Answer 2

Answer:

(7.5,4.1)

Step-by-step explanation:

Given

3x_7y =_40

3x_2y=_4

sol

3x_7y=_40..... equation 1

3x_2y=_4 ..... eq 2

here

eq 2 multi 3 eq 1 multiply 3

9x_21y=_120

9x_6y=_12

_ + = +

__________

0x+ 15y =108

y=108÷15

what is 0.000036÷180 in standard form

Answers

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] .

How do you express a number in standard form?

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] .

Joe and John have Repair shops. Joe charges $11.25 per hour for repairs. The table below show's John's rate: Who earns more money per hour? How much more money does that person charge per hour?

Answers

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! :)

Need help with the correct answer please! Thank you. Which two triangles are congruent by the SSS Theorem? I picked D but that is the wrong answer.

Answers

Answer:

B

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

Which of the following represents “three times the abscissa decreased by the ordinate is twenty-two”?

3 x = 22 - y
y - 3 x = 22
3 x - y = 22

Answers

Answer:

3x - y = 22

Step-by-step explanation:

The abcisssa is known as the x coordinate while the ordinate is the y coordinate

abcissa = x

ordinate = y

“three times the abscissa = 3x

“three times the abscissa decreased by ordinate is expressed as;

3x - y

Is the result is 22, hence;

3x - y = 22

this gives the required expression

HELP WHAT IS THE AREA OF THE COMPOSITE FIGURE

Answers

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]

1. A TV is on sale for $399, or 16% off. What was the original price of the TV? Show your work.
2. A computer is on sale for $450.50, or 15% off. What was the original price of the computer? Show your work.

Answers

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
