2. 60
3. 40
4. 20

Answers

1.50 5/9(122-32)=5/9(90)= 50

Answer: 50

Step-by-step explanation:

5/9 (f-32) if f = 122 you take 122 and subtract 32 because of order of operations and now you have 5/9 (90) and then you multiply 5/9 times 90 and you get 50

David is running a 500 m sprint. so far he has run 300 m. what fraction of the spirit does he have left?
?
__
?
what percent?________%

Answers

40 percent is left to run

Answer:

200/500=2/5

40%

Step-by-step explanation:

If the total distance of the sprint is 500m and he's already run 300m, so subtract 500-300 which equals 200.

Then put it in fraction form 500 being the total distance needing to be traveled in all will be your denominator and 200 being the distance left to be traveled will be your numerator. 200/500

Then simplify=200/500 divided by 100/100 equals 2/5.

Then to get it to a percentage divide 2 by 5 which equals  .40

Then convert to a percentage 40%

In Science class, Mrs. Olson had 30.6 pounds of metamorphic rock. Mrs. Olson had to divide the rocks into 9 different containers for a class assignment. If the rocks are equally divided into 9 different containers, how many pounds of rock will be in each container?

Answers

The answer is 3.4 because 30 can’t be divided equally into 9, reason being that 9 x 30 = 270 which doesn’t make sense, so you have to divide 30 equally into 9 parts then turn it into a ratio.

the answer is most likely 3.4

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

Why does the sum of the two given angles equal 180°? (2x+1)+(x-7)=180

Answers

Answer:

because its a straight line

Step-by-step explanation:

Answer:

Since the sum of the angles is 180 degrees and each angle is represented by the respective algebraic expressions, then to find the value of x, just add the expressions up, set that sum equal to 180, and solve for x. So, (2x-7)+(x+25)+(3x+12)=180 is our equation. Now we just simplify and solve for x.

(2x-7)+(x+25)+(3x+12)=180

6x+30=180 b/c 2x+x+3x=6x and -7+25+12=30.

6x=150 subtract 30 from both sides of the equation

x=25.

g÷ 5/8 =1
basically its asking what divided by 5/8 = 1

Answers

Answer:

5/8 divided by 5/8 = 1

Step-by-step explanation:

First, you know that dividing by a fraction is the same as multiplying by its reciprocal, so dividing by 5/8 is the same as multiplying by 8/5.

[tex]g / 5/8 = 1\\g * 8/5 = 1[/tex]

Now, multiply both sides by 5 to get rid of the fraction.

[tex]8g = 5[/tex]

divide both sides by 8

[tex]g = 5/8[/tex]

It’s asking you to what 5/8= 1 to do basically you have to multiply the 8 to both sides and then you probably will get your answer but I’m not to sure

5-4t = 6

Answers

The answer is negative one fourth.

t = 1/4

-----

First, rearrange the subtraction problem

5 - 4t = 6 is the same as -4t + 5 = 6

-----

Next, subtract 5 from both sides

-4t + 5 - 5 = 6 -5

This is known as the Subtraction property of equality.

-----

Then, since 5-5 is 0 and 6-5 is 1  

-4t = 1

-----

Then, you would divide that so

-4/-4 = 1/-4

-----

So your answer would be

1/4!

Finding the slope:
Identify the slope on the graph below.​

Answers

3/2 is the slope of the graph

Answer:

[tex]\frac32[/tex]

Step-by-step explanation:

Hello!

Slope can be calculated by [tex]\frac{Rise}{Run}[/tex].

The Rise of the graph is how much the graph changes in y between two points.The Run of the graph is how much the graph changes in x between two points.

I'll pick points (0,-2) and (2,1) on the graph.

You can see that the difference in y (-2 and 1) is 3 units.

The difference in x (0 and 2) is 2 units.

Put it into the format and you get a slope of [tex]\frac32[/tex].
