Answer:

[tex]\frac{ds}{dt} =31.952[/tex]

Step-by-step explanation:

From the question we are told that

Cube increase rate 459 cubic inches

At 408

Generally the expressions of the is mathematically given to be

[tex]\frac{dv}{dt} =459[/tex]

[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]

[tex]v=408[/tex]

Generally

[tex]v=l^3[/tex]

Therefore solving Mathematically

[tex]\frac{dv}{dt} =3*l^2 \frac{dl}{dt}[/tex]

[tex]459 =3*(7.416859539)^2 \frac{dl}{dt}[/tex]

[tex]459 =165.0294163\frac{dl}{dt}[/tex]

[tex]\frac{dl}{dt} =\frac{165.0294163}{459}[/tex]

[tex]\frac{dl}{dt} =0.359[/tex]

Therefore solving mathematically for surface area

[tex]Surface area S=6l^2[/tex]

[tex]\frac{ds}{dt} =6(2l* \frac{dl}{dt})[/tex]

[tex]\frac{ds}{dt} =12l* \frac{dl}{dt}[/tex]

[tex]\frac{ds}{dt} =12*(7.416859539)*0.359[/tex]

[tex]\frac{ds}{dt} =31.95183089[/tex]

[tex]\frac{ds}{dt} =31.952[/tex]

Answer:

3 to 1

Step-by-step explanation:

its

Joe ate 7/30 more of pizza than Jane. You can just subtract 2 uneven denominators. So you would turn them into 30 because that’s the closest highest number that can go with 5 and 6. Then multiply 2 with 6 which is 12 and then multiply 1 with 5 which is 5 now you can subtract it. 12/30-5/30=7/30.

Final Result: 7/30

Answer:P(milk) 5/18 - 27% ----------- P(not milk) 13/18- 73%

Step-by-step explanation:

total chocolates in the bag= 18   (5 milk chocolates + 13 dark chocolates= 18 chocolates in total)

to find percentages divide numerator by denominator ( 5/18 = 27%) (13/18=73%)

P(milk) - 27% chance you will get milk chocolate

P(not milk) 73% chance you will get dark chocolate

It is more likey to get dark chocolate

The sun of the 3 inside angles of a triangle = 180 degrees.

A circle = 360 degrees.

The sum of both would be 180 + 360 = 540 degrees.

Answer:

3 angles in a triangle add up to 180

And 360 in a circle

[tex]\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}[/tex]

Two points are given to us and we need to find the slope of the line . The slope of the line passing through points [tex]\bf (x_1,y_1 ) \ \& \ (x_2,y_2) [/tex] is given by ,

[tex]\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}[/tex]

Here , the points are ,

[tex]\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}[/tex]

Answer:

Collette had 6 manicures done last year.

Step-by-step explanation:

Since Collette's mom has 67% more manicures than Collette (2 more for every 3), and that difference represented 4 manicures in total, then:

let x be the number of manicures that Collette had during last year.

4 / x = 2/3

2x = 12

x = 6

Answer:

50 minutes

Step-by-step explanation:

she spent 1 hr and 30 minutes on homework

she spends 2/3 of an hour on the phone = 40 minutes

1 hr 30 min + 40 minutes = 2 hrs and 10 min

so she had 50 minutes to kill before bedtime since she goes to sleep 3 hrs after dinner

2hr 10 min + 50 min = 3 hrs.

Answer:

I hope I got it correct

Step-by-step explanation:

The given question is incomplete. The complete question is :

One student did an experiment on the rock cycle.

The steps of the experiment are shown below.

Collect five pieces of wax of different colors.

Use a plastic knife to scrape off thin shavings of the pieces of wax.

Pile the wax shavings of different colors one over the other.

Hold the pile of wax shavings in the palm and squeeze it for two to three minutes. Fold the pile and squeeze it in the palm again for a minute.

What does the student's experiment most likely demonstrate about the rock cycle?

a. Weathering can change igneous rocks into sediments.

b. Weathering can change metamorphic rocks into sediments.

c. Heat and pressure can change igneous rocks into metamorphic rocks.

d. Heat and pressure can change sedimentary rocks into metamorphic rocks.

Answer: Option D

Explanation: The rock cycle defines the conversion or transformation of igneous rock into sedimentary rocks and sedimentary rocks into metamorphic rocks. The conversion of rocks into these three forms is continuous.

The igneous rocks on weathering forms sediments which on cementation and compaction gets converted into sedimentary rocks. Then sedimentary rocks under tremendous heat and pressure gets converted into metamorphic rocks.

These processes takes millions of years to gets converted from one rock form to another.

Here, in the experiment wax shavings of different colors one upon another shows that they are sedimentary rocks and pressing it between palm or hand shows that heat and pressure is applied on it. This shows the conversion of sedimentary rocks into metamorphic rocks.

Please give brainliest, thank me and rate it 5. :)

Answer:

x              y

0             2

2             6

4             10

6             14

I'll use the second one as the example.

First I found the x value because it was the value gaven to me, then I found the y value that lined up with it. Since the x value was 2, I had to go to the 2 on the x axis and went up until I got to the line, then I went horizontal until I hit the y axis and that's how I got 6 for the y value.

I hope this helped!!

Given:

The expression is

[tex]81x^4-1[/tex]

To find:

The factorized form of given expression.

Solution:

We have,

[tex]81x^4-1[/tex]

It can be rewritten as

[tex]=3^4x^4-1^2[/tex]

[tex]=(3x)^4-1^2[/tex]              [tex][\because a^xb^x=(ab)^x][/tex]

[tex]=((3x)^2-1)((3x)^2+1)[/tex]              [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

[tex]=(3x+1)(3x-1)(3x+1)(3x-1)[/tex]              [tex][\because a^2-b^2=(a-b)(a+b)][/tex]

This is the complete factorized form. It can also written as

[tex]=(3x+1)^2(3x-1)^2[/tex]

Therefore, the complete factorized form is [tex](3x+1)(3x-1)(3x+1)(3x-1)[/tex].
