Answer:

B) 10 cm

Step-by-step explanation:

Hello!

We can use the Pythagorean theorem to solve for the hypotenuse.

Formula: a^2 + b^2 = c^2

  • a = leg
  • b = leg
  • c = hypotenuse

We can plug in the values for each leg to solve for the hypotenuse.

<h3>Solve for c</h3>
  • a^2 + b^2 = c^2
  • 6^2 + 8^2 = c^2
  • 36 + 64 = c^2
  • 100 = c^2
  • \sqrt{100} = \sqrt{c^2}
  • 10 = c

The answer is Option B: 10 cm

A 15 ounce alloy containing 30% gold was mixed with an alloy containing 5% gold to get an alloy containing 20% gold. How many ou
Studentka2010 [4]

Answer:

4.5 % alloy

Step-by-step explanation:

Let x = amt of 30% alloy

The resulting total is to be 25 oz, therefore:

(25-x) = amt of 5% alloy:

A typical mixture equation:

.30x + .05(25-x) = .20(25)

.30x + 1.25 - .05x = 5 .30x - .05x = 5 - 1.25

.25x = 3.75

x = 3.75%2F.25

x = 15 oz of 30% alloy required

then

25-15 = 10 oz of 5% alloy:

Check solution

.30(15) + .05(10) = .20(25)

4.5 + .5 = 5

A car traveled 120 miles driving 60 miles per hour. The trip took 2 hours.
Ugo [173]
To answer this all you need to do is divide 120 by 50

120/50
2.4

So it will take 2 hours and 24 minutes (.4 of 60 to get the 24)

The midpoint of chord AB is ( , ), and the slope of chord AB is
kykrilka [37]

Answer:

See solution below

Step-by-step explanation:

Let the coordinate's of A and B be (1, 0) and (2,4) respectively

midpoint M (X, Y) = [(x1+x2/2, y1+y2/2)]

X = x1+x2/2

X = 1+2/2

X = 3/2

X = 1.5

Y = y1+y2/2

Y = 0+4/2

Y = 4/2

Y = 2

Hence the required midpoint (X, Y) is (1.5, 2)

Slope m = y2-y1/x2-x1

m = 4-0/2-1

m = 4/1

m = 4

Hence the slope is 4

<em>Note that the coordinates are assumed but the same calculation can be employed for any other coordinates</em>
