What percent of 4600% is 2530

Answer:

C) 2744 cm

Step-by-step explanation:

To find the volume of a cube you have to use this equation:

V = a^3

Now plug in the number:

V = 14^3

14^3 or 14*14*14 = 2,744

The volume is 2,744 cm

Answer:

1) 2744cm^3

2)1176cm^2

Step-by-step explanation:

1)Since it's a square, the sides are all equal length. And volume=base×width×height

thus we can multiply 14×14×14=14^3=2744cm^3

2)for surface area we can find the area of on side and multiply it by 6 because the square has six equal sides. thus, area=base×height so, area=14×14=14^2=196cm^2

Now we multiply it by 6 which is equal to 1176cm^2

Answer:

Step-by-step explanation:

8.

Let Dylan have d, Mike have m, and Jeremy have j

3 of them have 171, so we can write:

1. [tex]d + m + j = 171[/tex]

Mike has twice as Dylan, so we can write:

2. m = 2d

Jeremy had three times as Mike, so:

3. j = 3m

We can write equation 3 as m = j/3

Also, if we put this into equation 2, we have:

j/3=2d

d=j/6

Now we have d and m in terms of j. We put it into equation 1 and solve for j:

[tex]\frac{j}{6} + \frac{j}{3} + j = 171\\\frac{3j+6j+18j}{18}=171\\\frac{27j}{18}=171\\27j=18*171\\27j=3078\\j=\frac{3078}{27}\\j=114[/tex]

amount of stamps Maddy has is m and amount Simon has is s

Maddy had twice as many stamps as Simon:

m = 2s

Also

After Maddy sold 60 stamps, Sinom had twice as many stamps as Maddy:

s+60=2(m-60)

We put the first equation in the second and solve for s:

s+60=2(m-60)

s+60=2(2s-60)

s+60=4s-120

180=3s

s=60

THus, m = 2(60) = 120

So maddy had 120 - 60 = 60 more stamps than Simon

Answer:

Part 1) The equation tells us that Terry started at an elevation of 2,600 ft

Part 2) The elevation is decreasing by 50 feet each second

Step-by-step explanation:

we have

[tex]E(t)=2,600-50t[/tex]

where

E(t) is Terry's elevation in feet

t is the time in seconds

Part 1) Find the E intercept of the equation

The E-intercept is the value of E when the value of t is equal to zero

so

For t=0

substitute

[tex]E(0)=2,600-50(0)[/tex]

[tex]E(0)=2,600\ ft[/tex]

therefore

The equation tells us that Terry started at an elevation of 2,600 ft

Part 2) Find the slope of the equation

we have

[tex]E(t)=2,600-50t[/tex]

This is the equation of the line into slope intercept form

The slope m is equal to

[tex]m=-50\ ft/sec[/tex]

The slope is negative, because is decreasing

therefore

The elevation is decreasing by 50 feet each second

The subject of this question is Physics. The given equation represents Terry's elevation while skiing down a steep hill.

The subject of this question is Physics. The given equation E(t) = 2600 - 50t represents Terry's elevation in feet after t seconds while skiing down a steep hill.

To better understand the equation, let's break it down step-by-step:
- The constant term 2600 represents Terry's initial elevation at t = 0 seconds.
- The coefficient of t, -50, represents the rate at which Terry's elevation decreases as time passes. This means that Terry's elevation decreases by 50 feet for every second that goes by.

Based on this equation, Terry's elevation will progressively decrease as time passes.

[tex]\sin \frac{3\pi}{2} = -1[/tex]

[tex]\cos\frac{3\pi}{2} =0[/tex]

Step-by-step explanation:

Please refer to the image attached.

Here we have a circle with unit radius. At some angle Ф the radius = 1 , and it is the hypotenuse (shown by green line in the image attached) of the ΔPQR thus formed. As our angle  Ф increases, the hypotenuse gets closer to the positive y axis and at 90°, it overlap the y axis. Hypotenuse (H) and Opposite site (O) becomes same and Adjacent (A) becomes 0.

As our angle move further and reaches 180, the Hypotenuse and adjacent becomes same and overlap negative x axis. As we move further at 270 i.e [tex]\frac{3\pi}{2}[/tex] , the hypotenuse and opposite side overlap on y axis and Adjacent side become 0. However the opposite side becomes negative here .

Our sine ratio says

[tex]\sin \frac{3\pi}{2} =\frac{opposite}{Hypotenuse}[/tex]

[tex]\sin \frac{3\pi}{2} =\frac{-1}{1}[/tex]

[tex]\sin \frac{3\pi}{2} =-1[/tex]

Hence we have our [tex]\sin \frac{3\pi}{2} = -1[/tex]

Now

[tex]\cos\frac{3\pi}{2} =\frac{Adjacent}{Hypotenuse}[/tex]

Adjacent as we discussed is 0 at [tex]\frac{3\pi}{2}[/tex]

[tex]\cos\frac{3\pi}{2} =\frac{0}{1}[/tex]

Answer:

1873

Step-by-step explanation:

just add them up

The restaurant sold a total of 1837 orders of eggs.

To calculate the total number of orders of eggs sold by the breakfast restaurant, we need to add up all the individual orders for each type of eggs.

Scrambled eggs: 889 orders

Poached eggs: 313 orders

Fried eggs: 594 orders

Hard-boiled eggs: 41 orders

Now, let's add these numbers together:

889 + 313 + 594 + 41 = 1837 orders

Therefore, the restaurant sold a total of 1837 orders of eggs.

Answer:

Length of larger piece: 7 m

Total length of carpet is: 19 m

Step-by-step explanation:

Let the smaller piece have length x.

Let the larger piece have length y.

"The length of the smaller piece is 5 meters greater than the length of the larger piece."

x = y + 5

"If the length of the smaller piece is 12 meters"

x = 12

x = y + 5

12 = y + 5

7 = y

y = 7

The larger piece has length 7 meters.

The total length of the carpet is x + y = 12 m + 7 m = 19 m

To find the length of the larger piece of carpet, use the equation x + 5 = 12, and solve for x. Substitute the total length of the carpet for x in the formula to find the length of the larger piece.

The problem involves finding the length of the larger piece of carpet when the length of the smaller piece and the total length of the carpet are known. Let's assume the length of the larger piece is x meters. According to the problem, the length of the smaller piece is 5 meters greater than the length of the larger piece, so the length of the smaller piece can be represented as x + 5 meters. The total length of the carpet is the sum of the lengths of the smaller and larger pieces, so we can create the equation: x + (x + 5) = total length. Given that the length of the smaller piece is 12 meters, we can substitute x + 5 with 12 in the equation and solve for x:

x + (x + 5) = total length

x + x + 5 = total length

2x + 5 = total length

2x = total length - 5

x = (total length - 5) / 2

Now we have the formula to calculate the length of the larger piece. Simply substitute the total length of the carpet into the formula to find the length of the larger piece.

Answer:

temperature of city a=5

temperature of city b=4

Step-by-step explanation:

Given:

Let temperature of city A= a

temperature of city B=b

As given:

4a=8+3b

a-2b=-3

rearranging 2nd equation we get:

a=-3+2b

substituting above in 1st equation we get:

4(-3+2b)-3b=8

8b - 12 = 3b + 8

8b-3b=12+8

5b = 20

b = 4

Now substituting b=4 in 4a = 8 + 3b , we get

4a = 8 + 3b

4a = 8 + 3(4)

4a = 8 + 12

4a = 20

a = 20/4

a = 5

temperature of city a and city b on that day is 5C and 4C respectively!

Answer:

The temperature of the city a was 5 °C and b was 4 °C.

Step-by-step explanation:

First we have to write the equations based on the description, this is:

[tex]4a=8+3b\\a-2b=-3[/tex]

Now that we have the equations, we can replace the second in the first:

[tex]4(2b-3)=8+3b[/tex]

Now we can find the value of b:

[tex]8b-12=8+3b[/tex]

[tex]8b-3b=8+12[/tex]

[tex]5b=20[/tex]

[tex]b=\frac{20}{5}[/tex]

[tex]b=4\\[/tex]

Now with the value of b and the second equation we can get the value of a:

[tex]a-2(4)=-3[/tex]

[tex]a-8=-3[/tex]

[tex]a=8-3[/tex]

[tex]a=5[/tex]

The temperature of the city a was 5 °C and b was 4 °C.

a(8)=12582912

Step-by-step explanation:

The 8th term can be determined by the formula:

an = a1 * r^(n-1)

where

n = the term to be found = 8

a1 = 1st number

r = common ratio

Common ratio can be found by dividing the second term by the first term

= 48/6 = 8

Substitute the values in the formula

a(8) = 6 * 8^(8-1)

a(8) = 6 * 8^7

a(8)= 6*8*8*8*8*8*8*8

a(8) = 6 * 2097152

a(8)=12582912 ....

Therefore the 8th term is 12582912 ....

Answer:

Answer:

The x-intercepts are (4,0) and (-1/3,0).

Step-by-step explanation:

f or any relation/function will intersect the x-axis when y is 0.

Set that's what we will do is set y to 0 and solve for x.

0=3x^2-11x-4

I'm going to attempt to factor.

a=3

b=-11

c=-4

We need to find two numbers that multiply to be ac and add up to be b.

ac=-12=-12(1)

b=-11=-12+1

Let's factor 3x^2-11x-4 by grouping.

3x^2-11x-4

3x^2-12x+1x-4       ; I replaced -11x with -12x+1x

Group the first 2 pairs and group the last two pairs like so:

(3x^2-12x)+(1x-4)

Now factor what you can from each pair:

3x(x-4)+1(x-4)

Now you have two terms, both with the common factor (x-4) so factor it out:

(x-4)(3x+1)

Now let's go back to solving:

3x^2-11x-4=0

This is the same as solving:

(x-4)(3x+1)=0  (because this is just the factored form of the original equation.)

Now this means either x-4=0 or 3x+1=0.

We need to solve both.

x-4=0 can be solved by adding 4 on both sides resulting in x=4.

3x+1=0 requires two steps.

3x+1=0

Subtract 1 on both sides:

3x=-1

Divide both sides by 3:

x=-1/3
