Step-by-step explanation:

In general, the only way to divide a square array of dots into two triangular arrays of dots is the way it was done in the example shown in the problem statement. The dividing line is drawn next to the longest diagonal.

So, for 25 dots, you make a 5×5 array and draw the line next to the corner-to-corner diagonal. Same for a 6×6 array of 36 dots.

Answer: x = 56

It’s a supplementary angle

Step-by-step explanation:

It’s a supplementary angle if their measures add to 180 degrees

is the equation

2x + 68 = 180 degrees

2x = 180 -68

2x = 112

x = 112/2

x = 56

Answer:

The length of one of it's sides is 4

Step-by-step explanation:

4 x = 16 x 4 = 64

A cube is a 3 dimensonal square, meaning the lenght, widith, and height of the cube are all going to be teh same.

Answer:

Step-by-step explanation:

Prime factorize 64

Volume of cube = 64 in³

side³ = 64

         = 2*2*2*2*2*2

Take cube root,

[tex]\sqrt[3]{side*side*side} =\sqrt[3]{2*2*2 * 2*2*2}\\\\\\side= 2* 2\\\\side = 4 \ in[/tex]

Step-by-step explanation:

If two planes intersect, they intersect in a line. The line and the plane intersect in a single point. The line and the plane do not interesect. In this case they are called parallel.

Answer: y=8x

Step-by-step explanation:

Slope-intercept form is y=mx+b, where m is slope and b is y-intercept. To find slope, we take any two points and plug them into [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]. Let's use (1,8) and (2,16).

[tex]m=\frac{16-8}{2-1}=\frac{8}{1} =8[/tex]

Now, we know that m=8. Looking at the graph, we can see that the y-intercept is b=0 because the line passes through the y-axis at (0,0). To be sure, let's plug in a point into our equation to see if the y-intercept is correct.

y=8x+b          [plug in (1,8)]

8=8(1)+b       [multiply]

8=8+b           [subtract both sides by 8]

b=0

Therefore, our equation is y=8x.

Answer:

3/5

Step-by-step explanation:

3 divided by 5 is 0.6, which translates to 60%.

55.5% < 60%

Answer:

3/5 is the greater .

I hope it will help you. Have a great day ahead.

Answer:

11/5

Step-by-step explanation:

FirLet a and b be the roots of 11x^2-4x-2=0

Now[tex](1+a+a^2+\cdots)(1+b+b^2+\dcots)=\frac{1}{1-a}\cdot \frac{1}{1-b}\\=\frac{1}{(1-a)(1-b)}=\frac{1}{1-(a+b)+ab}[/tex]

Dividing the quadratic equation by 11 we have

[tex]x^2-\frac{4}{11}x-\frac{2}{11}=0.[/tex]

Now the sum of the roots is the minus of the coefficient of x and the product of the roots is the constant. Therefore

[tex]a+b = 4/11 \\ab = -2/11[/tex]

and we have

[tex]\frac{1}{(1-a)(1-b)}=\frac{1}{1-\frac{4}{11}-\frac{2}{11}}\\=\frac{1}{(5/11)}=\frac{11}{5}[/tex]

Answer:

well for Evey 4 completed throws she takes 7 throws

with this ratio we get that;

it's 4:7

there fore

for 12 completed free throws she would take 21 free throws

option c is the answer

hope it's helpful

Answer:

21

Step-by-step explanation:

FreeThrows: FT

Attempted Throws: AT

FT/AT=4/7

12/AT=4/7

84/4=AT

AT=21

Answer:

12x² - 5x - 2

Step-by-step explanation:

(3x - 2)(4x + 1)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(4x + 1) - 2 (4x + 1) ← distribute parenthesis

= 12x² + 3x - 8x - 2 ← collect like terms

= 12x² - 5x - 2

Answer:

42.85 or 43 percent

Step-by-step explanation:

16 + 12 = 28

12/28 = x/100

12(100) = 28x

1200 = 28x

1200/28 = 28x/28

x = 42.85

Answer:

AD=6

Step-by-step explanation:

If AB=CD then 2x+8=4x+6, this can be rearranged to get 8-6=4x-2x or 2=2x or x=1.

AD=AB+BC+CD or AD=(2x+8)+(x-3)+(4x-6) this can be rearranged as AD=(2x+x+4x)+(8-3-6) or AD=7x-1 and we know x=1 so AD=6.

Step-by-step explanation:

=8x-12 > 8x+8

=x -(-4)

Answer:

x=1

y=-4

Step-by-step explanation:

Since -x-3=y subsitue that in at the top equation

[tex] - x - 3 = - 7x + 3[/tex]

[tex] - x = - 7x + 6[/tex]

[tex]6x = 6[/tex]

[tex]x = 1[/tex]

Plug x=1 back into the equation to solve for y.

[tex]y = - 7(1) + 3[/tex]

[tex]y = - 4[/tex]
