Answer: Percentage of 36% of 3.18 = 1.1448

Answer : 4/15

Step-by-step explanation:

Answer:

2/5

Step-by-step explanation:

2/15, 1/5, 4/15, 1/3

Get a common denominator

2/15, 3/15, 4/15, 5/15

We are adding 1/15 each time

The next term would be 6/15 which simplifies to 2/5

Answer:

i believe its 7 + x < 20

Step-by-step explanation:

The inequality function that represent the given statement should be 7 + x < 20. The second option is correct.

It is the relationship  type that shows the relationship with the graph.

Since the statement like

Seven more than a number, 2, is at most 20.

So its inequality function be like

7 + x < 20

hence, the second option is correct.

And, the rest of the options are incorrect.

Explanation:

I'm assuming tracking stations A and B are at the same elevation and are on flat ground. In reality, this is likely not the case; however, for the sake of simplicity, we'll assume this is the case.

The diagram is shown below. Points A and B describe the two stations, while point C is the satellite's location. Point D is on the ground directly below the satellite. We have these lengths

Focusing on triangle ACD, we can apply the tangent rule to isolate h.

tan(angle) = opposite/adjacent

tan(A) = CD/AD

tan(86.4) = h/x

x*tan(86.4) = h

h = x*tan(86.4)

We'll use this later in the substitution below.

--------------------

Now move onto triangle BCD. For the reference angle B = 85, we can use the tangent rule to say

tan(angle) = opposite/adjacent

tan(B) = CD/DB

tan(B) = CD/(DA+AB)

tan(85) = h/(x+60)

tan(85)*(x+60) = h

tan(85)*(x+60) = x*tan(86.4) .............  apply substitution; isolate x

x*tan(85)+60*tan(85) = x*tan(86.4)

60*tan(85) = x*tan(86.4)-x*tan(85)

60*tan(85) = x*(tan(86.4)-tan(85))

x*(tan(86.4)-tan(85)) = 60*tan(85)

x = 60*tan(85)/(tan(86.4)-tan(85))

x = 153.612786190499

--------------------

We'll use this approximate x value to find h

h = x*tan(86.4)

h = 153.612786190499*tan(86.4)

h = 2441.60531869599

h = 2441.61 km  is how high the satellite is above the ground.

Return to triangle ACD. We'll use the cosine rule to determine the length of the hypotenuse AC

cos(angle) = adjacent/hypotenuse

cos(A) = AD/AC

cos(86.4) = x/AC

cos(86.4) = 153.612786190499/AC

AC*cos(86.4) = 153.612786190499

AC = 153.612786190499/cos(86.4)

AC = 2446.43279498247

AC = 2446.43 km is the distance from the satellite to station A.

Answer:

-1 < m ≤ - 5

Step-by-step explanation:

Your expression includes: m, -1, -5, >, ≤

m is the value being compared so it will be in the middle.

# sign m sign #

m is no less than -1: no less than means it is greater than -1, but does not include -1. Therefore, our sign is >

m > -1

m is less than or equal to -5. This means we use ≤ because it can equal -5.

m ≤ -5

Now combine the two expressions

m > -1 – This can also be written as -1 < m.

m ≤ -5

-1 < m ≤ - 5

Answer:

400

Step-by-step explanation:

so the question is 20 times 20. This problem means you are doing 20, 20 times. Since you are in 3rd grade I will use the counting meathod. So to do this you need to count starting at 20 by 20 20 times.

20 40 60 80 100 120 140 160 180 200 220 240 260 280 300 320 340 360 380 400.

As you can see the answer is 400. I started at 20 and I consistently counted by 20. Also I did it 20 times. I did this because the problem says to do 20, twenty times.

Answer:

x = - 6, x² = [tex]\frac{7}{2}[/tex]

Step-by-step explanation:

[tex]2x^{2}[/tex] + 12x - 7x - 42 = 0

2x^{2} (x + 6) - 7 (x + 6) = 0

(x + 6) x (2x - 7) = 0

x + 6 = 0

2x - 7 = 0

x = - 6

x = [tex]\frac{7}{2}[/tex]

x = - 6, x² = [tex]\frac{7}{2}[/tex]
