Answer:
Working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
Step-by-step explanation:
Given that Ted can change an advertisement on a billboard in 5 hours, while Marie can do the same job in 2 hours, to determine how long it would take them if they worked together the following calculation must be performed:
Ted 1/5 in 1 hour
Marie 1/2 in 1 hour
1/5 + 1/2 = X
5X + 2X = 10
7X = 10
X = 10/7
X = 1 3/7
60/7 x 3 = 25.71
60 x 0.71 = 42.6
So, working together, they will finish the job in 1 hour, 25 minutes, and 42.6 seconds.
Answer:
The model will be 6 toothpicks tall.
Step-by-step explanation:
your school is 30 feet tall and 1 feet is 1.26 cm, so you would most likely multiply 30 and 1.26 in order to get the height of the scale model which is 37.8 cm. Each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks So, for you to build the school, it would be 6 tp tall.
Answer:
DE=11 UNITS
Step-by-step explanation:
Given AC=CD
And AC=2AB as B is the mid point of AC
Hence 2(3x+4)=11x-17
6x+8=11x-17
11x-6x=17+8
5x=25
x=5
Hence AC=11(5)-17= 55-17=38
AC =CD = 38
CE = 49
Hence DE = CE-CD= 49-38 = 11

Answer:
5 and 6
Step-by-step explanation:
Consider perfect square numbers either side of 29
25 < 29 < 36, thus
