On a recent trip to a local orchard, the Morgan family picked four different kinds of apples - Braeburn, Cortland, Fuji, and Rom

ivanzaharov [21]

Answer:

Morgan family picked 144 Braeburn apples, 96 Cortland apples, 72 Fuji apples and 48 Rome apples.

Step-by-step explanation:

Let B, C, F and R represent Braeburn apples, Cortland apples, Fuji apples, and Rome apples respectively.

We have been given that Morgan family picked a total of 360 apples. We can represent this information in an equation as:

$B+C+F+R=360...(1)$

We are told that Morgan family picked twice as many Braeburn as Fuji. We can represent this information in an equation as:

$B=2F...(2)$

We are told that Morgan family picked twice as many Cortland as Rome, that is:

$C=2R...(3)$

We are told that Morgan family picked 50% more Fuji than Rome, that is:

$F=1.5R...(4)$

Upon substituting equation (4) in equation (2), we will get:

$B=2(1.5)R$

$B=3R$

Now, each apple in in terms of Rome apples, so we will get:

$3R+2R+1.5R+R=360$

Let us solve for R.

$7.5R=360$

$\frac{7.5R}{7.5}=\frac{360}{7.5}$

$R=48$

Therefore, Morgan family picked 48 Rome apples.

Upon substituting $R=48$ in (3), we will get:

$C=2R\Rightarrow 2(48)=96$

Therefore, Morgan family picked 96 Cortland apples.

Upon substituting $R=48$ in (4), we will get:

$F=1.5R\Rightarrow 1.5(48)=72$

Therefore, Morgan family picked 72 Fuji apples.

Upon substituting $F=72$ in (2), we will get:

$B=2F\Rightarrow 2(72)=144$

Therefore, Morgan family picked 144 Braeburn apples.

7/10 divide by 1/5 - 4/3 x 10/11

Karolina [17]

Answer:

(-340)/231

Step-by-step explanation:

Simplify the following:

((-34)/33)/(7/10)

Multiply the numerator by the reciprocal of the denominator, ((-34)/33)/(7/10) = (-34)/33×10/7:

(-34×10)/(33×7)

33×7 = 231:

(-34×10)/231

-34×10 = -340:

Answer: (-340)/231

The gestation period of horses (336 days)—- percent longer than the gestation period of cats (62 days). I need to find the perce

Mazyrski [523]

We have been asked to find percentage change of the gestation period of horses and cats.

First of all we will find difference between our two numbers.

$\text{Difference}=336-62=274$

Now we will find percentage of our difference with respect to gestation period of cats.

$\text{Percentage change}=\frac{274}{62} \cdot100$

$\text{Percentage change}=4.41935 \cdot100=441.935\appox442$

Therefore, gestation period of horses is 442% longer than the gestation period of cats.
