Which equation represents a circle with a center at (2, -7) and a radius of
4 units?
Answer:
(x-2)²+ (y+7)²=16
The equation that represents the circle is (x - 2)² + (y + 7)² = 16 with a center at (2, -7) and a radius of 4 units
The equation that represents a circle with a center at (2, -7) and a radius of 4 units can be written in the standard form as:
(x - h)² + (y - k)² = r²
where (h, k) represents the coordinates of the center and r represents the radius.
Plugging in the given values:
(x - 2)² + (y - (-7))² = 4²
Simplifying further:
(x - 2)² + (y + 7)² = 16
Therefore, the equation that represents the circle is (x - 2)² + (y + 7)² = 16.

38% of what number is 57?
38 percent of 150 is 57 so the number is 150.
We have,
Let the number be M
From the given condition make an expression to find the number.
38% of M = 57
38/100 x M = 57
Multiply 100/38 on both sides.
M = 57 x 100 / 38
Simplify the numbers.
M = 5700/38
M = 150
Cross-checked to see whether the number is true or not.
38% of 150
38/100 x 150
38/10 x 15
38/2 x 3
19 x 3
57
This is true.
Thus,
38 percent of 150 is 57 so the number is 150.

2.5d + 9.75 = 1 + 4.25d
Answer:
d = 5
Step-by-step explanation:
1.Combine multiplied terms into a single fraction
2.5d + 9.75 = 1 + 4.25d
5d/2+9.75 = 1+4.25d
2.Combine multiplied terms into a single fraction
5d/2 + 9.75 = 1 + 4.25d
5d/2 + 9.75 = 1 + 17d / 4
3.Subtract 9.75 from both sides of the equation
5d/2+9.75 = 1 + 17d/4
5d/2 +9.75 - 9.75 = 1 + 17d/ 4 - 9.75
4.Simplify
Subtract the numbers

a. ABE:
b. BEC:
c. DEF:
d. CDF:
Answer:
a. Right triangle
b. Isosceles
c. Equilateral
d. Scalene
Step-by-step explanation:
a. ∆ABE has a right angle and 3 unequal sides, so therefore it can be classified as a right triangle.
b. In ∆BEC, side BE = 7
Side CE = FE + FC = 5 + 2 = 7
This means that ∆BEC has tow equal sides. Therefore, ∆BEC is classified as an isosceles triangle.
c. ∆DEF has 3 equal sides. Therefore it is classified as an equilateral triangle.
d. ∆CDF has 3 unequal sides. Therefore, it is a scalene triangle.

An bakery chef wants to construct a pie graph to represent types of pies sold in November. He sold 700 pies, 350 of which were pumpkin ples The pumpkin ples represent how many degrees in the circle?
Answer:
[tex]180^{\circ}[/tex]
Step-by-step explanation:
Given that,
Total pies that sold = 700
Pumpkin pies = 350
We need to represent the degrees in the circle. It can be calculated as follows :
[tex]x=\dfrac{350}{700}\times 360\\\\x=180^{\circ}[/tex]
So, the pumpkin pies are represented by [tex]180^{\circ}[/tex].

Answer:
52 = 2(16 +w)width = 10 inchesStep-by-step explanation:
The perimeter formula can be used.
P = 2(L +W)
Filling in the given values, we obtain an equation that can be solved for width:
52 = 2(16 +W)
26 = 16 +W . . . . divide by 2
10 = W . . . . . . . . subtract 16
The width of the frame is 10 inches.
