what is the slope of a 5-foot high platform that begins at ground level 10 feet from the base of the platform?

Sladkaya [172]

Answer:

11.2 feet

Step-by-step explanation:

Given: Height of platform (Opposite)= 5 foot

Distance of slope from the base of platform (adjacent)= 10 feet

Picture drawn to show the measurement.

Lets find the length of slope.

Using the Pythagorean theoram.

$hypotenous^{2} = opposite^{2} + adjacent^{2}$

Subtituting the value in the formula.

$hypotenous^{2} = 5^{2} + 10^{2}$

⇒ $hypotenous^{2} = 25 + 100$

⇒ $hypotenous^{2} = 125$

Putting square root on both side

We know, √a²= a

⇒ $hypotenous = \sqrt{125}$

∴ hypotenous= 11.18 $\approx 11.2 \ feet$

Hence, the slope is 11.2 feet

In Lucy's coin collection, 15% of the coins are quarters.

stepan [7]

The total number of coins in Lucy's coin collection is equal to 80 coins.

Let the total number of coins be C.

<u>Given the following data:</u>

Percentage of quarters = 15%

Total number of quarters = 12 quarters

To the total number of coins in Lucy's coin collection:

Since the percentage of the quarters in Lucy's coin collection is equal to fifteen percent (15%) of the total number of coins. Thus, we would multiply the total number of coins by 15% and equate it to 12 quarters.

<u>Total number</u><u> of </u><u>coins</u><u>:</u>

$\frac{15}{100} \times C = 12\\\\15C=12 \times 100\\\\15C =1200\\\\C=\frac{1200}{15}$

C = 80 coins.

PLSS HELP Lacy draws a design for an art contest on a 4 in. x 5 in. card. The second phase of the contest requires the drawing t

Alex

Answer:

the 4" side of the card was scaled up to 10.5

then the scaling factor is 10.5/4 = 2.625.

The 5 side would be the length 5 x 2.625 = 13.125 which exceeds the maximum dimension of 11.

Thus, it is the 5 side which is scaled up to 10.5 and the scaling factor is therefore 10.5/5 = 2.1.

The scaled up length of the 4 side is thus 4 x 2.1 = 8.4.
