Renaldo will write StartFraction 3 over 20 EndFraction as a decimal. Which of the following methods should he use? A:Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

B:Multiply the fraction by One-fifth to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

C:Multiply the fraction by StartFraction 33.3 over 33.3 EndFraction to get a numerator of 100 and then write the denominator as hundredths using a decimal point.

D:Multiply the fraction by 33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.

Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.

Step-by-step explanation:

Renaldo will write as a decimal.

We need to choose methods he should use.

To convert fraction into decimal we need to make denominator the multiple of 10

If we multiply 20 by 5 we get 100, so multiplying the given fraction by because we need to multiply both by numerator and denominator

So,

So, Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Option A is correct.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
