If two sides in one triangle are 9 and 21 , then the third side might be
a) 9
b) 11
c) 12
d) 13
please explain how you got the answer in details I'm completely lost

Answers

Answer 1

Answer:

13

Step-by-step explanation:

there is a rule that says that if you add any 2 sides, it should be more than the third. 9+21 is greater than 13. 21+13 is greater than 9. 13 is the only number which if you add 9 to it it will be greater than 21. 12 will equal 21, but it still wont work.

hope this helps :))

Step 1 of 2: Using the standard form ax2+bx+c=0 of the given quadratic equation, factor the left hand side of the equation into two linear factors.

Answers

Answer:

(x-6)(x-4) = 0

Step-by-step explanation:

Subtract 5 from both sides to make the equation equal to 0. You will get the equation x2-10x+24=0. Now think of two numbers that multiply to get 24 but add to get -10. These numbers are -6 and -4. The factors of x2 are x and x which multiply to get x2.  Now put two linear factors into parathesis to get (x-6)(x-4) = 0.

The local newspaper has letters to the editor for 40 people if this is the number represents 5% of all the newspaper readers how many readers does the newspaper have. fill in the blanks

Answers

40/5= 8  8 is 1% of the total people, 1% x 100 = 100%

8 x 100 = 800 people

The answer to this question would be: The newspaper has Eight hundred  readers.

Part = Percent x Whole

40 = 5% x 800

Do the equation above to make sure your correct( it is) and if it doesn't come back to 40 then your math is incorrect and you have the incorrect answer

A car leaves at 9 : 00 a.m. and drives at a constant speed. It is 20 miles from its starting point at 9 : 30 a.m. At what time will the car be 200 miles from its starting point?

PLSSSS HELP

Answers

Answer:

2:00 PM

Step-by-step explanation:

I figured out that the car is going 40 mph seeing as how it went 20 miles in 30 minutes.

I used this and found out how many hours it would take to get to 200 miles at this rate:

200/40 = 5

I divided 40 by 200 as 200 is the end goal and the car is going 40 mph.

The 5 is 5 hours, so I added 9 and 5 to get 14 which is 2:00 PM

Hope this helps!! :)

Janet has 3 cube-shaped boxes. Each box has a side length of 10 inches. What is the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes

Answers

Answer:anyone here watch anime

Step-by-step explanation:

EREN JEAGER

The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Side of each cube = 10 inches

Number of cubes =3

As we know The minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes will be the total surface area of all 3 boxes.

What is the total surface area of a cube?

The total surface area of a cube with side a is 6a².

So, the total surface area of a cube with a side of 10 inches will be 6*10² = 6*100 = 600 square feet.

So, the total surface area of 3 cubes with a side of 10 inches will be 600*3 = 1800 square inches.

As we know that 1 square inch = 0.00694444 square feet

So, 1800 square inches = 1800*0.00694444 = 12.5 square feet.

Therefore, the minimum amount of wrapping paper needed, in square feet, to wrap all 3 boxes is  12.5 square feet.

Answers

Answer:

NM = [tex]\sf \sqrt{70}[/tex]

Step-by-step explanation:

Let NM = y

If KL is twice the length of NM, then KL = 2y

Given:

KM = 20NO = 7

As ΔKLN ~ ΔNOM

   KL : KM = NO : NM

[tex]\sf \implies 2y : 20 = 7 : y[/tex]

[tex]\sf \implies \dfrac{2y}{20}=\dfrac{7}{y}[/tex]

[tex]\sf \implies 2y \cdot y=7 \cdot 20[/tex]

[tex]\sf \implies 2y^2=140[/tex]

[tex]\sf \implies y^2=70[/tex]

[tex]\sf \implies y=\sqrt{70}[/tex]

As NM = y, then NM = [tex]\sf \sqrt{70}[/tex]

Answer:

NM = [tex]\sqrt{70}[/tex]

Step-by-step explanation:

Δ NMO and Δ KML are similar ( by the AA postulate )

Then the ratios of corresponding sides are in proportion, that is

[tex]\frac{NM}{KM}[/tex] = [tex]\frac{NO}{KL}[/tex] ( substitute values, noting KL = 2NM )

[tex]\frac{KM}{29}[/tex] = [tex]\frac{7}{2NM}[/tex] ( cross- multiply )

2 NM² = 140 ( divide both sides by 2 )

NM² = 70 ( take the square root of both sides )

NM = [tex]\sqrt{70}[/tex]

For a given show, a theater charges $80 for a premium ticket and $30 for a regular ticket. If a total of n tickets were sold and p of them were premium tickets, what is the total amount, in dollars, from the sale of regular tickets and premium tickets?

Please explain the process.

Answers

Answer:

50p + 30n

Step-by-step explanation:

Cost of each premium ticket = $80.

Cost of each regular ticket = $30

Total tickets sold = n

We are told that p tickets were sold. Thus;

Total tickets sold is; p + (n - p)

Thus total amount generated is;

T = 80p + 30(n - p)

T = 50p + 30n
