Mike wrote down a number on a piece of paper and hid it from his friends. He rounded his number to different places and his friends had to guess what the number was.

First, Mike rounded his number to the nearest ten.
Then, he rounded his number to the nearest hundred.
Last, he rounded his number to the nearest thousand.
All three times, the rounded number had the same value.
Which of these could be his number?

145,998
7,002
4,506
26,991
12,497

Percentage - In mathematics, a percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%"

we can substitute 40% for 0.4x and make an equation

[tex]x-0.4=90[/tex]

simplify

[tex]0.6x=90[/tex]

divide both sides by 0.6

[tex]x=150[/tex]

Answer:

SHINE

Step-by-step explanation:

remember : the slope (the factor of x in the equations) is the ratio "y coordinate change / x coordinate change".

and the constant at the end of the equations are the y-intercept (the y value for x = 0).

Step-by-step explanation:

Answer:

m∠PBQ=51

Step-by-step explanation:

By vertical angles theorem, ∠PBQ ≅ ∠LBM, so m∠PBQ=m∠LBM.

And since ∠LBM & ∠LBQ are supplementary, we'll write,

m∠LBM+LBQ=180°

3x+(4x+61)=180°

Let's solve for x:

7x=119

7x/7=119/7

x=17

So...

m∠LBM=3(17)

m∠LBM=51

This means that m∠PBQ=51

Answer:   39.25

========================================

Work Shown:

d = diameter = 10

r = radius = d/2 = 10/2 = 5

A = area of a full circle

A = pi*r^2 = 3.14*5^2 = 78.5

Cut this in half to get the area of a semicircle (aka half circle)

(78.5)/2 = 39.25

This result is approximate.

Answer:

Step-by-step explanation:

We have to simplify this equation.

Answer:

y = 12x+3

Step-by-step explanation:

y = mx+c

m is the gradient/slope

c is the y intercept

so m is 12 and c is 3

Answer:

Use the definition of a logarithm,

log b(x)= y ⟹  b^y = x, to convert from the logarithmic form to the exponential form. 10^5 = 4

Step-by-step explanation:

The exponential form of the given logarithmic equation is [tex](9x+7)=4^5[/tex].

Important information:

The given equation can be written as:

[tex]4^{\log_4(9x+7)}=4^5[/tex]

[tex](9x+7)=4^5[/tex]               [tex][\because a^{\log_ab}=b][/tex]

Therefore, the exponential form of the given logarithmic equation is [tex](9x+7)=4^5[/tex].

The table which  represents a quadratic relationship is in option [tex]D[/tex].

A quadratic relationship is a mathematical relation between two variables that follows the form of a quadratic equation.

Quadratic sequence [tex]=an^2 +bn+c[/tex]

So, According to the definition mentioned above if table follows the  form of a quadratic equation then it is in quadratic relationship.

So,

To find out quadratic relationship,

We will find first difference in every table and then second difference (Second difference is the difference between the first difference).

We have,

Table A;

[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &4&2-4=-2\\-1& &2&1-2=-1&-1+2=1\\0& \ &1&0.5-1=-0.5&-0.5+1=0.5\\1& &0.5&0.25-0.5=-0.25&-0.25+0.5=0.25\\2& &0.25&0.125-0.25=-0.125\\3& &0.125\end{array}\right[/tex]

So, In the above table we can see that second difference  is not equal that means it is not in quadratic relationship.

Now,

Let Table D;

[tex]\left \begin{array}{ccccc}x& \ &f(x)&First\ Difference & Second\ Difference \\-2& &-23.4&\\-1& &-23.2&-23.2+23.4=-0.2&0.2-0.2=0\\0& \ &-23&-23+23.2=-0.2&0.2-0.2=0\\1& &-22.8&-22.8+23=-0.2&0.2-0.2=0\\2& &-22.6&-22.6+22.8=-0.2\\3& &-22.4&-22.4+22.6=-0.2\end{array}\right[/tex]

So, here in this table, we can see that second difference  is equal that means it is in quadratic relationship.

Hence, we can say that the table which  represents a quadratic relationship is in option [tex]D[/tex].

Answer:

  (d)  yes; -7

Step-by-step explanation:

The differences between terms are ...

  12 -19 = -7

  5 -12 = -7

  -2 -5 = -7

These are all the same, so this difference is "common". A sequence in which terms have a common difference is an arithmetic sequence.

This sequence is arithmetic, with a common difference of -7.

The answer is 28 or 504. My explanation....

ALRIGHT! So, it took me a little while to do it all.... since I wasn't really sure if it was already multiplied by 18 or not.

So the normal numbers in order from least to greatest,(because that's easier)

14, 18, 20, 28, 36, 58, 71.

The new numbers I multiplied by 18 are...

252, 324, 360, 504, 648, 1044, 1268.

When I put it like that you can clearly see the new median. 28 and 504!
