Answer:
Yes she has enough walnuts for her two recipes
Step-by-step explanation:
Total number of walnuts that Marni has = 11 ounces
She has two receipe
First recipe = 6 ounces
Second recipe = 1/4 pounds
Hence,
To find out if she has enough:.we add up the number of ounces from both recipes
The second recipe is in pounds hence, we convert to ounces.
1 pound = 16 ounces
1/4 pound =
Cross Multiply
= 1/4 pounds × 16 ounces/1 pound
= 4 ounces
Hence, we can add up now
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
Since both recipes would require a total of 10 ounces of walnuts and Marin has 11 ounces, we can conclude that Marin has enough ounces of walnuts for her two recipes.
Answer:
14.4 ft
Step-by-step explanation:
The triangles formed by both ladders are similar to each other. Therefore, each corresponding sides will be proportional.
Thus, x + 8 would represent how far up the 10-foot ladder reaches the wall.
Therefore:
18/10 = (x + 8)/8
9/5 = (x + 8)/8
Cross multiply
9*8 = 5(x + 8)
72 = 5x + 40
72 - 40 = 5x
32 = 5x
Divide both sides by 5
32/5 = x
x = 6.4
The 10-foot ladder would be, 6.4 + 8 = 14.4 ft far up the wall.
Answer:
6 ounces
Step-by-step explanation:
this one is mainly elimination. 3.8 and 4.9 cant be because they're too close to the mean. and 7.1 is too far. you can also use z-score. the z score of .975 is 1.96 we can plug that into out formula so
1.96=(x-3.8)/1.1
multiply both sides by 1.1 and then add 3.8
you can also use scientific calculator.
second vars, 3, the area is your percent so .975, the u is mean so 3.8, the o is standard deviation so 1.1
