Step-by-step explanation:
A submarine is 150 below sea level while an airplane is 375 above sea level. What is the difference between the height of the submarine and the airplane?
Answer:
[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]
So then the distance between the submarine and the airplace is 525 m
Step-by-step explanation:
For this case we know that the submarine is 150 m below the sea level and the airplane is 375 m above the sea level and we want to find the difference between the heights and we got:
[tex] D= 375 - (-150) m = 375m +150 m= 525 m[/tex]
So then the distance between the submarine and the airplace is 525 m

Favorite Ice Cream Flavors
How many more of Ursula’s classmates chose chocolate than chose vanilla?
Answer:
8
Step-by-step explanation:
Vanillas percentage is 26%
26% of 50 is 13
Chocolates percentage is 42%
42% of 50 is 21
21-13=8
Using proportions, it is found that 8 more of Ursula’s classmates chose chocolate than chose vanilla.
In total, there are 50 students.
42% choose chocolate, hence:[tex]0.42(50) = 21[/tex]
That is, 21 choose chocolate.
The sum is 100%, hence the percentage that choose vanilla is:
[tex]x + 14 + 18 + 42 = 100[/tex]
[tex]x = 100 - 74[/tex]
[tex]x = 26[/tex]
26%, out of 50, hence:
[tex]0.26(50) = 13[/tex]
13 choose vanilla.
21 - 13 = 8.
8 more of Ursula’s classmates chose chocolate than chose vanilla.

what is the perimeter of a semi-circle with a diameter of 14 units
Answer:
35.98
Step-by-step explanation:
To find the perimeter take 1/2 of the circumference plus the length of the diameter
P = 1/2 * pi *d + d
=1/2 pi 14 +14
= 7pi +14
Letting pi = 3.14
7(3.14) + 14
21.98 +14

The length and width of a rectangular patio are, (x + 7) feet and (x + 9) feet, respectively. If the area of the patio is 150 square feet, what are the dimensions of the patio? Enter the dimensions to two decimal places. The equation has real solution(s). The width (shorter dimension) of the patio is feet. The length (longer dimension) of the patio is feet.
Answer:
The width of the patio is 11.29 feet while the length of the patio is 13.29 feet
Step-by-step explanation:
Mathematically, the area of the patio can be calculated by multiplying the length by the breadth of the patio
Thus we have ;
(x + 7)(x + 9) = 150
x^2 + 7x + 9x + 63 = 150
x^2 + 16x + 63 = 150
x^2 + 16x + 63 -150 = 0
x^2 + 16x -87 = 0
we can use the quadratic formula to solve this completely
x = {-b ± √(b^2 - 4ac)}/2a
where a = 1, b = 16 and c = -87
Plugging the values we have
x = {-16 ± √(16^2 - 4(1)(-87)}/2
x = {-16 ± √(256+ 348)}/2
x = {-16 ± √(604}/2
x = (-16 + 24.58)/2 or (-16-24.58)/2
x = 4.29 or -20.29
Choosing x = -20.29 will make our dimensions negative, so we ignore it and make do with the positive value only
Thus our dimensions are 4.29 + 7 and 4.29 + 9
This is equal to 11.29 feet and 13.29 feet respectively

The elevation at the summit of Mount Whitney is 4,418 meters above sea level. Climbers begin at a trail head that has an elevation of 2,550 meters above sea level. What is the change in elevation, to the nearest foot, between the trail head and the summit?
(1 foot =0.3048 meters) *
A. 1868 ft
B. 569 ft
C. 6,128 ft
D. 6,129 ft
Answer:
D
Step-by-step explanation:
Firstly, to answer this question, we need to calculate the change in elevation.
Let’s just think of the question as, the distance from the foot of the mountain to the top is 4,418 meters. Now we have climbers starting at a height of 2,550 meters. We now need to know the difference or the distance to which they have climbed.
To calculate this is quite straightforward, all we need do is to subtract the starting point from the end position.
Mathematically that would be 4,418 - 2,550 = 1,868 meters
Now our answer need be in foot. we have a conversion system given in the question already.
1 foot = 0.3048 meters
x foot = 1,868 meters
x = 1,868/0.3048
x = 6,128.6 feet which is approximately 6,129 feet

You roll a six-sided die. What is the probability that it is a 5 or an even number? Write your answer as a decimal rounded to the nearest
thousandth
Answer:
.667
Step-by-step explanation:
4/6 = 2/3 = .667
The probability that it is a 5 or an even number is 5/6 or 0.834 if
you roll a six-sided die.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Number of total outcomes = 6
P(5) = 1/6
P(even) = 4/6
The probability that it is a 5 or an even number:
P = 1/6 + 4/6 = 5/6
P = 0.834
Thus, the probability that it is a 5 or an even number is 5/6 or 0.834 if
you roll a six-sided die.

BALLOON The angle of depression from a hot air balloon in the air to a person on the ground is 41°. If the person steps back 12 feet, the new angle of depression is 25°. If the person is 6 feet tall, how far off the ground is the hot air balloon?
Answer:
16.06 ft
Step-by-step explanation:
The figure is attached below.
In triangle ACB:
[tex]tan(41)=\frac{x}{y} \\x=ytan(41)[/tex]
In triangle ADB:
[tex]tan(25)=\frac{x}{y+10} \\(y+10)tan(41)=x[/tex]
Therefore equating both equations gives:
[tex]ytan(41) = (y+10)tan(25)\\ytan(41) = ytan(25)+10tan(25)\\ytan(41)-ytan(25)=10tan(25)\\y(tan(41)-tan(25))=10tan(25)\\y=\frac{10tan(25)}{(tan(41)-tan(25)} =11.5715ft[/tex]
Therefore x = 11.5715*tan(41) = 10.06 ft
The distance of the jot air balloon to ground = 10.06 + 6 = 16.06 ft

Answer: The lenght of the missing side is 4 cm
Step-by-step explanation:
The correct question is:
The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?
So, to answer it we have to apply the next formula:
Perimeter of a rectangle = 2 width + 2 length
Replacing with the values given: (assuming that the side given is the length of the rectangle)
20 = 2(6) + 2x
Solving for x:
20 =12 +2x
20-12 =2x
8 =2x
8/2 =x
4=x
The length of the missing side is 4 cm

A spinner has 5 equal sections numbered 1 to 5. What is the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3?
HELPPPP!!!
Answer:
0.6
Step-by-step explanation:
Given that the spinner has 5 equal sections numbered 1 to 5.
Total Sample Space, n(S)=5Multiples of 2 in 1 to 5 are: {2,4}
Number less than than 3 are:{1,2}
Since we are required to find the probability of the spinner stopping on a number that is a multiple of 2 or is less than 3, we take the union of both sets.
{2,4} [tex]\cup[/tex] {1,2} ={1,2,4}
Number of Outcomes=3
Therefore,
Probability of the spinner stopping on a number that is a multiple of 2 or is less than 3 [tex]=\dfrac{3}{5}=0.6[/tex]
He volume V (in cubic feet) of a right cylinder with a height of 5 feet and radius r (in feet) is given by V=5πr2. Solve the formula for r. Then find the radius of the cylinder when the volume is 770 cubic feet. Round your answer to the whole number.
Answer:
[tex] 770 = 5\pi r^2[/tex]
If we divide both sides by [tex] 5\pi[/tex] we got:
[tex] \frac{770}{5\pi} = r^2 [/tex]
And taking square root we got:
[tex] r = \sqrt{\frac{770}{5\pi}}= 7.001 ft[/tex]
And rounded to the nearest whole number we got 7 ft
Step-by-step explanation:
For this case we know that the hieght of a right cylinder is 5 ft and the volume is given by:
[tex] V = 5 \pi r^2 [/tex]
And we know that the volume [tex] V = 770 ft^3[/tex] and we want to solve for r so we can set up the following equation:
[tex] 770 = 5\pi r^2[/tex]
If we divide both sides by [tex] 5\pi[/tex] we got:
[tex] \frac{770}{5\pi} = r^2 [/tex]
And taking square root we got:
[tex] r = \sqrt{\frac{770}{5\pi}}= 7.001 ft[/tex]
And rounded to the nearest whole number we got 7 ft

a box cost $2.48, but it is on sale for $1.49. How much do you save on one box when bought on sale? Now how much would you save if you bought a second box?
Answer:
1. $0.99
2. $1.98
Step-by-step explanation:
1. From the question we have
Cost of box = $2.48
Selling price = $1.49
That is the box is discounted from $2.48 to $1.49
Therefore, amount saved = $2.48 - $1.49 = $0.99
2. The amount saved from buying a second box is hence;
2 × $0.99 = $1.98
Hence, as the number of boxes bought increases, the amount saved increases
Answer:
The answers to both questions are
1. You save $0.99 on the box when it is purchased on sale
This is calculated by subtracting on-sale price from pre-sale price:
$2.48-$1.49 = $0.99
2. Total amount saved when a second box is purchased on-sale price is derived by multiplying the amount saved on-sale purchase by two:
$0.99 x 2 (boxes)
$0.99 x 2 = $1.98
