Answer:

Step-by-step explanation:

the sum of all angles in a quadrilateral must be 360º

y+88+25+35 = 360

y = 360=88-25-35

y = 212º

the sum of all angles in an octagon must be 1080º

45+45+140+140+6y = 1080

6y = 1080-90-280

6y = 710

y = 710/6

y=~ 118,3º

jill is making a long cape she needs 4 1/3 yards of blue fabric for the outside of the cape she needs 3 2/3 yards of purple fabric for the lining of the cape

Answers

Answer:

Jill needs 8 yards of fabric to make a cape.

Step-by-step explanation:

Givens

Jill needs 4 1/3 yards of blue fabric for the outside of teh cape.
Also she needs 3 2/3 yards of purple fabric for the lining.

In order to know the total number of yards Jill needs to make a cape, we first need to transform each mixed number into fraction. We do that multiplying the whole part with the denominator and then adding it to the numerator, as follows

$4(1)/(3)=(13)/(3) \n3(2)/(3)=(11)/(3)$

Then, we sum both fractions

$(13)/(3) +(11)/(3)=(13+11)/(3)=(24)/(3) =8$

Therefore, Jill needs 8 yards of fabric to make a cape.

Hey there, just subtract 4 1/3 from 3 2/3 to get your answer. 4 1/3=13/3 and 3 2/3=11/3, 13*3-11*3/3*3=39-33/9=6/9, 6/9 simplified is 2/3

Mr. López teaches his classes how to make maraca instruments by filling plastic eggshells with dried beans Mr. López uses the equation p= 0.75n to find the number of pounds, p, of beans needed for “n” classes.What is the constant of proportionality between p and n?

Pleaseee I need it
Thank you

Answers

The constant of proportionality between p (pounds of beans) and n (number of classes) in the equation p = 0.75n is 0.75. In this equation, 0.75 represents the ratio of the number of pounds of beans (p) to the number of classes (n). It tells you that for each class, 0.75 pounds of beans are needed, making it the constant of proportionality.
