Answer: x = 20

Step-by-step explanation:

So the figures are the same, except the bigger one is bigger. It's equally bigger on all sides, so basically 6 * y = 15 to find what it is enlarged by. Then multiple 8 by y to find the missing length.

6*y = 15

/6

y = 2.5

8 * 2.5 = 20

We can also check this by:

4 * 2.5 = 10

6 * 2.5 = 15

8 * 2.5 = 20

A sample of 100 people is classified by gender (male/female) and by whether they are registered voters. The sample consists of 8
Alex_Xolod [135]

Answer:

80

Step-by-step explanation:

Using this as a guide,

Number of Registered voters = 60

Number of non registered voters = 40

Total number of women in sample is 80

Total number of men in sample is 20

Thus, the expected frequencies for female registered voters

= (80/100)*60

= 48

Expected frequency for female non registered voters is

= (80/100)*40

= 32

Therefore, the total number of females for the expected frequencies is

48+32 = 80

Katarina [22]

Answer:

7.6

Step-by-step explanation:

a^2 + b^2 = c^2

6.5^2 + x^2 = 10^2

42.25 + x^2 = 100

isolate x by subtracting 42.25 on both sides

x^2 = 57.75

square root of 57.75 or 7.6

A rug shaped like a rectangle is 2.5 meters long and 1.8 meters wide what is the perimeter in meters of the rug
Novosadov [1.4K]

Answer:

P = 8.6 m

Step-by-step explanation:

Given that,

The length of a rectangle = 2.5 m

The width of a rectangle = 1.8 m

We need to find the perimeter of the rug. The perimeter of a rectangle is given by :

P=2(l+b)

= 2(2.5+1.8)

= 8.6 m

So, the perimeter of the rug is 8.6 m.
