Answer:
Diameter of the circle = 5.0 unit
The length of the chain = 40 units
Step-by-step explanation:
Given
Number of thin gold circles used for making bracelet is equal to 8
Radius of the circle = 2.5 units
Diameter of the circle = 2 * Radius of the circle
Diameter of the circle = 2 * 2.5 = 5.0 unit
The length of the chain = 8 * diameter = 8 * 5 = 40 units
Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.
Answer:
y = -2(x + 3)^2 - 1
Step-by-step explanation:
The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.
Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:
-1 = a(-4 + 3)^2 - 1, which must be solved for a:
-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:
y = -2(x + 3)^2 - 1
Two bottles and their labels are mathematically similar.
The smaller bottle contains 0.512 litres of water and has a label with area 96 cm².
The larger bottle contains 1 litre of water.
Calculate the area of the larger label.
Answer:
The area of the larger label is 187.5 square centimeters.
Step-by-step explanation:
If the two bottles are mathematically similar, then the label area is directly proportional to the capacity of the bottle. If we know that a 0.512 L-bottle has a label area of 96 square centimeters, then the label area of a 1-L bottle is determined by this simple rule of three:
[tex]x = 96\,cm^{2}\times \frac{1\,L}{0.512\,L}[/tex]
[tex]x = 187.5\,cm^{2}[/tex]
The area of the larger label is 187.5 square centimeters.

subtract 7
x = 28
I need this answer as soon as possible will give brain thing
Answer: X=5 so whats 3 + 5? easy, 8. so now you know the bottom is eight and since it's a rectangle the top is also 8. And the left side is 15 so we know the right side is also 15. To find the perimeter you add all the sides of which in this case it would be 8 + 8 + 15 + 15. or (8 times 2) + (15 times 2). = 46 the answer is 46

Find the value of x.
Answer:
x = 30°
Step-by-step explanation:
< A = 90° {Being vertically opposite angles }
Now
x + 90° + 2x = 180° (Being linear pair)
3x = 180° - 90°
3x = 90°
x = 90° / 3
x = 30°

Can you help me match each figure with the appropriate angle pair relationship
Answer:
co interior angle plz take my and
Answer:
1) Alternate exterior
2) alternate interior
3) consecutive interior angles
Alright so here’s a trick
Alternate already means different sides so look for that.
Interior angles are all the angles inside the two parllel lines.
Exterior angles are all angles out side the two parralel lines.
No matter what if its alternative interior or exterior, it should make a perfect
“/“ or back slash.
Consecutive is on the same side.
Corresponing is also on the same side but it has 1 exterior and 1 interior

Answer:
B) 12.6π ; 39.6
Step-by-step explanation:
Circumference:
C = 2πr
C = 2(3.14)(6.3)
C = 6.28(6.3)
C = 39.6
C = 2πr
C = 2π6.3
C = 12.6π

Step-by-step explanation:you have to find the height of the triangle first which is easy bc it’s been split in half so the are now two right triangles. use the pythagorean theorem to determine the height, the height is 12, the formula for the area of a triangle is 1/2bxa and half of the base is already given to you, 5 so 5 x 12 equals 60

A swimming pool is in the shape of a rectangular prism with a horizontal cross-section 10 feet by 20 feet. The pool is 5 feet deep and filled to
capacity. Water has a density of approximately 60 pounds per cubic foot, or 8 pounds per gallon.
What is the approximate weight of water in the pool?
Answer:
The weight of the water in the pool is approximately 60,000 lb·f
Step-by-step explanation:
The details of the swimming pool are;
The dimensions of the rectangular cross-section of the swimming pool = 10 feet × 20 feet
The depth of the pool = 5 feet
The density of the water in the pool = 60 pounds per cubic foot
From the question, we have;
The weight of the water in Pound force = W = The volume of water in the pool given in ft.³ × The density of water in the pool given in lb/ft.³ × Acceleration due to gravity, g
The volume of water in the pool = Cross-sectional area × Depth
∴ The volume of water in the pool = 10 ft. × 20 ft. × 5 ft. = 1,000 ft.³
Acceleration due to gravity, g ≈ 32.09 ft./s²
∴ W = 1,000 ft.³ × 60 lb/ft.³ × 32.09 ft./s² = 266,196.089 N
266,196.089 N ≈ 60,000 lb·f
The weight of the water in the pool ≈ 60,000 lb·f
Cole bought 10 gallons of gas at the gas station with the lowest price. He paid with two $20 bills. Write and solve an equation to find his change.
Answer:
$4.3
Step-by-step explanation:
Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.
two $20 bills = 2 * $20
= $40
Gallons of gas = 10
Lowest price of each gallon = $3.57
Cost of 10 gallons of gas = 10 * $3.57
= $35.7
Let his change = x
His change = Amount paid with - cost of gas
x = $40 - $35.7
x = $4.3
His change = $4.3

What is the slope, m, of the line through (-9, -17) and (-9, 12)?
Express the slope as a fraction in lowest terms.
If the slope is undefined, enter undefined into the text box.
m =
Answer:
m = undefined
Step-by-step explanation:
(-9, -17) and (-9, 12)
Slope:
m=(y2-y1)/(x2-x1)
m=(12+17)/(-9+9)
m=29/0
Since 0 is the denominator, the slope is undefined
