Janie cut a round slice of watermelon into 3 equal pieces. What's the angle of each piece?

Answers

Answer 1

Answer: This would be 120 degrees each. Anything round is 360 degrees and if you cut that into three (which is dividing) it gives you 120

Answer 2

Answer: 120 degrees

you take 360 because that is the degrees all the way around the circle divide by 3 for the of slices which equals 120.

Consider the function represented by the equation x – y = 3. What is the equation written in function notation, with x as the independent variable?

Answers

We have an equation and we want to rewrite it as a function. The function will be: y = f(x) = -3 + x

So we start with the equation:

x - y = 3

And we want to write this in the form y = f(x) (because we want x to be the independent variable)

To do this, we just need to isolate y on one side of the equation.

x - y = 3

Now we subtract x in both sides:

x - y - x = 3 - x

-y = 3 - x

Now we multiply both sides by -1:

-1*(-y) = -1*(3 - x)

y = -3 + x

Then we have:

y = f(x) = -3 + x

This is the equation written in function notation.

When the question asks to write the equation "in function notation, with $x$ as the independent variable?", it simply is asking for the isolation of $y$ . This means that $y$ must be on its own side of the = sign with everything else on the other, because the dependent variable is being affected by the independent variable (hence the name "dependent").

The first step is to subtract $x$ from both sides, so you end up with $-y=3-x$ . This may look finished, but $y$ is still attached to a negative sign. To fix this, we must divide both sides by $-1$ to receive our final answer of $y=-3+x$ , which, when rearranged to be written in proper notation, reads as:

$y=x-3$

a triangular shape has an area of 70 square inches the height is 8 and three fourths write and solve an equation to find the length of the base

Answers

Area formula of a triangle is:
A = $(1)/(2) bh$
We know the area and the height, so substitute to find the base

A = 70 m²
h = 8.75 m or $8 (3)/(4)$ m (its the same thing)

70 = $(1)/(2)$ × b × 8.75
70 = 4.375b
Divide by 4.375 on either sides to isolate b
$(70)/(4.375) = (4.375b)/(4.375)$
4.375 and 4.375 cancels out

16 m = b

The base of this triangle is 16 m

Rene is going to the lake to visit some friends. If the lake is 60 miles away, and Rene is driving at 40 miles per hour the entire time, how long will it take her to get to the lake?

Answers

It would take Rene 1 1/2 hours to get to the lake.

We know that the lake is 60 miles away and divide it by her mph (40) and get 1.5 hours. If we did this as a fraction, it would be 60/40=1 20/40 or 1 1/2

Time = Distance/ speed
Time = 60/40
time = 6/4
=3/2
1 hour 30 m
