180*5/6 = 150

Answer:

step by step below

Step-by-step explanation:

14. y = x²+4x+1

    y=x+1

x+1 = x²+4x+1

x²+3x=0        x(X+3)=0

x=0 or x=-3

18. y=x²-3x-20

y=-x-5

-x-5 = x²-3x-20         x²-2x-15 = 0      (x-5)(x+3) = 0

x=5 or x=-3

20. y=x²+5x+1

y=x²+2x+1

x²+2x+1 = x²+5x+1            3x = 0

x = 0

22. y=-x²-3x-2

y=x²+3x+2

x²+3x+2 = -x²-3x-2        2x²+6x+4 = 0    2(x²+3x+2) = 2 (x+1)(x+2) = 0

x = -1 or x = -2

Answer:

x² + 4x + 3

Step-by-step explanation:

Dividing by (x - 5) then use h = 5 as divisor

5 | 1    - 1    - 17    - 15

    ↓     5     20     15

   -------------------------------

     1     4      3       0 ← remainder = 0

quotient = x² + 4x + 3

[tex]x^{2} +4x+3[/tex] is the quotient when [tex]x^{3} - x^{2} -17x-15[/tex] is solved using synthetic division.

Synthetic division is a simplified method for dividing a polynomial by another polynomial of the first degree by writing down only the coefficients of the several powers of the variable and changing the sign of the constant term in the divisor so as to replace the usual subtractions by additions.

Synthetic division of the given question-

5    |     1        -1        -17        -15

Step-by-step explanation:

Answer:

Principal in account A = $200

Principal in account B = $600

Account B earned more interest in the first month.

Step-by-step explanation:

Given two accounts:

Account A:

Time = 9 months = [tex]\frac{9}{12}[/tex] years

Interest rate = 3.8%

Interest earned = $5.70

Account B:

Time = 27 months = [tex]\frac{27}{12}[/tex] years

Interest rate = 2.4%

Interest earned = $32.40

To find:

Principal in each account.

Most interest earned in the first month?

Solution:

First of all, let us have a look at the formula for Simple Interest.

[tex]SI = \dfrac{P\times R\times T}{100}[/tex]

Putting the values for Account A and finding the value of Principal:

[tex]5.70 = \dfrac{P_A \times 3.8\times 9}{100\times 12}\\\Rightarrow P_A = \dfrac{570\times 12}{3.8\times 9}\\\Rightarrow P_A=\$200[/tex]

Now, Putting the values for Account B and finding the value of Principal:

[tex]32.40 = \dfrac{P_B \times 2.4\times 27}{100\times 12}\\\Rightarrow P_B = \dfrac{3240\times 12}{2.4\times 27}\\\Rightarrow P_B=\$600[/tex]

Interest earned in one month i.e. [tex]\frac{1}{12}[/tex] years:

Account A:

[tex]SI_A = \dfrac{200\times 3.8\times 1}{100\times 12}\\\Rightarrow SI_A = \$0.63[/tex]

[tex]SI_B = \dfrac{600\times 2.4\times 1}{100\times 12}\\\Rightarrow SI_B = \$1.2[/tex]

Account B earned more interest in the first month.

Therefore, the answers are:

Principal in account A = $200

Principal in account B = $600

Account B earned more interest in the first month.

Answer:

100°

Step-by-step explanation:

A triangle is a polygon shape with three sides. Triangles are of different types such as obtuse, scalene, equilateral, isosceles etc.

In triangle ABC:

70° + 50° + ∠C = 180° (sum of angles in a triangle)

120 + ∠C = 180

∠C = 180 - 120

∠C = 60°

Since ∠C is bisected into ∠ACD and ∠BCD, hence:

∠ACD = ∠BCD = ∠C / 2

∠ACD = ∠BCD = 60 / 2

∠ACD = ∠BCD = 30°

In triangle ACD:

∠A + ∠ACD + ∠ADC = 180° (sum of angles in a triangle)

50 + 30 + ∠ADC = 180

∠ADC + 80 = 180

∠ADC = 100°

Answer: this questions kind of confusing, but my guess is:

10x5=50 Becuase that's the same thing as saying 50/10 =5

Step-by-step explanation:

Answer:

Option A

Step-by-step explanation:

From the last triangle given in the picture,

x° = 45° + 85° [By the definition of exterior angle of a triangle]

x = 130°

Another way to get the value of x,

By triangle sum theorem,

45° + 85° + y° = 180°

y° = 180° - 130°

y = 50°

And (x° + y°) = 180° [linear pair of angles]

x + 50 = 180

x = 130°

Therefore, x = 130° because 180 - (45 + 85) = 50 and 180 - 50 = 130

Option A is the answer.

Answer:

There were 200 children and 400 adults in the auditorium.

Step-by-step explanation:

Given that there were a total of 600 peoples in the event.

Let there were n children in the event.

So, the number of an adult in the event = 600-n

As the admission price for one child = 15 pesos

and the admission price for one adult = 25 pesos.

So, total admission price = 15n+25(600-n)

As total money raised = 13000 pesos

So, 15n+25(600-n)=13000

15n+15000-25n=13000

10n=15000-13000=2000

n=2000/10=200

Therefore, number of children = 200

and the number of adults = 600-200=400.

Hence, there were 200 children and 400 adults in the auditorium.

Answer:

{0.99, 5.01, 5.25, 6.79, 6.99, 7.50, 7.51}   second option

Step-by-step explanation:

You can see from the histogram that there is

- one value = 0.99  that is from 0 to  2 dollars and 50 cents

- no values between 2 dollars and 51 cents and 5 dollars

- 5 values between  5 dollars and 1 cent to 7 dollars and 50 cents

-1 value between  7 dollars and 51 cents to 10 dollars

All the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.

Hence, The option C is the correct option which is,

{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}

Given-

Histogram titled number of Items Sold with Price Range on the x axis.

Histogram titled number of Items Sold on the y axis.

The range of bar 1 is 0 to 2 dollars and 50 cents and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 1 is 1 to 2.5 dollar.

The range of Bar 2 is 2 dollars and 51 cents to 5 dollars and has a height of 0. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 2 is 2.51 to 5 dollar.

The range of bar 3 is 5 dollars and 1 cent to 7 dollars and 50 cents and has a height of 5. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 3 is 0.01 to 7.5 dollar.

The range of bar 4 is 7 dollars and 51 cents to 10 dollars and has a height of 1. As 1 dollar has 100 cents hence 50 cent will be equal to the 0.50 dollar. Thus the range of bar 4 is 7.51 to 10 dollar.

In all the four bars the value of dollar fall between the range of 0 dollar to the 10 dollar. This condition satisfy only by the option C.

Hence, The option C is the correct option which is,

{0.75, 2.50, 7.50,7.50,7.50,7.50,10.00}

Answer:

b = 16.5

Step-by-step explanation:

Given

[tex]\frac{9}{11}[/tex] = [tex]\frac{13.5}{b}[/tex] ( cross- multiply )

9b = 148.5 ( divide both sides by 9 )

b = 16.5

Answer:

16.5

Step-by-step explanation:

we want to get b in the numerator and we want to get rid of the fractions so we multiply both sides by 11*b to get

9b=13.5*11

9b=148.5

divide both sides by 9 to get b by itself to get

b=16.5

Answer:

The speed of the truck is 1,200 miles.

Step-by-step explanation:

Car = 10 MILES PER HOUT FASTER THAN THE TRUCK.

Truck = X times 10

X = 120 MILES times 10

120 times 10= 1,200, BECAUSE IF YOU TAKE THE "1" FROM "10" IT'LL BE "1" FROM THE 10, TIMES 120 MILES WHICH = 120. NOW TAKE THE "0" FROM THE 10 AND ADD *0* AT THE END OF THE ANSWER YOU GOT WHICH WAS "120." THEN YOUR ANSWER WILL BE 1,200 IF YOU ADD THE "0" AT THE END.
