Answer:
y = 4
Step-by-step explanation:
If 3 is x than you can substitute x for 3. y = 3 + 1. Then when you add y = 4
y = x+1
y = 3+1
y= 4
that's how you solve it... Good luck

A city planner designs a park that is a quadrilateral with vertices at J(-1, 1), K (3, 3), L (5, -1), and
M(-1,-1). There is an entrance to the park at the midpoint of each side of the park. A straight path
connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane
represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to
the nearest whole number.
The total length of the paths is approximately
meters.
9514 1404 393
Answer:
83 m
Step-by-step explanation:
The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...
8.26(10 m) = 82.6 m ≈ 83 m
_____
The distance formula will tell you the distances are ...
AC = √(3² +1²) = √10
BD = √(5² +1²) = √26
The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

Answer:
a. circumference
b. area
c. area
d. circumference
Step-by-step explanation:
a. You are using the circumference formula to find the distance around a CIRCULAR track, if you used area, that would include the space in between the track as well. You are only trying to find the track line. ( you can draw a picture of a track and show what you are finding. )
b. You are trying to find the amount of area that the tiles make up in the circular floor, how much of the floor the tiles take up.
c. You are trying to find how much of the oil takes up of the WHOLE bottom of the frying pan.
d. Finding the circumference of your wheel can help determine the distance the car traveled. If you used area, it would not be useful.
Write each decimal as a percent and a fraction -0.04
Answer:
-4% -1/25
Step-by-step explanation:
To convert a decimal to a percentage, multiply it by 100.
-0.04 * 100 = -4
To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.
[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]
-4/100 simplified = -1/25 (because 4 goes into 100 25 times)
Find the value of x and
y if x-y=3 and 2x+3y=4
Answer:
Step-by-step explanation:
Given :
x-y = 3 equation(i)
2x + 3y = 4 equation(ii)
Now,
x - y = 3
x = 3 + y
substitute the value of x in equation (ii)
2x + 3y = 4
2(3 + y) + 3y = 4
6 + 2y + 3y = 4
6 + 5y = 4
y = -2/5

When you round a number, what should you do with
the digits to the right of the place to which you
are rounding?
Answer:
In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).
Step-by-step explanation:
When you square or cube a negative number is it still negative or does it become positive?
Example:
(-4)^{2}

Find the distance between X (-3,8) and Z (-5,1). Round to the nearest tenth if necessary.
9514 1404 393
Answer:
7.3
Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-5-(-3))² +(1 -8)²) = √((-2)² +(-7)²) = √(4+49) = √53
d ≈ 7.28011 ≈ 7.3 . . . units
XZ ≈ 7.3

with work please
9514 1404 393
Answer:
-1/2048
Step-by-step explanation:
The Order of Operations tells you to evaluate each of the exponential expressions first. Then you do the division.
= (1/32) / (-64)
= -1/(32·64) = -1/2048
__
You can also rewrite the expression in terms of powers of 2.
2^-5/-4^3 = -1/((2^5)(2^2)^3) = -1/(2^5×2^6) = -1/2^11
= -1/2048
_____
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)^c = a^(bc)
(a^b)(a^c) = a^(b+c)
4 = 2^2
2^5 = 32

x is less than or equal to 3. What is the interval notation
Answer:
Step-by-step explanation:
Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .
The statement in the mathematical form will be x ≤ 3. Then the inequality in the interval notation will be [3, ∞).
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.
x is less than or equal to 3.
Convert the statement into a mathematical inequality. Then we have
x ≤ 3
The statement "x is less than or equal to 3" in the mathematical form will be x ≤ 3.
Thus, the inequality in the interval notation will be [3, ∞).

Let's suppose we conduct a hypothesis test about the mean value of something, and determine that we should reject the null hypothesis. What does that mean?
a. Our hypothesized mean has been proven incorrect
b. The difference between our sample mean and our hypothesized mean was most likely due to random chance.
c. The difference between our sample mean and our hypothesized mean was statistically significant.
d. The difference between our sample mean and our hypothesized mean was not statistically significant.
Answer: Choice C.
The difference between our sample mean and our hypothesized mean was statistically significant.
=========================================================
Explanation:
The null hypothesis is always set up in a way to state the following: "The mean mu is equal to some value"
The mu is a greek letter often used as the population mean symbol. The actual symbol itself looks like this [tex]\mu[/tex]
When we reject the null, we reject the idea that the mu is whatever stated value we said in the null. So we must go with the alternative hypothesis.
The sample mean we computed (xbar) is different enough from the mu value that we're able to make such a rejection. We consider this statistically significant, which is another way of saying that such a difference is not simply due to random chance.
The Metropolitan Company sells its latest product at a unit price of $7. Variable costs are estimated to be 20% of the total revenue, while fixed costs amount to $6,300 per month. How many units
should the company sell per month to break even, assuming that it can sell up to 5,000 units per month at the planned price?
9514 1404 393
Answer:
1125
Step-by-step explanation:
The "contribution margin" of each product is 80% of its unit price, or $5.60. In order to break even, the total contribution margin must match the fixed costs.
$5.60n = $6300
n = 6300/5.6 = 1125
The company should sell 1125 units per month to break even.

solve for y:
x^3 + (1/a)y= xy+9
Step-by-step explanation:
[tex] {x}^{3} + ( \frac{1}{a} )y = xy + 9[/tex]
[tex]x {}^{3} + \frac{y}{ay} = xy + 9[/tex]
[tex]x {}^{3 } = xy + 9 - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = xy - \frac{y}{ay} [/tex]
[tex] {x}^{3} - 9 = y(x - \frac{1}{a} )[/tex]
Divide both sides by x-1/a
[tex] \frac{x {}^{3} - 9}{x - \frac{1}{a} } = y[/tex]
