A quadrilateral has angles that measure 44°, 89°, and 127°. What is the measure of the fourth angle?

Answers

The sum of angles in a quadrilateral = 360 degrees.

Let the fourth angle be x:

Therefore:  44 + 89 + 127 + x = 360

260 + x = 360

x = 360 - 260

x = 100

x = 100°

Decorating your house for Christmas takes 106ft of lights. You use two lengths of lights,the short length of lights is 5 ft and the long length of lights is 11 ft. The total number of
strings of lights you use is 14. How many of each type of light do you have?

Answers

Answer:

  • 8 short and 6 long strings

Step-by-step explanation:

Let the number of lights are short = s and long = l.

According to question we have:

  • s + l = 14
  • 5s + 11l = 106

Subtract 5 times the first equation from the second one to solve for l:

  • 5s + 11l - 5s - 5l = 106 - 5*14
  • 6l = 36
  • l = 36/6
  • l = 6

Find s:

  • s = 14 - 6 = 8

Answer:

A good rule of thumb is 100 lights for every 1.5 feet of tree. However, if you love lights, you may want to double, or even triple, that amount.

Jayden’s new puppy weighed 11 1/4 pounds at 4 weeks old. At 16 weeks old, the puppy weighed 1 2/3 times more.How much did Jayden’s puppy weigh at 16 weeks old?

Answers

Answer:

18.75 or 18 3/4 lbs

Step-by-step explanation:

We just have to multiply 11 1/4 and 1 2/3 to get the product, 18.75 or 18 3/4.

First we have to translate our fractions into decimals:

11.25 (11 1/4) and 1.166667 (1 2/3)

multiply:

11.25 x 1.166667 = 18.75

convert back to fraction:

18 3/4
