In sunlight, a vertical stick 6 ft tall casts a shadow 2 ft long. At the same time a nearby tree casts a shadow 14 ft long. How tall is the tree? Round to the nearest tenth.

In Sunlight, A Vertical Stick 6 Ft Tall Casts A Shadow 2 Ft Long. At The Same Time A Nearby Tree Casts

Answers

Answer 1

Answer:

42.0 ft

Step-by-step explanation:

let t be the height of the tree.

At the same time ,the measure of something

and its shadow are proportional .

Then

[tex]\frac{2}{6} =\frac{14}{t}[/tex]

Then

2t = 6 × 14

Then

2t = 84

Then

t = 84/2

Then

t = 42

Therefore the tree is 42 ft tall

One side of a triangle has length $10$, and the triangle has integer perimeter. What is the smallest possible perimeter of the triangle

Answers

The smallest possible perimeter of the triangle is 21.

The third important property of triangles is the triangle inequality rule, which states: that the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference between the lengths of the other two sides.

so let 10 = a  

10 < b+c        

So a good integer value for b+c   would be 11

10 >  b-c        

If we let b be the bigger of the two 10 and 1  would work for b and c respectively or 7 and 4 or 6 and 5 or 6.5  4.5, etc

A bike store marks up the wholesale cost of all bikes they sell by 30%. calvin wants to buy a bike that has a price log of 123.50. what was the wholesale cost of the bike?

Answers

The wholesale cost of the bike is 95.

Wholesale price is the price charged for a product as sold in bulk to large trade or distributor groups as opposed to what is charged to consumers.

The selling price is how much a buyer pays for a product or service.

The profit formula is used to calculate the amount of gain that has been made in a transaction

Profit = Selling Price (S.P.) - Cost Price (C.P.)(here it is the wholesale price)

Given =  

Selling Price = 123.50Wholesale price = ?Profit = 30% of wholesale price

Substituting it in the profit formula we get

0.3 x wholesale price = 123.50 + wholesale price

1.3 x wholesale price = 123.50

Wholesale price = [tex]\frac{123.50}{1.3}[/tex] = 95

Thus the wholesale cost of the bike is 95.

Step-by-step explanation:

Given functions:f(x) = 3x - 2g(x) = x + 1Solution:

Add both functions

(f+g)(x) = 3x - 2 + x + 1

Combine like terms

(f+g)(x) = 3x + x - 2 + 1

(f+g)(x) = 4x - 1

[tex]\rule[225]{225}{2}[/tex]

Answer:

[tex](f+g)(x)=4x-1[/tex]

Step-by-step explanation:

Functions

Functions written in equation form usually have several parts:

nameinputMathematical rule/expression that tells what the function does to the input to give an output.

So, for instance, [tex]g(x)=x+1[/tex] has a name of "g", has an input of "x", and has a rule that it adds 1 to the input to get the output.

The name of the function should tell what rule to follow (look for the equation with that function name), or it may give some details on what the function does.

Dealing with so many different problems, functions often get a default name of "f", "g", or "h".  

If a function is special and/or used commonly, it will sometimes get a special name (like the natural logarithm function "ln").

This function

In this case, the function is (f+g)(x).  The function name means that the result of each function, f and g, will be added together, while using the same input "x" for both functions.

[tex](f+g)(x)=f(x)+g(x)\\=(3x-2)+(x+1)\\=3x+(-2)+x+1\\=4x+(-1)\\=4x-1[/tex]

So, given these two functions for "f" and "g",  [tex](f+g)(x)=4x-1[/tex]

Answers

Answer:

C. Infinitely many

Step-by-step explanation:

First, find x.

3(x-2)=22-x

Use distributive property.

3x-6=22-x

Add x to both sides.

4x-6=22

Add 6 to both sides.

4x=28

Divide 4 from both sides.

x=7

Plug in 7 for x into the original equation.

3(7-2)=22-7

Answer:

x=11, y=2

Step-by-step explanation:

We can set 1 equal to x-5y and then solve for x. and y.

x = 5y+1

y = x-1/5

We can use this information and plug back in the values for 3y-x or x-5y.

We can set -3 = 3y-x or 1 = x-5y.

To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.

We can do a bit of algebra which would get us x = 11.

Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.

y=2
