Answer:

answer: 1/4

Step-by-step explanation:

Hello Love! The answer would be 1/4 because each time when flipping the coin you have a probability of 1/2 because you have equal chances of getting heads or tails then you multiply 1/2 by 1/2 and get 1/4

Answer: 1/4

Step-by-step explanation: In this problem, we are flipping a coin and we want to find the probability of flipping heads and heads.

Flipping a coin twice are events because the outcome of flipping 1 coin

does not affect the outcome of flipping the other coin.

First, find the probability of each event.

The probability of flipping headsnon the first coin toss is 1/2 since there

is 1 favorable outcome, flipping heads, and 2 possible outcomes.

The second flip will also be 1/2.

Now multiply the probabilities to get 1/4.

Answer:

2x² + 23

Step-by-step explanation:

Distribute the -5 and combine like terms.

7x² + 3 - 5(x² - 4) =

= 7x² + 3 - 5x² + 20

= 2x² + 23

Answer:

40.5

Step-by-step explanation:

there are 4 laps in 200 metres.

(200m÷50m)

2min 42 sec=120 sec+42sec (162sec)

so,

162÷4=40.5

Write an expression for 213 increased by d: [tex]213+d=x[/tex]

Answer:

38 cm

Step-by-step explanation:

The perimeter is the sum of the sides

Starting from the left and going clockwise, then

9 + (10 - 6) + (9 - 2) + 6 + 2 + 10

= 9 + 4 + 7 + 6 + 2 + 10

= 38

Answer: 35 cm

Step-by-step explanation: to find the perimeter you add all the sides but sense there is on side that doesn't have a number you subtract 2 from nine then add all the sides plus 7.

Given:

Angle 1 = 90 (An)

Angle 2= 45 (An)

Angle 3 = 36 (An)

Angle 4 = 50 (An)

Angle 5 = 20 (An)

Answer:

Step-by-step explanation:

A person invested $2,500 in an account growing at a rate allowing the money to double every 11 years. How long, to the nearest tenth of a year would it take for the

value of the account to reach $3,800?

The formula for exponential growth given as:

A(t) = Ao (1/2)^t/t½

A(t) = Amount after time t = $3,800

Ao = Initial amount invested = $2500

t = Time in years

t½ = Time it takes to double = 11 years

Hence,

3800 = 2500(1/2)^t/11

Divide both sides by 2500

3800/2500 = 2500(1/2)^t/11/2500

Answer:

C

Step-by-step explanation:

Answer:

C:  none

Step-by-step explanation:

Here we have two separate functions named 'y.'  Eliminate 'y' temporarily by equating these functions together:

x + 2 = y = x - 1

Subtracting x from both sides, we get:

0 + 2 = y = 0 - 1, or

       2 = -1

This is never true, so C is the correct answer:  NO solutions.

An easier way in which to do this problem is to visualize the graphs of

y = x + 2 and y = x - 1.  The graphs are parallel straight lines; they never intersect, and therefore we can conclude "no solution."

Answer: 11

Step-by-step explanation:

Answer:

Step-by-step explanation:

The figure drawn is a circle.  It's center is a (-5,4) just the opposite of what is in the brackets.  I'm giving you this information just to be complete.

For a circle the radius is found using the lone number on the other side of the equal side -- in this case 121

The radius is the square root of that lone number.  

radius^2 = 121

sqrt(radius^2) = sqrt(121)

radius = 11

Step-by-step explanation:

√196 = 14

√169 = 13

√121 = 11

√225 = 15

√144 = 12

√100 = 10

Answer:

Hope this helps!!!

Have a great day!!!

√196=14

14*14=196

√169=13

13*13=169

√121=11

11*11=121

√225=15

15*15=225

√144=12

12*12=144

√100=10

10*10=100

Answer:

93

Step-by-step explanation:

both of the angles are on a straight line. Therefore, together they add up to 180°. So 180°-87°=93°

Answer:

36

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Let the number be x, then

First subtract 14 from number x, then

x - 14

Now multiply difference by -2, results -44

(x - 14) × -2 = -44

By solving equation,

-2X + 28 = - 44

- 2X = -44 - 28

X = -72 ÷ -2

x = 36

So, Peter's number is 36.
