Answer:
<A = 75degrees
Step-by-step explanation:
From the triangle given;
arcDA + arc AD + arcBD = 360 degrees
131 + 79 + arcBD = 360
210 + arcBD = 360
arcBD = 360 -210
arcBD = 150 degrees
Since the angle at the vertex <A is half that at the arc BD, hence;
<A = 1/2 arcBD
<A = 1/2 * 150
<A = 75degrees
Hence the measure of angle A s 75degrees

write an equation for this line
Answer:
y + 3 = 2(x - 4)
Step-by-step explanation:
Use the equation of a line format y - k = m(x - h), where m is the given slope and (h, k) is the given point. Here (h, k) is (4, -3) and m is 2.
Then y + 3 = 2(x - 4) (point-slope form)

NEED HELP ASAP!! WILL GIVE BRAINLIEST! Find the perimeter and area for the triangle. Be sure to write the formula, and use correct measure.
Answer:
Area = 77ft²
Perimeter = 44 9/20 feets
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Base = 19 1/4 feets = 77/4 feets
Height = 8 feets
Area = 1/2 * 77/4 * 8
Area = (77 * 8) / 8
Area = 77 feet²
Perimeter of a triangle :
Sum of the sides
Perimeter = a + b + c
Perimeter = 19 1/4 + 10 + 15 1/5
Perimeter = 44 + (1/4 + 1/5)
Perimeter = 44 9/20

The price of a ring varies jointly with
the cube root of no. of diamonds and
weights of gold used in it, the price
of the king was 10000, when it has
64 diamonds 15gm. of gold
find the no. of diamonds if the price of
ring was 10500 weight of gold was
21 gm. ?
Answer:
d = 27
Step-by-step explanation:
Let price = p
Number of diamonds = d
Weigh of gold = w
Hence,
P α d^1/3w
P = kd^1/3 * w
k = proportionality constant
P = 10000 ; d = 64 ; w = 15
We can obtain the value of k
10000 = k * 64^1/3 * 15
10000 = k * 4 * 15
10000 = 60k
k = 10000 / 60
Hence,
P = (10000/60)*d^(1/3)*g
To find the number of d ; when P = 10500 ; g = 21
10500 = (10000/60)*d^1/3 * 21
10500 = 3500 * d^1/3
10500 / 3500 = d^1/3
3 = d^1/3
3³ = d
27 = d
What is the magnitude of 8 and -8?
9514 1404 393
Answer:
8 and 8
Step-by-step explanation:
The magnitude of a number is the positive distance it is from the origin. The number 8 is 8 units from the origin (in the + direction). The number -8 is also 8 units from the origin (in the - direction).
Both 8 and -8 have a magnitude of 8 units.

Answer:
[tex]y=4(3)^x[/tex]
Step-by-step explanation:
From the table given in the question,
x y Difference Ratio
1 12 - -
2 36 36-12 = 24 [tex]\frac{36}{12}=3[/tex]
3 108 108-36 = 72 [tex]\frac{108}{36}=3[/tex]
4 324 324-108 = 216 [tex]\frac{324}{108}=3[/tex]
5 972 972-324 = 648 [tex]\frac{648}{216}=3[/tex]
There is a common ratio of 3 in each successive term.
Therefore, data given in the table will represent an exponential function.
[tex]y=a(b)^x[/tex]
For a point [tex](1, 12),[/tex]
[tex]12=a(b)^1[/tex]
[tex]ab=12[/tex] ------(1)
For another point of the table [tex](2,36)[/tex],
[tex]36=a(b)^2[/tex]
[tex]ab^2=36[/tex] --------(2)
Equation (2) divided by equation (1)
[tex]\frac{ab^2}{ab}=\frac{36}{12}[/tex]
[tex]b=3[/tex]
From equation (1),
[tex]3a=12[/tex]
[tex]a=4[/tex]
Therefore, exponential function will be,
[tex]y=4(3)^x[/tex]

We are given:
The function: y = -16t² + 64
where y is the height from ground, t seconds after falling
Part A:
when the droplet would hit the ground, it's height from the ground will be 0
replacing that in the given function:
0 = -16t² + 64
16t² = 64 [adding 16t² on both sides]
t² = 4 [dividing both sides by 16]
t = 2 seconds [taking square root of both sides]
Part B:
for second droplet,
height from ground = 16 feet
time taken = t seconds
acceleration due to gravity = 10 m/s²
initial velocity = 0 m/s
h = ut + (1/2)at² [second equation of motion]
16 = (0)(t) + (1/2)(10)(t²)
16 = 5t²
t² = 16/5
t = 1.8 seconds (approx)
Therefore, the second droplet takes the least amount time to hit the ground
25. Leena and Ricky went for jogging in the morning. Leena ran 2/3 of the track and Ricky ran 5/6 of
the same track. Who ran more and by how much?
Answer:
Ricky ran 16.66% more of the track than Leena
Step-by-step explanation:
First, we find how much each ran as a percentage.
Leena ran 2/3 of the track
As a percentage, Leena ran:
2*100%/3 = 66.67%.
Ricky ran 5/6 of the same track.
As a percentage, Ricky ran:
5*100%/6 = 8333%
Thus Rick ran more, by 83.33% - 66.67% = 16.66%.

In 2015, there were roughly 1x10^6 high school football players and 2x10^3 professional football players in the United States.
About how many times more high school football players were there?
Answer:
500.
Step-by-step explanation:
(1 * 10^6) / (2 * 10^3)
= 1/2 * 10^6/10^3
= 0.5 * 10^3
= 5 * 10^2
= 500.
There are 500 times high school football players more than professional football players such that there are [tex]1\times10^6[/tex] high school football players and [tex]2\times10^3[/tex] professional football players in the year of 2015.
Scientific NotationScientific notation is used to denote a large number in the form of a power of 10. We need to divide the number of high school football players and the number of professional football players to get the ratio.
How to determine the ratio between two numbers?The number of high school football players [tex]=1\times10^6[/tex].
The number of professional football players [tex]2\times10^3[/tex].
So, the ratio of high school football players to professional football players is,
[tex]\Rightarrow\dfrac{1\times10^6}{2\times10^3}\\\Rightarrow0.5\times10^3\\\Rightarrow5\times10^2\\\Rightarrow500[/tex]
Thus, there are 500 times high school football players more than professional football players.

A tray contains 16 chocolate chip cookies and 12 oatmeal raisin cookies. HOw many ways can a child select 3 cookies that include at least 1 chocolate chip cookie
Answer:
Number of ways chosen cookies = 8 ways
Step-by-step explanation:
Given;
Total number of chocolate chip cookies = 16
Total number of oatmeal raisin cookies = 12
Total number of cookies choose = 3
At least 1 chocolate cookie
Find:
Number of ways chosen cookies
Computation;
Number of total ways = 2³
Number of total ways = 8
If at least on cookie is chocolate cookie,
Number of ways chosen cookies = Number of total ways - 1
Number of ways chosen cookies = 9 - 1
Number of ways chosen cookies = 8 ways
