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.
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.
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.

so,
(5)+2=_
well, 5+2 is 7
so on the _ you will write 7
Answer: The answer for 4 is 7 and for 6 it's 14 and the slash means to divide
Step-by-step explanation: (14-9)+2 first solve the parentheses then the outside so 14-9 would be 5 and you would 5+2 which then equals 7. then for the second we do the same solve within the parentheses 8+6 equals 14/ 2-1 then we subtract and have 14/1 and anything divided by 1 stays the same which equals 14.

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
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

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)
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.
