Use the conditional statement to answer the question.

1 answer:

6 0

The original statement is true by the definition of what constitutes a right angle. It's simply set up this way.

The contrapositive would be the statement "if the angle does not measure 90 degrees, then the angle is not a right angle" which is also a true statement. Example: a 37 degree angle is not a right angle.

Note: the original conditional "If P, then Q" would have the contrapositive be in the form "If not Q, then not P". We flip P and Q, and stick "not"s in front of both parts.

So this is why the answer is choice D

Need some help with this question in the image Cheers

iren [92.7K]

Step-by-step explanation:

a) 24.7×52.3=1291.81

On rounding off to 3 significant digits we get

1290

$\sqrt{ {42}^{2} - {28}^{2} }$

$\sqrt{1764 -784 } = \sqrt{980}$

=31.304951

On rounding off to 5 significant figures we get

=31.305

$\sqrt[3]{78} = 4.27265$

On rounding off to 2 significant figures we get

=4.3

Hence required answers

a)1290

b)31.305

c)4.3

I hope it helped you

Three good friends are in the same algebra class. Their scores on a recent test are three consecutive even integers whose sum is

klio [65]

Let the lowest score be x.

The 3 consecutive even scores are:

1st score = x

2nd score = x + 2

3rd score = x + 4

Sum of their score is 270:

x + (x + 2) + (x + 4) = 270

Solve x:

x + (x + 2) + (x + 4) = 270

x + x + 2 + x + 4 = 270

3x + 6 = 270

3x = 264

x = 88

Find their scores:

1st score = x = 88

2nd score = x + 2 = 88 + 2 = 90

3rd score = x + 4 = 88 + 4 = 92

Answer: The scores are 88, 90 and 92
