A Gardner wants to add 39 pounds of nutrient a and 16 pounds of nutrient b to her garden. Each bag of brand x provides 3 pounds
ehidna [41]

Answer:

5 bags of brand x and 6 bags of brand y.

Step-by-step explanation:

Nutrient requirement for the garden:

39 pounds of nutrient a and

16 pounds of nutrient b

Component of each bag of brand x:

3 pounds of nutrient a and 2 pounds of nutrient b

Therefore, 5 bags of brand x will contain 15 pounds of nutrient a and 10 pounds of nutrient b

Component of each bag of brand y:

4 pounds of nutrient a and 1 pound of nutrient b

Therefore, 6 bags of brand y will contain 24 pounds of nutrient a and 6 pounds of nutrient b

Altogether, she should buy 5 bags of brand x and 6 bags of brand y to meet the nutrient requirement of the garden

The circumference of a standard bowling ball is about 27 in. To the nearest unit, how many square inches is the surface area of
Sidana [21]
The surface area of a sphere is S=4 \pi  r^{2} where r is the radius;
The circumference is 2 \pi r=27 in so that r= \frac{27}{2 \pi }=4.5 in using this value we can evaluate the surface area of 1 ball as:
S=4 \pi r^{2} =4 \pi  (4.5)^{2} =254.3  in^{2}
For 100 ball you get: 100*254.3=25430  in^{2}

When Nabhitha goes bowling, her scores are normally distributed with a mean of 115
frutty [35]

Answer:

By the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232Step-by-step explanation:The Empirical Rule states that, for a normally distributed random variable:68% of the measures are within 1 standard deviation of the mean.95% of the measures are within 2 standard deviation of the mean.99.7% of the measures are within 3 standard deviations of the mean.In this problem, we have that:Mean = 190Standard deviation = 14Using the empirical rule, what percentage of the games that Aubree bowls does she score between 148 and 232?148 = 190 - 3*14So 148 is 3 standard deviations below the mean.232 = 190 + 3*14So 232 is 3 standard deviations above the meanBy the Empirical Rule, in 99.7% of the games that Aubree bowls she scores between 148 and 232

Could someone please explain to me how to determine the answer to this question?
dexar [7]

Concept: Solution of the given attachment is based on the addition of two vectors as given below.

Consider two vectors P and Q, then resultant of these two vectors is given as,

R = P + Q

To find the addition of G & H vectors. That is G + H =?

In the given figure;

Vector A = - Vector G because both are in opposite directions -----(i)

From the figure,

A + H = F --------------- using the given concept ---------(ii)

Now, shall replace the value of A from equation (i) in equation(ii)

- G + H = F

or, G + (- H) = - F

Since the vector addition of G & H is not equal to F.

Hence, the given statement G + H = F is False.
