Answer:
B. 4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
4/7 * 1/3 = 4/21

Rob is on vacation in Paris, France. When Rob visited the Eiffel Tower today, he climbed 1,000 stairs in 25 minutes. Tomorrow, Rob will climb 280 stairs at Montmartre. If he climbs at the same rate, how many minutes will it take Rob to climb the stairs tomorrow?
Answer:
7 minutes
Step-by-step explanation:
The computation of the number of minutes that climbs the stairs tomorrow is shown below:
Given that
He claimed 1000 stairs in 25 minutes
So for 280 stairs, he would take
= 280 × 25 minutes ÷ 1000 minutes
= 7000 ÷ 1000
= 7 minutes
hence, 7 minutes would be taken
The same is to be considered
Answer:
7 minutes

Answer:
= 1/26
Step-by-step explanation:
Use Division Distributive Property:
(x/y)^a = x^a/y^a
(^, That means to the power of exponents.)
Then you Simplify 6^3 to 216
Then you will get 1 over 216.
Make sure answer is correct and please explain answer no random websites, they will get reported
Answer:
-9 is the answer
Step-by-step explanation:
So we know that the temperature was 2 degrees Fahrenheit in the morning. It dropped by 11 degrees, meaning -11 degrees.
2 + (-11) = ?

Two trains are 1.5 miles apart, train a is traveling at 3/4 the speed of train b if they meet in 4 minutes how fast is each train going
Answer:
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.
Step-by-step explanation:
Let suppose that train A begins in position [tex]x = 0\,mi[/tex] and the train B in position [tex]x = 1.5\,mi[/tex], if [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and both trains move at constant speed, then we have the following kinematic equations:
Train A
[tex]x_{A} = x_{A,o}+v_{A}\cdot t[/tex] (1)
Train B
[tex]x_{B} = x_{B,o}-v_{B}\cdot t[/tex] (2)
If both trains meet each other, then [tex]x_{A} = x_{B}[/tex]. If we know that [tex]x_{A,o} = 0\,mi[/tex], [tex]x_{B,o} = 1.5\,mi[/tex], [tex]v_{B} = \frac{3}{4}\cdot v_{A}[/tex] and [tex]t = \frac{1}{15}\,h[/tex], then we have the following expression:
[tex]x_{A,o}+v_{A}\cdot t = x_{B,o}-v_{B}\cdot t[/tex]
[tex]x_{A,o} + v_{A}\cdot t = x_{B,o} - \frac{3}{4}\cdot v_{A}\cdot t[/tex]
[tex]\frac{7}{4}\cdot v_{A}\cdot t = x_{B,o}-x_{A,o}[/tex]
[tex]v_{A} = \frac{4\cdot (x_{B,o}-x_{A,o})}{7\cdot t}[/tex]
[tex]v_{A} = 12.857\,\frac{mi}{h}[/tex]
Then, the speed of the train B is:
[tex]v_{B} = 9.643\,\frac{mi}{h}[/tex]
Train A is travelling at a speed of 12.857 miles per hour and train B at a speed of 9.643 miles per hour.
What happens to the value of the expression \dfrac{10}{d} d 10 start fraction, 10, divided by, d, end fraction as ddd increases from a small positive number to a large positive number?
Answer:
The quotient decreases
Step-by-step explanation:
Give the expression :
10 / d
What happens to the expression as d increases. from small positive to large positive ;
d in the expression is the denominator ;the value obtained by dividing the numerator by the denominator is the quotient.
Since the value of the numerator is constant ;
As the value of d increases, the quotient obtained becomes smaller `
For instance,
Let
d = 2;
10 /2 = 5
d = 3
10 / 3 = 3.333
d = 4
10 / 4 = 2.5

а. .
y = -x-4
C.
y=x+4
by=-x+4
d. y = x-4
Answer:
y = -x + 4
Step-by-step explanation:
Mathematically, the equation of a straight line is;
y = mx + b
where m is the slope and b is the y-intercept
from the plot, the y intercept is 4
So we have;
y = mx + 4
To get the value of m, we substitute the coordinates of any point and solve for m
we select the point; (4,0)
so;
0 = m(4) + 4
4m = 0-4
4m = -4
m = -1
so the equation of the line is;
y = -x + 4

Answer:
Ryan: 25 + 10h Alex: 20 + 11h
Mr. Smith should choose Alex - see below for reasoning
Step-by-step explanation:
The set-up fee does not change. It has no variable because it's already chosen. However, $/hour has a variable because the more hours a photo session takes, the more this number will increase when multiplied. Mr. Smith provides a good example of this. In his situation, h = 2 because his photo session will take two hours. If he hired Ryan, it would be $25 in set-up fees and then ten dollars per hour (h): [tex]25+10(2)[/tex] which totals out to $45. If he hired Alex, he would pay $20 for set-up fees and eleven dollars an hour (h): [tex]20+11(2)[/tex] which totals out to $42. So, Mr. Smith can save a few bucks if he hires Alex.
However, if someone expected hours and hours of photos - say, a fourteen-hour long photo session - then Ryan would be a better choice. His price would be [tex]25+10(14)[/tex] which totals to $165. Alex's price would be [tex]20+11(14)[/tex] which totals to $174. But I doubt anyone is going to want a fourteen-hour photo shoot, and I don't think Ryan nor Alex would want to do that either...

in a class with 28 students, 18 learn English and 13 learn French. Some students learn both languages. What is the number of students learning both languages?
a) 2
b) 3
c) 4
d) 5
Answer:
3
Step-by-step explanation:
18 + 13 is 31.
31 is more than 28, and for the people who learn both languages(x), we can do 31-28 = x. 31-28 is 3, so the answer is B, or 3.
A circle's circumference is approximately 44 cm. Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.
Answer:
See solutions below
Step-by-step explanation:
Complete question
A circle's circumference is approximately 44 cm.
Complete each statement using one of these values: 7, 11, 14, 22, 88, 138, 154, 196, 380, 616.
The circle's diameter is approximately cm.
The circle's radius is approximately cm.
The circle's area is approximately cm2.
Circumference of the circle =2πr
r is the radius of the circle
Circumference of the circle = 2(3.14)r
44 = 2(3.14)r
22 = 3.14r
r = 22/3.14
r = 7.0cm
The circle's radius is approximately 7cm.
Since diameter = 2r
diameter = 2 * 76
diameter = 14cm
The circle's diameter is approximately 14cm.
Area of the circle = πr²
Area of the circle = 3.14(7)²
Area of the circle = 3.14(49)
Area of the circle = 153.86sq.cm
The circle's area is approximately 154cm^2.

y1 = 6
y2 = - 1
Solution
d = sqrt( ( -3 - -5)^2 + (-1 - 6)^2 )
d = sqrt( ( -3 + 5)^2 + (-7)^2 )
d = sqrt( 2^2 + 49)
d = sqrt(4 + 49)
