What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?

Don’t put a link.

Answers

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

2 1/4x - 6 3/10

trying to cheat on a performance matter test but the answer is the last one -3 1/8 x + 6 3/10

If you are given the diameter of a circle, how can you find the radius?

Answers

Answer:

Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of the circle is 3.5 feet. You can also use the circumference and radius equation.

Step-by-step explanation: that's it

You divide the diameter by 2 to find the radius. If you want to find the diameter then you multiply the radius by 2

Find the value of x and m∠HKL.

Answers

Answer:

x = 25 degrees   ∠HKL = 102 degrees

Step-by-step explanation:

The whole thing equals 180, since it is a straight angle

The value of HKL is 180 - 78 = 102

So that means 4x + 2 = 102

Subtract 2 from both sides:

4x = 100

Divide both sides by 4:

x = 25

Colby graphed a scatter plot of student exam scores (y) and the number of hours each student had slept the night before the exam (x). She drew the trend line and calculated its equation to be y=92x+60

What is the predicted score for a student who slept 6 hours the night before the exam?

Answers

Answer: 612

Step-by-step explanation:

Substitute the value 6 (hours) in the equation and solve.

Y = 92x+60

Y = (92*6)+60

Y=552+60 = 612

Based on your data, what is the experimental probability that the family has two dogs or two cats? (Heads= dogs and tails=cats)

My table:

Heads, Heads
15
Heads, Tails
9
Tails, Heads
16
Tails, Tails
10
Total
50
Also, please explain your answer.

Answers

Answer:

Two dogs: 30%

Two cats: 20%

Two dogs OR two cats: 50%

Step-by-step explanation:

Since the total is 50, we have to multiply all the numbers by two. The total will then 100, so one unit in each category will represent one percent. For example, 15 x 2 = 30, so the chance for two dogs is 30%.

If your question meant two dogs OR two cats as a single probability - not the individual probabilities of two dogs and two cat - then it is 50%, because 30 (two dogs) + 20 (two cats) = 50 (two dogs OR cats). I hope this helps! Sorry if my explanation doesn’t make lots of sense, I’m typing this off my phone. Feel free to ask any questions!

Answers

Answer:

Nonlinear, linear, nonlinear(Please excuse my grammar)

Step-by-step explanation:

A is nonlinear because it is an exponential function. As we add more X inputs, the change is the Y coordinates increase by a greater and greater amount. As an example, X=1, then Y=3, X=2, then Y=9, etc. B is linear because it is a horizontal line. No matter the X input, Y will remain the same because it is given: y=-5. C is nonlinear because it is a quadratic function. In any quadratic function, the line reaches a vertex before changing directions therefore, not forming a line.
