Angle ABC measures 140°. Angle DBC bisects ∠ABC. Angle EBC bisects ∠DBC. What is the measure of ∠EBC?
Brrunno [24]

Answer:

\angle{EBC}=35\textdegree

An angle bisector divides the angle measure into two equal parts. In triangle ABC, B is the point at which the angle lies.

Step-by-step explanation:

Picture segment BD drawn from point B of tri.ABC where it connects to segment AC, creating point D. Now picture E drawn on the newly created segment DC where it connects to point B and down to point C. Here's a drawing to better show this:

It's bisecting the bisected angle ABC. So, 140/2 = 70, and 70/2 = 35.

To raise money, the Boy Scouts bought 190 kg of taffy for $723.90. They sold the tafty in 400 g bags
babunello [35]

They made profit of \$834.10 by selling 190 kg of taffy in 400 g bags at rate of \$3.28 each.

<u>Solution: </u>

Given that  

To raise money, the Boy Scouts bought 190 kg of taffy for \$723.90.

They sold the tafty in 400 g bags for \$3.28\text{ each }

Need to calculate the profit the made.

Cost price of 190 kg of taffy = \$723.90

As 1 kg = 1000 gram,

So 190 kg of taffy = 190\times 1000 = 190000\text{ grams of taffy }

So cost price of 190000 gram of taffy = \$723.90

Now let us calculate number of 400 grams bags which can be made from 190000 grams of taffy

Number of 400 grams bags = \frac{190000}{400}=475 \text { bags }

Amount generated from 1 bag of 400 gram taffy = 3.28

So amount generated from 475 bags of taffy = 475\times3.28 = \$1558

Selling price of 190000 grams of taffy = amount generated from 475 bags of taffy = \$1558

\text{ Profit }= \text{ selling price }-\text{ cost price }= 1558-723.90 = \$834.10

Hence they made profit of \$834.10 by selling 190 kg of taffy in 400 g bags at rate of \$3.28

An animal cage is holding 8 black cats and 11 white cats. All of them want to get out of the cage. The cage door is opened sligh
Deffense [45]

Answer:

A cage holds 6 black cats and 9 white cats, if two cats escape what is the probability of both cats being white?

Step-by-step explanation:

This involves two events, each with their own probability. Because both the first AND the second have to happen for this problem, you will MULTIPLY the wo individual probabilities.

Total cats = 15, White cats = 9

Probability first escaped cat is white = 9/15

One white cat has now escaped, so we now have Total cats = 14, White cats = 8

Probability second escaped cat is white = 8/14

Now MULTIPLY because this is an AND probability problem. (9/15)(8/14) = 72/210 = 12/35

Someone please do this and explain in detail of how you get x.
Afina-wow [57]

Answer:

x=8

AC=148

Step-by-step explanation:

Okay so if B is the midpoint of AC, that basically means that it's the halfway point. If B is exactly halfway between A and C, that means that the distance between A and B, and the distance between B and C is the same. In other words: AB=BC

Knowing that AB=BC, we can sub the values given by the question:

AB = BC

9x+2 = 5x+34

9x-5x = 34-2

4x = 32

x = 8

Now that we know the value of x, we can find AC, since AC=AB+BC

AC = AB + BC

= 9x+2 + 5x+34

= 14x+36

= 14(8)+36

=112+36

=148
