Answer:
The area is 49.5 cm^2
Step-by-step explanation:
To find the area of the sector, we are going to use the formula for the area of a sector
Mathematically, we have this as;
A = theta/360 * pi * r^2
r = 9 cm and theta = 70
Substituting these values
A = 70/360 * 3.142 * 9^2
A = 49.5 cm^2
How many 5-card hands can be dealt from a standard deck of 52 cards?
Answer:
2,598,960
Step-by-step explanation:
Answer:
The 2598960 cards can be dealt from a standard deck of 52
cards if 5-card selected.
What is permutation and combination?
A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.
We have a standard deck of 52 cards.
5 cards selected.
Total combination:
= C(52, 5)
= 2598960
Thus, the 2598960 cards can be dealt from a standard deck of 52
cards if 5-card selected.

A tree casts a shadow 31 feet long when the angle of
elevation of the sun is 58º. Find the height of the tree.
Answer:
x=24.2198542
ROUND IF NEEDED
Step-by-step explanation:
We are trying to find the height of the tree or the vertical side
We are given
The angle of elevation or the angle at the ground ,38The horizontal length, 31.Since we have a side that is adjacent to that angle and we are trying find backside that us opposite of that angle
we are going to use tangent
[tex] \tan(x) = \frac{opp}{adj} [/tex]
plug 38 in for x or theta, x for opp side and 31 for adjacent side
[tex] \tan(38) = \frac{x}{31} [/tex]
Multiply 31 by both sides to find x
x=24.2198542
ROUND IF NEEDED.

what is 6 divided by 1,932
Step-by-step explanation:
do u mean 1,932 divided by six?
Answer:
1932 divided by 6 in decimal = 322
1932 divided by 6 in fraction = 1932/6
1932 divided by 6 in percentage = 32200%
Step-by-step explanation:
The number 1932 is called the numerator or dividend, and the number 6 is called the denominator or divisor.
The quotient of 1932 and 6, the ratio of 1932 and 6, as well as the fraction of 1932 and 6 all mean (almost) the same:
1932 divided by 6, often written as 1932/6. 1932 divided by 6 = 322
The result of 1932/6 is an integer, which is a number that can be written without decimal places.
1932 divided by 6 in decimal = 322
1932 divided by 6 in fraction = 1932/6
1932 divided by 6 in percentage = 32200%
A day at the spa costs $125. You leave a 20% tip. How much tip did you leave?
Answer: $25

Find the missing angle or find X?
Help pls I need it now
Answer and Step-by-step explanation:
So, the format you should choose is the second one.
This is what goes in each box:
[4] (p - [6]) = [12]
The 4 is multiplying the price for 1 of the items (and it is 4 because there are 4 items), the 6 is taking away 6 dollars (because coupons take away money from amount) and 12 is the total amount of money.
Now, we solve for p.
Divide each side by 4.
p - 6 = 3
Now, add 6 to each side.
p = 9.
Each item cost 9 dollars.

Step-by-step explanation:
Here it is given that 0 is less than equal to X so answer will be you should point the mark on 0Which expression is equivalent to 2x ^ 2 - 2x + 77 ? (4x + 1.2) + (2x ^ 2 - 6x + 5) (x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) (4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) (5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13)
Answer:
None of the answers provided are equivalent
Step-by-step explanation:
To solve it would be best to simplify each of the expressions you have listed by combining like terms all the x^2 terms have been bolded, the x terms italicized, and the constant terms are underlined
(4x + 1.2) + (2x ^ 2 - 6x + 5) = 2x ^ 2 - 6x + 6.2
(x ^ 2 - 5x + 13) + (x ^ 2 + 3x - 6) = 2x^2 -2x +7
(4x ^ 2 - 6x + 11) + (2x ^ 2 - 4x + 4) = 6x^2 -10x +15
(5x ^ 2 - 8x + 120) + (- 3x ^ 2 + 10x - 13) = 2x^2 + 2x + 107

Answer:
12x= 180
Step-by-step explanation:
The sum of a triangle always adds up to 180 so,
(4x-1)+ (2x-1) +6 = 180
12x=180
x=15
Answer:
The equation you could use is the 3rd solution. You need to add all of the nubers that have an x after it because you can't add a number that doesn't have x and a number that does have x. So once you add all of those, you add the 10, and keep the subtrction symbol instead of the addition symbol. And like I said before, all triangles are equal to 180.

A car traveling at 72 kilometers per hour. Find the car’s speed in one meter per second?
Given: 2x^2+ 32x + 16 = 0
Step 1: x^2+ 16x +8=0
Step x^2+ 16x = -8
Write numbers in each box to correctly complete the square In Step 3.
Step 3: x^2+ 16x +
Answer:
Step 3: x² + 6x + 64 = -8 + 64
Step-by-step explanation:
At step 3 add 64 on both sides to complete the square.
so x² + 6x = -8
becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.
continuing from there, we get
x² + 6x + 64 = 56
we then use a² + 2ab + b² = (a + b)² on the left side to get
(x + 8)² = 56 (solve the equation for x)
by taking the root on both sides
√(x + 8)² = √56
x + 8 = +- 2√14 (separate the equations
x + 8 = 2√14
x + 8 = -2√14
Solving for x
x = 2√14 - 8 or x = -2√14 - 8
