Simplify the expression 3^7/3^5

Answer:

Step-by-step explanation:

A proportion is being directly related to something, meaning that there is just multiplication or division (just a coefficient in front of the x-coordinate, nothing more).

In a graph, a proportional graph is a graph that goes straight through the origin.

Answer:

Step-by-step explanation:

The standard form of equation of a circle is expressed as;

x^2+y^2+2gx+2fy+c = 0

The centre is at (-g, -f)

Given the equation'

9x²+9y²+18x-12+10=0

Divide through by 9

9x²/9+9y²/9+18x/9-12y/9+10/9=0

x^2+y^2+2x-4/3 y + 10/9 = 0

Compare

2gx = 2x

g = 1

2fy = -4/3 y

2f = -4/3

f = -4/6

f = -2/3

The centre is (-(-2/3), -1) = (2/3, -1)

for the radius

r = √f²+g²-c

r =√(-2/3)²+1²-10

r =√4/9 - 9

r = √(4-81)/9

r = √-77/9

Actually Welcome to the Concept of the linear Equations.

To solve this, lets consider,

Lets consider basic hits of Ricky to be 'x' and that of pedro be x + 283 ,

hence we get as,

x + (x+283) = 2673

===> 2x = 2673 - 283

===> 2x = 2390

==> x = 1195

hence, Ricky has 1195 basic points and pedro has 1478 basic hits.

Answer:

pedro = 1478 ricky 1195

Step-by-step explanation:

2673 - 283 = 2390

2390 divided by 2 equals 1195

1195 + 283 = 1478

1478 + 1195 = 2673

Answer:

Step-by-step explanation: this is true because for 4.89 you would just add a 0 to make it 4.890

Answer:

Value of the car at the end of 3 years is £7917.75

Step-by-step explanation:

The car is purchased for £11500.

In the first year, 15% depriciation.

So, depreciation on first year =11500 *[tex]\frac{15}{100}[/tex] =1725

After first year depreciation the value of car =11500-1725 =£9775

Now, second year depreciation is 10%

So, 10% of 9775 =0.10*9775 =977.5

Value of car after 2 years = 9775 -977.5 =8797.5

Now, for third year depreciation is 10%.

So, depreciation on 3 year = 10% *8797.5

                                           =0.10*8797.5

                                          =879.75

So, value of car after 3 years = 8797.5 -879.75 =£7917.75

Answer:

$12

Step-by-step explanation:

We are told that there are 20 people in the chess club and each got a discount of $60 for transportation on the field trip.

Let the amount spent by each member is x

Since there are 20 of them and the budget is at least $300 and they get a discount of $60, it means that;

20x ≥ 300 - 60

20x ≥ 240

Divide both sides by 20 to get;

x ≥ 12

Thus, minimum amount each member can spend is $12.

We already have our first value 120 and the second value 72. Let's assume the unknown value is Y which answer we will find out.

As we have all the required values we need, Now we can put them in a simple mathematical formula as below:

Y = [tex]\frac{72}{120}[/tex]

By multiplying both numerator and denominator by 100 we will get:

Y = [tex]\frac{72}{120}[/tex] × [tex]\frac{100}{100}[/tex] = [tex]\frac{60}{100}[/tex]

Therefore, we get y = 60

You can also find percent of 120 is 72, just by entering 72 ÷ 120 × 100 and you will get your answer which is 60.

Acute angle

Step-by-step explanation:

because it less than 90 degree so it possible to be acute triangle

Answer:

She made 80 total cookies because 25% of 64 is 16. 64 plus 16 is 80. You are adding the original amount(60) to 25%(16).

Answer:

First find out the other side measurements. Then split the shape into seperate squares and find the area then add them all up.

Step-by-step explanation:

volume is length × width × height.

Answer:

240 cm cubed

Step-by-step explanation:

If you separate the shape into 2 figures, the first figures area is 180

and the second is 60.

180 + 60 = 240

Hope this helps!

Answer:

268

Step-by-step explanation:

The volume formula for a sphere is: V= [tex]\frac{4}{3}\pi r^{3}[/tex]

We also know that [tex]\pi[/tex] is approximately 3.14.

You have to know these in order to solve the question..

Since we also know the diameter is 8 we can also find the radius (r) ,which is half of the diamater so 4.

Now all we need to do it plug in the numbers.

V= [tex]\frac{4}{3}[/tex](3.14)[tex]4^{3}[/tex]

Now solve for the equation.

V=267.94...

So rounded that is 268.

Answer:

x = 24.25 inches

Step-by-step explanation:

sin 60 = 21/x

0.866 = 21/x

x = 24.25

Answer:

24 (if its supposed to be rounded to whole)

24.2 (if rounded to tenth)

Step-by-step explanation:

Sin a= opp/hyp

opp=21

hyp=x

a=60

Sin60=21/x

Get x to the other side by multiplying on both sides

x*sin60=21

Now divide by sin60 on both sides

x=21/sin60

Find sin60

sin60=0.866025...

divide 21 by 0.866025

21/0.866025=24.248722....

So rounded to the nearest 10th is 24.2

Rounded to nearest whole is 24

Answer:

The savings interest rate of Nakato Nobuki is 3 %

Step-by-step explanation:

Given;

Final amount of Nakato Nobuki, A = $ 24,000.00

time period of his investment, t = 5 years

principla amount, P = $ 1,500.00

The savings interest rate of Nakato Nobuki can be calculated on a simple interest basis.

A  = P(1 + rt)

r is the savings interest rate

Substitute the given values and solve for r

24,000 = 1,500(1 + 5r)

24,000 = 1,500 +  7,500r

7,500r = 24,000 - 1,500

7,500r = 22,500

r = 22,500/7,500

r = 3 %

Therefore, the savings interest rate of Nakato Nobuki is 3 %

Answer:

No, it's not linear function.

Step-by-step explanation:

The x value repeatedly adds 3.

So far its a linear function.

If you look at the y value, it does NOT have a pattern, therefore that means it is NOT a linear function.

Answer:

- 5

Step-by-step explanation:

let the number be n then double is 2n , so

2n + (- 6) = - 16

2n - 6 = - 16 ( add 6 to both sides )

2n = - 10 ( divide both sides by 2 )

n = - 5

The number is - 5

Answer:

53°

Step-by-step explanation:

ΔABC is a right triangle (one of the angles is 90°).

You can use SOH-CAH-TOA to find an angle:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

In this case, we want to find ∠A.  We know the lengths of the opposite side and the hypotenuse.  Therefore, we should use sine.

sin A = 12 / 15

m∠A = sin⁻¹(12/15)

m∠A ≈ 53°

Alternatively, you could use Pythagorean theorem to find the third side, then use either cosine or tangent to find m∠A.

Answer:

53

Step-by-step explanation:
