The lengths of the sides of a triangle are 3, 3, and the square root 3. Can the triangle be a right triangle?

First find the decimal equivalent of square root 3: SQRT(3) = 1.732 ( roughly)

If the base and height were each 3, then the hypotenuse would need to be:

3^2 + 3^2 = C^2
9 + 9 = C^2
18 = C^2
C = SQRT(18) = 4.24

This is larger than sqrt(3), so this cannot be a right triangle.

If one leg was 3 and the other leg was sqrt(3) then the hypotenuse would be:
3^2 + 1.73^2 = C^2
9 + 3 = C^2
12 = C^2
C = SQRT(12) = 3.46

This is larger than 3, this cannot be a right triangle.

The answer is b) no.

No
Because it does not obey Pythagoras theorem (a^2 + b^2 = c^2)

HELP ASAP NOW NOW NOW NOW!!! Suppose three riders rode a total of 182 miles.

Sav [38]

Answer:

14 miles

Step-by-step explanation:

Assuming each horse was only ridden once

then a total of 13 horses were ridden for a total of 182 miles

182 miles / 13 horses = 14 miles horse

Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.

Note that the fact that there were 3 riders is irrelevant.

Maths<br>-|-30-(10-20)|-|5-(10-15)|=?<br>If someone helped me , I would be grateful

defon

Answer:

-30

Step-by-step explanation:

-|-30-(10-20)|-|5-(10-15)|=-|-30-(-10)|-|5-(-5)|

=-|-30+10|-|5+5|

=-|-20|-|10|

=-(20)-(10)

= -20-10

= -30

Jordan would like to buy an oil painting with an original price of $744.00. Which coupon should he use 55% off or $400.00

Ksivusya [100]

Answer:

The 400 coupon is 80 cents better

Step-by-step explanation:

First find the sale price with the coupon

744 - 400 = 344

Now find the sale price with the discount

100-55 = 45

We will pay 45% of the original price

744*45%

744*.45

344.80

A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only

<h3>What is a fraction?</h3>

A fraction is a portion of a whole or, more broadly, any number of equal parts.
In everyday English, a fraction represents the number of pieces of a specific size, such as one-half, eight-fifths, or three-quarters.
A common, vulgar, or simple fraction that consists of a numerator above a line and a non-zero denominator below that line.
Numerators and denominators are also employed in uncommon fractions such as compound fractions, complex fractions, and mixed numerals.

To find what fraction of the marbles now in the bag is blue:

Important information is that immediately before the last step blue marbles formed $\frac{1}{5}$ from the marble in the bag.
That means that there were $x$ blue and $4x$ other marbles, for some $x$ .
When we double the number of blue marbles, there will be $2x$ blue and $4x$ other marbles.
Hence, blue marbles now form $\frac{1}{3}$ all marbles in the bag.

Therefore, (C) $\frac{1}{3}$ fraction of the marbles now in the bag is blue.

Complete question:

A bag initially contains red marbles and blue marbles only, with more blue than red. Red marbles are added to the bag until only 1 / 3 of the marbles in the bag are blue. Then yellow marbles are added to the bag until only 1 / 5 of the marbles in the bag are blue. Finally, the number of blue marbles in the bag is doubled. What fraction of the marbles now in the bag are blue?

(A) 1/5

(B) 1/4

(D) 2/5

(E) 1/2
