Answer:

  a) w = 8; y = 5.25

  b) x = 10; z = 7.2

Step-by-step explanation:

a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.

  6 = (3/4)w

  w = 24/3 = 8

  y = (3/4)·7 = 21/4 = 5.25

__

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.

  6 = (3/5)x

  x = 30/3 = 10

  z = (3/5)12 = 36/5 = 7.2

Sally either walks, cycles or drives to work. She walks about 15% of the time and drives about 3/5 of the time. What percentage
Ivan

Answer:

25%

Step-by-step explanation:

We need to first convert 3/5th to percentage so we are only dealing with percentage.

3/5 doing division would give us 0.6

Multiply that by 100, we get

0.6 * 100 = 60%

Thus, now we can say:

Walking = 15%

Driving = 60%

The remaining time is cycling. How much?

15 % + 60 % + cycling = 100%

75% + cycling = 100%

Cycling = 100 - 75 = 25%

Can I please get some help with this probem?
Lemur [1.5K]

Answer:

In Step 4, the inequality sign should be flipped.

Step-by-step explanation:

Whenever you multiply or divide both sides of an inequality by a negative number, you need to flip the inequality sign. So, in Step 4, when you divide both sides by -10, the sign should be flipped.

The final answer should be:

\frac{-27}{10} \geq x
