Multiply total by decimal.
1399 x 0.065
= 90.935
Add sum to total.
90.935 + 1399
= 1489.935
In money it would be rounded to
$1498.94

Triangle XYZ is similar to triangle RST what is the perimeter of triangle RST
The perimeter of triangle RST is B) 56.25 units. Therefore, the correct answer is B) 56.25 units.
The perimeter of a triangle is the sum of the lengths of its sides.
Since triangle XYZ is similar to triangle RST, the ratio of the corresponding sides of the two triangles is the same.
Therefore, we can set up the following proportion:
XY / XZ = RS / RT
Substituting the known values, we get:
15 / 4 = RS / RT
Multiplying both sides by RT, we get:
15 = RS * RT
We also know that the sum of the angles in a triangle is 180 degrees. Therefore, we can set up the following equation:
90 + ∠RST + ∠SRT = 180
Substituting the fact that triangle XYZ is similar to triangle RST, we get:
90 + ∠XYZ + ∠XZY = 180
Substituting the known values, we get:
90 + 30 + 60 = 180
Therefore, ∠RST = 60 degrees.
Now that we know the lengths of two sides of triangle RST and the measure of one angle, we can use the law of cosines to find the length of the third side:
RT^2 = RS^2 + ST^2 - 2 * RS * ST * cos(∠RST)
Substituting the known values, we get:
RT^2 = 15^2 + ST^2 - 2 * 15 * ST * cos(60 degrees)
Simplifying, we get:
RT^2 = 225 + ST^2 - 15ST
We also know that the perimeter of triangle RST is equal to the sum of the lengths of its sides:
Perimeter = RS + RT + ST
Substituting the fact that triangle XYZ is similar to triangle RST, we get:
Perimeter = 15 + RT + ST
Now that we know the length of RT and the fact that the perimeter of triangle RST is equal to the sum of the lengths of its sides, we can substitute these values into the equation for the perimeter to find the length of the third side, ST:
Perimeter = 15 + RT + ST
ST = Perimeter - 15 - RT
ST = 56.25 - 15 - 37.5
ST = 3.75
Therefore, the perimeter of triangle RST is:
Perimeter = RS + RT + ST
Perimeter = 15 + 37.5 + 3.75
Perimeter = 56.25
Therefore, the correct answer is B) 56.25 units.

Solve for P.
4p = 1/2
Answer:
1/8
Step-by-step explanation:
You need to find P not 4p so you divide 4p by 4 to get P and by doing this you have to divide the other side too. so now you got 4p/4 = 1/2/4 which = p=1/8

nadia has 4 sheets of stickers there are 8 stickers on each sheet .she wrote this number sentence to represent the totel number of stickers
Answer:32
Step-by-step explanation:
This question requires multiplying.
Think of 4 sheets as 4 groups. If there are 8 stickers in the first group, we still have 8, then we will add 8 to the second group. We will have 16. Next we will add 8 to third the third group, 24, and third to the fourth group which will give us 32. 8,16,24,32.
Our equation will be 8×4=32

Trampoline Park has an admission fee, plus an hourly fee of $4.50. Determine the admission fee that the trampoline park charges. What is the initial value?
The initial value of a function is when x = 0. The initial value of the Trampoline Park is $5.00
Given that:
[tex](x_1,y_1) \to (3,18.5)[/tex]
[tex]m = 4.50[/tex] ---- the rates
The equation is calculated using:
[tex]y = m(x - x_1) + y_1[/tex]
So, we have:
[tex]y = 4.50(x - 3) + 18.5[/tex]
Open bracket
[tex]y = 4.50x - 13.5 + 18.5[/tex]
[tex]y = 4.50x + 5.00[/tex]
The initial value is when [tex]x=0[/tex]
So, we have:
[tex]y = 4.50 \times 0 + 5.00[/tex]
[tex]y = 5.00[/tex]
Hence, the initial value is $5.00

What is the approximate percent decrease when a fish count goes down from 850 to 500?
Answer:
About 40%
Step-by-step explanation:
It would normally be 41.--% But rounded is the approximate percent so it would be 40%. I hope this helps you! :)
Answer: 41%

The change in fish count = [tex]850-500=350[/tex]
The percent decrease when a fish count goes down from 850 to 500 is given by :-
[tex]\text{Percent decrease}=\frac{\text{Change in fish count}}{\text{Previous fish count}}\times100\\\\\Rightarrow\text{Percent decrease}=\frac{350}{850}\times100\\\\\Rightarrow\text{Percent decrease}=41.176470588\%\approx41\%[/tex]
