Cari owns a horse farm and a horse trailer that can transport up to 8,000 pounds of livestock and tack. She travels with 5 horse

const2013 [10]

Answer:

5(1248 lb/horse + t lb) ≤ 8000 lb

Step-by-step explanation:

One way to do this is to find the average weight of the 5 horses:

It is:

6,240 lb

---------------- = 1248 lb/horse

5 horses

and to this, for each horse, we must add t lbs tack.

Thus, 5(1248 lb/horse + t lb) ≤ 8000 lb

would be an appropriate inequality.

Please note that your question mentions "the following inequalities;" that means you are expected to share them! Please do so next time. Thanks.

Rachel runs 6 miles in 50 minutes. At the same rate, how many miles would she run in 35 minutes?

Naily [24]

Answer: 4.2 miles

Step-by-step explanation:

So she ran 6 miles in 50 minutes how long will she run in 35 minutes?

So the equation will therefore be:

6=50

x=35

Cross multiply

6 x 35 = 50x

210 = 50x

Divide both sides by 50

The answer is 4.2 miles

Tommy is using a bucket to collect nuts from a nut tree. He then dumps the bucket into a barrel for shipping of the nuts. He not

NISA [10]

Answer:

3/8 bucket

Step-by-step explanation:

Given that 1/4 bucket of nuts fills 2/3 of the barrel

PART A

To find the amount of nuts that fills entire basket we can put this as:

1/4 bucket → 2/3 barrel
x bucket → 1 barrel

Use cross-multiplication to find the value of x:

x×2/3 = 1×1/4
x = 1/4 ÷ 2/3
x = 1/4×3/2
x = 3/8 bucket

PART B

Using the bucket to barrel ratio to solve the problem. Having the number of required buckets as x and considering full barrel as 1 helps to find the value of x.

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

A is final amount
P is principle (initial) amount
r is rate
t is time (in years)

Step-by-step explanation:

Step 1: Define

P = 7200

r = 0.75% = 0.0075

t = 5

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7200(1 + 0.0075)^5$
(Parenthesis) Add: $\displaystyle A = 7200(1.0075)^5$
Evaluate exponents: $\displaystyle A = 7200(1.03807)$
Multiply: $\displaystyle A = 7474.08$
