Answer:

\$45

Step-by-step explanation:

we know that

5 boxes of cereal costs $12.50

so

Using proportion

Find how much will 18 boxes cost

Let

x -----> the cost of 18 boxes

\frac{12.5}{5}\frac{\$}{boxes}=\frac{x}{18}\frac{\$}{boxes}\\ \\x=12.5*18/5\\ \\x=\$45

A firm manufactured 1000 Tv sets during its first yeae the total firns production during 10 years of operation is 29035 sets If
Alexus [3.1K]

Answer: the increase each year is 423 tv sets

Step-by-step explanation:

The formula for determining the sum of n terms of an arithmetic sequence is expressed as

Sn = n/2[2a + (n - 1)d]

Where

n represents the number of terms in the arithmetic sequence.

d represents the common difference of the terms in the arithmetic sequence.

a represents the first term of the arithmetic sequence.

From the information given,

n = 10 years

a = 1000

S10 = 29035

We want to determine d which is the amount by which the production increased each year. Therefore, the sum of the first 10 years would be

29035 = 10/2[2 × 1000 + (10 - 1)d]

29035 = 5[2000 + 9d]

29035/5 = [2000 + 9d]

9d = 5807 - 2000 = 3807

d = 3807/9 = 423

Find all the missing angles: a, b, c, d.
morpeh [17]

Answer:

a= 180-60-55=65

we know that the angle of a flat(?) ground would be 180, so we can take away the 60 and 55 to find a.

b=180-90-65=25

the sum of interior angle of a triangle would be 180, now we know what a is, also the right angle is 90, now we can take away the 90 and 65 to find b.  

c=25

c is 25, because two angles on both sides of a X is the same

Share 800 in the ratio 9:7.
bulgar [2K]

<u>Answer:</u>

  • The numerator '9's share is 450 and the denominator '7's share is 350.

<u>Step-by-step explanation:</u>

<u>Step-1: Add the ratios:</u>

  • 9 + 7
  • 16

<u>Step-2: Divide 800 by the sum of the ratios:</u>

  • 800 ÷ 16
  • => 50

<u>Step-3: Multiply 50 with each ratio:</u>

  • 9 x 50 = 450
  • 7 x 50 = 350

Hence, <u>the numerator '9's share is 450 and the denominator '7's share is 350.</u>

Hoped this helped.

Subtract (4x2 - x + 6) from (3x2 + 5x - 8).
bearhunter [10]

Step-by-step explanation:

(4x^2-x+6)-(3x^2+5x-8)=4x^2-x+6-3x^2-5x+8

By simplifying the right side of the equation, we come up with

x^2+6x-14, or D
