ffice building in New York City. The company believes it has a​ 40% chance of winning the hotel bid and a​ 25% chance of winning the office building bid.

Answer: Our required probability is 0.55.

Step-by-step explanation:

Since we have given that

Probability that chance of winning the hotel bid = 40%

Probability that no chance of winning the hotel bid = 100-40=60%

Probability that chance of winning the office building bid = 25%

Probability that no chance of winning the office building bid = 100-25 = 75%

So, Probability that the company will win at least one contract is given by

0.4\times 0.75+0.6\times 0.25+0.4\times 0.25\\\\=0.55

Hence, our required probability is 0.55.

Answer: C

Step-by-step explanation:

Okay first set a comparison since the two triangles are similar

x-1/20=x-1+27/3x+8

x-1/20 = x+26/3x+8

cross multiply

20x+520=3x^2+8x-3x-8

3x^2-15x-528=0

3(x^2-5x-176)=0

im kinda lazy to factor this out so i used an online calculator right here but factor it out like a good kid

x=16, x=-11

it has to be positive so x=16

Which of the following is the solution to the compound inequality below
Vaselesa [24]

So starting with the first inequality:


Firstly, subtract 1/5 on each side. \frac{3}{2}x \geq -\frac{6}{5}


Next, multiply each side by 2/3, and your answer should be:

x \geq -\frac{12}{15}\\\\ x \geq-\frac{4}{5}



Second inequality:


Firstly, add 7/3 on each side -\frac{1}{2} x\geq \frac{22}{3}


Next, multiply by -2 on each side, and flip the less than or equal to sign because you are multiplying by a negative. Your answer will be x\leq -\frac{44}{3}


In short, the correct option is the first option.

Carol is baking cookies and needs 2 1/4 cups of flour 2/3 cup of white sugar 1/4 cup of brown sugar and 1/16 cup of baking soda
andre [41]

1) Amount of white sugar ÷ the amount of brown sugar =

\frac{2}{3}÷\frac{1}{4}

=\frac{2}{3}.\frac{4}{1}= \frac{8}{3}=2\frac{2}{3}.

2)Amount of white sugar after increase =

\frac{2}{3}+2\frac{1}{2}=\frac{2}{3}+\frac{5}{2}=\frac{19}{6}=3\frac{1}{6}.

3)Amount of flour after increase=2\frac{1}{4}+2\frac{1}{2}=\frac{9}{4}+\frac{5}{2}=\frac{19}{4}=4\frac{3}{4}.

4) Amount of brown sugar =

\frac{1}{4} cup.\frac{1}{4}of\frac{1}{4}=\frac{1}{16}

\frac{1}{16} cup was used .

5)Amount of Baking soda used=

\frac{1}{4}of\frac{1}{16}=\frac{1}{64}
