Answer:
95 balloons
Step-by-step explanation:
red = 40
green- 40x(3/5) = 24
yellow- 24÷(2/3) =36
36× (1/36) = 1. 1 yellow balloon popped
24× (1×12) = 2. 2 green balloons popped
40×(1/20) =2. 2 red balloons popped
40+24+36= 100
2+2+1=5
100-5 = 95 balloons left for decorations
You are looking at the New York ball drop on New Year’s Eve at a distance of 100 m away from the base of the structure. If the ball drops at a constant rate of 2 m/s, what is the rate of change of the
angel between you and the ball when the angle is ( ?
The question is an illustration of related rates.
The rate of change between you and the ball is 0.01 rad per second
I added an attachment to illustrate the given parameters.
The representations on the attachment are:
[tex]\mathbf{x = 100\ m}[/tex]
[tex]\mathbf{\frac{dy}{dt} = 2\ ms^{-1}}[/tex] ---- the rate
[tex]\mathbf{\theta = \frac{\pi}{4}}[/tex]
First, we calculate the vertical distance (y) using tangent ratio
[tex]\mathbf{\tan(\theta) = \frac{y}{x}}[/tex]
Substitute 100 for x
[tex]\mathbf{y = 100\tan(\theta) }[/tex]
[tex]\mathbf{\tan(\theta) = \frac{y}{100}}[/tex]
Differentiate both sides with respect to time (t)
[tex]\mathbf{ \sec^2(\theta) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot \frac{dy}{dt}}[/tex]
Substitute values for the rates and [tex]\mathbf{\theta }[/tex]
[tex]\mathbf{ \sec^2(\pi/4) \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
This gives
[tex]\mathbf{ (\sqrt 2)^2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
[tex]\mathbf{ 2 \cdot \frac{d\theta}{dt} = \frac{1}{100} \cdot 2}[/tex]
Divide both sides by 2
[tex]\mathbf{ \frac{d\theta}{dt} = \frac{1}{100} }[/tex]
[tex]\mathbf{ \frac{d\theta}{dt} = 0.01 }[/tex]
Hence, the rate of change between you and the ball is 0.01 rad per second

Instructions- Solve the system of equations. Type in all points of intersection for the two functions and round to the nearest tenth if necessary.
f(x) = -0.5x+2
8(x) = -5x + 3
f(×)=-0,5x+2
8(×)= -5x+3
8×= -5x+3
8-5x+3
3x+3
x6
The nearest tenth as required, the point of intersection expressed as (0.2, 2.1).
To solve the system of equations, to find the points where the two functions intersect, which means the x-values where f(x) equals g(x). Let's proceed with the solution:
f(x) = -0.5x + 2
g(x) = -5x + 3
Set f(x) equal to g(x):
-0.5x + 2 = -5x + 3
Now, let's solve for x:
Add 0.5x to both sides to eliminate the term with x on the left side:
2 = -4.5x + 3
Subtract 3 from both sides:
-1 = -4.5x
Now, divide by -4.5 to isolate x:
x = -1 / -4.5
x ≈ 0.2222
Now that we have the x-value of the point of intersection, let's find the corresponding y-value by plugging x back into either f(x) or g(x). Let's use f(x):
f(x) = -0.5x + 2
f(0.2222) = -0.5(0.2222) + 2
f(0.2222) ≈ 2.1111
So, the point of intersection is approximately (0.2222, 2.1111).

How long will it take for a $2000 investment to grow to $2786 at an annual rate of 4.6% , compounded quarterly? Assume that no withdrawals are made.
Answer:
7.4
Step-by-step explanation:
use the compound interest formula
I=P(1+r/100)<n
2786=2000(1+4.6/100)^n
divide 2000 by both side
1.393=(1+4.6/100)^n
1.393=1.046^n
introduce the log
log1.393=rlog1.046
divide both with log1.046 to get the value of n

2,276 ≤ 2,336.6 < 60.6
Step-by-step explanation:
I. When m is combined mass of car and person which is
2,276 + 60.6 = 2,336.6
II. Write into the interval a <= m < b
So we can write as
2,276 ≤ 2,336.6 < 60.6 will return to False.
or
60.6 ≤ 2,336.6 < 2,276 will return to False.
That makes 2,276 ≤ 2,336.6 < 60.6 is the right answer.

4/5 of the money collected from a fundraiser was divided equally among 8 grades
What fraction did each grade receive?
Answer:
1/10
Step-by-step explanation:
your equation is 4/5 divided by 8/1.
Lets solve that problem with the acronym KCF, or
Keep
Change
Flip.
K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.
C: "change" the division sign to a multiplication sign, so 4/5x8/1
F: "flip" the second fraction, so 8/1 becomes 1/8.
now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.

What is the solution to the equation −p − 13 = −4 /3 p + 2/3 ( 5p − 6 ) ?
((will give brainliest to best answer
Answer:
The answer is p= 2 and 1/3
Step-by-step explanation:
This answer can be found using the order of operations to solve for p.
Start by distributing 2/3 by (5p-6)
add -4/3p to 10/3p equaling 6/3p or 2p
subtract 13 from both sides
-p= 2p - 7
p=2 and 1/3

Solve for x given the point (x,9) is a point on the line y = 3x + 7.
Answer:
0.67 = x
Step-by-step explanation:
to solve the value of x we need to : (x,9)
y = 3x + 7
9 = 3x + 7
9 - 7 = 3x
2 = 3x
2/3 = x
0.67 = x
From the given point (x , 9) let's plug the value of its y - coordinate of into Equation - y = 3x + 7 and solve for x :
[tex]9 = 3x + 7[/tex][tex]2 = 3x[/tex][tex]x = \dfrac{2}{3} [/tex]hence, value of x = 2/3

Victoria has a cow. The cow’s tail is 3 inches long. The cow’s tail grows by 5 inches every 6 months. What will the tail’s length be next year?
Answer:
The cow's tail will grow 25 inches more intotal
The cows tail will be 28 inches long.
Step-by-step explanation:
12 months equals to one year (leap year not included) cows tail
grows 5 inches every 6 months. So, 5 x 5 = 25 + the 3 inches from its previous tail will give us total for all. so the answer is 28 in all or 25 for how much it has grown.
That's a long tail ;-;
