A group of 50 students at a day camp got to choose an activity to do. 22% of students chose to make a craft, 16% chose to play volleyball, and the rest of the students chose to go on a nature walk. How many students chose to go on a nature walk? ​

Answers

Answer:

31 people

Step-by-step explanation:

Total # of people: 50

22% of 50: 0.22 * 50 = 11 people

16% of 50: 0.16 * 50 = 8 people

11 + 8 = 19 people who didn't go on a nature walk

50 - 19 = 31 people who went on a nature walk

what is the inequality shown​

Answers

Answer:

-4 ≤ x ≤ 3

Step-by-step explanation:

Well, we can see that the endpoints land on -4 and 3 and the numbers between -4 and 3 are included. And since the endpoints -4 and 3 have colored dots, they are included as well. Therefore the inequality is -4 ≤ x ≤ 3.

Answer:

-4 ≤ x ≤ 3

Step-by-step explanation:

Because the circles are closed, we know that the inequaily sign will be either "≤" or "≥", meaning that the dotted points are included. Looking at the number line, we can see that the dots lie on points -4 and 3. Because -4 is less than 3, the sign will be a lesser than sign. The line inbetween includes all numbers between -4 and 3.

So, in conclusion, -4 ≤ x ≤ 3 is the inequality shown.

At the end of a baseball game, the players were given the choice of having a bottle of water or a box of juice. Of all of the players, 12 chose a bottle of water, which was 3 4 of the total number of players. Write and solve an equation to determine p. the total number of players at the baseball game. Show your work

Answers

Answer:

p=48

Explenation:

Total number of players = p

According to given scenario:

p - 12 = 3/4p

By simplifying

Taking terms with p on left and constants on right

p - 3/4p = 12

By taking LCM for left side to make denominators same

4/4*p -3/4p = 12

(4p -3p)/4 = 12

1p/4 = 12

Multiplying both sides by 4 we get

p = 12 * 4

p = 48

So total number of players is 48

Answers

The expression x^2 -7x + 10 can be written in factored form as given by Option C: (x-2)(x-5)

How to find the factors of a quadratic expression?

If the given quadratic expression is of the form [tex]ax^2 + bx + c[/tex]

then its factored form is obtained by two numbers alpha( α ) and beta( β) such that:

[tex]b = \alpha + \beta \\ ac =\alpha \times \beta[/tex]

Then writing b in terms of alpha and beta would help us getting common factors out.

Sometimes, it is not possible to find factors easily, so using the quadratic equation formula can help out without any trial and error.

For this case, we're provided the expression:

[tex]x^2 -7x + 10[/tex]

We can write 10 as multiple of -5 and -2 and

we can write -7 as sum of -5 and -2. Thus, we get:

[tex]x^2 -7x + 10 = x^2 -5x - 2x + 10 = x(x-5+ -2(x-5) = (x-2)(x-5)[/tex]

Thus, the expression x^2 -7x + 10 can be written in factored form as given by Option C: (x-2)(x-5)

O You can only multiply B x A if the number of columns of B match the number of rows of A.

Answers

To multiply B and A, the number of columns of B must matc the number of rows of A.

When we can multiply two matrices?

When we multiply two matrices, A and B, we multiply the rows of matrix A by the columns of matrix B.

Now, the number of elements in a row of a matrix, is equal to the number of columns (and the number of elements in a column is equal to the number of rows).

To multiply BxA:

Then, a row on matrix B must have the same number of elements than a column in row A.

Then, to multiply BxA, the number of columns of B must match the number of rows of A, meaning that the correct option is the last one.

neither law can be used
both laws can be used

Answers

The triangle xyz has three sides and three angles

Neither law can be used to solve the triangle

How to determine the appropriate method?

As a general rule, the law of sines states that:

x/sin(X) = y/sin(Y) = z/sin(Z)

As a general rule, the law of cosines states that:

x^2 = y^2 + z^2 - 2yz cos(X)

From the question, we understand that only the angle measures are given.

Kira’s office has two printers. The printing rate of printer 1 is shown in the table. The printing rate of printer 2 is shown in the graph

Indicate which proportional relationship, and explain how the other printer needs to change to become proportional.

Answers

a) The number of pages prints at t=0 is p0=0.
The number of pages prints at t=4 minutes is P1=64 pages.
The first coordinate of the graph is (a, b)=(0, 0).
The second coordinate of the graph is (c, d)=(10 min, 250 pages). The expression for the rate of the pages printed by the first printer is,

r1 = p1 - p0 / 4-0

Substitute the given values in the above expression.

r1 = 64 pages - 0 / 4 minutes - 0
= 16 pages / min

b) Printer 1 prints at an exponential rate. Both the x and y values increase by a constant ratio of 2. We can either use a logarithm of the first printer or find a constant number of documents it can print / time to become proportional.


Find the volume of the cylinder. Use 3.14 for π. Round your answer to the nearest tenth.

Answers

Answer:

Step-by-step explanation:

3 x 3 x 3.14 x 14.5

pie x r^2 x h = V

Answer:

The volume of the cylinder is 410 ft^3

Step-by-step explanation:

To find the volume, we must know the formula. The formula is, V = π r^2 h. We already know that the diameter is 6ft, so we have to cut that in half to get the radius. 6/2 = 3. The radius is 3ft. Now we can plug in the values.

V = π*3^2*14.5

V = π*9*14.5

V = 409.977841

V = 410.0

help pls my education depends on it

Answers

The answer is y = 3x - 2. To find slope, you subtract y2 - y1 and x2 - x1. In this case, y2 - y1 = 10 - 4 and x2 - x1 = 4 - 2. You would result in 6/2, which can be reduced to 3. Your slope is 3, so the first and second answer automatically are eliminated. Next, you could either draw it out on a coordinate plane or just visualize it. The starting point that goes through each line would be -2, which means D, or y = 3x - 2, is the correct answer.

3) cos α ≈ 0.977, cos β ≈ 0.324, cos γ ≈ -0.115. The triangle exists and is obtuse.

How to determine if a triangle may exist and the existence of given angles

Triangles are geometric figures formed by three line segments and internal angles, whose sum is equal to 180°, which can be three acute angles or an obtuse angle and two acute angles or a right angle and two acute angles. The possibility is determined by applying the law of cosine:

[tex]\cos \theta = -\frac{x^{2}-y^{2}-z^{2}}{2\cdot y\cdot z}[/tex]   (1)

The triangle if and only if the cosine of each angle is between -1 and 1 with the following characteristics:

If the cosine of the angle is between 0 and 1, then it is acute.If the cosine of the angle is 0, then it is right.If the cosine of the angle is between 0 and -1, then it is obtuse.

Now we proceed to determine the existence of each triangle:

1) cos α = 0.8, cos β = 0.6, cos γ = 0. The triangle exists and is right.

2) cos α ≈ 0.882, cos β ≈ 0.471, cos γ ≈ 0.441. The triangle exists and is acute.

3) cos α ≈ 0.977, cos β ≈ 0.324, cos γ ≈ -0.115. The triangle exists and is obtuse.

4) cos α = 1, cos β = 1, cos γ = -1. The triangle does not exist.

The directors of a dance show expect many students to participate but don’t yet know how many students will come. The directors need 7 students to work on the technical crew. The rest of the students work on dance routines in groups of 9. For the show to work, they need at least 6 full groups working on dance routines.

Answers

The inequality that represents the scenario given above in terms of the number of students is 9x + 7 ≥ 54

What is the Inequality?

Inequality is known to be a statement that shows the step or order association either it is greater than, equal to, less than, etc., that exist between two or more numbers in an expression.

Note that 7 students are in the technical crew. Denote the number of students in a group as = x

We take the other students in dance routines in groups of 9 as 9x.

Therefore, we say that the total number of students = 9x + 7

Since 6 full groups are working on dance routines, we then multiply by the student dance groups =  9  x  6 = 54

Therefore, we can state that our inequality as:

9x + 7 ≥ 54

Then you collect like terms:

9x ≥ 54 - 7

9x ≥ 47

x ≥ 47/9

x ≥ 6

So therefore, I will write to  directors that the number of students they need in each group should be at least 6 students.
