T = 12 min,  T o = 80° C, T s = 50 °C,  T ( 12 ) = 60° C
60 = 50 + ( 80 - 50 ) · e^(-12k)
10 = 30 · e^(-12k)
e^(-12k) = 0.3333...
ln ( 0.333.. ) = - 12 k
- 12 k = - 1.1
k = ( - 1.1 ) : ( - 12 ) = 0.0916
Answer: D ) 0.0916

The measure of an inscribed circle of an angle is the measure of the intercepted arc
Andre45 [30]

Answer:

(the statement does not appear to be true)

Step-by-step explanation:

I don't think the statement is true, but you CAN compute the intercepted arc from the angle.

Note that BFDG is a convex quadrilateral, so its angles sum to 360. Since we know the inscribed circle touches the angle tangentially, angles BFD and BGD are both right angles, with a measure of 90 degrees.

Therefore, adding the angles together, we have:

alpha + 90 + 90 + <FDG = 360

Therefore, <FDG, the inscribed angle, is 180-alpha (ie, supplementary to alpha)

Used the diagram below to name the relationship of the given angles <br> HELPP MEEE!!!!!!!
Lady_Fox [76]

Answer:

a. vertical

b. corresponding

c. same-side interior angles

d. alternate exterior

e.alternate interior

f. same-side exterior

g. vertical angles

h. corresponding angles  

Step-by-step explanation:  

Definitions:  Alternate interior angles: two nonadjacent interior angles on opposite sides of the transversal.  

Same-side interior angles: two interior angles on the same side of the transversal.  

Corresponding angles: two angles in corresponding positions relative to the two lines  

a. Angle 1 and Angle 4:  These angles are vertical angles.  

b. Angle 2 & Angle 6:  These angles are corresponding angles.  

c. Angle 3 and Angle 5:  Same-side interior angles

d. Angle 1 & Angle 8:  Alternate exterior

e. Angle 4 and Angle 5:  Alternate interior angles

f. <2 & <8

Same-side exterior angles

g. <6 & <7    vertical angles

h. <3 & <7

Corresponding angles

PLS PLS PLS BE QUICK SPAM will be reported
Paraphin [41]

Solving a linear equation, we conclude that she made 5 batches of cookies.

<h3>How many batches of cookies has she made?</h3>

We know that Alexis bought a bag that contains 8 cups of m&m's. First, she uses two-thirds of a cup to make each batch, so for x batches, she needs:

B(x) = (3/5)*x

That linear equation tells us how many cups are used to make x batches.

We know that at the end, she has 5 cups, and she started with 8 cups, so she used:

8 cups -5 cups = 3 cups.

Now we need to solve the linear equation:

B(x) = 3 =  (3/5)*x

Solving the linear equation for x we get:

3 = (3/5)*x

3*(5/3) = x

5 = x

This means that she made 5 batches of cookies.
