Answer:

For a=0.9876 and b=0.9887 mid point will be 0.98815

Step-by-step explanation:

We have given a = 0.9876 and b = 0.9887

And N = 2

We have to find the mid point

For finding mid point we know that formula

Midpoint =\frac{a+b}{2} , here we have given a=0.9876 and b = 0.9887

So midpoint will be =\frac{0.9876+0.9887}{2}=\frac{1.9763}{2}=0.98815

So for a=0.9876 and b=0.9887 mid point will be 0.98815

What is the ratio from 18 to 16
Irina18 [472]

Answer: 8:9

Step-by-step explanation: Two find this answer, you need to see what will be the greatest number they can divide by (greatest common divider), it needs to be the same number for both 18 and 16. What number can go into both numbers, and is the greatest number? The answer is two, now you divide 2 by 18 and 16, so you'll get 8:9.

Hope this helps have a BLESSED and wonderful day! :-)

Answer: Part a) 375 pounds, Part b) 8 words

Step-by-step explanation:

a)

<u />

Since n represents the number of words there are, we can plug in 20 for n into the equation to get:

C = 15*20 + 75 pounds

C = 300 + 75 pounds

C = 375 pounds

b)

Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:

195 = 15n + 75

Subtract 75 from both sides:

120 = 15n

Divide both sides by 15:

n = 8 words

Subtract: (x^2 - 8x + 5)-(-3x^2 + 5x-9)
Marianna [84]

Answer: 4x^2 -13x + 14

Step-by-step explanation:

(x^2 - 8x + 5)-(-3x^2 + 5x-9)

Subtract -3x^2 from x^2

(4x^2 - 8x + 5)-(5x-9)

Subtract 5x from -8x

(4x^2 -13x + 5)-(-9)

Subtract 9 from 5

4x^2 -13x + 14

Tess needs to buy sand for her children’s playground. The sand costs $8 per ton, and there is a delivery cost of $50 with each o
Butoxors [25]

Answer:

All positive rational numbers greater than 50

Step-by-step explanation:

Since the delivery cost is fixed per trip, the cost incurred can be represented by the equation

y(x)=8x+50 so in case Tess wants only 1 tone, the cost will be y(x)=8(1)+50=58

Therefore, it's proper to conclude that all numbers in the possible range are positive rational numbers greater than 50

Answer:

  • 6 ≤ x ≤ 12

Step-by-step explanation:

<u>Area formula</u>

  • A = lw

<u>Applied to the given rectangle, we have</u>

  • A = 1.5*4x = 6x

<u>Since 36 ≤ A ≤ 72, substituting A</u>

  • 36 ≤ 6x ≤ 72
  • 6 ≤ x ≤ 12

It is viable.
