Answer:

Step-by-step explanation:

Here, b=8 and c=10, so,

a=b/2

=8/2

=4

and

b=c-a²

=10-16

Answers

Answer:

1. [tex]-5-\sqrt{x}[/tex]

2. [tex]7+\sqrt{b}[/tex]

Step-by-step explanation:

The conjugate of a radical expression

[tex]a+\sqrt{b}[/tex]

is the expression

[tex]a-\sqrt{b}[/tex]

And vice-versa.

The conjugate is mostly used to rationalize radical expressions because the expression by its conjugate produces another expression without the radicals.

The question asks to find the conjugate of:

1. [tex]-5+\sqrt{x}[/tex]

The conjugate is

[tex]-5-\sqrt{x}[/tex]

2. [tex]7-\sqrt{b}[/tex]

The conjugate is

[tex]7+\sqrt{b}[/tex]

Step-by-step explanation:

The Leaning Tower of Pisa in Italy was built between 1173 and 1350. A. Write an equation in slope-intercept form for the yellow line. Equation: y= b. The tower is 56 meters tall. How far off center is the top of the tower? The top of the tower is meters off center

Answers

Answer:

The answer is below

Step-by-step explanation:

From the image of the leaning tower of Pisa, we can see that it passes through the point (7.75, 0) and (10.75, 42).

a) The equation of a line in slope intercept form is given by y = mx + b, where m is the slope and b is the intercept. Also, the equation of line passing through

[tex](x_1,y_1)\ and\ (x_2,y_2)\ is:\\\\y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Hence since it passes through  (7.75, 0) and (10.75, 42), the equation is:

[tex]y-0=\frac{42-0}{10.75-7.75} (x-7.75)\\\\y=14(x-7.75)\\\\y=14x-108.5[/tex]

b) When the tower is 56 meters tall, i.e. y = 56, we need to find the value of x:

y = 14x - 108.5

56 = 14x - 108.5

56 + 108.5 = 14x

164.5=14x

x = 164.5/14

x = 11.75

When the tower is 56 meters tall, the top of the tower is 11.75 m off center

There are 19.3 cups of flour in a bag. The chef uses 2.9 cups for making cookies. Then, he uses 1.2 cups of sugar and 5.1 cups of flour for making banana bread. How many cups of flour are left?

Answers

Answer:

10.1

Step-by-step explanation:

19.3-2.9=16.4

16.4-1.2=15.2

15.2-5.1=10.1

so there are 10.1 cups of flower left

Answer:11.3

Step-by-step explanation:

19.3 - 2.9 -5.1= 11.3

You don't subtract the 1.2 cups of sugar because it's only asking about the flour.

A music store marks up the instruments it sells by 30%. If the price on a trumpet says $104. How much did the store pay for it?

Answers

Answer:

A. $ 58.50

B. $ 80

C. No, it did not mark up 30%

Step-by-step explanation:

Since,

A. We have,

Mark up percentage = 30%

Actual price = $ 45,

 B. We have,

SP = $ 104,

  C.  We have,

AP = $ 75,

SP = $100,

Thus, mark up percentage =  

= 33.33 %

Hence, store did not mark up the price by 30%.

Answer:

$ 72.80

Step-by-step explanation:

30% of 104 = 0.30 * 104

                  = $ 31.20

Money paid by the store = 104 - 31.20

                                         = $ 72.80

The value of  8/9/20 could be either 0.04 or 17.77.

What is a fraction?

In such a fraction, the value that appears above the horizontal line is referred to as the numerator.

In another word, the fraction is the division of the two numbers but the division is not wholly complete.

In another word, if we divide two numbers by each other then the upper word is called the numerator, and a lower word is called the denominator.

It represents the number of pieces removed from the whole. The denominator of a fraction is the numerical value that comes before the brings together various.

Given the fraction,8/9/20

Case 01)

(8/9)/20 = 0.888/20 = 0.044.

Case 02)

8/(9/20) = 8/0.45 = 17.77.

Hence "The value of  8/9/20 could be either 0.04 or 17.77".
