Answer: 2.5

Step-by-step explanation: to find the unit rate/slope we need to pick 2 points and subtract the y's and x's

i picked (2, 5) and (1, 2.5)

5 - 2.5 = 2.5

2 - 1 = 1

2.5/1 = 2.5

2.5 is the slope

Answer is -11.95

You can give the unknown value as x to make things easier

( x + 1.75 ) / 2 = -5.1

Find the value of x:

x + 1.75 = –5.1 x 2
x + 1.75 = -10.2

x = -10.2 – 1.75
x = -11.95

Not sure abt the simplified mixed number sorry tho -11.95 gives an answer of -239/20 on a calc

Does anyone have any ideas for multiplying 249 times 398 quickly and mentally? Everything online is too complex.

Answers

Answer:

So, the first solution is a calculator but sometime we don't have a calculator so, do

200 X 300 = A

40 X 90 = B

9 X 8 = C

then add just do multiplication from there like

A + B = D

D + C = E

Then your finally answer would be E

Hope that helps that's the way I do math quick in my head

(Btw the answer to 249 X 398 = 63,672 )

First do 2times3 and then add 4 0’s because they are in the hundreds place and each of them have 2 0’s then do 9times4 and add 2 0’s to the answer and then do 9times8 add up all the answers :)

Regina is buying a new car. She sees two advertisements in the paper for the same car at two different prices from two different dealerships. Both dealers are offering a simple-interest loan for the price of the car.

A photo of car includes two ads. Ad A shows the vehicle priced at twenty-four thousand two hundred dollars at six point five percent interest and an unknown number of years. Ad B shows an unknown price, at a five point three percent interest over nine years.

Part A

Regina calculates that to buy the car in Ad A, the loan would ultimately cost her $41,503. Over how many years is the loan in Ad A to be paid back?

Part B
Regina calculates that to buy the car in Ad B, the loan would ultimately cost her $38,402. What is the price of the car offered in Ad B?

Part C
In either case, Regina would be paying back the dealer in equal monthly installments over the lifetime of the loan. What would her monthly payments be if she bought the car shown in Ad A? What about if she bought the car shown in Ad B?

After sales tax, A $96 watch costs $101.28. what is the sales tax percentage?

Answers

Answer:

i think it's 5.5 percent

Answer: The answer is 5.5% sales tax percentage

Step-by-step explanation:

First, subtract the total amount by the original amount

$101.28-$96= 5.28

Next, you would divide 5.28 by 96

5.28/96 = 0.055

The final part in which to get the answer is to multiply 0.055 with 100%

0.05·100= 5.5%

ΔABC is an isosceles triangle with AB = AC, D is the midpoint of BC and

I kinda have a problem with triangles and congruency....little help please ?

Answers

Step-by-step explanation:

Okay, so the triangle would look something like this:

see the image attached

Since AB=AC, which is given; <ABD = <ACD, because they are the angles opposite from the congruent sides of the isosceles triangle; and <ADB=<ADC, as AD is the bisector*; ΔABD ≅ ΔACD using SAA/AAS (side-angle-angle) congruencey.

*If the bisector of an angle in a triangle meets the opposite side at its midpoint, then the triangle is isosceles, and vice versa

A summer camp cookout is planned for the campers and their families. There is room for 200 people. Each adult costs $4, and each camper costs $3. There is a maximum budget of $750. Write the system of inequalities to represent this real-world scenario, where x is the number of adults and y is the number of campers. x + y ≤ 200 4x + 3y ≤ 750 x + y ≤ 750 4x + 3y ≤ 200 x + y ≤ 200 3x + 4y ≤ 750 x + y ≤ 750 3x + 4y ≤ 200

Answers

Answer:

I think its A

Step-by-step explanation:

The required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.

What is inequality?

Inequality is a non-equal relation between two expressions involving variables and constants.

The sign of the inequality can be, less than (<), greater than (>), less than or equal to (≤), or greater than or equal to (≥).

How to solve the question?

In the question, we are asked to write the system of inequalities to represent the given scenario, where x is the number of adults and y is the number of campers.

We are informed that there is a room for 200 people.

Thus, the total number of people, that is, the number of adults + the number of campers, or, x + y should be less than or equal to 200.

This gives us an inequality:

x + y ≤ 200.

We are informed that the cost of an adult is $4 and the cost for a camper is $3, and the total budget is $750.

Thus, the total cost, that is, the cost of all adults + the cost of all campers, or, 4x + 3y should be less than or equal to 750.

This gives us an inequality:

4x + 3y ≤ 750.

Thus, the required system of inequalities is x + y ≤ 200 and 4x + 3y ≤ 750. Hence, the first option is the correct choice.

(MC)Ginny the Dog: A Hero Among HeroesHeroes come in many shapes and forms, but they all do uncommon things in unusual situations. They stand out. We've all heard stories of hero dogs that save their owners. One dog saved his owner by fighting off an alligator. Another woke his sleeping family when a fire broke out in its home. Still others rescue injured or needy people in dangerous situations. One dog even managed to call 911 when his owner suffered a seizure. But one dog, named Ginny, performed heroic acts on a regular basis, not just once or twice in unusual situations. Because of her kindness, many lives were saved.Ginny the dog was adopted by her owner from an animal shelter in 1990. Within days of bringing her home, her owner discovered that Ginny seemed to be able to find cats in distress. On her daily walks, Ginny would often find abandoned, trapped, or endangered kittens or cats that needed rescuing. In one such episode, Ginny found a group of kittens trapped in a pipe. She managed to let her owner know, by scratching and barking at the pipe, that something needed her help. Because of Ginny, all the kittens were saved.Almost daily, Ginny would find cats that needed rescuing or, in some cases, a little love. Ginny's owner reported that when Ginny saw a cat on their walks, she would pull away from her leash and run after the cat. Instead of chasing cats like most dogs, Ginny would nuzzle and lick them, giving them comfort. Because of Ginny, her owner soon found he was caring for hundreds of wild neighborhood cats. In addition, Ginny pushed her owner to adopt more than 20 cats, most of whom had permanent injuries or special needs."When we would go to the pound to drop off donations," her owner said, "Ginny always found the cat that was blind or deaf or hurt in some way. She would sit down in front of the cat's crate and not move until we brought it home."What makes a dog behave in such a kind way? Some believe Ginny had a very strong mothering instinct. But how could she tell when a cat was deaf? How did she know which cats needed love and attention? Regardless of how she did it, Ginny rescued hundreds of cats in her life and set an example we all can follow.What is the main purpose of including the story of Ginny wanting to care for blind or deaf cats? To create awareness of the need to give to animal shelters To explain the owner's role in training Ginny To show that Ginny was aware of cats with special needs.
