A bowling ball has a total diameter of 8.5 in. It consists of 2 parts. The inside is a spherical core with a diameter of 6 in.Surrounding the core is a layer of polyurethane.What is the volume of the polyurethane? Use 3.14 to approximate [tex] \/pi [tex] and round your answer to one decimal place.

___ in3

Answers

so first find the volume of the spere and the volume of the core then subtract the core from the squarere

so

volume of squrere formula 4/3pi times radius^3

diameter=2radius
diameter/2=radius

8.5/2=radius=4.25

4/3 times pi times 4.25^3=321.39

inner core= 4/3 times pi times r^3
diameter/2=6/2=radius=3

4/3 times pi times 3^3=113.04

subtract

sphere-core=321.39-113.04=208.352
round to 1 decimal place

the answer is 208.4 cubic inches

In a line of students, Jenna is number 8.The teacher says that a rule for a number pattern is add 4. The first student inline says the first term, 7. What number should Jenna say?

Answers

Answer:

Formula for nth term in Arithmetic sequences is:

$a_n =a+(n-1)d$

where a is the first term, d is the common difference and n is the number of terms.

As per the statement:

The rule for the pattern is add 4.

As the first term in line says the first term i,e 7

$a= 7$

common difference(d)= 7

As the Jenna number is 8th in line.

Series we get;

7, 11, ......... $a_8$

We have to find the 8th term.

n = 8, a = 7 and d = 4

Using above formula:

$a_8 = 7+(8-1)4 = 7+7 \cdot 4 = 7 +28 = 35$

Therefore, 35 number should Jenna say.

7 , 11 , 15,19,23,27,31,35. Jenna should say 35.

you have been asked to build a scale model of your school out of toothpicks imagine your your school is 30 ft tall your scale is 1ft:1.26cm if a toothpick is 6.3 cm tall how many toothpicks tall will your model be

Answers

If your school is 30 feet tall and 1 feet is 1.26 cm, you would multiply 30 and 1.26 to get the height of the scale model which is 37.8 cm. Then, if each toothpick is 6.3 cm, you would take 37.8 and divide it by 6.3 to get the number of toothpicks you need to build the school, which is 6.

The model will be 6 toothpicks tall.

Answer:

The model will be approximately 5 cotton swabs tall.

The model will be 6 toothpicks tall.

Step-by-step explanation:

Find the number of centimeters in the scale model represented by 1 foot on the actual school.

1 ft

1.26 cm

1 foot on the actual school equals 1.26 centimeters on the scale model.

Find the height for your scale model represented by the height of the school.

1 ft × 30

1.26 cm × 30

30 ft

37.8 cm

The school will be 37.8 cm tall in your model.

To find how many toothpicks tall your model will be, divide its total height by the height of one toothpick.

37.8 cm ÷ 6.3 cm = 6

The model will be 6 toothpicks tall.

To find how many cotton swabs tall your model will be, divide the height of the model by the height of one cotton swab. If necessary, round to the nearest whole number.

37.8 cm ÷ 7.7 cm ≈ 5

The model will be approximately 5 cotton swabs tall.
