Answer 1
Answer:

Answer:

1.  50 meters by 40 meters

2.  20 meters by 10 meters

3.  60 meters by 48 meters

4. DrawingGym Area = 18 sq. cm. and  Actual Gym Area = 2592 sq. m.

Step-by-step explanation:

1.

The drawing length of the GYM+CLOSET area is:

5 cm by 4 cm

Since 1 cm represents 10 m in real life, we can say the real life dimensions are:

5cm * 10 = 50 meters

4 cm * 10 = 40 meters

THe actual measurements of gym (including closet):

50 meters by 40 meters

2.

The drawing measurement of the closet would be:

2 cm length given and 1 cm width given

Since we know 1 cm represents 10 meters in real life, the actual measurements would be:

1cm * 10 = 10 meters

2 cm * 10 = 20 meters

The actual dimensions of closet:

20 meters by 10 meters

3.

Gym + Closet area is still 5cm by 4cm in the drawing.

Now, the scale changes. The new scale is:

1cm = 12 meters

So,

5cm * 12 = 60 meters

4 cm * 12 = 48 meters

The actual measurement of Gym and Closet (new scale):

60 meters by 48 meters

4.

First, let find the area of the gym. This will be total area - closet area

We know area of rectangular figure is Length * Width

SO,

Total Area = 5 * 4 = 20

Closet Area = 2 * 1 = 2

Thus,

Gym Area = 20 - 2 = 18

Gym Area = 18 sq. cm.

In real life (1cm = 12 m -- new scale), Gym Area would be:

Gym Area = 18cm^2*(12m)/(1cm)*(12m)/(1cm)=18*12*12m^2=2592m^2

Actual Gym Area = 2592 sq. m.

The answer is A) -3/2

To answer this question you basically have to re write this equation, so you have something that equals x/y

First cross multiply: (3)/(2)= (2x)/(2x+y) is the same as 3(2x+y)=2(2x) then you simplify getting 2x=-3y divide by 2 on both sides and get x= (-3y)/(2) and finally divide by y on both sides and get (x)/(y) = (-3)/(2) , so (-3)/(2) is the answer :)

Answer:

Well I don't know how to explain it but when i worked it out the answer that came out is A -3/2

Students in Miss Moseley's fourth grade class are learning multiplication, and they demonstrate mastery by passing assessments. Travis has passed 11 tests, and his classmate, Jenifer, has passed 2 tests. Going forward, Travis plans to pass 2 tests per week. Meanwhile, Jenifer plans to pass 5 tests per week. Eventually Jenifer will catch up to Travis. When the number of tests each student has passed are equal, how many tests will each student have passed and how many weeks will it take?

Answers

Answer:
Each will have passed 17 tests and it will take 3 weeks.

Explanation:
Let x be the number of weeks.
The number of tests Travis passes to begin with is 11.
We then add 2 tests per week, or 2x to that, giving us:
11+2x.

The number of tests Jenifer has passed to begin with is 2.
We then add 5 tests per week, or 5x to that, giving us:
2+5x.

Setting these equal, we have:
11+2x=2+5x.

Subtract 2x from each side:
11+2x-2x=2+5x-2x;
11=2+3x.

Subtract 2 from each side:
11-2=2+3x-2;
9=3x.

Divide both sides by 3:
(9)/(3) = (3x)/(3);
3=x.

It will take 3 weeks.
In 3 weeks,
Travis will have passed:
11+2*3 = 11+6 = 17 tests.
Jenifer will have passed the same number, since she catches up with him at this point.

Answer:

Each will pass 17 test after 3 weeks.

Step-by-step explanation:

Consider the provided information,

Let x is the number of weeks.

Travis has passed 11 tests and plans to pass 2 tests per week.

11+2x

Jenifer, has passed 2 tests and plans to pass 5 tests per week.

2+5x

Now equate them as shown.

11+2x=2+5x

11-2=5x-2x

9=3x

x=3

Hence, after 3 weeks both have passed the same number of test.

Substitute x=3 in 11+2x

11+2(3)=17

Hence, each will pass 17 test after 3 weeks.

5/10 + 8/100= ?
13/100, 40/100, 58/100, 6/10

Answers

Answer:

58/100

Step-by-step explanation:

The first step is to make the two fractions have a common denominator. 5/10=50/100. Now you can add the two fractions together. 50/100+8/100=58/100. Hope this helps!
58 / 100 is the answer
