The diameter of a quarter is 2.4 centimeters. the diameter of a dime is
1.8 centimeters. angelica places 100 quarters and 70 dimes side by side in a row.
(a) how long, in meters, is angelica’s row of coins? describe each step you took
to solve the problem.
(b) use estimation to explain how you know your answer is reasonable.
(c) how much money does angelica have? show two different ways to solve
the greates common factor (gcf) is: 2 x 2 x 11 = 44
m∠ghe = 117°
in the case of an equilateral trapezoid, the angles on the bases (parallel sides) are the same (congruent):
m∠gfe ≅ m∠hef = 63° and m∠fgh ≅ m∠ghe = ?
angles m∠fgh and m∠gfe are supplemental (comparative) angles and their sum is 180°
m∠fgh + m∠gfe = 180° => m∠fgh = 180° - m∠gfe = 180° - 63° = 117°
m∠fgh = 117°
as we know that:
m∠fgh ≅ m∠ghe = 117°
m∠ghe = 117°
god with !
hello from mrbilldoesmath!
27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
let f(t) - 9 sqrt(t) sin(t), then
y' = f(x^3) * d(x^3)/dx - f(sqrt(x)) * d(x^1/2)/dx
= (9 sqrt(x^3)sin(x^3)) * 3x^2 - (9 sqrt(x^1/2)sin(x^1/2)) * (1/2) x^-(1/2)
= 27 x^2 sqrt(x^3) sin(x^3) - 9/2 sqrt(x^1/2) sin(x^1/2)*x^(-1/2)
hope i didn't make a "bozo" error differentiating things!
1.8 centimeters. angel...
