how manh solutions does the system have​

Answer: Cells typically communicate using chemical signals. These chemical signals, which are proteins or other molecules produced by a sending cell, are often secreted from the cell and released into the extracellular space. There, they can float – like messages in a bottle – over to neighboring cells.

Answer:

12

Step-by-step explanation:

Multiply 2/3 and 18. Since it a whole number, convert it to a fraction by putting it over a denominator of 1. When multiplying fractions, calculate numerator times numerator, then denominator times denominator. Multiply 2/3 x 18/1 to get 36/3.

Simplify the resulting fraction as needed by dividing it by the common denominator. The common denominator of 36 and 3 is 3. Diving 36 and 3 by 3 gives you a fraction of 12/1, which is the same as 12. Thus, two-thirds of 18 is 12.

[tex]\frac{2}{3}*\frac{18}{1}[/tex]

[tex]=\frac{36}{3}[/tex]

[tex]=\frac{12}{1}[/tex]

[tex]=12[/tex]

Answer:

3.4

Step-by-step explanation:

Step 1: Multiply the whole number by the denominator

3 x 5 = 15

Step 2: Add the result of step 1 to the numerator

15 + 2 = 17

Step 3: Divide the result of step 2 by the denominator

17 ÷ 5 = 3.4

Answer:

No

Step-by-step explanation:

Equations with direct variation follow the form y= kx, where k = constant of proportionality.

To find out if y + x = 1, we need to isolate y by itself.

Step 1: Subtract x from both sides.

As you can see, y + x = 1 does not show direct variation.

Answer:

25%

Step-by-step explanation:

Total number of drawings: 59

Drawing a pineapple chew: 15

p(pineapple chew) = 15/59 = 0.2542 = 25%

Using it's concept, it is found that there is a 25% probability that the next chew Elijah removes from the bag will be pineapple chew.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem, the experiment was performed 59 times, and 15 of them resulted in a pineapple being selected, hence the probability is given by:

p = 15/59 = 0.25 = 25%.

Answer: A

Step-by-step explanation:

You can solve a system of equations by graphing, elimination, substitution, or using a combination. The graph of a linear equation is a line. The point(s) where one line intersects another is the solution to the system. Therefore, since Lucy found that the lines intersected at the point (-4, 1), it is the solution to the system of linear equations

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is [tex]\rm M = log\left ( \dfrac{10S}{S}\right )[/tex].

Given

The magnitude, M, of an earthquake is defined to be M = log StartFraction I Over S EndFraction, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a "standard" earthquake, which is barely detectable.

The magnitude of an earthquake is a measure of the energy it releases.

For an earthquake with 1,000 times more intense than a standard earthquake.

The equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is;

[tex]\rm M =log \dfrac{I}{S}\\\\M = log \dfrac{10s}{s}\\\\M=log 10\\\\M =1[/tex]

Hence, the equation represents the magnitude of an earthquake that is 10 times more intense than a standard earthquake is [tex]\rm M = log\left ( \dfrac{10S}{S}\right )[/tex].

Before we find the area of the triangle, we need to know the base, which is the diameter of the semi-circle.

Now, let's find the area of the triangle.

The area of the figure is basically the sum of the semi-circle and the triangle.

Thus, the area of the figure is 26.13 ft².
