A person who is 68in tall casts a shadow that is 54in long. At the same moment, a tree casts a shadow that is 18ft long. What is

34kurt

Answer:

22.67 ft is the height of tree.

Step-by-step explanation:

Given:

Height of a person is 68 in and casts a shadow that is 54 in long.

At the same point, a tree casts a shadow that is 18 ft long.

Now, to find the height of tree.

Let the height of tree be $x.$

If height of a person is 68 in he casts a shadow of 54 in.

So, 68 in is equivalent to 54 in.

Thus, $x$ is equivalent to 18 ft.

Now, to get the height of tree by using cross multiplication method:

$\frac{68}{54} =\frac{x}{18}$

By cross multiplying we get:

$1224=54x$

Dividing both sides by 54 we get:

$22.67=x$

$x=22.67\ ft.$

Therefore, the height of the tree is 22.67 ft.

A tile pattern has five tiles in Figure 0 and adds seven tiles in each new figure. Write a linear equation that represents this

Olenka [21]

The linear equation that represents the number of tiles in figure x is given by:

$y = 7x + 5$

---------------------

A linear equation has the format:

$y = mx + b$

In which:

m is the slope, that is, the rate of change.
b is the y-intercept, that is, the value of y when x = 0.

---------------------

Figure 0 has 5 tiles, that is, when $x = 0, y = 5$ , thus $b = 5$
Seven new tiles in each figure, that is, a rate of change of 7, thus $m = 7$

The number of tiles in figure x is given by:

$y = 7x + 5$

What is the solution to the system of equations below?

kifflom [539]

Answer:

(-5,-14)

Step-by-step explanation:

To find the solution of the system of two equations

$\left\{\begin{array}{l}y=4x+6\\y=2x-4\end{array}\right.$

equate right sides of these two equations:

$4x+6=2x-4$

Rewrite terms with x into the left side and without x into the right side:

$4x-2x=-4-6\\ \\2x=-10\ [\text{divide by 2}]\\ \\x=-5$

Substitute x=-5 into the first equation:

$y=4\cdot (-5)+6=-20+6=-14$

The solution is (-5,-14)

What is the equation of a line that has a slope of 0 and passes through (5, −2)?

kumpel [21]

y=-2

Step-by-step explanation:

if line has zero slope (b) it means that b is undefined.

if x=0 y=-2 because line has no slope. so b=-2

y=-2
