How many times smaller is a group of 19 coins than a group of 76 coins?

Answers

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

Ok I like looking at these type of questions like this. If you have 76 students and you want to put them in groups of 19. How many groups would you have?

That's easier for my brain to comprehend and now I know that all I have to do is divide the 76 students by 19 to get 4 groups.

So in your problem the 19 coins would be 4x smaller than the 76 coins.

The polynomial has  3  real zeros and  2  complex zeros.

What is polynomial function ?A quadratic, cubic, quartic, and other functions involving only non-negative integer powers of x are examples of polynomial functions. We can define a polynomial's degree and provide a generic definition for it.Zero polynomial function, linear polynomial function, quadratic polynomial function, and cubic polynomial function are the four most prevalent types of polynomials used in precalculus and algebra.A polynomial function whose all coefficients of the variables and constant terms are zero. In other words, zero polynomial function maps every real number to zero, f: R → {0} defined by f(x) = 0 ∀ x ∈ R.

   Both terms , the values of a polynomial f(x) that make f(x)= 0.

  a polynomial whose coefficients are real numbers, but the field of real numbers is not algebraically closed.

The polynomial may very well have roots that are complex numbers, not real .

Let [tex]x^{2}[/tex] + 1 = 0 has root i and -i .

In this polynomial function we got 3  real zeros and  2  complex zeros.

what's the total area of each smaller space is 5 feet on each side

Answers

Answer:

100

Step-by-step explanation:

100

The total area of the four squares is the sum of each individual area of each square. Hence, the total area of the square is 100 ft²

Given that :

Side length of each square, s = 5 feets Area of a square =

The area of each square can be calculated thus :

Area = = 25 ft²

The area of the entire square :

(5² + 5² + 5² + 5²)

(25 + 25 + 25 + 25) = 100 ft²

The total area of the square is 100 ft²

the perimeter of an equilateral triangle is 8 inches more than the perimeter of a square, and the side of the triangle is 5 inches longer than the side of the square. Find the side of the triangle

Answers

Answer:

An equilateral triangle has all 3 sides the same length

If one side of the triangle has length x, the perimeter = 3x

 

If one side of the square is 5 less than a side of the triangle

then the square has side length x-5 and perimeter 4(x-5) = 4x-20

 

Since the perimeter of the triangle is 7 more than

the perimeter of the square then our equation is:

 

3x = 4x-20+7

3x = 4x-13

x = 13

 

The sides of the triangle are 13 inches

The sides of the square are 13-5=8 inches

Sam traveled 7.5 kilometers from his house to reach the highway. On the highway, he travels at an average speed of 55 kilometers per hour. Which equation can be solved to find t, the time in hours Sam travels on the highway to reach a farm 22 kilometers away from his house?

Answers

Answer:

0.2636 hrs

Step-by-step explanation:

Number of kilometers from Sam's house to highway = 7.5 km

Average speed traveled on highway = 55km/hr

Which equation can be solved to find t, the time in hours Sam travels on the highway to reach a farm 22 kilometers away from his house?

Time traveled (t) to reach a farm 22 kilometers from his house :

t = time in hours Sam travels on the high way:

Distance from highway to farm = (Distance of farm from Sam's house - distance from Sam's house to highway)

22km - 7.5km = 14.5km

Speed of travel on highway = 55kmph

Travel time = distance / speed

Travel time = 14.5km / 55km/hr

Travel time = 0.2636 hrs

1. Miss Firkin is selling her Nike Air Force Ones. She bought them online for $75.00, but they were too big for her and she's tripping all over herself (scuffing the tips). She needs to make some extra money to buy Halloween candy....She wants to mark up the sneakers 150%. What is she charging for them?

2. Miss Firkin went to Wal-Mart and iced cupcakes that were $12.99 a box had a sticker that said 30% off. How much is one box?
What did she pay for 3 boxes?

3. Now, what if the cupcakes are taxed as fast food items at a rate of 9%?

4. How much does she now spend on the 3 boxes?

5. Gas was $1.25 per gallon. Now it is $1.38 per gallon. What percent did it increase by? (really not that tricky)

Answers

1. I beleive it would be 187,5$, 75.00 + 150% = 187,5.

2. if rounding it would be 9.1$ she had to pay for one times 3 would be 27.3 for three boxes.

3. Not sure what this question is asking but I'll try my best so here: 27.3 +9% × 3 = 89.271 rounded would be 90$

4. 90$ if I did that correctly

5. 1.38 - 1.25 = 0.13 which I beleive would be 13%

0.13 as a percent woudl be 13%

A fish tank measures 10 inches long and 5 inches wide. Micheal wants to buy a fish tank that can hold 150 cubic inches of water. What is the independent and dependent variable

Answers

Answer:

h = 3 inches

Step-by-step explanation:

Volume of the fish tank = length × width × height

Volume = 150 cubic inches

Length = 10 inches

Width = 5 inches

Height = x

Volume of the fish tank = length × width × height

height = volume of the fish tank / length*width

h= 150 / 10*5

h = 150 / 50

= 3

h = 3 inches

The height = 3 inches

From the height formula,

height = volume of the fish tank / length*width

The dependent variable is height

The independent variable are length, width and volume
