​

Answer:

16

Step-by-step explanation:

[tex]x2 + 10 \\ = 3 \times 2 + 10 \\ = 6 + 10 \\ = 16[/tex]

Answer:

16

Step-by-step explanation:

You plug 3 in for x and then you have (3)2+10 and 3 times 2 is 6 plus ten is 16

77 = 7b

9 = b - 2

Answer:

12

Step-by-step explanation:

There are 6 outcomes for the cube and 2 outcomes for the coin

6*2 = 12

There are 12 different outcomes total

Answer:

178

Step-by-step explanation:

Supplementary angles add to 180 degrees

Let x be the supplement to 2

2+x = 180

Subtract 2 from each side

2+x-2 = 180-2

x = 178

Answer: (1,-1/2)

Step-by-step explanation:

Point C on the coordinate plane has the coordinates (4,-2) after a dilation with a scale factor of 1/4 we will have to multiply the coordinates each by 1/4 to find the new coordinates.

So x =  4 * 1/4 = 1   Now the new x coordinate is 1  

-2 * 1/4 =  -2/4 = -1/2      Now the new coordinate for y is also -1/2

So we will now have the coordinates (1,-1/2)

Step-by-step explanation:

Rationalization.  

                                                                              2 + i

For example:  " rationalize the denominator of ---------  "

                                                                               -3 + i

Answer:

Rational numbers: fractions with an integer numerator and a nonzero integer denominator.

Irrational numbers: numbers that are not rational such as π, root 3, and any non repeating, non ending decimal.

Answer:

The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C

Step-by-step explanation:

From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.

Now, if the temperature increases by 2.9 C each hour,

Then, after 3 hours, the temperature of the chemical solution would have increased by

2.9 C/h × 3 h

8.7 C

Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.

The temperature of the chemical solution after 3 hours will be

-14.96 C + 8.7 C

= -6.26 C

≅ -6 C (to the nearest whole degree)

Answer:

I'm not sure about this one but you can try a=40

Step-by-step explanation:

Answer:

a = 30°

Step-by-step explanation:

Sum of the angles in a triangle is 180°

32° + 2a - 17 + 180° - ( a + 45° ) = 180°

32 + 2a - 17 = a + 45

a = 45 + 17 - 32

a = 30°

Answer:

28 cm

Step-by-step explanation:

vertical side of each parallelogram is (y-6)/2 cm

perpendicular height of each parallelogram is 7 cm

Total area = 4sh

308 = 14(y-6)

y-6 = 22

y = 28 cm

Step-by-step explanation:

Answer:

1/26 ; 1/26 ; 1/52

Step-by-step explanation:

Given the following :

A deck of 52 cards contains :

Red hearts, Red stars, black triangles, black circles

Each type of card is numbered from 1 - 13

Therefore,

Number of each type of card = 13, all numbered distinctly with digits between 1 - 13

Probability = (number of required outcomes / total number of possible outcomes)

If one card is drawn from the deck:

Probability of picking a red one :

This is either a red heart numbered 1 or a red red star numbered 1,

Therefore, Required outcomes = 2

Total possible outcomes = 52

P(a red one) = 2 / 52 = 1/26

B) A black three

This is either a black triangle numbered 1 or a black heart numbered 1,

Therefore, Required outcome = 2

Total possible outcomes = 52

P(a black three) = 2 / 52 = 1/26

C.) A six of hearts :

A hearts numbered six = 1

Therefore, Required outcome = 1

Total possible outcomes = 52

P(a black three) = 1 / 52 = 1/52

Answer:

A.   x = 5

Step-by-step explanation:

2 + 8x = 11x - 13   -------- subtract 2 from both sides

2 + 8x - 2 = 11x - 13 - 2

8x = 11x - 15         -------- subtract 11x from both sides

8x - 11x = 11x - 15 - 11x

-3x = -15

x = -15 / -3

x = 5

Answer:

x=5

Answer:

The SQ Root of 493

Step-by-step explanation:

Becaues this triangle is a right triangle, we can find the missing side usiing the pythagorean theorum.

The pythagorean theorun states A^2 + B^2 = C^2, so 18^2 + 13^2= 439

Then all you have to do is find the sq root of 439, but this question askes you not to.

Hope this helps :)

Answer:

y = 3/2x -5/2

Step-by-step explanation:

Slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

3x- 2y = 5

Solve for y

Subtract 3x from each side

3x -3x- 2y =-3x+ 5

-2y = -3x+5

Divide by -2

-2y/-2 = -3x/-2 +5/-2

y = 3/2x -5/2

Answer:

7 hours

Step-by-step explanation:

810 - 180 = 630

630/ 90 = 7

Answer:

x = 7 h

Explanation:

First, we write the data of the problem.

Alex travels 810 miles away

Train - 90 miles / h

Alex covers 180 miles.

How many hours does Alex walk in the distance?

1. Calculate the distance Alex still has to travel.

 810 miles - 180 miles = 630 miles

2. We take into account the speed of the train to calculate how many hours Alex will cover the remaining distance.

90 miles .... 1 h

630 miles .... x h

x = 630 milesx1h / 90 miles

x = 7 h

[tex]\large \boxed{\mathrm{mines}}[/tex]

Step-by-step explanation:

Possessive pronouns are pronouns that indicate relationship or ownership.

Don’t take it this book is mines.

To convert mm to m, divide by 1000:

794/1000 = 0.794 m

1 day = 24 hours

1 hour = 3600 seconds

24 x 3600 = 86,400 seconds in a day

Answer:

Step-by-step explanation:

To convert 794mm into m

1000mm = 1m

794mm = xm

m = 794/1000

m = 0.794m

One day to secs is

= 84,400secs

Answer:

Christopher Columbus

Step-by-step explanation:

According to the hystoriartors:

Christopher Columbus

Answer:

[tex]Christopher[/tex] [tex]Columbus[/tex] [tex]and[/tex] [tex]Leif Eriksson[/tex]

Step-by-step explanation:

[tex]we[/tex] [tex]celebrate[/tex] [tex]columbus[/tex] [tex]day[/tex]

Columbus Day is for Christopher Columbus, who had discovered America.

Leif Eriksson was the first one who found America. While most people think it might have been Columbus. In conclusion, Leif Eriksson discovered America (well, Columbus gets some credit too for finding America.)

The answer to your question: Leif Eriksson, or Columbus.

Leif Eriksson found America Half a millennium before Columbus.

So let’s just take it as... that they both were one of the ones to find America :)

Hope this helps!

Answer:

[tex] x = 2 [/tex]

Step-by-step explanation:

Figure B = 2½ the size of figure A

One side of figure B is given as 5, therefore, 5 = 2½ of x in figure A.

Thus, [tex] 5 = 2\frac{1}{2}*x [/tex]

Solve for x

[tex] 5 = \frac{5}{2}*x [/tex]

[tex] 5*2 = \frac{5x}{2}*2 [/tex]

[tex] 10 = 5x [/tex]

[tex] \frac{10}{5} = \frac{5x}{5} [/tex]

[tex] 2 = x [/tex]

[tex] x = 2 [/tex]
