what is the product of (2.5+y) and (1.1y)

Answers

Answer 1

The product of the expressions (2.5 + y) and (1.1y) will be 2.75y + 1.1y².

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

The expressions are given below.

(2.5 + y) and (1.1y)

Then the product of the expressions (2.5 + y) and (1.1y) will be

⇒ (2.5 + y) × (1.1y)

⇒ 2.75y + 1.1y²

The product of the expressions (2.5 + y) and (1.1y) will be 2.75y + 1.1y².

In the diagram, what is the ratio of patterned circles to plain circles?
Four arrays of circles are represented. First array has a plain circle. Second array has 4 patterned circles and 1 plain circle. Third array has 1 patterned circle and 4 plain circles. Fourth array has a plain circle.

Answers

The ratio of the patterned circles to plain circles is 6 : 7.

We are given the four arrays of the circles.

In the first array, we have only 1 plain circle.

In the second array, we have 4 patterned circles and 1 plain circle.

In the third array, we have 1 patterned circle and 4 plain circles.

In the fourth array, we have only 1 plain circle.

So, total patterned circles = 5 + 1

Total patterned circles = 6

Total plain circles = 1 + 1 + 4 + 1

Total plain circles = 7

Ratio of patterned circles to plain circles will be given as:

6 : 7

Therefore, we get that, ratio of the patterned circles to plain circles is 6 : 7.

Work out an expression for the nth term




Please please answers this question ill give u like and mark as brainlist

Answers

Answer:

2n² + n

Step-by-step explanation:

Given sequence:

3, 10, 21, 36, ...

Work out the first differences between terms:

[tex]3 \underset{+7}{\longrightarrow} 10 \underset{+11}{\longrightarrow} 21 \underset{+15}{\longrightarrow} 36[/tex]

As the first differences are not the same, work out the second differences.

[tex]7 \underset{+4}{\longrightarrow} 11 \underset{+4}{\longrightarrow} 15[/tex]

As the second differences are the same, the sequence is quadratic and will contain an n² term.

The coefficient of n² is always half of the second difference. Therefore, as the second difference is 4, the coefficient of n² is 2.

To work out the nth term of the sequence, write out the numbers in the sequence 2n² and compare with the given sequence:

[tex]\begin{array}{|l|c|c|c|c|}\cline{1-5} n & 1 & 2 & 3 & 4 \\\cline{1-5} 2n^2 & 2 & 8 & 18 & 32\\\cline{1-5} \sf Operation & +1 & +2& +3& +4\\\cline{1-5} \sf Sequence & 3 & 10 & 21 & 36\\\cline{1-5}\end{array}[/tex]

Therefore, we need to add n to 2n² to match the sequence.

Therefore, the nth term of this sequence is 2n² + n.

Answers

The measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°

Complement of an Angle

From the question, we are to determine the complement of the given angle measure

From the given information, the measure of angle K (m ∠K) is (6x + 12)°

NOTE: If two angles are complementary, the measures of the angles sum up to 90°

Let the complement of angle K be angle L.

Thus,

∠K + ∠L = 90°

(6x + 12)° + ∠L = 90°

6x° + 12° + ∠L = 90°

∠L = 90° - 12° - 6x°

∠L = 78° - 6x°

∠L = (78 - 6x)°

Hence, the measure of the complement of angle K is (78 - 6x)°. The correct option is D. (78 − 6x)°

2,100 product labels in three months. The number of labels collected in the
first two months was three times the number of labels collected in the thirc
month. How many product labels were collected in the third month?

Answers

The total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.

Let the number of labels collected in the first two months be 3 x.

We are given that the number of labels collected in the first two months was three times the number of labels collected in the third month.

So, the number of labels collected in the third month = 3 x / 3 = x

Now, we are also given that:

The total number of labels collected by the students at the school = 2100.

So, we get the equation as:

3 x + x = 2100

4 x = 2100

x = 2100 / 4

x = 525 labels.

Therefore, we get that, the total number of labels collected by the students in the third month is equal to 525 by the equation 3 x + x = 2100.

What is the solution for item 1?

The situation is modeled by the following linear function:

P(n) = 2.75 + 4.25n.

We have that P(n) = 24, hence we have to solve for n.

24 = 2.75 + 4.25n.

n = (24 - 2.75)/4.25

n = 5.

She played 5 games.

What is the solution for item 2?

The situation is modeled by the following system of equations:

x = 3y.x + y = 28.

Hence:

3y + y = 28

4y = 28

y = 7.

Gary had 7 rebounds.

What is the solution for item 3?

Considering the equations for the perimeter of the triangle, and the situation described, we have that:

l = 2w - 4.2(l + w) = 220.

Hence:

2(2w - 4 + w) = 220

2(3w - 4) = 220

3w - 4 = 110

3w = 114

w = 114/3

w = 38.

The width of the rectangle is of 38 inches.

What is the solution for item 4?

Solution x for item 2, hence:

x = 3y = 3 x 7 = 21.

Mark had 21 rebounds.

What is the solution for item 5?

This situation is modeled by the following equation:

3x + 5 = 140

3x = 135

x = 135/3

x = 45.

Tony spent 45 minutes studying for his Biology test.

What is the solution for item 6?

This is the solution for l of item 3, hence:

l = 2w - 4 = 2 x 38 - 4 = 72.

The length of the rectangle is of 72 inches.

What is the solution for item 7?

The situation is modeled by the following equation:

P(x) = 125 + 50x.

We have that P(x) = 425, hence we solve for x as follows:

425 = 125 + 50x

50x = 300

x = 300/50

x = 6.

He rented the limousine for 6 hours.

What is the solution for item 8?

The situation is modeled by the following system:

x + y = 37.x = 15 + y.

Hence:

15 + y + y = 37

2y = 22

y = 11.

x = 15 + 11 = 26.

The two numbers are 11 and 26.

What is the solution for item 9?

The situation is modeled by the following system:

y = x - 7.x + 6 = 2(y + 6).

Hence:

x + 6 = 2(x - 7 + 6)

x + 6 = 2(x - 1)

x + 6 = 2x - 2

x = 8.

What are inequalities?

Inequalities are mathematical expressions having both sides unequal or rather not equivalent to each other.

Given the inequality;

4x (x+3) < -24

First, expand the bracket

4x² + 12x < -  24

Let's turn to quadratic inequality

4x² + 12x - 24 < 0

Factorize further

4 ( x² + 3x - 4) < 0

4 ( x² + 4x - x - 4) < 0

4 ( x(x + 4) - 1 (x + 4) ) < 0

4(x - 1) ( x + 4) < 0

expand the bracket

4x - 4 < 0

x < 1

And

x < -4
