On Tuesday, Marissa was $45 short of her fundraising goal. The next day, she was $5 over her goal write an equation to show how

scoray [572]

Answer: Hello daema, let's let x be the goal and c be the collection per day.

x - 45 + c = x + 5 is the answer so now let's talk about how we did that.

So she wants to get to x which is the goal. But right now she has 45 less than what her goal is. So that would look like this x - 45 now she has to get c or the collection per day to get to her goal. So now it looks like this x - 45 + c. Now that c has to be at least x which is her goal, it now will look like this x - 45 + c = x. But we're not done, the question said that now she 5$ over her goal, or x. So we have to add the + 5 onto the end so now it looks like this x - 45 + c = x + 5. To solve the equation "if you have to" it would be x = 50$ per day.

Can someone help me with this problem:)

Answer:

Therefore,

93.6 feet tall is the tower from the ground.

Step-by-step explanation:

Given:

x = Opposite side to angle 60

50 ft = Adjacent side to angle 60

7 ft = height of boy

So Height of the tower will be,

$Height\ of\ tower=x+7$

To Find:

Height of the tower = ?

Solution:

In Right Angle Triangle , Tangent Identity we have,

$\tan 60= \dfrac{\textrm{side opposite to angle 60}}{\textrm{side adjacent to angle 60}}$

Substituting the values we get

$1.732= \dfrac{x}{50}\\\\x=86.6\ ft$

Substituting "x" For Height of tower we get

$Height\ of\ tower=86.6+7=93.6\ ft$

Therefore,

93.6 feet tall is the tower from the ground.

The U.S. has about 190 million acres of national forest. One square mile is the same as 640 acres. How many states the size of W

DochEvi [55]

Answer:

Around 3

Step-by-step explanation:

It is given that 1 sq. mile is equal to 640 acres.

<em>Let's convert 190 million acres to sq. miles.</em>

$190,000,000*\frac{1Sq.Mi.}{640Acres}=296,875Sq.Mi.$

<em>Taking Wyoming as a rectangle, we can find the area of Wyoming by multiplying length (352 miles) with width (278 miles).</em>

Area of Wyoming is $352*278=97,856$

To find the number of Whyoming's in total area of national forests, we divide the area of national forests (in sq. mi.) by the area of Wyoming ( in sq. mi.):

$\frac{296,875}{97,856}=3.03$

So, around 3 Wyoming states' area will cover the area of national forests in US.
