If 1/5 of the money in a cash box is 30 dollars, how much money is in the cash box?

Answers

Answer:

Money in the cash box is $150

Step-by-step explanation:

Let

x = money in the cash box

1/5 of the money in a cash box is 30 dollars

1/5 of x = $30

1/5 * x = 30

1/5x = 30

Divide both sides by 1/5

x = 30 ÷ 1/5

= 30 × 5/1

= 150/1

x = $150

Money in the cash box is $150

You want to share a one kilogram gold bar with your friends. How many friends can you give one gram to, if you divide up the gold bar? You want to share a one kilogram gold bar with your friends. How many friends can you give one gram to, if you divide up the gold bar? 1. 1,000 2. 10 3.10,000 4. 100

Answers

Answer:

1,000 friends will get 1 gram of gold bar each from 1 kilogram of gold bar

Step-by-step explanation:

1 kilogram of gold bar = 1,000 grams of gold bar

You have 1 kilogram of gold bar

You want each of your friends to get 1 gram

Number of friends that will get 1 gram of gold bar each = 1 kilogram of gold bar / 1 gram

= 1000 gram / 1 gram

= 1,000

Number of friends that will get 1 gram of gold bar each = 1,000 friends

-5(4x-2) = -2(3+6x)
what is the answer and how do you get it

Answers

Answer:

x = 2

Step-by-step explanation:

-5(4x - 2) = -2(3 + 6x)

-20x + 10 = -6 - 12x            Distribute -5 to 4x and -2 and distribute -2 to 3 and

                                           6x

10 = -6 + 8x                        Add 20x to both sides

16 = 8x                                Add 6 to both sides

2 = x                                   Divide 8 to both sides

Answer:

-0.5

Step-by-step explanation:

-5(4x-2) = -2(3+6x)

-20x-10 = -6-12x

-10 = -6+8x

-4 = 8x

-0.5 = x

What is a quadratic equaton?

A quadratic equation is an algebraic expression in the form of variables and constants.

A quadratic equation has two roots as it's degree is two.

We know the graph of a quadratic equation ax² + bx + c is a parabola that opens upwards and is symmetrical about the y-axis.

Given, a parabola f(x) = 2x² - 5x + 3.

Now it is changed to f(x) = 2x² - 5x + 1 which also can be written as,

f(x) = 2x² - 5x + 3 - 2, So it has been translated 2 units down along the y-axis.

In an algebraic expression what is the product of 15 and c

Answers

Answer:

15c

Step-by-step explanation:

15 multiplyed by c gives 15c

In an algebraic expression, the product of 15 and c can be represented as 15c.

The term "product" refers to the result of multiplying two or more numbers or variables together. In this case, we are multiplying the number 15 by the variable c.

The expression 15c represents 15 multiplied by the value of c. It can be thought of as 15 times an unknown value represented by c. The variable c can represent any real number or algebraic expression, depending on the context of the problem or equation.

For example, if c is equal to 2, then the product 15c would be equal to 15 multiplied by 2, resulting in 30. Similarly, if c is equal to -3, then the product would be -45 since multiplying 15 by -3 gives -45.

Two consecutive even integers add up to 1594. what are the two numbers?

Answers

Answer:

Hey there!

Consecutive integers mean that the numbers are next to each other.

Consecutive even integers mean that the numbers are separated by a number between them.

Thus, if x is the smaller number, x+2 can be used to write the larger number.

x+x+2=1594

2x+2=1594

2x=1592

x=796.

The two numbers are  796 and 798.

Walter is planning a hiking trip and he estimated the gradient of trail to be 213.6 ft/mile. After hiking and tracking the trail, he found that the trail was actually 202.7 ft/mile. What was his percent error? Did he overestimate or underestimate the gradient?

Answers

Answer: His percent error = 5.38 %

He overestimated the gradient.

Step-by-step explanation:

Formula : [tex]Percent\ error =\dfrac{|Estimated\ value- Actual\ value|}{Actual\ value}\times100[/tex]

Given, Estimated gradient of trail  = 213.6 ft/mile

Actual gradient of trail  =  202.7 ft/mile

Since,  213.6 > 202.7 , that means he overestimated the gradient.

Percent error: [tex]\dfrac{|213.6-202.7|}{202.7}\times100[/tex]

[tex]=\dfrac{10.9}{202.7}\times100\\\\\approx5.38\%[/tex]

Hence, percent error = 5.38 %

A scale drawing of a school bus has a scale of 1 inch to 5 feet. If the length of the school bus is 6 inches on the scale drawing, what is the actual length of the bus? Explain or show your reasoning. *

Answers

Answer: 30 Feet

Step-by-step explanation:

In Technical drawings scales are used to reduce the size ( scaling ) of drawings so they fit in our drawing sheets. in this example above the drawer stated that 1inch was representing 5feet. what this means is that because we can’t get a drawing sheet which would be 40-100 feet wide we need to rescale our drawing to fit into the available sheet. So by saying 1inch equals 5feet this means the school bus is 30Feet in length.
