Answers

Answer 1

Answer:

1.  16 ft

[tex]\sf 2.\quad \dfrac{29}{99}[/tex]

Step-by-step explanation:

Question 1

Formula

Area of a square = s²  (where s is the side length)

Given:

Area = 256 ft²

Substitute the given area into the formula and solve for s:

[tex]\sf \implies 256=s^2[/tex]

[tex]\sf \implies \sqrt{256}=\sqrt{s^2}[/tex]

[tex]\sf \implies s=\pm 16[/tex]

As distance is positive, the length of one side of Keisha's kitchen is 16 ft.

Question 2

Converting a recurring decimal to a fraction

Let x equal the recurring decimal:

[tex]\implies \sf x=0.292929...[/tex]

Create another number with recurring 29s by multiplying the above by 100:

[tex]\implies \sf 100x=29.292929...[/tex]

To solve these two equations and write x as a fraction, subtract the first equation from the second to remove all the recurring digits after the decimal point:

[tex]\begin{array}{r r c l}& \sf 100x &= &\sf 29.292929...\\- & \sf x&=& \sf \phantom{..}0.292929...\\\cline{1-4} & \sf 99x&=& \sf29\\\cline{1-4}\end{array}[/tex]

Therefore:

[tex]\implies \sf 99x=29[/tex]

[tex]\implies \sf x=\dfrac{29}{99}[/tex]

Therefore:

[tex]\sf \implies 0.\overline{29}=\dfrac{29}{99}[/tex]

Answer:

-3=x

Step-by-step explanation:

3(x+4)-5=2x+4

use distributive property to get:

3x+12-5=2x+4

simplify to get:

3x+7=2x+4

subtract 4 from both sides to get:

3x+3=2x

subtract 3x from both sides to  get:

The 2nd option does not represent a function.

A function is a relation in which no two ordered pairs have the same first component and different second components.

We need to ask ourselves, does every first element (or input) correspond with EXACTLY ONE second element (or output)? 

In this case, the answer is no.  The input value of 1 goes with two output values, -1 and -5.   The same goes with the input value of 2, which also goes with two output values: -2 and -4.

It only takes one input value to associate with more than one output value to be invalid as a function.

I also did the Vertical Line Test to show why Option 2 is not a function. The Vertical Line Test allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function.

However, the graph shows that the two vertical lines crossed the graphed twice (there are 2 points in each line). The graphed points failed the vertical line test. Therefore, Option 2 is NOT a function.

Richard and Teo have a combined age of 31. Richard is 13 years older than twice​ Teo's age. How old are Richard and​ Teo?

Answers

Answer:Teo is 6 and Richard is 25

Step-by-step explanation:  Let R and T stand for Richard and Teo's ages.  We are told:

R+T=31

R=2T+13

Substitute:  

R+T=31

2T+13+T=31

3T+13=31

3T=18

T=6  

Since R+T=31, R+6=31, and R = 25

1.21 rounded to the nearest whole number​

Answers

1.2

1 is the whole number and to round you look one place over, in this case the number one over to the left if 2. If the number to the left is 5 or more you “raise the score” making the number your rounded go up one. If the number is 4 or less, you “let it rest” meaning the number stays the same. Once you round, you drop every number behind the number you used to round. So instead or 1.21 it’s 1.2

How do you get 60cm2 in question 1?

Answers

Answer:

Step-by-step explanation:

4*2=8, thats one rectangle (side)

8*2 is 16, thats TWO rectangles (sides)

7*4=28, thats one rectangle (front)

28*2=56, thats TWO rectangles (front and back)

7*2=14, thats one rectangle (top)

14*2=28, thats TWO rectangles (top and bottom)

add all of these surface areas together

TWO rectangles + TWO rectangles + TWO rectangles

28+56+16=100

As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape

Find the equation (in terms of x) of the line through the points (-2,3) and (4,-9)

Step-by-step explanation:

−16

0

y=mx+b

5=(0)(7)+b

b=5

therefore y = 5

Answer:  y = -2x - 1

Step-by-step explanation:

We can calculate the slope from the two given points.  Slope is the change in y per the change in x, sometimes called the rise (y) over the run (x)

Rise is (-9 -3) = -12

Run is (4 - (-2)) = 6

Slope = Rise/Run = -12/6 = -2

The line is y = -2x + b

Find b by using either of the two known points (solutions).  I'll choose (-2,3) [because I like smaller numbers]

y = -2x + b

3 = -2*(-2) + b

b = -1  [That was only slightly easier than -9 = -2*(4) + b; b = -1]

The equation is y = -2x - 1
