Round it to the nearest tenth so that would be 3.5

Area of triangle = 1/2 base x height

15.588 = 1/2 * base x 5.196

15.588 = base x 2.598

base = 15.588 / 2.598 = 6

 equi center of triangle = 1/3*5.196 = 1.732

radius of circle = Sqrt(1.732^2 + 3^2) =

 sqrt (2.999824 +9) =

sqrt(11.999824) = 3.464

rounded to nearest tenth = 3.5 inches

It's 26×10×10×10 because there are 26 possibilities (a-z) for the first letter and 10 possibilities (0-9) for each number. That makes the answer 26,000.

600 sixth-graders were surveyed.

Step-by-step explanation:

Step 1; Assume x is the total number of sixth-graders that were surveyed. According to the given circle graph, 5% of the sixth-graders that were surveyed have birds as their pets. If x is the total number of sixth-graders surveyed then 5% of x equals 30. So

5% of x = 30.

5% equals \frac{5}{100} = 0.05, so 5% = 0.05.

Step 2; If 0.05 x = 30, we can solve by keeping the unknown value on one side and keeping all the known values on one side.

x = \frac{30}{0.05} = 600.

So 600 sixth-graders were surveyed.

2) Ruth borrows $440 at 0.6% simple interest per month. When
MA_775_DIABLO [31]

Answer:

$10.56

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 0.6%/100 = 0.006 per year,

then, solving our equation

I = 440 × 0.006 × 4 = 10.56

I = $ 10.56

The simple interest accumulated

on a principal of $ 440.00

at a rate of 0.6% per year

for 4 years is $ 10.56.

For the function f(t)+Pe^rt, if P = 8 and r = 0.08, then what is the value of f(8) to the nearest tenth?
Bogdan [553]
F(t) = P.e^(r.t) [ and not as you wrote it  f(t)+Pe^rt]
plug in:

f(t) = 8.e^(0.08t) (where e = 2.718 and t=8 given, f(8))
f(8) = 8.(2.718)^(0.08*8) = 21.74^(0.64)

f(8) = 7.17
