Isha is 5 years younger than her brother. After 4 years, their ages will be in the ratio 2:3, find their present ages.

Answer:

20.

Step-by-step explanation:

5/8 x 32/1 = ?

This is the equation above.  First we multiply 5 by 32 and we get 160.  Now multiply 8 by 1 and we get 8.  So now the equation is "160/8 = ?"  So lets divide 160 by 8 which is 20. Therefore 20 is our answer.

Answer:

  x = 11.75

Step-by-step explanation:

The sum of the two acute angles in this right triangle is 90°.

  5x +(3x -4) = 90

  8x = 94

  x = 94/8 = 47/4

  x = 11.75

_____

The angles are ∠A=58.5° and ∠B=31.5°.

Answer:

7% and 5%

Step-by-step explanation:

The computation of the two rates of interest is shown below;

The interest  rate for $3,000 be x%

And, for $4,500 the interest rate is (x -2%)

The total interest earned is

= x% of $4,500 + (x - 2)% of $4,500

So, the two rates of interest is

x% of $4,500 + (x - 2)% of $4,500 = $435

30x + 45(x - 2) = $435

30x + 45x - 90 = $43

75x = $25

x = 7%

x - 2 = 7 - 2

= 5%

The area of the trapezoid is 40 square units.

What is the height of the trapezoid?

Answer:

Below.

Step-by-step explanation:

tan(180-ø).tan(90+ø)+xcos(90+ø).(cos90-ø) = sinø(sin180-ø)

xcos(90+ø).(cos90-ø) =  sinø(sin180-ø) -  tan(180-ø).tan(90+ø)

x =  (sinø(sin180-ø) -  tan(180-ø).tan(90+ø)) / cos(90+ø).(cos90-ø)

x = - (sin^2ø + tanø(tan(90+ø)) / cos^2ø

Answer:

Answer:

40%

Step-by-step explanation:

Step 1: We make the assumption that 675 is 100% since it is our output value.

Step 2: We next represent the value we seek with x.

Step 3: From step 1, it follows that 100\%=675.

Step 4: In the same vein, x\%=270.

Step 5: This gives us a pair of simple equations:

100\%=675(1).

x\%=270(2).

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

100%/x%  =  675/270

Step 7: Taking the inverse (or reciprocal) of both sides yields

x%/100% = 270/675

x=40%

Therefore, 270 is 40% of 675

Answer:

The discount percentage is 11.1%

Step-by-step explanation:

Here, we want to find the percentage of discount

We simply place the discount amount over the sales price multiplied by 100

we have this as;

50/450 * 100%

= 1/9 * 100%

= 100%/9

= 11.1%

The increasing order from youngest to oldest is Kim, Rachel, David, Peter

Increasing order is a method of arranging numbers from the smallest value to the largest value. The order goes from left to right.

Given that, David is twice as old as Rachel. Peter is 5 years older than David and Kim is 3 years younger than Rachel.

Since, David is older than Rachel, and the next sentence says Peter is older than David. It says Kim is younger than Rachel, so we can say Peter is oldest than comes David and then Rachel and the youngest member is Kim.

Hence, the increasing order from youngest to oldest is Kim, Rachel, David, Peter

Answer:

$55

Step-by-step explanation:

Given data

Principal = $50

Rate= 10%

Time = 1 year

The simple interest formula is given as

A= P(1+rt)

substitute

A= 50(1+0.1*1)

A= 50(1.1)

A= $55

Hence the balance in her account will be $55

Answer: 3

Step-by-step explanation:

Take your equation x-1=2

Now put 3 in for x

3-1=2

2=2

x=3

Answer:

x = 3

Step-by-step explanation:

Substitute x for each answer until you get an answer equal to 2.

3 - 1 = 2

2 - 1 = 2

1 - 1 = 2

The only correct equation is 3 - 1 = 2, so 3 is x.
