Sandra notices a fourth racer called the Whirlwind. Its poster says it covers 1232 yards in 180 seconds. She wants to compare the Whirlwind with the other racers. What is the Whirlwind's speed in yards per seconds to the nearest tenth?
Answer:
6.8yards/seconds
Step-by-step explanation:
Speed = Distance/Time
Given the following
Distance covered = 1232 yards
Time taken = 180 seconds
Substitute to get the speed
Speed = 1232/180
Speed = 6.84
Hence whirlwind's speed in yards per seconds to the nearest tenth is 6.8yards/seconds
Suppose that P, is invested in a savings account where interest is compounded continuously at 6% per year.
When will the investment double itself?
Answer:
We'll need the attached equation.
We'll use as an example that principal = 100 and total =200.
Years = ln (total/principal) / rate
where "ln" means natural log
Years = ln (200/100) / .06
Years = ln (2) / .06
Years = 0.69314718056 / .06
Years = 11.5524530093

A $28.80
B $2,880.00
C $508.80
D $768.00
Answer:bellow hope I helped most likely c
Step-by-step explanation:
If 2% per year
480 x 1.02 = 489.6 first year
489.6 x 1.02= 499.392. Second year
499.392 x 1.02 = 509.37984 third year
If 2 % per all 3 years
480 x 1.02 = 489.6 all 3 years
If 2 % per each month

I have to find the missing angles
Answer:
11 & 12 = 19⁰
13 = 71⁰
14, 15, 16 & 17 = 90⁰
18 & 20 = 78⁰
19 = 12⁰
Step-by-step explanation:
14,15,16 and 17 are formed from perpendicular lines. They are not counted as angles for the kite because, the are in the middle of the kite, not at the side...
You can easily find the angles using the triangle angles formula...to find 12,
180 - 90 - 71 = 19
To find 20 & 18, with the same method,
180 - 90 - 12 = 78

Express as a trinomial.
(2x+1)(x+9)
Answer:
2x^2 + 19x + 9
Step-by-step explanation:
Using the FOIL method (ask me via comments if you don't know what it is), we expand it to 2x^2 + 18x + x + 9, then we add like terms, equal to 2x^2 + 19x + 9.
The trinomial expression for (2x + 1)(x + 9) is [tex]2x^2 + 19x + 9[/tex].
To express (2x + 1)(x + 9) as a trinomial, you need to perform the multiplication.
Distribute each term from the first parenthesis to each term in the second parenthesis:
(2x + 1)(x + 9) = 2x * x + 2x * 9 + 1 * x + 1 * 9
Now, simplify the expression:
[tex]= 2x^2 + 18x + x + 9[/tex]
Finally, combine like terms:
[tex]= 2x^2 + 19x + 9[/tex]
So, (2x + 1)(x + 9) expressed as a trinomial is [tex]2x^2 + 19x + 9.[/tex]

Kelly rides the bus to work d days each month. She pays a fare of $2.25 each time. On t of those days, she pays an additional fare of $0.75 to transfer onto another bus. The expression shown can be used to find her total cost for bus fare for the month.
d × 2.25 + t × 0.75
Which statement explains how to find Kelly’s total bus fare for the month?
Answer: A: find the product of D and $2.25 and the product of t and $0.75. Then find the sum of the two products.
The total fare for the bus can be found by first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given that,
The total fare for the bus can be calculated using the expression
d × 2.25 + t × 0.75
Here d is the total days that Kelly worked in a month.
On each of these days, she pays a fare of $2.25.
Total fare now = d × 2.25
Find this product.
There is also an additional fare of $0.75 to transfer onto another bus on t of these days.
Additional fare = t × 0.75
Find this product.
Add the resultant both products.
Hence the statement which explains how to find Kelly's total bus fare for the month is first find the product of d and $2.25 and the product of t and $0.75. Then find the sum of the products.
