Answer:

The Pythagorean Theorem states that a^2+b^2=c^2

Step-by-step explanation:

This formula applies to the side lengths and means that the length of leg "a" squared, plus the length of leg "b" squared, will equal the length of hypotenuse "c" squared. Please state a more specific question so I can go into more detail if you need it :)

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

A basket of laundry is being separated. Divide 48 pieces into 2 clothing groups so the ratio is 1 to 3
KiRa [710]
\bf 48\qquad 1:3\qquad \cfrac{1}{3}\qquad \qquad \cfrac{1\cdot \frac{48}{1+3}}{3\cdot \frac{48}{1+3}}\implies \cfrac{1\cdot 12}{3\cdot 12}\implies \cfrac{12}{36}

btw, don't put the shirts in the same bundle as the socks, you may end up with an unwanted perfume.

If f ( x ) = 7 ( x − 1 ) + 8 f(x)=7(x−1)+8 , what is the value of f ( 1 ) f(1) ?
antiseptic1488 [7]

Answer:

8

Step-by-step explanation:

f(1) is another notation for x = 1

so we’ll plug in 1 for x

f(1) = 7((1) -1) +8

f(1) = 7(0) +8

f(1) = 0 +8

f(1) = 8

QUICKLY<br> A sphere has a radius of 4 in. Which equation finds the volume of the sphere?
MissTica

Volume of sphere formula: V = 4/3πr³

We are given the radius of 4, so, input that with r in the formula.

V = 4/3π(4)³

As we can see, option B has what we wrote above. So, that is the correct answer.

The answer is Option B.

Best of Luck!
