A submarine sits at –300 meters in relation to sea level. Then it descends 115 meters. What is its new position in relation to sea level? Negative 415 m Negative 185 m Negative 115 m Negative 100 m
Answer:
[tex]New\ Position = -415m[/tex]
Step-by-step explanation:
Given
[tex]Position= -300m[/tex]
[tex]Descend = 115m[/tex]
Required
Determine the new position
It descends means that it moved in the downward position.
So, the new position is:
[tex]New\ Position = Position - Descend[/tex]
[tex]New\ Position = -300m - 115m[/tex]
[tex]New\ Position = -415m[/tex]
Hence, the new position f the submarin is -415m

People who understand please reply
a = 49.0 rounded to 1 DP
b= 7.62 rounded to 2 DP
Find the minimum of a - b
Answer:
The minimum of a - b is 41.325
Step-by-step explanation:
Let us solve the question using upper and lower boundaries
∵ a = 49.0 rounded to 1 decimal place
∵ 1 decimal place means 0.1
→ Divide 0.1 by 2
∵ 0.1 ÷ 2 = 0.05
→ Add 0.05 to the rounded number to get the upper boundary
∵ 49.0 + 0.05 = 49.05
∴ The upper boundary = 49.05
→ Subtract 0.05 from the rounded number to get the lower boundary
∵ 49.0 - 0.05 = 48.95
∴ The lower boundary = 48.95
∴ The range of a is 48.95 ≤ a < 49.05
∵ b = 7.62 rounded to 2 decimal places
∵ 2 decimal place means 0.10
→ Divide 0.01 by 2
∵ 0.01 ÷ 2 = 0.005
→ Add 0.005 to the rounded number to get the upper boundary
∵ 7.62 + 0.005 = 7.625
∴ The upper boundary = 7.625
→ Subtract 0.005 from the rounded number to get the lower boundary
∵ 7.62 - 0.005 = 7.615
∴ The lower boundary = 7.615
∴ The range of b is 7.615 ≤ b < 7.625
To find the minimum value of a - b, use the smallest value of a and the greatest value of b
∵ The minimum of a - b = lower boundary of a - upper boundary of b
∴ The minimum of a - b = 48.95 - 7.625
∴ The minimum of a - b = 41.325
∴ The minimum of a - b is 41.325
Select all the points that are on the graph of the line
-2x + 5y = -15
A(0,5)
B(0,-3)
C (-5, -1)
D (-5,-5)
E (10,-1)
F (-10,7)
Answer:
(0,-3), (-5,-5)
Step-by-step explanation:
Plug in x and y and see in which case = -15
-2(0)+5(5)= 25 no
-2(0)+5(-3)= -15 yes
-2(-5)+5(-1)= 5 no
-2(-5)+5(-5)= -15 yes
-2(10)+5(-1)= -25 no
-2(-10)+5(7)= 55 no
After earning interest, the balance of an account is $420. The new balance is 7/6 of the original balance.
Write an equation that can be used to find the original balance b of the account.
420=____
What was the original balance of the account?
$__
How much interest did the account earn?
$__
Answer:
Equation: 420 = 7/6b, Original balance: $360, Interest earned: $60.
Step-by-step explanation:
Since 420 is 7/6 of the original balance, and of means mulitply, we can make this into an equation, the equation is 420 = 7/6b. Let's solve the equation for b. Multiply both sides by 6 to get 2520 = 7b. Now, let's divide both sides by 7. This gets us 360 = b. This means the original balance was $360. Now, let's find the interest earned. We know that 420 is 7/6 of 360, so that means the interest earned was 1/6 of the original balance. Let's make sure, first. 360/6 is 60, and 360+60 is 420, so everything checks out.

A Caribbean resort has a nightly limbo contest on the beach, Participants must be less than 64 inches tall. The distribution of heights of adult American men is approximately normal with mean 69 inches and standard deviation 2.5 inches. About what percent of adult American males could enter this contest?
Answer:
2.23%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = < 64 inches
μ is the population mean = 69
σ is the population standard deviation = 2.5
Since: Participants must be less than 64 inches tall.
For x < 64 inches
z = 64 - 69/2.5
z = -2
Probability value from Z-Table:
P(x<64) = 0.02275
Converting to percentage
= 0.02275 × 100
= 2.275%
Approximately = 2.23%
Because participants must be less than 64 inches tall to participate in this limbo contest, the percent of adult American males thag could enter this contest is 2.23%
Answer:
2.23

Stephen and Bridget win some money and share it in the ratio 1:3. Stephen gets £11. How
much did they win in total?
Answer:
£44
Step-by-step explanation:
We have been given the ratio 1 : 3 , where 1 is stephens value and 3 is bridgets value.
We have told that stephen gets £11.
The relationship between stephens 'value' of 1 and the amount of money that he actually gets (11) is x11.
Therefore we must also x11 to Bridgets value.
11 x 3 = £33
Now, we add the two answers to find how much they won in total.
£33 + £11 = £44
hope this helps :)

Assume there is a 50% chance of having a boy. Find the probability of
exactly two boys in three births.
Answer:
0.375
Step-by-step explanation:
Given that there is 50% chance of having a boy in a single birth.
Let it be represented by p, so
p=50%=0.5
According to Bernoulli's theorem, the probability of exactly r success in n trials is
[tex]P(r)=\binom {n}{ r} p^r(1-p)^{n-r}[/tex]
where p is the probability of success.
So, the probability of exactly 2 boys (success) in a total of 3 birth (trials) is
[tex]P(r=2)=\binom {3}{ 2} p^2(1-p)^{3-2}[/tex]
As p=0.5, so
[tex]P(r=2)=\binom {3}{ 2} (0.5)^2(1-0.5)^{3-2} \\\\=\binom {3}{2} (0.5)^2(0.5)^{1} \\\\=3\times 0.5^3[/tex]
=0.375
Hence, the probability of exactly 2 boys in a total of 3 birth is 0.375.
Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 miles apart when they stop, how many miles west did Jill drive? Show all work in solving the problem.
Answer:
72 mles
Step-by-step explanation:
For better understanding, I'll make use of an attachment.
From the attachment,
O represents the start point
[tex]OB = 30[/tex] --- Jack
[tex]AB = 78[/tex] -- Distance between them
Required
Find OA; Jack's distance
To do this, we make use of Pythagoras theorem
[tex]AB^2 = OA^2 + OB^2[/tex]
This gives:
[tex]78^2 = OA^2 + 30^2[/tex]
[tex]6084 = OA^2 + 900[/tex]
Subtract 900 from both sides
[tex]OA^2= 6084 - 900[/tex]
[tex]OA^2= 5184[/tex]
Take square roots
[tex]OA = \sqrt{5184}[/tex]
[tex]OA = 72[/tex]
Hence, Jill drove 72 miles
