Answer:
composite
Step-by-step explanation:
composite- is defined as the whole numbers that have more than two factors. whole numbers that are not prime are composite numbers, because they are divisible by more than two numbers. As shown in the image.
Larry is 4 times as old as his niece. Four years ago he was 6 times as old
as his niece was then. Find each of their ages now
9514 1404 393
Answer:
Larry: 40niece: 10Step-by-step explanation:
Let n represent the current age of the niece. Then 4n is Larry's current age. 4 years ago, the relationship was ...
6(n -4) = 4n -4
6n -24 = 4n -4
2n = 20
n = 10
Larry is 40; his niece is 10.

30 POINTS!!! Find the area of each shaded region to the nearest hundredth. Show ur work
Answer:
[tex] 25.74 \: {m}^{2} [/tex]
Step-by-step explanation:
For parallelogram:
Base (b) = 6 + 3 = 9 m
Height (h) = 6 m
For circle:
Diameter = 6 m
Radius (r) = 6/2 = 3 m
Area of shaded region = Area of parallelogram - Area of circle
[tex] = bh - \pi {r}^{2} \\ \\ = 9 \times 6 - 3.14 {(3)}^{2} \\ \\ = 54 - 28.26 \\ \\ = 25.74 \: {m}^{2} [/tex]
PLEASE HELP!!
A plane is going to fly 400 miles at a planned speed of 570 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time T, in hours, of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
T(w) = 400/570 - W
a) What does T(150) mean in this situation?
b) At what value of w does the graph have a vertical asymptote? Explain how you know and what this asymptote means in the situation.
Step-by-step explanation:
t(150) = 400/570-150
=400/420
=20/21
=.95238

Jacob, non Hispanic white male. 30 years old.
Probability that Jacob lives to be 30 years old.
Since the given probabilities are probabilities of dying, I think we simply subtract it from 1 to get the probability of living. We will use the probability of non Hispanic white male.
Probability of living to be 30 y.o.

Answer: (x - 2) ^2 + (y - 6) ^2 = 25
Answer:
(x - 48)² + (y - 24)² = 64Step-by-step explanation:
From the graph we see that
The diameter of the circle is: d = 16 mmThen its radius is: r = 16 mm/ 2 = 8 mmThe center has x-coordinate: h = 40 + 8 = 48Y-coordinate: k = 32 - 8 = 24Use circle formula:
(x - h)² + (y - k)² = r²Substitute values to get required equation:
(x - 48)² + (y - 24)² = 8²(x - 48)² + (y - 24)² = 64Which symbol correctly compares the fractions below?
1/8 ? 1/2
Answer:
< "less than sign"
Step-by-step explanation:
1/8 is 0.125 in decimal form.
1/2 is 0.5 in decimal form.
Therefore, 1/2 is greater than 1/8 so you would use the less than symbol (<) for a final answer of 1/8<1/3.

PLLSSS HELP ME!! Which of the following functions accurately represents f??
Answer:
C. f(x) = x - 9 is the function that accurately represents f
Step-by-step explanation:
Plug in a value from the table to check which function is correct
1. Plug in x = 3 and check if you get -6.
A. f(3) = -4(3) + 12 = -12 + 12 = 0 -> 0 ≠ -6 so A is not the correct function
B. f(3) = 3(3) + 2 = 9 + 2 = 11 ≠ -6 so B is not the correct function
C. f(3) = 3 - 9 = -6 = -6 so C is the correct function
D. f(3) = -5(3) - 1 = -15 - 1 = -16 ≠ -6 so D is not the correct function

Identify CD. Please help ASAP
Answer: CD=7
Step-by-step explanation: By the definition of congruence, AB=CD.
Substitute the given expressions for AB and CD.
x+5=2x+3
Subtract x from both sides.
5=x+3
Subtract 3 from both sides.
2=x
Substitute x=2 back into the expression for CD and simplify.
CD=2(2)+3=7
Therefore, CD=7.

What is the constant?
What is the coefficient?
What is the variable?
What are the factors of 9x?
Answer:
the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27
Step-by-step explanation:
Answer:
The constant is 3
The coefficient is 12
The variables are both A and Y.
Disclaimer: I'm not sure about this next one, but I believe it's right.
9x factors are 3x, 1, and 9x.
If you wanted me to factor it, then it'd be something like 3x(3)
Step-by-step explanation:
A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.
A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.
The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.
The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.
9 times 1x is 9x, 9x times 1 is also 9x.
3 times 3x is 9x, and 3x times 3 is again, 9x.

If the triangle and the rectangle have the same area, what is the value of n if m=6?
Answer:
n=3
Step-by-step explanation:
Triangle area: height*length*(1/2)
Rectangle area: width*length
Let's say x is the length, then our equation would be:
mx(1/2)=nx
we also know m is 6, so
6x(1/2)=nx
now we can solve for n
6x(1/2)=nx
3x=nx
3=n
n=3
