Answer:

5

Step-by-step explanation:

We need to find an expression for the calculation, divide 10 in half and subtract from 50 divided into fifths .

The statement '' divide 10 into half '' means we need to divide 10 by 2, such that we get \frac{10}{2}=5 (i)

The statement '' 50 divided into fifths '' means we need to divide 50 by 5 i.e,\frac{50}{5}=10 (ii)

According to question, on subtracting (i) from (ii), we get \frac{50}{5}-\frac{10}{2}=10-5=5

3. The sum of two numbers 49. The difference of the two numbers is 15. What is the product of the two numbers?
Alborosie

Lets set the two numbers as 'a' and 'b'

Now let us set up some equations based on the information:

  • sum of two numbers 49 -->  a + b = 49
  • difference of the two numbers is 15 --> a -b =15

Equations

 a + b = 49 -- equation 1

 a - b = 15 -- equation 2

Solve:

 (equation 1) + (equation 2)

    2a = 64

      a = 32 -- equation 3

 (equation 3)'s value of a into (equation 2)

  32 - b = 15

    b = 17

The products of 'a' and 'b' is 544

Hope that helps!

Fill in the blanks with the answer to each question based on information provided.Two toy robots are having a race. Robot A can
GalinKa [24]

Answer:

  1. 1 1/14 seconds
  2. 4 2/7 seconds

Step-by-step explanation:

We are being asked for times, so we can express the rate in terms of seconds per meter.

  (15 seconds)/(14 meters) = (15/14) seconds per meter = 1 1/14 seconds/meter

__

1) It will take Robot A 1 1/14 seconds to go 1 meter.

2) it will take Robot A 4 2/7 seconds to go 4 meters. (4 times as long)

Answer:

  ∠CAB = 28°

  ∠DAC = 64°

Step-by-step explanation:

What you do in each case is make use of the relationships you know about angles in a triangle and around parallel lines. You can also use the relationships you know about diagonals in a rectangle, and the triangles they create.

<u>Left</u>

Take advantage of the fact that ∆AEB is isosceles, so the angles at A and B in that triangle are the same. If we call that angle measure x, then we have the sum of angles in that triangle is ...

  x + x + ∠AEB = 180°

  2x = 180° -124° = 56°

  x = 28°

The measure of angle CAB is 28°.

__

<u>Right</u>

Sides AD and BC are parallel, so diagonal AC can be considered a transversal. The two angles we're concerned with are alternate interior angles, so are congruent.

  ∠BCA = ∠DAC = 64°

The measure of angle DAC is 64°.

(Another way to look at this is that triangles BCE and DAE are congruent isosceles triangles, so corresponding angles are congruent.)
