A collection of stamps consists of 22¢ stamps and 40¢ stamps. The number of 22¢ stamps is three more than four times the number of 40¢ stamps. The total value of the stamps is $8.34. Find the number of 22¢ stamps in the collection

Answers

Answer 1

Answer:

27

Step-by-step explanation:

Let :

Number of 40¢ = x

Number of 22¢ = 4x + 3

Total stamp value = $8.34 = (8.34 * 100) = 834¢

40¢x + 22¢(4x + 3) = 834¢

40x + 88x + 66 = 834

128x = 834 - 66

128x = 768

x = 768 / 128

x = 6

Number of 22¢ stamp:

4(6) + 3 = 24 + 3 = 27

"La suma de la medida de los ángulos interiores de cualquier triángulo, es igual a dos triángulos rectos, o sea a 180°."

Answers

Answer:

Efectivamente, la suma de la medida de los ángulos internos de cualquier figura triangular es igual a 180º. Ahora bien, la oración posee un error de redacción, pues tanto los triángulos rectos como los equiláteros o los isósceles poseen dicha característica, es decir, no es únicamente una característica de los triángulos rectos. Además, la suma de los ángulos interiores de dos triángulos rectos sería igual a 360º, no a 180º.

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.

Answers

Answer:

13.96

Step-by-step explanation:

length of an arc = theta/360 * 2πr

Given

m<HJK = 50

HJ = 16units

Required

length of arc HK

arc HK = 50/360 * 2(3.14)(16)

arc HK = 5/36 * 100.48

arc HK = 502.4/36

arcHK = 13.96

hence the length of arcHK to nearest hundredth is 13.96

X^2-3x=7/4
Solve by completing the square

Answers

Answer:

Step-by-step explanation:

X^2-3x=7/4 should first be rewritten in standard form, which here would be:

x^2 - 3x - 7/4 = 0.

1.  Identify the coefficient of the x term and take half of that number:

    -3/2

2. square this result:  (-3/2)^2 = 9/4

3.  add this last result, 9/4, between the -3x term and the -7/4 term, and then      subtract it as shown:

     x^2 - 3x + 9/4 - 9/4 - 7/4 = 0

4.  Rewriting the first 3 terms as the square of a binomial, we get:

    (x - 3/2)^2  -  16/4 = 0, or    (x - 3/2)^2  =  16/4

5.  Take the square root of both sides, obtaining:

     x - 3/2 = ±√4/2 or ±√2

6.  Write out the two roots:  x = 3/2 + √2

     and                                   x = 3/2 - √2

Henri buys 126 inches of a fabric that costs $12 for each yard. How much dos Henri pay for the fabric

Answers

1 yard = 36 inches

126 inches is:

= 126/32

Every two out of three kids sang at the talent show. What percent of the kids did not sing at the talent show? (round)

Answers

66.7 %
convert to decimal the multiply by 100

33.3% do not sing in the talent show.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of kids = 3

Number of kids who sang = 2

The number of kids who do not sing.

= 3 - 2

= 1

The percentage of kids who do not sing.

= 1/3 x 100

= 33.33%

Thus,

33.3% do not sing in the talent show.

Find the exact values of csc and sec

Answers

Answer:

cosec theta = 5/4

sec theta = 5/3

Step-by-step explanation:

Given that;

cot θ = 3/4

1/tanθ = 3/4

tanθ = 4/3

since tanθ = opp/adj

opp = 4

adj = 3

hyp^2 = 4^2 + 3^2

hyp^2 = 16+9

hyp^2 = 25

hyp = √25

hyp = 5

sin theta= opp/hyp

sin theta = 4/5

cosec theta = 1/sin theta

cosec theta = 1/(4/5)

cosec theta = 5/4

Get sec theta;

sec theta = 1/costheta

sec theta = 1/(3/5)

sec theta = 5/3

Answer:

9

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Given y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 9 when x = - 3

9 = - 3k ( divide both sides by - 3 )

- 3 = k

y = - 3x ← equation of variation

When y = - 27 , then

- 27 = - 3x ( divide both sides by - 3 )

9 = x
