what is the range of possible sizes for x?

Answers

Answer:

0.5 < x < 15.5

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

The two side lengths given in the triangle of the figure are y=8.5, z=8.0, thus the possible values of x lie in the interval

8.5 - 8.0 < x < 8.5 + 8.0

0.5 < x < 15.5

How much must be added to each of the three number 1, 11, and 23 so that together they form a geometric progression?

Answers

Answer:

49

Step-by-step explanation:

Let the three numbers be a1, a2, a3

Let the number to be added to form a geometric progression = x

a1 = 1 + x ; a2 = 11 + x ; a3 = 23 + x

For a geometric progression :

a2 = a1 * r

a2 = (1+x)r

11+x = (1+x)r - - (1)

r = (11+x) / (1+x) ---(1)

a3 = a2 * r

a3 = (11+x)r

23+x = (11+x)r - - -

r = (23+x) / (11+x) - - (2)

Equate (1) and (2)

(11+x) / (1+x) = (23+x) / (11+x)

(11+x) * (11+x) = (23+x) * (1+x)

121 + 22x + x² = 23 + 24x + x²

121 + 22x + x² - x² - 24x - 23 = 0

98 - 2x = 0

-2x = - 98

x = 98 / 2

x = 49

PLEASE HELP ME OLEASE UT URGENT !

Answers

Answer:

Explanation:

m = (y1 - y)/(x1 - x)

y1 = 50, y = 90
x1 = 2, x = 4

m = (50 - 90)/(2 - 4)
m = -40/-2
m = 20

b is the y intercept = 50

So our equation is written as:

y = 20x + 50

Solve the equation: 1/2(4x - 16) = 14
what is x
x = 11

x = 3.75

x = -2

x = 5

Answers

Answer:

        x = 11

Step-by-step explanation:

1/2(4x - 16) = 14

2x - 8 = 14             {add 8 to both sides}

 2x = 22               {divide both sides by 2}

   x = 11

When building a house, the number of days required to build is inversely proportional to with the number of workers. One house was built in 147 days by 4 workers. How many days would it take to build a similar house with 42 workers?

Answers

Answer:

14

Step-by-step explanation:

[tex]147 \times 4 \div 42 = 14[/tex]

It would take 14 days  to build a similar house with 42 workers

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that  the number of days required to build is inversely proportional to with the number of workers.

One house was built in 147 days by 4 workers.

So,

147 x 4 = 588

Now the days to build a similar house with 42 workers

588/ 42 = 14

Answer:

You multiply the number outside the parentheses by each one I side the parentheses. Following the distributive property, you have to "distribute" the multiplication, so each number/variable gets multiplied by the first number.

Reasoning Explain why either a or b must be 0 if ab = 0, but neither a nor b
must be 4 when ab = 4.

Answers

By the zero product property, a or b must be 0 if ab = 0. Or you could solve for each variable.

Divide both sides by b:
b=0/a —> b=0

Divide both sides by b:
a=0/b —> a=0

Hmm A could be 4 and b could be 1 because 4*1=4
