Answer: 25

Step-by-step explanation:     (x-a)² = x² - 2ax + a²

  From x² - 10x + k  we deduce that 10x = 2·5x  and a = 5

Then k = 5²2

Answer:

40.

Step-by-step explanation:

10x4=40, those are the only factors in the equation and s will be 40.

Answer:

Equation: s-4=10

s=14

Step-by-step explanation:

It’s simple enough and I promise... I’m not fake! ;)

P(a) x p(b) = 2/5 x 1/4 = 2/20 = 1/10

1/10 does not equal 1/9 so the event is dependent

The answer is B ( the second choice)

Answer:

−9x+19

Step-by-step explanation:

Answer: −9x+25−3x^2

Step-by-step explanation:

1) Simplify  22-4x+122−4x+1  to  -4x+23−4x+23.

−4x+23−(3x 2+5x−2)

2) Remove parentheses.

−4x+23−3x^2−5x+2

3) Collect like terms.

(−4x−5x)+(23+2)−3x^2

4) Simplify

Answer:

$8

Step-by-step explanation:

We are told in the above question:

Mia hired a moving company. The company charged $50l for services, and Mia gives the movers 16% tip

The amount of money that Mia tips the movers is calculated as:

16% of $50

16% × $50

16/100 × $50

= $8

Therefore, Mia tips the movers $8

Answer:

B has a smaller initial population of 500

Step-by-step explanation:

Given

See attachment for complete question

Required

The bacteria with the smaller initial population

The initial population is at x = 0

For bacteria A;

[tex]A(x) = 600[/tex] when [tex]x = 0[/tex]

For bacteria B, we have:

[tex]B(x) = 500(2)^x[/tex]

Substitute 0 for x

[tex]B(x) = 500(2)^0[/tex]

[tex]B(x) = 500*1[/tex]

[tex]B(x) = 500[/tex]

So; when x = 0

[tex]A(x) = 600[/tex] and [tex]B(x) = 500[/tex]

Because; 500 < 600

We can conclude that B has a smaller initial population of 500

Here,

x + 118 = 180. [Since Supplementary Angle]

=> x = 180 - 118

=> x = 62 (Ans)

Step-by-step explanation:

Answer:

H was (Hx,Hy) goes to (Hy,-Hx)

G was (Gx,Gy) goes to (Gy,-Gx)

I was (Ix,Iy) goes to (Iy,-Ix)

Step-by-step explanation:

Rotating about the (0,0), the distance from any point to the origin (the hypotenuse of the triangle formed) never changes. A 90 clockwise rotation moves the point to the next quadrant, so side a and side b must flip to maintain the distance. You just need to flip the coordinates and change the sign of the new Y. If you plot a few random points and use a compass to rotate them 90 I think you will find this works.

Answer:

cos32= x/7

Step-by-step explanation:

When you are looking at the picture, you can see that we are given the adjacent and hypotenuse of this triangle. These are the components of cosine which is adjacent/hypotenuse. Set up the equation and you get cos32=x/7

Answer:

25>x-5 = x anything less than 30

Step-by-step explanation:

first add 5 to both sides

then u get 30.

30-5 is 25

so, you know that x must be any number less than 30 that is not 0

Answer:

x < 30

Step-by-step explanation:

[tex]25>x-5\\\\25+5>x-5+5\\\\{30>x}\\\\\boxed{x<30}[/tex]

Answer:

The volume of the first prism on the left is 504 cubic inches.

The volume of the second prims is 20 cubic inches.

Step-by-step explanation:

First prism:

Width: 9

Height: 8

9 * 8 = 72

72 * 7 = 504

---------------------------

Second prism:

Width: 8

Height: 4

8 * 4 = 32

32 * 5 = 160

Actually Welcome to the concept of Angles sum property.

Since the total angle is 90° , hence we get the equation as,

==> 33° + 6x + 3° = 90°

==> 36° + 6x = 90°

==> 6x = 90 - 36

==> 6x = 54°

hence, x = 54/6 = 9°

so, we get as,

==> 6x+3 ==> 6(9)+3 = 54+3 ==> 57°

Answer:

The answer to your question is --- 6x+3 --- 6(9)+3 + 54+3 --- 57°

Step-by-step explanation:

33° + 6x + 3° = 90°

36° + 6x = 90°

6x = 90 - 36

6x = 54°

x = 54/6 = 9°

I hope this helps and have a wonderful day!

The question is incomplete:

The dot plot shows the number of hours Stan worked each week for the last 3 months.

What fraction of the total number of weeks did Stan work 15 or more hours? Express in simplest form.

A. 5/7

B. 1/6

C. 1/5

D. 5/12​

The image with the dot plot is attached.

Answer:

D. 5/12​

Step-by-step explanation:

The dot plot shows the number of hours Stan worked and in order to know the number of weeks that he worked 15 hours or more, you have to count the dots that are between 15 and 18 hours. So, you have 3 dots in 15 hours, 1 dot in 16 hours and 1 dot in 18 hours. If you add this numbers (3+1+1=5), this means that he worked 5 weeks 15 or more hours. This number would be the numerator in your fraction. Then, the denominator would be the total amount of weeks and to find that you can count all the dots. The total number of dots is 12.

So, the fraction that represents the total number of weeks that Stan worked 15 or more hours is: 5/12. This is the simplest form because this numbers don't have any common factors other than 1.
