Answer:

Tanisha = 14 years

Ana = 7 years

Elicia = 16 years

Step-by-step explanation:

Let T = age of Tanisha

Let A = age of Ana

Let E = age of Elicia

Tanisha is twice as old as Ana:  

T = 2A

⇒ A = (1/2)T

Elicia is 2 years older than Tanisha:

E = 2 + T

Sum of all their ages is 37:

A + E + T = 37

Substitute A = (1/2)T and E = 2 + T into A + E + T = 37 and solve for T:

⇒ (1/2)T + 2 + T + T = 37

⇒ (5/2)T = 35

⇒ T = 14

If T = 14, then

A = (1/2)T = (1/2) 14 = 7

If T = 14, then

E = 2 + T = 2 + 14 = 16

You cut a pizza cut into 2 equal slices and eat 1 slice, or 1/2

of the pizza. You cut another pizza of the same size cut into 4

equal slices, but you still only eat 1 slice. This time you've

eaten only 1/4 of the pizza, which is less than 1/2.

As you divide the pizza into more slices, the bottom number

(the denominator) gets bigger, but the size of each slice gets

smaller.

Answer:

The width of the fence measures 6 feet

Step-by-step explanation:

Firstly, we assign variables.

Let the width of the fence be represented by w and the length by l

Now let’s get what the length would be. width is 2 less than half length

w = l/2 - 2

or simply l/2 = w + 2

which is same as l = 2(w + 2)

Now the perimeter of the fencing is 44. The perimeter of a rectangle can be calculated using the formula

P = 2(l + w)

Now let’s insert what we have:

P = 44 and l = 2(w + 2)

44 = 2(2(w+2) + w)

44 = 2(2w + 4 + w)

44 = 2(3w + 4)

44 = 6w + 8

6w = 44-8

6w = 36

w = 36/6

w = 6 feet

Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is  C

Step-by-step explanation:

From the question we are told that

    The number of outcome is  3 (rock paper and scissors)

     The number of game you and the first friend played is  a = 400

      The number of times friend A chose scissors is b = 100

      The number of game you and the second friend played is c= 120

       The number of times friend B chose scissors  is  d =  20

        The number of game you and the third friend played is e =  300

        The number of times friend B chose scissors  is f = 65

Generally the probability of success of each outcome is  

        [tex]p = \frac{1}{3} = 0.33[/tex]

Generally the probability of failure of each outcome is  

      [tex]q = 1-p[/tex]

=>   [tex]q = 1-\frac{1}{3}[/tex]

=>    [tex]q = \frac{2}{3} = 0.67[/tex]

Generally the proportion of  scissors chosen by friend A is  mathematically represented as

        [tex]p_1 =  \frac{b}{a}[/tex]

=>       [tex]p_1 =  \frac{100}{400}[/tex]

=>       [tex]p_1 = 0.25[/tex]

Generally the proportion of  scissors chosen by friend B is  mathematically represented as

        [tex]p_2 =  \frac{d}{c}[/tex]

=>       [tex]p_2 =  \frac{20}{120}[/tex]

=>       [tex]p_2 = 0.167[/tex]

Generally the proportion of  scissors chosen by friend B is  mathematically represented as

        [tex]p_3 =  \frac{f}{e}[/tex]

=>       [tex]p_3 =  \frac{65}{300}[/tex]

=>       [tex]p_3 = 0.2167[/tex]

Generally the standardized value  for  friend A is mathematically represented as

          [tex]z_1 =  \frac{p_1 - p}{\sqrt{\frac{p* q}{a} } }[/tex]

     => [tex]z_1 =  \frac{0.25- 0.33}{\sqrt{\frac{0.33* 0.67}{400} } }[/tex]

      =>  [tex]z_1 = -3.4[/tex]      

Generally the standardized value  for  friend B is mathematically represented as

          [tex]z_2 =  \frac{p_2 - p}{\sqrt{\frac{p* q}{c} } }[/tex]

     => [tex]z_2 =  \frac{0.167- 0.33}{\sqrt{\frac{0.33* 0.67}{120} } }[/tex]

      => [tex]z_2 =  -3.8 [/tex]      

Generally the standardized value  for  friend C is mathematically represented as

          [tex]z_3 =  \frac{p_3 - p}{\sqrt{\frac{p* q}{e} } }[/tex]

     => [tex]z_3 =  \frac{0.2167- 0.33}{\sqrt{\frac{0.33* 0.67}{300} } }[/tex]

      => [tex]z_3 =  -4.17 [/tex]            

Answer: C

reason: There are special rules to follow when an expression is raised to the power of 0 or 1. Remember these rules when using numerical expressions involving the exponents 0 and 1:

Any number raised to the power 0 is equal to 1. For example, 120 is equal to 1 and 300 is equal to 1. However, this rule does not apply when 0 is the base: 0 raised to any power other than 0 is equal to 0, and 00 is not defined.

Any number raised to the power 1 is equal to the number itself. For example, 121 is equal to 12, 301 is equal to 30, and 01 is equal to 0

A numerical expression contains numbers and operations but not the equality symbol (=). Here are some examples of numerical expressions:

15 + 4 − 2

56 ÷ 7 + 5 × 5 × 5

32 × 5 + 7

Numerical expressions can also be written in words, such as "nine times six minus seven" and "five divided by ten plus two."

Look at the expression 56 ÷ 7 + 5 × 5 × 5. Instead of writing 5 three times in the expression, we can replace it with a whole-number exponent. For that, we write 5 × 5 × 5 as 53:

56 ÷ 7 + 5 × 5 × 5

56 ÷ 7 + 53.

Let's write 2 × 3 × 3 × 3 × 3 × 3 × 3 with a whole-number exponent. Here, 3 is multiplied by itself and occurs 6 times in the expression. Instead of writing 3 six times, we can write 3 × 3 × 3 × 3 × 3 × 3 as 36. So, 2 × 3 × 3 × 3 × 3 × 3 × 3 is the same as 2 × 36.

In Ascending order=22,39,50,61,77,88,89

The Product Rule: If there are n(A) ways to do A and n(B) ways to do B, then the number of ways to do A and B is n(A) × n(B). This is true if the number of ways of doing A and B are independent; the number of choices for doing B is the same regardless of which choice you made for A.

Answer:

f(x) = -5/3 x +44/3

Step-by-step explanation:

helo :   let  f(x)= ax+b

f(4) = 8   means : a(4)+b=8 and f(7) = 3   means : a(7)+b=3

you have this system :  4a +b = 8....(*)

                                      7a+b = 3 ....(**)

solve this system  use (*) : b = 8 -4a   and use (**) : b = 3-7a

so : 8-4a = 3-7a

-4a+7a = 3-8

3a = -5   so a = -5/3

but b =8-4a     so : b= 8-4(-5/3) =8+20/3  =44/3

f(x) = -5/3 x +44/3

Answer:

Step-by-step explanation:

to get the area of the given figure,

we need to split it in to two (see attached)

then area of a rectangle = length x width

A1 = 15 cm x 4 cm = 60 cm²

A2 = 5 cm x 4 cm = 20 cm²

Area = A1 + A2

        = 60 + 20

        = 80 cm²

Area in this figure will be 80cm².

The area of the rectangle can be calculated by the product of length and breadth of the rectangle.

A=l*b

where l is length and b is the breadth.

So according to asked question in the drawn figure,

connect the point B and G.

now this figure will give two rectangle i.e. ABGH and CDEF

Rectangle ABGH has length l=5cm

breadth b=4cm

area of the rectangle ABGH= length * breadth=l*b=5*4=20cm²

Now CF=CB+BG+GF=5+5+5=15

Rectangle CDEF has length l=CF=15cm

breadth b=4cm

area of the rectangle ABGH= length * breadth=l*b=15*4=60cm²

Area of the figure= area of the rectangle ABGH+area of the rectangle CDEF

=20cm²+60cm²

=80cm²

Therefore area in this figure will be 80cm².

Answer:

D) Graph Z

Step-by-step explanation:

Convert from point-slope to slope-intercept form

[tex]y-6=4(x-4)\\\\y-6=4x-16\\\\y=4x-10[/tex]

This tells us that the line intersects the y-axis at (0,-10) and that our slope is 4. Therefore, the best choice given the options is D, graph Z.

The linear equation y = 4x - 10 represents the graph z. Then the correct option is D.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The linear equation is given below.

y - 6 = 4(x - 4)

Convert the equation into slope-intercept form. Then we have

y - 6 = 4(x - 4)

y - 6 = 4x - 16

y = 4x - 16 + 6

y = 4x - 10

The slope of the line is 4 and the y-intercept of the line is negative 10. Then the equation represents the graph z, then option D is correct.

[tex]m = \frac{4}{3} = 1.3334[/tex]

Step-by-step explanation:

To find the slope of a line, all you have to do is determine 2 points that pass through this line;

for example, in this case,

(-4,-2) (4,4)

Use the equation;

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{4 - ( - 4)}{4 - ( - 2)} = \frac{4 + 4}{4 + 2} [/tex]

[tex]m = \frac{8}{6} = \frac{4}{3} [/tex]

This line passes through the point (1,0) and that is your y-intercept.

[tex]y = \frac{4}{3} x + 1[/tex]

The requried slope of the given line is m = 3/4.

The slope of the line is defined as the ratio of the rise and run of the straight line on the curve is given as;

m = (y₂ - y₁) / (x₂ - x₁)

Here,
From the graph, we have (-4, -2) and (4, 4).

The slope of the line is given as:

m = (y₂ - y₁) / (x₂ - x₁)

m = (4+2)/(4+4)
m = 6/8
m = 3/4

Thus, the requried slope of the given line is m = 3/4.

Answer:

Step 1) Rotate 90 degrees counterclockwise around the origin

Step 2) Shift 5 units down

=======================================================

Explanation:

Focus on one of the corner points of figure S.

I'll focus on (9,1)

Apply a 90 degree counterclockwise rotation on this point, and rotate it around the origin.

The rotation rule is [tex](x,y) \to (-y,x)[/tex]

This means [tex](9,1) \to (-1,9)[/tex] meaning (9,1) rotates to (-1,9)

Notice that (9,1) on figure S corresponds to (-1,4) on figure T.

This means after arriving to (-1,9), we need to somehow apply a shifting translation to get to (-1,4)

To get from (-1,9) to (-1,4) we shift the point down 5 units.

-----------------------

To recap:

If you apply that rotation and shifting rule to each of the four corner points of figure S, then you'll end up with figure T.

Figure S is known as the preimage while figure T is the image.
