Kassie and Luke timed each other during swimming practice. The speed at which swims is represented by the equation d = 1. 22t, where d is the number of meters she swims in t seconds. The speed at which Luke swims is represented in the table.
This means that a graph of Kassie speed given by the function d = 1.22t would have a slope of 1.22 m/s.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let d represent the number of meters she swims in t seconds. Hence:
d = 1.22t
This means that a graph of Kassie speed would have a slope of 1.22 m/s.

Dahlia runs a fruit store. She started Monday with 22 cherries in stock. During the day, she sold 19 cherries and got a shipment of fresh cherries. The shipment contained 3 times as many cherries as she started the day with. How many cherries does Dahlia have in stock at the end of the day?
The amount of cherrries that Dahlia has in stock at the end of the day is 69.
How many cherries does Dahlia have in stock at the end of the day?The first step is to determine the number of cherries that were remaining after 19 were sold.
Cherries remaining = 22 - 19 = 3
Number of cherries in the shipment == 22 x 3 = 66
Total number of cherries at the end of the day = 66 + 3 = 69

A state seal, which is round, hangs in the capitol building. It has a radius of 3 feet. What is the seal's area? Use 3.14 for .
Step-by-step explanation:
just apply the formula you can find immediately on the internet.
that is much faster than putting such a calculation question in here.
the area of a circle is
pi×r²
with r being the radius.
so, in our case we have
pi × 3² = pi × 9 = 28.27433388... ft²
when using 3.14 for pi we get 28.26 ft²

You are shopping and see an item that is normally priced for $950 on sale for 20% off. However, you have a coupon for an additional 30% off. (The cashier will apply your coupon to the sale price, not the normal price.)
What is the final cost of the time (before sales tax) after the sale and coupon discounts?
Answer:
The final cost before sales tax is $475.
Step-by-step explanation:
you add the 30% to the 20% and that equals 50% off. Which is half off so you have to divide $950 by 2. That equals $475. Easy :)

What is the value of this expression?
27+4×(8−4)
Answer:
43
Step-by-step explanation:
First, you have to find the value inside the parentheses. That would be 8-4, which is 4.
Now, use the rule of Pedmas, or Bedmas, whatever you prefer. That is Parentheses, exponents, multiplication, addition, subtraction. So, now you have the equation:
27 + 4 x 4.
You would multiply before addition, as shown above, so you would get:

If you invest $8,600 at a 3.95% simple annual interest rate, approximately how long will it take for you to have a total of $21,000? a. 25.3 years b. 36.5 years c. 45.9 years d. 60.7 years
The time taken to have a total of $21,000 is 36.5 years.
To calculate the time it takes to reach $21,000 with a simple annual interest rate, we can use the formula for simple interest:
Interest = Principal × Rate × Time
Where:
Interest is the additional amount earned on the initial investment (in this case, the difference between $21,000 and $8,600),
Principal is the initial investment ($8,600),
Rate is the annual interest rate (3.95% expressed as 0.0395),
and Time is the unknown variable we want to find.
We can rearrange the formula to solve for Time:
Time = Interest / (Principal × Rate)
Let's plug in the values:
Interest = $21,000 - $8,600 = $12,400
Principal = $8,600
Rate = 0.0395
Time = $12,400 / ($8,600 × 0.0395) ≈ 36.5
So, it will take approximately 36.5 years to have a total of $21,000.

By using properties for exponents, we will see that the equivalent expression is:
[tex]2x^{-4}y^6[/tex]
Which is the equivalent expression?Here you need to remember the property:
[tex]a^n/a^m = a^{n - m}[/tex]
We have the expression:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}}[/tex]
We can separate the fraction to:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}}[/tex]
Now we can simplify by using the above relation, we will get:
[tex]\frac{-4x^{-3}y^4}{-2xy^{-2}} = \frac{-4}{-2}*\frac{x^{-3}}{x} *\frac{y^4}{y^{-2}} = 2*x^{-3-1}*y^{4 - (2)} = 2*x^{-4}*y^6[/tex]

if x= -1 and y=2 is the solution of the simultaneous equations,
ax-by= 1
ay+bx= - 7
find the value of a and b with the proper steps
Answer:
a = -3, b = 1
Step-by-step explanation:
1. Plug in the given values into the equations:
a(-1) - b(2) = 1
a(2) + b(-1) = -7
2. Isolate a in the first equation:
a(-1) - b(2) = 1 = a · -1 - b · 2 = 1
-a - 2b = 1
-a -2b+2b = 1+2b
-a = 1 + 2b
[tex]\frac{-a}{-1} =\frac{1}{-1} +\frac{2b}{-1}[/tex]
a = -1 - 2b
3. Substitute "a = -1 - 2b" in for a in the second equation:
(-1 - 2b)2 + b(-1) = -7
4. Simplify:
-2 - 4b + b(-1) = -7
-2 - 4b -b = -7
-2 -5b = -7
5. Isolate for b:
-2+2 - 5b = -7+2
-5b = -5
[tex]\frac{-5b}{-5} =\frac{-5}{-5}[/tex]
b = 1
6. Substitute the b value into an equation to solve for a:
a = -1 -2 · 1
a = -3 · 1
a = -3
