D. [tex]\frac{1}{27}[/tex]

Step-by-step explanation:

[tex]3^{-3}[/tex] = [tex]\frac{1}{27}[/tex]. First you need to remove the negative exponent, to do this move the term into the denominator. [tex]\frac{3^{-3} }{1}[/tex] becomes [tex]\frac{1}{3^{3} }[/tex], then solve for [tex]3^{3}[/tex], which equals 27. So your answer is [tex]\frac{1}{27}[/tex].

There are two types of fish in a lake. These are carp and pike.
In a netted area of the lake 120 carp and 16 pike were caught
In the whole lake it is estimated there are 34 000 fish
Zalika estimated that there are 4000 pike in the lake altogether.
How does Zalika work out this estimate.​

Answers

Answer: Ratios

Step-by-step explanation:

Zalika can work out this estimate by using the ratio of carp to pike that she first caught. This is how to use the ratios:

1) 120 carp : 16 pike --> from given information

2) 136 fish : 16 pike --> add the numbers together to get total fish compared to pike

3) Multiply by 250 --> 34000 divided by 136 is 250

4) 34000 fish : 4000 pike --> 16x250=4000

If Alfonso does a job in 30 hours more than Zoe, and they can do the job together in 8 hours, how long would it take Zoe to do the job alone?​

Answers

Answer:

Step-by-step explanation:

Let the time it will take Alfonso be x

Let the time it will take Zoe be y

If Alfonso does a job in 30 hours more than Zoe, then;

x = 30+y...... 1

Also if they can do the job together in 8 hours, then;

x+y = 8.... 2

Substitute 1 into 2;

x+y=8

30+y+y = 8

40+2y = 8

2y = -32

y = -16

Hence X = 30-16

X = 14

y = 30+14 = 44

hence it will take Alfonso about 44hours to do the work alone

7 and 22

Step-by-step explanation:

The Sum of any Two Sides of a Triangle is Greater than the Third Side.

The third side = x

x < 8 + 15

x < 23

8 < x + 15

Can be any number in between 1 and 22.

15 < x + 8

Should be a number in between 7 and 22.

Step-by-step explanation:

The sides of a triangle are given as 3x, x - 1 and 3x + 1. If the perimeter [2]
is 56m find its sides.

Answers

Answer:

The sides are 24cm, 7cm, and 25cm

Step-by-step explanation:

3x+x-1+3x+1=56 <---- First we combine like terms (the 1's cancel out)

7x/7=56/7 <--- Divide by 7 to isolate the variable

x=8 <--- Now that we've solved for x we need to plug it back into each side

3(8)=24

(8)-1=7

3(8)+1=25

24+25+7=56 <---- Make sure it all adds up to 56

Hope this helps :)

Answer:

The sides of the triangle are:

[tex]3x = 3(8)=24[/tex][tex]x-1=8-1=7[/tex][tex]3x+1=3(8)+1=25[/tex]

Step-by-step explanation:

We know that the perimeter of a triangle is the sum of the length of its sides.

As the sides are given

3xx-13x+1

so the equation of the perimeter becomes

[tex]P=3x+\left(x-1\right)+\left(3x+1\right)\:[/tex]

as

P = 56m

so

[tex]56=3x+\left(x-1\right)+\left(3x+1\right)[/tex]

[tex]3x+x+3x-1+1=56[/tex]

[tex]7x-1+1=56[/tex]

[tex]7x=56[/tex]

[tex]\frac{7x}{7}=\frac{56}{7}[/tex]

[tex]x=8[/tex]

Now finding the sides

[tex]3x = 3(8)=24[/tex]

[tex]x-1=8-1=7[/tex]

[tex]3x+1=3(8)+1=25[/tex]

Therefore, the sides of the triangle are:

[tex]3x = 3(8)=24[/tex][tex]x-1=8-1=7[/tex][tex]3x+1=3(8)+1=25[/tex]

Eighteen 2.5 gallon buckets are needed to fill a cistern with water. Find the constant of variation. Please help! Thank you!

Answers

Given:

Eighteen 2.5 gallon buckets are needed to fill a cistern with water.

To find:

The constant of variation.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

Where, k is constant of variation.

In the given problem, water in cistern (w) is directly proportional to number of buckets (n).

[tex]w\propto n[/tex]

[tex]w=2.5n[/tex]        (Capacity of each bucket is 2.5 gallons)

Therefore, the constant of variation is 2.5.

The perimeter of a rectangle window is 226 cm. If the length of the window is 62 cm, what is its width?

Answers

Answer:

51 cm

Step-by-step explanation:

perimeter = 2 * length + 2 * width

226 = 2 * 62 + 2 * width

226 = 124 + 2 * width

226 - 124 = 2 * width

102  = 2 * width

102/2 = width

51 = width

Answers

Answer:

Thevalue of x-intercept is 0

and y intercept is-6.

Step-by-step explanation:

here,9x+6y=-36

9x = -36 - 6y

x=(-36 -6y)/9

x=(-12-2y)/9.........(i)

putting value of x in question

9[(-12-2y)/9]+6y=-36

-12-2y+6y= -36

-12+4y= -36

4y=-24

y=-6

puting value of x in equation (i)

x=(-12-2y)/9

x=(-12-2×-6)/9
