Select the expression equivalent to (-2x + 8.1y) - (-9x + 5.3y).

He can make 4 pancakes with the whole mixture.

Step-by-step explanation:

It is given that,

Jaylen has a total of pancake mixture = 1 liter.

The amount of pancake mixture he uses to make 1 pancake = 1/4 liter.

You need to find the number of pancakes he can make using the 1 liter of pancake mixture.

To find the number of pancakes :

let us take 'N' be the number of pancakes he can make using 1 liter of mixture.

⇒ Total mixture = amount of mixture needed for 1 pancake × N

⇒ 1 liter = 1/4 liter × N

⇒ 1 = N/4

Cross multiply the denominator 4 to the other side, to find N

⇒ 1 × 4 = N

⇒ N = 4 pancakes

Therefore, he can make 4 pancakes with the whole mixture.

Answer: [tex]6x-8[/tex]

Step-by-step explanation:

Let's get rid of the parenthesis' here as they are useless in this equation

[tex]3x+6-4+3x+6-4\\[/tex]

Now we combine like terms

[tex]3x+3x=6x\\6-4+6-4=-8[/tex]

Your answer will be

[tex]6x-8[/tex]

Answer:

El perímetro del triángulo rectángulo es aproximadamente 29.627.

Step-by-step explanation:

Las coordendas de los vértices del triángulo rectángulo son [tex]A(x,y) = (1,-2)[/tex], [tex]B(x,y) = (-8,4)[/tex] y [tex]C(x,y) = (5,2)[/tex]. En primer lugar, determinamos las longitudes de los segmentos AB, BC y AC por el Teorema de Pitágoras:

[tex]AB = \sqrt{(-8-1)^{2}+[4-(-2)]^{2}}[/tex]

[tex]AB \approx 10.817[/tex]

[tex]BC = \sqrt{[5-(-8)]^{2}+(2-4)^{2}}[/tex]

[tex]BC \approx 13.153[/tex]

[tex]AC =\sqrt{(5-1)^{2}+[2-(-2)]^{2}}[/tex]

[tex]AC \approx 5.657[/tex]

El perímetro del triángulo ([tex]p[/tex]) es la suma de todos estos segmentos:

[tex]p = AB + BC + AC[/tex]

[tex]p \approx 29.627[/tex]

El perímetro del triángulo rectángulo es aproximadamente 29.627.

From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.

         Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute

Determining the number of minutes she will have to take in order to reach school,

         Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes

Adding this to the initial time,

           Final time = 8:25 am + 20.52 minutes

                    = 8:45 am and 31.2 seconds.

She will reach the school on time even without increasing her speed.

Both ABC and DEF are right triangles.

Because BC is congruent to EF, two of the corresponding angles of the triangle are congruent.

C is congruent to F

The expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

It is defined as the ratio of the number of favourable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.

Total outcomes = {1, 2, 3, 4, 5, 6]

Total number of outcomes = 6

Favourable outcomes = {5}

Total number of favourable outcomes = 1

Probability of rolling 5 = 1/6

The expected number of 5's would be 30×(1/6) =  5 times

Thus, the expected number of 5's would be rolled is 5 times if the Gavin rolls a fair dice 30 times.

Answer: I am pretty sure that it is true for some cases

Step-by-step explanation:

Answer:

x = 4, y = 5

Step-by-step explanation:

[tex]2x-y=3\\4x-2y=6[/tex]

so:

[tex]4x - 2y = 6\\+ 5x + 2y = 30\\9x= 36\\x=4[/tex]

Substitute this into 2x - y = 3:

[tex]8-y=3\\y = 5[/tex]

3 x 3

You are multiplying 3 by itself , so you have two 3’s.

Exponential form is the number raised to the total numbers:

Answer is 3^2

Answer:

1 inch represents 11 feet.

Step-by-step explanation:

Actual length is 363 feet

Scale model is 33 inches.

So, the scale factor is [tex]\frac{33}{363}[/tex]

Simplify it, we get [tex]\frac{1}{11}[/tex]

It means the scale factor is 1 inch for 11 feet.

That's 1 inch represents 11 feet.

Answer: The answer to your question is 6[tex]\sqrt{3}[/tex]

Step-by-step explanation:

To solve this problem we will use proportions. We will compare the largest right triangle and the medium size triangle.

                          Medium triangle                     Large triangle

hypotenuse                 y                                            9 + 3

adjacent size               9                                               y

- Write the proportions

                                  y/9 = (9 + 3)/y

-Solve for y

                                  y² = 9(12)

                                  y² = 108

                                  y =   [tex]\sqrt{180}[/tex]

-Find the prime factors of 108

                                  108  2

54 2

                                     27 3

                                      9  3

                                      3   3

                                       1

then,       108 = 2² 3³

-Expressthe root as fractional exponents

                                  2²/² 3²/² 3¹/²

-Simplification

                                   2(3)(3)¹/²

-Result

                                      6[tex]\sqrt{3}[/tex]
