Given
Their vacation savings account currently has a balance of $2,764.
The family would like to have at least $5,000.
To findThe amount of money the family still needs to save.
How to find the amount of money the family still needs to save?Forming the equation, we get
Let x be the amount needed to save. then
x + 2764 ≥ 5000
On simplifying, we get
x + 2764 ≥ 5000
x ≥ 5000 - 2764
x ≥ 2236
Thus, the amount of money the family still needs to save is $2236.

Hope it helps...A 4. 9-mm-wide swimming pool is filled to the top. The bottom of the pool becomes completely shaded in the afternoon when the sun is 20 ∘∘ above the horizon.
The depth of the swimming pool that is filled to the top is; 4 m
Snell's Law
I have attached a schematic diagram showing this question.
The correct width of the pool is 4 meters. Thus; w = 4 m
Incident Angle; θ₁ = 20°
A right angle is 90° and so the angle θ₂ is calculated from;
θ₂ = 90° - θ₁
θ₂ = 90° - 20°
θ₂ = 70°
We can use snell's law formula to find θ₃.
Thus;
n₁sinθ₂ = n₂sinθ₃
where;
n₁ is refractive index of air = 1
n₂ is refractive index of water = 1.33
Thus;
1*sin 70 = 1.33*sin θ₃
sin θ₃ = (sin 70)/1.33
Solving this gives;
θ₃ = 44.95°
By usage of trigonometric ratios we can find the depth of the pool using;
w/d = tan θ₃
Thus;
d = w/(tan θ₃)
d = 4/(tan 44.95)
d ≈ 4 m

A system of equations is shown below.
y=-2x + 6
6x + 3y = 18
What is the solution to the system of equations?
(Show work)
Answer:
Step-by-step explanation:
First, we need to look at the simpler equation. We see that the top equation is the simpler one.
y=-2x + 6
Now we plug that equation with the other one.
6x + 3(-2x + 6) = 18
6x -6x + 18 = 18
18 = 18
Since we see that 18 = 18. We know that this equation is a true equation. We can plug the y-variable in first and it will still be a true statement.

~[tex]\frak{Amphitrite1040:)}[/tex]The percentage of increase from 75 to 110 is approximately 46.7%.
The correct option is 46.7%.
To calculate the percent of increase from 75 to 110, we can use the following formula:
Percent Increase = (New Value - Old Value) / Old Value * 100
Substituting the values, we have:
Percent Increase = (110 - 75) / 75 * 100
Calculating the numerator and denominator separately:
Numerator = 110 - 75 = 35
Denominator = 75
Substituting these values into the formula:
Percent Increase = (35 / 75) x 100 ≈ 46.7%
Therefore, the percentage of increase from 75 to 110 is approximately 46.7%.
It's important to note that the percent of the increase represents the relative change in value from the old value to the new value, expressed as a percentage of the old value. In this case, the value has increased by approximately 46.7% from 75 to 110.

Malik used these steps to solve the system of equations. 2 x 4 y = 20. 5 x minus 3 y = 11. Step 1 6 x 12 y = 60. 20 x minus 12 y = 44. Step 2 Step 3 x = 4 Step 4 2 (4) 4 y = 20. 8 4 y = 20. 4 y = 12. Y = 3. Step 5 The solution is (4, 3). What needs to be done in step 2? Divide both sides of the equations in step 1 by the same number to eliminate one variable. Multiply both sides of the equations in step 1 by the same number to eliminate one variable. Add the equations in step 1 to eliminate one variable. Subtract the equations in step 1 to eliminate one variable.
The "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
Given to us
2x + 4y = 205x - 3y = 11Step 1: Multiply the first equation with 3, while the second equation with 4,
6x + 12 y = 60
20x - 12 y = 44
Step 2: Add both the equations,
(6x + 12y) + (20x - 12y) = 60+44
Step 3: caluculate the value of x,
x = 4
Step 4: Substitute the value of x in equation 1,
2(4) + 4y = 20
8 + 4y = 20.
4y = 12
Y = 3
Step 5: The solution is (4, 3).
Hence, the "step 2" that Malik should take in order to solve the given system of equations is to add both equations.
