Answer:

Step-by-step explanation:

So we have 6x4-5x2+12x2-10

So we are going to add same elements

-5x2+12x2=7x2

so now we have

6x4 +7x2-10

Let u=x2

6u2+7u-10

Now we factor

(6u-5)(u+2)

Replace x2 for u

(6x2-5)(x2+2)

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.

When the sum of two angles is equal to 90 degrees, they are called complementary angles.

Given that;

Since ∠CDA is a right triangle, the sum of ∠ADB and ∠CDB sums up to 90 degrees.

∠ADB + ∠CDB = 90°

(7x +2) + (3x - 2) = 90

Solve for x

7x +2 + 3x - 2 = 90

7x + 3x - 2 +2 = 90

10x = 90

x = 90/10

x = 9

Now, the numerical measure of angle CDB will be;

m∠CDB = (3x - 2)

Plug in x=9

m∠CDB = 3(9) - 2

m∠CDB = 27 - 2

m∠CDB = 25 degrees

Given that ∠ADB and ∠CDB are complimentary angles, the numerical measure of angle CDB is 25 degrees.

One year from now, there are 300 freshmen, 1425 sophomores, 1375 students that transferred out, and 3900 students graduated.

Each category is based on the percentages given, 25% of students transfer, 15% have to repeat the year, and 60% complete the year and the fact that once a student has transferred or graduated they have a 100% chance of staying classified that way.

Percentage, which was adapted from the Latin word "per centum", which means "by the hundred", is a fraction or a ratio in which the value of whole is always 100. It is represented by the symbol "%".

If currently there are 2,000 freshmen, 1,500 sophomores, 500 students that have transferred, and 3,000 graduates,

Among the 2000 freshmen, 25% of students transfer, 15% have to repeat the year, and 60% complete the year.

students who transfer = 25% of 2000 = 500

freshmen(repeater) = 15% of 2000 = 300

sophomore = 60% of 2000 = 1200

Among the 1,500 sophomores, 25% of students transfer, 15% have to repeat the year, and 60% complete the year.

students who transfer = 25% of 1500 = 375

sophomore(repeater) = 15% of 1500 = 225

students who graduated = 60% of 1500 = 900

Adding the total number of sophomores(freshmen who completed the year and sophomores that have to repeat the year)

sophomores = 1200 + 225 = 1425

Adding the total number of students who transfer,

500 + 500 + 375 = 1375

Adding the total number of student that graduated,

3000 + 900 = 3900

The transformation used to map AB to A'B' is not a rigid transformation since the measure of AB is greater than the measure of A'B' and not equal.

Transformation is the movement of a point from its initial location to a new location. Types of transformations are reflection, rotation, translation and dilation.

A rigid transformation is a transformation that preserves the shape and size such as rotation, reflection and translation.

Given the points A(-1, 13), B(1, 5), A'(2, 3), and B'(6, 1), hence:

[tex]AB=\sqrt{(5-13)^2+(1-(-1))^2} =\sqrt{68}\\\\A'B'=\sqrt{(1-3)^2+(6-2)^2}=\sqrt{20}[/tex]

The distance of AO and BO are the same so the given triangle will be an isosceles triangle.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

The given vertices are making a triangle as shown below in the figure.

Distance between A(5,12) and O(0,0) is

⇒ [tex]\sqrt{(5 - 0)^2 + (12 - 0)^2}[/tex]

⇒ 13

Distance between B(13,0) and O(0,0) is

⇒ [tex]\sqrt{(13 - 0)^2}[/tex]

⇒ 13

Since the two sides are the same so triangle will be isosceles.

Hence "The distance of AO and BO are the same so the given triangle will be an isosceles triangle".

Answer:

6²

Step-by-step explanation:

6² is 6×6 which is 36

if you write it as 6² then:

6²=6^x

since the bases are equal you can cancel out the bases and it becomes:

x=2

Answer:

a. 6^2

Step-by-step explanation:

A because six times itself is equal to 36.

Using Venn sets, it is found that:

For this problem, we consider the following sets:

2 are taking all subjects, hence:

(A ∩ B ∩ C) = 2.

8 are taking chemistry and math, hence:

(A ∩ C) + (A ∩ B ∩ C) = 8.

(A ∩ C) = 6.

6 are taking math and english, hence:

(A ∩ B) + (A ∩ B ∩ C) = 6.

(A ∩ B) = 4.

4 are taking chemistry and english, hence:

(B ∩ C) + (A ∩ B ∩ C) = 4.

(B ∩ C) = 2.

15 are taking chemistry, hence:

C + (A ∩ C) + (B ∩ C) + (A ∩ B ∩ C) = 15.

C + 6 + 2 + 2 = 15.

C = 5.

20 are taking english, hence:

B + (A ∩ B) + (B ∩ C) + (A ∩ B ∩ C) = 20

B + 4 + 2 + 2 = 20

B = 12.

18 are taking math, hence:

A + (A ∩ B) + (A ∩ C) + (A ∩ B ∩ C) = 18

A + 4 + 6 + 2 = 18

A = 6.

There is a total of 40 students, hence:

None + A + B + C + (A ∩ B) + (A ∩ C) + (B ∩ C) + (A ∩ B ∩ C) = 40.

None + 6 + 12 + 5 + 4 + 6 + 2 + 2 = 40.

None + 37 = 40.

None = 3.

The fraction for 0.1515... is 5/33

It is possible to convert non terminating decimals to fraction. Because decimals are originally obtained from fractions itself.

If we have a terminating decimal number, by multiplying and dividing with powers of 10 gives a fraction.

For example, for the decimal 0.25, multiply and divide it with 100 which gives, 25/100 = 1/4.

Now we need to find the fraction corresponding to the decimal 0.1515..

Let x = 0.1515...

First we take 100x = 15.1515...

Now we can subtract the decimal part completely from 15.1515... since it is non terminating.

Now, 100x - x = 15.1515..- 0.1515.. = 15

Therefore, 99x = 15

and x = 15/99 = 5/33

So 5/33 is the fraction for the decimal 0.1515...

The equation of the line in slope-intercept form with a slope of 1/2 and y-intercept of (0 , 0) is y = 1/2 x.

The equation of a line can be expressed in three different forms: standard form, slope-intercept form, and point-slope form.

The slope-intercept form of the equation of a line is given by the formula:

y = mx + b

where m is the slope of the line

b is the y- intercept

Given that the slope of the line is 1/2 and the y-intercept is (0 , 0), write the equation of the line by simply plugging in its values.

y = mx + b

y = (1/2)x + 0

Math: 54 minutes

Biology: 18 minutes

Step-by-step explanation:

Set up each subject with the variable x as the biology homework.:

English: (x+30)

Math: (3x)

Biology: (x)

Now add them together and set it equal to 120 (2 hours into minutes):

x + 30 + 3x + x = 120

Move 120 over to the left and simplify:

5x - 90 = 0

Solve:

5(x - 18) = 0

x - 18 = 0

x = 18

So biology is 18 minutes, and then plug 18 in for all the other subjects:

The correct answers would be options (A) and (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

We have been given two cases,

p: -3x + 8x - 5x = x

q: (3x)(5y) = 15xy

We have to need to isolate the variables:

p: -3x + 8x - 5x = x

⇒  (-3x - 5x) + 8x = x

⇒  -8x + 8x = x

⇒ x = 0

This is not always true, hence the statement is incorrect because this will hold true for only one value of x.

q: (3x)(5y) = 15xy

⇒ (3x)(5y) = 15xy

⇒ (3×5)(x×y) = 15xy

⇒ 15xy = 15xy

If both x and y are true for any value, then the statement is true.

Hence, p → q and q → p are false.

Therefore, the correct answers would be options (A) and (C).

The maximum and the minimum weight for the bags of sand are 36 and 35 pounds respectively

Here, we have

Weight = 35 pounds

Labeled weight = within 8 ounces

Convert ounce to pounds

So, we have:

Labeled weight = within 0.5 pound

The equation is then represented as

|x - 35| = 0.5

Where x represents the labeled weight

In (a), we have

|x - 35| = 0.5

Expand

x - 35 = 0.5 and x - 35 = -0.5

Add 35 to both sides

x = 36 and x = 35

Hence, the maximum and the minimum weight for the bags of sand are 36 and 35 pounds respectively

Answer:B. The number is composite. Its prime factors written as a product are (5*3^3*2^2)

Step-by-step explanation:

Since 540 is an even number, that means it can be divided by 2. This means that the number is composite.

You can keep dividing it by 2 until you can't anymore.

Once you divide 540 by 2 twice, then you get 135.

You can divide it by 5 because the ones digit is 5.

Then you get 27, which is 3 times itself 3 times.

You finally multiply the numbers you divided by, and you get 2*2*5*3*3*3, which is 5*3^3*2^2.
