Answer:

Step-by-step explanation:

p(x) = r(x) * s(x)

= (x + 5) *(-7) {Use distributive property}

= x * -7 + 5 * -7

= - 7x - 35

1/7 (x-3) = 5/7 ? solve for x.

yuradex [85]

1/7 (x - 3) = 5/7
1/7x - 3/7 = 5/7
1/7x - 3/7 + 3/7 = 5/7 + 3/7
1/7x = 8/7
1/7x(7) = 8/7(7)
X = 56/7

Use trigonometry to find the value of x in the picture above.

bagirrra123 [75]

sin(48°) = x / 1200ft. Multiply each side by 1200ft.

1200ft × sin(48°) = x.

x = 891.77 ft.

PLEASE HELP I GIVE ALL MY POINTS PLZZZZ!!!!! Select the correct answer. Vector u has its initial point at (1, -12) and its termi

dimulka [17.4K]

Answer:

Vector u has u_x = (5 - 15) = -10, and u_y = -4 - 22 = -26, and its component form would be u = -10i - 26j.

If vector v is in the opposite direction: 10i + 26j

And if it is double in magnitude: v = 20i + 52j

Hope this helps you! Ask me anything if yu have any quistions!

A truck is being filled with cube-shaped packages that have side lengths of 1/4 foot. The part of the truck that is being filled

n200080 [17]

Answer:

24000 pieces.

Step-by-step explanation:

Given:

Side lengths of cube = $\frac{1}{4} \ foot$

The part of the truck that is being filled is in the shape of a rectangular prism with dimensions of 8 ft x 6 1/4 ft x 7 1/2 ft.

Question asked:

What is the greatest number of packages that can fit in the truck?

Solution:

First of all we will find volume of cube, then volume of rectangular prism and then simply divide the volume of prism by volume of cube to find the greatest number of packages that can fit in the truck.

$Volume\ of\ cube =a^{3}$

$=\frac{1}{4} \times\frac{1}{4}\times \frac{1}{4} =\frac{1}{64} \ cubic \ foot$

Length = 8 foot, Breadth = $6\frac{1}{4} =\frac{25}{4} \ foot$ , Height = $7\frac{1}{2} =\frac{15}{2} \ foot$

$Volume\ of\ rectangular\ prism =length\times breadth\times height$

$=8\times\frac{25}{4} \times\frac{15}{2} \\=\frac{3000}{8} =375\ cubic\ foot$

The greatest number of packages that can fit in the truck = Volume of prism divided by volume of cube

The greatest number of packages that can fit in the truck = $\frac{375}{\frac{1}{64} } =375\times64=24000\ pieces\ of\ cube$

Thus, the greatest number of packages that can fit in the truck is 24000 pieces.
