Answer:
Translation, rotation and reflection
Step-by-step explanation:
Congruent images remain the same.
Translation, rotation and reflection preserve congruence while dilation will not.
How many tiles does she need ?
1 square meter = 10,000 cm²
12 square meters = 120,000 cm²
Each tile = (20 cm x 20 cm) = 400 cm²
Tiles needed = 120,000 / 400 = <u>300 tiles</u>
How many tiles can she buy ?
1,000 / 34.99 = 28 boxes, with 20.28 left over . . . not enough for another box.
28 boxes of 10 tiles per box = <u>280 tiles</u>
Halima doesn't have enough money to buy enough tiles
to cover the wall. She can only buy 280 tiles, but it would
take 300 to cover the wall.
She can cover 280/300 = 93 and 1/3 percent of the wall,
leaving 6 and 2/3 percent with the old ugly plaster showing.
Maybe she could leave the bare part down at the bottom, and
then hide it with a table up against the wall.
The answer is the last one. This is because negatives don't work in a square root.
Answer: he would need to ride at least 13.3 miles
Step-by-step explanation:
The total amount that Grant needs to make in a day is greater than or equal to $15.
He has an agreement with Brian to rent the bike for $35.00 a night.
He charges customers $3.75 for every mile he transports them. If he transports the customers over x miles, his total revenue would be
3.75 × x = 3.75x
Profit = revenue - cost. Therefore,
his profit would be
3.75x - 35
Therefore,
3.75x - 35 ≥ 15
3.75x ≥ 15 + 35 = 50
x ≥ 50/3.75
x ≥ 13.3
