A farmer notes that in a field full of horses and chickens there are 35 heads and 98 feet. How many of each animal are there?

Answers

Answer 1

Answer:

There are 14 horses and 21 chickens.

Step-by-step explanation:

First, you have to make expression for horse and chicken. So we can let x be the number of horses and y will be the number of chickens. Next, given that the total number of feet for both animals is 98 so you have to make simultaneous equation :

[tex]4x + 2y = 98[/tex]

( horse has 4 feet and chicken has 2 feet )

There are a total of 35 heads so the other equation will be :

[tex]x + y = 35[/tex]

Lastly, you have to solve it :

[tex]4x + 2y = 98[/tex]

[tex]2(2x + y) = 98[/tex]

[tex]2x + y = 49 - - - (1)[/tex]

[tex]x + y = 35 - - - (2)[/tex]

[tex](1) - (2)[/tex]

[tex]2x + y - x - y = 49 - 35[/tex]

[tex]x = 14[/tex]

[tex]substitute \: x = 14 \: into \: (2)[/tex]

[tex]14 + y = 35[/tex]

[tex]y = 35 - 14[/tex]

[tex]y = 21[/tex]

Answer:

[tex]\frac{9}{12}[/tex] is the biggest

Step-by-step explanation:

I converted the fraction to a decimal by dividing the numerator by the denominator.

[tex]\frac{6}{9}[/tex] is 0.6... (6 is repeating)

[tex]\frac{9}{12}[/tex] is 0.75

When looking at these 2 decimals I know 0.75 is bigger.

The equation y =0.7x represents the distance Henry hikes in miles over time in hours. The graph
represents the rate that Cark hikes. Determine which hiker is faster. Complete the explanation


Henry’s unit rate is ___ miles per hour. Clark’s unit rate is 1.5 miles per hour . So, ____ is faster.

Answers

Answer:

Henry’s unit rate is 0.7 miles per hour. Clark’s unit rate is 1.5 miles per hour . So, Ckark is faster.

Step-by-step explanation:

Distance covered by Henry is represented by y = 0.7x, where x = time (hrs), and y = distance (miles).

Distance covered in 1 hour by Henry would be:

y = 0.7(1) = 0.7 miles per hour

Distance covered by Clark in 1 hour = 1.5 miles per hour

Ckark covers more miles per hour than Henry covers in one hour, therefore, Ckark is faster.

Which of these equations, when solved, gives a different value of x than the other three?
9.1 = -0.2x + 10
10 = 9.1 + 0.2x
10 – 0.2x = 9.1
9.1 – 10 = 0.2x

Answers

Answer:

D. 9.1 – 10 = 0.2x

Step-by-step explanation:

I got it right

The odd equation with a different value is equation d

Data;

9.1 = -0.2x + 1010 = 9.1 + 0.2x10 - 0.2x = 9.19.1 - 10 = 0.2x

Linear Equation

To solve this problem, we have to solve each of the linear equations and get the value of x.

a)

[tex]9.1 = -0.2x + 10\\10 - 9.1 = 0.2x\\0.9 = 0.2x\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5[/tex]

b)

[tex]10 = 9.1 + 0.2x\\0.2x = 10 - 9.1\\0.2x = 0.9\\\frac{0.2x}{0.2} = \frac{0.9}{0.2} \\x = 4.5\\[/tex]

c)

[tex]10 - 0.2x = 9.1\\-0.2x = 9.1 - 10\\-0.2x = -0.9\\x = 4.5[/tex]

d)

[tex]9.1 - 10 = 0.2x\\0.2x = -0.9\\x = -4.5[/tex]

The odd equation with a different value is equation d

lisa an experienced shipping​ clerk, can fill a certain order in 7 hours. ​bill, a new​ clerk, needs
8 hours to do the same job. Working​ together, how long will it take them to fill the​ order?

Answers

Answer:

3.73 hours

Explanation:

In 1 hour, Lisa does 1/7th of the order while Bill does 1/8th of the order in an hour. To find out how long it will take them to fill the order, we have to:

Step 1:

Add the rate of both Lisa and Bill together

1/7 + 1/8

Step 2:

Since both denominators of the fractions are different, you have to find the least common multiple of 7 and 8

7·8= 56    8·7= 56

which is 56.

Step 3:

Then, you have to multiply the numerator of 1/7 with 8 and the numerator of 1/8 with 7.

1·8= 8    1·7= 7

The fractions would now have equal denominators:

Lisa: 8/56    Bill: 7/56

Step 4:

Now, you can add them together

8/56 + 7/56

which equals to 15/56. Both Lisa and Bill together completes 15/56th of the order in 1 hour.

Step 5:

15/56 is not the final answer as it is the RATE of them working together. To find how long it will take them total to complete the order, you must divide 56 with 15.

56/15

which is 3.73 hours in decimal form (rounded).

It should be A. 4, I think

A unit rate of 4 deliveries per hour.

What is the rate?

Rate is the special ratio in which two different terms are in different units.  a number, amount, or degree measured in relation to another object. a payment or charge that is calculated depending on another sum. more specifically: the premium per insurance unit. transitive verb rate.

Given that 16 deliveries are done in 4 hours. from that we can drive no. of deliveries in one hour. let's assume deliveries in one hour is x

For, x per hour =  16/4

x per hour is 4

Therefore the appropriate value for the unit rate of 4 deliveries per hour.
