What is the slope of the line?

"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.

The correct answer is an option (D)

Solve the system by elimination
2x – y=1
x + 3y – 4= 0

Answers

Did it step by step , hope it helps !

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

Elimination method for solving the system of equations;

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.

The lateral surface area of the triangular prism is

Explanation:

The side lengths of the base of the triangular prism are 5 meters, 8 meters, and 10 meters.

It is given that the height of the prism is 16.5 meters.

To determine the lateral surface area of the prism, let us use the formula

LSA = (a + b + c)h

where a, b,c are the side lengths of the base of the triangular prism and h is the height of the prism.

Here: a = 5, b = 10,c = 8 and: h = 16.5

Substituting these values in the formula, we have,

LSA = (5 + 10 + 8) 16.5

Simplifying, we get,

LSA = (23) 16.5

Multiplying, we get,

LSA = 379.5

Thus, the lateral surface area of the triangular prism is,

379.5sq. units

Find the slope of the line.

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

AD is a diameter of circle ABCDE . Angle BAC=22° & angle ADC=60°. AE and ED are parallel lines. Find the values of w, x,y,and z

Answers

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°
