The width of a rectangle is 13 inchs more than 5 times the length. if x represents the length, write an algebraic expression in

rjkz [21]

perimeter is 2L+2W

problem states width = 5L+13

so plug that in for w:

P=2L+2(5L+13)

now simplify

P=2L+10L+26

P=12L+26

The measures of the angles of a triangle are in the extended ratio 4 : 5 : 6. What is the measure of the smallest angle?

ozzi

4x +5x +6x = 180
15x = 180
x = 180/15
x = 12
So smallest angle = 4*12 = 48 degrees

Lin opened a lemonade stand during the summer. She

AnnyKZ [126]

Answer:

59 cups ;

10 cups

Step-by-step explanation:

Given that he fitted model :

c = 2t - 89

Where, c = cups of lemonade sold ; t = high temperature

On a day when high temperature is 74 degrees ; cups of lemonade sold

Hence,

c = 2t - 89

c = 2(74) - 89

c = 148 - 89

c = 59 cups

Sunday is expected to be 5 degree warmer than on Saturday :

The number of cups sold on Sunday using the fitted model should be :

Difference in temperature between Saturday and Sunday multiplied by the slope value

Slope value from the model = 2

Temperature difference = 5

Difference in Number of cups :

2 * 5 = 10 cups

Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
