Answer:

x = 48

Step-by-step explanation:

RULE:

a^2 + b^2 = c^2

1. x^2 + 36^2 = 60^2

2. x^2 + 1296 = 3600

3. subtract 1296 on both side of the equation.

4. x^2 = 2304

5. square root it.

6. \sqrt[]{x^2} =  \sqrt[]{2304}

7. x = 48

zmey [24]

Answer:

Step-by-step explanation:

a + c = 92.....c = 92 - a

8a + 5c = 688

8a + 5(92 - a) = 688

8a + 460 - 5a = 688

3a = 688 - 460

3a = 228

a= 228/3

a = 76 <==== adults

a + c = 92

76 + c = 92

c = 92 - 76

c = 16 <=== children

Nataly_w [17]

Answer D). 9 ft is correct

Height of the ball at a horizontal distance of 10 feet is 9 ft

Step-by-step explanation:

A ball is thrown and it follows a parabolic path. At each horizontal distance (x) the following equation models the ball’s height (y).

Y(x) = -0.02x^{2} +0.8x+3

Question asked is " What will be height (Y) of the ball when X=10 ft "

Simply putting value of X in given equation

we get,

Y(x) = -0.02x^{2} +0.8x+3

Y(x) = -0.02(10)^{2} +0.8(10)+3

Y(x) = -0.02(100)} +8+3

Y(x) = -2 +8+3

Y(x) = 9

<em>Therefore,</em> Height of the ball at a horizontal distance of 10 feet is 9 ft

Answer D.  9 ft is correct

If Q is the midpoint of segment PR, PQ = 17 cm, then what is the total length of PR?
Tpy6a [65]

Answer:

34 cm

Step-by-step explanation:

PR = PQ + QR

PQ = QR because Q is the mid-point

Since PQ = 17 cm, then QR = 17 cm

so,

PR = 17 + 17

PR = 34 cm
