Can you please help me understand how to solve a trig ratio like this?

Answer:

The distance travelled was 314 inches.

Step-by-step explanation:

In order to calculate the distance that the unicycle will travel in 4 revolutions we first need to know the length of it's wheel, this is calculated by using the formula bellow:

length = 2*pi*r

Where r is the radius of the wheel that is equal to r = d/2

length = 2*pi*(d/2) = 2*3.14*(25/2) = 3.14*25 = 78.5 inches

If the wheel made 4 complete revolutions then the distance travelled was 4 times the length of it's wheels. We have:

distance = 4*length = 4*78.5 = 314 inches

The distance travelled was 314 inches.

To find the total amount of money Gavin and Jim got all together, we need to solve the equation 5x = x + £39, where x represents the amount Jim received. The total amount is £58.50.

Explanation:

To find the total amount of money that Gavin and Jim got altogether, we need to first determine the amounts they each received. Let's say the amount Jim received is represented as 'x'. According to the ratio of 5:2, Gavin received 5 times the amount Jim received, so Gavin received 5x.

We're given that Gavin gets £39 more than Jim, so we can set up the equation: 5x = x + £39. Simplifying this equation, we get 4x = £39. Dividing both sides by 4, we find that x = £9.75.

Now, we can calculate the total amount they got altogether by adding the amounts Jim and Gavin received: £9.75 + 5(£9.75) = £9.75 + £48.75 = £58.50.

Answer: 24 nickels

Step-by-step explanation:

1. n= nickels

q=quarters

2. n+q=39

.05n+.25q=4.95

3. n=39-q (Replace n with what n is equal to in the other equation) .05(39-q)+.25q=4.95

4. Solve for q: (.05x39)+(.05x-q)+.25q=4.95

5. 1.95-.05q+.25q=4.95 (Combine like terms)

6. 1.95+(-.05q+.25q)=4.95

7. 1.95+0.2q=4.95

8. Move 1.95 to the other side of equal sign by subtracting it from both sides. 0.2q=3

3/0.2= 15... so quarters=15

So if you look back at the other equation it says n+q=39. So, 39-15=24. There is 24 nickels.

Answer: His baseball cards can be represented as 0.8 of the entire collection

Step-by-step explanation: Castor has 40 baseball cards and 10 football cards. Therefore his total number of cards is given as 40 + 10 which is 50.

The fraction of his cards which are baseball cards only is calculated as

Baseball cards = 40/50

Baseball cards = 4/5

Converting 4/5 to a decimal (which can equally be done with a calculator) gives you 0.8

Hence, the part of his entire card collection that can be represented by baseball cards is 0.8

Solution of the equation is x = -18

An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

Given equation,

(2/3)x = -12

Multiplying with 3 on both sides,

3×(2/3)x = -12×3

2x = -36

Dividing by 2 on both sides

2x/2 = -36/2

x = -18

Hence, x = -18 is the solution of the equation.

Given:

The radius of the cone = 14 ft

The slant height of the cone = 27 ft

To find the lateral surface area and the total surface area of the given cone.

Formula

The lateral surface area of the cone is

[tex]LSA = \pi rl[/tex] and

The total surface area of the cone is

[tex]TSA = \pi r^{2} + \pi r l[/tex]

where,

r be the radius and

l be the slant height of the cone.

Now

Taking r = 14 and l = 27 we get

[tex]LSA = \pi (14)(27)[/tex] sq ft

or, [tex]LSA = 1187.5[/tex] sq ft

Again,

[tex]TSA = \pi(14^2)+\pi (14)(27)[/tex] sq ft

or,[tex]TSA = 1803.3[/tex] sq ft

Hence,

The lateral surface area of the cone is 1187.5 sq ft and the total surface area of the cone is 1803.3 sq ft. Option C.

Final answer:

To find the number of rides that you went on at the fair given the total cost, $26, and the cost per ride, $3, you can use the equation $26 = $5 + $3r. Solving for r, you find that you went on 7 rides.

Explanation:

To write an equation that shows the number of rides, r, that you went on, we need to consider the total cost you spent and the cost per ride.

The cost to enter the fair is $5, and for every ride you go on, it costs $3. So, the equation would be:

Total Cost = Cost to Enter + Cost per Ride x Number of Rides

In this case, you spent a total of $26. Plugging in the values, we get:

$26 = $5 + $3r

Now, we can solve for r by isolating the variable:

$26 - $5 = $3r

$21 = $3r

To find the number of rides, divide both sides by $3:

r = $21/$3

r = 7

Therefore, you went on 7 rides at the fair.

Answer:

The third answer

Step-by-step explanation:

(side note: You probably need to use a calculator that can calculate pi)

The formula to find the area of a circle is pi r squared.

In this case, pi times r squared is 19.63495....... continued

This is probably going to be rounded

so... 19.63

For all of the circles, this is multiplied by 4.

This is 78.52

The area of the square is 100 cm since 10 times 10 is 100

You take 100 cm and then subtract it by 78.54

Voila! now you have 21.46

Box A, weighing 212.04 kilograms, is 0.04 kilograms heavier than Box B, which weighs 212 kilograms. The difference in weight is due to differing volume and density.

The question is asking us to compare the weight of two boxes, Box A and Box B. Box A weighs 212.04 kilograms and Box B weighs 212 kilograms. To compare the weights, we subtract the weight of Box B from that of Box A: 212.04 kg - 212 kg = 0.04 kg. Therefore, the correct statement is: Box A weighs 0.04 of a kilogram more than Box B.

This question measures your understanding of decimal numbers and weight comparison in the metric system, specifically kilograms. In other words, 1 kilogram of one substance is equal in weight to 1 kilogram of another substance. It's the volume and density that might differ between them.
