HELP I DONT KNOW THE ANSWER

Answer:

  3/4; 1/4, 1/4, 1/4

Step-by-step explanation:

The intent here is to let you demonstrate your understanding that multiplication by an integer is the same as repeated addition.

Your knowledge of fractions tells you ...

  \dfrac{1}{4}\times3=\dfrac{3}{4}

The factor of 3 means this is equivalent to adding 1/4 a total of 3 times:

  \dfrac{1}{4}\times3=\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}

OLEGan [10]

The correct answer is A.d* log_ba

Step-by-step explanation:

According to the power rule for logarithms, the logarithm of a power can be simplified by writing it as the product of the exponent multiplied by the logarithm of the base.

For example;

log_b(M^n)=nlog_bM

Hence in this case,

log_ba^d=d*log_ba

Answer:

Step-by-step explanation:

Remark

The measurement of the arc is 3Pi

that represents 108 / 360 of the circle.

Equation

108/350 2 * pi * R = 3* pi

Solution                            

Pi is on both sides of the equation. They both cancel.

108/360 = 0.3

0.3 * 2 * R = 3

0.6 * R = 3

R = 3/0.6

R = 5
