the answer is:

4x + 4y + 7

Answer:

x = 22°

w = 30°

y = 30°

z = 52°

Step-by-step explanation:

From ΔACD,

AD is the diameter and ∠ACD is the angle subtended by the diameter.

Therefore, m∠ACD = 90°

By triangle sum theorem,

m∠DAC + m∠ACD + m∠CDA = 180°

w° + 90° + 60° = 180°

w = 180 - 150

w = 30°

AB║ED and AD is a transversal line.

Therefore, m∠BAD = m∠ADE

(w + 22)° = z°

30 + 22 = z

z = 52°

Since, ∠CEB and ∠BAC are the inscribed angles subtended by the same arc BC,

Therefore, m∠CEB = m∠BAC

x = 22°

Similarly, ∠CED and ∠DAC are the inscribed angles subtended by the same arc CD,

m∠CED = m∠DAC = 30°

y = 30°

C) Ratio of novels : children's books Saturday -> 18:25

D) Ratio of  cookbooks : novels Sunday -> 6:12 or 1:2

Ratios from options A) B) and C) are all larger than 1:2 (1/2 or 0.5)

Answer:

C

Step-by-step explanation:

There are many ways to figure it out but if you multiply by 20 each you'll get 40/100=40%

Answer:

c: 2/5

Step-by-step explanation

40% ÷10= 4÷2=2

100%÷10=10÷2=5

So you do 40% over 100% and divide both by 10 then simplify it and 2 goes into both 4 and 10 so you divide by 2 and get 2/5

Answer:

34

Step-by-step explanation:

Start by adding the number in the parenthesis: This gives us (8(11)/2^2) + 6(2)

Square the bottom: (8(11)/4) + 6(2)

Multiply the top of the fraction: (88/4) +6(2)

Divide 88 by 4: 22 + 6(2)

Multiply 6 and 2: 22 + 12

Add 22 and 12: 22 + 12 = 34

Answer: 34

Answer:

A normal is an object such as a line or vector that is perpendicular to a given object. ... If normal is 90 degree to the surface, that means normal is used in 3D. Perpendicular in that case is more in 2D referring two same entities (line-line) with 90 degree angle between them.

The value of x and y  for the given equation by elimination method are 1 and 1 respectively.

The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the given question

We have two equations

[tex]2x -y =1...(1)[/tex]

[tex]x+3y-4=0...(2)[/tex]

Multiply equation (1) both the sides by 3

[tex]6x - 3y =3...(3)[/tex]

Adding equation (2) and (3)

[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]

Substitute

x =1,  in either 2x -y =1 or x + 3y -4 =0

2(1) - y =1

⇒ -y = 1 -2

⇒ -y = -1

⇒ y =1

Hence, the value of x  and y is 1 and 1 respectively.

Answer:

These are the coordinate pairs: (0,0), (2,4), (3,6), (6,12)

Step-by-step explanation:

since y=2x, you just multiply every value for x by 2, so for the x values 0, 2, 3, and 6, you would get 0, 4, 6, and 12, respectively.

Sean drank slushy  8 ml per second.

The correct answer is an option (D)

"The slope of the line passing through points [tex](x_1,y_1),(x_2,y_2)[/tex] is,

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]"

For given question,

From the graph, we can observe the line is passing through points         (0, 600) and (75, 0)

Let [tex](x_1,y_1)=(600,0),(x_2,y_2)=(75,0)[/tex]

The slope of the line would be,

[tex]\Rightarrow m=\frac{y_2-y_1}{x_2-x_1}\\\\\Rightarrow m=\frac{0-600}{75-0}\\\\\Rightarrow m =\frac{-600}{75}\\\\ \Rightarrow m = -8[/tex]

This means, Sean drank slushy  8 ml per second.
