Answer:
18 inches
Step-by-step explanation:
Rick is building a scale model of the Alamo.
We are given a scale that 3 in. = 15 ft.
The length of the Alamo is 90 feet.
What is the length of the scale model in inches?
So we know that for every 15 feet, 3 inches are actually used in the project and we need a total of 90 feet. To solve, we need to find how many times 15 goes into 90, in which the number it multiplies to will apply to the inches.
15 * ? = 90
90 / 15
6
It takes 15 6 times to get to 90, meaning that we need to multiply 3 inches 6 times to find the actual length of the scale model in inches.
3 * 6
18 inches.
Answer:
3
Step-by-step explanation:
We need to find the unit price of each box.
So, a box that weighs 30 Oz costs $4.50.
lets say that 30 Oz box is named box 1. We can use unitary method to find out the unit price of box 1.
Unitary method is a process to find the value of a single unit.
Now,
30 Oz costs $4.50
therefore, 1 Oz should cost:
dollars
So, the unit price of box 1 is $0.15.
Now, lets say the 20 Oz box is named box 2. Again we can use unitary method to find out the unit price of box 2.
Now,
20 Oz box costs $3.60
therefore, 1 Oz should cost:
dollars
So, the unit price of box 2 is $0.18.
Answer: 0.271
Step-by-step explanation:
Probability of complement of an even is 1 decreased by the probability of the event
P(At least one) =1 - P(none)
The probability that of testing negative is 0.9 because the probability of testing positive is 0.1
P( at least one) = 1 - P(none) = 1 - (0.93^3) = 0.271
The exterior angles of a triangle always add up to 360, so 360 - 130 - 134 = 96
X=96
