Question 6 of 9 (3•8) • 1 = 3 • (8.1) O A. True B. False​
olga nikolaevna [1]

Answer:

No, (false). The question I assume was: (3*8)*1=3*(8.1)

Step-by-step explanation:

1. Multiple: 3 * 8 = 24

2. Multiple: <em><u>The result of step No. 1:</u></em> * 1 = 24 * 1 = 24

3. Conversion a decimal number to a fraction: 8.1 = \frac{81}{10} = \frac{81}{10}

   a) Write down the decimal 8.1 divided by 1: 8.1 = \frac{81}{1}

   b) Multiply both top and bottom by 10 for every number after the

       decimal point. (For example, if there are two numbers after the decimal

       point, then use 100, if there are three then use 1000, etc.)

       \frac{8.1}{1} = \frac{81}{10}

   Note: \frac{81}{10} is called a decimal fraction.

   c) Simplify and reduce the fraction

       \frac{81}{10} = \frac{81*1}{10*1} = \frac{81}{10}

4. Multiple: 3 * 8.1 = \frac{3*81}{1*10} = \frac{243}{10}

   Multiply both numerators and denominators. Result fraction keep to lowest

   possible denominator GCD(243, 10) = 1. In the next intermediate step the

   fraction result cannot be further simplified by canceling.

   In words - three multiplied by eighty-one tenths = two hundred forty-three

   tenths.

5. Compare: <em><u>The result of step No. 2 </u></em>vs <em><u>The result of step No. 4</u></em>: = 24 vs \frac{243}{10} = \frac{24}{1} vs \frac{243}{10} = \frac{24*10}{1*10} vs \frac{243}{10} = \frac{240}{10} vs\frac{243}{10} = 240 vs 243 = No

In the figure below, △ A B C ∼△ D E F . BX and EY are altitudes of each triangle. Find the measure of EY to the nearest tenth.
Svetllana [295]

Answer:

EY≅ 5.33 cm (nearest to tenth)

Step-by-step explanation:

Two triangles are said to be similar to each other if they have the same shape

(not necessarily the same size) and their corresponding sides are in

proportion

Given that,

AB = 12

DE = 8

BX = 8

ΔABC ∼ ΔDEF means that

  1. ∠A ∼= ∠D, ∠B ∼=∠E and ∠C ∼= ∠F.
  2. Further more, their corresponding sides are in proportion.

So,

12/8 = 8/EY

(by doing cross multiplication)

12EY = 8 × 8

12EY = 64

EY = 64 / 12

EY= 5.3333

EY≅ 5.33 cm (nearest to tenth)
