Answer: 2.7 hours

Step-by-step explanation:

Hi, to answer this question we simply have to calculate the amount of time that takes making one batch of dinner rolls, by adding the individual times of, kneading, resting and baking.  

Mathematically speaking  

0.7 hours +1.6 hours +0.4 hours = 2.7 hours  

It takes 2.7 hours to make each batch of dinner rolls.

The ball costs $0.05 and the bat costs $1.05. We derived these amounts by setting up an equation based on the given information that the total cost is $1.10 and the bat costs $1 more than the ball, then solving for the ball's price.

To answer the classic problem about the cost of a bat and ball, let's denote the cost of the ball as 'x' dollars. Since the bat costs $1 more than the ball, the cost of the bat is 'x + $1.00'. The total cost is $1.10, and we know the sum of the bat and ball together is:

x + (x + $1.00) = $1.10

To find the value of x, solve the equation:

2x + $1.00 = $1.10

Subtract $1.00 from both sides to isolate the term with x:

2x = $0.10

Divide both sides by 2 to find the cost of one ball:

x = $0.05

So, the ball costs $0.05 and the bat costs $1.05 since it's $1.00 more expensive than the ball.

Step-by-step explanation:

To know the number of rows of the beads are used on the bookmark, we just need to divide.

Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.

We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.

Then, the division is

[tex]\frac{200mm}{4mm} =50[/tex]

Therefore, there are 50 beads on the bookmark.

51 rows of beads are used on the bookmark.

To determine the number of rows of beads on the bookmark, we need to follow these steps:

 1. Convert the length of the bookmark from centimeters to millimeters to match the unit of measurement for the spacing between rows of beads. Since there are 10 millimeters in a centimeter, the bookmark is [tex]\( 20 \text{ cm} \times \frac{10 \text{ mm}}{1 \text{ cm}} = 200 \text{ mm} \)[/tex]  long.

2. Determine the distance between each row of beads. The problem states that there is a row of beads every 4 millimeters.

3. Calculate the number of intervals between the beads along the bookmark. To do this, divide the total length of the bookmark by the spacing between each row of beads: [tex]\( \frac{200 \text{ mm}}{4 \text{ mm/row}} = 50 \) intervals.[/tex]

4. Since we have an interval at each end of the bookmark where a row of beads is placed, we already have two rows of beads. For each interval between these end rows, there is an additional row of beads. Therefore, we have one more row of beads than the number of intervals.

5. Add one to the number of intervals to account for the starting row of beads: [tex]\( 50 \text{ intervals} + 1 = 51 \)[/tex] rows of beads.

Thus, there are 51 rows of beads used on the bookmark.

Answer:

y=43

Step-by-step explanation:

y=x+10

y=33+10

y=43

To find the value of y when x=33, knowing that x and y are directly proportional, we first calculate the proportionality constant from the given values and apply it to find y=88 when x=33.

The task is to find the value of y when x is given, knowing that x and y are directly proportional. Thus, we first find the proportionality constant using the given values of x=6 and y=16. The formula for direct proportionality is y = kx, where k is the proportionality constant. Solving for k we get k = y/x => k = 16/6. Once we have the value of k, we can find y for x=33 by rearranging the formula to y = (16/6) * 33.

After performing the calculation, we find:

Therefore, y is 88 when x is 33, as they are directly proportional.

Answer:

Step-by-step explanation:

Just took it. I selected your answer and got it wrong. Here is my answer.

The correct option is F q(x) = (9x - 4)(x – 4)  is equivalent to q(x) = 9x² – 24x + 16.

To find the equivalent function for q(x) = 9x² – 24x + 16. we need to factor the quadratic equation.

We are looking for two binomials that when multiplied together will give us the original quadratic equation.

In this case, a = 9, b = -24, and c = 16.

We need to find two numbers that multiply to give ac (which is 9 * 16 = 144) and add to give b (which is -24).

The two numbers that satisfy these conditions are -12 and -12 because (-12) * (-12) = 144 and (-12) + (-12) = -24.

Now we can rewrite the middle term of the quadratic equation using these two numbers:

 q(x) = 9x² – 24x + 16.

Next, we group the terms:

q(x) = (9x² – 12x) - (12x - 16)

Now we factor out the common factors from each group:

 q(x) = 3x(3x - 4) - 4(3x - 4)

We can see that (3x - 4) is a common factor

q(x) = (3x - 4)(3x - 4)

However, we need to be careful here because we have a common factor of 3 in both binomials.

We can factor this out to get the correct factored form:

q(x) = (9x - 4)(x - 4)

This matches option F.

This is the original quadratic equation, confirming that option F is indeed the correct answer.

To find the probability that the numbers on the orange and aqua spinners will add to 5 or more, determine the favorable and total outcomes. The probability is 11/36.

Explanation:

To find the probability that the numbers on the orange and aqua spinners will add to 5 or more, we need to determine the favorable outcomes and the total possible outcomes. Let's say the orange spinner has numbers 1 to 6, and the aqua spinner also has numbers 1 to 6. To get a sum of 5 or more, we can have the following outcomes:

Orange spinner: 1, Aqua spinner: 5 or 6

Orange spinner: 2, Aqua spinner: 4, 5, or 6

Orange spinner: 3, Aqua spinner: 3, 4, 5, or 6

Orange spinner: 4, Aqua spinner: 2, 3, 4, 5, or 6

Orange spinner: 5 or 6, Aqua spinner: 1, 2, 3, 4, 5, or 6

These are a total of 11 favorable outcomes. The total possible outcomes are 6 ×6 = 36, since each spinner has 6 numbers. Therefore, the probability of getting a sum of 5 or more is 11/36.

Got 3.2 from Second length is twice the third so we divide by 2 + 1 = 3

0.2 is from 1/5 = 0.2

3 is the third length

30 is second length and 15 is the first.

Step-by-step explanation:

The question relates to solving a simple algebraic equation. The first length of rope is identified as 15 feet. Consequently, the third piece, which is a fifth of the first length, is 3 feet.

We can solve this problem by first setting up an equation using the information given in the problem. Let's call the first length of rope x. Then according to the problem, the second length is twice the first length, or 2x, and the third length is one-fifth of the first length, or x/5. So, the total length of the rope is x + 2x + x/5 = 48.

First, we have to combine like terms on the left side to get 3x +(1/5)x equal to 48. If we multiply every term in the equation by 5 to clear out the fraction, we get 15x + x = 240. Combined, we have 16x equal to 240. Finally, we divide each side by 16 to solve for x. This gives us x equal to 15.

So, the third length, which is one-fifth of the first length, would be 15 divided by 5, which equals 3. Therefore, the third length of the rope is 3 feet.

Answer:

192 total ways

Step-by-step explanation:

This time, we have already 2 selected kings, therefore we must find the remaining 3 cards.

There are two general ways to do this:

Case 1: you draw two of some other matching cards and another king

Case 1 - K + X + X where K is a King and X is some other card than a King. So there are 2 Ks to draw. Then there are 12 other cards that are not from the king, and since you get two of them it would be 2 taken from 4:

4C2 = 4! / (2! * (4-2)!) = 6

Therefore there are 6 different arrangements of the two.

So 2 * 12 * 6 = 144 total ways to do this.

Case 2: you draw three of some other matching cards

Case 2 - X + X + X where the Xs are all non-king cards. So 12 cards to choose from, and then calculate 3 taken from 4:

4C3 = 4! / (3! * (4-3)!) = 4

Therefore there are 4 different arrangements of the three. So 12 * 4 = 48 total ways to do this.

Which means that:

144 + 48 = 192

There are 192 total ways to get a full house when you start with two kings.

Answer:

6wz

Step-by-step explanation:

z is not part of 18w, so it's not one of the factors for both 18w and 30wz

From the options provided, the factor '6wz' is not a common factor of 18w and 30wz because no such term exists in the factorization of the expression 18w.

The common factors of 18w and 30wz can be determined by breaking down each expression into its unique factors. For 18w, the factors are 2, 3, 3, and w. For 30wz, the factors are 2, 3, 5, w, and z. The common factors between the two expressions are 2, 3, and w.

From the options provided (3w, 6, 6wz, w) - we can see that 3w and w are indeed common factors of both 18w and 30wz. The number 6 is also a common factor as it can be achieved by multiplying 2 and 3, which are present in both expressions.

However, 6wz is not a common factor. Although the '6', 'w' and 'z' parts are contained within 18w and 30wz separately, the combination of '6wz' cannot be made using the factors of 18w since the term 'z' is not included in its factors.

To calculate the radius(r) from the semicircle's perimeter(P), we rearrange the formula P = πr + 2r to r = P / (π + 2). Substituting 15.42 for P, the radius is approximately 3 kilometers.

The subject of this question is Mathematics, specifically geometry and the concept of a semicircle's perimeter. To find the radius of a semicircle with given perimeter (P), we need to use the formula for perimeter of a semicircle which is P = πr + 2r, where r is the radius. Here, P = 15.42 kilometers.

First, we will rearrange the formula to isolate r: r = P / (π + 2). Now, substituting into the formula with the given perimeter, we get r = 15.42 / (π + 2) ≈ 15.42 / 5.14 ≈ 3 km (rounded to nearest whole number).

This means the radius of the semicircle is approximately 3 kilometers.
