What is the value of a if a is equal to a×a×a=a+a+a

Answers

Answer:

a = ±sqrt(3)

Step-by-step explanation:

a×a×a=a+a+a

Simplifying each side

a^3 = 3a

Divide each side by a

a^3 /a = 3a/a

a^2 = 3

Take the square root of each side

sqrt(a^2) = ±sqrt(3)

a = ±sqrt(3)

Answer:

nope its not equal

a×a×a=a³, but a+a+a=3a

so, a³≠3a

Anton has 3 8/7​ cups of syrup that he serves with his pancake orders. He uses 2/3 cup of syrup for each pancake order. What is the maximum number of complete pancake orders that Anton can serve with the syrup he has?

Answers

Answer:

6 3/14 pancake order s

Step-by-step explanation:

The question above is calculated as:

2/3 cup of syrup = 1 pancake order

3 8/7 cups of syrup = x

Cross Multiply

2/3 × x = 3 8/7 × 1

x = 3 8/7 ÷ 2/3

x = 29/7 ÷ 2/3

x = 29/7 × 3/2

x = 87/14

x = 6 3/14 order

The maximum number of complete pancake orders that Anton can serve with the syrup he has is 6 3/14 pancake orders

Answers

Complete question is;

A group of biologists is surveying the mice population in a forest. The equation n=75⋅3t gives the total number of mice, n, t years since the survey began.

what does the number 3 mean in this situation.

1. the common difference

2. the total population

3. the common ratio

4. the slope

Answer:

3 is the common ratio

Step-by-step explanation:

We are given that the equation; n = 75⋅3^(t) gives the total number of mice, n, t years since the survey began.

Normally, formula when calculating population growth takes an exponential function;

n = n_o(e^(rt))

Or in this our case, it can be written as;

n = n_o((e^(r))^(t))

Comparing this with n = 75⋅3^(t), we can see that e^(r) = 3

Where r is the growth rate.

e is exponential constant.

Thus, we can say that 3 is the common ratio

Gary Sanchez struck out 112 times in 350 at bats. What PERCENTAGE of his at-bats were strike outs?

Answers

Given :

Gary Sanchez struck out 112 times in 350 at bats.

To Find :

Percentage of his at-bats were strike outs.

Solution :

We know, percentage hits is given by :

[tex]Percentage = \dfrac{\text{Number of time bats were strike out}}{\text{Total number of bats}}\times 100 \ \%[/tex]

Putting all given values in above equation, we get :

[tex]Percentage = \dfrac{112}{350}\times 100\ \%\\\\Percentage = 32\ \%[/tex]

Hence, this is the required solution.

Answers

Answer:

16

Step-by-step explanation:

The variable a minus 10 equals 6. If you substituted a for 16, and subtracted 10, you'd get 6. Substituting the rest of the numbers and subtracting 10 wouldn't give you 6.

a - 10 = 6
in order to find a, you want to get a alone by itself.
to do that you add 10 to both sides because it can never be just one side
then that will give you a= 10 + 6
which is then a = 16

so your answer is 16

The circumference of a circular tablecloth is 160 inches, Will the tablecloth cover
a table with diameter 52 inches?

Answers

Answer:

D= 50.92 in

Step-by-step explanation:

Step one:

Given data

The circumference of a circular tablecloth is 160 inches

We want to know if the circular table cloth can also cover a table of diameter 52 in

Step two:

let us solve for the diameter of the table cloth given that the circumference is

160in

circumference

[tex]C= 2 \pi r[/tex]

[tex]160= 2*3.142*r\\\\160= 6.284r[/tex]

divide both sides by 6.284

[tex]160/6.284= r\\\\r=25.46 in[/tex]

The diameter of the table cloth is

[tex]=25.46*2\\\\=50.92 in[/tex]

The Table cloth cannot cover the table because the diameter of the cloth is not up to the diameter of the table

Answers

Answer:

Me and my massive brain, among other massive things of mine, believe it to be -1

Step-by-step explanation:

The value of the function F(g(x) will be equal to (7 / 2).

What is a function?

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Given functions are:-

f(x)=3x-7 g(x)= x +(1/x-1)

The function F(g(x) is written as :-

F(g(x) = 3 [ x + ( 1 / ( x-1 )) -7 ]

F(g(x) = 3 [ (3 + (1/2) - 7 ]

F(g(x) = 3 (7 / 2 ) -7

F(g(x) = ( 21/2) - 7

F(g(x) = ( 21-14 ) ( 2 )

F(g(x) = ( 7/2 )

Therefore the value of the function F(g(x) will be equal to (7 / 2).

In AWXY, X = 1.2 cm, ZX=45° and Y=108°. Find the length of w, to the nearest 10th

Answers

Answer:

The length of w is 0.8 cm

Step-by-step explanation:

In Δ WXY

x is the opposite side to ∠X

w is the opposite side to ∠W

y is the opposite side to ∠Y

∵ m∠X = 45°

∵ m∠Y = 108

∵ The sum of the measures of the interior angle of a triangle is 180°

45 + 108 + m∠W = 180

→ Add the like terms in the left side

∵ 153 + m∠W = 180

→ Subtract 153 from both sides

m∠W = 27°

Now we can use the sine rule to find the length of w

∵ [tex]\frac{w}{sin(W)}[/tex] = [tex]\frac{x}{sin(X)}[/tex] = [tex]\frac{y}{sin(Y)}[/tex]

→ Use the first 2 ratios to find w

∵ x = 1.2 cm

∵ [tex]\frac{w}{sin(27)}[/tex] = [tex]\frac{1.2}{sin(45)}[/tex]

→ By using cross multiplication

w × sin(45) = 1.2 × sin(27)

∴ w sin(45) = 1.2 sin(27)

→ Divide both sides by sin(45)

w = 0.7704474263

→ Round it to the nearest tenth

w = 0.8 cm

The length of w is 0.8 cm

Declan wants to mail 28 drawings to his Grandma. If he can fit 3 drawings in each envelope, how many envelopes will he need to mail all the drawings

Answers

Answer: 10 envelopes

Explanation: 28÷3=9.33
Now, I am assuming you can't have 9 1/3 envelopes, so I rounded up (which makes the answer 10).

Answer:

10 envelopes

Step-by-step explanation:

What we know:

- There are 3 drawings for each envelope

- There are 28 drawings in total

To find out the number of envelopes Declan would need, we divide 28 by 3 (check the picture attached).

28÷3=9 R1

28 divided by 3 gives us 9 with a remainder of 1, which means if Declan had 9 envelopes, he would be able to fit 3 drawings in each with 1 drawing left over. He would need a 10th envelope to use for the last drawing.

Therefore, Declan would need 10 envelopes to mail all the drawings to his grandma.
