All _________ triangles are similar ( isosceles, equilateral) |
|
Answer» Answer: If two pairs of corresponding angles in a PAIR of triangles are CONGRUENT, then the triangles are SIMILAR. We know this because if two ANGLE pairs are the same, then the THIRD pair must also be equal. When the three angle pairs are all equal, the three pairs of sides must also be in proportion. |

Craig wants to use an elevator to carry identical packages having the same weight. Each package weighs 4 pounds and Craig weighs 90 pounds. If the elevator can carry a maximum of 330 pounds at a time, which inequality shows the maximum number of packages, n, that Craig can carry with himself in the elevator if he is the only passenger?n ≥ 60n ≤ 60n ≤ 236n ≥ 236 |
|
Answer» Given: WEIGHT of each package = 4 pounds Weight of Craig = 90 pounds Number of maximum PACKAGES = n Maximum weight that the elevator can carry = 330 pounds To FIND: The correct ineqaulity. Solution: The total weight of Craig and n packages must be less than or equal to 330, as the maximum weight that the elevator can HANDLE is 330 pounds. 90 + n*4 ≤ 330 4n ≤ 330- 90 4n ≤ 240 n ≤ 60 Therefore the correct option is (B) i.e. n≤ 60. |

Calculate the mass, in kilograms, of an object that occupies .253 dm3 and has a density of 4.14 g/cm3. |
|
Answer» Answer: 1000 Step-by-step explanation: Explanation: Alright so we know the formula for density is ρ = m v => where ρ is the density with units of the derived components, m is the MASS, and v is the volume. We can rearrange this formula to get US the volume. By doing so, we get v = m ρ . I got to this conclusion by using the "Triangle Method" - a diagram that provides an understand to how simple equations (multiply and DIVIDE) relate to one another. I noticed that the density of the object is 4.0 g c m 3 . That means that the derived components are the mass (in grams) and volume (in cubic centimetres). Thus we have to convert the mass from 4 k g to grams. We can do this by multiplying the mass by 1000 . We get 4000 g . Now we can use the formula we REARRANGED and plug in the numbers to solve for the volume. v = m ρ = 4000 4 = 1000 Therefore, the volume of the space that the object occupies is 1000 c m 3 . Hope this helps :) |

Emanuel was charged $32 for a 14 2/9 taxi ride. What was the cost per kilometer? |
|
Answer» $2.25 per kilometer Step-by-step explanation: Here we are asked for the unit RATE, dollar per kilometer, that is $/KM . If EMANUEL was charged $32 we need to divide that amount by the kilometers traveled, so, 32 / (14 2/9) =32 / (128/9) =32 * 9 / 128 =288 / 128 = $ 2.25 per km So the cost per kilometer traveled is $2.25 per km. Hope this helps!! |

riley reached into his pocket and pulled out a total of 27 coins, consisting of quarters and dimes. if the total value of the coins is $5.55, how many quarters does he have? |
|
Answer» Answer: Step-by-step explanation: To solve this, we can set up a system of equations. Let's FIRST name our variables. x: number of quarters y: number of dimes Using this, we can WRITE the following equations. Number of coins: x+y=27 Total Value: 0.25x+0.1y=5.55 We can rewrite the first equation to x=27-y by subtracting y from btoh sides. This way, we can substitute 27-y in for x. 0.25(27-y)+0.1y=5.55 Distribute. 6.75-0.25y+0.1y=5.55 Combine like terms. 6.75-0.15y=5.55 Subtract 6.75 from both sides. -0.15y=-1.2 Divide both sides by -0.15 y=8 There are 8 dimes. We can use that to find the number of quarters by PLUGGING it in to one of the equations. x+y=27 x+8=27 Subtract 8 from both sides. x=19 He has 19 quarters. |

A car covers a distance of 270 kms with some speed. If the speed isdecreased by 10 km/hr, it will take 54 minutes more to cover the samedistance. Find the original speed of the car. |
|
Answer» Answer: Let the original speed of the car =xkm/hr ∴ Time taken by it to cover 72km= x 72
hrs NEW speed of the car = (x+10)km/hr ∴ New time taken by the car to cover 72km= x+10 72
hrs As per the given condition, time is REDUCED by 36 minutes ∴ x 72
− x+10 72
= 60 36
x 2 +x−1200=0 On solving we get, x=−40 or x=30 Since the speed cannot be negative, so x=30km/hr. |
