Mathematics
1 answer:
lutik1710 [3]2 years ago

Answer:

Step-by-step explanation:

1. Eggs are sold at a price of P 105.00 per dozen.

Rate = \frac{1}{105}

2. The carpentry job can be done by 3 carpenters in 4 days.

Rate at which each carpenter works = \frac{4}{3} = 1\frac{1}{3} days

This shows that each carpenter worked for an average of 1.3333 days to complete the job.

3. Five tickets are sold at P 600.00

The price for one ticket = \frac{600}{5}

                                       = 120

One ticket is sold for P 120.00.

4. The dollar's rate is P 52.00.

This implies that;

1 dollar = P 52.00

dollar rate = \frac{1}{52}

5. The ratio of water to milk in the recipe is 1 to 4.

This implies that to 1 measure of water, 4 measures of milk is used in the recipe.

rate = \frac{1}{4}

Factorize completely the expression(h+2k)²+4k²-h²​
julsineya [31]

The expression factorized completely is (h +2k)[(h+2k) + (2k-h)]

From the question,

We are to factorize the expression (h+2k)²+4k²-h²​ completely

The expression can be factorized as shown below

(h+2k)²+4k²-h²​ becomes

(h+2k)² + 2²k²-h²​

(h+2k)² + (2k)²-h²​

Using difference of two squares

The expression (2k)²-h²​ = (2k+h)(2k-h)

Then,

(h+2k)² + (2k)²-h²​ becomes

(h+2k)² + (2k +h)(2k-h)

This can be written as

(h+2k)² + (h +2k)(2k-h)

Now,

Factorizing, we get

(h +2k)[(h+2k) + (2k-h)]

Hence, the expression factorized completely is (h +2k)[(h+2k) + (2k-h)]

Lines l and m are parallel
soldi70 [24.7K]

Answer:

  • m∠ABC = 15°

Step-by-step explanation:

<u>Given</u>

  • m∠ABC = x°
  • m∠BCD = 25°
  • m∠CDE = 55°
  • m∠DEF = 3x°

Add two more parallel lines passing through points C and D.

Consider alternate interior angles formed by the four parallel lines.

<u>The angles between the two middle lines are equal to:</u>

  • m∠BCD - m∠ABC  = m∠CDE - m∠DEF

<u>Substitute values and solve for x:</u>

  • 25 - x = 55 - 3x
  • 3x - x = 55 - 25
  • 2x = 30
  • x = 15

m∠ABC = 15°
