The formula for the speed of a tsunami in deep water is v=gh−−√ , where g is acceleration due to gravity, 9.8 m/s2 , and h is the depth of the ocean in meters. Use this formula to estimate the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.

Answers

Answer:

v = 200 m/s

Step-by-step explanation:

The formula for the speed of a tsunami in deep water is given by :

[tex]v=\sqrt{gh}[/tex]

Here,

g is acceleration due to gravity

h is the depth of the ocean in meters.

We need to find the speed at which the tsunami that started with an earthquake in Sumatra struck Sri Lanka about 1550 km away. The Bay of Bengal is 4 km (4000 m) deep.

It means we need to find v if h = 4000 m

So,

[tex]v=\sqrt{10\times 4000}\\\\v=200\ m/s[/tex]

So, the speed of the tsunami is 200 m/s.

What is the volume of a rectangle prism 11inches long, 6 inches wide and 3 inches high

Answers

Answer:

198 inches^3

Step-by-step explanation:

Volume of a rectangular prism = Length × width × height

Length = 11 inches

Width = 6 inches

Height= 3 inches

Volume of a rectangular prism = Length × width × height

= 11 inches × 6 inches × 3 inches

= 198 inches^3

The volume of the rectangular prism with dimensions 11 inches long, 6 inches wide, 3 inches high is 198 cubic inches

Commutative property of multiplication

Step-by-step explanation:

This property states that numbers can be switched around when multiplying and the answer still remains the same

Answer:

C

Step-by-step explanation:

So we have the expression:

[tex]63\cdot 3[/tex]

And Jared rewrote it as:

[tex]3\cdot 63[/tex]

In other words, he just switched the order and the expression remains equivalent.

This is an example of the commutative property of multiplication, which states that if you change the order of a multiplication sentence, the sentence will remain equivalent.

So, our answer is C.

x ( > or = ) 5/9

Step-by-step explanation:

● 2(1 + x) ( > or = ) 11 - 3x

● 2 + 2x ( > or = ) 11 - 3x

Add 3x to both sides

● 2 + 2x + 3x ( > or = ) 11 - 3x + 3x

● 2 + 5x (> or = ) 11

Substract 2 from both sides

● 2 + 5x -2 ( > or = ) 11 -2

● 5x (> or =) 9

Divide both sides by 5

h(n)=4n+ 4 find h (-3)

Answers

Step-by-step explanation:

h(n)=4n+ 4 find h (-3)

h(-3)=4(-3)+4

=-12+4

=--8

Answer: -8

Step-by-step explanation: h(n) = 4n + 4 means that

if we put an n into our function, a 4n + 4 comes out.

So here, we're putting a -3 into our function which means that

a 4(-3) + 4 comes out which simplifies to -12 + 4 or -8.

So h(-3) = -8 or the value of the function at -3 equals -8.

Answers

Answer:

height= 4.8cm

Step-by-step explanation:

volume= length×width× height given the volume and length and width, 288=12×5×h

288=60h

divide both sides by 60

h=4.8cm

Answer:

h = 4,8 cm

m = 1152 g

Step-by-step explanation:

V = l×w×h

h = V/l×w

= 288cm³/12cm×5cm

= 288cm³/60cm²

= 4,8 cm

1cm³ .............. 4g

288cm³ ........ xg

x = 288cm³×4g/1cm³ = 1152 g

Answers

Answer:

After 4 minutes

Step-by-step explanation:

Balloon 1

Initial position = 10 mRise rate = 15 m/min

Balloon 2

Initial position = 150 mDrop rate = 20 m/min

Time required for the balloons to meet = x

After x minutes the first balloon will be at position:

10 + 15x

And the second balloon will be at position:

150 - 20x

Since they meet after x minutes, their position must be same:

10 + 15x = 150 - 20x15x + 20x = 150 - 1035x = 140x = 140/35x = 4 minutes

So the balloons will meet after 4 minutes

Maggie’s brother is 3 years younger than four times her age the sum of their ages is 27

18-4=14

14+6=20

Answer:

[tex]\huge\boxed{\text{Maggie = 6 years, Brother = 21 years}}[/tex]

Step-by-step explanation:

We can create two equations based on the word problems, where [tex]m[/tex] is Maggie's age and [tex]b[/tex] is her brother's age.

[tex]m + b = 27[/tex]

[tex]b = 4m - 3[/tex]

We can now substitute [tex]4m-3[/tex] in as [tex]b[/tex] into [tex]m+b=27[/tex].

[tex]m + (4m-3) = 27\\\\5m - 3 = 27\\\\5m = 30\\\\m = 6[/tex]

Now that we know the value of [tex]m[/tex], we can substitute it into [tex]m+b=27[/tex].

[tex]6 + b = 27\\\\b = 27-6\\\\b = 21[/tex]

-1 1/5 + -3/5 in simplest form

Answers

Answer:

-1 4/5

Step-by-step explanation:

In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole. For example, in the fraction 3  5, the numerator is 3, and the denominator is 5. A more illustrative example could involve a pie with 8 slices. 1 of those 8 slices would constitute the numerator of a fraction, while the total of 8 slices that comprises the whole pie would be the denominator. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5  8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below.
