what fraction is equivalnt to 3/4

Answer:

Rational

Step-by-step explanation:

Rational numbers:

Rational numbers are such numbers that can be expressed in the form p/q, where the value of q must not be equivalent to 0.

Irrational numbers:

These numbers cannot be expressed in the form p/q, where the value of q must not be equivalent to 0.                                                                                                                                          

[tex]\implies 2.89 = \dfrac{289}{100} \ \ \text{[In} \ \frac{\text{p}}{\text{q}} \ \text{form (\text{q}} \neq 0)]}[/tex]

Thus, 2.89 is a rational number.

Answer:

[tex]\sf 0.53\quad and \quad \dfrac{53}{100}[/tex]

Step-by-step explanation:

Convert the end points to decimals:

[tex]\textsf{5 tenths}=\dfrac{5}{10}=5 \div 10=0.5[/tex]

[tex]\textsf{6 tenths}=\dfrac{6}{10}=6\div 10=0.6[/tex]

If the number line has 9 tick marks between the endpoints, there will be 10 equal spaces (see attachment), so the tick marks denote hundredths.

The difference between 0.6 and 0.5 = 0.1

Divide this by 10:   0.1 ÷ 10 = 0.01

Therefore, each tick mark on the number line denotes hundredths and is 0.01 greater than the previous tick mark.

If Point A is labeled on the third mark after 5 tenths then:

A = 0.5 + 0.01 + 0.01 + 0.01 = 0.53

0.53 as a fraction:

[tex]\implies 0.53 = \dfrac{0.53}{1}=\dfrac{0.53 \times 100}{1 \times 100}=\dfrac{53}{100}[/tex]

Therefore, point A is:

[tex]\sf 0.53\quad and \quad \dfrac{53}{100}[/tex]

Answer: i need points

Step-by-step explanation:

Answer:

Step-by-step explanation:

By balancing horizontal and vertical forces, we find the cable tensions to be ...

  Ta = W·sin(b)/sin(a+b) . . . . . where W is the weight being held

  Tb = W·sin(a)/sin(a+b)

Where Ta is the tension in the cable that makes an angle of 'a' with respect to the vertical, and Tb is the tension in the cable that makes an angle of 'b' with respect to the vertical.

__

The given angles are with respect to the ceiling, so the angles with respect to the vertical will be their compmements.

  angle 'a' is 90° -18° = 72°

  angle 'b' is 90° -72° = 18°

  a+b = 72° +18° = 90°

  Ta = (400 lb)sin(18°)/sin(90°) = 123.607 lb

  Tb = (400 lb)sin(72°)/sin(90°) = 380.423 lb

_____

Additional comment

The nice expressions for cable tension come from the balance of forces.

  vertical: Ta·cos(a) +Tb·cos(b) = W

  horizontal: Ta·sin(a) = Tb·sin(b)

Solving the horizontal equation for Ta, we get ...

  Ta = Tb·sin(b)/sin(a)

Substituting into the vertical equaiton gives ...

  Tb·sin(b)cos(a)/sin(a) +Tb·cos(b) = W

Multiplying by sin(a) gives ...

  Tb(sin(b)cos(a) +sin(a)cos(b)) = W·sin(a)

Using the trig identity for the sine of the sum of angles, we can rewrite this in the form shown above:

  Tb = W·sin(a)/sin(a+b)

The problem is symmetrical with respect to 'a' and 'b', so the other tension is found by interchanging 'a' and 'b' in the equation:

  Ta = W·sin(b)/sin(a+b)

Answer:

2,355 cubic units

Step-by-step explanation:

We will see that the volume of the sphere is 2,355 cubic units.

How to get the volume of a sphere?

We know that for a sphere of radius R, the volume is given by:

Here we know that:

R = 10 units

pi = 3.14

Replacing that in the volume equation we get:

So the volume of the sphere is 2,355 cubic units.

Answer:

B. 2

Step-by-step explanation:

So when we are dealing with exponents identify the following terms

Base:  the number being multiplied by itself

Exponent: the number of times you multiply the base number by itself

So in this problem we would have to find what x is in order to find our exponents, you can do this by substiting each number for x and solving as  is

Answer:

1) C or B

2) J

3) C

4) J

Step-by-step explanation:

1) I am not sure but I think you start with the x so that is -5 then y which is 7 so y= 5/7x - 5 or y= 7/5x - 5

2) The graph always starts at the origin (0.0) that where the line should be put
3) 39 in + 78 in = 117 in

4)

2/3.5 = 0.57

4/7 = 0.57

Answer:

$36.00

Step-by-step explanation:

original cost= $45.00

discount= 20%

the sale price of the skateboard.

[tex]original \: price \times \frac{discount \%}{100} [/tex]

[tex] = 45.00 \times \frac{20}{100} [/tex]

[tex] = 45 \times 0.2[/tex]

[tex] = 9.00[/tex]

[tex]45 - 9[/tex]

[tex] = 36.00[/tex]

therefore, the sale price of the skateboard is $36.00

Answer: x = -6

Step-by-step explanation:

     The line of x = -6 will be parallel to the y-axis because it is a vertical line, and the y-axis runs vertically.

    I have graphed the line of x = -6 so you can see it and compare it with the y-axis. See attached.

Answer:

(a) $60

(b) $180

Step-by-step explanation:

Let the price of 1 table lamp be t.

Then the price of a fan is 3t.

2(3t) + 3t = 540

6t + 3t = 540

9t = 540

t = 60

A table lamp costs $60.

3($60) = $180

A fan costs $180.

Answer:

a) 70°

Step-by-step explanation:

∠3 = 110

∠5 = ∠1

∠1 = 180 - ∠3

∠1 = 180 - 110

∠ 1 = 70

∠5 = ∠1 (corresponding angles postulate)

∠5 = 70

Answer:

  D)  2

Step-by-step explanation:

When solving a system of equations using elimination, it often works well to start with them in a form that has all of the variables on the same side of the equal sign. Putting the second equation into standard form will accomplish that:

To eliminate one of the variables from the system, the equations are multiplied by numbers and combined (added or subtracted) so that the coefficient of one of the varibles becomes 0.

__

The coefficients of x are 3 and 2. If we are to eliminate x, we either need to multiply one equation by a rational number (2/3 or 3/2), or we need to multiply the two equations by two different numbers (2, 3).

The coefficients of y are -2 and 1. If we are to eliminate y, it is convenient to multiply the second equation by 2. This is probably the most convenient choice.

__

Multiplying the second equation by 2 and adding it to the first equation, we have ...

  (3x -2t) +2(2x +t) = (4) +2(5)

  7x = 14 . . . . . simplify; the y-variable is eliminated

  x = 2 . . . . . . divide by 7

Using the original second equation, we have ...

  2(2) -5 = -t = -1

  t = 1

So, the solution is (x, t) = (2, 1).
