Of the 300 television sets sold at an electronics store last month, 90 were flat screen TV's. What is the ratio of flat-screen TV's to other TV's sold last month?

I don't know how to do this. I would appreciate some help. thanks!!​

Answers

Answer 1

Answer:

300 television sets total

300 - 90 flat screens = 210

flat screens 90:210 other TVs

now divide each side of the ratio by a common factor to simplify. I'm going to use 30

flat screens 3:7 other TVs

this cannot be simplified any further so the ratio is

flat screens 3:7 other tvs

The diameter of a circle is 9 cm. Find its area to the nearest tenth.

Answers

63.6 cm

Cut diameter in half to find radius

9/2 = 4.5

radius = 4.5

This is the formula for area of a circle:

pi * radius^2

pi * 4.5^2

20.25pi

Now find pi:

20.25 * pi = 63.6

Answer:

63.6 cm is the area

Answer:

63.6

Step-by-step explanation:

1. A = πr²

2. Find the radius (r). Since the radius of a circle is the diameter/2, the radius is 9/2, which is 4.5

3. Now that we know the radius, we plug it into our formula: A = π(4.5)²

4. Simplify: A = 3.14(20.25)

5. A = 63.62

6. Rounding to the nearest tenth makes your answer 63.6

Which of the following is the product (5y − 3)2?

Answers

Answer:

= 10y − 6 is your answer

Step-by-step explanation:

option B is correct, 25y²-30y+9 is the product of (5y − 3)².

What is Expression?

The combination of numbers, variables, and operators is known as Expression.

The given expression is (5y − 3)²

The process of determining the product of two or more numbers is Multiplication.

The expression is five times of y minus three to the power of two.

From algebraic identity we have (a-b)²=a²+b²-2ab

Now (5y − 3)²

(5y)²+3²-2(5y)(3)

25y²+9-30y

Twenty five y to the power of two plus nine minus thirty times of y.

25y²-30y+9 is the expression after product of  (5y − 3)².

Hence, option B is correct, 25y²-30y+9 is the product of (5y − 3)².

Lebron James's Free Throw % is 75%

What is the probability that he makes 6 Free Throws in a row?

Answer as a decimal rounded to 2 places.

Answers

Answer: 0.18

Step-by-step explanation:

From the question, we are informed that Lebron James's Free Throw % is 75%. The probability that he makes 6 Free Throws in a row would be gotten by multiplying 75% six times. This will be:

= 75% × 75% × 75% × 75% × 75% × 75%

= 3/4 × 3/4 × 3/4 × 3/4 × 3/4 × 3/4

= 729/4096

Write an exponential function to model the following situation.
A population of 130,000 grows 3% per year for 16 years.
How much will the popluation be after 16 years?
Write an exponential function in terms of x.
y=10

Answers

Answer:

y = 130,000(1.03)ˣ

Step-by-step explanation:

The general form of an exponetial function is y = abˣ, where a is the initial value (when x = 0), and b is the multiplier (the growth or decay factor). Here, we start with a population of 130,000, so our initial value a = 130,000. A growth of 3% each year represents a growth factor of 1.03, so after x years, the population y should be y = 130,000(1.03)ˣ.

The exponential function in terms of x and y is y = 130,000(1.03)ˣ

What is an exponential function ?

The exponential function is a mathematical function denoted by

y = abˣ

where a is the initial value (when x = 0)

and b is the multiplier (the growth or decay factor).

population starts from 130,000, so

Initial value a = 130,000.

A growth of 3% each year represents a growth factor of 1.03,

so after x years, the population y should be

y = 130,000(1.03)ˣ

Therefore , The exponential function in terms of x and y is y = 130,000(1.03)ˣ

Step-by-step explanation:

(4z +9) + ( 9y - 2) =180

4z + 9y = 173 ....... Equation 1

The angles of triangle = 180

We miss one angle and in opposite of that angle is 135 so

( 5y +5 +4z +9)+135 = 180

5y + 4z + 149 = 180

5y + 4z = 31 ....... Equation 2

Subtract between two equations 1 & 2

= 1.23%

Answer:

1.23

Step-by-step explanation:

Hey there !!!!!

4.1% of 30

if we solve it :

Y is 4.1% of 30

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 4.1% * 30

Converting percent to decimal:

p = 4.1%/100 = 0.041

Y = 0.041 * 30

Y = 1.23

therefore:

4.1% of 30 = 1.23

Science Mysteries: How Many Species Are There? You might think that after 200 years, the scientists who find, name, and describe Earth's species would be close to finished. But taxonomists, as organized as they may be, have no idea how many species Earth has. Nor can they even provide an educated guess. Although reporting over 16,000 new species every year, taxonomists still cannot predict how many more are undiscovered. In total, taxonomists have categorized and listed 1.2 million species on Earth. At this point, you would think scientists should be able to use the information they have gathered to make good predictions about how many species an ecosystem can support. This would help them make better predictions about how many species are left to identify. So far, however, the guesses seem to vary so greatly that it seems there is no good theory for making a prediction. One of the main problems is that most of the places that seem to have a lot of diverse species are in places that are hard to get to. One such place is the ocean, where scientists believe some 80 percent of Earth's creatures are hiding at depths too deep for us to study. In addition, many of the planet's most diverse areas are in remote places with few taxonomists. Despite all the unknowns, scientists have agreed that there are between five and 15 million species left to discover on Earth. This is a huge range, but whether it's five or 15, taxonomists clearly still have a lot of work to do. And who knows, there may yet be a dragon or a Loch Ness monster left to discover. Which line from the text explains the main idea of the entire essay? (1 point) A. Scientists have agreed that there are between five and 15 million species left to discover.B.
