can you help me with these questions
Answer:
Girls: 50
Boys: 36
A) 60°
Step-by-step explanation:
86-14=72
72÷2=36
Girls=36+14=50
Boys=36
115+115+70=300
360-300=60°
Answer:
36 boys and 50 girls
the remaining angle measures 60°
Step-by-step explanation:
x = boy count
x + 14 = girl
x + x + 14 = 86
2x + 14 = 86
2x = 72
x = 36
x + 14 = 50
36 boys and 50 girls
the 4 angles of a quadrilateral = 360°
115° + 115° + 70° + x = 360°
300 + x = 360°
x = 360 - 300
x = 60°
The remaining angle measures 60°
The equation of the circle having center (5, 4) and touching y-axis is
A. x 2 + y2 – 10x – 8y + 25 = 0
B. x 2 + y2 – 5x + 4y + 8 = 0
C. x 2 + y2 – 5x + 4y + 8 = 0
D. x 2 + y2 – 42 – 5y + 10 = 0
Answer:
None Of the Above.
Step-by-step explanation:
As we know that the general equation of circle is
( x - h )^2 + ( y - k )^2 = r^2
putting h=5 and k= 4 and r= 5
x² + 25 - 10x + y² +16 - 8y = 25
x² + y² - 10x - 8y + 16 = 0 is the answer.

a) f'x means you find the derivative.
2 * d/dx x^2 -b * d/dx x + d/dx c
use power rule x^2 = 2x^1
2*2x = 4x. the derivative of the differentiation variable, x is 1 and the derivative of a constant, c is 0
4x-b+0
4x-b is our derivative
(I am still figuring out b and c, I will edit this answer and put the solution for b and c.)

Use 3.14 to approximate .
A = ar2
14 ft
A = [ ? ] ft?
Answer:
A =153.86 ft^2
Step-by-step explanation:
First we need to find the radius
f = d/2 = 14/2 = 7
A = pi r^2
A = 3.14 ( 7)^2
A = 3.14 * 49
A =153.86 ft^2

In △FGH, L is the centroid. If LK = 19, find GL
Answer:
GL = 38
Step-by-step explanation:
On each median the distance from the vertex to the centroid is twice as long as the distance from the centroid to the midpoint, that is
GL = 2 LK = 2 × 19 = 38
Answer:
the centroid has special featuresfor this
Step-by-step explanation:
the rate of long must be like this [GL]=2[LK]
we can say that our answer is 38 easily

Mr Li is four times as old as his son. In five years time, the sum of their ages will be 60 years. How old are they now?
Answer:
Mr Li is now 40 years old
his son is now 10 years old
Step-by-step explanation:
x = age Li
y = age son
x = 4y
x+5 + y+5 = 60
x + y + 10 = 60
x + y = 50
4y + y = 50
5y = 50
y = 10
x = 4y = 4×10 = 40
joey is going shopping for a new pair of sneakers. He finds a pair that have an original price of $155. They are on sale today for 30% off. How much does Joey pay for the sneakers including 8% sales tax?
Answer:, Joey will pay $117.18 for sneakers.
Step-by-step explanation:
Given: original price = $155
Discount rate = 30%
Tax rate = 8%
Price after discount = Original price - (Discount) x (original price)
[tex]= 155-0.30\times 155\\\\=155-46.5\\\\=\$\ 108.5[/tex]
Tax = Tax rate x (Price after discount)
[tex]= 0.08 \times 108.5[/tex]
= $ 8.68
Final price for sneakers = Price after discount + Tax
= $ (108.5+8.68)
= $ 117.18

Is triangle XYZ = ABC ? If so, name the postulate that applies. A. Congruent - ASA B. Congruent - SAS C. Might not be congruent D. Congruent - SSS
Answer:
Option D
Step-by-step explanation:
If two triangles are said to be congruent then they have exactly the same three sides and the same three angles.
Since the option D indicates that all the three sides are equal (represented as SSS), Hence, it is the right answer
Answer:
congruent SAS

Anyone know the answer?
Answer:
565.6854249 without rounds
Answer:
Step-by-step explanation:
Well, the area is 400m^2 so we know each side is 20 feet long. Then with that we can make a 40deg 40deg 90deg triangle with the side lengths 20, 20, and x. So, the proportion would be 20/1=x/rad2. This gives us x=28.28, so the fence is 28.28m long. Hope this helps :))
What is the approximate area of a circle with a radius of 6 m?
O A. 28.3 m2
O B. 18.8 m2
O c. 113 m2
O D. 38 m2
ID
Answer:
c. 113 m^2
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
Using 3.14 as an approximation for pi
A = 3.14 ( 6)^2
A = 3.14 *36
A =113.04

Answer:
f(4.7) = 13.1
Step-by-step explanation:
essentially this is just 3x-1
plug in 4.7 for x... 3*4.7 = 14.1 then subtract 1 =
13.1
the issue is the || absolute value...
if the "X" x value is NEGATIVE in the problem, just remove the negative sign...
in other words f(-4.7) = 3(4.7) - 1
Answer:
13.1
Step-by-step explanation:
f(x) = 3|x|- 1, x= 4.7
f(4.7) = 3|4.7|- 1 *replace x with 4.7
= 14.1 - 1. *multiply 3 x 4.7
= 13.1. *subtract 1 from. 14.1
