Which table goes with the graph?

Answer:

81

Step-by-step explanation:

square root of 729= 9

9×9=81

Answer:

Step-by-step explanation:

Formula of Volume= [tex]a^{3}[/tex] - a = side

Therefore since the volume is given you just need to find the side.

729=[tex]a^{3}[/tex] = [tex]\sqrt[3]{729}[/tex] = a

            = 9 = a

Now you know that 9 is the side, so using that find the area of one face-

Area of a square= 9 x 9 = 81[tex]cm^{2}[/tex]

Polynomial = (2x² - x + 3)(x - 2) + 4 = 2x³ - 5x² + 5x - 2. (B)

Answer: Angle 2 and Angle 8

:)

Step-by-step explanation:

Answer:

2 and 8

Step-by-step explanation:

Answer:

the first one is 1.935843 x 10^6

the second one is 4 x 10^7

subtract the two numbers in each question

convert to scientific notation:

if the number is 40,000,000 the scientific notation would be 4 x 10^7 because there are 7 spaces behind the first digit, or the 4

Answer:

y = x+5 where y is Mark's age

Step-by-step explanation:

Hi there, to answer this problem, you need to really think about what it is asking. In saying that mark is 5 years older than Juan, we know it is going to involve addition. Then, you simply need to think about the relation to Juan's age. In this case, Mark is older so you add to it. Hope this helped!

To find:

Which of the following options is an equation.

Solution:

A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.

In option A,

[tex]5-4=9[/tex]

[tex]1\neq 9[/tex]

LHS≠RHS. So, it is not an equation.

In option B and C,

[tex]5+4=9[/tex]

[tex]9=9[/tex]

LHS=RHS. Both are equations.

In option D,

[tex]5+4-9[/tex]

This is an expression, not an equations.

Therefore, the correct options are B and C.

Step-by-step explanation:

4.03834

1dp) 4.0

2dp) 4.04

3dp) 4.038

24.8845

1dp) 24.9

2dp) 24.88

3dp) 24.885

0.62346

1dp) 0.6

2dp) 0.62

3dp) 0.623

2.3999

1dp) 2.4

2dp) 2.40

3dp) 2.400

1 d.p:

4.03834 = 4.0

24.8845 = 24.9

0.62346 = 0.6

2.3999 = 2.4

The 1 d.p is the first number after the decimal point and to write it as 1 d.p you need to round it off.

2 d.p:

4. 03834 = 4.04

24.8845 = 24.88

0.62346 = 0.62

2.3999 = 2.40

The 2 d.p is the second number after the decimal point.

3 d.p:

4.03834 = 4.038

24.8845 = 24.885

0.62346 = 0.623

2.3999 = 2.400

The 3 d.p is the third number after the decimal point.

Step-by-step explanation:

Area of the border = Length * Breadth

If the outside measures 10in by 11in with 1-in border, the length of the picture with border = 10+(1+1) * 11+(1+1)

Area of the border = 12*13

Area of the border = 156in²

Note that the border length will be added at both edges of the frames for each length and the width of the frame

Answer:

38

Step-by-step explanation:

Answer:

a: given

b: multiplication property of equality

c: distributive property

d: simplified

e: addition property of equality

f. division property of equality

Step-by-step explanation:

step a will always be given because it is starting equation. step b is multiplication property because everything is multiplied by two so you don't have to deal with decimals. step c is distributive because you distribute the -5s in the parentheses. step d is simplified because they combined like terms and nothing changed sides. step e is addition property because you added 5x to both sides. step f is division property because -7 is divided from each side.

Answer:

(-0.5, 0)

Step-by-step explanation:

'B' lies on the x-axis. This means that it's y-value is zero.

'B' also is in between '-1' and '0'. This means that the x-value is -0.5.

'B' should be (-0.5, 0).

Hope this helps.

Answer:

[tex]\frac{3}{16}[/tex]

Step-by-step explanation:

We do the division first because of PEMDAS.

Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

Therefore,

[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]

Multiply the two fractions:

[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]

[tex]\frac{5}{8}-\frac{7}{16}[/tex]

The LCM of the denominators (8 and 16) is 16.

Adjust fractions:

[tex]\frac{10}{16}-\frac{7}{16}[/tex]

Subtract:

[tex]\frac{10-7}{16}[/tex]

[tex]\frac{3}{16}[/tex]

Greetings from Brasil...

Let's add all the values on one side and make it equal to the sum of all the other values on the other side

(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1  =  X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)

- 5X + 12 = 3X - 8

- 5X - 3X = - 8 - 12

- 8X = - 20    x(- 1)

8X = 20

X = 20/8

Answer:

w=15

Step-by-step explanation:

Just plug -2 into x

f(-2) = 2(-2)^2 + 4(-2) + 5

Simplify the right side

f(-2) = 8 - 8 + 5

Combine like terms

f(-2) = 5

Answer: h(-5) = -15

Step-by-step explanation:

h(-5)= 2(-5) -5  

h(-5)= -10-5

Assuming the side of the rectangle are (L) length and (W) width, the perimeter:

2L + 2W = 234

:

"the rectangle is twice as long as it is wide,", the equation for this statement:

L = 2W

:

In the first equation, we can replace L with 2W, then we have

2(2W) + 2W = 234

4W + 2W = 234

6W = 234

Divide both sides by 6

W = 234%2F6

W = 39 meters is the width

:

Remember it said the length is twice the width, therefore:

L = 2(39)

L = 78 meters is the length

:

:

Check this by finding the perimeter with these values

2(78) + 2(39) =

156 + 78 = 234

Answer:

B) Their y-coordinates are the same.

Step-by-step explanation:

P is at (-6,4)

Q is at (1,4)

Their y-coordinates are the same.

Answer:

Tommy's band won 5 awards, Ali's band won 8 awards and Jack's band won 10 awards.

Step-by-step explanation:

Let the number of awards Tommy won be x.

Number of awards Ali won -> x+3

Number of awards Jack won -> 2x

[tex]x+x+3+2x=23[/tex]

[tex]4x+3=23[/tex]

Subtract 3 from both sides:

[tex]4x+3-3=23-3[/tex]

[tex]4x=20[/tex]

Divide both sides by 4:

[tex]\frac{4x}{4}=\frac{20}{4}[/tex]

[tex]x=5[/tex] (Tommy)

[tex]5+3=8[/tex] (Ali)

[tex]5\times2=10[/tex] (Jack)

Answer: Tommy won 5 awards. Ali won 8 awards. Jack won 10 awards.

Step-by-step explanation:

First give each person a variable:

Tommy = y

Ali = a

Jack = x

Then figure out the equations:

Tommy won 3 less awards than Ali, so the equation would be (y = a - 3).

Jack won twice as many awards as Tommy, so the equation would be (x = 2y)

All three won a total of 23, so that would be (23 = y + x + a)

Next, plug in (2y) into the (x) of (23 = y + x + a)

This would result in (23 = 3y + a)

Then you would plug in (a - 3) into (y)

This would result in (23 = 4a - 9)

Solve for a: (a = 8)

Now that you know (a = 8), plug that into the first equation (y = a - 3) to find (y).

Answer: (y = 5)

Use (y = 5) and plug it into the second equation (x = 2y) to find (x)

Answer: (x = 10)

Answer:

Happy paws

y = 20 + 4x

Woof watchers

y = 9 + 5x

x = 11 hours

Step-by-step explanation:

Let

Number of hours = x

Total cost = y

Total cost = fixed cost + variable cost

The equations are:

Happy paws

y = 20 + 4x

Woof watchers

y = 9 + 5x

solve the equation to find for how many hours the total cost of the services is equal.

Equate total cost of both services

20 + 4x = 9 + 5x

Collect like terms

20 - 9 = 5x - 4x

11 = x

x = 11 hours

Check:

Happy paws

y = 20 + 4x

= 20 + 4(11)

= 20 + 44

= 64

Woof watchers

y = 9 + 5x

= 9 + 5(11)

= 9 + 55

= 64
