Answer:

Answer for Question A) Yared will still need to wrap 4 more presents when Luke is finished.

Explanation for Question A) Yared will still need to wrap 4 more presents because he has a slower rate of wrapping his presents. Yared wraps 3 presents every 15 minutes (or you can write it as 4 presents every 20 minutes) and Luke wraps 5 presents for every 20 minutes. So Luke is faster at wrapping than Yared. Therefore Yared will have 4 more presents to finish when Luke is done.

Answer for Question B) Yared will still need to wrap 20% of his presents when Luke finishes.

Explanation for Question B) It is the same as the other one except you just have to make it a percentage. So 16/20 as a percentage is 20%.

Sorry if I can't explain very well, but those are the correct answers!

Hope this helps you!!

icang [17]

Answer:

-10 feet below the surface of the water

Step-by-step explanation:

We are told that the dive rings position at the bottom of the pool is 10 feet below the surface of the water.

Now, an integer is basically a whole number that can either be be zero, positive or negative.

In this case, it's below the surface which means it's below zero.

Thus, it's negative.

So the integer is -10 feet below the water surface.

What is the value of a? 5 units 5 and one-third units 6 and two-thirds units 7 units
blagie [28]

The missing figure is attached

The value of a is 5\frac{1}{3} ⇒ 2nd answer

Step-by-step explanation:

Let as revise the Pythagoras Theorem

In the right triangle ABC, where ∠B is a right angle (AC is the hypotenuse, Ab and BC are the legs of the right angle)

  • (AC)² = (AB)² + (BC)²
  • (AB)² = (AC)² - (BC)²
  • (BC)² = (AC)² - (AB)²

If BD is drawn perpendicular to AC, we can use these rules

  • (AB)² = AD × AC
  • (BC)² = CD × AC
  • (BD)² = AD × CD
  • AB × BC = BD × AC

In Δ WYZ

∵ m∠WYZ = 90°

- By using Pythagoras Theorem

∴ (WZ)² = (WY)² + (YZ)²

∵ WY = 4 units

∵ YZ = 3 units

∵ WZ = c units

∴ c² = (4)² + (3)²

∴ c² = 16 + 9 = 25

- Take √ for both sides

∴ c = 5

In Δ XWZ

∵ m∠XWZ = 90°

∵ WY ⊥ XZ

- We can use the rule (WZ)² = ZY × ZX

∵ (WZ)² = ZY × ZX

∵ WZ = 5 units

∵ ZY = 3 units

∵ ZX = (3 + a) units

∴ (5)² = 3(3 + a)

∴ 25 = 9 + 3a

- Subtract 9 from both sides

∴ 16 = 3a

- Divide both sides by 3

∴ a = 5\frac{1}{3}

The value of a is 5\frac{1}{3}

6.25t plus 8 = 12.5t plus 13
givi [52]

6.25t + 8 = 12.5t + 13

Subtract 8 from both sides

6.25t = 12.5t +5

Subtract 12.5t from both sides

-6.25t = 5

Divide -6.25 by both sides

t = 0.8
