Answer: To problem wants to compute the probability of the expected value that could be earn if you would draw again another card. So base on the fact that if draw a face card of K,Q,J from a standard deck correctly you will earn 10 point in just one draw, but loose 2 points if you another card, the probability that you would draw correct card in just one draw is 30.77%, so the possible value earn you have 2 points only

A meter stick casts a shadow 1.4 m long at the same time a flagpole casts a shadow 7.7 m long. The triangle formed by the meterstick and its shadow is similar to the triangle formed by the flagpole and its shadow. How tall is the flagpole?

These two triangles are similar, so their ratios are equal.

7.7 / 1.4 = x / 1, where x = the flagpole length

multiply by one and simplify

x = 7.7 / 1.4

7.7 / 1.4 = x / 1, where x = the flagpole length

multiply by one and simplify

x = 7.7 / 1.4

X/20 +4(2x)/20 + 10(x+1)/20+-4x/20

The correct answer should be 15 i think... hope this helps :)

They all have the same common denominator so we can just add the numerators.

X+ 8x+10x+1-4x/20=

Combine like terms

15x+1/20

X+ 8x+10x+1-4x/20=

Combine like terms

15x+1/20

the length of a rectangle is 3 times the width. The perimeter is 44 cm. What are the dimensions of the rectangle?

Hello there

We can say that,

The length = 3u

The width= 1u

3u + 1u +3u +1u= 44cm

8u= 44cm

1u= 44cm / 8

= 5.5cm

Length= 5.5 cm x 3

=16.5 cm

Width= 5.5 cm

Hope this helps :))

We can say that,

The length = 3u

3u + 1u +3u +1u= 44cm

8u= 44cm

1u= 44cm / 8

= 5.5cm

Length= 5.5 cm x 3

=16.5 cm

Width= 5.5 cm

Hope this helps :))

44:(3+1)=11 cm is width

11*3=33 cm is length

Dimensions of the rectangle are

width: 11 cm

length: 33 cm

11*3=33 cm is length

Dimensions of the rectangle are

width: 11 cm

length: 33 cm

Find the sum (3x^2+5x-8)+(5x^2-13x-5)

8x^2-8x-13 is the correct answer

No need to fear I'll help you get through this problem :D

Okay so this is the original problem, let's work down from it....

(3x² + 5x - 8) + (5x² - 13x - 5)

**** Remember we need to add only the values that have like variables of the same exponents ****

(8x² - 8x - 13)
