During the winter season, the number of visitors to a theme park decreased by 700 to 2,100. What was the theme park's population at the beginning of the winter season?
Answer: 2800
Step-by-step explanation:
From the question, we are informed that during the winter season, the number of visitors that came to a theme park decreased by 700 to 2,100.
Therefore, the theme park's population at the beginning of the winter season will be gotten by adding 700 and 2100. This will be:
= 700 + 2100
= 2800

Answer:
KN ≈ 20.7 cm
Step-by-step explanation:
Using Pythagoras' identity in right triangle KLM to find KM
LM² = KL² + KM²
28² = 16² + KM²
784 = 256 + KM² ( subtract 256 from both sides )
528 = KM² ( take the square root of both sides )
[tex]\sqrt{528}[/tex] = KM
----------------------------------------
Using the sine ratio in right triangle KMN
sin64° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{KN}{KM}[/tex] = [tex]\frac{KN}{\sqrt{528} }[/tex] ( multiply both sides by [tex]\sqrt{528}[/tex]
[tex]\sqrt{528}[/tex] × sin64° = KN , that is
KN ≈ 20.7 cm ( to 1 dec. place )

Find the sum of the infinite geometric sequence:
8, 4, 2, 1, .......
Answer:
Therefore the sum if the series is 15.98!The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.
8⋅1/2=4
4⋅1/2=2
2⋅1/2=1 etc ...
because the absolute value of r is less than 1 we can use the following formula.
a/1−r where a is the first term and r is the common ratio
In our problem
a=8 and r=0.5
Substitute
8/1−0.5=8/0.5=16
The sum of this infinite geometric series is 16.
Also, another formula you can use that is guaranteed to work every time, no matter what, is:
Sn=a(r^n−1/r−1)
All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:
S10=8(0.5^10−1/0.5−1)
S10=15.984375
Therefore the sum if the series is 15.98!

can someone please help me
Answer:
C
Step-by-step explanation:
divide both sides by 3
Answer:
C
Step-by-step explanation:
To find out which inequality is equivalent to the one given, solve [tex]-18\leq 3p[/tex]. Solving an inequality is similar to the process of solving an equation. Isolate the variable. Divide both sides by 3:
[tex]-18\leq 3p\\\frac{-18}{3} \leq \frac{3}{3} p\\-6\leq p[/tex]
Now, look at the options. Although the signs are different, [tex]p\geq -6[/tex] and [tex]-6\leq p[/tex] say the same thing. Either way, p is bigger than or equal to -6. Thus, the answer is C.

Step-by-step explanation:
Joshua went to the grocery store and purchased cans of
soup and frozen dinners. Each can of soup has 200 mg
of sodium and each frozen dinner has 400 mg of sodium.
Joshua purchased a total of 10 cans of soup and frozen
dinners which collectively contain 2400 mg of sodium.
Write a system of equations that could be used to
determine the number of cans of soup purchased and
the number of frozen dinners purchased. Define the
variables that you use to write the system.
Answer:c + f = 10
200c + 400f = 2400
Step-by-step explanation:
Let's say c is the number of cans of soup and f is the number of frozen dinners.
The total number of items is 10:
c + f = 10
The total amount of sodium is 2400 mg. Each can of soup has 200 mg, and each frozen dinner has 400 mg.
200c + 400f = 2400
The problem doesn't ask you to solve the system, but I'll solve it anyway. We can use substitution or elimination. But first, simplify the second equation by dividing both sides by 200.
c + 2f = 12
Using elimination, subtract the first equation.
f = 2
Plug into either equation to find c:
c = 8
There are 8 cans of soup and 2 frozen dinners.

Answer is 16 because 16/4 = 4 + -12 = -8
Answer:
m=16
Step-by-step explanation:
-8=m/4+(-12)
4=m/4
16=m
so first, you add 12 to the other side to cancel out the -12. 12-8=4. so now you have 4=m/4. to isolate the m, you have to multiply by 4 on both sides, which gives you 16=m or m=16.
i hope this helps :)

why is the equation y = mx + b called the slope - intercept form?
Answer:
Step-by-step explanation:
The equation y = mx + b is called the slope-intercept form because both the slope and y-intercept are represented. The variable m, stands for slope, and the variable b, stands for slope.
find the surface area of a cone with radius 5 ft and height 21 ft substitute pi for 3.14
Answer:
417.4ft^2
Step-by-step explanation:
Surface area of a cone = πr(r+√r²+h²)
r is the radius
h is the height
Substitute
Surface area of a cone = π(5)(5+√5²+21²)
Surface area of a cone = πr(5+√25+441)
Surface area of a cone = π(5)(5+21.59)
Surface area of a cone = 3.14*5*26.59
Surface area of a cone = 417.4ft^2
Hence the surface area of the cone is 417.4ft^2

Ally has 86 coins, of which 32 are pennies. The rest of the coins are dimes. Which proportion can Ally use to find p, the percent of her coins that are dimes?
The expression used to represent the percent of her coins that are dimes is P / 100 = 32 / 86
Percentage is a number or ratio expressed as a fraction of 100.
Let P represent the percent of coins that are dimes. Since there are 86 coins and 32 are dimes. The value of P is:
P = (32/86) * 100%
P / 100 = 32 / 86
The expression used to represent the percent of her coins that are dimes is P / 100 = 32 / 86
