Answer:
Area of the flower garden = 31.75 square meters
Step-by-step explanation:
Circumference of the circle shaped flower garden = 20 meters
Now, The circumference of circle = 2π × radius
⇒ 2π × radius = 20
⇒ π × radius = 10
⇒ radius = 3.18 meters
Area of the flower garden = π × radius²
⇒ Area of the flower garden = 3.14 × 3.18²
⇒ Area of the flower garden = 31.75 square meters
Area of garden is 314 square feet
Area based questions:Given that;
Diameter of garden = 20 feet
Find:
Area of garden
Computation:
Radius of garden = 20/2 feet
Radius of garden = 10 feet
Area of circle = Area of garden
Area of garden = πr²
Area of garden = (3.14)(10)²
Area of garden = (3.14)(100)
Area of garden = 314 square feet

In the triangle above, the console of p degrees is 0.8 what is the sine of q degrees
Answer:
Step-by-step explanation:
[tex]cosp=(8/10)\\ \\ p=cos^{-1}(8/10)\\ \\ q=90-p\\ \\ q=90-cos^{-1}(8/10)\\ \\ sinq=sin(90-cos^{-1}(8/10)\\ \\ sinq=(8/10)[/tex]
In the triangle above, the console of p degrees is 0.8. So, the sine of angle q is 0.6.
It seems like there is a description of a triangle with angles p and q, where the console of angle p is 0.8. However, the term "console" is not familiar in the context of trigonometry. I assume you meant "cosine" instead of "console."
If that's the case, let's proceed with the assumption that cos(p) = 0.8.
The cosine of an angle is the ratio of the adjacent side to the hypotenuse in a right-angled triangle. To find the sine of angle q, we need to use the Pythagorean trigonometric identity:
sin²(q) + cos²(q) = 1
We already know that cos(p) = 0.8, and since the sum of angles in a triangle is 180 degrees, we can find q:
q = 180 - p
Now, let's calculate sin(q):
sin²(q) + cos²(q) = 1
sin²(q) + (0.8)² = 1
sin²(q) = 1 - 0.64
sin²(q) = 0.36
Now, take the square root of both sides to find sin(q):
sin(q) = √0.36
sin(q) = 0.6
So, the sine of angle q is 0.6.

Walt's haircut costs $32. He leaves a 15% tip. How much does he pay for the haircut, including the tip?
Answer:
Walt pays $47
Step-by-step explanation:
If Walt pays $32 for his haircut, and 15% is his tip,
We know here that in percentages, 15% = 15/100, which equals $15
Then, you would simply do 32 + 15
32 + 15 = 47.
Walt pays $47 for his haircut
hope this helps! <3
Answer: 36.8

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?
Answer: 5 hours
Step-by-step explanation:
If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.
It takes 5 hours to eliminate half of the caffeine from one's body.
Given that, a cup of coffee contains 140 mg of caffeine.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, 10% of 140
=0.1×140=14 mg
If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.
Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

Answer:
What is the measure of angle D?
52o
Angle D = 360-128-126-54 = 52o
Step-by-step explanation: got it right on edge
Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.
What is a quadrilateral?A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.
The sum of angles in a quadrilateral is 360 degree hence;
A + B + C + D = 360 (sum of angles in a quadrilateral)
128 + 126 + 54 + D = 360
D = 360 - ( 128 + 126 + 54)

A horizontal translation is used to move quadrilateral W XYZ onto quadrilateral
W XYZ.
Use the drop-down menus to describe the horizontal translation used.
Answer:
Quadrilateral WXYZ is translated 10 units to the left
Step-by-step explanation:
Translation of Shapes in the Plane
The translation is a type of rigid transformation where all the coordinates of the vertices that form the shape are shifted by the same number of units both vertically and horizontally.
The quadrilateral WXYZ has coordinates:
W(2,-3) X(7,-3) Y(6,-7) Z(1,-7)
The quadrilateral W'X'Y'Z' has coordinates:
W'(-8,-3) X'(-3,-3) Y'(-4,-7) Z'(-9,-7)
It can be noted that all the x-coordinates of the vertices are shifted by 10 units to the left.
Answer:
Quadrilateral WXYZ is translated 10 units to the left.

Sarah has a part time job working as a line cook. She earns $56 a night plus 5% of the tips.
A- write an equation for Sarah’s total earnings, E dollars, when the tips are t dollars.
B- what will Sarah earn when the tips are $350? Explain your strategy
C- what were the nightly tips when Sarah earned $81? Explain your strategy
Thank you :]
Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05

There are 6 bookshelf's that hold 72 books per shelf. if 1/3 of the total number of books are non-fiction,how many fiction books are there.
Answer:
288 fiction books
Step-by-step explanation:
If the other 2/3 are fiction, then I believe that you would multiply 72 by 6 then divide by 3 or multiply by 1/3 giving you 144. Multiply 144 by 2 and you should get 288, but this is if there are only fiction and non fiction. Sorry if this is wrong..

Triangle TVW is dilated according to the rule
DO,(x,y)(three-fourths x, three-fourths y) to create the image triangle T'V'W', which is not shown.
On a coordinate plane, triangle T V W has points (negative 4, 8), (0, 4), and (4, 4).
What are the coordinates of the endpoints of the segment T'V'?
T'(-3, 6) and V'(0, 3)
T'(-3, 6) and V'(0, 1)
T'(-1, 2) and V'(0, 3)
T'(-1, 2) and V'(0, 1)
Answer:
D
Step-by-step explanation:
The coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]
What is dilation of triangle?Dilation of triangle means each point is stretched outwards or inwards from the center point by multiplying by the scale factor to form a similar triangle.
We have,
Triangle [tex]T V W[/tex] which has points [tex](- 4, 8)[/tex], [tex](0, 4)[/tex], and [tex](4, 4)[/tex] on a coordinate plane.
Scale factor [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex]
It has to be dilated to create a new triangle [tex]T'V'W'[/tex] .
So,
To create a new triangle [tex]T'V'W'[/tex] we have to multiply the original triangle's coordinate by scale factor, to get new triangle's coordinate .
So, we have to dilate the coordinates by [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex] ,
[tex]T'=(- 4, 8)=\frac{3}{4} *(-)4, \frac{3}{4} *8= (-3,6)[/tex]
[tex]V'=(0, 4)=\frac{3}{4} *0, \frac{3}{4} *4=(0,1)[/tex]
[tex]W'=(4, 4)=\frac{3}{4} *4,\frac{3}{4} *4=(0,0)[/tex]
So, the coordinates of triangle [tex]T'V'W'[/tex] after dilation are [tex](-3,6), \ (0,1), \ (0,0)[/tex] . Hence we can say that the coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]
