Answer:
5[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value of
sin60° = [tex]\frac{\sqrt{3} }{2}[/tex], then
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex]
Multiply both sides by 10
10 × sin60° = x
10 ×[tex]\frac{\sqrt{3} }{2}[/tex], hence
x = 5[tex]\sqrt{3}[/tex]
A 16 oz. package of brown rice costs 79 cents and 32 oz. package of white rice costs $3.49. Which package is a better deal?
Answer:the brow
Step-by-step explanation: you can just make the brown rice weigh as much as the white, 32 or 16.(16x2 is 32 and 32/2 is 16). 79 plus 79 is 1.68. Making the 32 oz of brown 1.68. Showing that the brown is cheaper.
Answer:
A 16 oz. package of brown rice for 79 cents is better deal.
Step-by-step explanation:
79 cents/16 oz≈4.94 cents / oz - 1st package
349 cents/32 oz≈10.91 cents/oz - 2 nd package
For the second package price per oz is more. So 1st package is better deal.
The mass of an object changes with location or altitude above the Earth's surface.
True
False
False, the mass of an object never changes. The weight of an object may vary due to the location but the mass never changes. The mass is said to be changes only when an object travels very fast ( like close to speed of light).But not in the above mentioned cases.
Answer:
False
Step-by-step explanation:
Mass is defined as the amount of matter within an object which will never change. This question is trying to trick you since most people use the words mass and weight interchangeably which is not true. Weight is the amount of gravitational force acting upon you which does change with altitude but mass does not.
What is the solution to
5x + 6 ≥ -34 AND -2x - 2 > -10
PLZ HELP FAST ILL GIVE BRAINLEST
Answer:
-8 ≤ x < 4Step-by-step explanation:
5x + 6 ≥ -34 subtract 6 from both sides
5x + 6 - 6 ≥ -34 - 6
5x ≥ -40 divide both sides by 5
x ≥ -8
and
-2x - 2 > -10 add 2 to both sides
-2x - 2 + 2 > - 10 + 2
-2x > -8 change the signs
2x < 8 divide both sides by 2
x < 4
We have x ≥ -8 and x < 4 ⇒ -8 ≤ x < 4

1.2,3,7.5,18.75, which formula can be used to describe the sequence
Answer:
[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]
Step-by-step explanation:
If we observe the given sequence, we find that the ratio of two consecutive terms is the same. i.e.
[tex]\frac{3}{1.2}=2.5\\\\\frac{7.5}{3}=2.5\\\\ \frac{18.75}{7.5}=2.5[/tex]
Such a sequence in which the ratio of consecutive terms remain the same is know as Geometric Sequence. Following formula is used to represent a Geometric Sequence:
[tex]a_{n}=a_{1}\times(r)^{n-1}[/tex]
Here:
[tex]a_{n}[/tex] is the general term. Using the value of n =1,2,3 ... will give us the term of the sequence.
[tex]a_{1}[/tex] is the first term which is 1.2 in this case.
r represents the common ratio which is 2.5.
Using these values we get:
[tex]a_{n}=1.2 \times(2.5)^{n-1}[/tex]
This formula can be used to represent the given sequence.

Answer: I think B is the correct answer, I am not 100% postive though. I am about 98%.
Step-by-step explanation:
For this case we have that, by definition of properties of powers and roots, it is fulfilled that:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
Now, from option B we have:
[tex](\sqrt [m] {x ^ a}) ^ b = (x ^ {\frac {a} {m}) ^ b[/tex]
By definition of power properties we have:
[tex](a ^ n) ^ m = a ^ {n * m}[/tex]

joey can paint a room in 2 hours and chelsea can paint the same room in 3 hours. if they work together how long would it take to paint the room
Answer:
[tex]1.2\ hours[/tex]
Step-by-step explanation:
we know that
Joey can paint a room in 2 hours
That means
Joey can paint the 100% of the room-------> 2 hours
so
In 1 hour ------> can paint 100%/2=50%
Chelsea can paint a room in 3 hours
That means
Chelsea can paint the 100% of the room-------> 3 hours
so
In 1 hour ------> can paint (100%/3)=33.33%
therefore
Joey and Chelsea in 1 hour can paint -----> 50%+33.33%=83.33%
by proportion
[tex]\frac{1}{83.33}\frac{hour}{\%} =\frac{x}{100}\frac{hour}{\%}\\ \\x=100/83.33\\ \\ x=1.2\ hours[/tex]
Sharon purchased a sprinkler system for $1,950 using a six-month deferred payment plan. The interest rate after the introductory period is 23.99%. No down payment is required, but there is a minimum monthly payment of $25. What is the balance at the beginning of the seventh month if only the minimum payment is made each month during the introductory period?(4 points) $1,950.00 $2,045.91 $1,800.00 $2,195.91
Answer:
$1800
Step-by-step explanation:
If we pay $25 monthly, then at the beginning of the seventh month you should have paid:
$25*6 = $150
At the beginning of the seventh month we will have:
$1950 - $150 = $1800.
No interested is charged during the introductory period, so at the beginning of the seventh month the balance will be $1800.
Answer:
it is $2,045.91

11. The scale for a drawing of the tennis court is
1 centimeter = 2 meters. What is the area of
the actual tennis court?
Width
5.5 cm
- Length 10 cm
show steps
Answer:
I believe the correct answer would be 220 meters.
Step-by-step explanation:
If one centimeter equals 2 meters, then you would have to multiply the width (5.5 cm.) by 2 and the length (10 cm.) by 2. After you multiply those, you get 11 meters for the width and 20 meters for the length. You then multiply those by each other, so 11x20, and you get 220.
The actual length and width will be 20 meters and 11 meters. Then the area of the rectangle will be 220 square meters.
What is the area of the rectangle?Let L be the length and W be the width of the rectangle.
Then the area of the rectangle will be
Area of the rectangle = L×W units
The scale for a drawing of the tennis court is 1 centimeter = 2 meters. Then the area of the actual tennis court will be
Width = 5.5 cm
Length = 10 cm
Then the actual length and width will be
L = 10 x 2 = 20 meters
W = 5.5 x 2 = 11 meters
Then the area of the rectangle will be
A = 20 x 11
A = 220 square meters

Is the answer A, B, C or D?
A. this is because when you multiple 280 by 9 you get 2,520 and to get 25% multiple that number by .25 and get 630, add 2520 and 630 to get 3150 ,, subtract 3114 from 3150 to get 36
Answer:
A. He will break the record by 36 yards.
Step-by-step explanation:
Last year:
average yards per game: 280 yards
Increase by 25%:
average yards = 125% of 280 yd = 1.25 * 280 yd = 350 yd
By increasing the yards per game by 25% he will have an average of 350 yd per game this year.
The school record is 3,114 yd, so the average per game for a 9-game season is: 3,114 yd/9 = 346 yd.
He will pass the record by 350 yd - 346 yd = 4 yd per game.
In a 9-game season, he will break the record by 9 * 4 yd = 36 yd.
Answer: A. He will break the record by 36 yards.

Your parents ask you to choose between two offers for an allowance.
The first offer is to receive one penny on the first day, 2 penny’s on the second day, 4 pennies on the third day, 8 pennies on the fourth day and so on. (365 days).
Second offer is to receive 10 dollars the first week, 20 dollars the second week, 30 dollars the third week, and so on, for the entire year (52 weeks).
Which offer should you choose to make more money?
Answer:
The pennies
Step-by-step explanation:
We can create a geometric equation for the pennies and an arithmetic equation for the dollars.
The format for a geometric equation is
[tex]y=a_1(\frac{1-r^n}{1-r} )[/tex]
If we plug in the values we already know we should get the equation.
[tex]y=2^x-1[/tex]
Now we can plug in the number of days in a year for [tex]x[/tex] to find how much money we get.
[tex]2^{365}=7.52*10^{109}[/tex]
Which is basically 752 with 107 zeros following it.
Then we can divide this number by 100 to find the number of dollars it is.
We get 752 with 105 zeros following it.
Now we can find the arithmetic equation for the dollars.
We can see that 10 dollars is being added every time.
Use the formula.
[tex]a_n=a_1+m(n-1)[/tex]
We can plug in.
[tex]a_n=10+10(n-1)[/tex]
Now we can substitute 52 for [tex]x[/tex] in the equation.
[tex]a_{52}=10+10(52-1)[/tex]
[tex]a_{52}=10+510 \\ \\a_{52}=520[/tex]
So you'll be getting 520 dollars at the end of the year, which is far less than the amount of money you get from the pennies.
