9.) A= 23mm².

P= 20mm.

T= PARALLELOGRAM.

Step-by-step explanation:

9.) A=(5+5) × 1/2 × 4.6

= (10) × 1/2 × 4.6

= 5mm× 4.6 mm

In a mathematics​ class 54, students received an A on the third​ test, which is ​150% of the students who received an A on the second test. How many students received an A on the second​ test?

10,1 #16

Answers

Answer:

Number of students who received A grade on the second test = 36

Step-by-step explanation:

Given that:

Number of students who received A grade on third test = 54

This is 150% of the students who received A on the second test.

Let,

x be the number of students who received A on the second test.

150% of x = 54

[tex]\frac{150}{100}x=54[/tex]

1.5x=54

Dividing both sides by 1.5

[tex]\frac{1.5x}{1.5}=\frac{54}{1.5}\\x=36[/tex]

Hence,

Number of students who received A grade on the second test = 36

What are some rules of exponents?

Some common rules of exponents are

xᵃ×xᵇ = xᵃ⁺ᵇ.

xᵃ/xᵇ = xᵃ⁻ᵇ.

Addition and subtraction of exponents is only possible for same base value and when the base is different and both have the same exponent we just multiply the bases and write the exponent.

The expression that equals to 10⁵ are,

10³.10².

Connor is working two summer jobs, making $8 per hour walking dogs and making $12 per hour landscaping. In a given week, he can work a maximum of 15 total hours and must earn no less than $160. If Connor worked 12 hours walking dogs, determine the maximum number of whole hours landscaping that he can work and still meet his requirements. If there are no possible solutions, submit an empty answer.

Answers

Answer:

[tex]\mathrm{No\: solutions}[/tex]

Step-by-step explanation:

Since Connor has worked 12 hours walking dogs, he's earned [tex]12\cdot 8 = \$96[/tex] from walking dogs. He still needs to earn [tex]\$160-\$96=\$64[/tex]. As stated in the problem, he makes $12 an hour landscaping, therefore the minimum number of whole hours he must work to fulfill his requirements is [tex]\lceil{ \frac{64}{12} \rceil = 6\: \mathrm{hours}[/tex]. However, the problem states he can only work a maximum of 15 hours. He would have to work [tex]12+6=18[/tex] to fulfill his requirements and therefore he will not be able to meet his requirements with the restrictions given.

Find the smallest non-zero whole number n such that 756n is a perfect cube.

Answers

Step-by-step explanation:

756 = 2² * 3³ * 7.

For 756n to be a perfect cube, all of its prime factors must have a power that is a multiple of 3.

How to get from 2² to 2³: Multiply by 2.

3³ has already a power that is a multiple of 3.

How to get from 7 to 7³: Multiply by 7².

Hence n = 2 * 7² = 98.

plz help

Answers

Answer:

Explained below

Step-by-step explanation:

A rational number is one that can be expressed in form a of a fraction whereby both the numerator and the denominator are integers.

Also, if it results in a recurring decimal it is still a rational number but if the decimal is not recurring, then it is not a rational number.

Now, for example let's consider the number 5.

It is a rational number because it can be expressed as; 5/1; 10/2; 20/4; -5/-1 e.t.c

Now, the opposite of these fractions like we are told to check in the question results in;

1/5; 2/10; 4/20; -1/-5;

The opposite will give us still a rational number because both numerator and denominator are still integers and also the value of the division is 0.2 which is a definite decimal and also can be expressed as an integer.
