Answer:

Here the error is 

 $\pi {r}^{2}$ 

It should have been ,

 $2\pi {r}^{2}$ 

Step-by-step explanation:

Corrected formula:

 $2\pi {r}^{2} + 2\pi rh$ 

 $= 2\pi ({5}^{2}) + 2\pi(5)(10.6)$ 

 $= 50\pi + 106\pi$ 

 $= 156\pi$ 

 $= 489.84 {yd}^{2}$ 

 $approx . \: 489.8 {yd}^{2} (ans)$

The surface area of an oil spill gets 131% larger every day, represented by the function s(x) = (1.31)x − 1. On the first day, i

scoray [572]

Answer:

The correct option is B.

Step-by-step explanation:

It is given that the surface area of an oil spill gets 131% larger every day, represented by the function

Where x is number of days.

On the first day, it covered an area of 21 square meters. It means the initial area is 21 square meters.

The function is defined as

Where is initial value and b is growth factor.

It means the function of new area is the product of initial area and increasing area function. The required function is

Therefore option B is correct.

Using partial quotients what is the answer to 4÷92

Anna11 [10]

Well, you could easily type that into a calculator, but the answer would be 0.04347826, but when you say it as an answer you say the answer up to the hundredths place, which would be 0.043. =)

Q..3/4 of a piece of metal has a mass on 15 kg. What is the mass of 2/5 of a piece of metal ?

Margarita [4]

Answer

8kg

Explanation

3/4--------15

2/5-------x

cross multiplying

3/4×X = 2/5×15

3X/4 = 30/5

3X/4 = 6

cross multiplying

3X = 4×6

3X = 24

dividing bothsides by 3

3X /3 = 24/3

X = 8

therefore, the answer is 8 kg

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation is 5.5 days. One length of

Alenkinab [10]

Answer:

The statement that best interprets the z-score is;

D. The length of the gestation period was shorter than the mean length of gestation period by 1.7 standard deviations

Step-by-step explanation:

The given parameters are;

The length of the gestation period of the cattle breed = 284 days

The standard deviation = 5.5 days

The z-score of one length of gestation period was z = -1.70

The formula for finding the z-score, z is presented as follows

$Z=\dfrac{x-\mu }{\sigma }$

Where;

x = The observed value for the gestation period

μ = The sample mean length for the gestation period = 284

σ = The gestation period standard deviation = 5.5

When Z = -1.70, we have;

$-1.70 =\dfrac{x-\mu }{\sigma }$

∴ x - μ = -1.7 × σ

∴ x is shorter than μ by 1.7×σ

Therefore, the length of the gestation period, x, was shorter than the mean length of gestation period, μ, by 1.7 standard deviations, σ.
