Together teammates pedro and ricky got 2685 base hits last season. Pedro had 277 more than ricky. How many hits did each player
Ksju [112]
Let x be the number of base hits Ricky got. With this representation, the number of base hits Pedro got is x + 277. The sum of their number of hits is equal to 2685. The equation that best represent the scenario is,
                                   x + x + 277 = 2685

90. The number of daily evening newspapers in the United States has decreased by 46.5% to
aleksandr82 [10.1K]

Answer:

700

Step-by-step explanation:

Given:

Daily evening newspapers in 2015 = 389

Percentage decrease from 2000 to 2015 = 46.5%

To find:

Number of newspapers in 2000 = ?

Solution:

Let the number of newspapers in 2000 = x

When 46.5% of the total newspapers in 2000 (x) is subtracted from the total  newspapers in 2000 (x), it will be equal to the number of newspapers in 2015.

Making the equation as per the given statement:

x-x\times 46.5\%=389\\\Rightarrow \dfrac{100x-46.5x}{100}=389\\\Rightarrow 53.5x=38900\\\Rightarrow x\approx \bold{727}

Therefore, the answer is:

There were <em>727 </em>newspapers in 2000.

Answer:

The length of the ramp must be at least 14.71 feet

Step-by-step explanation:

Given

BC = 2.3ft

\theta = 9^\circ

<em>See attachment for complete figure</em>

Required

Length of the ramp (z)

To do this, we consider sin of angle A (\theta).

So, we have:

sin\theta = \frac{Opposite}{Hypotenuse}

This gives:

sin(9)= \frac{2.3}{z}

Make z the subject

z= \frac{2.3}{sin(9)}

z = \frac{2.3}{0.1564}

z = 14.71 ft

<em>The length of the ramp must be at least 14.71 feet</em>
