5*2=10

Answer:

Step-by-step explanation:

(8 - 8i) + (1 + 6i)

8 + 1 - 8i + 6i

9 - 2i

A / b = c

Multiply both sides by b

A = bc

Divide both sides by c

A / c = b

Answer:

a)0.09176

b)0.22065

c)0.62551

Step-by-step explanation:

a) p(x>21) = p(z> (21-17)/3)=p(z>1.333) = 1-.90824= 0.09176 (subtracting from one because we are looking at the right side of the graph from the Z-table)

b)p(x<15) = p(z< (15-17)/3)=p(z<-.6667) = 0.22065

c)p(16 < x < 25)= (z(16-17)/3 < p < z(25-17)/3)= z(-.333) < p < z(2.667)=.99621 -.37070 = 0.62551

Answer:

9/10

Step-by-step explanation:

3/5 gallon paint = 2/3 of wall

if you divide 3/2 each side then...

9/10 gallon of paint = 1 wall

Answer:

1/5 of a wall

Step-by-step explanation:

if you take 3/5 and divide it by 2/3 then you get 1/5

Answer:

  122 = 2(2w +w)

Step-by-step explanation:

If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.

  P = 2(L+W)

  122 = 2(2w +w) . . . . an equation for the description

Answer:

see explanation

Step-by-step explanation:

The sum of the areas of the 2 rooms is

(1 [tex]\frac{1}{4}[/tex] )² + 6² ← change the mixed number to an improper fraction

= ([tex]\frac{5}{4}[/tex] )² + 6²

= [tex]\frac{25}{16}[/tex] + 36

= 1 [tex]\frac{9}{16}[/tex] + 36

= 37 [tex]\frac{9}{16}[/tex]

Answer:

Only students who have a recess at 12:00 pm or later may go outside

Step-by-step explanation:

it is 18 degrees at midnight and the temp. increases 1.2 every hour.

so 1.2 times 12 hours equal 14.4

add 14.4 to 18 drgrees equal 32.4

Answer:

2 years

Step-by-step explanation:

If you have $9000 in the saving account, and you take $500, you are left with:

$9000 - $500 = $8500

in one year you will have 3% more of the 8500 which is:

8500/100*3 = $255

so in one year the number on your savings account is:

8500 + 255 = $8755

and by the next year you will have 3% more of the 8755 which is:

8755/100*3 = $262.65

so in two years the number on your savings account is:

8755 + 262.65 = $9017.65

which is a little bit more than the $9000.

so it will take 2 years until the calance again reaches $9000

Please mark braniliest if this reaches 2 answers because I want to get to Expert ;w;

Answer:

  - 250

Step-by-step explanation:

Pick two points along the line of the graph

(4,7000) and (8,6000)

Using the slope formula

m = (y2-y1)/(x2-x1)

    = (6000-7000)/(8-4)

    -1000/4

   - 250

Answer:

-250

Answer:

50 + 1 + [tex]\frac{2}{10}[/tex] + [tex]\frac{4}{100}[/tex] + [tex]\frac{2}{1,000}[/tex]

Step-by-step explanation:

This is the answer because:

1) 50 and 1 equal to 51

2) The fraction forms of a decimal number is: the decimal number/the decimal number place value

3) Therefore, the answer is 50 + 1 + [tex]\frac{2}{10}[/tex] + [tex]\frac{4}{100}[/tex] + [tex]\frac{2}{1,000}[/tex]

Answer:

  1 1/8 hours

Step-by-step explanation:

The relationship between time and speed and distance is ...

  time = distance/speed

Then Alex's time is ...

  time = (2.25 mi)/(2 mi/h) = 1.125 h

It will take Alex 1 1/8 hours to walk to school at 2 mph.

Answer: It’s B

Step-by-step explanation:

I just did the quiz

Answer:

The answer would be B

Step-by-step explanation:

take a look at your question.

If you look at the x axis you can see that it is 12 but c is also that.

Now take a look at the y axis, you can see that the letter B is connected to 18.

If you remember your previous problems you would remember that that was an answer (12, 18). But for those who do not remember you can multiply 2x6(which you got your 12 from) and 3x6 ( which is where the 18 is from)

So there for you are left with the answer B.

Let me know if this helped!!! :))))

Answer:

He started climbing 9 feet up into the tree, so we can assume that the initial position is 9ft above the ground.

Then if he wants to get back into the ground, he must "descend" or climb down 9 ft again.

Then the integer is -9 (because he is climbing down now).

In this case, the 0 represents that he does not move.

So the integer 0 is related to: +0ft or -0ft

This means that he climbs up 0ft or down -0ft, which is the same as not moving at all.

Answer:

The rate of survival without brain damage

Step-by-step explanation:

The response variable (or dependent variable) is the variable that is measured and which depends on other variables. In this experiment, the researchers are investigating the impact of reducing body temperature on rate of survival without brain damage. The variable that they were 'measuring' was the rate of survival without brain damage, which depended on the variable of reducing body temperature, therefore the response variable here is the 'rate of survival without brain damage.'

Answer:

[tex]\boxed{14}[/tex]

Step-by-step explanation:

→ Remember multiplication occurs first

[tex]7+3*5-4*2=7+15-8[/tex]

→ Simplify the remaining expression

[tex]7+15-8=22-8=14[/tex]

Answer:

it depends

Step-by-step explanation:

If 17 is the hypotenuse

[tex]c=17\\\\b=12\\\\a=?\\\\c^{2} =a^2+b^2\\\\17^2=a^2+12^2\\\\17^2-12^2=a^2\\\\(17-12)(17+12)=a^2\\\\5(27)=a^2\\\\a=\sqrt{9*3*5} \\\\a=3\sqrt{15} \\\\a=11.6[/tex]

if you are looking for the hypotenuse

[tex]a=17\\\\b=12\\\\c=?\\\\a^2+b^2=c^2\\\\17^2+12^2=c^2\\\\289+144=c^2\\\\433=c^2\\\\c=\sqrt{433} \\\\c=20.8[/tex]
