Austin correctly answered 92% of the questions on a geography quiz. Liz answered 47 of the 50 questions correctly. Which student got the most questions correctly.
(if you answer this may you please show your work)

Answers

Answer: Liz
To find the percent Liz got correct, you would do 47/50 to get 0.94. You would then move the decimal 2 places to get 94%.
94%>92%

Answer:liz scored better

Step-by-step explanation:

Liz scored better because how to find a percentage is dividing whatever two numbers you have by each other so it would be 47 / 50 which equals 0.94 then you times it by 100. Which would equal 94% which is better than a 92 which means Liz got the higher score

Christopher put 12 gallons of gas in her car. She uses one gallon for every 20 miles he drives.

a. Write an equation to represent the total amount of gas left in his car based upon how many miles she has driven.
b. Find the slope and y-intercept.

Answers

Answer:

Equation: y=(-1/20)x+12.

Slope: -1/20

Y-intercept: (0, 12)

Step-by-step explanation:

Let x=the number of gallons of gas in Christopher's car.

If we start with 12 gallons, we have the equation: y=(-1/20)x+12.

This equation is already in slope intercept form, so we see that the slope is -1/20, and the y-intercept is (0, 12).

Answers

Answer:

You do -3- 5=-8

Step-by-step explanation:

You do -3- 5=-8

Its just like 3+5=8

But it is in negative so it would be negative 8. But this only works in addition and subtraction. In division and multiplication it is different.

Answer:

It is equal to -8 cuz...

Step-by-step explanation:

(-3) - 5 is -8 how it's cuz a negative number minus a positive number it's gonna be a negative number.

but if a positive number minus a negative number it's gonna be a positive number.

and a negative number minus a negative number it's gonna be a positive number.

Matthew has lived in NY for 10 years. Matthew earns $17.25 per
hour. He worked 5.8 hours on Friday, 4.5 hours on Saturday, and 8
hours on Sunday. How much money did Matthew earn in all on Friday,
Saturday, and Sunday?

Answers

Answer:18.3

Step-by-step explanation: 18.3 because 5.8 + 4.5 =10.3 then add 8 its 18.3

Answer:

$315.68

Step-by-step explanation:

We would first add up all of the hours, so that would be 5.8+4.5+8 to get 18.3 hours. Since it is saying $17.25 per hour we would multiply 17.25 and 18.3 to get 315.675. But, because we are dealing with money, our answer would be rounded to the nearest hundredth. So, Mathew earned $315.68 on Friday, Saturday, and Sunday altogether.

Answer:

Step-by-step explanation:

Ok this is pretty simple. Slope intercept is by far the most simple way to write an equation given that it only has 2 pieces: the slope of the line and the value at which it crosses the y axis (so when x=0). Slope is usually represented by the varriable "m" and the y intercept is usually represented by the letter "b". (Don't ask me why they chose these 2 random letters. It's... it's just whatever... Go with it.) Thus, we have the equation y=mx+b. So anyways.. Slope is just the change in y divided by the change in x. To find this, we just take 2 random points on the graph, subtract the first y from the second y and divide that by the first x subtracted from the second x. Let's use (2,-9) and (4,-10) from this fun little graph you ever so generously provided for us.

I'm bad at transitions so here's the math:

(y2-y1)/(x2-x1)

((-10)-(-9))/(4-2)

-1/2 ------> Thats "m".

SOOO... the slope is -1/2. Cool. BUT WE ARENT DONE

The other thing we need is the y-intercept. You may find yourself asking "what is this... this THING... he speaks of?" Its where the line hits the y axis. Thats is. It's not that hard. In this case it's -8 so b=-8.

Now for the best part... LETS PLUG ALL THOSE DOOHICKEYS IN.

y=mx+b

m=-1/2

b=-8

y=-1/2x+-8-----> y=-1/2x-8

Answer:

<A = 115 degrees, <C = 50 degrees

Step-by-step explanation:

<A+<B+<C = 180 degrees

substitute with the given values: 4x - 13 + 15 + x + 18 = 180 degrees

Solve: x = 32 degrees

Substitute back in for <A : 4(32) - 13 = 115 degrees

Substitute back in for <C: 32 + 18 = 50 degrees

Identify the writing problem(s) in the following paragraph: The U. S. government defines poverty using an income-based threshold created in the early 1960s, which set the poverty level at 3 times the yearly cost of a basic food budget. Except for adjustments for inflation, it has remained unchanged since it was established despite the fact that today's families spend more on housing, child care, and health care than food. Social service workers spend much of their time trying to help families in need patch together a network of resources to meet their basic needs. Because the level of public assistance has not kept pace with other costs, this means they spend a greater proportion of their income on basic necessities that are not accounted for in the poverty equation.
