Step-by-step explanation:
How much greater is the distance between buoys A and B than the distance between
buoys B and C?
Answer:
4
Step-by-step explanation:
1. the distance between A and B can be calculated:
[tex]|AB|=\sqrt{(4+4)^2+(-4-2)^2} =10.[/tex]
2. the distance between B and C can be calculated:
[tex]|BC|=\sqrt{(-4+4)^2+(2+4)^2} =6.[/tex]
3. if AB=10, BC=6, then difference between them is 4.
Solve for a.
4/a+4 =-1/a+9
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8
Review: Jen sells flowers. She charges $2 per flower plug a $3 flat delivery fee. How much will she make if she has to deliver 6 flowers?
Answer:
$30
Step-by-step explanation:
Answer:
$15 dollars
Step-by-step explanation:
We know that Jen sells flowers. We also know that she charges $2 dollar per flower plus a $3 dollar delivery fee.
The question is asking how much will Jen make if she sells 6 flowers. Since every flower costs 2 dollars, we can multiply the cost and amount.
6 * 2
12.
Jen makes 12 dollars just by the flower, and now the delivery fee which is an extra 3 dollars.
12 + 3
$15

Andre has a puppy that weighs 9 pounds the vet says the puppy is now at 30% of its adult weight what will the adult weight of Andres puppy be
The adult weight of the puppy of Andre puppy be 30 pounds.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Andre has a puppy that weighs 9 pounds.
The vet says the puppy is now at 30% of its adult weight.
Let n pounds be the weight of an adult.
Using the percentage formula,
9 = 30 x n /100
n = 900/30
n = 30 pounds
Therefore, adult puppy weight is 30 pounds.

Answer/Step-by-step explanation:
A1. Reference angle = 41°
Hypotenuse = x
Adjacent = 7
Thus, applying trigonometric ratio, we would have:
Cos 41 = 7/x
Multiply both sides by x
x × cos 41 = 7
Divide both sides by cos 41
x = 7/cos 41
x = 9.3 (nearest tenth)
A2. Reference angle = 65°
Hypotenuse = 6
Opposite = y
Thus, applying trigonometric ratio, we would have:
Sin 65 = y/6
Multiply both sides by 6
6 × sin 65 = y
5.4 = y (nearest tenth)
y = 5.4
A3. Reference angle = 50°
Hypotenuse = z
Opposite = 8
Thus, applying trigonometric ratio, we would have:
Sin 50 = 8/z
Multiply both sides by z
z × sin 50 = 8
Divide both sides by sin 50
z = 8/sin 50
z = 10.4 (nearest tenth)
B1. Reference angle = 49°
Hypotenuse = x
Opposite = 7
Thus, applying trigonometric ratio, we would have:
Sin 49 = 7/x
Multiply both sides by x
x × sin 49 = 7
Divide both sides by sin 49
x = 7/sin 49
x = 9.3 (nearest tenth)
B2. Reference angle = 25°
Hypotenuse = 6
Adjacent = y
Thus, applying trigonometric ratio, we would have:
Cos 25 = y/6
Multiply both sides by 6
6 × cos 25 = y
y = 5.4 (nearest tenth)
B3. Reference angle = 40°
Hypotenuse = z
Adjacent = 8
Thus, applying trigonometric ratio, we would have:
Cos 40 = 8/z
Multiply both sides by z
z × cos 40 = 8
Divide both sides by cos 40
z = 8/cos 40
z = 10.4 (nearest tenth)
the width of a rectangle is 1/4 it’s length. the perimeter of the rectangle is 600ft. what is the length, in feet, of the rectangle?
Answer:
let length be l and breadth 1/4×l
perimeter of the rectangle =600ft
2(l+1/4×l)=600ft
(4l+l)/4=600/2
5l=300×4
l=1200/5=240ft
Step-by-step explanation:
240ft is the length of a rectangular.

What is the height of a triangle, if the area is 20 square inches and the base is 5 inches? Be sure that you can explain how you found your answer.
so normally we would be finding the area of a triangle which is a=h*b/2
but in this case we are finding the height so theirs 3 ways to do this but i prefer the basic way
20=1/2(5)h
20=2.5
8=h
and to find out if that was correct lets do 8*5=40 40/ 2 =20 so this is correct
the height is 8

Help! Plz tap on photo I will give u 10 points
50 POINTS PLEASE HELP! Write g (x)=2f (x) as a piecewise function f (x) is defined as follows:
SEE PICTURE
Step-by-step explanation:
Since g(x) = 2f(x), we apply scalling parallel to the y-axis by a factor of 2 onto f(x).
For x + 6 if x < 2,
It becomes 2(x + 6) if x < 2.
We have 2x + 12 if x < 2.
For x² + 4x - 15 if 2 <= x <= 5,
It becomes 2(x² + 4x - 15) if 2 <= x <= 5.
We have 2x² + 8x - 30 if 2 <= x <= 5.
For 5 - x if 5 < x,
It becomes 2(5 - x) if 5 < x.
We have 10 - 2x is 5 < x.
The answer is the 1st option.
