The area if base x height

8 x height = 96

Divide both sides by 8 to find the base size:

Answer:

writing. a good pen of the type and point size that's most comfortable for you. Generally I find that fine-point pens are the best for taking notes. You can write smaller and get more on a page. If your handwriting tends to be small, you'll probably prefer a fine point.

Answer:

263

Step-by-step explanation:

Let the number = xyz

The 6 has a digit on its left and on its right. It must be the middle number.

y = 6, so the number is x6z.

The 2 is not the last digit. It must be the first digit.

x = 2, so the number is 26z.

The remaining digit — 3 — must be the last digit.

z = 3, and the number is 263.

The mystery number is 263.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Let the three digit number be xyz.

The digits are 3,6,2.

The mystery number can be found as

Hence we can conclude that the mystery number is 263.

Answer:

independent is the time. time does change throughout the experiment.

Dependent is texting speed as it can vary.

hope this helps :)

Answer:

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. Which would make him see the fish in a spot that its not at. So 2 is the correct answer.

Answer:

a = 9m

Step-by-step explanation:

You can take the volume of the water tank as the volume of a cube.

The volume of a cube with side a is given by:

V=a*a*a = a^3

To find the value of a you do a the subject of the formula:

a=(V)^{1/3}

You replace and obtain for a:

a = (729m^3)^{1/3} = 9m

hence, the rim a of the water tank is 9m

Answer: The side of the tank is 9 m.

Step-by-step explanation: A water tank is normally a cube, which means length, width and height has the same measure.

To calculate Volume of a cube:

V = length*width*height

Knowing that volume is 729 and assuming sides are x:

x*x*x = 729

x³ = 729

x = [tex]\sqrt[3]{729}[/tex]

x = 9

The volume is in cubic meters, so sides of the tank measures 9 m.

Answer: $22.12

Step-by-step explanation:

I just did the compound interest formula which is

starting amount * (1. interst rate) ^ number of years

example if you have 100$ and you want to know how much it is worth if it appretiates by 7% of a period of 20 years it would look something like this;

100 * (1.10) ^20 = 672.74$

but since you have to figure out what it was in 2008 which was exactly half way in the period you divide the exponent by half so your formula should be;

I know the answer is right because I asked my teacher and it's correct.

REAL EXAMPLE: 18 * (1.51) ^.5 = 22.12$

The amount should be $22.12.

[tex]= 18 \times (1.51) ^{.5}[/tex]

= $22.12

Answer:

2x - 5

Step-by-step explanation:

2x^3 + 4x = 2x(x^2 + 2)

-5x^2 - 10  = -5(x^2 + 2)

so the factors are  (2x - 5)(x^2 + 2).

Answer:

I would use box-and-whisker plots to compare the two sets of prices. The plots will show the ranges, which is the difference least and greatest data points. Also, the medians will divide each set of data into 4 equal groups. Comparing these middle values and range of prices in each group will show how similar the prices are.

divide 10.5by 35/100

Answer:

2/3

Step-by-step explanation:

2nd term = 2/5

5th term = 16/135

Nth term for any series is given by [tex]a r^n-1[/tex]

where a is the forst term

r is the common ratio

for 2nd term

[tex]2nd \ term = ar^n-1 = 2/5\\2nd \ term = ar^2-1 = 2/5\\2nd \ term = ar= 2/5\\[/tex]

for 5th term

[tex]5th \ term = ar^5-1 = 16/135\\\\5th \ term = ar^4 = 16/135\\[/tex]

Since we have to eliminate a  and find r .

we can divide 5th term by second term

then we get the following equation

[tex]2nd term/ 5th \ term = ar/ar^4 = (2/5) / (16/135)\\=>1/r^3 = 2*135/5*16 \\=>1/r^3 = 27/8\\=>1/r = \sqrt[3]{27/8} \\=> 1/r = 3/2\\=> r = 2/3[/tex]

\

Thus, common ratio is 2/3.

Answer:

+3

Step-by-step explanation:

Where the graph crosses the x axis is where the real zeros exist. The parabola's minimum is at point (-3,-3) by adding a +3 to the right side of the equation will raise the minimum to point (-3,0) therefore giving it only one point where it touches the x axis. Then the parabola will only have one zero, the minimum of the parabola.

Answer:

519

Step-by-step explanation:

Let's assume that the scores for the national verbal proficiency test follow a normal distribution.

Mean score (μ) = 500

Standard deviation (σ) = 75

According to a Z-score table, the score for the 60th percentile is roughly z = 0.253

For any score "x", the z-score is given by:

[tex]Z=\frac{X-\mu}{\sigma}[/tex]

For z = 2.53:

[tex]0.253=\frac{X-500}{75}\\X=519[/tex]

The raw score to the 60th percentile is 519.
