When a golf ball is hit with two iron, it rotates at a rate of 8 1/3 times/second. How many times does this ball rotate if it is airborne for 7 1/3 seconds? - On day
On the first day of the trip, they drove 1/4 of the total distance. On day two, they drove 1/2 of the total distance. What fraction of the total distance is left to travel? - My brother
My brother is missing 240 assignments. He wants to finish them all. If he does two each day, how many days will it take for him to finish 1/3 of his assignments? - Quadrant four
Which point is located in Quadrant IV? A coordinate plane. A(-8, 6) B(-8, -6) C(8, -6) D(8, 6) - A map 4
A map represents every 4 miles with 1 inch. If a school and a bank are 12 miles apart, how far apart are they on the map, in inches? - Chocolate bar
Shen's chocolate bar is 54% cocoa. If the weight of the chocolate bar is 54 grams, how many grams of cocoa does it contain? Round your answer to the nearest tenth. - Walking woman
Reeta walks 5/7 km in 1 hour. How far does she go in 3 1/2 hours? - The temperature 13
The temperature in Toronto at noon during a winter day measured 4°C. The temperature started dropping 2° every hour. Which inequality can be used to find the number of hours, x, after which the temperature will measure below -3°C? - The oscillation
The oscillation of a mechanical oscillator can be used to measure weight. A body of the unknown weight is suspended on a spring with a stiffness of 20 N times m. The resulting oscillator oscillates with a frequency of 1.6 Hz. Find the weight of the body. - A map 3
A map is drawn on a scale of 1:25000. This scale can be expressed as 1 cm representing n km. Find n. - Your Mom
Your Mom can clean your entire house in 3 hours. However, your dad takes 5 hours to clean the house. How long will it take for them to clean the house if they work together? (Write the numerical answer round to the nearest thousandth) - Bike path
Bill was riding his bike on a bike path that was 5 1/4 miles long. He rode his bike awhile and stopped for s drink or water. Then he rode 2 7/10 miles and was at the end of the path. How far had Bill ridden before he stopped for water? - Direction indicator
When a current of 1.6 A passes through the lamp direction indicator's 7400 mOhm resistance, which voltage is connected to it? - Resistance 49711
The car's low beam bulb filament has a resistance of 5 Ω. How much electric current flows through it at the standard car battery voltage of 12 V? - Frequency of oscillation
A weight of 1 kg was suspended from the spring, and the spring was extended by 1.5 cm. Determine the frequency of the natural oscillation of the resulting oscillator. - Dynamometer
What is the volume of a body that stretches a dynamometer in air, on which a force of 2.5 N suspends it, and if it is immersed in alcohol with a density of 800 kg/m³, does it tension the dynamometer with a force of 1.3 N? - Draw SSA triangle
Draw a triangle ABC if you know: alpha = 60° side b = 4 cm side a = 10 cm - Steering 49363
The steering wheel has a diameter of 40 cm. It is acted upon by a pair of forces with a torque of 27 Newton-meters. How much force does it exert on each side of the steering wheel? - Lead melt
Find the heat needed to melt an object made of lead weighing 250g and an initial temperature of 35°C. Lead melts at 327°C at normal pressure. Mass heat capacity of lead c = 129 J/kg • K and mass latent heat of lead lt (t is the subscript) = 22.6 kJ/kg.
