooses a random sample of 50 MP3 players and finds 2 are defective. How many MP3 players in the shipment are likely to be defective?

Answers

number of MP3 players: 4500

based on information given, 2 out of 50 MP3 players are defective. this means every 50 samples, 2 would be defective

4500/50 = 90

90 • 2 = 180

so, your final answer would be:

180 MP3 players in the shipment are likely to be defective

There are likely approximately 180 defective MP3 players in a shipment of 4,500 units.

The question asks how many MP3 players in a shipment of 4,500 units are likely to be defective given that a random sample of 50 MP3 players found 2 defective ones. To estimate the number of defective players in the entire shipment, we can use proportion. If 2 out of 50 MP3 players are defective, we set up a proportion to estimate the likely number of defectives in the entire 4,500 units.

Assuming the sample is representative of the whole shipment, the proportion would be:

2 (defective in sample) / 50 (sample size) = x (estimated defectives in shipment) / 4,500 (shipment size)

To solve for x, the likely number of defective MP3 players, we cross-multiply and divide:

2 / 50 = x / 4,500
50x = 2 * 4,500
50x = 9,000
x = 9,000 / 50
x = 180

Therefore, using the sample proportion, we would expect there to be approximately 180 defective MP3 players in the shipment.

Carla spent two-fifths of her savings on a bracelet and had 9 left over. How many dollars did Carla's bracelet cost?

Answers

Final answer:

Carla spent two-fifths of her savings on a bracelet and had $9 left. Her original savings were $22.50, so the bracelet cost $9.

Explanation:

Carla spent two-fifths of her savings on a bracelet and had $9 left over. To determine the cost of Carla's bracelet, we need to let s represent her original savings. According to the problem, the remaining savings after purchasing the bracelet is s - (2/5)s = $9.

To solve for the cost of the bracelet, we can set up the equation (2/5)s = s - $9. By multiplying both sides by 5/2 to isolate s, we get:

s = (5/2) * ($9)

s = $22.50

So her original savings were $22.50. This means Carla spent (2/5) * $22.50 on the bracelet. Calculating this gives:

Cost of bracelet = (2/5) * $22.50

Cost of bracelet = $9

Thus, Carla's bracelet cost $9.

Answers

Answer:

ok

Step-by-step explanation:

The value of x, given the equation, can be found to be (5y - 35) / 6.

How to solve for x ?

To find the value of x in the equation 6x = 5y - 35, you need to isolate x.

Start with the equation:

6 x = 5 y - 35

To isolate x, divide both sides of the equation by 6:

( 6 x ) / 6 = ( 5 y - 35 ) / 6

Simplify both sides:

x = ( 5 y - 35 ) / 6

So, the value of x is ( 5 y - 35 ) / 6.

The sum of the two numbers is -18.

Step-by-step explanation:

You can work your way through the problem starting with ...

1/3 the difference of two numbers is 12

Since 3 times 12 is 36, the difference of the two numbers is 36.

Then you are told ...

the larger number is 9

so the smaller number will be 9 less the difference, or ...

smaller number = 9 - 36 = -27.

Now, you know both numbers, so you know there sum is ..

9 + (-27) = -18 . . . . . sum of the two numbers
