Answer:
x = 12
Step-by-step explanation:
The angles are equal as they are alternate exterior angles.
Solving :
⇒ 4x + 16 = 7x - 20
⇒ 7x - 4x = 16 + 20
⇒ 3x = 36
⇒ x = 12

A baseball coach draws names to decide who will be the first player at bat There are 5 girls and 10 boys on the team Describe and explain the probability of each outcome
a. The first batter is a girl
b. The first batter is a boy
Using the probability concept, it is found that:
a) P(girl) = 1/3, which means that 1/3 = 33% of the time, the first batter will be a girl.
b) P(boy) = 2/3, which means that 2/3 = 67% of the time, the first batter will be a boy.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
In this problem, in a total of 15 people, 5 are girls and 10 are boys, hence:
P(girl) = 5/15 = 1/3.P(boy) = 10/15 = 2/3.More can be learned about probabilities at https://brainly.com/question/14398287

find the missing angles
Answer:
the missing angles are 47,° 77,° 56°
Step-by-step explanation:
(133)+(x+13)= 180° (angles on a straight line)
133+x+13= 180°
146+x= 180°
X= 180-146
X= 34°
FOR ANGLE A
2X+9= 2(34)+9= 68+9= 77°
FOR ANGLE C
X+13= 34+13= 47°
FOR ANGLE B
47+77+Y= 180 (SUM OF ANGLES IN A TRIANGLE)
124+Y= 180
Y= 180-124= 56°
Y= 56°

Step-by-step explanation:
when you are on that level of math that you get this type of question - this is totally easy.
we get the extreme point(s) of a function by finding the zeros of the first derivative of the function.
f'(x) = 4x - 8
so,
0 = 4x - 8
8 = 4x
x = 2
to determine whether it is a minimum or a maximum, we have 2 choices :
the quick way for a quadratic (parabola) equation by looking at the factor of x² : is it >0, then the parabola opens up upwards, and the extreme point is therefore a minimum. if it is <0, then it opens downward, and the extreme point is a maximum.
in our case : 2 is larger than 0, therefore minimum.
or the formal way for any type of function : create the second derivative and see, if it is >0 (minimum) or <0 (maximum) for the extreme x.
in our case
f''(x) = 4
this is larger than 0 for all x, so the extreme point is a minimum.

Assuming the pizzeria is located at the
origin, write an equation of the circle in
which the pizzeria will deliver in standard
form where x and y represent the distance
from the pizzeria in miles.
The equation of the circle represented by the pizza is x^2 + y^2 = 4
How to determine the equation of the circle?The given parameters are:
Radius, r = 2
Center, (a,b)= (0,0) i.e. origin
The equation of the circle is calculated as:
(x - a)^2 + (y - b)^2 = r^2
This gives
(x - 0)^2 + (y - 0)^2 = 2^2
Evaluate the exponents
x^2 + y^2 = 4
Hence, the equation of the circle is x^2 + y^2 = 4

Elias was given a lock for his school locker. The lock contains numbers between
O and 59 (60 different numbers). If 3 numbers are used to unlock the lock, and
the numbers can't repeat, how many codes can his lock have?
Answer:
34,220
Step-by-step explanation:
Because order doesn't matter, but the numbers can't be repeated, we need to find the number of combinations where 3 individual numbers can be chosen out of 60 possible numbers using the binomial coefficient:
[tex]\binom{n}{k}=\frac{n!}{k!(n-k)!}\\ \\\binom{60}{3}=\frac{60!}{3!(60-3)!}\\\\\binom{60}{3}=\frac{60!}{3!(57)!}\\\\\binom{60}{3}=\frac{60*59*58}{3*2*1}\\ \\\binom{60}{3}=34220[/tex]
Thus, Elias can make 34,220 unique 3-number codes given 60 different numbers.
A motorboat travels 82 miles in 2 hours going upstream. It travels 106 miles going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current
let's recall d = rt, or namely distance = rate * time.
b = speed of the boat in still water
c = speed of the current
when going Upstream, the boat is not really going "b" fast, is really going slower, is going "b - c", because the current is subtracting speed from it, likewise, when going Downstream the boat is not going "b" fast, is really going faster, is going "b + c", because the current is adding its speed to it.

Keyshawn's collection after w weeks?
A. w = 25b + 100
B. w = 100b+25
C. b = 25w + 100
D. b = 100w + 25
Answer:
C. b = 25w + 100
Step-by-step explanation:
Keyshawn starts off with 100 baseball cards. Each week he buys 25 more baseball cards. Given this we want to find an equation that would represent the number of baseball cards (represented by "b") he would have after a number of weeks (represented by "w")
We know that keyshawn buys 25 baseball cards weekly so the number of baseball cards purchased after w weeks can be represented by 25w.
We also know that he started of with 100 baseball cards so the total amount of baseball cards keyshawn has (b) can be represented by the expression b = 25w + 100

An online store typically ships packages at a rate of 15 orders every 5 hours. At this rate, how many hours will it take to ship 156 orders?
Answer:
52 hours
Step-by-step explanation:
figure it out genius
An online store ships 15 orders every 5 hours. It will take approximately 52 hours to ship 156 orders at this rate.
Use the concept of ratio defined as:
A ratio indicates how many times one number contains another number. The ratio of two numbers is written as x : y, which is equivalent to x/y.
Where x and y are individual amounts of two quantities.
And, the Total quantity is given after combining as x + y.
Given that,
Online store ships packages at a rate of 15 orders every 5 hours.
We need to determine how many hours it will take to ship 156 orders.
The rate can be expressed as 15 orders per 5 hours or 15/5.
To figure this out,
Set up a proportion.
If the online store ships 15 orders every 5 hours,
Then the rate is 15 orders per 5 hours, or 15/5.
Now, let's set up the proportion:
15/5 = 156/x
To solve for x, cross multiply:
15x = 5(156)
Now, divide both sides of the equation by 15 to isolate x:
x =780/15
Calculating that out, x is equal to 52.
Hence, it will take approximately 52 hours to ship 156 orders at the given rate.
