Answer:
20 units
Step-by-step explanation:
31 - 7 = 24
33 - 1 = 32
24 ^2 + 32^ 2 = c^2
576 + 1024 = c^2
c = 40(diametre)
r = 40÷ 2

Brianna bought snacks for her team's practice. She bought a bag of oranges for $2.72 and a 20-pack of juice bottles. The total cost before tax was $45.12. How much was each bottle of juice?
Answer:
each bottle was $2.12 :P
Step-by-step explanation:
➼start by making an equation to find the price of the juice pack, in this case x would be the price of the juice pack because its unknown, the juice pack price(x) added to the price of the oranges(2.72) and equal the total(45.12), the before tax part is not needed info
2.72 + x = 45.12
➼now our aim to get x alone to find out its worth so we will have to do the opposite and subtract 2.72 from everything, since its positive
2.72-2.72=0 crosses out
45.12-2.72=42.4
➼which gets us x = 42.4 so one 20 pack is 42.40 dollars but we arent done yet, to find out the price of EACH bottle we must divide 42.4 by 20!
42.4/20=2.12
➼so to sum it up, each bottle is $2.12 :)
Answer:
$2.12
Step-by-step explanation:
1. Take the total and subtract the amount of the oranges so we can focus on the juice boxes.
45.12 - 2.72 = 42.4
2. Now that the oranges are out of the way, take the remaining amount of the total (how much the 20 boxes cost all together), 42.4, and divide by 20 to find how much each box costs.
42.4 ÷ 20 = 2.12

Sandra saves 13% of her salary for retirement. This year her salary was $1,000 more than in the previous year, and she saved $5,720. What was her salary in the previous year?
Complete the equation. 0.13(x + ) = 5,720
Sandra's salary in the previous year was .
Answer:
Step-by-step explanation:
Let the salary in the previous year = $ x
Now the salary = $ (x +1000)
This year savings = $ 5720
13% * (x + 1000)= 5720
0.13 *(x + 1000) = 5720
0.13*x + 0.13*1000 = 5720
0.13x + 130 = 5720 {subtract 130 from both sides}
0.13x = 5720 - 130
0.13x = 5590 {Divide both sides by 0.13}
x = 5590/0.13
x = $ 43000
Sandra's previous year salary = $ 43000

Find the distance d(A,B) between points A and B.
A(1. - 6); B(1,7)
Answer:
d = 13
Step-by-step explanation:
d = √(x2 - x1)² + (y2 - y1)²
d = √[7 - (-6)]² + (1 - 1)²
d = √(13)² + (0)²
d = √169
d = 13

Simplify (4+2i)(4-2i)
A. 20
B. 12
C. 16-4i
D. 16+4i
[tex](a+b)(a-b)=a^2-b^2\\\\(4+2i)(4-2i)=4^2-(2i)^2=\boxed{16-4i^2}[/tex]
Answer:
A
Step-by-step explanation:
We want to simplify the expression:
[tex](4 + 2i)(4- 2i)[/tex]
Notice that this is the difference of two squares. That is:
[tex](a +b)(a-b) = a^2 - b^2[/tex]
We can let a = 4 and b = 2i. Hence:
[tex](4+2i)(4-2i) = (4)^2 - (2i)^2[/tex]
Simplify:
[tex]= (16) - (4i^2) \\ \\ = 16 - (-4) \\ \\ = 20[/tex]
(Note that i² = -1.)
In conclusion, our answer is A.
Give the rate in miles per hour.
28 miles in 3/4 hour
28 miles 3/4 hour=
Answer:
37.33 mph
Step-by-step explanation:
calculator soup app is good for this type of problem.
The rate when expressed in miles per hour gives us;
37.33 miles per hour
We are given;
28 miles in 3/4 hour
This means that a distance of 28 miles is covered in every 3/4 hour.
Now, we want to express it as a rate in miles per hour
Miles per hour simply means speed.
We know that formula for speed is;
Speed = distance/time
Speed = 28 miles/(3/4 hour)
Speed = (28 × 4)/3
Speed = 37.33 miles per hour
Thus, the rate when expressed in miles per hour is 37.33 miles per hour

PLS PLS HELP SLOPE INTERCEPT FORM through: (2, 1), parallel to y=-5
Answer:
y = 1
Step-by-step explanation:
The line with equation y = - 5 is a horizontal line parallel to the x- axis.
Then a line parallel to it will also be horizontal with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (2, 1) with y- coordinate 1 , then
y = 1 ← equation of parallel line
