The total number of campers at the camp is calculted to be 100 campers.

To find the total number of campers at the camp, we need to use the given information about the percentage of campers that went on the hike and the number of campers that went on the hike.

35% = 35 campers / Total number of campers

Cross-multiplying and simplifying gives us:

35% * Total number of campers = 35 campers

Dividing both sides by 35% gives us:

Total number of campers = 35 campers / 35%

Converting 35% to a decimal gives us:

Total number of campers = 35 campers / 0.35

Solving for the total number of campers gives us:

Total number of campers = 100 campers

So the total number of campers at the camp that went on for hike is 100 campers.

The surface area of the frustrum, obtained summing the areas of the trapezium-shaped faces, and the square base and top is 2720 mm²

A frustrum is the part of a pyramid formed when the top is removed by a plane parallel to the base of the pyramid.

The slant height of the small square-based pyramid, is the same as the slant height of the frustrum. The base of the small pyramid therefore intersects the sides of the large pyramid at the midpoint of the sides, which indicates that the base of the small rectangle is a midsegment of the triangular sides of the square-based pyramid.

The midsegment theorem indicates that the side length of the base of the small pyramid is half the side length of the base of the large square-based pyramid. Therefore;

Length of the base of the smaller pyramid = 32 mm/2 = 16 mm

Height of the trapezium-shaped face = √(17² - ((32 - 16)/2)²) = √(17² - 8²) = 15

Area of the trapezium-shaped face = (16 mm + 32 mm) × 15 mm/2 = 360 mm²

The surface area of the four trapezium-shaped faces = 4 × 360 mm² = 1,440 mm²

The area of the square at the top of the frustrum = 16 mm × 16 mm = 256 mm²

The area of the square base = 32 mm × 32 mm = 1024 mm²

Answer:

9.8 feet long

Step-by-step explanation:

We'll assume that the photo is to be scaled up from inches to feet.  The increase in the width dimension is from 5 inches (wide) to 7 feet (wide).  Convert the 7 feet into inches (7'*12" = 84").

Now we can calcullate a ratio of the old scale to the new:

(New Width)/(Old Width) = 84"/5" = 16.8

The phot is being made 16.8 times larger for the poster.

Use the same ratio to scale up the length of 7 inches:

 (7")*(16.8) = 117.6 inches

(117.6")*(1 foot/12") = 9.8 feet long

Step-by-step explanation:

Gradient of a line is the slope of the line

Slope = rise/run

rise = difference in y values between any two points on the line

run = difference in x values between the corresponding points

Line A

Take points (0, 1) and (3,7)
rise = 7 - 1 = 6
run = 3 - 0 = 3

slope = gradient = 6/3 = 2

Gradient of a line which goes diagonally up from left to right is positive

Line B

Take points (0,5) and (5, 0)

rise = 0 - 5  = - 5

run = 5 - 0 = 5

slope = gradient = -5/5 = - 1

Gradient of a line which goes diagonally down from left to right is negative

2) The car travels 98 miles in 14 hours.

3) The orchard can produce 450 liters of olive oil in a year.

What is a ratio?

A ratio is a quantitative comparison between two or more quantities, indicating how many times one quantity contains another. It is expressed as the quotient of the two quantities or in the form of a fraction. Ratios can be represented in various ways, including as decimals, percentages, or fractions.

Complete the table to show the amounts of yellow and red paint needed for different numbers of batches of the same shade of orange paint.

Yellow paint (quarts) | Red paint (quarts)

5 | 3

6 | 3.6

To get the same shade of orange paint, we need to mix yellow and red paint in a certain ratio. This ratio will determine the hue, saturation, and brightness of the final color. In this case, we can see that the ratio of yellow to red paint is 5:3 in the first row of the table, and 6:3.6 (which simplifies to 5:3) in the second row. This means that we need the same amount of yellow and red paint for each batch of orange paint, in a 5:3 ratio.

A car is traveling at a constant speed, as shown by the double number line.

The distance traveled by the car is directly proportional to the amount of time it travels. This means that the ratio of distance to time is constant. From the given double number line, we can see that the car travels 21 miles in 3 hours. Therefore, the ratio of distance to time is 21:3 or 7:1. To find how far the car travels in 14 hours, we can set up a proportion:

distance/time = 7/1

distance/14 = 7/1

distance = 7 x 14

distance = 98 miles

Therefore, the car travels 98 miles in 14 hours.

The olive trees in an orchard produce 3000 pounds of olives per year. It takes 20 pounds of olives to produce 3 liters of olive oil.

To find how many liters of olive oil the orchard can produce in a year, we need to divide the total weight of olives by the amount of olives needed to produce one liter of oil, and then multiply by the conversion factor:

Liters of oil = (Pounds of olives / Pounds per liter) x Conversion factor

Liters of oil = (3000 / 20) x 3

Liters of oil = 150 x 3

Liters of oil = 450

Therefore, the orchard can produce 450 liters of olive oil in a year.

Hence,

To simplify the expression 5x2+2x-4-10x2, we must first combine like terms. Like terms are terms that have the same variable or variables with the same exponents.

In this expression, 5x2 and -10x2 are like terms. To combine them, we can add their coefficients (the numbers in front of the variable) together. So, 5x2 - 10x2 = (-5 + 5)x2 = 0x2.

Now, the expression has only two terms left. 2x and -4 are also like terms, since they both have the same variable. We can again add their coefficients together, which results in (2 + -4)x = -2x.

Therefore, the simplified expression is 0x2 - 2x. Note that there is no need to use the 0x2 term, so the expression can also be written as -2x.

If the velocity of the fisherman is 4.00 m/s when he jumps into the boat, then the final velocity of the fisherman and the boat is 1.78 m/s.

Momentum is a vector quantity, which means that it has both magnitude and direction.

We can solve this problem using the law of conservation of momentum, which states that the total momentum of a system is conserved if there are no external forces acting on it.

The system's starting momentum is determined by:

p1 = m1v1

where p1 is the initial momentum of the fisherman, m1 is his mass, and v1 is his initial velocity. Since the boat is initially at rest, its momentum is zero. As a result, the system's overall initial momentum is:

p1tot = p1 + p2 = m1v1

where p2 is the initial momentum of the boat and is equal to zero.

When the fisherman jumps into the boat, the system becomes a closed system with no external forces acting on it. As a result, the system's overall momentum must be conserved.

p1tot = p2tot

where p2tot is the final momentum of the system. The system's final momentum is determined by:

p2tot = (m1 + m2)vf

where m2 is the mass of the boat, and vf is the final velocity of the boat and the fisherman.

We can rearrange these equations to solve for the final velocity vf:

p1tot = p2tot

m1v1 = (m1 + m2)vf

vf = (m1v1)/(m1 + m2)

Substituting the given values, we get:

vf = (80.0 kg)(4.00 m/s)/(80.0 kg + 100.0 kg)

vf = 1.78 m/s

Therefore, the final velocity of the fisherman and the boat is 1.78 m/s.

For the inequality |x| + 3 > 7, the points which are on its graph is -5 and 7.

What is an inequality?

In Algebra, an inequality is a mathematical statement that uses the inequality symbol to illustrate the relationship between two expressions. An inequality symbol has non-equal expressions on both sides. It indicates that the phrase on the left should be bigger or smaller than the expression on the right, or vice versa.

To solve the inequality |x| + 3 > 7, we need to isolate the absolute value by subtracting 3 from both sides, and then split it into two cases -

|x| > 4 and -(|x|) > 4 (by multiplying both sides by -1)

Simplifying the second inequality, we get -

|x| < -4

But this is impossible, because the absolute value of any number is always non-negative.

Therefore, the second inequality has no solutions.

For the first inequality, we have -

|x| > 4

This means that x is either less than -4 or greater than 4.

Therefore, the points on the graph that satisfy the inequality are -

-5 and any value less than -4

The finance charge for the credit card account for this billing cycle is $96.08.

The finance charge is the cost of consumer credit. It includes any charge payable directly or indirectly by the consumer and imposed directly or indirectly by the creditor as a result of or as a condition of credit extension.

Step 1: To calculate the average daily balance

Daily balance for days 1-29:

= $530 (the balance from last month)

Daily balance for day 30:

=  $530 - $350 payment + $190 dog + $55 pet supplies - $100 vet bill

= $275

The average daily balance for the billing cycle is:

= (29 x $530 + 1 x $275) / 30

= $16,400 / 30

= $546.67

Step 2:

The portion of the balance subject to interest is the average daily balance minus the payment. The portion subject to interest is:

= $546.67 - $350

= $196.67

Step 3: Calculate the interest charged for the billing cycle

Monthly interest rate = 19.6% ÷ 12 = 0.01633

The Interest charged for the cycle is:

= Portion subject to interest x Monthly interest rate x Number of days in the billing cycle

The exact values of the trigonometric functions are

To find the exact value of the trigonometric functions, we will use the reference angle and the quadrant in which the terminal side of each angle is located.

For cos 17π/6, the reference angle is π/6 and the terminal side is in the fourth quadrant. The point on the unit circle in this quadrant with a reference angle of π/6 is (√3/2, -1/2). Therefore, the exact value of cos 17π/6 is √3/2.

For sin 20π/3, the reference angle is π/3 and the terminal side is in the first quadrant. The point on the unit circle in this quadrant with a reference angle of π/3 is (1/2, √3/2). Therefore, the exact value of sin 20π/3 is √3/2.

For tan 15π/4, the reference angle is π/4 and the terminal side is in the third quadrant. The point on the unit circle in this quadrant with a reference angle of π/4 is (-√2/2, -√2/2). Therefore, the exact value of tan 15π/4 is 1.

In summary, the exact values of the trigonometric functions are:
cos 17π/6 = √3/2
sin 20π/3 = √3/2
tan 15π/4 = 1

As the F-ratio = 4.03 is greater than the critical value = 3.89, the null hypothesis is rejected. c. It is concluded that there exist a significant difference in the severity of anxiety symptoms after undergoing the art therapy program between the three cities. d. The eta-squared and omega-squared values are 0.40 and 0.34 respectively.

a. The omnibus null hypothesis is that there is no difference in the severity of anxiety symptoms after undergoing the art therapy program between the three cities. The alternative hypothesis is that there is a difference in the severity of anxiety symptoms after undergoing the art therapy program between the three cities.

H0: μA = μB = μC
H1: μA ≠ μB ≠ μC

b. To conduct an appropriate statistical test, we will use ANOVA (Analysis of Variance). The steps for the calculation are as follows:

Step 1: Calculate the grand mean (GM) of all the scores.

GM = (22+22+40+25+22+34+30+27+30+42+28+27+33+21+39)/15 = 29.6

Step 2: Calculate the sum of squares between groups (SSB).

SSB = 5((22+22+40+25+22)/5 - 29.6)^2 + 5((34+30+27+30+42)/5 - 29.6)^2 + 5((28+27+33+21+39)/5 - 29.6)^2 = 340.4

Step 3: Calculate the sum of squares within groups (SSW).

SSW = (22-24.2)^2 + (22-24.2)^2 + (40-24.2)^2 + (25-24.2)^2 + (22-24.2)^2 + (34-32.6)^2 + (30-32.6)^2 + (27-32.6)^2 + (30-32.6)^2 + (42-32.6)^2 + (28-29.6)^2 + (27-29.6)^2 + (33-29.6)^2 + (21-29.6)^2 + (39-29.6)^2 = 506.8

Step 4: Calculate the mean square between groups (MSB) and the mean square within groups (MSW).

MSB = SSB/dfB = 340.4/2 = 170.2
MSW = SSW/dfW = 506.8/12 = 42.23

Step 5: Calculate the F-ratio.

F = MSB/MSW = 170.2/42.23 = 4.03

Step 6: Compare the F-ratio with the critical value from the F-distribution table with dfB = 2 and dfW = 12 at a significance criterion of 5%.

The critical value is 3.89.

Step 7: Make a decision and state the relevant statistical values.

Since the F-ratio (4.03) is greater than the critical value (3.89), we reject the null hypothesis and conclude that there is a significant difference in the severity of anxiety symptoms after undergoing the art therapy program between the three cities. The relevant statistical values are F(2,12) = 4.03, p < 0.05.

c. The statistical conclusion for the outcome in (b) is that there is a significant difference in the severity of anxiety symptoms after undergoing the art therapy program between the three cities.

d. The eta-squared and omega-squared values for the overall effects of the independent variable on severity of anxiety symptoms are calculated as follows:

Eta-squared (η^2) = SSB/SST = 340.4/(340.4+506.8) = 0.40

Omega-squared (ω^2) = (SSB - dfB*MSW)/(SST + MSW) = (340.4 - 2*42.23)/(340.4+506.8+42.23) = 0.34

These three strategies can help you understand why the volume of a pyramid is 1/3 lwh.

The formula for the volume of a pyramid is V = 1/3 lwh and the reason why the value is 1/3 is because of the three different strategies that can be used to calculate it.

The first strategy is to dissect a cube (a 3-dimensional rectangle) into the pyramid and the remaining negative space (assuming l=w=h=1). Comparing the volume of the pyramid to the negative space will show that the pyramid takes up 1/3 of the cube.

The second strategy is to stack multiple pyramids together. This will show that the sum of their volumes is equal to one third the total volume of the base they are stacked on.

The third strategy is to slice the pyramid horizontally, and calculate the volume of the four blocks. This will overestimate the volume of the pyramid, but by subtracting this volume from the total volume of the base, you can get a lower limit for the volume of the pyramid.

These three strategies can help you understand why the volume of a pyramid is 1/3 lwh.
