Answer:
5
Step-by-step explanation:
The numerator is the value on top, above the denominator. In an arithmetic sequence you are increasing by the same amount each time. In this case, you are increasing by 1/2 each time. 4/2 plus 1/2 is 5/2, so your numerator is 5.

1,000
10,000
40,000
Answer: The answer is 10,000
Step-by-step explanation:
10^4 is equal to 10,000
10^4 to the second power means that you have too add 4 zeros to the end of the number.
Since 10 already has a 0, you would add 3 more.
Therefore, the answer would be 10,000.

Omg! Thank you. I was stuck for like an hour till I found this.
Answer:
Omg, thank you so much
Step-by-step explanation:
Find the solutions for a triangle with a = 16, c =12, and B = 63º.
a. A = 71.6°; C = 52.89; b =12.0
C. A = 68.6° C = 45.40; b=12.0
b. A = 71.6°; C = 45.40; b =15.0
d. A = 68.6°; C = 52.89; b=15.0
Answer:
b. A = 71.6°; C = 45.40°; b =15.0
Step-by-step explanation:
The missing values can be found with the help of the Law of Cosine and properties of triangles:
Side b (Law of Cosine)
[tex]b = \sqrt{a^{2}+c^{2}-2\cdot a \cdot c \cdot \cos B}[/tex]
[tex]b = \sqrt{16^{2}+12^{2}-2\cdot (16)\cdot (12) \cdot \cos 63^{\circ}}[/tex]
[tex]b \approx 15.022[/tex]
Angle A (Law of Cosine)
[tex]\cos A = -\frac{a^{2} - b^{2}-c^{2}}{2\cdot b \cdot c}[/tex]
[tex]\cos A = - \frac{16^{2}-15.022^{2}-12^{2}}{2\cdot (15.022)\cdot (12)}[/tex]
[tex]\cos A = 0.315[/tex]
[tex]A= \cos^{-1} 0.315[/tex]
[tex]A \approx 71.639^{\circ}[/tex]
Angle C (Sum of internal angles in triangles)
[tex]C = 180^{\circ} - 63^{\circ} - 71.639^{\circ}[/tex]
[tex]C = 45.361^{\circ}[/tex]
Hence, the right answer is B.

Have a nice day.
Answer:
a=-3.2
Step-by-step explanation:
Simplify the equation:
a - 1.3 =-4.5
Add 1.3 to both sides:
a -1.3 +1.3 =-4.5+1.3
a=-3.2
Find the area. Will mark brainliest.
Answer:
216
Step-by-step explanation:
I think that it is 216 because if you add 18 and 10 you get 28 then multiply 28 by 12 then you get 336. Then you will find the area of the unshaded part which is 120. Then you will subtract 120 from 336 to get 216.
Hope this helps

If PQ is tangent to circle R at point Q and PS is
tangent to ⊙R at point S, what is the perimeter
of quadrilateral PQRS?
Answer:
Perimeter of the quadrilateral PQRS is 25 units
Step-by-step explanation:
From the figure attached,
PQ is a tangent to the given circle so m∠PQR = 90°
Now we apply Pythagoras theorem in the ΔPQR,
PR² = PQ² + QR²
(PT + TR)²= PQ² + 5²
(4 + 5)² = PQ² + 25
81 = PQ² + 25
PQ = √(81 - 25)
= √56
≈ 7.5 units
PQ ≅ PS ≅ 7.5 units
[Since measures of tangents drawn from a point to a circle are always equal]
Perimeter of PQRS = PQ + QR + RS + PS
= 7.5 + 5 + 5 + 7.5
= 25 units
Therefore, perimeter of the quadrilateral PQRS is 25 units.
Answer:
10 + 4 square root 14
Step-by-step explanation:
so the person below or above me said 25 units and they are not wrong it just the did have it in a simple equation like this ^
so 4 square root 14 = 14.9 or 15
then 10 + 15 = 25 units
so the correct answer is 10 + 4 square root 14

What is the probability of rolling a die 6 times and getting the numbers 1, 2, 3, 4, 5, 6 in that order? Select the best answer from the choices provided.
A. 0.001389
B. 0.000129
C. 0.000021
D. 0.0000038
Answer:
C. 0.000021
Step-by-step explanation:
Each roll of the die is an independent event.
The probability of rolling a 1, then a 2, then a 3, then a 4, then a 5, then a 6 is the product of the 6 individual probabilities.
Probability of rolling a 1:
There are 6 possible outcomes, rolling 1, 2, 3, 4, 5, or 6.
There is one desired outcome, rolling a 1.
p(1) = 1/6
Probability of rolling a 2:
Similar to rolling a 1, there is 1 desired outcome,rolling a 2, out of 6 possible outcomes.
p(2) = 1/6
The same is true for rolling a 3, 4, 5, or 6. Each one has a probability of 1/6.
p(1, 2, 3, 4, 5, 6, in that order) = p(1) * p(2) * p(3) * p(4) * p(5) * p(6)
= (1/6)^6
= 1/6 * 1/6 * 1/6 * 1/6 * 1/6 * 1/6
= 1/46,656

A person standing on level ground is 2000 feet away from the foot of a 420-foot-tall building, as shown in the accompanying diagram. To the nearest degree, what is the value of X?
Answer:
12
Step-by-step explanation:
The formula for the tangent of an angle is the length of the opposite side divided by the length of the adjacent side. Therefore, the tangent of angle x is 420/2000=0.21. Taking the arctangent of that to get the angle, you get about 12 degrees. Hope this helps!
Your drawer contains seven red socks and five green socks. It's too dark to see which are which. What is the
probability that the two socks that you pick are both red if you don't replace the first sock after you draw it?
7/24
7/12
7/15
14/35
Answer:
7/22
Step-by-step explanation:
Probability of picking a red sock the first time: 7/12
Probability of picking a red sock the second time: 6/11 (Since you already took out one sock, thus decreasing both the number of red and total socks in the drawer.)
7/12 * 6/11 = 42/132
42/132 = 7/22

Answer:
First Option; 40,
Second Option; x = 3,
Third Option; x = - 5,
Fourth Option; x = 0
Step-by-step explanation:
Given the expression x^2 + 3 * ( x + 4 ), where x = 4;
x^2 + 3 * ( x + 4 ) ⇒ Substitute the value of 4 in replacement of x,
( 4 )^2 + 3 * ( 4 + 4 ) ⇒ Add the terms in ( ), taking 4^2 at the same time,
16 + 3 * ( 8 ) ⇒ By PEMDAS, multiply 3 by 8 first,
16 + 24 ⇒ And now add the remaining terms,
Solution; 40
This next equation is given to be 5 * ( 2x - 1 ) = 25, where we must solve for x;
5 * ( 2x - 1 ) = 25 ⇒ Distribute the 5 to the terms in ( ),
10x - 5 = 25 ⇒ Add 5 on either side of the equation,
10x = 30 ⇒ Divide 10 on either side of equation,
Solution; x = 3
Here we must solve for the value of x provided the equation 6x + 4 - x = 2x - 11;
6x + 4 - x = 2x - 11 ⇒ Add 11 on either side,
6x + 15 - x = 2x ⇒ Add x on either side of equation,
6x + 15 = 3x ⇒ Subtract 6x on either side,
15 = - 3x ⇒ Divide 3 on either side,
Solution; x = - 5
Now we are given the equation 4 - ( 3x + 4 ) = - 9x, solving for the value of x;
4 - ( 3x + 4 ) = - 9x ⇒ Distribute the - 1 to all terms in ( ),
4 - 3x - 4 = - 9x ⇒ Add 3x on either side of equation,
4 - 4 = - 6x ⇒ Subtract 4 from 4,
0 = - 6x ⇒ Divide - 6 on either side,
Solution; x = 0
