Answers

Answer 1

Answer:

4^7

Step-by-step explanation:

4^5 × 4^9/4^7

When you’re multiplying exponents with the same bases, add powers together, so...

4^5 × 4^9 = 4^14

= 4^14/4^7

When you're dividing exponents with the same bases, subtract powers from each other, so...

4^14 - 4^7 = 4^7

Therefore, 4^7 is your answer! :)

Answer 2

the answer is 4^7 :)

Write the following expression in simplest form.

(3 + 16.4a) − (9 + 5.7a)

22.1a + (−12)
1.07a + (−12)
22.1a + (−6)
10.7a + (−6)

Answers

Answer:

10.7a + (−6)

Step-by-step explanation:

Let's simplify step-by-step.

3+16.4a−(9+5.7a)

Distribute the Negative Sign:

=3+16.4a+−1(9+5.7a)

=3+16.4a+(−1)(9)+−1(5.7a)

=3+16.4a+−9+−5.7a

Combine Like Terms:

=3+16.4a+−9+−5.7a

=(16.4a+−5.7a)+(3+−9)

=10.7a+−6

Option D is correct. The expression in its simplest form is: 10.7a - 6.

Let's simplify the given expression:

(3 + 16.4a) − (9 + 5.7a)

Distribute the negative sign to the terms inside the second parentheses:

(3 + 16.4a) − 9 − 5.7a

Combine like terms:

(16.4a - 5.7a) + (3 - 9)

Perform the subtraction and subtraction of coefficients:

(16.4a - 5.7a) + (-6)

Simplify the expression:

(10.7a) - 6

So, the expression in its simplest form is: 10.7a - 6. Option D is correct.

This is a scale drawing of a deck. The actual deck has a perimeter of 120 ft. Draw another scale drawing of the deck using the scale 15 ft to 1 unit from the deck to the drawing. Explain your reasoning.

Answers

The scale 15 ft to 1 unit from the deck to the drawing will give a perimeter of 8 units.

How to calculate the scale?

From the information, the actual deck has a perimeter of 120 ft.

Therefore, another scale drawing of the deck using the scale 15 ft to 1 unit from the deck to the drawing will be:

= Normal perimeter / Scale used

= 120 / 15

= 8

Therefore, the scale 15 ft to 1 unit from the deck to the drawing will give a perimeter of 8 units.

Solve the following word problem. A fish is swimming at −10.8 meters, or 10.8 meters below sea level. Every 2 minutes it descends another 1.5 meters. How long will it take for the fish to reach a depth of −37.8 meters? Show your work and write a sentence to explain what your answer means.

Answers

By forming equation, we have solve the given problem. Fish will take 36 minutes for the fish to reach a depth of −37.8 meters.

What is Equation?

Two or more expressions with an equal sign is called as Equation

Given that

A fish is swimming at −10.8 meters, or 10.8 meters below sea level.

Every 2 minutes it descends another 1.5 meters.

We have to calculate how long it takes for the fish to reach depth of −37.8 meters.

By given data, let us find the difference of 37.8 and 10.8.

37.8-10.8

The difference value of 37.8 and 10.8 is 27

Now divide 27 by 1.5.

27 divided by 1.5

We get 18

Now for every 2 minutes it descends, so

18 x 2=36minutes.

Hence 36 minutes fish will it take for the fish to reach a depth of −37.8 meters.

A rural mail carrier logged the mileage on the odmeter at the start of th mail route as 31,500 miles. After 6.5 hours the carrier returned the truck recorded the mileage at 31,713 miles what was the average velocity of the mail truck

Answers

Answer:

Okay, So rural mail carrier started the day with 31,500 miles 6.5 hours later has 3, 31,613 miles. So if you want the average velocity of the mail truck over this day, we're going to start, we're going to find basically the treat the average velocity as a slope. So we're gonna do is we're gonna do the final three hoops, 31,713 -231500. This will be the total distance that they traveled And that happened over 6.5 hours. So 31,613 -31500 is going to give me 213 over 6.5 hours. So what this represents is The truck went 213 miles Over the course of 6.5 hours. So again, that's miles over ours. So I take that value Divide by 6.5 and I get Average velocity of 30 32 Point that's just a 77. Okay. And again, because I had it set up as miles over hours, this is gonna be MPH. So this is where we find the average velocity of something. We're looking at, what was it at the very end. Now, the truck went faster and slower than this speed at times, But in the end because it covered two and 13 miles in 6.5 hours, The average velocity was 32.77 mph

Step-by-step explanation:

32.77 mph is the answer

Which expression is equivalent to quantity negative three and one third times d plus three fourths end quantity minus quantity three and five sixths times d plus seven eighths end quantity?

one half times d minus one eighth
one half times d minus one and five eighths
forty three over 6 times d minus one eighth
negative forty three over six times d minus one eighth

Answers

The simplification form of the expression -3 1/3 d + 3/4 - (3 5/6 d + 7/8) is -(43/6)d - 1/8 option (D) negative forty-three over six times d minus one eighth is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that:

Quantity negative three and one-third times d plus three-fourths end quantity minus quantity three and five-sixths times d plus seven-eighths end quantity

As we know, linear expression can be defined as the relation between two variables, if we plot the graph of the linear expression we will get a straight line.

If in the linear expression, one variable is present, then the expression is known as the linear expression in one variable.

The word expression can be expressed mathematically,

= -3 1/3 d + 3/4 - (3 5/6 d + 7/8)

= -10d/3 + 3/4 - 23d/6 - 7/8)

= -(43/6)d - 1/8

Thus, the simplification form of the expression -3 1/3 d + 3/4 - (3 5/6 d + 7/8) is -(43/6)d - 1/8 option (D) negative forty-three over six times d minus one eighth is correct.
