Evaluate 1/5t + 1/10 when t= 1/2

Answer:

x=2 or x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−4=0

Step 1: Add 4 to both sides.

x2−4+4=0+4

x2=4

Step 2: Take square root.

x=±√4

x=2 or x=−2

Answer:

The Zero Product Property states that if ab = 0, then either a = 0 or b = 0, or both a and b are 0. When the product of factors equals zero, one or more of the factors must also equal zero. Once the polynomial is factored, set each factor equal to zero and solve them separately.

X=3

60*3= 180

Answer:

neither; neither; supplementary

Step-by-step explanation:

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.

First picture: 32° + 48° = 80°

80° < 90° and 80° < 180°

Therefore they are neither

Second picture: 101° + 77°  = 178°

178° > 90° and 178° < 180°

Therefore they are neither

Third picture: 107° + 73° = 180°

180° < 90° but 180° = 180°

Therefore they are supplementary

neither neither and supplementery cus i smrt

Answer:

Answer: Choice C.   (3,-2)

A diagram is shown below.

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

Explanation:

There are two approaches we can take. Since we're given a list of choices, we can plug each of the coordinates one at a time into the inequality. If we get a true statement, then it is a solution.

For choice A, we have x = 2 and y = 3 paired up together. Plugging them into the given inequality leads to...

y < (-1/2)*x + 2

3 < (-1/2)*2 + 2

3 < -1 + 2

3 < 1

This is false because 3 is not smaller than 1. So (2,3) is not a solution. You should find that choice B leads to a similar situation because

y < (-1/2)*x + 2

1 < (-1/2)*2 + 2

1 < -1+2

1 < 1

and 1 cannot be smaller than itself. So (2,1) isn't a solution either.

However, choice C is the answer since,

y < (-1/2)*x + 2

-2 < (-1/2)*3 + 2

-2 < -1.5 + 2

-2 < 0.5

This is true because -2 is to the left of 0.5 on the number line. So that's why (3,-2) is a solution.

For choice D, you should find that (-1,3) doesn't make the inequality true.

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

An alternative approach:

As a visual way to solve this problem, we can graph the given inequality by following these steps

We make the boundary line dashed because points on the boundary do not count as solution points. This is due to the lack of "or equal to" in the inequality sign. We shade below the boundary line because of the "less than".

As the diagram below indicates, the blue region consists of every (x,y) solution point that makes y < (-1/2)*x + 2 true.

The diagram also shows that only point C is in that blue region, making it a solution point. Point B on the boundary does not count as a solution. You can think of the dashed line as an electric fence you can only get closer to, but can't touch, in terms of determining a solution point.

So effectively, this is a quick and easy way to find solutions if you have a graphing calculator or online graphing tools (such as Desmos or GeoGebra).

Answer:22

Step-by-step explanation:

Answer:

x=22

Step-by-step explanation:

add 38 to both sides

you'll have 3x=66 after adding

then divide both sides by three so have x by itself and you'll get

x=22

Answer:

5 - x=90°

6- angle c= 75°

7- angle a = 90°

Answer:

c = 75

Step-by-step explanation:

All triangles add up to 180. Add the two angles which you have, and then subtract that from 180. that will be your third angle value.

Answer:

Probability of spinning a odd number is 5/9

I don't know about flipping head

Probability of spinning a 3 is 1/9

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

Explanation:

The sample space of the spinner is {1,2,3,4,5,6,7,8,9} which represents all the possible outcomes. We can only pick one of those values. Of that list, the subset {1,3,5,7,9} represents all the odd numbers. This is the event space because we want to land on an odd number.

There are 5 items in the event space and 9 items in the sample space. The probability of getting an odd number is 5/9.

The probability of flipping heads is 1/2 since we have one side we want (heads) out of two sides total.

Lastly, the probability of landing on a '3' is 1/9 because there's only one '3' out of 9 values total.

---------

We'll multiply those fractions to get the final answer. This works because each event is independent of one another.

(5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Now use your calculator to find that: 5/162 = 0.030864 approximately which rounds to 0.0 or just 0 when rounding to the nearest tenth.

Unfortunately this is one case where rounding will creates a misleading result. The true probability isn't 0 because the events described are possible. The probability is just really small.
