Answer:
Since flipping a coin and rolling a 6-sided die are independent events ,thus the probability of getting head and an even number is just the product of the individual probability of events.
Let A be the event of getting a head ,and B be the event of getting an even number on die.
therefore, P(A and B)=P(A) P(B)=(1/2)*(3/6)=1/4=0.25
One letter weights 12 ounces.The mail carrier is allowed to carry 30 pounds.How many letters can he carry?
Answer:
The mail carrier can carry 40 letters.
Step-by-step explanation:
The first step is to put ounces into pounds.
1 lb = 16 oz This is the unit rate
0.75 lbs = 12 oz
Now put the 30 lbs into ounces
30 lbs = 480 oz
Divide 480 oz by 12 oz to find how many letters equal 480 oz.
480/12 = 40 letters
If this answer is correct, please make me Brainliest!

A pole 6m high has a shadow 10 m long when the shadow of a nearby building is 220 m long. How tall is the building?
Which ratio is equal to the ratio of the height of the building to its shadow?
By using the similar triangles principle, the height of the building is found to be 132 meters. We find this by setting up a proportion between the known ratios of the pole's height to its shadow and solving for the building's height.
Explanation:We can solve the problem using similar triangles. The ratio of the height of the pole to its shadow is the same as the ratio of the height of the building to its shadow. Since the height of the pole is 6m and its shadow is 10m, we have the ratio of the height to the shadow for the pole as 6/10 or 3/5.
This ratio will be equal to the ratio of the height of the building (which we'll call h) to the shadow of the building (220 m), so we can write the proportion as:
3/5 = h/220
Now we solve for h:
3/220 = h/5
h = (3/5) × 220
h = (3 × 44)
h = 132m
So the height of the building is 132m.
Adult tickets to a basketball game cost $5. Student tickets cost $1. A total of $3,228 was collected on the
sale of 1,340 tickets. How many of each type of ticket were sold?
Answer:
Okay, so 2 years later, here's your answer.
472 adult tickets and 868 student tickets were sold.
Step-by-step explanation:
Let x be the number of adult tickets sold.
Let y be the number of student tickets sold.
Your Equations:
x + y = 1340 tickets
5x + (1)y = $3228
Isolate the y variable:
y = 1340 - x
y = 3228 - 5x
Substitute:
1340 - x = 3228 - 5x
Solve:
1340 - x = 3228 - 5x
Add 5x on both sides
1340 + 4x = 3228
Subtract 1340 on both sides
4x = 1888
Divide 4 on both sides
x = 472
Plug in x into an equation:
472 + y = 1340
Subtract 472 on both sides
y = 868
472 adult tickets were sold
868 student tickets were sold.

Matthew bought a laptop for $34,000 in the year 2008. Its value depreciates by 4% per year. What is the
value of laptop in 2011?
The value of the laptop in 2011 will be $29920
Step-by-step explanation:
Cost of the laptop = $34000
Rate of decrease in value per year = 4%
Total time = 3 years
The Value decrease in 2011 = (34000 x 4 x 3) /100
= $4080
The value of the laptop in 2011 = 34000-4080
= $29920
The value of the laptop in 2011 will be $29920

Comment on units conversion
I find it convenient to work units conversion problems by writing a fraction that is equal to 1 and multiplying by that to change units. My fraction has the "to" units in the numerator, and the "from" units in the denominator. That way, the unwanted units cancel when the multiplication is carried out.
The fraction is equal to 1 because the measurement in the numerator is equal to the measurement in the denominator.
__
Some folks prefer proportions. If you do it that way, be sure "like" is matched with "like".
map inches/ground miles = 1/9.5 = x/24
route inches/scale inches = route miles/scale miles = x/1 = 24/9.5

Find the circumference and the area of a circle with radius 5 cm.
Write your answers in terms of n, and be sure to include the correct units in your answers.
The circumference of the circle is 10π cm, and the area is 25π cm².
The formulas for the circumference (C) and area (A) of a circle in terms of
the radius (r) are:
Circumference (C) = 2πr
Area (A) = πr²
Given that the radius (r) is 5 cm, we can substitute this value into the formulas:
Circumference (C) = 2π(5) = 10π cm
Area (A) = π(5)² = 25π cm²
So, the circumference of the circle is 10π cm, and the area is 25π cm².

Final answer:
To create a new model for the total sales of green tea and fruit juice, the sales equations for both products are added together and simplified, resulting in the model A = 3t² + 1093, representing combined sales in billions as a function of time in years.
Explanation:
To find a new model A for the total number of new green tea and fruit juice sales, we need to combine the models given for G (green tea sales) and J (fruit juice sales). The models provided had some errors, but they should be:
G = 674 + 3t – 2t² + 5t + 60
and
J = 314 – 3t + 5t² – 5t + 45
Combining these models to form A (total sales), we add G and J together:
A = G + J
= (674 + 3t – 2t² + 5t + 60) + (314 – 3t + 5t² – 5t + 45)
Now, we simplify the equation by combining like terms:
A = (674 + 314) + (3t – 3t) + (5t – 5t) – 2t² + 5t² + (60 + 45)
A = 988 + 0t + 0t + 3t² + 105
A = 988 + 3t² + 105
A = 3t² + 1093
Therefore, the new model A for the total sales is A = 3t² + 1093. This model represents the combined sales of green tea and fruit juice in billions of dollars during the 20-year period as a function of time t in years.

Answer:
Cliff is 45 m tall.
Step-by-step explanation:
Given:
Height of Sarah = 1.8 m
Angle of elevation = 60°
Angle of elevation 50 m back = 30°
As shown in the figure we have two right angled triangles SPQ and SPR.
Let the height of the cliff be [tex]h[/tex] meters and [tex]h= h_1+h_s[/tex].
Using trigonometric ratios:
tan (Ф) = opposite/adjacent
In ΔSPQ. In ΔSPR.
⇒ [tex]tan(60) = \frac{h_1}{x}[/tex] ...equation (i) ⇒ [tex]tan (30)=\frac{h_1}{x+50}[/tex] ...equation (ii)
Dividing equation (i) and (ii)
⇒ [tex]\frac{tan(60)}{tan(30)} = \frac{h_1}{x} \times \frac{x+50}{h_1}[/tex]
⇒ [tex]3 = \frac{x+50}{x}[/tex]

⇒ [tex]3x-x=50[/tex]
⇒ [tex]2x=50[/tex]
⇒ [tex]x=\frac{50}{2}[/tex]
⇒ [tex]x=25[/tex] meters
To find [tex]h_1[/tex] plugging [tex]x=25[/tex] in equation (i)
⇒ [tex]h_1=x\times tan(60)[/tex]
⇒ [tex]h_1=25\times 1.73[/tex]

The height of the cliff from ground :
⇒ [tex]h= h_1+h_s[/tex]

The cliff is 45 m tall to the nearest meter.
Angles 1 and 2 are complementary. If ∠1 measures 56°, what is the measure of ∠2?
Final answer:
To find the measure of angle 2, which is complementary to angle 1 with a measure of 56°, subtract 56° from 90°, resulting in angle 2 measuring 34°.
Explanation:
If angles 1 and 2 are complementary, it means that the sum of their measures is 90 degrees. Since the measure of ∠1 is given as 56°, we can find the measure of ∠2 by subtracting the measure of ∠1 from 90 degrees:
Measure of ∠2 = 90° - Measure of ∠1
Measure of ∠2 = 90° - 56°
Measure of ∠2 = 34°
Therefore, the measure of ∠2 is 34 degrees.

This set of ordered pairs is a function (22, 4), (21, 1), (0, 0), (1, 1), and (2, 4).
Please explain like you were teaching how you can know this is a function.
Answer:
Step-by-step explanation:
You know these ordered pairs are considered a function, because the x intercepts do not repeat themselves. In other words, each input numbers are different. If these ordered pairs were not a function, the x intercept would be repeating. For example, 22 is already a x intercept, (22,4), if 22 was put in as another x intercept like,(22,1) these ordered pairs would not be a function.
