Mathematics
1 answer:
mote1985 [20]3 years ago
6 0

Answer:

r = 5.58

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

97.9 = 3.14 r^2

Divide each side by 3.14

97.9/3.14 =3.14 /31.4 r^2

31.17834395 = r^2

Take the square root of each side

sqrt(31.17834395) = sqrt(r^2)

5.583757153 = r

What is the best approximation for the perimeter of a semicircle with a dimeter of 12cm?
taurus [48]
Answer is choice B: the circumference of a circle is the same as perimeter and is defined by πd (or pi times diameter) We can cut this in half because we are working with a semicircle: so we have 6π which approximates to the value in answer when using 3.14 for pi Woops: forgot to add the diameter of 12 so we would have 30.84

Ray bought a shirt on sale for $18.00. The original price was $24.00. What percent was the discount?
Sunny_sXe [5.5K]

Answer:

The discount would be 25%

Step-by-step explanation:

24 and 18 are both divisible by 6

24 is just 4×6

18 is just 3×6

This means that 18/24 is the same as 3/4

We calculate the discount by subtracting the percentage of the sale price from the original price.

3/4 is the same as 75% of 100% meaning the discount percentage is 100-75, which gives us 25%

The parents of three children, ages 1, 3, and 6, wish to set up a trust fund that will pay X to each child upon attainment of ag
ehidna [41]

Answer:

The equation of <em>Z</em> is: Z=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})

Step-by-step explanation:

  • The first child is of age 1 year.

        Then the amount invested for the 1-year old is: Xv^{17}+Yv^{20}

  • The second child is of age 3 years.

        Then the amount invested for the 3-year old is: Xv^{15}+Yv^{18}

  • The third child is of age 6 years.

        Then the amount invested for the 6-year old is: Xv^{12}+Yv^{15}

The one-time investment will be:

Z=Xv^{17}+Yv^{20}+Xv^{15}+Yv^{18}+Xv^{12}+Yv^{15}\\=X(v^{17}+v^{15}+v^{12})+Y(v^{20}+v^{18}+v^{15})

-Dominant- [34]

Answer:

98 degrees

Step-by-step explanation:

We know that H is the same as G because the sides are marked equal.

41 + 41 = 82

In a triangle the measure of degrees in total is 180.

180 - 82 = 98
