Rebecca had these results when she drew 10 tiles from the bag. The bag has a total of 20 tiles. Her classmates got similar results. What is a good predication for the number of green and red tiles out of 20?

Answers

Answer 1

Answer:

10/20

Step-by-step explanation:

if she has 20 in total and there's only two colours I would assume it's an even chance,

For example a coin has two sides, = even chance of getting each side.

Good luck hope this helped

Step-by-step explanation:

The smiley face has a radius of 8 centimeters.

We need to find the area of the smiley face.

The formula to find the area of a circle is:

A = [tex]\pi[/tex]r²

A = (3.14)(8)(2)

A = (25.12)(2)

Q: Which statement is correct for the graph of the specified function?

A: The maximum value of the quadratic function occurs at y = 4.

Step-by-step explanation: The minimum value of the quadratic function occurs at x = 0 is false because this quadratic does not have a minimum value. It has a maximum value when y=4. The true statement is that the x-values of the linear function increase (go up) as the y-values decrease (go down). Also i took the test

• If the developers paid $500.00 per square block, how much did they pay for all the property being developed? Explain your answer.

Answers

Answer:

$97500.00

Step-by-step explanation:

the homes of the homes facing south is 10 times (7 plus 3) = 100 blocks

the area of the east facing homes is 8 times 10= 80 blocks

and the area of the trapezoid is 5 plus 3 times 3 = 15 blocks

so 100+80+15= 195 square blocks

195 times 500 = $97500.00

Tyrone read a book for his school project. On the first day, he read 40 pages. On the second day, he read 1 4 of the remaining pages. After the second day, he still had to read 1 2 of the total number of pages to complete the book. How many pages are there in the book?

Answers

Answer:

160

Step-by-step explanation:

he read 40 pages on the first day. he read 1/4 of the remaining pages, and still had 1/2 of the book to read. this means that 40 is about 1/4 and to find the total amount of pages, you have to multiply 40 by 4.

40 x 4 = 160

hope this helps :)

Answer:

70 pages. (If by 1 4 and 1 2, you mean fractions.)

Step-by-step explanation:

1/4 of 40 is 10. This is calculated by dividing 40 by 4, since the denominator in 1/4 is 4.

1/2 of 40 is 20. This is calculated by dividing 40 by 2, since the denominator in 1/2 is 2.

Add that together and that's 70.

Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?

Answers

Answer:

there are so many ways

Step-by-step explanation:

such as observing day by day and checking its height with a scale everyday etc

The number of ways of combining different growth factors to form a level is 80.

What is Permutation?

The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.

A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.

nPr = (n!) / (n-r)!

What is a Combination?

The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).

A combination is a selection of r items from a collection of n items with no replacements and no regard for order.

nCr = (n!)/{(r!)((n-r)!)}

How do we solve the given question?

We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.

Growth factor Levels

Lighting: Low, Medium, High, Very high.

Age: 1 month, 2 months, 3 months, 4 months, 5 months.

Temperature: 20°, 22°, 24°, 26°.

We are asked to find the number of ways in which she can combine different levels to form one level.

We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.

Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).

Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).

Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).

∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80

∴ The number of ways of combining different growth factors to form a level is 80.

Answers

Answer:

x=1

Step-by-step

Step 1:

Simplify x/x2

Dividing exponential expressions :  

1.1    x1 divided by x2 = x(1 - 2) = x(-1) = 1/x1 = 1/

Equation at the end of step 1:

  2    1         1

 (((—+1)-—)-1)-((2•—)-1)  = 0

    x    x         x

STEP 2:Rewriting the whole as an Equivalent Fraction:

2.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  x  as the denominator :

        1     1 • x

   1 =  —  =  —————

        1       x  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

——— = ———

STEP 3:

Simplify 1/x

Equation at the end of step 3:

2          1           (2 - x)

 (((— +  1) -  —) -  1) -  ———————  = 0

    x          x              x  

STEP4:

Simplify: 2/x

Equation at the end of step 4:

    2          1                 (2 - x)

 (((— +  1) -  —) -  1) -  ———————  = 0

    x          x                      x  

STEP 5:

Rewriting the whole as an Equivalent Fraction :

5.1   Adding a whole to a fraction

Rewrite the whole as a fraction using  x  as the denominator :

        1         1 • x

   1 =  —  =  —————

Equation at the end of step 5:

STEP 6:Adding fractions which have a common denominator :

Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(x+2) - (1)                            x + 1

 — -  ———————  = 0

 x         x

STEP 8:

Adding fractions which have a common denominator :

8.1       Adding fractions which have a common denominator

When a fraction equals zero :

9.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 x-1

 ——— • x = 0 • x

  x

Now, on the left hand side, the  x  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  x-1  = 0

.2      Solve  :    x-1 = 0

Add  1  to both sides of the equation :

                     x = 1

One solution was found :

B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis

Answers

Answer:

B

Step-by-step explanation:

This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is  (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

Answer:

Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x +1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected.

The answer:

Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells

how do we know:

because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.

because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.

because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5
