Answer:

0.098

Step-by-step explanation:

It should be obvious that 0.098 is bigger than 0.046 and 0.059, so let's focus on 0.01

0.01 = 0.010 and again it should be obvious that it's smaller than 0.098

Answer:

B 17.5 ft

Step-by-step explanation:

tangent = opposite / adjacent

tan 35° = h / 25

multiply both sides by 25

h = 25 (tan 35°)

tan 35° = 0.70 (from your calculator)

h = 25 (0.70)

h = 17.51 ft.

Answer:6 17/18 hours

Step-by-step explanation:

We are informed that on Monday Katie spent 2 1/6 hours studying while onn Tuesday she spent another 4 7/9 hours studying.

The combined length of time she spent studying will be the addition of the numbers of hours spent studying on Monday and Tuesday. This will be:

= 2 1/6 + 4 7/9

= 2 3/18 + 4 14/18

= 6 17/18

She used a total of 6 17/18 hours studying

Question isn't well formatted :

If I have 48 cards and and gave 10 to my friend and I have 38 left. what fraction of original number of card do I have left.

Answer:

0.7917

Step-by-step explanation:

If I have 48 cards and and gave 10 to my friend and I have 38 left what what fractionbb be is my original number of cards

Given that :

Total number of cards = 48

Number given to friend = 10

Number of cards left = 48 - 10 = 38

Number of cards left / original number of cards

38 / 48

= 0.7917

Answer:

162

Step-by-step explanation:

step 1. our output value is 360

step 2. we represent the unknown value with x

step3. from step 1 above, 360= 100%

step 4. similarity, x=45%

step 5. this result in a pair of simple equations

360=100%(1)

x=45%(2)

step 6. by dividing equation 1 and 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have

360/x = 45/100

x=162

therefore, 45% of 360 is 162

Answer:

50º

Step-by-step explanation:

A triangles angles = 180º

Angle A = 40º

Angle C = 90º  (this is a right triangle)

40º + 90º = 130º

180º - 130 º = 50º

Answer:

x = 10, y = 12

Step-by-step explanation:

x = 10

2(6) = y

y = 12

Answer: 12.57 ft

Step-by-step explanation:

Circumference of circle with radius of 4ft.

= π * radius * 2

= 22/7 * 4 * 2

= 25.14 ft

Circumference of circle with radius of 6ft.

= 22/7 * 6 * 2

= 37.71 ft

Difference = 37.71 - 25.14

= 12.57 ft

Answer:

71.13

Step-by-step explanation:

The half area of a circle is A = 1/2 * pi*r^2 = 1/2 * pi * 3^2 or 9

The trapezoid is a rectangle and a triangle. Rectangle is 8*6 and the triangle is 6*(11 - 8) * 1/2

The total is 1/2 * pi * 9 + 8*6 + 6*(11 - 8) * 1/2 = 71.13

Answer:

x=27

Step-by-step explanation:

cos and sin are complementary angles. There theta or x add up to 90 degree. Using the formula.

cos x=sin y where x+y=90 let set up the equation.

[tex] \cos(2x + 9) = \sin(x) [/tex]

[tex]2x + 9 + x = 90[/tex]

[tex]3x + 9 = 90[/tex]

[tex]3x = 81[/tex]

[tex]x = 27[/tex]

To check our identity plug x in the top equation

[tex] \cos(2 \times 27 + 9)) = \sin(27) [/tex]

[tex] \cos(63) = \sin(27) [/tex]

they both equal about 0.45 so it is true.

x=27

Answer:

138

Step-by-step explanation:

Answer:

{-5/4, 8}

Step-by-step explanation:

We are given (4u + 5)(8 - u) = 0.  Solve for u by setting each of the factors (4u + 5) and (8 - u) equal to zero and solving each of the resulting equations:

4u + 5 = 0 leads to u = -5/4, and

8 - u = 0 leads to u = 8.

The solutions are {-5/4, 8}

Don Juan fue a la ferreteria a comprar una manguera para regar su jardín. Después de observar varias, eligió la que tiene la siguiente etiqueta. 83 pies, Diamtero interior 1/2 in. a) ¿Cuántos metros de longitud tiene la manguera que compró Don Juan? b) ¿Cuántos centímetros de diámetro interior tiene la manguera?

Responder:

25,30 m

1,27 cm

Explicación paso a paso:

Estamos obligados a convertir la longitud de la manguera de pies a metros y el diámetro de pulgadas a centímetros:

Longitud de la manguera = 83 pies

Recordar ;

1 pie = 0.3048 m

83 pies = (83 * 0.3048) = 25.2984 m

= 25,30 m

El diámetro de la manguera = 1/2 pulgadas

1 pulgada = 2,54 centímetros

1/2 pulgada = (1/2 * 2.54) cm

1/2 pulgada = 1,27 cm

Answer:

C

Step-by-step explanation:

Let's try it

Take 4 out of the given function.

4(x^2 + 3x )

Now there is an ex on either side of the plus sign that can come out. If 4 can come out because a 4 is on either side of the plus sign, so can an ex.

4x(x + 3)

What have you found?

4 is a factor

x is a factor

x + 3 is a factor

What about 3x. Well it won't work evenly and a factor must divide evenly into the given function.

Answer:

61% increase if the airlines held a 50$ baggage fee

Step-by-step explanation:

Answer:

The answer is 1. f(a) = –2a^2 – 5a + 4. If a = -3, then to find f(-3) we have to substitute a in the general formula. f(a) = –2a^2 – 5a + 4 = -2 * a^2 – 5 * a + 4. Substitute a with -3. f(-3) = –2 * (-3)^2 – 5 * (-3) + 4 = -2 * 9 - (-15) + 4 = -18 + 15 + 4 = 1

Step-by-step explanation:

The base of the triangle is 4.67 feet.

Given data:

To clarify, if a triangle with a base labeled b, a height of 6 feet, and an area of 14 square feet, the missing dimension can be determined as:

The formula to calculate the area of a triangle is:

Area = (base * height) / 2

Given that the area is 14 square feet and the height is 6 feet, rearrange the formula to solve for the base:

14 = (b * 6) / 2

Multiplying both sides of the equation by 2:

28 = b * 6

Dividing both sides of the equation by 6:

b = 28 / 6

Simplifying the fraction:

b = 14 / 3

Hence, the missing dimension, the base of the triangle, is 14/3 feet or approximately 4.67 feet.
