Seventh-graders = 18

18/36*100 = 50%

Answer:

Step-by-step explanation:

12 are 6th graders

18 are 7th graders

6 are eight graders

total=36

7th graders are 50%

18........................?%

Answer:

x = 9.9   (or √98) (or 98¹/²)

y = 7

Step-by-step explanation:

triangle is equilateral right triangle, y = 7

x² = 7² + 7² = 98

x = 9.9   (or √98) (or 98¹/²)

Answer:

2000.000000000000000000

Answer:

r≈24

Step-by-step explanation:

The radius is 23.999999545959  but once rounded to the nearest whole number that is 24

Subtract sin (8x − 10) from both sides of the equation.

cos (6x − 12) − sin (8x − 10) = 0

Answer:

It doesn't exist

Step-by-step explanation:

since :

cos (90° – x) = sin x

cos(x) = sin(pi/2 - x)

then

cos(6x-12) =! sin(8x-10)

since (8x-10) =! (pi/2- 6+12)

then this identity of cos(6x-12) = sin(8x-10) doesn't exist

Answer:

x=22 y= 46

Step-by-step explanation:

2-24 2-48

Answer:

Equations are :---

[tex]3x - 2y = 24............... (i) \\ x + 2y = 48..................(ii)[/tex]

By adding the both equations we get,

[tex](3x - 2y) + (x + 2y) = 24 + 48 \\ 4x = 72 \\ x = \frac{72}{4} \\ \boxed{ x = 18} \\ [/tex]

Putting the value of x in equation (ii) we get

[tex]18 + 2y = 48 \\ 2y = 48 - 18 \\ 2y = 30 \\ y = \frac{30}{2} \\ \boxed{y = 15}[/tex]

Answer:

16 rides

Step-by-step explanation:

If he has $12 in total and each ride costs 75 cents, you can divide 12 by .75 to find how many rides he can go on.

12/0.75 = 16

Answer:

200

Step-by-step explanation:

Given that :

Slope intercept equation :

y=200x+10000

The number of spots being added per year is the value of slope in the equation ;

The general form of a slope intercept equation is :

y = mx + c

Where m = slope

Comparing the equation given to the general formula ; m corresponds to 200 ; hence number of spots added per year = 200

Answer: Andre

Step-by-step explanation: coz I juss know..

Answer:

Andre

Step-by-step explanation:

This situation can be modeled with the equations:

A = 100 + 5w

E = 10 + 20w

Let w represent the number of weeks that have passed since they have started saving money. Andre(A) has saved $5 per week and Elena(E) has saved $20 per week. Substituting 4 into the equation (because 4 is the number of weeks that have passed so far) and evaluating we come to the realization that Andre still has more money than Elena because he now has $120 and Elena has $90.

Answer:

16/14= 8/7 = lauren/ cara

8x+7x= 1200

15x= 1200

x= 1200/15

Answer:

2x^9 x

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "x3"   was replaced by   "x^3".  

STEP  1 :

Multiplying exponential expressions :

1.1    x4 multiplied by x3 = x(4 + 3) = x7

The Equation at the end of step  1 :

 ((2x7 • x) • x) • y

STEP  2:  Final result :

 2x^9 y

Answer:

  B)  Dilations increase angle measures.

Step-by-step explanation:

Dilations have no effect on angle measures, but they uniformly change the size and spacing of line segments. They are a non-rigid transformation that leaves geometric figures similar to the original.

The false statement is B.

Answer:

Step-by-step explanation:

1 - a

2 - c

3 - b

Answer:

Step-by-step explanation:

To solve this, we would use the formula for calculating simple interest which is:

Interest = PRT

Then, we will slot in the values given which will be:

84 = P × 3% × 7

84 = P × 0.03 × 7

84 = 0.21P

P = 84/0.21

P = $400

The Principal is $400

Step-by-step explanation:

n= nickels

q= quarters

Create a system of equations

n + q =72 number of coins

0.05n + 0.25q = 12 amount in money

solve by elimination ( anything would be fine)

n + q = 72

4( 0.05n + 0.25q = 12)

n+ q = 72

-

0.2n + q = 48

0.8n = 24

n= 30

now use substitution to find how many quarters she has

30 + q = 72

q = 42

He has 30 nickels and 42 quarters
