Answer:

z=\sqrt{80}

Step-by-step explanation:

By geometric mean property:

y= \sqrt {16\times 4}

y= \sqrt {64}

y= 8

By Pythagoras Theorem:

z=\sqrt{4^2 +8^2}

z=\sqrt{16 + 64}

z=\sqrt{80}

Use the spinner shown to answer the question. Assume that it is equally probable that the pointer will land on any one of the co
Drupady [299]

The probability that the pointer lands in a region that is red or blue is 1/2

<h3>How to determine the probability?</h3>

The spinner that completes the question is added as an attachment

From the attached spinner, we have:

  • Total section = 8
  • Red or blue = 4

The probability is then calcuated as:

P =Red or blue/Total section

This gives

P =4/8

Evaluate

P= 1/2

Hence, the probability that the pointer lands in a region that is red or blue is 1/2

How do you solve<br> y=7x-10 <br> y=-3
strojnjashka [21]

Answer:

x = 1

Step-by-step explanation:

If y = -3...

y = 7x - 10

-3 = 7x - 10

10 + -3 = 7x - 10 +10

7 = 7x

(1/7) 7 = 7x (1/7)

1 = x

Solve for x in the triangle. Round your answer to the nearest tenth.
kramer

Answer:

<h2>x = 10.3</h2>

Step-by-step explanation:

Use sine.

sine=\dfrac{opposite}{hypotenuse}

We have:

opposite=x\\hypotenuse=16

\sin40^o\approx0.6428        <em>look at the table in the picture</em>

Substitute:

\dfrac{x}{16}=0.6428         <em>multiply both sides by 16</em>

x=10.2848\to x\approx10.3
