Ruth decides to test the method of proportions and similar
triangles to find the height of a tree. She decides to again find the
height of a tree she had measured earlier in the day at 10 A.M. This
time, she decides to use this method at 5 P.M. in the evening. She
measures the length of the tree's shadow and finds it to be 48 feet
long this time. Then she holds a 12-inch ruler perpendicular to the
ground and finds that it casts a 24-inch shadow. How tall will she find
the tree?

here is an inequality: 2x+5>50. explain the steps you would use to solve the inequality for x. what would the graph look like

Answers

Answer:

Step-by-step explanation: 2 plus 5

7 <50

Answer:

x = 22.5

Step-by-step explanation:

2x + 5 > 50.

We do inverse operations sooo:

2x + 5 - 5 > 50 - 5.

50 - 5 = 45.

Then we do 2x ÷ 2 and 45 ÷ 2.

45 ÷ 2 = 22.5.

To check our answer to see if its right we do 22.5 x 2 which equals 45. Then we do 45 + 5 which equals 50. So the sign is wrong it should be greater than or equal to.

The length of a path from a picnic area to the playground is 34 mile. The path has signs with arrows pointing to the playground every 18 mile.

How many signs are placed along the path, assuming that there is a sign at the beginning of the path but not at the end?

Answers

If there is one at the beginning we have one. At the 18 mile we will have a second sign. There should only be two signs because 18 plus 18 is 36, meaning there wouldn’t be room for another. Hope this helped!

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Length of the path = 34 mile

There is a sign after every 18 miles.

Now,

There is a sign at the beginning of the path and not at the end.

The number of signs:

= 34 ÷ 18

= 34/18
= 1.8

This means there will be one sign.

Now,

There was a sign at the beginning so we have,

1 + 1 = 2 signs

Thus,

The number of signs that are placed along the path, assuming that there is a sign at the beginning of the path but not at the end is 2 signs.

i need help on the last part!

Answers

Answer:

0; (0, 0); 144; (3, 144)

Step-by-step explanation:

Y = distance (m)

X = time (hr)

X = 48x

If a car travels for 0 hours, it will travel __ mile(s).

y = 48x

Plug in 0 hours for x (time in hours)

y = 48(0)

Any number mutliplied by 0 equals 0

y = 0

If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).

(0, 0) limits our options to graphs B and D

Car travels 144 miles in 3 hours

To find how many miles it travels in 1 hour, divide 144 miles by 3 hours

144 ÷ 3 = 48

In 1 hour, a car travels 48 miles

If 48 × 3 = 144, then 48 × 4 = ?

48 × 4 = 192

When looking at graph D, there are 4 lines above 0

Counting by 48, it perfectly fits 192 by the fourth line

From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting

Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144

Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship

Density is measured in units of mass per units of volume. It can be thought of as a unit rate. The mass of a block of aluminum is 9.45 grams. The volume is 3.5 cubic centimeters (cm³).

What is the density of aluminum?

Answers

Answer:

you answer will be 2.7

Step-by-step explanation:

you just have to divide the 9.45 to 3.5 and you got your answer

The density of the aluminum will be 2700 kilograms per cubic meter.

What is the density?

The number of molecules per unit volume is known as density. The SI unit of the density is kilograms per meter cube. The density is a scalar quantity. More density means more the number of molecules present in a unit volume. Then the density is given as,

Density = Mass / Volume

A chunk of metal weighs 9.45 grams. 3.5 cubic centimeters is the volume.

Then the density of the aluminum is given as,

D = 9.45 / 3.5

D = 2.7 grams per cubic cm

D = 2700 kilograms per cubic meter

The density of the aluminum will be 2700 kilograms per cubic meter.
