Answer:

463 rounded

Step-by-step explanation:

4/3 times pi times r times r times r.

4.8 x 4.8 x  4.8 = 110.592 x 3.14 x 4/3 = 463

Volume of sphere is 463.01 [tex]cm^{3}[/tex].

The volume of sphere is the measure of space that can be occupied by a sphere. If we draw a circle on a sheet of paper, take a circular disc, paste a string along its diameter and rotate it along the string. This gives us the shape of a sphere.

Volume of sphere = [tex]\frac{4}{3}\pi r^{3}[/tex]

Given

Radius of sphere r = 4.8 cm

Volume of sphere

V = [tex]\frac{4}{3}\pi r^{3}[/tex]

V = [tex]\frac{4}{3} \pi (4.8)^{3}[/tex]

V = 463.01 [tex]cm^{3}[/tex]

Volume of sphere is 463.01 [tex]cm^{3}[/tex].

Answer:

x = 12 and y = 11

Step-by-step explanation:

4x+3y=-15 -----equation 1st

4x-y = -27 ____equation 2nd

then,

Multiple equation second by 3 and slove it with equation first

4X +3Y = -15

12X -3Y = -81 (Multiples it with 3)

-8x = -96 (subtracted)

x=-96/-8

therefore, x=12

again,

from equation first

4x+3y = -15

or 4 × 12 + 3y = -15

or 3y = -15+48

or 3y= 33

or y=33/3

therefore, y =11

I hope this helps. If you have any doubt feel free to ask!!

Answer:

x = -6,  y = 3

Step-by-step explanation:

1)  4x + 3y = -15

2)  4x - y =  -27

     0 + 4y = 12       subtract equation (2) from equation (1)

4y = 12

y = 12/4 = 3         substitute y = 3 into either equation 1 or 2 and solve for x

4x + 3(3) = -15

4x = -24

x = -6

Check your answers by plugging x = -6, y = 3 into the equations:

4(-6) + 3(3) = -15   correct!

4(-6) - 3 = -27        correct!

Answer:

D

Step-by-step explanation:

i think i do am not si sure

Answer:

A, the first option

Step-by-step explanation:

1. Add 15 to both sides to cancel out the 15 from the left. (5x < -50)

2.  Divide both sides by 5 to cancel out the 5 from the left. ( x < -10)

This inequality does not include the -10 because it's less than -10 not less than or equal to. So, the point at -10 should not be filled in.

x has to be LESS than, so the graph should include numbers that are less than -10 which leads us to our answer, A.

Step-by-step explanation:

As per table we have:

32 students in 1 school bus

Given:

The figure of a rhombus.

To find:

The measure of angle 1.

Solution:

First label the vertices of the rhombus as shown in the below figure.

We know that the opposite angles of a rhombus are congruent and the diagonals of a rhombus bisect each vertex angle.

[tex]m\angle ABD=m\angle CBD=30^\circ[/tex]       (Diagonal BD is the angle bisector)

Now,

[tex]m\angle ABC=m\angle ABD+m\angle CBD[/tex]  

[tex]m\angle ABC=30^\circ+30^\circ[/tex]

[tex]m\angle ABC=60^\circ[/tex]  

We know that the consecutive angles of a rhombus are supplementary. It means the sum of each pair of consecutive angles is 180 degrees.

[tex]m\angle BAD+m\angle ABC=180^\circ[/tex]

[tex]m\angle 1+60^\circ=180^\circ[/tex]

[tex]m\angle 1=180^\circ-60^\circ[/tex]

[tex]m\angle 1=120^\circ[/tex]

Therefore, the measure of angle 1 is [tex]m\angle 1=120^\circ[/tex].

Answer:

KM = 180° - 133° = 47°

KM = 47°

Answer:

it's C

Step-by-step explanation:

-16 means where the line crosses y axis

The locations of the points on the number line are:

point 1: 1 step to the right of 0.

point 4: 4 steps to the right of 0.

point -3:  3 steps to the left of 0

A number lines is an horizontal straight line in which the integers are placed in equal intervals.

All positive numbers on the number line are on the right side of zero while the negative numbers are on the left side of zero.

To locate 1: starting from 0, count 1 step to the right.

To locate 4: starting from 0, count 4 steps to the right.

To locate -3: starting from 0, count 3 steps to the left.

Answer: The correct answer is C. Jana has a higher ratio of hits to total attempts, so she has a better batting average. This can be calculated by dividing the number of hits by the number of attempts: Jana's batting average is 7/10 = 0.7, and Tasha's batting average is 10/16 = 0.625. Since 0.7 is greater than 0.625, Jana has a higher batting average.

well, that number is "x", which oddly enough is the 100%, now, we also know that 30% of that is 1260, so hmmmm

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 1260& 30 \end{array} \implies \cfrac{x}{1260}~~=~~\cfrac{100}{30} \\\\\\ \cfrac{ x }{ 1260 } ~~=~~ \cfrac{ 10 }{ 3 }\implies 3x=12600\implies x=\cfrac{12600}{3}\implies x=4200[/tex]

Answer:

$1,158.08

Step-by-step explanation:

The value of the car in year 10 is $1158.08

From the table, we have the following points

(x, y) = (1,5000) and (2,4250)

Start by calculating the rate of depreciation using:

r = y2/y1

So, we have:

r = 4250/5000

Evaluate

r = 0.85

The value of the car in nth year is calculated using:

y = y1 * r^(n - 1)

For the 10th year, we have:

y = 5000 * 0.85^(10 - 1)

Evaluate the product

y = 1158.08

Hence, the value of the car in year 10 is $1158.08

Explanation:

If you graph the points and connect them, you'll see the triangle they're asking about. Yhe base of the triangle is 9 and the height is 8. The area of a triangle is half of the base times the height. So multiply 8 by 9 and you get 72. This is twice the area. So divide it by 2 and you get 36, which is the area of the triangle. So the answer is A.

Permutation without repetition

Step-by-step explanation:

The order of the cards matter, which makes it a permutation, but since none of the cards are exactly the same, repetition isn't allowed/possible

The problem is of the type permutation without repetition.

What is permutation and combination?

Permutation and combination are the methods used in counting how many outcomes are possible in various situations. Permutations is used in the case of arrangements and combinations is used in the case of selections.

In the given scenario, the order of cards is a priority therefore, permutation will use.

Also, the cards are not repeating in the scenario.

Answer:

Step-by-step explanation:

When increasing the power of an integer by another power, you should multiply both powers to find the total power that the integer should be raised to. In this case therefore:

= 3 * 2

= 6

So the numerator will be 8⁶

When dividing the same integers raised to powers, you should subtract the power of the divisor from the power number being divided.

In this case therefore, you are to subtract (-5) from 6 (calculated in first part).

= 6 - (-5)

= 6 + 5

= 11

Another way of writing the above will therefore be: 8¹¹.

Step-by-step explanation:

1. a) q=4+0.8(7)

q=4+5.6

q=9.6

b) q=4+0.8(100)

q=4+80

q= 84

2. a) 12=4+0.8p

-4 -4

8=0.8p

0.8 0.8

10=p

b) 60=4+0.8p

-4 -4

56=0.8p

0.8 0.8

70=p

Answer:

Q1. a) q= 9.6

b) q= 84

Q2. a) p= 10

b) p= 70

Step-by-step explanation:

Substitute the equation with the given value and solve the equation to arrive at the answer.

Q1. a) q= 4 +0.8p

When p= 7,

q= 4 +0.8(7)

q= 4 +5.6

q= 9.6

b) q= 4 +0.8p

When p= 100,

q= 4 +0.8(100)

q= 4 +80

q= 84

Q2. a) q= 4 +0.8p

When q= 12,

12= 4 +0.8p

0.8p= 12 -4 (-4 on both sides)

0.8p= 8

p= 8 ÷0.8 (÷0.8 on both sides)

p= 10

b) q= 4 +0.8p

When q= 60,

60= 4 +0.8p

0.8p= 60 -4 (-4 on both sides)

0.8p= 56

p= 56 ÷0.8 (÷0.8 on both sides)

p= 70
