Answer:

(7x + 10y)

Step-by-step explanation:

To find this add (3x - 4y) to itself to calculate to lengths of the shorter sides.

(3x - 4y) + (3x - 4y) = 6x - 8y

Subtract this from (20x + 12y)

(20x + 12y) - (6x - 8y) = 14x + 20y Divide this by two to get the length of one side

14x + 20y / 2 = 7x + 10y

A farmer harvested some of his pecan crops on Friday and Saturday.what fraction of the pecan crop was harvested in two days

Sloan [31]

Answer:

Hence the 3.28 %or 2/61 of total work will be done .

Step-by-step explanation:

Given:

The pecan crops are harvested for friday and saturday (2days)

To find :

What fraction these 2 days corresponds to the harvesting days?

Solution;

The pecan crops are growing in America in state of Georgia

and consider that in months of October and November pecan crop becomes mature .

Hence the harvesting period is of 2 months considerably .

The month of October and November days are 31 and 30 .

Hence the Total days of harvesting are 61 days.

In these days total Pecan crops will be harvested.(100% work in 61 days)

Now the farmer harvest for 2 days only .

Required fraction=2/61

=0.0327869

=3.28%

Depending upon the crop field and planting answer will vary

But 3.28 % of total work will be done in 2 days on harvesting

Jenna's 4Runner is expected to get 22 miles/gallon on the highway, or she can

d1i1m1o1n [39]

Answer: A.4Runner cost more for $11.02

B.Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fuel for 4Runner : 6.818*3.59=$24.48

Step-by-step explanation:

A.Find how many gallons 4Runner spends on 150 mile trip.

use proportion

22:1=150:x

22x=150

x=150/22

x=6.818 gallons

Cost of fuel for 4Runner : 6.818*3.59=$24.48

Calculation for Elentra:

40:1=150:x

40x=150

x=150/40

x=3.75 gallons

Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fule for 4Runner-Cost of fuel for Elentra=24.48-13.46=$11.02

4Runner cost more for $11.02

B.Cost of fuel for Elentra: 3.75*3.59=$13.46

Cost of fuel for 4Runner : 6.818*3.59=$24.48

You roll a 6-sided die. What is P(prime)? Write your answer as a percentage. Submit

Cloud [144]

You roll a 6-sided die. The probability of getting prime is 50%.

Solution:

Given, that we have rolled a 6 – sided die.

We have to find the P(prime) as percentage.

Now, It means that we have to find the probability of getting a prime number on the face.

On rolling a six sided die, the total possible outcomes are 1, 2, 3, 4, 5, 6

Number of possible outcomes = 6

We have to get a prime number on rolling a die

The prime numbers in possible outcomes are 2, 3, 5

So number of favorable outcomes = 3

$\text {Probability of an event as percentage }=\frac{\text { favourable number of outcomes }}{\text { total number of outcomes }} \times 100$

$\text {Probability of getting prime number on face of die }=\frac{3}{6} \times 100$

$\begin{array}{l}{\text { P(prime) }=\frac{1}{2} \times 100} \\\\ {\text { P(prime) }=50 \%}\end{array}$

Hence, probability of getting prime is 50%.
