Answer:
- 12 meters
28 meters
40 meters
Step-by-step explanation:
Given that:
A fish is 12 meters below the surface of the ocean. What is its elevation?
Position of fish = 12 meters below the surface = - 12 ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + (- 12)
= - 12 meters
2. A sea bird is 28 meters above the surface of the ocean. What is its elevation?
Position of bird = 28 meters below the surface = (28) ;
Sea level = 0
Elevation = sea level + position
Elevation = 0 + 28
= 28 meters
3. If the bird is directly above the fish, how far apart are they?
If bird is directly above the fish;
Distance between bird and fish :
Elevation of bird - elevation of fish
28 - (-12)
28 + 12
= 40 Meters

Which equation represents a line which is perpendicular to the line
2x + y = -5?
Answer:
y = [tex]\frac{1}{2}[/tex] x - 5
Step-by-step explanation:
Given expression:
2x + y = -5
Find the equation of the line perpendicular
Solution:
A line perpendicular to this line will have a negative inverse slope;
Equation of any line is given as;
y = mx + c
y and x are the coordinates
m is the slope
c is the intercept
Re-write;
2x + y = -5
y = -2x - 5
Now,
we know that the slope is -2
A line perpendicular will have a slope of [tex]\frac{1}{2}[/tex] ;
So;
Equation of the line is;
y = [tex]\frac{1}{2}[/tex] x - 5

if John bought 2.5 kgs of rice for $7.50, then what is the unit price of rice?
Answer:
$3 per kg of rice
Step-by-step explanation:
To find the unit price of the rice, you have to divide the price of 2.5 kgs by 2.5 to get to the base unit of 1 kg.
7.50/2.5=3
So, it is $3 for every kg of rice.

You are watering a garden. The height h (in feet) of water spraying from the garden hose can be modeled by h(x)=−0.1x2+0.7x+3, where x is the horizontal distance (in feet) from where you are standing. You raise the hose so that the water hits the ground 1 foot farther from where you are standing. Write a function that models the new path of the water.
Answer:
[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]
Step-by-step explanation:
Given
[tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]
Required
Determine the new function
From the question, we understand that the new function wants the water to hit the ground 1 ft farther.
1 ft farther implies x + 1
So, in the given function, we substitute x + 1 for x in [tex]h(x) = -0.1x^2 + 0.7x + 3[/tex]
This gives:
[tex]h(x + 1) = -0.1(x + 1)^2 + 0.7(x + 1) + 3[/tex]
Expand Bracket
[tex]h(x + 1) = -0.1(x + 1)(x + 1) + 0.7(x + 1) + 3[/tex]
[tex]h(x + 1) = -0.1(x^2+2x+1) + 0.7(x + 1) + 3[/tex]
[tex]h(x + 1) = -0.1x^2-0.2x-0.1 + 0.7x + 0.7 + 3[/tex]
Collect Like Terms
[tex]h(x + 1) = -0.1x^2-0.2x + 0.7x + 0.7 + 3-0.1[/tex]
[tex]h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]
Hence, the new function is:
[tex]g(x) = h(x + 1) = -0.1x^2 + 0.5x + 3.6[/tex]
[tex]g(x) = -0.1x^2 + 0.5x + 3.6[/tex]
The new model for path of water will be, [tex]h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]
To understand more, check below explanation.
Height function:The height h (in feet) of water spraying from the garden house can be modeled by,
[tex]h(x)=-0.1x^{2} +0.7x+3[/tex]
where x is the horizontal distance (in feet) from where you are standing.
Since, you raise the hose so that the water hits the ground 1 foot farther from where you are standing.
So that, new function will be,
[tex]h(x+1)=-0.1(x+1)^{2} +0.7(x+1)+3\\\\h(x+1)=-0.1(x^{2} +2x+1)+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} -0.2x-0.1+0.7x+0.7+3\\\\h(x+1)=-0.1x^{2} +0.5x+3.6[/tex]

A. 2,555 hours
B. 6,205 hours
C. 8,760 hours
D. 5,840 hours
Answer:
B
Step-by-step explanation:
24 - 7 = 17.
If there are 365 days in a year, sometimes 366, you would multiply 17 by 365 or 366.
17 x 365 = 6205
17 x 366 = 6222.

There are 330 walnuts in 6 bags. If each bag has the same number of walnuts, how many walnuts are in 2 bags? 45 walnuts 55 walnuts 110 walnuts 220 walnuts
Answer:
110 walnuts
Step-by-step explanation:
There are 330 walnuts in 6 bags.
Each bag has the same number of walnuts
Hence, the number did walnuts in one bag=
6 bags = 330 walnuts
1 bag = x walnuts
Cross Multiply
6 × x = 1 × 330 walnuts
x = 330 walnuts/6
x = 55 walnuts
Each bag contains 55 walnuts
The number of walnuts that are in 2 bags is calculated as:
1 bag = 55 walnuts
2 bags =
2 × 55 walnuts
= 110 walnuts
There are 110 walnuts in 2 bags.

Challenge You have 2 different savings accounts. For Account A, the simple interest earned after months is $. For Account B, the simple interest earned after months is $. If the interest rate is % for Account A and % for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Answer and Step-by-step explanation:
The computation is shown below;
As we know that
The simple interest is
Simple interest = Principal × rate × time
For Account A, the principal would be
2 = Principal × 3.2% × 3
So, the principal is $20.83
For account B, the principal would be
38.50 = Principal × 2.2% × 30
So, the principal is $58.33
Now the interest for both the accounts are as follows
For account 1
= $20.83 × 3.2%
= $0.67
And, for the account 2
= $58.33 × 2.2%
= $1.28
As it can be seen that the account 2 has the highest interest
The same is to be considered
for what value of a does the equation 3(2x-a)=2(3x+12) have infinitely many solutions to x
Answer: a = -8
3(2x - a) = 2(3x + 12)
⇔ 6x - 3a = 6x + 24
⇔ - 3a = 24
⇔ a = -8
Step-by-step explanation:
Answer:
X=24
Step-by-step explanation:
3(2x-a)=2(3x+12)
6x-3a=6x+24
-6x both sides.
-3a=x+24
Get rid of the -3a.
x+24
divide by x both sides.
x=24

Provided that 2a+b=7 and
3a - 2b=3, by how much is 7a
greater than 10?
Answer:
a=2.42, b=2.16
16.94>10
Step-by-step explanation:
We are given: 2a+b =7 and 3a-2b=3 , We need to find how much is 7a greater than 10.
First we need to solve equations to find value of a
[tex]2a+b =7---eq(1)\\ 3a-2b=3---eq(2)[/tex]
Multiply eq(1) by 2 and add both equations
[tex]4a+2b =14\\ 3a-2b=3\\------\\7a=17\\a=\frac{17}{7}\\a=2.42[/tex]
Putting value of a in eq(1) to find b
[tex]2a+b=7\\2(2.42)+b=7\\4.84+b=7\\b=7-4.84\\b=2.16[/tex]
Now, a = 2.42 and b=2.16
Finding by how much is 7a greater than 10
[tex]7a>10[/tex]
Putting a = 2.42
[tex]7a>10\\7(2.42)>10\\16.94>10[/tex]
