The difference between two numbers is 8. The lesser number is a . Write an expression for the greater number.

Answers

b-a=8
b is the greater number; b>a
So, b=a+8

Final answer:

The expression for the greater number is a + 8, which is found by adding the given difference of 8 to the lesser number a.

Explanation:

The student has given us an equation to work with: The difference between two numbers is 8, and the lesser number is known as a. To find the expression for the greater number, we simply need to add the difference to the lesser number. Therefore, the greater number can be expressed as a + 8.

Let's illustrate this with an example. If the lesser number, a, is 5, then to find the greater number, we add the difference of 8 to 5, giving us 13 as the greater number.

given tan theta =4/3 and sin theta =-4/5, find cos theta

Answers

given tan theta 4/3 and sin (-4/5), find cos theta
cos theta-3/5

Given tanθ = 4/3 and sin θ =-4/5, based on the Pythagorean identity the cos θ is  3/5.

How do we find the values of  cos θ?

The sine, cosine, and tangent of an angle are related by the Pythagorean identity sin²(θ) + cos²(θ) = 1.

This means we can solve for cosine given the sine value:

cos²(θ) = 1 - sin²(θ)

We know that sin(θ) = -4/5, so:

cos²θ) = 1 - (-4/5)²

cos²(θ) = 1 - 16/25

cos²(θ) = 9/25

Taking the square root of both sides,

we find that cos(θ) could be ±3/5.

However, we need to consider the quadrant in which theta is located. Since the tangent of theta is positive (4/3) and the sine of theta is negative (-4/5), theta must be in the fourth quadrant (where sine is negative and tangent is positive). In the fourth quadrant, cosine is positive.

Therefore, cos(theta) = 3/5.

Answers

Basically, move the decimal dot 10 spaces to the right.

I can do this in my head by thinking like this: There are three numbers after the decimal, so I only need to add 7 zeros.

Then I would right it out like this: 9125

then add 7 zeros: 91250000000
.....................................1234567

Hope this helps, and May the Force Be With You!

-Jabba

Final answer:

The number 9.125 x 10¹⁰ in standard form is 91,250,000,000.

Explanation:

The number 9.125 x 10¹⁰ in standard form is written as 91,250,000,000.

The documentation "E10" addresses increasing the number by 10 raised to the force of 10. For this situation, "E10" signifies we really want to increase 9.125 by 10¹⁰.

To work out this, we move the decimal guide 10 spots toward the right, bringing about an extremely huge number:

9.125 E10 = 9,125,000,000

In this way, 9.125 E10 in standard structure is 9,125,000,000.

Malik borrowed $8,000 to buy a new boat. He will pay off the loan after 4 years by paying back the principal plus 6.5% simple interest. How much will Malik pay back altogether?
A. $520 B. $2,080 C. $8,000 D. $10,080

Answers

the answer is D - 10, 080

Answer:  D. $10,080

Step-by-step explanation:

The formula to find  the simple interest is given by :-

[tex]S.I.=Prt[/tex], where P is principal amount , r is rate of interest ( in decimal ) and t is time period.

Given : Principal amount = $8,000

The rate of interest = 6.5% = 0.065

Time period= 4 years

Then , the simple interest will be :-

[tex]S.I.=8000\times0.065\times4=2080[/tex]

Hence, the amount which Malik pay back altogether = [tex]P+S.I.=8000+2080=\$10,080[/tex]

A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi How much faster does the fish swim than the boy in yards per minute?

Answers

Okay. A boy swims 4.4 feet per second. There are 3,600 seconds in one hour. 4.4 * 3,600 is 15,840 feet in one hour. 15,840/5,280 is 3. The boy swims at 3 miles per hour. The fish swims at 12 mph. To find out how much faster the fish is than the boy in yards, we need to convert the measurements into yards and divide them per minute. Mind you, there are 1,760 yards in 1 mile. 12 * 1,760 is 21,120. 21,120/60 is 352. The fish swims 352 yards per minute. 3 * 1,760 is 5,280. 5,280/60 is 88. The boys swims 88 yards per minute. Now, we must subtract both numbers to see how much faster the fish swims. 352 - 88 = 264. There. The fish swims 264 yards faster per minute, than the boy.

The speed by which the boy swims as fast as the fish will be 528.01 yards per minute.

What is unit conversion?

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

It is given that a fish swims at a speed of 12 miles per hour and a boy swims at a speed of 4.4 feet per second.

As we know,

1 mile per hour = 29.3333 yards per minute

12 miles per hour = 12 × 29.3333 yards per minute

12 miles per hour = 351.99 yards per minute

1 feet per second = 20 yards per minute

4.4 feet per second = 44 × 20 yards per minute

4.4 feet per second = 880 yards per minute

The difference in their speed is,

=  880 yards per minute - 351.99 yards per minute

= 528.01 yards per minute

Thus, the speed by which the boy swims as fast as the fish will be 528.01 yards per minute.

answer is A

Square root helps to find the factor of a number which when multiplied by itself gives us the number. The value of √1.69 is √1.3.

What is square root?

Square root can be defined as the process of finding a number which is a factor of a number when multiplied by itself to get a number.

In order to evaluate the value of √1.69, we will convert decimal value 1.69 into a fraction, therefore, the fraction can be written as,

[tex]1.69 = \dfrac{169}{100}[/tex]

Now, using this equivalent value of 1.69, the evaluation can be written as,

[tex]\sqrt{1.69}\\\\= \sqrt{\dfrac{169}{100}}[/tex]

Further, using the exponential property the value can be written as,

[tex]= \sqrt{\dfrac{169}{100}}\\\\\\={\dfrac{\sqrt{169}}{\sqrt{100}}}\\\\\\=\dfrac{13}{10}\\\\=1.3[/tex]

Hence, the value of √1.69 is √1.3.

Caroline drove 350 miles to the beach the trip took her 5 1/4 hours what was her average speed in miles per hour?

Answers

1.111 repeating miles an hour
Use the formula d = rt to figure this out, where d is distance, r is the rate of travel, and t is the total amount of time taken to travel the distance, d.

So the equation would be 350 = 5.15r (I converted 5 1/4 to a decimal to make it easier.) Now we simply need to solve for the variable r to get the final answer.

Once the equation is solved for r, the final answer is ABOUT 68 mph. So, Caroline drove at an average speed of 68 miles per hour.

QUESTION 10:

- The long edge of the paper is 11 inches long
- The frame is 4 long edges long
4 times 11 = 44 inches.
Now for the feet calculation!
- 1 foot = 12 inches
44 inches divided by 12 inches is 3 2/3 feet.

- First, convert 3 yards into feet.
- 1 yard = 3 feet
- 3 yards = 9 feet
- 9 feet plus 2 feet = 11 feet.
