The price of silver dropped a total of $14 in 3 and a half hours. What was the average change in price per hour?

Answer: $2.75

Step-by-step explanation:

2) Judy spent 3*5.25 = 15.75 on popcorn bags, 13.60 on a jumbo bag of chips and 7.90 for a dip. This means that overall she spent $37.25. If she had $40, this means that she have left $40 - $37.25 = $2.75.

1) Your answer is right.

Answer:

12

Step-by-step explanation:

(8+11+14+13+14+9+15)/7 = 12

Answer:

Total obs. = 7

Average = (n + 1 )/2

Average = 7 + 1 /2

= 8/2 = 4th obs.

= Sum of obs./ Total obs.

= 8,11,14,13,14,9,15/7

= 84/7

The unknown variables and angles are as follows:

The sum of angles on a straight line is 180 degrees.

Therefore, the sum of angles on line STA is 180 degrees.

CT bisect STE

Angle STE Is a right angle.

Therefore,

5x + y + 3 + 3x + 12 = 90

5x + 3x + y + 12 + 3 = 90

8x + y + 15 = 90

8x + y = 90 - 15

8x + y = 75

Ty bisect ETA

Angle ETA Is a right angle.

Therefore,

y + 41 + 5x + 4 = 90

5x + y + 45 = 90

5x + y = 90 - 45

5x + y = 45

Combine the equation

8x + y = 75

5x + y = 45

subtract equation(ii) from equation(i)

3x = 30

x = 30 / 3

x = 10

y = 75 - 80

y = -5

Therefore,

m∠YTE = y + 41 = -5 + 41 = 36°

Hhhhhhhhhhhhhhhhhh : x=-2

Answer:

(1) y = 8.45x

(2) Total cost: $42.25

Step-by-step explanation:

Let's see by constructing a first-hand example of the information we have.

$101.40 = 12x

Divide 12 on both sides.

When we divide 12 from both sides, we get the simplified answer of:

x = 8.45

This means that each pizza will be $8.45 each, therefore this will be out=r equation

y = 8.45x

(where x is the number of pizzas and y is the total amount cost.

To find the cost of 5large pepperoni pizzas, we use our equation above (y = 8.45x) and input a 5 in x;

y = 8.45(5)

y = 42.25

The total cost for the 5 pizzas will be $42.25.

The true statement  is that both √15 and √0.001 are irrational , the correct option is (c).

Rational Numbers can be defined as the  numbers that can be expressed in the form of p/q , where p and q are integers and q not equal to 0 .

For Example : 2/3 , 2, 8/3 are all Rational Numbers.

Irrational Numbers can be defined as the  numbers that cannot be expressed in the form of p/q where , p and q are integers and q not equal to 0 .

For Example : √2 , √37 are irrational as they cannot be expressed in the form of p/q.

In the question ,

two numbers √15 and √0.001 are given .

the first number √15 is not a perfect square , hence not an integer ,

-1000 represents Jenny's change in elevation.

Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers. The inverse additives of the corresponding positive numbers are the negative numbers. The boldface Z is a common mathematical symbol for the set of integers. A number that contains both positive and negative integers, including zero, is called an integer. There are no fractional or decimal parts in it. Integers include things like -5, 0, 1, 5, 8, 97, and 3,043.

2/12, 2/10, 2/8, 2/6, and 2/4.

Step-by-step explanation:

the order would be 2/17, 8/17, and 11/17 since the bottom number (denominator) stays the same while the numerator (top number) increases.

the order for the 2nd one would be:
7/21, 7/18, 7/14, 7/12, and 7/8. The reason for this is that when the numerator stays the same and the denominator increases, the value of the fraction decreases. For example, 1/2 is greater than 1/4, and 1/4 is more than 1/5 because 5 is greater than 4. This only works when the numerator (top number) stays the same.
The order for the 3rd one would be:
2/12, 2/10, 2/8, 2/6, and 2/4. Again, the numerator stays the same while the denominator changes. As the denominator goes down, the value of the fraction goes up.

The time taken to fill the bathtub by cold water is 14.4 minutes.

Given,

Time taken to fill a bathtub by both cold and hot water = 8 minutes

Time taken to fill the bathtub by hot water = 18 minutes

Time taken to fill the bathtub by cold water = t minutes

We have to find t.

We can take the full bath tub as 1.

Now,

We can equate the given data:

We get,

(8/18) + (8/t) = 1

Now, solve the equation:

((8 × t) + (8 × 18) ) ÷ (18 × t) = 1

(8t + 144) ÷ 18t = 1

8t + 144 = 18t

18t - 8t = 144

The continents that have a lower elevation than North America are Africa and Asia.

It should be noted that elevation simply had to do with the height above sea level of a particular thing. Any of numerous huge landmasses is referred to as a continent. Up to seven geographical regions are usually regarded as continents, based on convention rather than precise requirements.

A continent is one of the seven major land divisions on Earth. Asia, Africa, North America, South America, Antarctica, Europe, and Australia are the continents, in order of size.

In this case, the table shows negative integers to represent the lowest elevations below sea level on each of the 7 continents.

In the table, Africa has -512 and Asia had -1312. It should be noted that these are lower than in North America.

Answer:

f(-2) = 18

Step-by-step explanation:

In order to calculate a function of x, we replace x
For example
f(x) = x
f(-2) = -2

In this specific scenario

f(x) = 3 * (4 - x)
f(-2) = 3 * (4 - -2)

- -2 turns positive
f(-2) = 3 * (4 + 2)

Now we use PAMDAS (parentheses, exponents, multiplication, division, addition) as an operation order, so we first solve the parantheses
f(-2) = 3 * 6

f(-2) = 18
