explain how you can use a grid to subtract 1.65 - 0.98
Explain why one column in a hundredths grid is equal to one column in a tenths grid?
A straight road separates towns A (grid ref 42,45) and B (grid ref 52,40) A village is situated at grid ref (46,57) and a new road is planned from the village to road AB. What is the shortest road possible (1 dp) Please define an origin and a set of axes Use Cartesian geometry principles to work out lenght of the shortest line The shortest route to the road would be perpendicular to the road. The origin of coordinates has already been designated as where the grid is (0,0). The axis have also been defined as the map grid. The "slope" of the road on the map from A to B, relative to the x axis, is (40-45)/(52-42) = -1/2. That means the slope (direction) of the line from the village at (46,57) to road AB is +2 (since it is perpendicular to AB). The equation for the new road is y - 57 = 2(x - 46) y = 2x - 35 The roads connect where the equation of the AB road is also valid: (y - 45) = (-1/2) (x - 42) y = -(1/2)x + 66 Solve the two equations: 0 = 2.5 x - 101 x = 40.4 y = 45.8 Shortest new road length = sqrt[(46 - 40.4)^2 + (57 - 45.8)^2] = 12.52 Check the math; the method should be OK. Also try plotting it on graph paper to see if it makes sense.
Imagine that the grid lines on acoordinate grid are streets and that the distance between two pointsmust be measured by the number of “blocks” a taxicab would haveto travel horizontally and vertically to get from one point to theother. The sum of the horizontal and vertical distances is called thetaxicab distance. A cab driver estimates that traveling one blockduring rush hour takes about 5 min.Use the information to answer the question below: What general rule can you use to find the taxicab distancebetween two points on a grid?
can you explain to me how to add and subtract fractions like 2/5 + 5/12 or 7/12 - 8/9? i'm having trouble on this and i'm always forgetting how to do it.
Explain how to use a hundred chart to subtract?
Explain how you would use front-end estimation to subtract 189 from 643.
a certain cross section lies in the x-y plane. If 3x10^20 electrons go through the cross section in the z-direction in 4 seconds, and simultaneously, 1.5x10^20 protonsgo through the same cross section in the negative z-direction, what is the magnitude and direction of the current flowing through the cross section?
Explain how you can use a hundred chart to subtract 12 from 46.
please can someone help me with this math grid here is a grid with squares. you must place the numbers 1 through 8 in the squares, without consecutive numbers being placed next to each other in a row, a cloumn, or diagonally.so the number 3 cannot be placed next to the number 2 and 4, also the grid has 2 blocks on top 4 in the middle and 2 on the bottom
