Answer: The mean is 47.
There are 5 numbers.
To find the mean of them we add them and divide the sum by 5.

Answer:
65 square inches.
Step-by-step explanation:
To solve for this irregular figure, you must break it into separate rectangles.
Firstly, we can solve for the area of the top rectangle by:
6×4= 24 sq in.
For the next rectangle, we can do:
4×8= 32 sq in.
Finally, the remaining square can be solved by:
3×3= 9 sq in.
To get the ENTIRE area, you will need to add these areas up which gets you:
24+ 32+ 9= 65 sq in.

Answer:
26 square feet (no floor)38 square feet (with floor)Step-by-step explanation:
The triangular end of the tent has a base of 3 ft and a height of 2 ft. Its area can be found using the formula for the area of a triangle:
A = (1/2)bh
A = (1/2)(3 ft)(2 ft) = 3 ft^2
__
The rectangular side of the tent has a length of 4 ft and a width of 2.5 ft. Its area can be found using the formula for the area of a rectangle:
A = lw
A = (4 ft)(2.5 ft) = 10 ft^2
___
If we assume the tentmaker makes the two sides not shown exactly the same as these, then the total above-ground material will be ...
2(3 ft^2 +10 ft^2) = 26 ft^2
If there is on-ground material (a floor), that rectangle adds (3 ft)(4 ft) = 12 ft^2 to the total.
The area of the tent above-ground is 26 square feet. With a floor, it is 38 square feet.

Answer:
sin A = 40/41
tan A = 40/9
cos A = 9/41
Step-by-step explanation:
sin theta = opp/ hyp
tan theta = opp/ adj
cos theta = adj/ hyp
We want to find the measures for angle A
sin A = 40/41
tan A = 40/9
cos A = 9/41
Answer:
SinA = opposite/hypotenuse
SinA = 40/41
SinA = 0.976
(0.9756097561)
TanA = opposite/adjacent
TanA = 40/9
TanA = 4.444
(4.44444444)
CosA = adjacent/hypotenuse
CosA = 9/41
CosA = 0.220

It is 85 miles from central city to smithville and 125 miles from smithville to jonesburg. How many gallons of gas will it take to drive from central city to smithville to jonesburg in a car which gets 30 miles per gallon?
It will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.
To calculate the total amount of gas needed to drive from Central City to Smithville to Jonesburg, we need to add up the distances for each leg of the trip and then divide by the car's mileage per gallon.
Central City to Smithville: 85 miles
Smithville to Jonesburg: 125 miles
Total distance: 85 + 125 = 210 miles
Given the car gets 30 miles per gallon, divide total distance by mileage per gallon:
Total gallons of gas needed = 210 miles ÷ 30 MPG = 7 gallons
Therefore, it will take 7 gallons of gas to drive from Central City to Smithville to Jonesburg in a car that gets 30 miles per gallon.

What’s the value of x?
Answer:
150 degrees
Step-by-step explanation:
Let's call the angle in the triangle next to the 78 A, the one next to the 132 B, and the one next to the x C. You know that the measure of angle A is 180-78=102 because they are linear pairs. Similarly, the measure of angle B is 180-132=48 degrees. Because all of the angles in a triangle must add up to 180 degrees, C must be 180-102-48=30 degrees. Finally, since x and C are linear pairs, x's angle measure must be 180-30=150 degrees. Hope this helps!
x squared plus 8 squared equals 9
What is X?
Answer:
x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]
Step-by-step explanation:
x^2 + 8^2 = 9
Simplify the 8^2
x^2 + 64 = 9
Subtract 64 from both sides
x^2 = -55
Take the square root from both sides
x = +/- [tex]\sqrt{-55}[/tex]
Simplify
x = [tex]i\sqrt{55} , -i\sqrt{55}[/tex]

Which triangle is a translation of triangle X?
On a coordinate plane, triangle X is shifted 3 units down and 4 units to the left to form triangle B.
triangle A
triangle B
triangle C
triangle D
Final answer:
Triangle B is the translation of triangle X as it is moved 3 units down and 4 units to the left.
Explanation:
The question involves finding a triangle that is a translation of another triangle on a coordinate plane. A translation in geometric terms means moving a shape in the plane without rotating or resizing it.
According to the given information, triangle X is translated 3 units down and 4 units to the left to form triangle B.
Based on this information, triangle B is the translated figure of triangle X, and thus it is the correct answer.

What is the largest number that he can make?
9754
What is the smallest even number that he can make?
Answer: smallest 5794
Step-by-step explanation:
Answer:
5794
Step-by-step explanation:
5794 is the answer because...
Step one If we want to find the smallest even number we have to find out what the smallest number is first. So A trick I have learned is when you have the biggest number the smallest number is just the biggest number backwards. so if it was 9754 the smallest number is 4579.Step two since this is an odd number we have to make the last number of the smallest number even. To do so we have to take the smallest even number which is 4 and out it at the end. We also have to keep the number at it's smallest.Step 3 is to rewrite the Answer. Now we have four at the end our new number is 5794Hope this helped :)What is the volume of the cylinder below?

A line is parallel to y = -2x + 1 and
intersects the point (4,1). What is the
equation of this parallel line?
Answer:
For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:
[tex] y =-2 x+b[/tex]
Now we can find the intercept b with the condition given x= 4 , y=1 and we got:
[tex] 1 = -2*4 +b[/tex]
And solving for b we got:
[tex] b = 1+8 = 9[/tex]
And our equation would be:
[tex] y = -2x +9[/tex]
Step-by-step explanation:
For this case we need to find an equation for a line who is parallel to y = -2x + 1 and intersects the point (4,1)
The general equation for a line is given by:
[tex] y = mx +b[/tex]
For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:
[tex] y =-2 x+b[/tex]
Now we can find the intercept b with the condition given x= 4 , y=1 and we got:
[tex] 1 = -2*4 +b[/tex]
And solving for b we got:
[tex] b = 1+8 = 9[/tex]
And our equation would be:
[tex] y = -2x +9[/tex]
Can someone help me with this one
Answer:
A
Step-by-step explanation:
Equate the congruent sides of the side, that is
2x + 2 = x + 6 ( subtract x from both sides )
x + 2 = 6 ( subtract 2 from both sides )
x = 4
and
y - 5 = x + 5 = 4 + 5 = 9 ( add 5 to both sides )
y = 14
Thus
top pair = x + 5 = 4 + 5 = 9 and lower pair = x + 6 = 4 + 6 = 10
A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the show
The cost of each ticket is $4.
How to find the price of each ticket?Here we know that the family buys 6 tickets, and they also pay $3 for a parking fee.
The total amount that they spend is $27.
If we remove what the paid for the parking fee, we only will have the cost of the 6 tickets, then we have:
$27 - $3 = $24
Now, we divide this by the number of tickets bought:
$24/6 = $4
Each ticket costs $4.

Find all of the solutions for the following equation. 2 sin q + 3 = sin q + 2
Answer:
q = 270 degrees + 360n where n is an integer
Step-by-step explanation:
2 sin q + 3 = sin q + 2
Subtract sin q from each side
2 sin q - sin q + 3 = sin q + 2
sin q + 3 = 2
Subtract 3 from each side
sin q +3-3 = 2-3
sin q = -1
Take the inverse sin of each side
sin ^-1 (sin q) = sin^-1 (-1)
q = 270 degrees + 360n where n is an integer
A used car dealer sells SUVs and cars. Of all the vehicles, 90% are cars. Of all the vehicles 40% are red cars. What is the probability that a car chosen at random is red? Round your answer to the nearest tenth of a percent.
Answer:
44.4%
Step-by-step explanation:
To calculate this, we proceed as follows.
we use the probability equation below;
P(A|B) = P(A and B) / P(B)
Applying the above to the scenario at hand;
P(red | car) = P(red and car) / P(car)
P(red and car) = 40% or simply 40/100 = 0.4
P(car) = 90% = 90/100 = 0.9
P(red | car) = 0.4/0.9
P(red | car) = 0.4444 which is = 44.44% ; to the nearest tenth of a percent = 44.4%
To find the probability of a randomly chosen car being red, you divide the percentage of red cars by the percentage of all cars. The calculation results in 44.4%, which is the probability that a car is red.
Explanation:To find the probability that a car chosen at random is red, we use the information provided: 90% of all vehicles are cars, and 40% of all vehicles are red cars. To determine the probability of a randomly selected car being red, we must calculate the percentage of red cars within the group of all cars.
This is done by dividing the percentage of red cars by the percentage of all cars, which gives us the probability that a car, given it's a car, is red.
The calculation is (40% / 90%) × 100, which simplifies to 44.4%. Rounded to the nearest tenth of a percent, the probability is 44.4%.
