On Tuesday afternoon at camp, Walter did archery and sailing before dinner. He spent 1 hour at archery and 1 hour and 20 minutes sailing. Sailing ended at 2:30 P.M. when it was time for dinner. What time did archery start?
Answer:
12:10
Step-by-step explanation:
1 hour and 20 minutes sailing- sailing ended at 2:30 pm when it was time for dinner.
For this, you simply have to subtract nd hour and 20 minutes from 2:30:
That is 1:10 pm.
Then, Walter spent an hour doing archery, so you take an hour off- which turns it back to 12:10 pm.
or 10 minutes after noon.
Thus, Archery started at 12:10 pm

A triangle has two sides of length 19 and 18. What is the largest possible whole-number length for the third side?
Answer:
36
Step-by-step explanation:
For the largest possible whole number length, this means it would have to be the longest side. Let's let this third side have a length of x.
By the triangle inequality theorem, 19+18>x, which means x<37.
So, the largest possible whole number length for the third side is 36.

45 in
5 in
Volume 0.5 pint
Volume 1 pint
The height of the smaller funnel is about
inches.
The height of the larger funnel is about
inches.
Considering the volume of a cone, it is found that:
The height of the smaller funnel is about 2.72 inches.The height of the larger funnel is about 3.06 inches.What is the volume of a cone?
The volume of a cone of radius r and height h is given by:
[tex]V = \frac{\pi r^2h}{3}[/tex]
For cone 1, we have that V = 0.5 x 28.875 = 14.4375 in³ and r = 2.25 in(half the diameter), hence:
[tex]\frac{\pi (2.25)^2h}{3} = 14.4375[/tex]
[tex]h = \frac{14.4375 \times 3}{\pi \times (2.25)^2}[/tex]
[tex]h = 2.72[/tex]
For cone 2, we have that V = 28.875 in³ and r = 3 in, hence:
[tex]\frac{\pi (2.25)^2h}{3} = 28.875[/tex]
[tex]h = \frac{28.875 \times 3}{\pi \times (3)^2}[/tex]

The prime factorization of 100 is 4x25. Show a factor tree!
Answer:
See details below:
Step-by-step explanation:
We can start with the biggest factors and work our way down to see how arrive at 4 * 25.
In this case, the first part of the tree would be 50 * 2.
2 is prime, but 50 is not and thus must be factored.
Two possible factors of 50 are 2 and 25.
The 25 is not a prime number and must be factored further.
Two possible factors of 25 are 5 and 5.
Thus, the prime factorization of 100 is 2*2*5*5.
Then to simplify, we can combine the similar factors: (2*2) * (5*5) = 4*25

Melissa owns a catering company . For lunch and dinner parties , she serves appetizers before each meal. The number of appetizers Melissa serves is directly proportional to the number of guests at the party. For lunch parties, she serves 3 appetizers per guest. For dinner parties, she serves 5 appetizers per guest. When serving 22 guests, what is the difference of the number of appetizers she serves for dinner and the number of appetizers she serves for lunch?
Answer:
44
Step-by-step explanation:
Lunch = 3 appetizers per guest
If there are 22 guests: 22 × 3 = 66 appetizers served
Dinner = 5 appetizers per guest
If there are 22 guests: 22 × 5 = 110 appetizers served
Difference = total dinner appetizers - total lunch appetizers

Y=x-12, y=14 what is x I need someone to answer fast please
Answer:
x = 26
Step-by-step explanation:
If Y= x - 12 and Y = 14
Then we input the value of y which gets us the equation of: 14 = x - 12
Now we add 12 on both sides to isolate the variable.
We ADDED 12 because we needed a way to cross out the - 12 on the right side. Now the equation would be 14+12 = x
Easily we can find that 26=x

A large automobile manufacturing plant produces 1200 new cars every day. a qualitycontrol inspector checks a random sample of 90 cars from one day’s production and finds that 12 of them have minor paint flaws. calculate and interpret a 99% confidence interval for the proportion of all cars produced that day with minor paint flaws.
Using the z-distribution, it is found that the 99% confidence interval is (0.041, 0.2256), and it means that we are 99% sure that the population proportion is in this interval.
What is a confidence interval of proportions?A confidence interval of proportions is given by:
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which:
[tex]\pi[/tex] is the sample proportion.z is the critical value.n is the sample size.In this problem, we have a 99% confidence level, hence[tex]\alpha = 0.99[/tex], z is the value of Z that has a p-value of [tex]\frac{1+0.99}{2} = 0.995[/tex], so the critical value is z = 2.575.
The other parameters are given by:
[tex]n = 90, \pi = \frac{12}{90} = 0.1333[/tex]
Then, the bounds of the interval are found as follows:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1333 - 2.575\sqrt{\frac{0.1333(0.8667)}{90}} = 0.041[/tex]
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.1333 + 2.575\sqrt{\frac{0.1333(0.8667)}{90}} = 0.2256[/tex]
The 99% confidence interval is (0.041, 0.2256), and it means that we are 99% sure that the population proportion is in this interval.

You have $1000 invested for 3 years and get 10% interest.
Answer:
$1331 compounded annually after three years
Step-by-step explanation:
Given the following question:
1000 dollars invested (princpal)....
You invest that 1000 dollars for three years (time)....
Assuming it's compounded annually we need to substitute the values into the formula to calculate compound interest.
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
[tex]P=1000[/tex]
[tex]\frac{r}{n} =\frac{10}{100} =10\div100=0.1[/tex]
[tex]nt=(1)(3)[/tex]
[tex]A=1000(1+0.1)^{(1)(3)}[/tex]
[tex]1\times3=3[/tex]
[tex]A=1000(1+0.1)^{3}[/tex]
[tex]1+0.1=1.1[/tex]
[tex]1.1^3=1.1\times1.1\times1.1=1.331[/tex]
[tex]A=1000\times1.331[/tex]
[tex]1000\times1.331=1331[/tex]
[tex]=1331[/tex]
Which means after a intital investment of 1000 dollars you will have "1331 dollars" after three years compounded annually.

A city has a population of 360,000 people. Suppose that each year the population grows by 3.75% What will the population be after 11 years?
Answer:
508,000 in 11 years
Step-by-step explanation:
3.75% of 360,000 is 13500
So every year the population grows 13500 people
13500 * 11 = 148,500
148,500+360,000=508,000
So in 11 years the population would be 508,000
The lengths of the diagonals of a rhombus are 24cm and 18 cm respectively. What is the perimeter/
keeping in mind that in a rhombus all sides are equal, Check the picture below.
The perimeter of the rhombus is 60 cm if the lengths of the diagonals of a rhombus are 24 cm and 18 cm respectively.
What is a rhombus?A rhombus is a two-dimensional shape with four straight, equal sides and parallels opposite pairs.
This form is similar to a diamond and is what you'd expect to see on a deck of cards to symbolize the diamond suit. Rhombuses can be found in a variety of settings in everyday life.
We have:
The length of the diagonals of the rhombus is 24 cm and 18 cm
As we know in the rhombus the diagonals intersect at the right angle so it makes a right-angle triangle.
So half of the right-angle 24 cm will be perpendicular to the right-angle triangle and half of the 18 cm will be the base of the right-angle triangle.
a = 24/2 = 12 cm
b = 18/2 = 9 cm
From the Pythagoras theorem the length of the hypotenuse:
[tex]c = \sqrt{12^2+9^2}[/tex]
c = 15 cm
Now the perimeter will be:
The perimeter of the rhombus = 4(15) = 60 cm
Thus, the perimeter of the rhombus is 60 cm if the lengths of the diagonals of a rhombus are 24 cm and 18 cm respectively.

The area of a circle is 100π ft². What is the circumference, in feet? express your answer in terms of \piπ
Answer:
20π ft
Step-by-step explanation:
To find the circumference of the circle given its area, first find its radius.
[tex]\textcolor{steelblue}{\boxed{\text{Area of circle =}\pi {r}^{2} }}[/tex]
Substitute given area into the formula:
100π= πr²
Divide both sides by π:
100= r²
Square root both sides:
[tex]r = \sqrt{100} [/tex]
r= 10 ft
[tex]\textcolor{steelblue}{\boxed{\text{Circumference of circle = }2\pi {r}}}[/tex]
Since we have found the value of the radius, we can substitute r= 10 into the formula above to find the circumference.
Circumference of circle
