△ABC△ABC has interior angles with measures 130°, x°, and 15°, and △DEF△DEF has interior angles with measures 35°, 15°, and y°. U

sing the given information, which statement is true? The triangles are not similar because x≠yx≠y . The triangles are similar because y=130y=130 and there are three pairs of congruent angles. The triangles are not similar because x≠15x≠15 . The triangles are similar because they each have an interior angle with measure 15°.

How many cubes with edge lengths of 1/4 in. will it take to fill the prism?
Ulleksa [173]

Answer:

1560

Step-by-step explanation:

First (2 1/2)/(1/4) = (5/2)(4) = 20/2 = 10

Next, 3/(1/4) = 3(4) = 12

Lastly, (3 1/4)/(1/4) = (13/4) x 4 = 52/4 = 13

This means we need 10 rows of 12, 13 high. 10(12)(13) = 1560 cubes.

Another way is to multiply 2 1/2 x 3 x 3 1/4 = 5/2 x 3 x 13/4 = 195/8

A 1/4 inch cube is 1/4 x 1/4 x 1/4 for a volume of 1/64

(195/8)/(1/64) = (195/8)(64) = 1560 cubes.

Which ordered pair is the solution to the system of equations? {x+3y=-12, y= 1/3x-6?
Julli [10]

For this, I'll be using the substitution method. Since y = 1/3x - 6, replace the y variable in the first equation with 1/3x - 6 and solve for x:

x+3(\frac{1}{3}x-6)=-12\\ x+x-18=-12\\ 2x-18=-12\\ 2x=6\\ x=3

Now that we have the value of x, plug it into either equation to solve for y:

3+3y=-12\\ 3y=-15\\ y=-5\\ \\ y=\frac{1}{3}*3-6\\ y=1-6\\ y=-5

<h3><u>In short, the solution to this equation is (3,-5).</u></h3>

Identify whether the function f(x)=3x5 is a monomial function, power function, both, or neither.
marshall27 [118]

Answer:

f(x)=3x5 is both  monomial function, power function

Step-by-step explanation:

Monomial function is one which has only one term that is non-zero term.

example

b is a monomial with one variable

5xy^2 is a monomial with two variable

10x^10 is a monomial with one variable.

_______________________________________

power function is one which consist of a coefficient, a variable and that variable is raised to some non-zero power.

example

2x^6

area of circle = \pi r^2

_____________________________________

given function

f(x)=3x5

1. it has only one non zero term thus qualifies to be called monomial

2. It has a coefficient 5, a variable x and that x is raised to some non-zero power 5. Thus, it is a power function as well.
