Answer:

x = 12

WN = 28

Step-by-step explanation:

SO = WN and SO = 2WI

3x - 8 = 2(x + 2)

3x - 8 = 2x + 4

3x - 2x = 4 + 8

x = 12 now replace x with 12 in the first equation given

3x - 8 = 3×12 - 8

36 - 8 = 28

Answer:

15

Step-by-step explanation:

To find the common denominators for 2/3 and 1/5, just look at the denominators for both of the fractions, 3 and 5

Multiply 3 and 5, which is 15. 15 is the common denominator.

Answer:

Step-by-step explanation:

1) $399 = 84% of the original amount

Divide both sides by 84 to get what one percent would be

$4.75 = 1%

Then multiply both sides to get one hundred percent [the original price]

$475 =100%

Use this method to do the second question

$450.50 = 85%

Divide by 85

$5.30 = 1%

Multiply by 100

$530 = original price

Answer: 36/1000000 is the pq form of the given no..

Step-by-step explanation:

The standard form of 0.000036÷180 is  2 × [tex]10^{-7}[/tex] .

Any number that we can write as a decimal number, between 1.0 and 10.0, multiplied by a power of 10, is said to be in standard form. 1.23 × [tex]10^{8}[/tex]; If you observe carefully, 1.23 is a decimal number between 1.0 and 10.0 and so we have the standard form of 123,000,000 as 1.23 × [tex]10^{8}[/tex].

According to the question

0.000036÷180 in standard form

Now,

0.000036÷180

= [tex]\frac{0.000036}{180}[/tex]

= 0.0000002

= [tex]\frac{2}{10000000}[/tex]

= 2 × [tex]10^{-7}[/tex] is the standard form .

Hence, the standard form of 0.000036÷180 is  2 × [tex]10^{-7}[/tex] .

Answer:

a) 30 sixth-graders

b) 12 sixth-graders

Step-by-step explanation:

You can solve this problem by multiplying fractions. In order to solve a, you need to multiply 3/7 by 70 students to e t the number of sixth-graders because 3/7 of the population (in this case it's 70) are 6th graders:

70 × 3 ÷ 7 = 70 ÷ 7 × 3 = 30

So if the school has 70 students, 30 are 6th graders.

For part b, you multiply the student population (28) by the ratio 3/7 to find how many 6th grader there are:

28 × 3 ÷ 7 = 28 ÷ 7 × 3 = 12

So if the school has 28 students, 12 are 6th graders.

a) There are 30 sixth graders are there if the school has 70 students.

b) There are 12 sixth graders are there if the school has 28 students.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

3/7 of the students in a school are in sixth grade.

Now,

a) Let the students in school = 70

Then, Number of students in sixth grade = 3/7 × 70

                                                               = 3 × 10

                                                               = 30

b) And, Let the students in school = 28

Then, Number of students in sixth grade = 3/7 × 28

                                                               = 3 × 4

                                                               = 12

Thus, a) There are 30 sixth graders are there if the school has 70 students.

b) There are 12 sixth graders are there if the school has 28 students.

Answer:

7, 11, 13, 17, 19

All of these numbers only have 1 and themselves as factors, and every other number can be written as a product of two or more primes, making the remaining number composite:

Answer:

6 days

Step-by-step explanation:

Answer:

18 hours during the week days

Step-by-step explanation:

weekend pay + week day pay = total pay

93 + week day pay = 232.50

Subtract 93 from each side

93-93 + week day pay = 232.50-93

week day pay = 139.50

She makes 7.75 per hour

139.50 = hours * pay rate

139.50 =  hours*7.75  

Divide each side by 7.75

139.50/7.75 = hours

18 = hours

Answer: John earns $0.25 more an hour than Joe does.

Step-by-step explanation: 3 hours is equivalent to $34.50 in payouts, meaning in order to get the hourly charge you would have to divide 34.50 by 3. Which is 11.5 or 11.50. 11.25 is 0.25 below 11.50. Hope this helps! :)

Answer:

[tex]76 ft^3[/tex]

Step-by-step explanation:

First, split the figure into two different rectangular prisms. I found it easiest to split it like this (image attached below).

To find the volume of the lower prism, multiply the Length (6ft) x Width (2ft) x Height (3ft).

6 * 2 * 3 = 36 [tex]ft^3[/tex]

Next, subtract 3 from 8 to get the height of the top prism. 8 - 3 = 5, so the height of the top prism is 5.

Multiply the Length (4ft) x Width (2ft) x Height (5ft).

4 * 2 * 5 = 40 ft[tex]^3[/tex]

Add the two volumes.

40 + 36 = 76 ft^3.

Final answer: [tex]76 ft^3[/tex]

Step-by-step explanation:

RQ=TV

QS=VU

RS=TU

While proving that 2 triangles are congruent you have to consider the same side for both triangles.

The mistake you made was that you presumed that since both have equal sides they are equal,

In a sense that is true but you have align it in the correct way, in option D) it shows RQ is equal to TU which is wrong, RQ is equal to VT, you have align it in a proper way.

B) ΔRQS ≅ ΔTVU here it is align perfectly to be matched

Step-by-step explanation:

Given

The area of the square is [tex]A=16x^4y^8[/tex]

Suppose a is the side length of the square

The area of the square is given by

[tex]\Rightarrow A=(\text{side length})^2[/tex]

So, we can write

[tex]\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4[/tex]

length of each side is [tex]4x^2y^4[/tex]
