Answer:

A) 3.6(1.85 + 2.30)

Step-by-step explanation:

Given that 3\frac{3}{5} pounds of grapes at $1.85/pound and 3\frac{3}{5} of red grapes at $2.30 per pound.

Given the mass of the different grapes is the same, the cost can be expressed as;

C_g=3\frac{3}{5}\times \$1.85\\\\C_r=3\frac{3}{5}\times\$2.30\\\\C_t=C_g+C_r\\\\=3\frac{3}{5}\times \$1.85+3\frac{3}{5}\times\$2.30\\\\=3\frac{3}{5}( \$1.85+\$2.30)\\\\=3.6(\$1.85+\$2.30)

Hence, the cost can be expressed as 3.6(1.85+2.30)

Help please urgent 25 point
uranmaximum [27]

Answer:

60

Step-by-step explanation:

b = the hypotenuse of a right angle triangle

a = the adjacent side.

R is being defined by the cosine

cos(R) = adjacent /  hypotenuse

adjacent = 16* sqrt(2)

hypotenuse = 32*sqrt(2)

Cos(R) = 16*sqrt(2) / 32*sqrt(2)      sqrt(2) cancels.

cos(R) = 1/2

R = cos-1(1/2)

R = 60 degrees.
