Answer:
x = 39
Step-by-step explanation:
In the image, in order for DE to be parallel to CB, the scale factor between AE and EB should be the same as between AD and DC. To solve this, you first need to identify these lines:
AE = 12, EB = x - 3
AD = 6, DC = 18
Now, you need to find the scale factor by dividing 18 by 6:
18 ÷ 6 = 3
So the scale factor from AD to DC is 3. This means that the scale factor from AE (12) to EB should also be 3. You can find x by writing and solving an equation:
12 × 3 = x - 3 (given)
36 = x - 3 (simplify)
x = 39 (add 3 to both sides)
So x = 39.

Plan A $17 plus 0.10 for each min of calls. Plan B &13 plus an additional 0.15 for each min. What amount do the two plans cost the same?
Answers
Answer:
80 minutes ; $25
Step-by-step explanation:
Let x = number of minutes
Plan A :
17 + 0.1x - - - (1)
PLAN B :
13 + 0.15x - - - (2)
Both plans will cost the same when ;
17 + 0.1x = 13 + 0.15x
Solve for X
0.1x - 0.15x = 13 - 17
-0.05x = - 4
divide both sides by - 0.05
-0.05x / - 0.05 = - 4 / - 0.05
x = 80 minutes
Amount :
17 + 0.1(80) = 17 + 8 = $25
Bonnie's doctor recommended that she drink 2cups of milk per day. If she buys 3 quarts of milk,will it be enough milk to last 1 week?
Answers
Answer:
She does not have enough milk to last for 1 week
Step-by-step explanation:
From the question, we are told that:
Bonnie's doctor recommended that she drink 2cups of milk per day.
Step 1
The number of days in a week is 7 days
Hence
1 day = 2 cups of milk
7 days = x
Cross Multiply
x = 7 × 2 cups of milk
= 14 cups of milk.
Step 2
If she buys 3 quarts of milk,will it be enough milk to last 1 week?
We have the conversion rate as:
1 quart = 4 cups
Therefore,
1 quart = 4 cups
3 quarts = x cups
Cross Multiply
x cups = 3 quarts × 4 cups/1 quart
x cups = 12 cups of milk
This means she bought 12 cups of milk.
Therefore, from the above calculation, she does not have enough milk to last for 1 week because due to her doctor's recommendation, she need 14 cups of milk for the week but she only bought 12 cups of milk

Given :
Height of patio, h = 8ft
Base of patio = 17 ft
Cost of carpeting = $6.50 per ft²
Area of triangular patio :
Area = 1/2 * base * height
Area = 0.5 * 17 * 8

A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.
The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?
Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
