The tree is 79 feet tall if the ground is 79 feet from the tree and the angle of elevation is 45°.

Angle of elevation:

The angle of elevation is an angle that is formed between the horizontal line and the line of sight.

Therefore, the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.

Given,

The angle of elevation to a nearby tree from a point on the ground is measured to be 45 degrees.

Here we need to find how tall is the tree if the point on the ground is 79 feet from the tree and we have also need to round the  answer to the nearest hundredth of a foot.

Here we know that

The angle of elevation = 45°

Distance of the point from the tree = 79 feet

Suppose h is the height of the tree.

Then the value of h is calculated as,

=> h / 79 = tan 45°

We know that, the value of tan 45° = 1,

So,

=> h/79 = 1

Then  the value of h is,

=> h = 79

Thus, the height of the tree is 79 feet.

Answer: This is the graph

a) By definition of standard form, a light-year is equal to 5.880 × 10¹² miles.

b) By simple rule of three, a magnitude of 4.25 light-year is equivalent to a magnitude of 2.499 × 10¹³ miles.

In this problem we need to convert a magnitude in miles to an equivalent magnitude in light-years and another magnitud in light-years to an equivalent magnitude in miles. Standard form is a notation used to represent both large and small number with no significant loss of precision. This form is described by the following form:

a.b × 10ⁿ

Where:

a) A light-year is equal to 5.880 × 10¹² miles.

b) The equivalent magnitude in miles is found by the following simple rule of three:

x = 4.25 ly × (5.880 × 10¹² mi / ly)

x = 2.499 × 10¹³ mi

A magnitude of 4.25 light-year is equivalent to a magnitude of 2.499 × 10¹³ miles.

On multiplying by [3], the slope becomes 3 times the original slope and

y - intercept becomes 3 times of the original value.

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

We have the following problem -

f(x) = ax + b, where [a] and [b] are nonzero real numbers. Now, the function f(x) is multiplied by 3.

The given straight line is -

y = f(x) = ax + b

After multiplied by [3], we get -

y' = 3f(x) = 3(ax + b) = (3a)x + (3b)

Therefore, on multiplying by [3], the slope becomes 3 times the original slope and y - intercept becomes 3 times of the original value.

Answer:

B

Step-by-step explanation:

To find the number of extra flowers ordered, we can start by forming an equation based on the total amount paid by the customer.

Let the number of extra flowers be n.

Total paid

= cost of standard arrangement +(number of extra flowers)(cost per additional flower)

= $25 +n($1.25)

Given that the customer paid $45,

25 +1.25n= 45

Now that we have formed the equation, let's solve for n.

Subtract both sides by 25:

1.25n= 45 -25

1.25n= 20

Divide both sides by 1.25:

n= 20 ÷1.25

n= 16

That indicates that in order to make a solution that is 60% acid, you will need to add a total of 300 milliliters of pure acid into the mixture.

This is further explained below.

In general, pure acid refers to an acid concentration of 100%. It is feasible to formulate the following equation if you assume that X represents the volume addition of the pure acid:

[tex]Va=100 \%X + 600 * 40 \%[/tex]

[tex]Va= (600+X)60 \% (M_1V_1=M_1 V_2)[/tex]

100X + 24000 = 36000 + 60x

X = 300.

Answer: 0.93

There are 9 tenths

Step-by-step explanation:

IF AB=3x, BC=x+5 and AC=24 then the midpoint of AC is point B.

Midpoint, as the word suggests, means the point which lies in the middle of something. Midpoint of a line segment means a point which lies in the mid of the given line segment.

WE have given that AB=3x, BC=x+5 and AC=24. Since B is the midpoint, then we have:

AB = BC = AC/2

Now Substitute and solve for x:

AB = BC

x + 5 = 3x

x + -3x = -5

2x = 5

x = 5/2

AB = 3(5/2) = 15/2

BC = x + 5 = 5/2 + 5 = 15/2

Hence, the midpoint of AC is point B.

By taking some products between fractions and mixed numbers, we will see that your trip along the bank has a length of (2 and 9/24) miles.

Here we know that the total distance of the travel is (14 + 1/4) miles.

In this case, we know that 1/3 of that distance is traveled in the woods, so the total distance traveled in the woods is given by the product:

D = (1/3)* (14 + 1/4) mi = (14/3 + 1/12) mi

Now we know that 1/2 of the distance traveled in the woods is traveled along the bank of a strem, then the distance that we are looking for is given by the product:

D' = (1/2)*(14/3 + 1/12) mi = (7/3 + 1/24)mi

Now we can simplify that mixed number as:

(7/3 + 1/24)mi = (6/3 + 1/3 + 1/24) mi = (2 + 8/24 + 1/24)mi = (2 + 9/24) mi
