Answer:
72
Step-by-step explanation:
He makes 18/30 passes. We need to see how many passes he can make out 120, so we need to see how many times 30 goes into 120.
120/30=4
So 120 is equivalent to 4 30s. Now to find out how many passes he'd make we multiply 18 by 4.
18*4=72
In the year 2000 the population of Mexico was about 100 million, and it was growing by 1.53% per year. At this growth rate, the function f(x) = 100(1.0153)^x gives the population, in millions, x years after 2000. Using this model, in what year would the population reach 118 million? Round your answer to the nearest year.
Answer:
11 years
Step-by-step explanation:
Set the function f(x) = 100(1.0153)^x = to 118 and solve for x:
100(1.0153)^x = 118
Taking the natural logarithm of both sides, we get:
ln 100 + x ln 1.0153 = ln 118
Then x ln 1.0153 = ln 118 - ln 100, or
= 4.7707 - 4.6052
... which leads to:
4.7707 - 4.6052
x = --------------------------- = 11 years (rounded up from 10.888 )

Surface area of a cylinder with a radius and height of 1.5 m
Answer:
28.27
Step-by-step explanation:
Answer:
The surface area of cylinder = 28.26 m²
Step-by-step explanation:
Points to remember
Surface area of cylinder = 2πr(r + h)
Where r - Radius of cylinder and
h - Height of cylinder
To find the surface area of given cylinder
Here r = 1.5 m and h = 1.5 m
Surface area = 2πr(r + h)
= 2 * 3.14 * 1.5(1.5 + 1.5)
= 2 * 3.14 * 1.5 * 3
= 28.26 m²
Therefore the surface area of cylinder = 28.26 m²
Please find the value of the expression below.
Answer:
35
Step-by-step explanation:
Note that the absolute value always produces a positive result
Given
| a² - 2ac + 5c | ← substitute in given values
= | (- 3)² - 2(- 3 × - 4) + (5 × - 4) |
= | 9 - 24 - 20 | = | - 35 | = 35
They give you the equation:
[tex]|a^{2} - 2ac + 5c|[/tex]
We know that:
a = -3
b = 2
c = -4
You can replace the variables with their corresponding values like this:
[tex]|(-3)^{2} -2(-3)(-4) + 5(-4)|[/tex]
You can then go on and do PEMDAS to solve this:
First the exponents:
[tex]-3^{2} = 9[/tex]
[tex]|9 -2(-3)(-4) + 5(-4)|[/tex]
Then you can multiply all that needs to be multiplied together from left to right:
[tex](-2)(-3)(-4) = (6)(-4) = -24[/tex]
[tex]|9 - 24 + 5(-4)|[/tex]
[tex](5)(-4) = -20[/tex]
[tex]|9 - 24 + (-20)|[/tex]
[tex]|9 - 24 -20|[/tex]
Now from left to right subtract:
9 - 24 = -15
[tex]|-15 -20|[/tex]
-15 - 20 = -35
[tex]|-35|[/tex]
^^^The | | mean to take the absolute value of the number. In other words make it positive
So the answer to this is 35

Answer:
For Answer 7 its the first one (x + 6) • (x - 7)
Step-by-step explanation:
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-x-42
The first term is, x2 its coefficient is 1 .
The middle term is, -x its coefficient is -1 .
The last term, "the constant", is -42
Step-1 : Multiply the coefficient of the first term by the constant 1 • -42 = -42
Step-2 : Find two factors of -42 whose sum equals the coefficient of the middle term, which is -1 .
-42 + 1 = -41
-21 + 2 = -19
-14 + 3 = -11
-7 + 6 = -1 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and 6
x2 - 7x + 6x - 42
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-7)
Add up the last 2 terms, pulling out common factors :
6 • (x-7)
Step-5 : Add up the four terms of step 4 :
(x+6) • (x-7)
Which is the desired factorization
Final result :
(x + 6) • (x - 7)

A fountain is located between two trees. Each tree has a height of 60 feet. The angles of elevation from the
base of the fountain to the top of each tree are 64° and 48° as shown below.
What is the horizontal distance between the two trees (rounded to the nearest foot)
A 40
B 837
C 147
D 190 ft
The answer is:
The correct option is:
B) 83 feet
Why?To solve the problem, we need to use the following trigonometric identity:
[tex]Tan(\alpha)=\frac{Opposite}{Adjacent}[/tex]
Which, translated to our problem, will be:
[tex]Tan(\alpha)=\frac{Height}{Base}[/tex]
We are given two triangles, and we know their height and their angles between their hypothenuse and their bases.
So,
For the first triangle, we have:
[tex]height=60ft\\\alpha=64\°[/tex]
So, using the trigometric identity of the tangent, we have:
[tex]Tan(\alpha)=\frac{Height}{Base}\\\\Tan(64\°)=\frac{60ft}{Base}\\\\Base=\frac{60ft}{Tan(64\°)}=\frac{60ft}{2.05}=29.27ft[/tex]
Therefore, we have that the base of the first triangle is equal to 29.27 feet.
For the second triangle, we have:
[tex]height=60ft\\\alpha=48\°[/tex]
So, using the trigometric identity of the tangent, we have:
[tex]Tan(\alpha)=\frac{Height}{Base}\\\\Tan(48\°)=\frac{60ft}{Base}\\\\Base=\frac{60ft}{Tan(48\°)}=\frac{60ft}{1.11}=54.05ft[/tex]
Therefore, we have that the base of the second triangle is equal to 54.05 feet.
Now, to calculate the horizontal distance between the two trees (x), we need to use the following formula with the obtained values of both triangles:
[tex]HorizontalDistance=FirstTriangleBase+SecondTriangleBase\\\\HorizontalDistance=29.27ft+54.05=83.29ft[/tex]
Hence, we have that the distance between the two trees rounded to the nearest foot is 83 feet.

Urgent! Please answer using the screenshot below!!
Answer:
h = 12 units
Step-by-step explanation:
Area of a Parallelogram = base × perpendicular height (A = b × h)
In the diagram above we can obtain the following:
Area = 72 units² perpendicular height = h base = 6(Please Note: the base of a parallelogram must be perpendicular to its height; in this case it is the side measuring 6 units that is perpendicular to the height)
Since A = b × h
⇒ A ÷ b = b ÷ b × h (dividing both sides by b)
⇒ h = A ÷ b (making h the subject of the eq'n)
thus h = 72 unit² ÷ 6 units
= 12 units

Wei has $150.00 to make a garland using 60-cent balloons. He wants to purchase 100 blue balloons and some number of white balloons. He learns that the white balloons are on sale for half price. He writes and solves an equation to find the number of white balloons he can purchase.
Answer:
Step-by-step explanation
i believe the answer is 300
100 times 60 cents would be 60.00$
the question states that the white balloons are half off making it 30 cents
300 times 30 is 90.00
90.00 plus 60.00 would be 150.00$
300 white balloons is what he may purchase
He can purchase 300 white balloons.
Wei can purchase 100 blue balloons for $60.00 (100 * $0.60). He has $150.00 - $60.00 = $90.00 left to spend on white balloons. Since the white balloons are on sale for half price, each white balloon costs $0.60 / 2 = $0.30. Therefore, Wei can purchase $90.00 / $0.30 = 300 white balloons. In total, he can purchase 100 blue balloons and 300 white balloons for the garland.
To calculate the number of white balloons Wei can purchase, we first find the total cost of the blue balloons, which is 100 * $0.60 = $60.00. Then, we subtract this from Wei's budget of $150.00 to find the remaining amount for white balloons: $150.00 - $60.00 = $90.00.
Since the white balloons are on sale for half price, each white balloon costs $0.60 / 2 = $0.30. We divide Wei's remaining budget by the cost per white balloon to find how many he can purchase: $90.00 / $0.30 = 300 white balloons.
So, Wei can purchase 100 blue balloons and 300 white balloons for the garland.
Complete question:
Wei has $150.00 to make a garland using 60-cent balloons. He wants to purchase 100 blue balloons and some number of white balloons. He learns that the white balloons are on sale for half price. He writes and solves an equation to find the number of white balloons he can purchase.
The exact value of cos(17pi/8) is
[tex]\frac{\sqrt{2 + \sqrt2}}{2}[/tex]
Answer:
Step-by-step explanation:
Note that 17pi/8 can be rewritten as 16pi/8 + 1pi/8. 16pi/8 represents 2 full rotations around the center and can be ignored if we just want the cosine of the angle 17pi/8. We are left then with 1pi/8.
We need to find the cosine of this angle. Note that 1pi/8 is 1/2 of 1pi/4, so this situation calls for use of the half angle formula
1 + cos Ф
cos Ф/2 = √(---------------). Here Ф = π/4, and half that is ω = π/8, and the
2 cosine of π/4 is 1/√2.
1 + 1/√2 √2 + 1 2 + √2
So we get cos pi/8 = √( -------------- ) = √ ------------- = √ ---------------

What is the equation of a circle with center (3, 8) and radius 2?
Answer:
(x - 3)² + (y - 8)² = 4
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (3, 8) and r = 2
(x - 3)² + (y - 8)² = 4 ← equation of circle
The equation of a circle with center (3, 8) and radius 2 will be given as
[tex]( x -3 )^2 + ( y -8 )^2 = 4[/tex].
Equation of circle is given as,
[tex]( x -a )^2 + ( y -b )^2 = r^2[/tex]
where,
(a,b) are the coordinates of the center of the circle in form (x, y),
r is the radius of the circle.
Now, the equation of a circle with center (3, 8) and radius 2.
Given to us,
a = 3,
b = 8,
r = 2.
substituting the values,
[tex]( x -a )^2 + ( y -b )^2 = r^2[/tex]
[tex]( x -3 )^2 + ( y -8 )^2 = 2^2[/tex]
[tex]( x -3 )^2 + ( y -8 )^2 = 4[/tex]
Hence, the equation of a circle with center (3, 8) and radius 2 will be given as [tex]( x -3 )^2 + ( y -8 )^2 = 4[/tex].

Two people share £350 in the ratio 1 : 6.
Calculate each share.
Answer:
£50 and £300
Step-by-step explanation:
Sum the parts of the ratio 1 + 6 = 7 parts
Divide the amount by 7 to find the value of one part of the ratio
£350 ÷ 7 = £50 ← value of 1 part of ratio
Hence
1 person receives £50
the other person receives 6 × £50 = £300
To find the two shares in the given ratio, divide the total amount by the sum of the ratio. The first share is 1/7 of the total, while the second share is 6/7 of the total.
Explanation:To find the two shares, we need to divide £350 into two parts using the ratio 1:6. To do this, we must first understand that the ratio sum is 1+6=7.

Given f(x) = 3x - 1 and 9(x) = 2x-3, for which value of x does g(x)=f(2)?
Answer:
g(x) = f(2) at x = 4
Step-by-step explanation:
Assuming that you meant g(x) = 2x - 3:
Set f(2) = g(x) and solve the resulting equation for x:
f(2) = 3(2) - 1 = g(x) = 2x - 3.
Thus, 6 - 1 = 2x - 3.
Adding 3 to both sides and simplifying the result, we get:
8 = 2x, or x = 4.
g(x) = f(2) at x = 4.

Allison, Brianna, and Celeste went on a hike. Allison brought 9 homemade
cookies and Brianna brought 15 cookies she had made. Celeste forgot to bring
treats, but she had $2.16. Allison and Brianna agreed that if the three were to
share the cookies equally, then the two of them should divide Celeste's money
equitably. Celeste agreed. What was the fair way to divide the money?
I don't get this at all PLEASE HELP!
Answer:
Allison = $0.27
Brianna = $1.89
Step-by-step explanation:
The total cookies that the three girls have are:
Allison's cookies + Brianna's Cookies
= 9+15
=24
There is a total of 24 cookies which has to be divided between the 3.
So
Each girl gets 24/3 = 8 cookies.
Since Celeste had no cookies she will have to pay for the 8 cookies.
Allison had 9, she will give one to Celeste
Brianna had 15 out of which she will use 8 for her self and 7 will be given to Celeste.
Celeste is paying 2.16 for 8 cookies.
Price of one cookie = 2.16/8
=$0.27
So, amount that will be given to Allison = 0.27 * 1 = $0.27
Amount that will be given to Brianna = 0.27 * 7 = $1.89
Each person gets 8 cookies. Allison and Brianna each receive $1.08 of Celeste's $2.16.
To find the fair way to divide Celeste's money, we first need to determine how many cookies each person gets when the total number of cookies is divided equally among them.
Total number of cookies = Allison's cookies + Brianna's cookies
Total number of cookies = 9 cookies + 15 cookies
Total number of cookies = 24 cookies
Now, we'll divide the total number of cookies by the number of people (3) to find out how many cookies each person gets:
Number of cookies per person = Total number of cookies / Number of people
Number of cookies per person = 24 cookies / 3
Number of cookies per person = 8 cookies
So each person will get 8 cookies.
Now, since Celeste forgot to bring treats, Allison and Brianna agreed to divide Celeste's money equally between them. To do this fairly, they'll each receive half of Celeste's money.
Celeste's money = $2.16
Now, we'll find out how much each person gets from Celeste's money:
Amount per person = Celeste's money / Number of people
Amount per person = $2.16 / 2
Amount per person = $1.08
So each person will receive $1.08 from Celeste's money.
In summary:
- Each person will get 8 cookies.
- Each person will receive $1.08 from Celeste's money.
