Answer:
8.6
Step-by-step explanation:
Use the law of cosines
[tex]d^{2} = e^{2} + f^{2} -2ef cos D[/tex]

Step-by-step explanation:
a^2 + b^2 = c^2
60^2 + a^2 = 75^2
3,600 + a^2 = 5,625
- 3,600 - 3,600

Find the area of the shaded region. Round your answer to the nearest hundredth.
Two concentric circles such that the inner circle divides the radius of outer circle into two segments of equal lengths labeled 8 centimeters. The region formed between two circles and one diameter of outer circle is shaded. The diameter makes an arc that measures 180 degrees.
The area is about ??? square centimeters. (if you have another answer you can add me on discord ^LoneLai^#0320)
Answer:
FIRSTLY GET THE AREA OF THE WHOLE CIRCLE BY USING FORMULA [tex]pi \times r ^2[/tex]THEN AFTER THAT DIVIDE THE AREA BY 2AFTER THAT UR ANSWER WILL COMEPLEASE MARK ME AS BRAINLIEST
Thus the area of shaded region is 301.5 cm^2.
What is circle?"The collection of all points equidistant from a fixed point in a plane is called a circle".
For the given situation,
The radius of the inner circle be r = 8 cm and
the radius of the outer circle be R = 16 cm
The formula to find area of the circle, [tex]A=\pi r^{2}[/tex]
Area of inner circle, [tex]A_{1} =\pi r^{2}[/tex]
⇒[tex]3.14[/tex] × [tex]8[/tex] × [tex]8[/tex]
⇒[tex]200.96[/tex]
≈[tex]201[/tex]
Area of outer circle, [tex]A_{2} =\pi R^{2}[/tex]
⇒[tex]3.14[/tex] × [tex]16[/tex] × [tex]16[/tex]
⇒[tex]803.84[/tex]
≈[tex]804[/tex]
The shaded region replicates the semicircle. So,
Area of the shaded region [tex]=\frac{A_{2} }{2} -\frac{A_{1} }{2}[/tex]
⇒[tex]\frac{804}{2} -\frac{201}{2}[/tex]
⇒[tex]402-100.5[/tex]
⇒[tex]301.5 cm^{2}[/tex]
Hence we can conclude that the area of shaded region is [tex]301.5 cm^{2}[/tex]

the x and y axis are tangent to a circle with radius 3 units. write a standard equation of the circle.
Given:
The x and y axis are tangent to a circle with radius 3 units.
To find:
The standard form of the circle.
Solution:
It is given that the radius of the circle is 3 units and x and y axis are tangent to the circle.
We know that the radius of the circle are perpendicular to the tangent at the point of tangency.
It means center of the circle is 3 units from the y-axis and 3 units from the x-axis. So, the center of the circle is (3,3).
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is the center of the circle and r is the radius of the circle.
Putting [tex]h=3,k=3,r=3[/tex], we get
[tex](x-3)^2+(y-3)^2=3^2[/tex]
[tex](x-3)^2+(y-3)^2=9[/tex]
Therefore, the standard form of the given circle is [tex](x-3)^2+(y-3)^2=9[/tex].

Grogg says that if you square a number then square eoot it, he will always end up with the same number he started with. Is this correct? Why or Why not?
Answer:
Yes
Step-by-step explanation:
Given a number, a
Square of number = a²
Square root of number = √a² = a
Assume a = 4
The square of 4 = 4² = 16
The square root of 16 = √16 = 4
Hence, Grogg is correct
Yanyiah has m dollars. If Erica has 2 times as many dollars as Yanyiah minus 3 dollars, write an expression for how much money Erica has.
Answer: Erica has 2m-3 dollars
Step-by-step explanation:
Amount of dollars Yanyiah has = m dollars =$m
Erica has 2 times as many dollars as Yanyiah minus 3 dollars, can be expressed as =(2m-3)dollars,
We can therefore say Erica has 2m-3 dollars.

CARL BUYS 4 ONT PINT CARTONS OF MILK. HE BUYS LESS JUICE THAN MILK. WHICH COULD BE THE AMOUNT OF JUICE.
Answer:
0 pints ≤ J ≤ 4 pints
Where J is the amount of juice that Carl bought.
Step-by-step explanation:
Here we need to learn how to use the inequality symbols.
Let's define each one of them:
A < B (A is strictly smaller than B)
A > B (A is strictly greater than B)
A ≤ B (A is smaller than or equal to B)
A ≥ B (A is greater than or equal to B)
A ≠ B (A is different than B)
Ok, in this case, we know that Carl buys 4 one-pint cartons of milk.
Then the total amount of mil that he buys is 4 times one pint, this is:
4*1 pint = 4 pints
He has 4 pints of milk.
And we know that he buys less juice than milk, then if J represents the amount of juice that he bought, we need to have:
J < 4 pints
This means that the amount of juice that he bought is smaller than the quantity of milk that he bought (4 pints)
If we want to be more correct, we should write:
0 pints ≤ J ≤ 4 pints
Here we say that J needs to be a positive number (we can't buy a negative quantity of juice)

A gardener is planning to build a flower bed with two equally-sized sections. The gardener will use a total of 36 feet of wood to surround both sections of the flower bed. The diagram shows the flower bed. create an equation to represent this situation.
Answer:
The equation representing the situation is;
36 = 3·y + 4·x
Step-by-step explanation:
The structures the gardener is planning to build = Equally-sized sections of flower bed
The length of wood the gardener has to surround both gardens = 36 feet
The perimeter of the entire garden, P = 2·y + 2 × 2·x
The length of the wood separating the two gardens = The length of the side 'y'
The perimeter of the garden and the length of the fence separating the two gardens = P + y = 2·y + 2 × 2·x + y = 3·y + 4·x
Therefore the length of wood available, 36 feet, will be used for a length equivalent to P + y
∴ 36 = P + y = 3·y + 4·x
∴ 36 = 3·y + 4·x
The equation representing the situation is 36 = 3·y + 4·x.
