Answer:

8 cm and 9 cm

Step-by-step explanation:

The other two sides added together have to equal a larger number than 13, since 13 is the largest side.

5 + 8 = 13

6 + 7 = 13

7 + 2 = 9

8 + 9 = 17

A garden store is purchasing iris bulbs to sell for spring planting. Each year the store sells two varieties of iris bulbs. Purp

RoseWind [281]

Answer:

390

Step-by-step explanation:

Only two varieties are involved: yellow and purple.

We know the ratio of yellow iris bulbs over the total is 2:5, so 40%.

That leaves 60% of the sales for the purple bulbs.

purple = (60% / 40%) * 260 = 1.5 * 260 = 390.

So, they sold 1.5 times more purple bulbs than yellow ones.

In total, the store sold 650 bulbs last year, and we hope they sell more this year.

Write an equation of the line that is parallel to x=-11 that passes through the point (-9, 0).

zysi [14]

X=-9

There is no slope in either equation. Therefore, x=-11 and x=-9 will be two vertical and parallel lines at (-11,0) and (-9,0)

Two forces with magnitudes 300 pounds and 450 pounds, with an angle of 60° between them, act upon an object. What is the approxi

kifflom [539]

Answer:

653.84 lbs.

Step-by-step explanation:

To make the computation simple, assume the 450 lb force acts along the x axis in the positive direction.

The x component of the 300 lb force is 300cos(60)=150 lbs.

The y component of the 300 lb force is 300sin(60)= $300*\frac{\sqrt{3} }{2} =259.81\\$ lbs.

The x component of the total force is the sum of the x components of the two forces.

Fx=150+450=600

Fy=259.81

The net force is obtained using the Pythagorean theorem, since the two force components are perpindicular.

F=Sqrt(Fx^2+Fy^2)=Sqrt(360000+67501.24)=Sqrt(427501)=653.84 lbs.
