there are 10 numbers you want either a 4 or 7 ( 2 numbers)

so probability is 2/10 which reduces to 1/5

Find the value of x, y, z in the rhombus below

galben [10]

Answers:

x = -28
y = -12
z = -11

===========================================================

Explanation:

Any rhombus is a parallelogram, but not the other way around.

For any parallelogram, the opposite angles are congruent.

-8y-8 = 88

-8y = 88+8

-8y = 96

y = 96/(-8)

y = -12

Also, for any parallelogram, the adjacent angles are supplementary (meaning they add to 180).

(-3x+8) + (88) = 180

-3x+96 = 180

-3x = 180-96

-3x = 84

x = 84/(-3)

x = -28

And we can also say,

88 + (-9z-7) = 180

-9z+81 = 180

-9z = 180-81

-9z = 99

z = 99/(-9)

z = -11

Use a special product pattern to solve (x-5)(x+5) and (3+8v)(3-8v)

Inessa05 [86]

(X - 5) (x + 5)

X^2 + 5x - 5x - 25

=X^2 -25

(3 + 8v) (3 - 8v)

9 - 24v + 24v - 64v^2

= 64v^2 + 9

a town park has 2 biking trails. Marsh Trail is 5 and three over ten miles long. Woodland trail is 2 and 4 over 5 miles long. Ho

Marsh Trail is longer than Woodland trail by 2.5 miles

Step-by-step explanation:

A town park has 2 biking trails

1. Marsh Trail is 5 and three over ten miles long

2. Woodland trail is 2 and 4 over 5 miles long

We need to find that Marsh Trail is how much longer than

Woodland trail

To do that we will subtract the length of the Woodland trail from the

length of the Marsh Trail

∵ The length of Marsh Trail is 5 and three over ten miles

- 5 and three over ten = $5\frac{3}{10}$

∵ $\frac{3}{10}$ = 0.3

∴ $5\frac{3}{10}$ = 5.3 miles

∵ The length of Woodland trail is 2 and 4 over 5 miles

- 2 and 4 over 5 = $2\frac{4}{5}$

∵ $\frac{4}{5}=\frac{4*2}{5*2}=\frac{8}{10}$ = 0.8

∴ $2\frac{4}{5}$ = 2.8

∴ The difference = 5.3 - 2.8

∴ The difference = 2.5 miles

Marsh Trail is longer than Woodland trail by 2.5 miles
