Answer:

The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. Six groups have accepted names as well as assigned numbers: for example, group 17 elements are the halogens; and group 18 are the noble gases. Also displayed are four simple rectangular areas or blocks associated with the filling of different atomic orbitals. #2-118

Identify and label the point on the double number line that represents the original amount of money in Mr. Peralta's savings account.

Answers

Answer:

ima say $360.correct me if im wrong-^-

Step-by-step explanation:

The total amount of money in Mr. Peralta's savings account is $360.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, Mr. Peralta had $300 in his savings account in March.

By August, the value of the savings account had increased by 20%.

Let, 'x' be the total amount after an increase of 20%.

So, 120% of $300 is 'x'.

Therefore,

(120/100)×300 = x.

300×1.2 = x.

x = 360.

So, By august total money in his account is $360.

Answers

Answer:

4. 23

4. 206

5. 75 ft

7. 6 sections

8. 6 families

Step-by-step explanation:

4. 3x + 5 is the same thing as 3 x 6 + 5 so it equals to 23

4. x to the power of 3 - 10 is equal to 6 to the power of 3 - 10 so it equals to 206

5. Formula for area of triangle = 1/2 x base x height

So, it's 1/2 x 10 x 15 = 75

7. 3/4 ÷ 1/8 = 6 (Trick: When dividing fractions, make sure to flip the fraction for the 2nd one and leave the 1st one as the same. After that, multiply them together)

8. 3 families have 4-5 pets, 2 families have 6-7 pets and 1 family have 8-9 pets. At least 4 pets means 4 pets and above. So 3 + 2 + 1 = 6 families.

4.      3x + 5. Substitute the X for 6. The expression is (3 x 6) + 5= 23.

X³ - 10. Substitute the X for 6. 6³-10= 216.

5.       I'm not 100% sure but I believe that it is 75. I might be wrong.

6.       6

7.       6
