Which expression represents the amount of money John has collected?

John collects $5 for club dues from each member. Use the variable
m
for the number of members in the club.

Answer:

The equation to find the total cost for buying x shirts would be y = 11x + 30

Step-by-step explanation:

The equation y = 11x + 30 represents the total cost of buying x jerseys, where x is the number of jerseys and y is the total cost. The $11 represents the cost of each jersey and the $30 is the one-time fee for the design. So, for every jersey purchased, the cost goes up by $11, and the $30 fee is added on top of that.

r = red tiles

b = blue tiles

b = r + 12 , whatever "r" is, "b" is 12 more than that

[tex]\stackrel{red}{3}~~ : ~~\stackrel{blue}{5}\qquad \implies \cfrac{r}{b}=\cfrac{3}{5}\implies \cfrac{r}{r+12}=\cfrac{3}{5}\implies 5r=3r+36 \\\\\\ 2r=36\implies r=\cfrac{36}{2}\implies r=18[/tex]

Answer:

18

Step-by-step explanation:

Because there are 12 more blue tiles than red, that means that we can write the equation 3x + 12 = 5x. By simplifying, the equation is boiled down to 12=2x. By dividing, we see that x=6. This means that we can multiply 3 by 6 to get 18 red tiles. To check our answer, we just multiply 6 by 5 to get 30, and the ratio 18:30 is equivalent to 3:5. Also, 30-18=12, so this must be correct.

The pitch of the roof is roughly 35.3 degrees, and the middle height of the roof is 19.3 feet.

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship in Euclidean geometry between the three sides of a right triangle. It indicates that the area of the hypotenuse square is equal to the sum of the areas of the squares on the other two sides.

Here,

To find the pitch of the roof, we need to use the Pythagorean theorem to determine the height of the roof at the center. The Pythagorean theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the longest side (the hypotenuse).

In this case, the height of the roof at the center is the hypotenuse, and the two shorter sides are the width of the house (32 feet) and half of the length of the rafter (22 feet / 2 = 11 feet). So, using the Pythagorean theorem, we can set up the following equation:

h² = (32 / 2)² + 11²

h² = 16² + 11²

h² = 256 + 121

h² = 377

h = √377

h = 19.3 feet

Next, we use the tangent function to find the pitch of the roof. The tangent of an angle is equal to the opposite side divided by the adjacent side. In this case, the opposite side is the height of the roof (19.3 feet), and the adjacent side is half of the rafter length (11 feet). So, we can set up the following equation:

tan(pitch) = 19.3 / 11

We can use the inverse tangent function (tan^-1) to find the angle, which will give us the pitch of the roof in degrees.

pitch = tan^-1(19.3 / 11)

The pitch of the roof is approximately 35.3 degrees and height of the roof at the center is 19.3 feet.

Answer:

we can find a + a^(1/2) by substitution:

a + a^(1/2) = 6/5 + √(6/5)

Step-by-step explanation:

We have the equation:

a² + a - 1/2 = 5

Adding 1/2 to both sides:

a² + a = 5 1/2

Factoring out a from the left-hand side:

a(a + 1) = 5 1/2

Taking the square root of both sides:

a + 1/2 = ±√(5 1/2 / a)

Since a^(1/2) - a^(1/2) > 0, we know that a is positive, so we can discard the negative root. Then we have:

a + 1/2 = √(5 1/2 / a)

Squaring both sides:

a² + a + 1/4 = 5 1/2 / a

Substituting the expression for a² + a from the first equation:

5 1/2 - 1/2 + 1/4 = 5 1/2 / a

Multiplying both sides by a:

5 1/2 a - 1/2 a + 1/4 a = 5 1/2

Simplifying:

5a - 1/2 = 5 1/2

Adding 1/2 to both sides:

5a = 6

Dividing by 5:

a = 6/5

Finally, we can find a + a^(1/2) by substitution:

a + a^(1/2) = 6/5 + √(6/5)

Answer:

4 middle carriages have 162 passengers

Step-by-step explanation:

Since every 10 consecutive carriages have 398 passengers, then each carriage has 398/10 = 39.8 passengers.

Since there are 36 carriages in the train, then there are 36 * 39.8 = 1428 passengers in the train.

Therefore, there are 1400 - 1428 = -28 passengers missing.

This means that each carriage has 39.8 - (-28/36) = 39.8 + 0.78 = 40.58 passengers.

So, the 4 middle carriages have 4 * 40.58 = 162.32 passengers.

Rounding to the nearest whole number, we can say that 4 middle carriages have 162 passengers.

Answer:

  192

Step-by-step explanation:

If a train with 36 carriages holds 1400 passengers, 398 in any 10 consecutive carriages, you want to know the number in the 4 middle carriages.

The first 30 carriages will hold 3·398 = 1194 passengers, so there must be 1400 -1194 = 206 in the remaining 6 carriages. The same would be true counting carriages from the other end.

Then the 10 +6 carriages at either end of the train must hold 398 +206 = 604 passengers. That leaves 1400 -2·604 = 192 passengers in the middle 4 carriages.

The probability you expect the spinner to not land on B is 0.4.

Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.

We know that, probability of an event = Number of favourable outcomes/Total number of outcomes

Given that, a spinner is divided into three equal parts A, B, and C.

The repeated experiment of spinning the spinner twice is simulated 125 times.

The total number of outcomes = 125

The number of favorable outcomes = 12+18+15+17+13= 75

Probability of landing on B = 75/125

= 0.6

Probability of not landing on B

= 1-0.6

= 0.4

Therefore, the probability you expect the spinner to not land on B is 0.4.

The inverse function can be written as:

g(x) = (x - 7 + √3) / 5

Step-by-step explanation:

Starting with the equation y = 5x + 7 - √3, we switch the roles of x and y to get x = 5y + 7 - √3.

Next, we isolate y by subtracting 7 and adding √3 to both sides, which gives x - 7 + √3 = 5y.

Finally, we divide both sides by 5 to get g(x) = (x - 7 + √3) / 5.

This is the inverse function g(x) of f(x) = 5x + 7 - √3. The inverse function is useful in solving problems where the original function is not explicitly invertible.

If the current is 2.2 A, it falls within the 2% tolerance range of 2.156 A to 2.244 A and would be considered correct.

To determine if 2.2 A falls within the 2% tolerance range, we first need to establish what the expected current value is. If the expected current value is not specified, it's best to use the maximum rated current value as the expected value.

Once we have the expected current value, we can calculate the tolerance range. Tolerance is expressed as a percentage of the expected value, and in this case, it's 2%.

So the tolerance range is:

(Expected Value) * (Tolerance Percentage) = Tolerance Range

For example, if the expected value is 2.2 A, then the tolerance range would be:

2.2  * 0.02 = 0.044

The tolerance range represents the amount by which the actual current can deviate from the expected value and still be considered acceptable. In this case, the tolerance range is 0.044 A, so the acceptable range for the current would be:

(Expected Value - Tolerance Range) to (Expected Value + Tolerance Range)

2.2 - 0.044 to 2.2 + 0.044 = 2.156 to 2.244

Since 6100 is greater than 5600, nine refrigerators and eight pianos would overload the truck.

What is linear inequality?

A linear inequality is an equation that represents a linear relationship between two variables and is used to describe a region of the coordinate plane that satisfies a given set of conditions.

Let "x" be the number of refrigerators and "y" be the number of pianos. The total weight of the refrigerators is 300 pounds per refrigerator, so the total weight of the refrigerators is 300x pounds. The total weight of the pianos is 425 pounds per piano, so the total weight of the pianos is 425y pounds. The total weight of the load must be less than or equal to 5600 pounds, so we can write an inequality as follows:

300x + 425y ≤ 5600

To graph this inequality, we can use the coordinates of points that satisfy the inequality and shade the region that represents the solutions.

To determine if nine refrigerators and eight pianos would overload the truck, we can substitute these values into the inequality and see if it still holds:

300 × 9 + 425 × 8 = 2700 + 3400 = 6100

Since 6100 is greater than 5600, nine refrigerators and eight pianos would overload the truck.

Using trigonometry formulas, the value of tan(x-y) = -16/63

In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. Trigonometry has a wide variety of identities. In order to simplify an expression, identify a more practical version of an expression, or solve an equation, trigonometric identities are frequently employed to rewrite trigonometrical expressions.

Given

cot y = 4/3

1/tan y = 4/3

Cross multiply

tan y = 3/4

Also since csc x = 13/5

1/sin x = 13/5

sin x = 5/13

Since sin x = opp/hyp

opp = 5

hyp = 13

Get the adjacent

hyp² = opp²+adj²

13² = 5²+adj²

adj² = 13² - 5²

adj² = 169 - 25

adj² = 144

adj = 12

cos x = adj/hyp

cos x = 12/13

tan x = sin x/ cos x

tan x = (5/13)/(12/13)

tan x = 5/13 * 13/12

tan x = 5/12

tan(x-y) = tan x - tan y/1 + tan x * tan y

tan(x-y) = (5/12 - 3/4) / 1 + (5/12) (3/4)

tan(x-y) = (5-9/12) / 1 + 5/16

tan(x-y) = -4/12/(21/16)

We subtract 8 from the x-coordinate and add 20 to the y-coordinate of the original point.

In mathematics, translation refers to the process of moving an object from one location to another, without rotating or scaling it. The movement is described by a vector, which is a directed line segment that specifies the direction and distance of the movement.

In two-dimensional geometry, a translation can be represented by a shift of an object along the x- and y-axes. For example, if a point is translated by a vector (a, b), its new position will be (x + a, y + b), where (x, y) is the original position of the point.

Translations can also be performed on shapes, such as lines, polygons, or curves. The effect of a translation on a shape is to create a new shape that is identical to the original shape, but located in a different position.

A translation is a transformation that moves a figure in a certain direction and by a certain distance without rotating or reflecting it. To find the rule for a translation, we need to find the vector that represents the displacement between the original point and the translated point.

Given two points A (2, -5) and A' (-6, 15), the translation vector is given by:

Translation vector = A' - A = (-6, 15) - (2, -5) = (-6 - 2, 15 - (-5)) = (-8, 20)

So, the rule for the translation is:

(x, y) -> (x - 8, y + 20)

This means that to apply the translation, we subtract 8 from the x-coordinate and add 20 to the y-coordinate of the original point.
