Answer:

102 cm

Step-by-step explanation:

Diagonals of a rhombus are perpendicular.
Sides are of equal length.

Use Pythagorean to work out the side length.

a² = (d₁/2)² + (d₂/2)²
a² = (24/2)² + (45/2)² = 650.25
a = √650.25
a = 25.5 cm

The perimeter is:

P = 4a
P = 4*25.5 = 102 cm

PROBLEM SOLVING You are participating in an orienteering competition. The diagram shows the position of a river that cuts throug

Wewaii [24]

Answer:

The shortest distance is 2.2 miles

Step-by-step explanation:

we know that

The shortest distance you must travel to reach the river is the perpendicular distance to the river

step 1

Find the slope of the line perpendicular to the river

we have

$y=3x+2$

The slope of the river is m=3

Remember that if two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is -1)

therefore

The slope of the line perpendicular to the river is

$m=-1/3$

step 2

Find the equation of the line into point slope form

$y-y1=m(x-x1)$

we have

$m=-1/3$

$point(2,1)$

substitute

$y-1=-(1/3)(x-2)$

step 3

Find the intersection point of the river and the line perpendicular to the river

we have

$y=3x+2$ ------> equation A

$y-1=-(1/3)(x-2)$ -----> equation B

Solve the system by graphing

The intersection point is (-0.1,1,7)

see the attached figure

step 3

Find the distance between the points (2,1) and (-0,1,1.7)

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute

$d=\sqrt{(1.7-1)^{2}+(-0.1-2)^{2}}$

$d=\sqrt{(0.7)^{2}+(-2.1)^{2}}$

$d=2.2\ miles$

Assoli18 [71]

Probably angles of a triangle

$\\ \sf\longmapsto 2x+78+132=180$

$\\ \sf\longmapsto 2x+210=180$

$\\ \sf\longmapsto 2x=|-30|=30$

$\\ \sf\longmapsto x=15°$

The three sides of a triangle measures 9.97

stira [4]

I think 3.323 units would be the correct answer. Are you asking what the length of a single side is?

What is the ratio of dimes to pennies in a dollar

maw [93]

Well, there are 100 pennies in a dollar, and 10 dimes in a dollar. So, the ratio could be 10:100, or 1:10.
