Three times a number is six more than twice the number.

Clare travels at a constant speed, as shown on the double number line.

Zanzabum

Answer:

How far does Clare travel in one hour?

A: 36

How far does Clare travel in three hours?

A: 108

How far does Clare travel in 3.5 hours?

A: 126

Step-by-step explanation:

Find the Unit Value

72/2 = 36

Clare travels 36 miles per hour

Therefore, you must multiply the hours by the Unit travel time for the answers.

1 X 36 = 36

3 X 36 = 108

3.5 X 36 = 126

The circumference of great circle of a hemisphere is 44 cm. find the total surface area of the hemisphere

max2010maxim [7]

Answer:

I didn't know if you meant that the circumference of tje hemisphere was 44 or if the circumference of the cirkel in which the hemisphere exists is 44 but you rearrange the numbers.

Step-by-step explanation:

The formula for calculating a circumference is 2×pi×r, with r as tje radius of the cirkel. So in this instance we get 2×pi×r=44. r=44/(2×pi)=7.00 centimeters. The total surface area of a cirkel=pi×r^2=pi×7.00^2=154.06 meters squared. 154.06/2=77.03 meters squared (hemisphere is half of a cirkel)

if $5,000,000 isinvested at 4% interest compunded continuously, how much willl the investment be worth in 30 years

Katarina [22]

The answer is $16216987.55 (IMPORTANT: This is the answer assuming that the interest rate is annually. The quesiton says 'continuously' so I was a bit confused)

To solve this problem, you can use the compound interest formula.

Here it is once you plug in the numbers: A = 5,000,000 ( 1 + .04) ^30

Just solve the equation to find the solution.

Solve for x -6 >_ 10 - 4x

Otrada [13]

We are given this inequality,

$-6\geq10-4x$

We will follow these steps to solve it:

Step 1:

First let us bring 10 to the left side.

10 is in addition on right, so we apply opposite operation of addition that is subtracting 10 from left side, we get

$-6-10\geq-4x$

$-16\geq-4x$

Step 2:

Next we have to eliminate -4 which is in multiplication with x on the right side.

So applying opposite operation of multiplication that is dividing both sides by -4.

We have to consider here that when we divide or multiply with a negative the sign of inequality reverses, that is ≥ becomes ≤ and vice versa.

$\frac{-16}{-4}\leq x$

x≥4

Answer is last option x≥4.

Answer all question for brainliest

Neporo4naja [7]

Answer:

4.

this shows that the height of 13 year old females in one class is less variable than the other class.
this means that the height of students in class with range 6 may vary from person to person while that in class with range 3 maybe clustered around one another.
we're expected to see students of almost same height in class ,with range 3, more than the students in class with range 6.

5.

arranging the values in ascending order

2, 2, 4, 4, 4, 5, 6, 6, 6, 8, 8, 9

$mean = \frac{ sum \: of \: all \: observations}{total \: number \: of \: observations}$
