The water flow rate of a regular shower head is 3.5 gallons per minute. At
this rate, it would cost $1.90 for the water used for a 10-minute shower.
What is the cost, rounded to the nearest cent, of 1 gallon of water?
Answer: 5 cents
Step-by-step explanation:
Given
Flow rate of water is [tex]3.5\ gal/min[/tex]
At this rate it cots [tex]\$1.90[/tex] for 10 minutes
Volume that flown in this time
[tex]\Rightarrow V=3.5\times 10\\\Rightarrow V=35\ \text{Gallons}[/tex]
So, [tex]\$1.90[/tex] is charged for 35 gallons of water
Using unitary method, 1 gallon costs
[tex]\Rightarrow 1\ \text{gallon}=\dfrac{1.9}{35}\\\\\Rightarrow 1\ \text{gallon}=\$0.0542\ \text{or}\ 5.4\ \text{cents}\\\text{Round off to nearest cent}\\\Rightarrow 1\ \text{gallon}=5\ \text{cents}[/tex]
Playing with toy alphabet blocks, Dani mixes four of the ABCDE blocks into some combination (doesn't care about the order.) Then she takes the XYZ blocks and carefully puts these into a specific order. How many different outcomes are possible for this arrangement of seven blocks?
Answer:
The total outcomes that are possible for this arrangement of seven blocks are 5C4 * 4! * 3!
Step-by-step explanation:
Given
Out of five blocks i.e ABCDE, four blocks need to be drawn.
Hence the possible ways of drawing four blocks out of total set of 5 blocks is
5C4
Now, the total number of ways of arranging these selected four blocks is 4!
The total number of ways of arranging three blocks is 3!
Hence, the total outcomes that are possible for this arrangement of seven blocks are 5C4 * 4! * 3!

Find the value of x. (Type an integer or decimal.)
Answer:
70
Step-by-step explanation:
An angle formed by 2 tangent lines is equal to one half the measure of the major arc minus the measure of the minor arc.
we are given the minor arc ( 110 ) however we are not given the major arc.
Because circles make a 360 degree rotation we can find the major arc by subtracting the measure of the minor arc from 360
Thus, major arc = 360 - 110 = 250
Now that we have identified the major and minor arc we can find x
Recall that x = 1/2 ( major arc - minor arc )
Thus, x = 1/2 ( 250 - 110 )
250 - 110 = 140
140 / 2 = 70
Hence, x = 70

Use SOH-CAH-TOA to find the missing side. Step by step.
Answer:
[tex]180.49[/tex]
Step-by-step explanation:
SOH-CAH-TOA:
In right triangles only:
The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)
The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)
Since we're given an angle, its opposite side, and its adjacent side, we'll use tangent to solve for [tex]x[/tex]:
[tex]\tan 14^{\circ}=\frac{45}{x},\\x=\frac{45}{\tan 14^{\circ}},\\x\approx \boxed{180.49}[/tex].
Use the terms free fall, gravitational acceleration, air resistance and
terminal velocity to explain:
1. why whether a wing suit pilot is in free fall or not, and
2. how a parachute allows him/her to land on the ground safely.
Write a few sentences here:
Answer:
1. A wingsuit pilot is not in freefall.
2. The parachute increases air resistance, decreasing the pilot's acceleration, thus decreasing terminal velocity and allowing the pilot to land safely.
Step-by-step explanation:
1. An object is in freefall when the only force acting on it is the force of gravity. An object does not necessarily need to moving at a certain speed to be in freefall. Because the wingsuit pilot's wingsuit creates a heavy amount of air resistance, the force of gravity is not the only force acting on the object. Therefore, the object is not in freefall.
2. By increasing the surface area or cross-section perpendicular to the force of gravity, the parachute creates a heavy amount of air resistance. Since air resistance acts opposite in direction to the force of gravity, the pilot will have a lower terminal velocity and will reach the ground at a dramatically lower speed, thus allowing them to land safely.

Parallelogram CDEF is formed inside of rectangle AEBC to create triangle ADC and triangle EBF as shown in the model below.
How much greater is the area of parallelogram CDEF than the area of triangle EBF in square centimeters?
The areas of the parallelogram CDEF and triangle EBF can be calculated
from which the difference between the areas can be found.
Response:
The amount by which the area of parallelogram CDEF is greater than the area of triangle BF is C. 493.5 cm².Which methods can be used to evaluate the areas of the regular shapes?Area of the parallelogram CDEF = CF × EB
Which gives;
Area of the parallelogram CDEF, A = 29 cm × 21 cm = 609 cm²
Area of triangle EBF = [tex]\mathbf{\frac{1}{2}}[/tex] × BF × EB
Which gives;
Area of triangle EBF, [tex]A_{EBF}[/tex] = [tex]\frac{1}{2}[/tex] × 11 cm × 21 cm = 115.5 cm²
The difference in area, ΔA = A - [tex]\mathbf{A_{EBF}}[/tex]
Which gives;
ΔA = 609 cm² - 115.5 cm² = 493.5 cm²
The area of parallelogram CDEF is 493.5 cm² greater than the area of triangle BFThe correct option is C. 493.5 cm²Learn more about the area of regular shapes here:

know how long it will take an investment of $1,000
to earn $500 in interest if the yearly interest rate is 4.75%. Please answer fast and show work I will mark you as brain
Answer:
It will take 8.73 years.
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,000
Future value (FV)= $1,500
Interest rate (i)= 4.75% compounded annually
To calculate the time required for the initial investment to reach the objective, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= ln(1,500/1,000) / (1.0475)
n= 8.73
It will take 8.73 years.
