Answer:

d. The point value of a test item is more than 1.25 points and less than 1.5 points.

Step-by-step explanation:

Write the inequality for each scenarios, as follows:

a. defining x: container of milk cost. Data: x is at least $1.25 but less than $1.50. These mean that x >= $1.25 and x < $1.5, because $1.25 is included but $1.5 is not.

b. defining x: minutes spent on homework by the student. Data: x is at least 1.25 hours ( 1 hour 15 minutes) but no more than 1.5 hours (1 hour 30 minutes). These mean that x >= 1.25 h and x < 1.5 h, because 1.25 h is included but 1.5 h is not.

c. defining x: tip added to a restaurant bill. Data: x  is less than or equal to 1.25 (addition of 25% to the bill) or less than or equal to 1.5 (addition of 50% to the bill). In the first case x <= 1.25 and in the second one x <= 1.5

d. defining x: the point value of a test item. Data: x  is more than 1.25 points and less than 1.5 points. These mean that x > 1.25 and x < 1.5

In consequence, only the last scenario can be represented by the inequality 1.25 < x < 1.5.

Leia cuts congruent triangular patches with an area of 45 square centimeters from a rectangular piece of fabric that is 18 centi
zimovet [89]
The number of patches that Leia can cut from 32 pieces of the fabric measuring  18 cm by 10 cm will be as follows:
Number of pieces=[total area of fabric]/[area of patch]
area of fabric=18×10=180 cm²
Area of 32 patches=180×32=5760 cm²

Area of patch=45 cm²

Number of patches=5760/45=128 patches

Need answer to 2/3+5/4
Anna11 [10]

Answer:

23/12 or 1 and 11/12

Step-by-step explanation:

Your first step is that you need to gain a common denomitor. In this scenario, this is 12. To get this, you can either go through the given factors such as 3 having the factors of 6, 9, and 12 and 4 having the factors of 8, and 12.

Another method is the multiply the two given denominators together, but there are certain instances where you shouldn't do that.

Now that you have a common denominator, you need to change the numerators to accomadate the denominators. For 3 to turn into 12, you need to multiply it by 4, thus you have to do the same to the numerator. For 4 to turn into 12, you need to multiply it by 3. This will give you these two new fractions:

8/12 + 15/12

Add the numerators to get 23/12 and then simplify the two numbers to get the mixed number of 1 and 11/12.

Hope this helps!
