3. A new a bank customer with $3,000 wants to open
a money market account. The bank is offering a
simple interest rate of 1.9%
a. How much interest will the customer earn in 20 years?
Answer:
In 20 years, the customer earns 1330
Step-by-step explanation:
I =Prt
the formula for simple interest
P= 3000
r = 1.9% (0.019)
t = 20 years
(3500)(0.019)(20)= 1330

Answer:
29.
Step-by-step explanation:
Given: Lines a and b are parallel and line c is a transversal. Prove: Angle2 is supplementary to Angle8 Horizontal and parallel lines a and b are cut by transversal c. On line a where it intersects line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 1, 2, 4, 3. On line b where it intersects line c, 4 angles are created. Labeled clockwise, from uppercase left, the angles are: 5, 6, 8, 7. What is the missing reason in the proof? Statement Reason 1. a || b, is a transv 1. given 2. ∠6 ≅ ∠2 2. ? 3. m∠6 = m∠2 3. def. of congruent 4. ∠6 is supp. to ∠8 4. def. of linear pair 5. ∠2 is supp. to ∠8 5. congruent supplements theorem corresponding angles theorem alternate interior angles theorem vertical angles theorem alternate exterior angles theorem
Answer:
The correct option is;
Corresponding angles theorem
Step-by-step explanation:
Type of lines of lines a and b = Horizontal and parallel lines
The transversal to a and b = Line c
The angles between a and c labelled clockwise from the upper left quarter segment = 1, 2, 4 and 3
The angles between b and c labelled clockwise from the upper left segment = 5, 6, 8 and 7
Therefore, we have;
Statement [tex]{}[/tex] Reason
1. a║b, c is a transversal [tex]{}[/tex] Given
2. ∠6 ≅ ∠2 [tex]{}[/tex] Corresponding angles theorem
3. m∠6 = m∠2 [tex]{}[/tex] Definition of congruent
4. ∠6 is supp. to ∠8 [tex]{}[/tex] Definition of linear pair
5. ∠2 is supp. to ∠8 [tex]{}[/tex] Congruent supplement theorem
Corresponding angles are the angles located in spatially similar or matching corners of two lines that have been crossed by the same transversal. When the two lines having a common transversal are parallel, the corresponding angles will be congruent.
Steve and Brian are both avid bicyclists. Each week, Steve rides for a total of 2x hours at an average speed of x miles per hour.
sBrian rides 6 more hours a week than Steve, but at an average speed that is 4 miles per hour less than Steve's average speed.
Which of the following functions will give the total distance that Brian rides each week, in miles?
Answer:
m(x) = 2x^2 - 2x - 24
Step-by-step explanation:
We will use the speed formula for this.
d/t = s
d is distance
t is time
s is speed
since we are looking for a function that gives the distance, we must rewrite
the equation to have d on one side of the equation by itself. We will do this by multiplying both sides by t.
(d/t)t = (s)t
which simplifies to:
d = st
Now we must find out what s and t are.
t: Steve's time riding is 2x hours, and Brian's is 6 more hours, so
Brian's time riding is 2x + 6.
so t = 2x + 6.
s: Steve's speed is x mph. Brian's is 4 less than that so
s = x - 4.
Now we can plug in what we know the the formula we made: d=st
d = (2x + 6)(x-4)
now we can FOIL.
(2x)(x)= 2x^2
(2x)(-4)= -8x
(6)(x) = 6x
(6)(-4) = -24
d = 2x^2 - 8x + 6x - 24
simplify:
Answer: d = 2x^2 -2x - 24

When a fraction equals zero
4.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
3•(a-9)
——————— • 7 = 0 • 7
7
Now, on the left hand side, the 7 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
3 • (a-9) = 0
Equations which are never true:
4.2 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.3 Solve : a-9 = 0
Add 9 to both sides of the equation :
a = 9
One solution was found :
a = 9

What is the answer I don’t understand how to do it
Answer:
= -22
Step-by-step explanation:
In a simple way to say it, all you have to do is add.
Remember that two negatives being added together will remain a negative.
Think of a number line, -11 would be on the left side of the 0. If you subtract another 11, you move 11 spaces more to the left. This gives you -22.
Or simply add the 11 and then add the negative sign next to it.
-(11+11)= -22
Hope this helps! :)
Matter is in a liquid state when its temperature is between its melting point and its boiling point. Suppose that some substance has a melting point of -36.14 degrees Celsius and a boiling point of 324.84 degrees Celsius . What is the range of temperatures in degrees Fahrenheit for which this substance is not in a liquid state?
Answer:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.
Step-by-step explanation:
Matter generally exists in either a solid, liquid or gaseous form. With each phase having a certain range of temperature.
Temperature scale of a given substance can be either in Celsius, Fahrenheit or Kelvin. And conversion from one scale to another can be achieved. Example, Celsius scale can be converted to Fahrenheit by:
F = [tex]\frac{9}{5}[/tex] θ + 32
where: F is the equivalent temperature in Fahrenheit, θ is the value of temperature in degree Celsius.
Given that: melting point of the substance = [tex]-36.14^{o}[/tex]C
⇒ F = [tex]\frac{9}{5}[/tex] x [tex]-36.14^{o}[/tex] + 32
= [tex]-33.052^{o}[/tex]F
The boiling point = [tex]324.84^{o}[/tex]C
F = [tex]\frac{9}{5}[/tex] x [tex]324.84^{o}[/tex] + 32
= [tex]616.712^{o}[/tex]F
The melting point of the substance is [tex]-33.052^{o}[/tex]F, and boiling point is [tex]616.712^{o}[/tex]F.
Therefore, the range of temperatures for which the substance is not in a liquid state are:
i. When the temperature is above [tex]616.712^{o}[/tex]F, it changes to gas.
ii. When the temperature is below [tex]-33.052^{o}[/tex]F, it changes to solid.

−(6m+8) =4(17−m)
Answer:
[tex]\boxed{m = -38}[/tex]
Step-by-step explanation:
[tex]-(6m+8) =4(17-m)[/tex]
→ Expand brackets
[tex]-6m-8=68-4m[/tex]
→ Add 8 to both sides to collect the whole numbers
[tex]-6m = 76-4m[/tex]
→ Add -4m to both sides to collect the m terms
[tex]-2m=76[/tex]
→ Divide both sides by -10 to isolate m
[tex]m=-38[/tex]

The units of the floor plan at the right are in feet. Find the
perimeter and area of each room.
a. the kitchen
Kitchen
Bedroom
b. the bedroom
c. the bathroom
20 ft
Main
hallway
d. the closet
Closet
Bathroom
e. What is the area of the main hallway? Explain how
you could find this area using the area of each room
20 ft
Answer:
Step-by-step explanation:
a). Perimeter of the kitchen = total length of all sides
= 4 + 2 + 2 + 6 + 6 + 12 + 10 (Since side of one smallest square = 2 feet)
= 42 ft
Area of the kitchen = Area of the composite figure
= 4² + 2² + (6 × 12)
= 16 + 4 + 72
= 92 square feet
b). Perimeter of bedroom = 2(length + width)
= 2(12 + 8)
= 40 feet
Area of the bedroom = Length × Width
= 12 × 8
= 96 square feet
c). Perimeter of the bathroom = 2(9 + 4) = 26 feet
Area of the bathroom = 9 × 4 = 36 square feet
d). Perimeter of the closet = 2(6 + 8) = 28 feet
Area of the closet = 6 × 8 = 48 square feet
e). Area of the hallway = Total area of the floor plan - area of the (kitchen + bathroom + bedroom + closet)
Area of the floor plan = 20 × 20 = 400 square feet
Area of the hallway = 400 - (92 + 96 + 36 + 48)
= 400 - 272
= 128 square feet
