Which of the following statements must be true about this diagram? Check all that apply.
pishuonlain [190]

Answer:

Options (D), (E) and (F) are the correct options.

Step-by-step explanation:

From the figure attached,

1). Angle 4 is the exterior angle of the given triangle having interior angles 1, 2 and 3.

Therefore, by the property of exterior angle,

∠4 = ∠1 + ∠2

2). Since ∠4 = ∠1 + ∠2,

Therefore, ∠4 will be greater than ∠1

 Similarly, ∠4 will be greater than ∠2

Therefore, Options (D), (E) and (F) are the correct options.

Nadiya determines that there are no fractions equivalent to 2/10 with a denominator greater than 10, but less than 20, that have
frosja888 [35]

Answer:

Yes, Nadiya is correct. By multiplying the numerator and denominator by 2, the first fraction equivalent to 2/10 is 4/20.

Step-by-step explanation:

To find a fraction equivalent to 2/10, we need to multiply (or divide) the numerator and denominator by the same nonzero whole number.

As we need an equivalent fraction with a denominator greater than 10, we will need to multiply and not divide.

The first nonzero whole number we have is 1. If we multiply the numerator and denominator by 1, we get 2/10. Obviously, 2/10 is equivalent to 2/10 but the denominator is not greater than 10, so it doesn't help us.

The next whole number is 2. When we multiply the numerator and denominator by 2, we get 4/20. The denominator is not less than 20.

If we keep going, we will get 6/30, 8/40 and so on.  

Therefore, Nadiya is correct.

The correct answer is the first one.

Brad measured the length of an object as 2.1 * 10^4 cm. Which items might he have measured? Check all that apply.
Airida [17]

Answer with explanation:

Length of an object

                           =2.1\times 10^4\\\\=2.1 \times 10000\\\\=21,000cm

Other unit of measurement are Meter and Kilometer.

→1 Meter = 100 cm

→1 Kilometer= 1,000 meter=100,000 cm

→→21,000 cm = 210 meter = 0.21 Km

Option B:→ length of a city park, is most suitable measurement ,among all other measurement ,that Brad has done.

Second option Might be: Option A→ Length of a city block , may be That Brad has measured.

All other options are Inappropriate, as they require smaller scale or may be larger Scale ,that brad has used to measure

1.≡ Height of a person →→→240 cm (Maximum of 8 feet)

2.  ≡Distance across a city  →→→1 Km or 2 Km or 3 Km...

3.  ≡Height of an apple tree→→→1,000 cm (Maximum)  

4. ≡Width of a screen in a theater→→→2,100 cm (Maximum)

5 ≡depth of water in a swimming pool→→→225 cm

None of the five things described above appears, that brad has measured.
