How many 3/8’s are in 3

Mathematics

Answer: 8 times

Step-by-step explanation:

Youre essentially doing 3 divided by 3/8.

3 is equivalent to 3/1. And when you divide fractions, you have to multiply by the reciprocal. the reciprocal of 3/8 is 8/3.

\frac{3}{1} *\frac{8}{3} = \frac{24}{3} = 8

Answer:

8

Step-by-step explanation:

\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:+\:\:\frac{3}{8}\:

\frac{3}{8} \times 8

=3

We can also use algebra.

\frac{3}{8} \times x=3

x=3 \div \frac{3}{8}

x=8

Law Incorporation [45]

Answer:

y-1 = 5/3(x-3)

Choice C

Step-by-step explanation:

slope = (y2-y1)/(x2-x1)

(3,1) (6,6)

m = (6-1)/(6-3)

m = (5/3)

the point slope form of a line is given by

y-y1 = m(x-x1)

You have point (3,1)

y-1 = 5/3(x-3)

Choice C

Which is equivalent to sin-1(–0.4)? Round your answer to the nearest hundredth of a radian.
strojnjashka [21]

Answer:

-0.41 radians

Step-by-step explanation

(Credit goes to calculista)

let

A---> the angle

if sin A=-0.4

then 

A=sin-1(-0.4)

using a calculator

A=-23.578°----> the angle A belong to the IV quadrant

convert to radians

if pi radians--]----> 180°

x--------> -23.578°

x=-23.578*pi/180----> x=-0.41 radians

Find the value of x and y​
Svetllana [295]

Answer:

x = 1

y = -3

Step-by-step explanation:

cos(pi) = -1

so many ways :

sqrt(0.5/2) = sqrt(0.5/2 × 8/8) = sqrt(4/16)

= sqrt(0.5/2 × 18/18) = sqrt(9/36)

= sqrt(1/4) = 1/2

"nicest" approach (all integers) :

3x² = sqrt(9)

3x² = 3

x² = 3/3 = 1

x = 1

2y = sqrt(36)

2y = 6

y = 6/2 = 3

one of them has to be negative (because cos(pi) = -1), so it has to be y, because 3x² cannot be negative with real numbers.

so, y = -3

-1 × 3×1²/(2×-3) = sqrt(0.5/2) = 1/2

-1 × 3/-6 = 1/2

3/6 = 1/2

1/2 = 1/2

correct
