El acero de alta resistencia es el principal material de los submarinos actuales, con un límite de profundidad de 250 a 400 m para que no haya ningún riesgo de explosión. Si se sabe que la distancia entre los 2 barcos es de 188 m y que las distancias de los barcos hasta el submarino son de 152 y 192 m respectivamente. Determina si el submarino corre algún riesgo de explosión, justificando la respuesta al mencionar la profundidad a la que se encuentra el submarino.
A cone has a radius of 12 inches and a slant height of 20 inches. What is the approximate surface area of the cone?
Answer:
2009.6 in²
Step-by-step explanation:
The surface area, SA of a cone is obtained using the formular :
SA = πr² + πrl
Where ; r = Radius = 20 inches ; l = slant height = 12 inches
SA = π*20² + π*20*12
SA = 400π + 240π
Take π = 3.14
SA = (400*3.14) + (240*3.14)
SA = 1256 + 753.6
SA = 2009.6 in²
Tawana has $325.54 in her checking account. She must keep a balance of at least $300 to avoid a fee. She plans to write a check to pay her to pay her credit card bill of $125.43. how much must Tawana deposit in her checking account to maintain atleast the minimum balance?
hi
Answer: To pay her bill with the minimum balance to avoid the fee, she needs the total amountof $300+$125.43=$425.43. But she only has $325.54. So, the extra minimum amount she needs to deposit is 425.43-325.54=$99.89.
Hence, the answer is $99.89.

If 20.0 mL of a 5.0M HCl solution are required to neutralize 10.0 mL of a NaOH
solution, calculate the molarity of the NaOH solution.
20.0 mL of 5.0 M HCl solution contains
0.0200 L * 5.0 M = 0.10 mol
of HCl.
Mixing the HCl and NaOH solutions results in
HCl + NaOH ==> NaCl + H2O
which is to say 0.10 mol of HCl reacts with 0.10 mol of NaOH. If only 10.0 mL of NaOH solution is required, then its molarity x is such that
0.0100 L * x M = 0.10 mol => x = 10. M

the rectangle with 2 row nd each raw has 6 square each sudw of square is 1 cm determine the perimeter of rectangle and area of square
Answer:
Perimeter of rectangle is 16 cm and the area of square is 1 cm^2
Step-by-step explanation:
Here, we want to get the perimeter of rectangle and area of square
From the question, the rectangle has 2 rows of 6 squares each; So we have the length as 2 cm and the width as 6 * 1 cm = 6 cm
So the rectangle is 6 cm by 2 cm
The perimeter of a rectangle is 2(l + b)
so, we have 2(6 + 2) = 2(8) = 16 cm
The area of the square is simply the side length raised to the power of 2
we have this as 1^2 = 1 cm^2
hi i need help !! what can my equation be ? thank u <3
Sam is 34 years younger than Ashton. 4 years ago, Ashton's age was 3 times Sam's age. How old is Sam now?
Answer:
21years old
Step-by-step explanation:
Let Sam's age be x
Let Ashton present age be y
If Sam is 34 years younger than Ashton then;
x = y - 34 .... 1
If by 4 years ago, Ashton's age was 3 times Sam's age then;
Sam = x - 4
Ashton = y - 4
y-4 = 3(x-4)
y-4 = 3x - 12 ....2
Substitute 1 into 2;
y-4 = 3(y-34)-12
y-4 = 3y-102-12
y-4 = 3y - 114
y-3y = -114 + 4
-2y = -110
y = 110/2
y = 55
Since x = y- 34
x = 55-34
x = 21
Hence Sam will be 21years old now
Solve for the variable: p - 4.2 = 2. Show your work
Answer:
6.2
Step-by-step explanation:
P - 4.2 =2
we have to no separate the variables and constants
so , when we move 4.2 to the other side ( other side of 2) it will be something like this
p = 2+4.2
as you can wee when we moved 4.2 to the other side the operation changed from ,minuus to plus sign .
now just do what it says
formula :
=p-4.2=2
=p = 2+4.2
= 2+ 4.2= 6.2
so,
p=6.2
write the formula , I think no need to write explanation

Pam's eye-level height is 324 ft above sea level, and Adam's eye-level height is 400 ft above sea level. How much farther can Adam see to the horizon? Use the formula d = StartRoot StartFraction 3 h Over 2 EndFraction EndRoot, with d being the distance they can see in miles and h being their eye-level height in feet. 1 mi StartRoot 6 EndRoot mi 19 mi 19 StartRoot 6 EndRoot mi
Answer:
B. StartRoot 6 EndRoot mi
√6 mi
Step-by-step explanation:
A. 1 mi
B. StartRoot 6 EndRoot mi
C.19 mi
D. 19 StartRoot 6 EndRoot mi
d = √(3h/2)
Where,
d = distance they can see in miles h = their eye-level height in feet
Pam:
h = 324 ft
d = √(3h/2)
d = √{(3 * 324)/2}
= √972/2
= √486
= √(81 * 6)
= √81 * √6
= 9√6 mi
Adam:
h = 400 ft
d = √(3h/2)
d = √{(3 * 400)/2}
= √1200/2
= √600
= √(100 * 6)
= √100 * √6
= 10√6 mi
How much farther can Adam see to the horizon?
Adam - Pam
= 10√6 - 9√6
= √6 mi
Does the point (3 , 4) lie on the line
y = 2x -1?
Answer:
No
Step-by-step explanation:
y = 2x -1
Substitute the point into the equation
4 = 2(3) -1
4 = 6-1
4 =5
This is not a true statement so the point is not on the line

Bob eats 1/4 of a pie and later eats 2/5 of the pie. What fractions remains?
Answer:
9/20
Step-by-step explanation:
After Bob eats 1/4 of the pie, he has 3/4 left. 2/5 of 3/4 is the same as (2/5)*(3/4) because "of" is used as multiplication in math. (2/5)*(3/4)=6/20, so he ate 6/20 of the pie. To get the answer, you need to solve 1-(1/4+6/20)=
1-(5/20+6/20)=20/20-11/20=9/20. I hope this helps and sorry if I made a mistake. :)

James can write 6 paragraphs in 24 minutes.
Using the same unit rate, how many paragraphs can James write in 16 minutes?
Lets find out how many a minute. 3 in 12 minutes, 1 in 4 minutes, so 1/4th of a paragraph per minute.
Now 1/4 times 16 = 4. So he can write 4!

A triangular parcel of land has side lengths of 100, 580, and 600 feet. Approximate the area of the land. Round your answer to the nearest foot.
Answer:
28800 square feet
Step-by-step explanation:
We solve this using the Heron's formula
Area of a Triangle = √s(s - a)(s - b)(s - c)
s = a + b + c/2
s = 100 + 580 + 600/2 = 640
Area of the land(Triangle) = √640 × (640 - 100)(640 - 580)(640 - 600)
= √640 × (540) ×( 60) × (40)
= √(829440000)
= 28800 square feet
Therefore, the approximate the area of the land is 28800 square feet.
