Meghan has two less dimes as she does nickels and one more than double the amount of quarters as she does nickels for a total of

defon

Answer:

The number of nickel = 3

Number of dime = 1

Number of quarter = 7

Step-by-step explanation:

Let us assume the number of nickels Meghan has = m

So, the number of dimes she has = m -2

And the number of quarters she has = 1 + 2 m

Now, the total amount she has = $2.00

1 nickel = $0.05 ⇒ m nickel = m ($0.05) = 0.05 m

1 dime = $0.10 ⇒ (m -2) dime = m-2 ($0.10) = 0.10 (m-2)

1 quarter = $0.25 ⇒ (1+ 2m) quarter = (1+ 2m) ($0.25) = 0.25 (1+2m)

So, according to the question:

Amount of (nickel + dime + quarter) = $2.00

⇒ 0.05 m + 0.10 (m-2) + 0.25 (1+2m) = 2

or, 0.05 m + 0.10 m - 0.20 + 0.25 + 0.5 m = 2

or, 0.65 m = 2 - 0.05

or, m = 1.95/0.65 = 3

or, m = 3

Hence, the number of nickel = 3

Number of dime = m -2 = 3-2 = 1

and Number of quarter = 2m + 1 = 7

Kalei is 6ft tall and stands 10 feet from a tree. He measures an angle if elevation of 30° up to the coconuts on the tree. How h

Juli2301 [7.4K]

Answer:

The total height of coconut Tree = H + 10ft = 11.77 ft

Step-by-step explanation:

Given as,

The height of Kalei = 6ft

The distance of Kalei from the coconut Tree = 10 feet

Angle of elevation of kalei up to the coconut on tree = 30°

<u>Note : look at the pic attache </u>

From figure it is mention that

Total height of Tree = 6 ft + H

So, Tan 30° = $\frac{perpendicular}{base}$

Tan 30° = $\frac{H}{10}$

∴ H = 10 Tan 30° = 10 × 0.577 Note : tan 30° = 0.577

i.e H = 5.77 ft

Hence the total height of coconut tree = 6 + 5.77 = 11.77 ft Answer
