Answer:
A
Step-by-step explanation:
The figure shown in the right is made up of a square and a circle. Find the perimeter of the shaded region.
A. 16+2π cm
B. 12+2π cm
C. 12+4π cm
D. 16+4π cm
Answer:
B. 12 + 2pi cm
Step-by-step explanation:
The shaded region is made up of 3 square sides and one half circle. The three square sides are each 4, which means that those altogether equal 12.
The circle's circumference can be found by using the equation c = (d)pi
The diameter is 4, so the whole circumference is 4pi. However, you only need half of a circle, which is represented by 2pi.
Add them all together, and you get 12 + 2pi cm.

What is the probability of getting tails and then getting heads?
Write your answer as a percentage.
___%
Answer: 25%
Step-by-step explanation:
You have a 1/2 chance of landing a heads or tails both times. So, you multiply 1/2 *1/2 = 1/4. 1/4 = 0.25 = 25%.

A cone has a volume of 96 'pi' cubic feet. if the radius is 6 feet, what is the height of the cone?
A.8
B.32
Answer:
height of the cone = 8 ft
Step-by-step explanation:
A cone has a volume of 96π ft³. The radius of the cone is 6 ft. The height of the cone can be computed below .
The volume of a cone can be represented as follows
volume of a cone = 1/3πr²h
where
r = radius
h = height
volume of a cone = 1/3πr²h
volume = 96π ft³
r = 6 ft
h = ?
96π = 1/3 × π × 6² × h
96π = 1/3 × π × 36 × h
96π = 12πh
divide both sides by 12π
h = 96π/12π
h = 8 ft
height of the cone = 8 ft
Artur, Olga i Wiktor uczestniczyli w wyścigu. Wystartowali z tego samego miejsca, w tym samym momencie i biegną ze stałymi prędkościami. Gdy Artur ukończył bieg, Olga miała 15 m do mety, a Wiktor miał 35 m. Gdy Olga ukończyła bieg, Wiktorowi pozostały 22 m do mety. Na jakim dystansie został rozegrany wyścig?
Answer:
165m
Question:
Artur, Olga and Wiktor participated in the race. They started from the same place at the same time and run at constant speeds. When Artur finished the race, Olga was 15 m to the finish, and Wiktor was 35 m. When Olga finished the race, Wiktor had 22 m to the finish. At what distance was the race held?
Explanation:
Let distance be x meters
Fist statement:
Artur distance = x
Olga =x-15
Wiktor = x-35
Since they are going at constant speed, time is constant for all 3.
Their speed = distance/time
x/t, (x-15)/t, (x-35)/t respectively
Second statement:
Olga distance = x
Wiktor distance = x-22
Their Time is constant:
If it takes (x-15) in t secs,
for x meters will take = xt/(x-15)
Olga and wiktor respectively: xt/(x-15), xt/(x-15) respectively
Their speed:
Speed = distance/time
Olga = (x-15)/t,
Wiktor = (x-22)(x-15)/(xt)
Since speed is constant
Speed for Wiktor in both cases:
(x-35)/t =(x-22)(x-15)/(xt)
x(x-35) =(x-22)(x-15)
x² -35x = x² - 15x -22x +330
-35x = -37x +330
2x = 330
x = 165m
Race held at 165m distance.

if you have 3,500 after 10 years on an investment that pays 3.5% compounded daily, what was the principle amount you started with ?
Answer: $2,466.45
Step-by-step explanation:
Hi, to answer this question we have to apply the compounded interest formula:
A = P (1 + r/n) nt
Where:
A = Future value of investment (principal + interest)
P = Principal Amount
r = Nominal Interest Rate (decimal form, 3.5/100= 0.035)
n= number of compounding periods in each year (365)
Replacing with the values given
3,500= P (1+ 0.035/365)^365(10)
Solving for P
3,500= P (1.00009589)^3650
3,500/ (1.00009589)^3650 =P
P = $2,466.45
Prime factors of 24x2
Answer:
Step-by-step explanation:
24 is a composite number.
Prime factorization: 24 = 2 x 2 x 2 x 3, which can be written 24 = 2³ x 3
The exponents in the prime factorization are 3 and 1. Adding one to each and multiplying we get (3 + 1)(1 + 1) = 4 x 2 = 8. Therefore 24 has exactly 8 factors.
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
Factor pairs: 24 = 1 x 24, 2 x 12, 3 x 8, or 4 x 6

Can someone please help with this question
Answer:
Option B.
Step-by-step explanation:
The given equation of trend line is
[tex]y=\dfrac{4}{5}x[/tex]
where, x is time in minutes and y is amount of water in gallons.
It is given that the rate (gallons per minute) continues approximately.
We need to find the amount of water flow from the hose in 45 minutes.
Substitute x=45 in the given equation.
[tex]y=\dfrac{4}{5}(45)[/tex]
[tex]y=4\times 9[/tex]
[tex]y=36[/tex]
It means 36 gallons of water from hose in 45 minutes.
Therefore, the correct option is B.

Answer:
4.41
Step-by-step explanation:
We can use trig to solve for the missing side (specifically cosine). cos(x)=adjacent side/hypotenuse. We have the x value (which is the angle shown) which is 25. We have the adjacent side of that angle which is 4. We are solving for the hypotenuse (lets call that h). When we plug in values into the equation cos(x)=adjacent/hypotenuse, we get cos(25)=4/h. cos 25=0.9063. So 0.9063=4/h. Multiply both sides by h and we get 0.9063h=4. Now divide 0.9063 on both sides to isolate h and we get 4.4135... but since you want hundredths, its 4.41

what is the answer to the following question.
7/2 times 5 times 7/5
Answer:
24 1/2
Step-by-step explanation:
First multiply 7/2 by 5.
7/2 x 5 = 35/2
Then, multiply 35/2 by 7/5.
35/2 x 7/5 = 245/10
Simplify 245/10.
245/10 = 49/2
Convert to mixed fraction.
49/2 = 24 1/2
Therefore, the simplest form of 7/2 x 5 x 7/5 is 24 and 1/2.

A laboratory tested n = 110 chicken eggs and found that the mean amount of cholesterol was LaTeX: \bar{x}x ¯ = 92 milligrams with σ = 8 milligrams. Find the margin of error E corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs.
Answer:
The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1-0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1-\alpha[/tex].
So it is z with a pvalue of [tex]1-0.025 = 0.975[/tex], so [tex]z = 1.96[/tex]
Now, find the margin of error E as such
[tex]E = z*\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
In this question:
[tex]\sigma = 8, n = 110[/tex]. So
[tex]E = 1.96\frac{8}{\sqrt{110}} = 1.495[/tex]
The margin of error corresponding to a 95% confidence interval for the true mean cholesterol content, μ, of all such eggs is of 1.495 miligrams.

Javier's parents set an amount of money aside when he was born. They earned 4.5% simple interest on that money each year. When Javier was 15, the account had a total of $1012.50 interest paid on it. How much did Javier's parents set aside when he was born
Answer:
Javier's parents set aside $1500 when he was born
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
In this question, we have that:
[tex]E = 1012.50, t = 15, I = 0.045[/tex]
We have to find P. So
[tex]E = P*I*t[/tex]
[tex]1012.50 = P*15*0.045[/tex]
[tex]P = \frac{1012.50}{15*0.045}[/tex]
[tex]P = 1500[/tex]
Javier's parents set aside $1500 when he was born
