Answers

Answer 1
Answer: m=(y_1-y_2)/(x_1-x_2)

Line 1:
m=(5-3)/(1-0)\n m=(2)/(1)\n m=2\n\n\hbox{Point (0,3) is y-intercept so } b=3\n\n y=2x+3

Line 2:
m=(1-(-1))/(-1-(-2))\nm=(2)/(1)\nm=2\n\n1=2\cdot(-1)+b\n1=-2+b\nb=3\n\ny=2x+3

Allie answered 72% of the questions on her math test correctly. If she answered 18 questions correctly, how many questions were on the test?

Answers

Answer:

25 questions

Step-by-step explanation:

The answer to this question can be solved by setting up a proportion, or equivalent ratios (fractions).  Since we know that 18 questions was equal to 72% correct on the test, we can set up a proportion to find the total number of questions:

(72)/(100)=(18)/(x), where 'x' represents the total number of questions (or 100%) of the questions on the test.

Cross-multiply and divide:  72x = 18(100) or 72x = 1800

Divide both sides by 72:  72x/72 = 1800/72

Solve for x:  x = 25 questions

The speed limit on highways in Florida is 70 miles per hour write and solve an inequality to find how long it will take to travel 105 miles from Orlando to St Augustine if you travel at or below the speed limit

Answers

Answer:

The time is less than or equal to 1.5 hours

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x -----> the time in hours

The inequality that represent this situation is equal to

(105)/(x)\leq 70

Solve for x

Multiply by x both sides

105 \leq 70x

Divide by 70 both sides

105/70 \leq x

Rewrite the inequality

x \geq 105/70

x \geq 1.5\ hours

therefore

The time is less than or equal to 1.5 hours

Heather wants to buy a new refrigerator, but she only has room for one that is 18 ft3 or less. Which set of dimensions represent a refrigerator that Heather can buy?

Answers


As soon as I read the words "which set" in your question, I knew that
there's a list of choices on the sheet where you copied the question
from, but that you didn't copy the list along with the question.

All I can tell you is this: 
Find a choice where, when you multiply all three dimensions together,
the product is 18 ft³ or less.  That choice is a set of dimensions that
represents a refrigerator that will fit in Heather's kitchen. 

(For all I know, there may be more than one suitable choice on the list that
you didn't include with the question, so you'd better check all of them.)

Answer:

the answer is a

A) 2 ft. wide x 2.5 ft. long x 3 ft. tall  

B) 2 ft. wide x 2.5 ft. long x 4.5 ft. tall  

C) 2.5 ft wide x 3 ft. long x 4 ft. tall  

D) 2.5 ft. wide x 2 ft. long x 4 ft. tal

Step-by-step explanation:

2 ft. wide x 2.5 ft. long x 3 ft. tall because 2 x 2.5 x 3 = 15 ft3, which is less than 18 ft3.

-21 , 55 , -97 , 34 , 56 , -83 least to greatest?

Answers

Answer:

the answer is -97, -83, -21, 34, 55, 56

Step-by-step explanation:

The simple way to put it is negitives are backwards, the bigger the number the lesser it gets. So always put the highest negitive as least, hope this helps!

Answer:

-97, -83, -21, 34, 55, 56

Step-by-step explanation:

That's because think of a number line. The farther right the number is, the number will be smaller since it's a greater negative number. And the farther left the number is, the bigger the number since it is a greater positive number.
