What single decimal multiplier would you use to increase by 7% followed by a 9% increase?​

Answers

Answer:

[tex]Digit = 1.1663[/tex]

Step-by-step explanation:

Given

Increase by 7% followed by a 9% increase

Required

Represent by a single decimal

Represent 7% increment by x and 9% increment by y.

Increment by 7% is:

[tex]x = 1 + 7\%[/tex]

Express as decimal

[tex]x = 1 + 0.07[/tex]

[tex]x = 1.07[/tex]

Increment by 9% is:

[tex]y = 1 + 9\%[/tex]

Express as decimal

[tex]y = 1 + 0.09[/tex]

[tex]y = 1.09[/tex]

The single digit is:

[tex]Digit = x * y[/tex]

[tex]Digit = 1.07*1.09[/tex]

[tex]Digit = 1.1663[/tex]

Simplify if needed

Answers

Answer:

1/12

Step-by-step explanation:

Start by simplifying the fraction's signs:

[tex]-\frac{2}{3} - (- \frac{3}{4} ) = -\frac{2}{3} +\frac{3}{4}[/tex]

Now write both fractions as equivalent fraction with a common denominator of 12:

[tex]-\frac{2}{3} +\frac{3}{4} =-\frac{8}{12} +\frac{9}{12}=\frac{1}{12}[/tex]

If you need to add 5/6 to 5/12

again you need to write the fractions with a common denominator in this case also 12:

[tex]\frac{5}{6} +\frac{5}{12}= \frac{10}{12} +\frac{5}{12}=\frac{15}{12} = \frac{5}{4}[/tex]

in this last step we simplified a common factor of "3" in numerator and denominator to reduce the fraction to 5/4

The answer to this question is 1/12

I have this question on a homework and don't know how to do It ​

Area of a triangle  = 1/2 x length x height.

80 = 1/2 x (x+1) (2x-2)

Multiply both sides by 2:

160 = (x+1)(2x-2)

Expand the right side:

160 = 2x^2 -2

Add 2 to both sides:

162 = 2x^2

Divide both sides by 2:

81 = x^2

Take the square root of both sides:

x = 9

Now find the length of the s1des:

(x+1) = 9+1 = 10

2x-2 = 2(9) -2 = 18-2 =16

Exponent is defined as the method of expressing large numbers in terms of powers. That means, exponent refers to how many times a number multiplied by itself.

With the base 4 and exponent 3, we have

What is 0.36¯¯¯¯ expressed as a fraction in simplest form

Answers

Answer:

I think this is probably late, but the answer is 4/11.

Step-by-step explanation:

0.36363636363 is the first repeating fraction and 36.36363636 is the second repeating fraction, because you multiply it by 100.

When 0.3636363636363 is multiplied by 100, the decimal moves from in front of the number 36 and moves behind it. So the answer is now 36.36363636

You're suppose to subtract those two minus each other, the denominator

the fraction is technically 36/99, but simplified version is 4/11. So the answer is indeed 4/11.

Answers

Answer:

The total sale price that Gechina paid was $5,274.71.

Step-by-step explanation:

Given that Gechina Galvez shopped at a department store during the end-of-summer sale in which all luggage was marked down 35 percent, and she purchased a suitcase that regularly sells for $74.95, a garment bag that regularly sells for $8,000, and a tote bag that regularly sells for $39.99, in order to know the total sale price, the following calculation has to be made:

100 - 35 = 65

(8,000 + 74.95 + 39.99) x 0.65 = X

8,114.94 x 0.65 = X

5,274.71 = X

Therefore, the total sale price that Gechina paid was $5,274.71.
