read the text wrong. but the method below holds :D

Step-by-step explanation:

The intersection of the AC line with the BD line is at (1,3)

method: hold an old receipt on my phone screen. would describe it as a graphically approach to the solution

on paper a ruler would be enough to draw the two mentioned lines.

do you need an algebraic way to do it?

Answer:

Subtract the area of the semicircle from the area of the rectangle

Step-by-step explanation:

Hi there!

1) Find the area of the rectangle

[tex]A=lw[/tex]

Plug in the given side lengths 10 and 8 and solve for the area of the rectangle. Disregard the semicircle.

2) Find the area of the semicircle

[tex]A=\pi r^2[/tex]

Divide 8 by 2 to find the radius and solve for the area of the circle. Divide this by 2 to represent the semicircle.

3) Subtract the area of the semicircle from the area of the rectangle

[tex]A_r_e_c_t_a_n_g_l_e-A_s_e_m_i_c_i_r_c_l_e=A_p_o_o_l[/tex]

I hope this helps!

Answer:

bring the lines side by side ( example || )

Step-by-step explanation:

Answer:  [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex]

The sin(A) goes with 'a'

sin(B) goes with b

sin(C) goes with c

Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as [tex]\frac{a}{\sin(A)} = \frac{b}{\sin(B)}[/tex] and [tex]\frac{b}{\sin(B)} = \frac{c}{\sin(C)}[/tex] and [tex]\frac{a}{\sin(A)} = \frac{c}{\sin(C)}[/tex]

Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.

Answer:

1) 5, 7, 8

2) 10, 24, 26

Step-by-step explanation:

1) For an acute triangle, the square of the longest side is less than the sum of the square of the two smaller sides.

a) 4² + 5² = 16 + 25 = 41

7² = 49 > 4² + 5².  Therefore the triangle is not acute

b) 5² + 7² = 25 + 49 = 74

8² = 64 < 5² + 7².  Therefore the triangle is acute

c) 6² + 7² = 36 + 49 = 85

10² = 100 > 6² + 7².  Therefore the triangle is not acute

d) 7² + 9² = 49 + 81 = 130

12² = 144 > 7² + 9².  Therefore the triangle is not acute

2) For a right angled triangle, the square of the longest side is equal to the sum of the square of the two smaller sides.

a) 8² + 12² = 64 + 144 = 208

15² = 225 > 8² + 12².  Therefore the triangle is not a right triangle.

b) 10² + 24² = 100 + 576 = 676

26² = 676 = 10² + 24².  Therefore the triangle is a right triangle.

c) 20² + 12² = 400 + 144 = 544

25² = 625 > 20² + 12².  Therefore the triangle is not a right triangle.

d) 15² + 18² = 225 + 324 = 549

20² = 400 < 15² + 18².  Therefore the triangle is not a right triangle.

[tex]x=2+½*\sqrt{10} [/tex]

or

[tex]x=2-½*\sqrt{10} [/tex]

Answer:

Solution given:

y=2x²-5x+6.....[1]

y=3x+3.........….[2]

solving equation 1&2

2x²-5x+6=3x+3

2x²-5x-3x+6-3=0

2x²-8x+3=0

comparing above equation with ax²+bx+c=0 we get

a=2

b=-8

c=3

by using quadratic equation

[tex]x=\frac{+8±\sqrt{(-8)²-4*2*3}}{2*2}[/tex]

[tex]x=\frac{+8±2\sqrt{10}}{4}[/tex]

taking positive

[tex]x=\frac{+8+2\sqrt{10}}{4}[/tex]

[tex]x=2+½*\sqrt{10} [/tex]

taking negative

[tex]x=2-½*\sqrt{10} [/tex]

Answer:

x<5

Step-by-step explanation:

since the CD is a one time purchase, his total amount of money after would be 25.

40-15>6x

25>6x (still have to solve for x)

4.166>x

x<5 (since it has to be a whole number)

Answer:

y = 3x - 1

Step-by-step explanation:

→ Substitute x = 1 into all the equations to get y = 2

y = 3x - 1 ⇔ ( 3 × 1 ) - 1 = 2

Answer:

D

Step-by-step explanation:

You can answer this question without even worrying about slope if you know how the y-intercept should be. The y-intercept is where the line crosses the y-axis(the vertical line with the y label in case that needs to be explained.) With that alone, you can determine that the y-intercept is -1 and thus the answer is D. For the slope, try to find a point on the line that is on the grid (A good one is (0,-1) ). Then move from that point to the next point where two of the lines meet like (1,2). Slope is rise/run so you go 3 up and 1 to the right for 3/1 which equals 3.

Answer:

(X,Y) is (20,10) so that mean he made 10 bucks and sold 20 cups

Step-by-step explanation:

Answer:

1/6

Step-by-step explanation:

6^-2  / 6^-1

We know that a^b / a^c = a^(b-c)

6^(-2 - -1) = 6^(-2+1) = 6^-1

We know that a^-b = 1/a^b

1 /6^1 = 1/6

Answer:

1/6

Step-by-step explanation:

When dividing by exponents, you need to subtract the exponent from top to bottom. Ex: 5^3/5^2=5^1 which is just one, because you subtract 3 and two. In this case, 6^-2 / 6^-1 gets us 6^-1 which is the same thing as 1/6^1. Because remember, a^-x = 1/a^x.

Answer:

Step-by-step explanation:

Point C represents the solution of the inequality graph

The graph shows two sets of equations

The first equation

This is represented by a dotted line because it does not have the equality sign. The sign represented is called the less than sign. The feature of being a dotted line helps in knowing the line that solves the equation.

Also. the solution of the less than sign is below the line this eliminates points B and A.

The second equation

This is represented by a solid line since it has the equality sign present. This is read as greater than or equal to. It has two signs joined together. The solution of the greater than sign is above the line this eliminates points  A and D

Hence points A, B, and D has been eliminated remaining point C hence point C represents the solution of the inequality graph

Answer: same distance but different side

Step-by-step explanation:

Answer:

$410

Step-by-step explanation:

Step 1

We calculate the amount of commission of sales

Commission rate = 10%

Total sales = $2100

Hence,

= 10% × $2100

= 10/100 × $2100

= $210

Step 2

The total pay of Clarence for that week

= Commission + Weekly salary

Commission = $210

Weekly salary = $200

Hence,

= $210 + $200

= $410
