The temperate in Anchorage, Alaska at 9am was at -2°F. At 9pm the temperature decreased 7°F. Write an expression that represents the difference between the temperature from 9am to the resulting temperature at 9pm. How do I write the expression?

Answers

Answer 1
T=(-7/12)t-2

Im calling temperature T and time t for our equation but they can just as easily be Y and X

In 12 hours time the temp decreased 7 degrees so to get the slope we went down 7 and over 12 making it -7/12 (since we went down)

The at the starting point of t=0 it’s already -2 F making that our “y intercept” T intercept in this case

y=mx +b

In our case y=T x=t m=-7/12 and b= -2
Replace them to get
T=(-7/12)t-2

Terry is throwing a surprise party. She has invited 31 people. She is buying party favors that come in packages of 5. How many packages does Terry need to order so that she has enough for each guest to have one? ​

Answers

Answer:

Terry needs to buy 7 packages

Step-by-step explanation:

Terry has invited 31 people, meaning she needs 31 party favors

If they come in groups of five, we have to find how many packages(of 5) equal 31. Because 5 does not evenly multiply into 31, (it fits evenly inti 30) we have to add an extra package, meaning she will need 7 packages because 7×5 is 35, which is enough for each guest

Some of the problems cities experienced as a result of rapid growth in the late 1800s included disease, crowded living spaces, and __________.

Answers

Answer:

poverty

Step-by-step explanation:

lack of workers makes no sense bcs the population was only increasing

limited recreational options don't make any sense either bcS that is not affected by population

and lack of transportation doesn't make any sense bcs it was the 1800's and people walked

Answer: B) Poverty

=====================================================

Explanation:

Unfortunately many people did not have much money to afford the basics such as a decent home and food to put on the table. Even if the person was working, they may be in a very dangerous job that provides little pay. An example could be a factory worker. So this is why choice B is the answer.

There were definitely plenty of able-bodied people, so there wasn't a shortage of workers. This allows us to rule out choice C. There also wasn't a lack of transportation since people either lived close and walked, or they had modes of transport such as rail or bike. Cars were starting to show up in the very late 1800s, but it wouldn't be until the early 1900s is when they became more commonplace. So we can rule out choice D.

Choice A can be ruled out since there were many recreation options such as going to the park or beach, or going to plays or classical music concerts, to name a few ways to have fun.

Find the area of the triangle below. Be sure to include the correct unit in your answer. 13 yd 9yd 4yd​

Answers

Answer:

54.84 yd^2

Step-by-step explanation:

1/2BH

1/2(13)(8 7/16) = 54.84

Answer:

18.

Step-by-step explanation:

4yd is on the bottom.

9yd is on the left.

13yd is on the right.

The area for a triangle is [tex]\frac{1}{2} * b * h.[/tex] We add the numbers into the formula.

[tex]\frac{1}{2} *4*9 = 18.[/tex]

We do not use 13, because it is only going from one corner to the opposite corner. So, the answer is 18.

A right triangle has legs with lengths 61 cm and 60 cm. What is the length of the hypotenuse

Answers

For this, use Pythagoras which is a^2 + b^2 = c^2.
61^2 + 60^2 = 7321
Now square root your value, 85.6

The answer is 85.6 cm

Answer:

We gotta use Pythagorean theorem, fellas!

a^2 + b^2 = c^2

c^2 is the hypotenuse being squared.

a is a leg of a right triangle

b is another leg of a right triangle

------------------------------------------------------

we will use 61 for a

we will use 60 for b

a^2 + b^2 = c^2

61^2 + 60^2 = c^2

3721 + 3600 = c^2

7321 = c^2

[tex]\sqrt{7321}[/tex] = c (remember that c is hypotenuse)

c is rounded to 85.56 cm or 85.563 cm or 86 cm (depends on how the question wants the answer to look like)

ANSWER: 86 cm, 85.56 cm, or 85.563 cm

B - 3 and 4 years
C - 9 and 10 years
D - 5 and 6 years

Answers

Answer:

1) A

2) A

3) C

4) D

Step-by-step explanation:

Exponential decay is for 1) because as the years pass, the depth decreases.

2) if it decreases by 2%, this means 100%-2%= 98%=0.98.

3) same as 2).

4) The equation for this situation can be represented with y=30(0.98)^x. when x is between 5 and 6, the depth of the lake is approximately 26.7 meters. So, it takes around 5 to 6 years for the depth of the lake to decrease to 26.7 meters.

Answer:

F; A translation of 6 up and 4 left and a reflection across the x-axis

Step-by-step explanation:

Here, we want to perform the translation that would move S to S’

to do this, we can have a subtraction

For 1 to move to -3 on the x-axis;

it means there is a leftward shift of upto 4 units

For -8 to turn to 2;

this is positive; there is a vertical upward translation of upto 10 units on the y-axis

This option is not directly available; thus we have to factor the reflection

if we reflect on the x-axis, the y-axis value becomes negated; if we reflect on the y-axis, the x-value becomes negated

The correct answer is thus;

A translation of 6 up and 4 left, followed by a reflection across the x-axis

On Saturday 1164 people saw movie at the up city theater on Sunday 1576 people saw the same movie there were a total of four movie screens with the same number of people in the audience about how many more people watched each screen on Sunday

Answers

Answer:

Step-by-step explanation:

The computation of the number of more people watched each screen on sunday is shown below:

= Sunday - saturday

= 394 - 291

= 103 more people

hence, the number of more people watched each screen on sunday is 103
