85/100=34/x

20cm×15 cm =300

32

/100 = 0.32

9514 1404 393

Answer:

  1.5 cm

Step-by-step explanation:

All areas are in cm^2. For a width w, the border will have an area equal to the product of its centerline length and its width:

  border area = 2((20-w) +(15-w))·w = w(70 -4w)

This area is 32% of the total cover area, so is ...

  0.32(20)(15) = 96

Equating these expressions for the area gives ...

  96 = 70w -4w^2

  w^2 -17.5w = -24 . . . . . divide by -4

  w^2 -17.5w +8.75^2 = -24 +8.75^2 . . . . . complete the square

  (w -8.75)^2 = 52.5625 . . . . simplify

  w -8.75 = ±√52.5625 = ±7.25

A border width only makes sense if it is between 0 and 7.5 cm, so the appropriate value for w is ...

  w = 8.75 ± 7.25 . . . . . . . . . add 8.75

  w = 8.75 -7.25 = 1.50 . . . . . the solution w=16 makes no sense

The border width is 1.5 cm.

Answer:

y=2x+1

Step-by-step explanation:

Input X=2 into the function, so y=2(2)+1, which is 5. This matches the table.

Answer:

It's the first one: y= 2x +1

Step-by-step explanation:

If you multiply 2 by 2, you'll get 4. then you add 1. You'll get 5.

same with the others-

Answer:

The maximum a person can weigh to go on the ride safely is 100.5 kg

Step-by-step explanation:

The specification for the maximum weight of each person that goes on the ride = 100 kg

Therefore, given that the maximum possible error of a measurement is equal to 1/2 multiplied by the unit of measurement, we have that the specified maximum weight, [tex]W_{max}[/tex], can be written as follows;

[tex]W_{max}[/tex] = (100 ± 0.5) kg, which gives the maximum a person can weigh to go on the ride safely as 100 kg + 0.5 kg = 100.5 kg

Answer:

D) 3cm/s

Step-by-step explanation:

Speed (or velocity) is calculated with d/t (distance/time). From the multiple-choice options, we know the unit is cm/s, which makes it super convenient.

Now, using the equation and seeing that 27cm is the distance and 9s is the time, 27/9 =3.

Therefore, the answer is D, 3cm/s.

Answer:

300, 120, 80 and 32 respectively.

Step-by-step explanation:

To break it down for easy multiplication, write

38 as 30 + 8

14 as 10 + 4

Now let's multiply

(30 + 8)(10 + 4) = 300 + 120 + 80 + 32

So the areas of each part would be

300, 120, 80 and 32 respectively.

Step-by-step explanation:

If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

Answer:

57,585

Step-by-step explanation:

55,000.x4.7%=2585.

55000.+2585=57,585

Answer:

$57,337.50

Step-by-step explanation:

In order to get the answer we would have to add 55, 000 and 4 [tex]\frac{1}{4}[/tex]% of 55,000 (because of the interest rate). In order to find 4 [tex]\frac{1}{4}[/tex] % we would have to multiply 55, 000 by 0,0425. So now we get the following.

Total cost of the loan = 55,000 + 55,000 x 0.0425 = 55,000 + 2,337.5 =

57,337.5

Answer:

Use the SOH CAH TOA

Step-by-step explanation:

Angle = 60°

x = opposite o

y = adjacent a

10√ 3 = hypotenuse h

To find x we use SOH {sineø = o/h}

Sin 60° = x/10√ 3

x=10√ 3 * sin 60

X=15

You can use Pythagoras theorem or CAH{cosø = a/h}

Cos 60°= y/10√ 3

y=Cos 60° * 10√ 3

y=5√ 3

Answer:

43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)

38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)

19 is what goes in the box

Answer: The answer would be the favorable out some (how many blues) over the total outcomes (all marbles added together)

So the answer would be 3/14 or 21%
