Step-by-step explanation:

[tex] \sqrt[3]{49} = 3.65930571002 \approx3.66 \\ \\ so \: \sqrt[3]{49} should \: lie \: at \: 3.6 \: which \: \\ fall \: between \: 3 \: and \: 4.[/tex]

Actually Lin did a mistake, she obtained square root and not cube root.

Answer with Explanation:

[tex]3\sqrt{49}[/tex] should be placed in-between 3 and 4 on the number line (a little bit approaching number 4). The cube root of 49 is 6.66. Therefore, it shouldn't be placed on number 7.

Lin thought that she was asked to get the square root of 49, which looks like this: [tex]\sqrt{49}[/tex]. Probably, she missed the number 3. It was actually asking for the cube root of 49. This is also the reason why she placed the dot on the number 7 because the square root of 49 is 7.

Answer:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Step-by-step explanation:

Given the expression

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

Let us solve for h

[tex]S=\pi \:r\left(h+k\right)\:[/tex]

Flip the equation

[tex]\pi r\left(h+k\right)\:=\:S[/tex]

Apply distributive law: [tex]a\left(b+c\right)=ab+ac[/tex]

[tex]\pi hr+\pi kr=S[/tex]

Add -πkr to both sides

[tex]\pi hr+\pi kr+\left(-\pi kr\right)=S+\left(-\pi kr\right)[/tex]

[tex]\pi hr\:=\:-\pi kr\:+\:S[/tex]

Divide both sides by πr

[tex]\pi hr\:/\:\pi r\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Therefore, we conclude that:

[tex]h\:=\:\:\frac{-\pi \:kr\:+\:S}{\pi \:r}[/tex]

Answer:

45 degrees

Step-by-step explanation:

AOB = 140°

and an the angle bisector(OC) is a line which will divide AOB into 2 equal angles

which is 140÷2= 70

and if AOD = 25 then COD= 70-25

= 45 degrees

I NEED HELP WITH MATH HOMEWORK PLEASE.

Answers

Answer:

Step-by-step explanation:

we know A + B + C = 180 for a triangle

isosceles have the same angles on the base sides

so our equation can be rewritten with that

A + A + C = 180

2A+C=180

so we are also told that A is 9 less than 4 times the vertex .. vertex is the point or top... in this case.. or C

A= 4C-9

now plug it in

2(4*C-9) + C =180

8C-18+C=180

9C-18=180

9C=198

C = 22

Answers

Answer:

8x^2+34x+35

Step-by-step explanation:

My head knows

Step-by-step explanation:

(4x+7)(2x+5)

We would have to multiply each term in the first bracket by the term in the second bracket.

4x(2x+5)+7(2x+5)

So now we multiply 4x by 2x and 5

8x+10x

8x+10x+7(2x+5)

And then we multiply 7 by the 2x and the 5

14x+35

8x+10x+14x+35

So now we proceed to add since like terms have already been combined

Question 11 Batches of a chemical contain random amounts of lead with a mean value of 6.0 mg and a standard deviation of 2.0 mg. If 50 batches are prepared, the probability that their average amount of lead is greater than 6.5 mg is:

Answers

Answer:

0.0384

Step-by-step explanation:

Given that:

Mean (m) = 6.0

Standard deviation (s) = 2.0

Sample size (n) = 50

Probability that average amount is greater than 6.5

P(x > 6.5)

Obtain the Zscore using the relation :

Zscore = (x - m) / (s / sqrt(n))

Zscore = (6.5 - 6.0) / (2 / sqrt(50))

Zscore = 0.5 / 0.2828427

Zscore = 1.7677

Zscore = 1.77

P(Z > 1.77) = 1 - P(Z < 1.77)

P(Z > 1.77) = 1 - 0.9616

P(Z > 1.77) = 0.0384

Answer:

4.2%

Step-by-step explanation:

n=50, X=6.0, δ=2.0

Z=[tex]\frac{6.5-6.0}{2.0}[/tex] = 0.25

F(Z)= 4.2% based on the chart in the FE Handbook

Which is equivalent to (2x^2y)(8x^3y^3)?

Answers

4y =88 is your answer

Answer: A

Step-by-step explanation: In order to answer this you need to understand the rules of exponents. Whenever you multiply two terms with the same base or variable you add the powers together. For example, 4x*2x = 8x^2 or x^4*x^2 = x^6. Any term with a negative exponent is equivalent to its reciprocal. For example x^-2 = 1/x^2.

Knowing this we expand this equation by multiplying. (2x^-2y) * (8x^-3y^-3) = 16x^-5y^-2. We now move the variables with negative exponents to the bottom. Giving us 16/(x^5y^2).
