A farmer decides to take up breeding cows. He decides he will buy 7 more cows each year.
After 20 years, he has 340 cows. How many cows did he start with?

Answers

Answer 1

Answer:

200 cows

Step-by-step explanation:

7n+x=340 where n equals the number of years and x is the starting amount. Since he has been buying cows for 20 years, we plug 20 in for n. This would give you 140+x=340. After subtracting 140 from both sides you come to the conclusion that x=200.

Answer:

64 ounce bottle of orange juice  has a greater percent of water

Step-by-step explanation:

Case 1) An 80 ounce bottle of apple juice contains 32 ounces of water

Total quantity of bottle = 80 ounces

Amount of water = 32 ounces

So, Percent of water = [tex]\frac{32}{80}[/tex] x 100

                                 = 40%

Case 2) An 64 ounce bottle of orange juice has 48 ounces of water

Total quantity of bottle = 64 ounces

Amount of water = 48 ounces

So, Percent of water = [tex]\frac{48}{64}[/tex] x 100

                                 = 75%

Hence 64 ounce bottle of orange juice  has a greater percent of water

Given that;

The snail take 10 seconds to move 1 centimeter distance.

Now,

For covering 2.5 centimeters , the time is calculated as;

Since,

The snail take 10 seconds to move 1 centimeter distance.

That is,

⇒ 1 centimeter = 10 seconds

Hence, For the distance 2.5 centimeter, the time is;

⇒ 1 centimeter = 10 seconds

⇒ 2.5 centimeter = 2.5 × 10 seconds

A semicircle with diameter 8 inches is connected to a triangle with a base length of 8 inches. The height of the triangle is 3 inches.
What is the area of the composite figure?

Answers

Answer:

Step-by-step explanation:

Area of the semicircle = pi * r^2 / 2

d = 8

r = d/ 2

r = 8/2 = 4 inches

Area = pi * 4^2 / 2

Area = 3.14 * 8

Area = 25.12 square inches

Area of the triangle

Area = 1/2 * b * h

b = 8

h = 3

Area = 1/2 * 8 * 3

Area = 12 square inches

Total area = 25.12 + 12

Total area = 37.12 square inches

What is the value of the x variable in the solution to the following system of equations?
2x - 3y = 3
5x - 4y = 4

Answers

Answer:

x = 0

Step-by-step explanation:

Solve 2x - 3y = 3 for x:

[tex]2x - 3y = 3[/tex] [tex]2x - 3y + 3y = 3+ 3y[/tex]  (add 3y to both sides)[tex]2x = 3y + 3[/tex] [tex]\frac{2x}{2} = \frac{3y+3}{2}[/tex] (divide both sides by 2)[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex]

Substitute 3/2(y) + 3/2 for x in 5x - 4y = 4

[tex]5x - 4y = 4[/tex] [tex]5(\frac{3}{2}y + \frac{3}{2}) - 4y = 4[/tex] [tex]\frac{7}{2}y + \frac{15}{2} = 4[/tex] (simplified both sides of equation)[tex]\frac{7}{2}y + \frac{15}{2} - \frac{15}{2} = 4 - \frac{15}{2}[/tex] (subtract 15/2 from both sides)[tex]\frac{7}{2}y = -\frac{7}{2}[/tex] [tex]\frac{7}{2}y * \frac{2}{7} = \frac{-7}{2} * \frac{2}{7}[/tex] (multiply both sides by 2/7)[tex]y = -1[/tex]  

Substitute -1 for y in x = 3/2(y) + 3/2

[tex]x = \frac{3}{2}y + \frac{3}{2}[/tex] [tex]x = \frac{3}{2}(-1) + \frac{3}{2}[/tex] [tex]x = -\frac{3}{2}+ \frac{3}{2}[/tex] (simplified both sides of equation)[tex]x = 0[/tex]

Therefore, the value of the x-variable is 0.
