Answer:

4.5×10¹¹

Answer:

[tex](5 \times 10 {}^{3} ) \times (9 \times 10 {}^{7} )[/tex]

i) use the commutative property to rearrange the terms: a+b = b+a

[tex](5 \times 9) \times (10 {}^{3} \times {10}^{7} )[/tex]

ii) multiply the number in the 1st bracket

[tex]45 \times ( {10}^{3} \times 10 {}^{7} )[/tex]

iii) multiply the 2nd bracket by adding their exponents

[tex]45 \times 10 {}^{3 + 7} [/tex]

[tex]45 \times 10 {}^{10} [/tex]

iv) write the answer in standard form

[tex]4.5 \times 10 {}^{10 + 1} [/tex]

[tex]4.5 \times {10}^{11} [/tex]

The given equation that should be in the standard form should be like a [tex]4.5\times 10^{11}[/tex].

Since

The equation is [tex](5\times 10^3) \times (9\times 10^7)[/tex]

Now here we use the commutative property

So,

[tex]45 \times (10^3 \times 10^7)\\\\45 \times 10^{10}\\\\4.5 \times 10^{11}[/tex]

Here, we multiply the number in the 1st bracket, then add, it and then finally in standard form.

Answer:

12.5

Step-by-step explanation:

If an isosceles right triangle as the length of the equal sides is  a , then the length of the hypotenuse will be  a2–√  (using pythogoras theorem.

Hence the perimeter will be  a+a+a2–√=a(2+2–√)  

Hence the equal sides of the triangle in question has the length of  a=5  

Area of the triangle  =  12∗Height∗Base  

=12∗5∗5=12.5

Answer

6/-11

Step-by-step explanation:

use the slope formula m= [tex]\frac{y 2-y 1}{x 2-x 1}[/tex]

then sub in numbers m=[tex]\frac{7-1}{-5-1}[/tex]

now subtract numerator and the denominator

[tex]7-1= 6[/tex]    and

[tex]-5-6=-11[/tex]  this now looks like  [tex]\frac{6}{-11}[/tex]    

Answer:

Total = 800 books

Step-by-step explanation:

It is given that,

In a library, there are 3 non-fiction books for every 7 fiction books. It means that the ratio of non-fiction books to the fiction books is 3:7.

There if the library has 240 non-fiction books.

Let non fiction books are 3x and fiction books are 7x.

ATQ,

3x=240

x=80

Fiction books = 7x = 7(80) = 560

Total no of books = fiction books + non-fiction books

= 240 + 560

=800

Hence, the total no of books are 800.

Answer:

0.56%

Step-by-step explanation:

Percentage error

[tex] = \frac{2500 - 2486}{2500} \times 100 \\ \\ = \frac{1400}{2500} \\ \\ = 0.56\%[/tex]

The crowd at a sporting event is estimated to be 2,500 people, the exact attendance is 2,486 people, the percentage error is, 0.56%

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

The crowd estimated to be 2,500 people

The exact attendance is 2,486 people

Percentage error = ?

Percentage error = (estimated value- exact value)/estimated value×100

Percentage error =   (2,500 - 2,486) /2500×100

                             =  0.56%

So, the percentage error is 0.56%

Answer:

x is 6 i believeee if you're solving for x!!

Step-by-step explanation:

Answer:

x = 1 + 0.5 * 10^7

Step-by-step explanation:

Use log(a) + log(b) = log(ab).

log(x-1) + log(2) = 7 <=> log(2(x-1)) = 7 <=> log(2x-2) = 7

Using log(a) = b <=> a = 10^b

log(2x-2) = 7 <=> 2x-2 = 10^7 <=> 2x = 2 + 10^7 <=> x = 1 + 0.5 * 10^7

Given:

The expression is

[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)[/tex]

To find:

The index form of given expression.

Solution:

Index form is the exponent form, it means, the number is represented in power of a number.

We have,

[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)[/tex]

Here, we have 6 times -4. So, we get -4 as base and 6 as index or exponent.

[tex](-4)\times (-4)\times (-4)\times (-4)\times (-4)\times (-4)=(-4)^6[/tex]

Therefore, the index form of given expression is [tex](-4)^6[/tex].

Answer:

Option (E)

Step-by-step explanation:

[tex]\frac{a}{b}=\frac{c}{d}=k[/tex]

[tex]\frac{a}{b}=k[/tex]

[tex]b=\frac{a}{k}[/tex] ------(1)

[tex]\frac{c}{d}=k[/tex]

[tex]d=\frac{c}{k}[/tex] -------(2)

Since, [tex]\frac{6a+24}{md+6b}=k[/tex]

By substituting the values of b and d from equation (1) and (2),

[tex]\frac{6a+24}{\frac{mc}{k}+\frac{6a}{k}}=k[/tex]

[tex]\frac{k(6a+24)}{6a+mc}=k[/tex]

[tex]\frac{6a+24}{6a+mc}=1[/tex]

6a + 24 = 6a + mc

mc = 24

m = [tex]\frac{24}{c}[/tex]

Therefore, Option (E) will be the correct option.

The relation is not a function.

Relations that are functions will pass the vertical line test

The points are given as:

(0,0), (2,0), (2,2), and (3,4)

Next, we plot the points on the graph (see attachment).

From the graph, we can see that a vertical line passes through points (2,0) and (2,2).

Hence, the relation is not a function.
