Point C is on line segment \overline{BD}
BD . Given CD=2CD=2 and BD=17,BD=17, determine the length \overline{BC}.
BC .
15
Step-by-step explanation:The segment addition postulate states that if AC is a line with point B, then AB + CD must equal AC.
Setting Up the Equation
Using the postulate above we can set up an equation that is set equal to BD.
BC + CD = BDNow, rewrite this using the information we are given in the question.
BC + 2 = 17Solving For BC
Now, we can solve this equation using the properties of equality.
BC + 2 = 17To solve you need to isolate BC. Do this by subtracting 2 from both sides.
BC = 15This gives us the answer, 15.
39. Find the probability of selecting a multiple of 2 or a
multiple of 7 from the integers 1-20.
The probability of selecting a multiple of 2 or a multiple of 7 is 11/20 or 0.55 or √0.3025.
What is probability?It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Total number of outcome = 20
Total number of favourable outcome (multiple of 2 or a multiple of 7):
E = {2, 4, 6, 7, 8, 10, 12, 14, 16, 18, 20}
n(E) = 11
The probability = 11/20 = 0.55 or
= √0.3025
Thus, the probability of selecting a multiple of 2 or a multiple of 7 is 11/20 or 0.55 or √0.3025.

Directions: Using the digits 0-9, no more than once each, fill in the boxes to make the statement true:
The equation [tex]\frac{5-3-2}{1+4+6+7+8+9}[/tex] = 0 is true
What is fraction?
In arithmetic, a number expressed as a quotient, in which a numerator is divided by a denominator.
Using digits 0 to 9, no more than once each.
we want to place them in such a way that the division will be zero.
As we know that a quotient is equal to zero iff the numerator is equal to zero and the denominator other than zero.
So if we put some numbers on the numerator in such a way by adding them gives 0.
So, 5 - 3 - 2 = 0

Coach Jamison wants to celebrate the final win of the school’s softball season with a trio to the local fast food place. The team buys 26 delicious burritos and 27 orders of savory chips for $86.90. A few of the players are still hungry so the coach buys 14 more burritos and 9 more orders of chips for $40.70. If you don’t include tax, what is the price of a burrito and the price of an order of chips?
The price of Burritos is $ 2.2 and the price of savory chips is $1.1
What is system of equations ?
A system of equations is a set or collection of equations that you deal with all together at once.
Linear equations (ones that graph as straight lines) are simpler than non-linear equations, and the simplest linear system is one with two equations and two variables.
The price of 26 delicious burritos and 27 orders of savory chips for $86.90
4 more burritos and 9 more orders of chips for $40.70
Let us consider the price of Burritos is x
and the price of savory chips is y
from the first statement we can form the equation
26*x +27*y = 86.9
and from the second statement we can form the equation
14*x + 9*y= 40.70
To determine the price of each we have to solve these system of equations.
On solving using elimination method
16x = 35.2
x = $2.2
and y = $1.1
Therefore the price of Burritos is $ 2.2 and the price of savory chips is $1.1.

(URGENT) Maurice and Rhonda a are traveling in the same direction along the same road. Maurice is traveling at 55 mph and is exactly 15 miles ahead of Rhonda, who is traveling at 65 mph. How many hours will it take Rhonda to catch Maurice?
Answer:
Step-by-step explanation:
Givens
Maurice
55 miles an hour
15 miles ahead of Rhonda
d1
Rhonda
65 miles per hour
d2
The distance has to be the same for both in order to meet.
Formula
d1 = d2
d = r * t where r is the speed.
65*t = 55t + 15 Subtract 55t from both sides
Solution
65t - 55t = 55t - 55t + 15 Combine
10t = 15 Divide both sides by 10
10t/10 = 15t/10
t = 1.5 hours

The person's body temperature will approach 98.6ºF as time lapses, The horizontal asymptote of y = 0 means that the person’s temperature will approach 98.6ºF as time elapses.
What is horizontal asymptote?A horizontal asymptote is known to be that line that is horizontal in nature and it is one that is not an aspect of a graph that has a function but t act as a guides for its x-values.
Note that Horizontal asymptote occurs to T(f) only when t is said to be very large (as it approaches infinity) and thus, it connote that the person's body temperature will be going towards 0ºF above 98.6ºF as t moves to infinity.

What is a name for the marked angle?
Answer: [tex]\angle BAD[/tex]
Reason:
The arc goes from ray AB to ray AD. The two rays join at angle A which is the vertex point. When naming an angle, always use the vertex point in the middle. The order of the other two letters does not matter.
We could name this angle as [tex]\angle BAD[/tex] or [tex]\angle DAB[/tex] to mean the same exact thing. All that matters is that "A" is in the middle.
Ignore point C, and ignore ray AC entirely.
Answer:
(b) ∠BAD
Step-by-step explanation:
An angle can be named by the names of three points. The first point is on one of the rays that form the angle; the second point is the vertex; the third point is on the other ray.
Apparently the "marked" angle is identified by the arc extending from ray AB to ray AD. Point A is the vertex of the angle, so one possible name for it is ...
∠BAD

Thomas found a box that had a volume of 150 in3. He measured the height of the box to be 2 inches and the length was 10 inches more than the width. What is the width of the box?
The width of the rectangular box with volume of 150 cubic inches is: 5 inches.
What is the Volume of a Box?Volume of a box = (length)(width)(height).
Given the following:
Volume of the box = 150 in.³Height = 2 in.Width = w in.Length = w + 10 in.150 = (w + 10)(w)(2)
2w² + 20w - 150 = 0
