HeLP me ASAP PLEASE ASAP i will give 50 points for the right answer

Answer:

with T = 50⁰C, we have:

50 = 200 - 5x - x²

<=> x² + 5x = 150

<=> x² + 5x - 150 = 0

=> x = 10

Answer:

16

Step-by-step explanation:

8/ 2*(2+2) = 4*(2+2) = 4*4 = 16

Answer:

NPV, IRR, payback.

Step-by-step explanation:

The best worst decision technique involves the choice modelling. In terms of the overall usefulness in the capital budgeting decisions,

-- the decision rule that is best is the NPV

-- the decision rule that is worst is payback period

The NPV capital budgeting tool provides accurate results and it also assumes cash flow can be reinvested at a discount rate.

The IRR is the second best budgeting tool where it assumes that the cash flows can be reinvested at IRR.

And the worst is the payback where it does not take into account its time value of the money and so it does not yield the correct as well as accurate results.

Therefore, ranking the rules from best to worst is : NPV, IRR, payback.

Answer:

2/51

Step-by-step explanation:

# of brown socks = 4

# of blue socks = 14

total # of socks = 18

The probability of pulling 1 brown sock = 4/18

If he were to pull one brown sock there would be 1 less sock in the total # of socks and 1 less in the # of brown socks

So after the first pull ( if it were to be a brown sock )

there would only be 3 brown socks and 17 total socks

So the probability of pulling a brown sock then would be 3/17

Finally we multiply the two probabilities to get the answer

4/18 * 3/17 = 2/51

Hence, the answer is 2/51

Answer:

0.8

Step-by-step explanation:

80 percent is 80/100. Decimal point 100 would be just 1. Hence 80 percent would be 0.8/

Answer:

solution given:

Area of triangle ABC=½b×h=½×18×21=189km²

Area of square DEFG=l²=9²=81km²

Area of rectangle DHIJ=l×b=4×13=52km²

Total area =189+81+52=322 square kilometers.

Answer:

322 sq. km

Step-by-step explanation:

the area of fig. =

(½×18×21)+(13×4)+(9×9)

= 189+52+81

= 322 sq. km

Answer:

RN ≈ 4.2

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos65° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RN}{PR}[/tex] = [tex]\frac{RN}{10}[/tex] ( multiply both sides by 10 )

10 × cos65° = RN , then

RN ≈ 4.2 ( to 1 dec. place )

Answer:

89 m²

Step-by-step explanation:

Area of rectangle = 8 x 13 = 104

Area of triangle = (5 x 6) / 2 = 15

104 - 15 = 89 m²

Answer:

63/3465

Step-by-step explanation:

A small pond contains nine catfish and two bluegill.

Total number of fish = 9 catfish + 2 blue hill

= 11 fishes

Probability of picking one catfish = P(C) = P(9/11)

Probability of picking one bluegill = P(B) = P(2/11)

If nine fish are caught at random, the probability that all of them are catfish is calculated as:

= P(9 Catfish) = 9/11 × 8/10 × 7/9 × 6/8 × 5/7 × 4/6 × 3/5 × 2/4 × 1/3

= 362880/19958400

Further simplifying to the simplest fraction:

= 189/10395

= 63/3465

Answer:

Let represent the number of minutes until Cassie’s distance to Ben is twice that of Abby’s distance to Ben. In minutes Abby will walk m and Cassie will walk m. The following diagram contains the information showing Abby’s position, , Ben’s position, , and Cassie’s position, , at time .

A right-angled triangle is formed by joining Abby's initial position to points A and B. Its hypotenuse is A B and its other sides are of length 100 and 20 times t. Another right-angled triangle is formed by joining Cassie's initial position to points C and B. Its hypotenuse is B C and its other sides are of length 160 and 41 time. Represent Abby, Ben and Cassie’s respective positions at noon as points on the -axis so that Ben is positioned at the origin , Abby is positioned units left of Ben at and Cassie is positioned units right of Ben at .

solution 2

Let represent the number of minutes until Cassie’s distance to Ben is twice that of Abby’s distance to Ben.

In minutes Abby will walk south m to the point . In minutes Cassie will walk north m to the pointTherefore, in

minutes ( minutes seconds), Cassie’s distance to Ben will be twice that of Abby’s distance to Ben. .

Answer:

The baby gained 29 oz.

Step-by-step explanation:

1 pound is equal to 16 oz (ounces).

10 pounds is equal to 10 x 16 oz = 160 oz.

8 pounds and 3 oz is equal to (8 x 16) + 3 = 128 + 3 = 131 oz.

160 oz - 131 oz = 29 oz.

The baby gained 29 oz.

Fixed Deposits have a fixed lock-in period, which limits the unnecessary withdrawal of your money until maturity. A savings account, on the other hand, enables you to withdraw any amount at any time, which proves detrimental to your goal of wealth appreciation.

Answer:

first statement

Step-by-step explanation:

The absolute value of - 6 is | - 6 | = | 6 | = 6

The absolute value is always positive as it is a measure of the distance from the origin to - 6 and distance is always positive.

It is not the distance between 6 and - 6 on the number line.

Answer:

[tex]\sqrt{6}[/tex] units = g

Step-by-step explanation:

You can solve this either of the 2 ways:

#1.) Sin(60) = g/[tex]2\sqrt{2}[/tex]

=> Sin(60) * [tex]2\sqrt{2}[/tex] = g

=> [tex]\sqrt{6}[/tex] = g

#2.) Cos(30) = g/[tex]2\sqrt{2}[/tex]

=> Cos(30) * [tex]2\sqrt{2}[/tex] = g

=> [tex]\sqrt{6}[/tex] = g

Hope this helps!
