Step-by-step explanation:

in both questions it says to simplify the boys ratio so if you have to simplify they boys then you'll have to find the GCF (Greatest common factor) of both of the number 10 and 12. And the GCF of 10 is 5, and the GCF of 12 is 6 so its 5:6

Answer:

Juan has 32 dimes, 16 nickels and 8 quarters in his coin bank.

Step-by-step explanation:

Since in Juan's coin bank there are nickels (n), dimes (d), and quarters (q), and the number of quarters is one-quarter the number of dimes, and the number of nickels is twice the number of quarters, While the total value of the coins is $ 6.00, to find the number of each type of coin the following calculations must be performed:

Q = 1/4 D

N = 2Q = 1/2 D

D = D

20D + 10N + 5Q = X

20 x 0.10 + 10 x 0.05 + 5 x 0.25 = X

2 + 0.50 + 1.25 = X

3.75 = X

24D + 12N + 6Q = X

24 x 0.10 + 12 x 0.05 + 6 x 0.25 = X

2.40 + 0.60 + 1.50 = X

4.50 = X

32D + 16N + 8Q = X

32 x 0.10 + 16 x 0.05 + 8 x 0.25 = X

3.20 + 0.80 + 2 = X

6 = X

So, Juan has 32 dimes, 16 nickels and 8 quarters in his coin bank.

Answer: The answer to what is the measure of angle x is 48°.

Step-by-step explanation: It’s because this angle is complementary Two Angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Example: 5° and 85° are complementary angles.

48°+42°=90° and this is a right scalene triangle.

Answer:

8

Step-by-step explanation:

The measure of an inscribed angle is half the measure of the intercepted arc.

m<T = (1/2)m(arc)SU

Set the polynomial equal to

y

to find the properties of the parabola.

y = -3(x+4)^2 - 8

Use the vertex form, y = a (x-h)^2 + k, to determine values of a,h and k

a = -2

h = -4

k = -8

Find the vertex (h,k)

(-4, -8)

As per the vertex form of a quadratic equation, the vertex of the given quadratic equation is (4, 8).

"A quadratic equation is an algebraic equation of the second degree in x. The quadratic equation in its standard form is ax² + bx + c = 0, where 'a' and 'b' are the coefficients, 'x' is the variable, and 'c' is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x² is a non-zero term(a ≠ 0)."

"The vertex form of a quadratic equation is:

y = a(x - h)² + k

Here, a, h, and k are real numbers, where a ≠ 0. x and y are variables.

Here, (h, k) is the vertex and (x, y) represents a point on the graph of the given equation."

Here, the given quadratic equation is:

y = f(x) = -2(x - 4)² + 8

By comparing it with the vertex form of a quadratic equation, we get:

h = 4, y = 8.

Therefore, the vertex(h, k) of the given quadratic equation is (4, 8).

3[tex]\sqrt{2}[/tex] divided by 3 equals [tex]\sqrt{2}[/tex], which is irrational

Answer:

Vertical intercepts: (-2,pi/2) and (-10,pi/2)

Horizontal intercepts: (4,0) and (-4,0)

Step-by-step explanation:

I took the test and got it right.

The required horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).

In the equation intercept is the value of the linear function where either of the variables is zero.

To find the horizontal intercept(s) of the limacon, we need to set r equal to zero and solve for theta.

r = 4 - 6sin(Ф)

0 = 4 - 6sin(Ф)

6sin(Ф) = 4

sin(Ф) = 4/6

sin(Ф) = 2/3

We can use an inverse sine function to find the value of theta:

Ф= sin^-1(2/3)

Ф≈ 41.81° or 138.19°

These are the values of theta where the limacon crosses the x-axis (horizontal intercepts).

To find the vertical intercept(s), we need to set theta equal to zero or pi and solve for r.

When Ф= 0:

r = 4 - 6sin(0)

r = 4

So the limacon intercepts the y-axis at (0, 4).

When Ф= pi:

r = 4 - 6sin(pi)

r = 10

So the limacon intercepts the y-axis at (0, -10).

Therefore, the horizontal intercepts are at approximately (41.81°, 0) and (138.19°, 0), and the vertical intercepts are at (0, 4) and (0, -10).
