A crew is made up of 8 men; the rest are women. If 32 % of the crew are men, how many people are in the crew?

Lelechka [254]

Answer:

Step-by-step explanation:

(66 2/3)

---------- (x) = 8

100

Solve for x

(66 2/3)x = 800

x = 800/(66 2/3)

x = 800/(200/3)

x = 800(3/200)

x = 4(3)

x = 12

Triangle GFH has vertices G(2, –3), F(4, –1), and H(1, 1). The triangle is rotated 270° clockwise using the origin as the center

Rufina [12.5K]

Answer:

See attachment.

Step-by-step explanation:

The given triangle,GFH has vertices G(2, –3), F(4, –1), and H(1, 1).

When this triangle is rotated 270° clockwise using the origin as center of rotation; then the coordinates of the image triangle, G'F'H' can be obtained using the mapping;

$(x,y)\to (-y,x)$

This implies that the new triangle will have vertices at;

G'(3, 2), F'(1, 4), and H'(-1, 1).

The correct choice is shown in the attachment.

Simplify: (6x-4) (9x-2)

Vinil7 [7]

Step-by-step explanation:

Hey, there!!

While simplifying the algebraic expression, you must be very careful about the signs.

Here,

(6x-4) (9x-2)

Multiply 2nd expression by 1st expression,

= 6x ( 9x - 2) -4 ( 9x - 2)
