Create a number line that represents the solution set of the inequality w divided by 7 > 38. Show all your work

Answers

Answer:

Step-by-step explanation:

To represent the solution set of the inequality w divided by 7 > 38 on a number line, we first need to isolate the variable w:

w/7 > 38

w > 7 x 38

w > 266

This means that any value of w greater than 266 satisfies the inequality.

We can represent this on a number line by marking a closed circle at 266 (since the inequality is not inclusive of this value), and drawing an arrow to the right to indicate all values greater than 266:

<--o======(266)---------------->

This represents the solution set of w/7 > 38.

Nadia is a stockbroker. She earns 12% commission each week. Last week, she sold $6,400 worth of stocks. How much did she make last week in commission? If she averages that same amount each week, how much did she make in commission in 2011?

Answers

Answer:

Nadia made a commission of 768 last week

The amount she made in 2011 is 40,045.824

Step-by-step explanation:

What is a commission?  

A commission is the fee got for the services, given by the percentage of the total worth.

If Nadia gets a 12% commission for $6400,

Commission = percentage ×  worth of stock

                    = 12% × 6400

                    = 768

There are 52.143 weeks per year.

The amount of commissions she made in 2011 is,

768 × 52.143 = 40,045.824

Hence, Nadia made a commission of $852 for $6400 worth of stocks. If she averages the same amount each week, Nadia made a commission of $40,045.824

nadia had made 768 in the last week. she made 40,046.24 in 2011

The Pyramid Arena In Memphis, Tennessee, is a square pyramid that is 321 feet tall. The base has 600-foot sides. Find the volume of the pyramid.

Answers

ANSWER: 38,520,000 cubic inches or 3.85 x 10^7


work:

The volume (V) of a pyramid is one third the area of the base (B) times the height of the pyramid (h).
V= 1/3​Bh
Since the pyramid is a square pyramid, so B=600×600=360000 sq feet

V= 1/3×360000×321= 38,520,000 cubic inches or V=3.85×10^7

Answer:

38,400,000 cubic feet.

Step-by-step explanation:

To find the volume of a pyramid, you can use the formula:

V = (1/3) * base area * height

In this case, the base is a square with sides of 600 feet, so its area is:

base area = 600 * 600 = 360,000 square feet

The height of the pyramid is given as 321 feet.

Now we can plug in the values into the formula:

V = (1/3) * 360,000 * 321

V = 38,400,000 cubic feet

Therefore, the volume of the Pyramid Arena in Memphis, Tennessee, is approximately 38,400,000 cubic feet.

An $800 deposit for 24 months earned $200 in interest.

SIMPLE INTEREST

NEED RATE & TOTAL VALUE

Answers

Answer:

x=12.5% (hope this right if not I am so sorry)

Answer Explanation:

let x%= annual interest rate

deposit = $800

interest earning period = 24 months = 24/12 years

interest earned = $200

so $200 = $800 * x /100* 24/12

200 = 800 * x/100 * 2

solve for x,

x = 12.5% per annum

Answer: X = 12.5%

The measures of the legs of a right triangle both measure 7 yards. What is the length of the hypotenuse? Round your answer to the nearest tenth.
A. 7 yards
B. 9.8 yards
C. 9.9 yards
D. 10 yards

Answers

Answer: 9.9 yards

Step-by-step explanation: Since we know that the legs of the right triangle both measure 7 yards, we can use the Pythagorean theorem to find the length of the hypotenuse, which is the longest side of the right triangle.

According to the Pythagorean theorem, the square of the hypotenuse equals the sum of the squares of the legs. In this case, we have:

c^2 = 7^2 + 7^2 c^2 = 49 + 49 c^2 = 98

To find the length of the hypotenuse, we need to take the square root of both sides of the equation:

c = √98

Using a calculator, we can find that √98 is approximately 9.9. Therefore, the length of the hypotenuse is approximately 9.9 yards.

The answer is C. 9.9 yards.

The answer is D. I hope this helps.

What is angle 2?

Answers

Answer: 145

Step-by-step explanation: 180 is a staight line so 180-35=145 would make sense

Angle 2 and the 35° angle are supplementary, which means they add up to 180°.

We can tell they are supplementary because they both make up one straight line.

35° + Angle 2 = 180°

Subtract 35° on both sides.

Angle 2 = 145°
