How can u tell that 647 is less than 674?

2 answers:

7 0

I can tell because in 647, 4 is in the tens place. In 674, 7 is in the tens place. That tells me right away that 674 is bigger. Look at the hundreds place first, then move to the tens. 7 is bigger than 4.

When gold medalist Ren Qian prepared for her dive from the 10 meter platform during the

Romashka-Z-Leto [24]

Answer:

Ren was 27.5 meters away from her family.

Step-by-step explanation:

Ren Qian was at a height of 10 meters to the ground. Let the distance from her vertical point on the ground to her family (i.e the ground distance) be represented by x.

But the angle of depression is measured with respect to the horizontal plane, so;

the vertical angle = $90^{o}$ - 20°

= $70^{o}$

Applying the appropriate trigonometric function, we have;

Tan θ = $\frac{opposite}{adjacent}$

Tan $70^{o}$ = $\frac{x}{10}$

⇒ x = 10 x Tan $70^{o}$

= 10 x 2.7475

= 27.475

x = 27.5 meters

Ren was 27.5 meters away from her family.

melanie made a circular necklace she puts beads evenly spaced around the necklace if the 4th bead is directly across from the 11

dangina [55]

Answer:

Step-by-step explanation:

If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total bead
