Answer:

9/4 yds fabric per 1 ft of ribbon

Step-by-step explanation:

3/4 yd fabric is required for every 2/3 ft of ribbon.  Let's put this info into an equation of ratios to figure out the number of yards of fabric required for every ONE ft of ribbon:

  3/4 yd fabric        2/3 ft ribbon

----------------------- = ---------------------

            x                    1 ft ribbon

Use cross mult. to solve this.  We obtain 3/4 = (2/3)x.

Mult. both sides by (3/2) yields (3/2)(3/4) = (3/2)(2/3)x = x.

This comes out to 9/4 yds fabric per 1 ft of ribbon.

The measure of two complementary angles are (4x + 3)° and (x + 4)°. What is the measure of the larger angle?
Aleksandr-060686 [28]

Answer:

69.4 degrees.

Step-by-step explanation:

Complementary angles add up to 90 degrees so we have the equation:

4x + 3 + x + 4 = 90

5x + 7 = 90

5x = 83

x = 16.6

The larger angle = 4x + 3

= 4(16.6) + 3

= 69.4 degrees (answer).

Answer:

0.53

Step-by-step explanation:

0.533

Decimal places go 10ths, 100ths, 1000ths, and so on. The nearest hundred therefore, is the first 3. Looking at the next digit, which is 3, because it's less than 4, we know we have to round down, which makes the answer 0.53

The graph of g is the graph of f translated horizontally 3 units to the left. If f(x) = 2x + 1 what is an equation for the funct
mart [117]

Answer: g(x) = 2(x + 3) + 1

Step-by-step explanation:

When we have an horizontal translation of A units (A is a positive real number) to the right, we write this as:

g(x) = f(x - A)

If the translation is to the left, then we have:

g(x) = f(x + A).

In this case, we have a translation to the left, and A = 3, then:

g(x) = f(x + 3)

And we know that:

f(x) = 2x + 1

g(x) = f(x + 3) = 2*(x + 3) + 1 = 2x + 6 + 1 = 2x + 7

g(x) = 2x + 7

Convert 81/4 to a decimal
Tomtit [17]
Hello.

81/4 as a decmail would be 

20.25

To convert this simple fraction to a decimal, just divide the numerator (81) by the denominator (4): 81 ÷ 4 = 20.25. So,

81/4 = 20.25

Rounded values:

<span><span>81/4 = 20 rounded to the nearest integer</span><span>81/4 = 20.3 rounded to 1 decimal place.

Have  a nice day</span></span>
