Is point (20,15) on line j?

Answer:

x = 7

Step-by-step explanation:

From the above question, we are told that:

∠A and ∠B vertical angles.

It is important to note that vertical angles are equal to each other

Hence:

∠A = ∠B

From the question,

∠A = (5x−2)°

∠B = (3x+12)°

Hence:

(5x−2)°= (3x+12)°

5x - 2 = 3x + 12

Collect like terms

5x - 3x = 12 +2

2x = 14

x = 14/2

x = 7

Answer:

X=14

Answer: 35%

Step-by-step explanation:

You did not give the numbers. Let me help out by giving some figures and explain with that.

Latoya needs to make a total of 60 deliveries this week. So far she has completed 21 of them. What percentage of her total deliveries has Latoya completed?

To solve this, we divide 21 by 60 and then multiply by 100. This will be:

= (21 / 60) × 100

= 7/20 × 100

= 35%

Answer: C.[tex]\left \{ {{a1=-2} \atop {an=a(n-1)+3}} \right.[/tex]

because it is the arithmetic progression with d = 3

=> a(n) = a1 + (n - 1).3

so, have: a1 = -2

               an = a(n-1) + 3

Answer:

The slope of the line that contains diagonal OE will be = -3/2

Step-by-step explanation:

We know the slope-intercept form of the line equation

y = mx+b

Where m is the slope and b is the y-intercept

Given the equation of the line that contains diagonal HM is y = 2/3 x + 7

y = 2/3 x + 7

comparing the equation with the slope-intercept form of the line equation

y = mx+b

Thus, slope = m = 2/3

As we have to determine the slope of the line that contains diagonal OE.

As the slope of the line that contains diagonal HM = 2/3

We also know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line.

Therefore, the slope of the line that contains diagonal

OE will be = -1/m = -1/(2/3) = -3/2

Hence, the slope of the line that contains diagonal OE will be = -3/2

Answer:

what

Step-by-step explanation:

The Slope of line (1, 1) and (3, 9) is 4.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

The Figure of the graph is attached below.

We have the Coordinates as (1, 1) and (3, 9).

So, the slope of line

= (9- 1)/ (3-1)

= 8/ 2

= 4

Thus, the slope of line is 4.

2.5 cups of milk

Step-by-step explanation:

Given that,

A cake recipe calls for 1.5 cups of milk and 3 cups of flower.

Seth made a mistake and used 5 cups of flour.

We need to find number of cups of milk he use to keep the proportions correct. Let he used x cups of milk.

[tex]\dfrac{1.5}{3}=\dfrac{x}{5}\\\\x=\dfrac{1.5\times 5}{3}\\\\x=2.5[/tex]

Hence, he should use 2.5 cups of milk.

The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Step-by-step explanation:

Let suppose that effects from air friction and Earth's rotation can be neglected, so that the softball can be modelled experiment a free fall, that is, an uniform accelerated motion due to gravity. From we know the initial velocity and position of the position and we can determine the final position of the ball as a function of the final velocity:

[tex]v_{f}^{2} = v_{o}^{2}+2\cdot a \cdot (s_{f}-s_{o})[/tex] (1)

Where:

[tex]s_{o}[/tex], [tex]s_{f}[/tex] - Initial and final position of the softball, measured in feet.

[tex]a[/tex] - Acceleration, measured in meters per square second.

[tex]v_{o}[/tex], [tex]v_{f}[/tex] - Initial and final velocities of the softball, measured in feet per second.

If we know that [tex]v_{o} = 50\,\frac{ft}{s}[/tex], [tex]a = -32.174\,\frac{m}{s^{2}}[/tex] and [tex]s_{o} = 4\,ft[/tex], then the equation that models the situation is:

[tex]v_{f}^{2} = 2500-64.348\cdot (s_{f}-4)[/tex]

Then, we clear the final position of the softball:

[tex]-\frac{v_{f}^{2}-2500}{-64.348} = s_{f}-4[/tex]

[tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex]

The equation that models the situation is [tex]s_{f} = 4+\frac{v_{f}^{2}-2500}{64.348}[/tex].

Answer:

B. 36 C. 180 D. 240 E. 1,656

Step-by-step explanation:

Partial product is the multiplication of individual digit of a number in turn with each digit of the others where each digit maintains its place.

Using distributive property to multiply 24 × 69 to determine our partial products:

i.e.

24 × 69 = 24 × (60 + 9)

= (24 × 60) + (24 × 9)

= 60 (20 + 4) + 9(20 + 4)

So; we can have:

= (60 × 20) + (60 × 4) + (9 × 20) + (9 × 4)

= 1200 + 240 + 180 + 36  

= 1656

[tex]70\ \text{kilometers}[/tex]

Step-by-step explanation:

The scale of the map is 1 centimeter distance on the map represents 20 kilometers of actual distance.

The distance between the two cities is 3.5 centimeters on the map

[tex]1\ \text{centimeters on the map}=20\ \text{kilometers of actual distance}[/tex]

So,

[tex]3.5\times 20=70\ \text{kilometers}[/tex]

So, the distance between the two cities is [tex]70\ \text{kilometers}[/tex].
