Ren and Isaac will eat the pizza in a 7 minutes

8 0

Answer:

1.71 min per pizza

Step-by-step explanation:

Ren's rate:

3 min per pizza (take inverse to get pizza per min)

= 1/3 pizza per min

Issac's rate:

4 min per pizza (take inverse to get pizza per min)

= 1/4 pizza per min

Combined rate = Ren's rate + Issac's rate

= 1/3 + 1/4

= 4/12 + 3/12

= 7/12 pizza per min   (take inverse to get min per pizza)

= 1 / (7/12) min per pizza

= 12/7 min per pizza

= 1.71 min per pizza

Help me with this math problem, I need someone to guide me through it I don’t understand what I’m supposed to do first
natita [175]

Answer:

see below

Step-by-step explanation:

The parent function is x^2 which is a parabola at vertex (0,0)

g(x) = ( x+3) ^2

y = f(x + C) C > 0 moves it left  

So the parabola is shifted to the left 3 units

h(x) = -( x+3) ^2

y = −f(x)  

Reflects it about x-axis

Means flip it about the x axis

Determine and state the coordinates of the center and length of the radius of a circle whose equation is
padilas [110]
First, rewrite the equation in standard form.
The center-radius form of the circle equation<span> is in the format:
(x – h)^</span>2<span> + (y – k)^</span>2<span> = r^</span>2
<span>with the center being at the </span>point<span> (h, k) and the radius being "r".
</span>
(x-3)^2 + (y+4)^2 = 81

From here, you can determine the center and radius. The center is at (3,-4) and the radius is 9.

In the triangle below, 8/15 represents which ratio?
Temka [501]
In trigonometry, the trigonometric ratios are used to determine the value of the trigonometric functions of the angles of a right triangle.

The trigonometric ratios is commonly called SOH-CAH-TOA, according to the formulas used to obtain then.

Given a right triangle with angles A, B and C and sides 17, 8 and 15.

Since, the denominator of the given ratio is 15, which is not the hypothenuse (the slant side), thus, the trigonometric function is neither sin nor cos but tan, thus we look for the angle which the side of length 15 is the adjacent side. The required angle is B.

Therefore, 8/15 represent tan B.
