Answer:

$50

Step-by-step explanation:

Solution:

Let the unknown number be x

50% × x = $25

50/100 × x = 25

x = 25×100/50

x = $50

Varification:

50% of $50 is $25

50/100 × 50 = 25

25 = 25

Answer:

Option 2. Acute and scalene.

Step-by-step explanation:

All the angles here are less than 90° and all the sides are of different length hence it is acute and scalene.

Hope this helps you. Good luck!

Please mark as brainliest. It helps a lot.

Answer:

Acute, Scalene

Step-by-step explanation:

Why do we know it's an Acute, Scalene triangle? All three sides and internal angles of that triangle are unequal, that is, all angles measure less than 90 degrees.

x. 34

4x = 34×10

x= 340/4

x= 85

the value of x is 85

Answer:

85 copies

Step-by-step explanation:

Number of copies for $4 = 10

Number of copies for $1 = 10 ÷ 4

Number of copies for $34 = [tex]\frac{10}{4}*34[/tex]

                  = 5*17

                   = 85 copies

Answer:

Step-by-step explanation:

We are required to find how many commercials the company can produce in year at a cost of $35,000

The company can produce 80 commercials in year at a cost of $35,000

Given:

C(x) = $225x + $17,000

If C(x) = $35,000

Then,

C(x) = $225x + $17,000

35,000 = 225x + 17,000

subtract 17,000 from both sides

35,000 - 17,000 = 225x

18000 = 225x

divide both sides by 225

x = 18,000 / 225

x = 80

Therefore, the company can produce 80 commercials in year at a cost of $35,000

Step-by-step explain

The machines represent equivalent expressions.

The output produced by both machines is 372

The equation represented on machine A is:

[tex]\mathbf{y = 2(5x + 3) - 24}[/tex]

The equation represented on machine B is:

[tex]\mathbf{y = 4(2(x + 11) - 7)}[/tex]

Where: x and y represent the inputs and the outputs, respectively

When the outputs are the same, it means:

[tex]\mathbf{y = y}[/tex]

So, we have:

[tex]\mathbf{2(5x + 3) - 24 = 4(2(x + 11) - 7)}[/tex]

Open brackets

[tex]\mathbf{10x + 6 - 24 = 8x + 88 - 28}[/tex]

[tex]\mathbf{10x - 18 = 8x + 60}[/tex]

Collect like terms

[tex]\mathbf{10x - 8x = 18 + 60}[/tex]

[tex]\mathbf{2x = 78 }[/tex]

Divide both sides by 2

[tex]\mathbf{x = 39 }[/tex]

Substitute 39 for x in [tex]\mathbf{y = 2(5x + 3) - 24}[/tex]

[tex]\mathbf{y = 2 \times (5 \times 39 + 3) - 24}[/tex]

[tex]\mathbf{y = 372}[/tex]

Hence, the output produced by both machines is 372

Step-by-step explanation:

Okay so, 22:40 is 10:40pm

07:32 is am

Time goes up to 60 minutes, it would be 52 minutes at the end(20m to get to 11pm + the 32minutes)

Then there would be 8 hours alone (11 to 7 is 8 hours)

So it takes 8 hours and 52 minutes from 10:40pm to 7:32am

Answer:

[0.45(many 0's)1] through [0.459] repeating 9

Step-by-step explanation:

All these numbers fall in between 0.45 and 0.46. So if you were to draw out a number line you can find all the answers in between, example being: 0.456, 0.45897, etc.

The decimal numbers are given as 0.451, 0.452, 0.453, and 0.454 respectively.

A decimal number is the representation of a number in whole and a part. The whole is represented by an integer while the part is equivalent to a number divided by the order of 10.

The given decimal numbers are 0.45 and 0.46.

In order to write the numbers between them, write the given decimals up to 3 places as follows,

The numbers are 0.450 and 0.460.

The four decimals between them are as follows,

0.451, 0.452, 0.453, and 0.454.

Hence, the four decimals that lies between 0.45 and 0.46 are given as 0.451, 0.452, 0.453, and 0.454 respectively.

Answer:

1) [tex]q = \frac{4p}{3} -\frac{5}{3}[/tex]

2) [tex]x = \frac{\sqrt{b -y + 2a} }{b}[/tex]

Step-by-step explanation:

1) 4(q + p) = 5 + 7q

  Multiply 4(q + p):

  4q + 4p = 5 + 7q

  4p - 5 = 7q - 4q

  4p - 5 = 3q

  [tex]\frac{4p}{3} - \frac{5}{3} = \frac{3q}{3}[/tex]

   [tex]\frac{4p}{3} - \frac{5}{3} = q[/tex]  or  [tex]q = \frac{4p}{3} - \frac{5}{3}[/tex]

Answer:

$500

Step-by-step explanation:

Simply change the 25% into a decimal which is 0.25 and multiply $2000.

Or you can change 25% into a a fraction which is 25/100 and simplify giving 1/4. Then simply multiply $2000 by the fraction: 2000/1×1/4. Cross multiply which is 2000×1/1×4=2000/4. Now simply divide 2000 by 4 and you get 500 as your answer.
