Circular lawn has a row of bricks around the edge the radius of the lawn is about 20 feet which is the best estimate for the area of the grass in the long use 3.14 for pie select one 125 ft 125 square ft 1250 ft 1256 square feet
Answer:
Area of the grass in the circular lawn is 1256 square feet
Step-by-step explanation:
Lawn is in the shape of circle having radius = 20 feet
Area of the circular lawn will be represented by the formula,
Area = πr² [ Here 'r' = Radius of the circular lawn]
= (3.14)(20)²
= 3.14 × 400
= 1256 square feet
Therefore, area of the grass in the circular lawn will be 1256 square feet.

Answer:
C. 48 cubic units
If you fill up the whole prism and it takes exactly 48 cubes then you did it correctly.
Step-by-step explanation:
To find the volume of a rectangular prism you have multiply the base by the height by the width.
So the volume is b*h*w = 8*2*3 = 48
C. 48 cubic units
Since 1 cube takes 1 unit that means it takes 48 cubes to fill up the whole thing.
If you fill up the whole prism and it takes exactly 48 cubes then you did it correctly.
A tree outside Ellie’s house cast of 125 foot shadow. At the same time of day, Ellie cast a 5.5 foot shadow. If Ellie is 4‘10“ tall, how tall is the tree in feet?
Answer:
The tall of the tree is about 109.85 feet
Step-by-step explanation:
- The tree and its shadow formed a right angle triangle with legs
x the tall of the tree and 125 feet the shadow of the tree
- Ellie and her shadow formed a right triangle with legs 4 feet and
10 inches the tall of Ellie and 5.5 feet the shadow of Ellie
- The two triangles are similar
- There is an equal ratio between the corresponding sides of the
similar triangles
∵ The tall of the tree is x
∵ The tall of Ellie is 4 feet and 10 inches
babyface17
∴ The tall of Ellie is 4 feet and 5/6 foot = 4 + 5/6 = 29/6 feet
∵ The shadow of the tree is 125 feet
∵ The shadow of Ellie is 5.5 feet
- By using similarity ratio
∴ Tall of tree/tall of Ellie = shadow of tree/shadow of Ellie
∴ x/(29/6) = 125/5.5 ⇒ using cross multiplication
∴ 5.5(x) = 125(29/6) ⇒ divide both sides by 5.5
∴ x ≅ 109.85 feet
* The tall of the tree is about 109.85 feet
Answer:
109.85 ft
Step-by-step explanation:
5.5'/ 4'10"=125 ft/x
5.5*12/(4*12+10)=125/x
66/58=125/x
x=125*58/66
x=109.85 ft
A kayaker is paddling at a steady rate for 10 miles with the river current. She can only travel 4 miles against the current in the same amount of time. If the rate of the current is 8 miles per hour, what is the kayaker’s rate in still water (without the current)?
Answer: 18.66 miles per hour.
Step-by-step explanation:
The velocity of the Kayak can be written as the velocity of the kayak in still water plus the rate of the current.
If K is the velocity of the kajak, and C the velocity of the current, we have that:
When the kajak moves along with the current, for a given time T.
(K + C)*T = 10mi
when the kajak move against the current:
(K - C)*T = 4mi
now we can replace C by 8mph, and take the quotient of both equations:
((K + 8mph)*T)/(K - 8mph)*T)) = 10mi/4mi
(K + 8)/(K-8) = 10/4
K + 8 = (K- 8)*10/4
K + 8 = K*10/4 - 20
K*10/4 - K = K*6/4 = 20 + 8 = 28
K = 28*4/6 = 18.66
So the rate of the kajak is 18.66 miles per hour.

What is the measure of DAB ?
Answer: I think it might be the angle in between D and B
Step-by-step explanation: My Explanation to this is:All triangles add to 180° so...Add all the angles in the triangle.
Find the amount missing to make an overall of 180 degrees.
85+33=118 degrees
We are currently missing angle which is 62 degrees.
How ever to find the second missing angle you will need this angle (62) specifically.
because it is on a straight line, take 62 away from 180 to get 118 degrees
the answer is 118 degrees hopefully this helped you
Answer:
Step-by-step explanation:
Exterior angle equals the sum of opposite interior angles
∠DAB = ∠ABC + ∠ACB
= 85 + 33
∠DAB = 118°
Triangle G F H is rotated to form triangle G prime F prime H prime. Which type of transformation maps triangle GFH onto triangle G'F'H'? translation reflection rotation dilation
Answer:
Rotation
Step-by-step explanation:
The type of transformation maps triangle GFH onto triangle G'F'H' will be; Rotation.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs.
We are given that Triangle GFH is rotated to form triangle G prime F prime H prime.
Stretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]
Horizontal stretch by a factor k: [tex]y = f\left(\dfrac{x}{k}\right)[/tex]
The rotation transformation maps triangle GFH onto triangle G'F'H'

Calculate the lower bound for the total length of wood used to make this fence.
Write your answer in full calculator display.
200cm which has been rounded up to to the nearest cm meaning it could be 199.5cm. Then times it by 32.

Is 7 a factor of 56w - 7?
Answer:
yes it is
Step-by-step explanation:
Factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. ... The prime factors of a number or an algebraic expression are those factors that are prime.
Numbers we can multiply together to get another number.
Example: 2 and 3 are factors of 6, because 2 × 3 = 6
A number can have MANY factors!
Example: What are the factors of 12?
• 3 × 4 = 12, so 3 and 4 are factors of 12
• 2 × 6 = 12, so 2 and 6 are also factors of 12
• and 1 × 12 = 12, so 1 and 12 are factors of 12 as well
So 1, 2, 3, 4, 6 and 12 are all factors of 12
And -1, -2, -3, -4, -6 and -12 also, because multiplying negatives makes a positive.
In Algebra, factors can be expressions like "x+3" etc

What is an Angle?An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.
An angle is a figure in Plane Geometry generated by two rays or lines that share a common endpoint. The term "angle" is derived from the Latin word "angulus," which meaning "corner".
We have m < AVC = 39
and, m <VCB = 23
Thus, by adding the above angle we get the whole angle AVB.
Sp. m< AVB = m <AVC + <VCB
m <AVB = 23 + 39
