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.

Answer:

y= -3x+15.

Step-by-step explanation:

To solve this equation, we first need to calculate the slope of the equation:

m= [tex]\frac{-3-3}{6-4}[/tex] m= [tex]\frac{-6}{2}[/tex] m= -3.

Now, we can simply plug in our slope value into our line equation (y= mx+b) with one of the point listed to find our b value.

3= -3(4)+b

3= -12+b

15=b

Finally, the equation we get is:

y= -3x+15

Answer:

D. 4x + 32; E. 4(x + 8)

Step-by-step explanation:

The correct answer is none. This problem is incorrect. The perimeter of a polygon is the sum of the lengths of all the sides. A perimeter is a length, not an area. A perimeter is expressed in feet, not square feet.

Ignoring the "square feet" part, once again, the perimeter is the sum of the lengths of all sides. Since this is a square, all sides have the same length, and there are 4 sides.

perimeter = 4s

perimeter = 4(x + 8) = 4x + 32

Answer:

-1.8

Step-by-step explanation:

The residual value is -1.8 if the line of the best fit is y = 1.6x - 4 and the actual value is -1 option first is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

The missing data:

The line of the best fit is:

y = 1.6x - 4

When x = 3

Plug x = 3 in the above line equation:

y = 1.6(3) - 4

y = 4.8 - 4

y = 0.8

Now the residual value = actual value - expected value

= -1 -0.8

= -1.8

Thus, the residual value is -1.8 if the line of the best fit is y = 1.6x - 4 and the actual value is -1

Probability of Picking a Purple marble is

[tex]P=\frac{\text{No of Purple marble}}{\text{Total no of marble}}[/tex]

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.

The plumber charges $35 per hour, calculated by dividing the change in total cost ($105) by the change in hours (3).

Explanation:

To find the rate of change in dollars per hour for the plumber's charges, we need to use the definition of rate of change, which is the change in cost divided by the change in time.

Here are the steps for calculation:

This means the plumber charges $35 per hour for their service.

Answer:

x = 2

y = 4

Step-by-step explanation:

Since it gives you the "value" of y, just plug one of them into an equation:

y = x + 2

3x - 2 = x + 2

Now, subtract x from both sides:

3x - 2 = x + 2

-x         - x

__________

2x - 2 = 2

Then, add 2 to both sides:

2x - 2 = 2

    + 2  + 2

________

2x = 4

Finally, divide both sides by 2:

2x = 4

x = 2

Now to get y, just plug in 2 for x in an equation:

y = x + 2

y = 2 + 2

y = 4

Answer:

a = -14

Step-by-step explanation:

Isolate the variable, a. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, divide 5 from both sides:

(5(a + 3))/5 = = (-55)/5

a + 3 = -55/5

a + 3  = -11

Next, fully isolate a by subtracting 3 from both sides:

a + 3 (-3) = -11 (-3)

a = -11 - 3

a = -14

a = -14 is your answer.

Final 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.

Answer:

Part A:

Mean: 129.8

Median: 131.5

Step-by-step explanation:

The mean is the average so we add everything together and then divide it by however many numbers there are. 132 + 141 + 110 + 96 + 154 + 135 + 111 + 139 + 102 + 135 + 133 + 127 + 99 + 124 + 129 + 201 + 131 + 128 + 134 + 135 = 129.8

The median is the number in the middle. That is the number in between the rest from smallest to largest. 96, 99, 102, 110, 111, 124, 127, 128, 129, 131, 132, 133, 134, 135, 135, 135, 139, 141, 154, and 201

The medians are 131 and 132 so we add them together then divide by 2. That gives is 131.5 so that is our answer. I hope this helps and please mark me brainliest!

Answer:

80degrees

Step-by-step explanation:

Find the diagram attached

From the diagram, the opposite angle of the parallelogram are equal hence;

5x= 3x+40

5x - 3x = 40

2x = 40

x = 40/2

x = 20degrees

Also <M + <N = 180

<M + 5x = 180

<M + 5(20) = 180

<M + 100 = 180

<M = 180-100

<M = 80degrees

Hence the measure of angle M is 80degrees

Step-by-step explanation:

For the given parallelogram measure of angle M is 80 degrees.

In the given parallelogram,

Angle N = 5x degree

Angle L  = (3x + 40) degree

Now for parallelogramm

angle L = angle N

⇒  (3x + 40) = 5x

⇒            2x  = 40

⇒               x  = 20

We know that for a parallelogram sum of two consecutive angles = 180 degrees.

    Angle M + angle N = 180 degree

⇒      Angle M + 5(20) = 180 degree

⇒                   Angle M = 80 degree

Hence the measure of angle M is 80 degree.

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 encode the telephone number (555) 265-1431 using the coding matrix [3-37][- 13 5], we match each digit with its corresponding code. First, we look at the area code (555). The code for 5 is 13, so we write it as 13. The codes for 2, 6, and 1 are 3, -13, and 5 respectively, so we write them as 3, -13, and 5. Finally, for the remaining digits (2651431), we encode each digit using the coding matrix. The encoded telephone number is 13-3-7-13-3-5-1-3-5.
