math
A woman has a total of \$9,000 to invest. She invests part of the money in an account that pays 5% per year and the rest in an account that pays 12% per year. If the interest earned in the first year is \$730, how much did she invest in each account?

Physics
A hiker, who weighs 990 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 3550 N, and rests on two concrete supports, one at each end. He stops one-fifth of the way along the bridge. What is the magnitude of the force that a...

algebra
The third angle in an isosceles triangle is 56° more than twice as large as each of the two base angles. Find the measure of each angle.

intermediate algebra
A triangle is such that the largest angle is 11 times the smallest angle. The third angle is 27° less than the largest angle. Find the measure of each angle. (Enter solutions from smallest to largest.)

physics
A train 400 m long is moving on a straight track with a speed of 80.1 km/h. The engineer applies the brakes at a crossing, and later the last car passes the crossing with a speed of 16.9 km/h. Assuming constant acceleration, determine how long the train blocked the crossing. D...

physics
A car starts from rest and travels for 6.0 s with a uniform acceleration of +2.4 m/s2. The driver then applies the brakes, causing a uniform acceleration of −1.0 m/s2. If the brakes are applied for 3.0 s, determine each of the following. (a) How fast is the car going at ...

Physics
There is no given figure, you have to draw it from the question.

Physics
The figure shows the treatment of fractures of the humerus shaft with a cast of the upper arm bent by 100 to 110 degrees at the elbow joint, and an attached traction device. The traction device keeps the upper arm under tension to lower the risk of fracture dislocation due to ...
