Answer: D. 120 students

Step-by-step explanation:

This is an easy solution

Take 300 and divide it by 5

300/5

This will result in 40

Now Multiply 40 by 3

Like so: 40x3

This will result in 120

Answer:

C) 120

Step-by-step explanation:

Ratio - 3:5

200 times 3/5 = 120

Answer:

No

Step-by-step explanation:

5 to the power of -1 is 0.2 while 5 to the power of 1/2 is 2.5

Answer:

0.375

that's what comes up for me

Answer:

0.375 or 3/8

Step-by-step explanation:

Calculator or

12/32 can be simplified by dividing both the numerator and denomenator by 4. Or with long division you can get 0.375.

Answer:

900g

Step-by-step explanation:

This is a case of direct variation as the weight will increase with the number of toys.

hence, 4/600 = 6/x

4x = 3600 (cross multiplication)

x = 900

Hence the weight of 6 such toys is 900g.

The first one is a the second one is b

Step-by-step explanation:

Answer:

The correct answer is A

Step-by-step explanation:

Answer:

Part A: 8(a+2c)

Part B: -56

Answer:

y=-2x+4

Explanation:

Subtract 6x from both sides of the equation.

3y=12−6x

Divide each term by 3 and simplify.

Divide each term in 3y=12−6x by 3.

Cancel the common factor of 3.

Answer:

I believe the answer is D: 300 inches

Step-by-step explanation:

This might be incorrect, but here's how I see the answer:

First I found the perimeter of one square.

2 + 3 = 5^2= 10

10 inches is the perimeter of one square.

Then, since there is 30 rectangles, and each perimeter is 10 inches long, then you would simply need to multiply the two numbers.

30 * 10 = 300 inches of red thread will be needed.

Answer:

300 in

Step-by-step explanation:

2+2+3+3 = 10

Perimeter 10 for one rectangle.

Multiply 10 by 30 to find out the total perimeter for 30 rectangles.

10 x 30 = 300

Answer:

95 in.²

Step-by-step explanation:

Total surface area of the rectangular pyramid = 4(area of triangle) + area of rectangle

Area of triangle = ½*base*height

base = 5 in.

height = 7 in.

Area of triangle = ½*5*7 = 17.5 in.²

Area of rectangle = Length*width = 5*5 = 25 in.²

Plug in the values

Total surface area of the rectangular pyramid = 4(17.5) + 25

= 95 in.²

Step-by-step explanation:

m= d * v

d= 3

v= 5 * 5 * 5= 125

125 * 3 = 375

Answer:

The equation is;

y = 1/3x

Step-by-step explanation:

The equation of a linear model is given as;

y = mx + b

m is the slope while b is the y intercept

As we can see, the y intercept is the origin and that means b is zero

To get the value of m, the slope, we have to use the slope equation

We simply select any two points on the line

We have the points as (6,2) and (15,5)

The equation of the slope is:

m = (y2-y1)/(x2-x1)

(x1,y1) = (6,2)

(x2,y2) = (15,5)

m = (5-2)/(15-6) = 3/9 = 1/3

So the equation will be;

y = 1/3x

Answer:

7m-7m=8n+8n

m=16n

Step-by-step explanation: U must first link the like terms so in order to do so u must bring over the 7m, now before u brought over the 7m it was a positive 7m now that your bring it over it turns negeitive and the same goes for the term 8n when u carry that term over it turns positive now dont let the subtraction sign foul u it still negative as long as its beside the term it is going to be negative guys dont  forget that, now on to the next step after u cross over and change signs u start to work out now that the like terms are equal u dont  need to worry about them because its given u the go ahead to workout so your main focus is on the subtracting the 7's which  is 0 and leaves u with m u dont  have to put them but i dont recommend it the u start on the next side u and the 8's which is 16 and u put bk the n u have to put bk the terms its important and thats  how u get m=16n.

Answer:

  {58, 59, 60} kg

Step-by-step explanation:

Let x represent the mass of the heavier cow. Then the mass of the lighter cow is 96 -x.

The inequalities regarding the relative masses are ...

  x ≥ 96-x +20 . . . . . the heavy cow is at least 20 kg heavier

  96 -x > 35 . . . . . . . the lighter cow is more than 35 kg

__

Adding x to the first inequality makes it ...

  2x ≥ 116

  x ≥ 58

Adding x-35 to the second inequality makes it ...

  61 > x

So the mass of the heavier cow must be in the range ...

  58 ≤ x < 61

Possible whole-number masses for the heavier cow are ...

  58 kg, 59 kg, 60 kg
