Step-by-step explanation:

Answer:

Well for example most video games cost $60, so if you divide the original price by 100 and multiply it by 30, you'll get 18, so you take away that from 60, then you'll get 42.

Step-by-step explanation:

60 divided by 100 = 0.6, times that by 30 = 18, take away that from the original price which was 60, you'll get 42.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

If the cost of the video game is $60

The cost of the video game after 30% off is $42

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

We will assume that the cost of the video game = $60

Percentage off = 30%

30% = 30/100

30% of 60 = 30/100 x 60 = 18

The cost after 30% off.

= $60 - 30% of $60

= 60 - 30/100 x 60

= 60 - 18

= $42

Thus,

If the cost of the video game is $60

The cost of the video game after 30% off is $42

Answer:

t = 8

Step-by-step explanation:

[tex]\frac{1}{4}t - 6 = -4\\ +6 \\^{*4} \frac{1}{4}t = 2^{*4} \\t = 8[/tex]

The value of t in the given expression is t = 8

Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.

Given is an expression we need to simplify it for t,

The expression is 1/4t - 6 = -4

So, add 6 to both sides,

1/4 t -6 + 6 = -4 + 6

1/4 t = 2

Multiply by 4 to each side,

1/4 x 4 t = 2 x 4

t = 8

Hence, the value of t in the expression given is 8

Answer:

which one do you need help on?

Step-by-step explanation:

The formula for percent error is:

((Approximate value -  exact value) / exact value) x 100

1) 14-12 = 2

2/12 = 0.1666

0.166 x 100 = 16.7%  (Rounded to nearest tenth)

2) 231 - 215 = 16

16/215 = 0.74419

0.74419 x 100 = 7.4419% ( Round as needed)

3) 17.1 - 16.5 = 0.6

0.6/16.5 = 0.36364

0.36364 x 100 = 3.6364% (Round off as needed)

4)  1081 - 1150 = -69

-69/1150 = -0.06

-0.06 x 100 = -6% = 6% error

Answer:

1) 85.7%

3) 96.5%

4) 94%

Step-by-step explanation:

So its difficult to show

Y= X-6 so what ever x is, y is six less than that so

X= -4 Y= -10

X= 0 Y=-4

X=4 Y=0

X=8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= 4/3x -2 so whatever x is y is 4/3 and 2 less then that

X=-4 Y= -5

X=0 Y= -2

X=4 Y=1

X= 8 Y= 4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Y= -2

Find minus 2 on the y axis and draw a horizontal line through it all the way across the grid.

Y= 2+ 1/4x  so whatever x is y is 1/4 of x add 2

X=-8 Y= 0

X= -4  Y = 1

X=0 Y=2

X=4 Y=3

X=8 Y=4

Then plot these on a graph like co-ordinates (x,y) and draw a straight line through them

Do this method for 9

y = 2x -3 so whatever x is, y is  2 times that -3

y=2x +1 so whatever x is y is 2 times that +1

y= 2x so whatever x is y is 2 times that

Then plot the answers on a graph like co-ordinates (x,y) and draw a straight line through them

Make sure to label each line

Answer: 1,796

Step-by-step explanation:

We are given that : At the chicken ranch this morning there were 7,149 chicks.

i.e. The number of new chicks before today = 7,149

Later  today some more chicks hatched. now the ranch has 8,945 chicks.

i.e. The number of new chicks after today = 8,945

Then, By Subtraction operation

Number of new chicks hatched today = ( Number of new chicks after today) - (Number of new chicks before today )

=  8,945- 7,149 = 1,796

Therefore , the number of new chicks hatched today =  1,796

Answer:Group of answer choices

Step-by-step explanation:

What you first want to do is like and unlike terms so basically liketerms are terms withthe same sign and unlike terms are terms with diferent signs for instinse 3g and 2g are like terms so -33 and -9 and -9 and 9 are unlike terms so you just have to find the like and unlike terms to answer the question!

Answer: -9

Step-by-step explanation: Let's solve your equation step-by-step.

3g+15−12+3−2g+4=1

Step 1: Simplify both sides of the equation.

3g+15−12+3−2g+4=1

3g+15+−12+3+−2g+4=1

(3g+−2g)+(15+−12+3+4)=1 (Combine Like Terms)

g+10=1

g+10=1

Step 2: Subtract 10 from both sides.

g+10−10=1−10

g=−9

So the answer is g=-9

Answer:

3/4

Step-by-step explanation:

The way to find slope is by using the slope formula (y1 - y2)/(x1-x2) where you have two points (x1, y1) and (x2, y2). Next, substitute these points into the equation and you would get (-3 - 1.5)/(-4-2), which is -4.5/-6. -4.5/-6 = 3/4, so the slope is 3/4.

P.S I TRIED MY BEST

Step-by-step explanation:

The required values of ratios are 9/16,3/2, 7/6 and 1/12 respectively. The only false option is (c).

A ratio is the relation between two numbers as a / b. A proportion is the equality of two ratios as a / b = c / d.

Ratio and proportion can be applied to solve Mathematical problems dealing with unit values of the quantities.

All the options are examined one by one as follows,

(a) The ratio of 5/8 to 10/9 is given as,

5/8 : 10/9

= (5/8) ÷ (10/9)

= 5/8 × 9/10

= 9/16

Thus, it is true.

(b) The ratio of  4/7 ∶ 8/21 is given as,

4/7 ∶ 8/21

= (4/7) ÷ (8/21)

= 4/7 × 21/8

= 3/2

Thus, it is true.

(c) The unit rate of 7/9 and 2/3 equivalent to the ratio given below,

7/9 : 2/3

= 7/9 ÷ 2/3

= 7/9 × 3/2

= 7/6

Thus, it is false.

(d) The unit rate of 9/16 and 27/4 equivalent to the ratio given below,

9/16 : 27/4

= 9/16 ÷ 27/4

= 9/16 × 4/27

= 1/12

Thus, it is true.

Hence, the ratios for the given options are obtained as 9/16,3/2, 7/6 and 1/12 respectively.
