3.  \frac{4}{5} = \frac{x}{15}

5 * x = 4 * 15

5x = 60

5. How can a teacher help children who have articulation problems?
natka813 [3]

A way a teacher can help the student by using preferential seating, so that the student can see the teacher's mouth when he/she is speaking. Reduce background noise in the classroom. Use preferential seating, so that the teacher can more privately model correct articulation to the student. Give additional time for the student to speak. This way the child will have an easier time learning.

Find the area of the circle. Round your answer to the nearest hundredth with 3in i really need help
REY [17]

Answer:

The area of the circle with a 3-inch diameter is 7.07 square inches.

Step-by-step explanation:

The formula for the area of a circle is

A = πr²

If you are given diameter, take half of that to get the radius:  3 ÷ 2 = 1.5

Then take the radius, 1.5 and square it  (multiply by itself)  1.5 × 1.5 = 2.25

Then multiply r² times pi. You can use 3.14. (sometimes you will need 3.14159)

2.25 × 3.14 = 7.065

Your instructions are to "round to the nearest hundredth" so you look to the thousandth place and see a 5. Rules fro rounding: "If the number is 5 or higher, add 1 to the place you are rounding to. If 4 or less, leave the place as it is."

You see a 6 in the hundredths place. Add 1. so the rounded answer is 7.07.

Then you put in the units measure. Inches are given, so the Area will be square inches

7.07 in²
