Answer 1

Answer:

27/4 or 6 3/4

Step-by-step explanation:

Change all mixed numbers into improper fractions

2 1/9 = 19/9

6 1/4 = 25/4

19/9 ÷ 2/3 - 25/4 x 2/5

dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)

19/9 x 3/2 - 25/4 x 2/5

you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below

19/3 x 1/2 - 5/4 x 2/1

multiply across the fractions first PEMDAS, then subtract

19/6 - 10/4 (multiply by 2 and 3 respectively to get both bottom numbers the same, multiply by the same number on top)

57/12 - 30/12 = 27/12

1/5 x 1/3 + 2/5 x 2/3

1/15 + 4/15 = 5/15 or 1/3

27/12 / 1/3

you can multiply the fractions and flip the top and bottom numbers of 1/3

27/12 x 3/1

reduce 12 and 3

27/4 x 1/1 = 27/4 or 6 3/4

The triangular prism shown below is 6 \,\text{cm}6cm6, start text, c, m, end text wide and 4\,\text{cm}4cm4, start text, c, m, end text deep. The vertical height is 7\,\text{cm}7cm7, start text, c, m, end text. What is the length of the side edge, sss, of the triangular prism?

Answers

Answer:

The answer is "7.62 cm ".

Step-by-step explanation:

Given:

[tex]Width = 6\ cm \\\\Depth = 4 \ cm\\\\Vertical \ height = 7 \ cm\\\\[/tex]

Dividing the prism's face into two halves:

As just a result, the vertical height becomes 7cm, as well as the width, becomes [tex]\frac{6\ cm}{2} = 3 \ cm[/tex]. If the 's' on both sides of the edge is equal:

[tex]s^2 = width^2 + height^2\\\\[/tex]

   [tex]= \sqrt{(width^2 + height^2)}\\\\[/tex]  

   [tex]= \sqrt{(3^2 + 7^2)}\\\\= \sqrt{9 + 49}\\\\= \sqrt{58}\\\\= 7.62 \ cm[/tex]

Step-by-step explanation:

The function f is given by the table of values as shown below.

x 1 2 3 4 5
f(x) 13 19 37 91 253
Use the given table to complete the statements.

The parent function of the function represented in the table is_______.
If function f was translated down 4 units, the _______-values would be__________
A point in the table for the transformed function would be _____________

Answers

Answer:3^x

9, 15, 33, 87, 249

(4, 87) for example

Step-by-step explanation:

a) First differences of the f(x) values in the table are ...

 19 -13 = 6, 37 -19 = 18, 91 -37 = 54, 253 -91 = 162

The second differences are not constant:

 18 -6 = 12, 54 -18 = 36, 162 -54 = 108

But, we notice that both the first and second differences have a common ratio. This is characteristic of an exponential function. The common ratio is 18/6 = 3, so the parent function is 3^x.

__

b) Translating a function down 4 units subtracts 4 from each y-value. The values of f(x) in the table would be ...

 9, 15, 33, 87, 249

__

c) The x-values of the function stay the same for a vertical translation, so the points in the table of the transformed function are ...

 (x, f(x)) = (1, 9), (2, 15), (3, 33), (4, 87), (5, 249)

i hope this helps

The parent function of the function represented in the table is exponential.

What is a function?

A function simply defines a relationship between one variable and another variable which is the dependent variable.

If function f was translated down 4 units, the f(x) values would be increased by 5. Also, the point in the table for the transformed function would be (2, 16).

Linda needs 6/9 cup of strawberries and 3/4 cup mashed peach for a recipe. She wants to find whether she needs more peaches or strawberries. How can you write 6/9 and 3/4 as a pair of fractions with a common denominator?

Answers

Answer: Smashed Peach i.e.  [tex]\dfrac{27}{36}[/tex]

Step-by-step explanation:

Given

Linda needs [tex]\frac{6}{9}[/tex] cup of strawberries

and [tex]\frac{3}{4}[/tex] cup of mashed peach for a recipe

For two fractions to have the same denominator, take L.C.M. of the denominator

[tex]\Rightarrow \text{L.C.M.(4,9)}=36[/tex]

[tex]\therefore \dfrac{6}{9}=\dfrac{6\times 4}{36}=\dfrac{24}{36}\\\\\Rightarrow \dfrac{3}{4}=\dfrac{3\times 7}{36}=\dfrac{27}{36}[/tex]

Therefore, she needs more mashed peach for the recipe.

FSelect the correct answer. Consider these functions: f(x)=4x^3-10 g(x)=3x-4/2 What is the value of g(f(2))? A. -6 B. 2 C. 19 D. 31

Answers

Answer:

D. 31

Step-by-step explanation:

First we need to find what the value of f(2) is, so we are going to substitute x for 2 in f():

f(2)=4(2)^3-10

= 4(8)-10

= 32-10

= 22

And then we substitute 22 for x in g()

g(22)= (3(22)-4)/2

= (66 -4)/2

= 62/2

= 31

The ratio of the number of games won to the number of games lost (no ties) by the Middle School Middies is
11/4. To the nearest whole percent, what percent of its games did the team lose?

Answers

Answer:

27%

Step-by-step explanation:

The ratio means that for every 11 games won, 4 are lost, so the team has won 11x games, lost 4x games, and played 15x games for some positive integer x. The percentage of games lost is

4x / 15x * 100 = 4/15 * 100 = 26.6666 = 27%

A percentage is a way to describe a part of a whole. To the nearest whole percentage, the percentage of games lost by the team is 27%.

What are Percentages?

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given the ratio of the number of games won to the number of games lost is 11/4, therefore, the total number of games played by the team is 15(11+4).

Now, the percentage of games lost by the team is,

4/15 × 100% = 26.6667% ≈27%

Hence, To the nearest whole percentage, the percentage of games lost by the team is 27%.

what two numbers multiply to 20 and add up to 9

Answers

Answer:

4 and 5

Step-by-step explanation:

The solution of the numbers 4 and 5 that gives multiplied by 20 and adds up to 9.

Used the concept of the equation that states,

An equation is a group of numerical variables and functions that have been combined using operations like addition, subtraction, multiplication, and division.

Given that,

The multiplication of two numbers is 20.

And, the addition of both numbers is 9.

Let us assume that the numbers are x and y.

Hence the equation for the given conditions,

[tex]x \times y = 20[/tex]  ... (i)

[tex]x + y = 9[/tex]   ... (ii)

From (ii);

[tex]x = 9 - y[/tex]

Substitute in (i);

[tex](9 - y) \times y = 20[/tex]

[tex]9y - y^2 = 20[/tex]

[tex]y^2 - 9y + 20 = 0[/tex]

[tex]y^2 - (5 + 4)y + 20 = 0[/tex]

[tex]y^2 - 5y - 4y + 20 = 0[/tex]

[tex]y (y - 5) - 4 (y - 5) = 0[/tex]

[tex](y - 5) (y - 4) = 0\\[/tex]

This gives,

[tex]y = 5\\y = 4[/tex]

From (i);

Substitute y = 5;

[tex]x = 9 - 5\\x = 4[/tex]

Substitute y = 4;

[tex]x = 9 - 4\\x = 5[/tex]

Therefore, the numbers are 5 and 4.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

At schools art teacher designs a circular flower bed inside a rectangular sandbox.

Here, We have;

The sandbox is 6 feet wide and 10 feet long.

Now, We get;

Radius of circle = 5 feet

Hence, Area of circle = πr²

⇒ Area of circle = 3.14 × 5²

⇒ Area of circle = 78.5 cm²

And, Area of rectangular sandbox is,

⇒ 10 × 6

⇒ 60 feet²

Thus, There will be after the flower bed is installed = 78.5 - 60

                                                                               = 18.5 feet²
