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

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

A company that makes hair-care products had 6,000 people try a new shampoo. Of the 6,000 people,
36 had a mild allergic reaction. What percent of the people had a mild allergic reaction?
% of the people had a mild allergic reaction,
Answer:
0.6% of the people had a mild allergic reaction.
Step-by-step explanation:
Given that:
Number of people who tried hair care products = 6000
Number of people who had reaction = 36
Percent of people = [tex]\frac{Number\ of\ people\ with\ reactions}{Total\ number}*100[/tex]
Percent of people = [tex]\frac{36}{6000}*100[/tex]
Percent of people = 0.6%
Hence,
0.6% of the people had a mild allergic reaction.
Find the percent of change. Round to the nearest whole percent if necessary. State whether the percent of change is an increase () or decrease (0)

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
A rectangular prism is 1 inch long and 2 inches wide. Its volume is 12 cubic inches. What is the height of the rectangular prism?
Answer: 6 inches
Explanation:
12 = 1(2)h
12 = 2h
12 ÷ 2 = 2h ÷ 2 (isolating the H term)
6 = h

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

Answer:
y = -x + 9
Step-by-step explanation:
✔️Find the slope using (9, 0) and (7, 2):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 0}{7 - 9} = \frac{2}{-2} = -1 [/tex]
Slope (m) = -1
✔️Find the y-intercept (b):
The line intercepts the y-axis when y = 9. Therefore, y-intercept (b) = 9
✔️Substitute m = -1 and b = 9 into y = mx + b
Thus,
y = -1(x) + 9
y = -x + 9

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.
