For scientific notation, you always want 1 digits in front of the decimal.

Ex) 7.39*10^5

Move the decimal point in between the 1 and 4, or 1 place to the left.

1.435

Since the decimal point was moved 1 place to the left, the exponent after 10 will be 1.

1.435*10^1

1.435*10^1 is your final answer.

1.435*10 is the same thing also.

You're given a table of x values and an equation. To solve, plug in the values for x.

First box: y=2(-3)-1=-7
Second box: y=2(-2)-1=-5.

See if you can solve the third one.

Need to find volume, step by step explanation pls

worty [1.4K]

Given:

A figure of combination of hemisphere, cylinder and cone.

Radius of hemisphere, cylinder and cone = 6 units.

Height of cylinder = 12 units

Slant height of cone = 10 units.

To find:

The volume of the given figure.

Solution:

Volume of hemisphere is:

$V_1=\dfrac{2}{3}\pi r^3$

Where, r is the radius of the hemisphere.

$V_1=\dfrac{2}{3}(3.14)(6)^3$

$V_1=\dfrac{6.28}{3}(216)$

$V_1=452.16$

Volume of cylinder is:

$V_2=\pi r^2h$

Where, r is the radius of the cylinder and h is the height of the cylinder.

$V_2=(3.14)(6)^2(12)$

$V_2=(3.14)(36)(12)$

$V_2=1356.48$

We know that,

$l^2=r^2+h^2$ [Pythagoras theorem]

Where, l is length, r is the radius and h is the height of the cone.

$(10)^2=(6)^2+h^2$

$100-36=h^2$

$\sqrt{64}=h$

$8=h$

Volume of cone is:

$V_3=\dfrac{1}{3}\pi r^2h$

Where, r is the radius of the cone and h is the height of the cone.

$V_3=\dfrac{1}{3}(3.14)(6)^2(8)$

$V_3=\dfrac{25.12}{3}(36)$

$V_3=301.44$

Now, the volume of the combined figure is:

$V=V_1+V_2+V_3$

$V=452.16+1356.48+301.44$

$V=2110.08$

Therefore, the volume of the given figure is 2110.08 cubic units.

Marlon asks a friend to think of a number from 5-11. What is the probability that marlins friend will think of the number 9

Tju [1.3M]

Answer:

14.29% probability that Marlon's friend will think of the number 9

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this problem, we have that:

There are 7 numbers from 5 to 11(5,6,7,8,9,10,11)

9 is one of them

$p = \frac{1}{7} = 0.1429$

14.29% probability that Marlon's friend will think of the number 9

Anna has $430. She wants to buy a phone that costs $275. Anna will also have to pay a sales tax of 7%.

ki77a [65]

19.25 (tax)
294.25 (total price)
135.75 (money left)

REASONING:

In this word problem it says Anna has 430 dollars. The phone costs 275 dollars. It also says that when she buys the phone, she will have to pay a tax of 7%.

To find how much tax she will pay, we must do [275] x [0.07]

After inputting this into a calculator, you will get 19.25 (tax)

To find the total price, all you have to do is add 19.25 to 275. When you do this, you will get 294.25 dollars (total price)

To find how much money she has left,

430-294.25=135.75 (money left)
