Ans The Question............very Urgent

Answers

Answer 1

Answer:

It's false.

Step-by-step explanation:

By breaking the middle term.

Put the root into equation, if it equals 0, then it's a root.

2x^2+3x-1=0

2(1/2)^2+3(1/2)-1=0

2(1/4)+3/2-1=0

2/4+3/2-1=0

1/2+3/2-1=0

(1+3-1*2)/2

4-2/2 = 1

1 is not equal to 0.

If £2000 was put into a bank acount that pays 3% compound intrest per year, how much will be in the account after 2 years

Answers

Answer:

After 2 years, there will be £ 2,121.80 in the account.

Step-by-step explanation:

Since £ 2000 was put into a bank account that pays 3% compound intrest per year, to determine how much will be in the account after 2 years the following calculation must be performed:

2000 x (1 + 0.03 / 1) ^ 1x2 = X

2000 x 1.03 ^ 2 = X

2,121.8 = X

Therefore, after 2 years, there will be £ 2,121.80 in the account.

What statements about prisms are always true if the top base is directly above the bottom base? Select all that apply. The lateral faces are rectangles. The bases are congruent. The bases can be any shape. The lateral faces are congruent.

Answers

Answer:

The bases are congruent

Step-by-step explanation:

From the question, we understand that the top base and the bottom base are directly opposite one another.

When such a scenario arise, it means that the bases have the same shape, they have the same dimension (i.e. size).

With the above analysis, we can conclude that the bases are congruent.

However, the given information can not be used to determine the shape and congruence of the lateral faces.

Lastly, for the bases to be congruent, they must have the same shape (and not any shape).

Hence, only option (b) is correct

What is the measure, in degrees, of ZA?

Answers

Answer:

28

Step-by-step explanation:

2x + 3x + 40 =180

5x= 180 - 140

5x=140

x= 28

Answer:

Step-by-step explanation:

We know that the sum of interior angles of a triangle is 180° so we can say:

40 + 2x + 3x = 180°

40 + 5x = 180°

5x = 140°

x = 28°

Now substitute in 28 for the value of x in Angle A:

=> 2x would become 2(28)

=> 56° = ∠A

The baseball team has a double-header on Saturday. The probability that they will win both games is 42%. The probability that they will win just the first game is 60%, What is the probability that the team will win the 2nd game given that they have already won the first game?​

Answers

This problem fits the conditional probability formula very well. The formula is P(B|A) = P(B ∩ A)/P(A). If event A is winning the first game, and event B is winning the second, then P(B ∩ A) = 0.44, and P(A) = 0.6. So P(B|A) is obtained by dividing 0.44 by 0.6, which is about 0.733.

Answer:

24%

Step-by-step explanation:

assign a variable x:

Find the average and solve for x by isolating the variable:

(x+60%)÷2=42%

multiply on both sides, left side cancels, multiply right side

(x+60%)÷2 *2= 42%*2

x+60% = 84%

subtract on both sides, left side cancels, subtract right side

x+60% - 60%=84% - 60%

x=24%

Missy is saving to attend a week at summer camp. She needs $250.00 to register. Her parents will contribute $75.00. She needs to raise the rest of the money babysitting for $12.00 per hour. What is the minimum number of hours she must babysit in order to attend camp?

Answers

Answer:

At least 15 hours

Step-by-step explanation:

First, subtract the $75 that her parents will contribute:

250 - 75

= 175

So, from babysitting, she will have to raise $175

Divide this by 12 to find how many hours she has to babysit:

175/12

= 14.583

We have to round this up to a whole number, which will be 15.

So, Missy will have to babysit for a minimum of 15 hours

Answers

Answer:

1) The stars are not constant in their position.

2) No. The stars aren't in original position because of apparent movement of stars in the sky.

3) Due to rotation of earth on its axis , the stars appear to move from west to east in the sky. Actually stars don't move as they are constant in their position but they appear to move with respect to earth.

4) Both the motion of stars & motion of sun are similar because both are an example of apparent motion. Both appear to change their respective positions but in reality , sun & stars are constant in their positions. But as earth is rotating , it appears like sun & stars are changing their positions.
