What is the value of q?

skad [1K]

Answer:

<h2>2√14</h2>

Step-by-step explanation:

ΔSQR and ΔTSR are similar. Therefore the sides are in proportion:

$\dfrac{SR}{QR}=\dfrac{TR}{SR}$

We have:

SR = q

QR = 10 + 4 = 14

TR = 4

Substitute:

$\dfrac{q}{14}=\dfrac{4}{q}$ <em>cross multiply</em>

$(q)(q)=(14)(4)\\\\q^2=56\to q=\sqrt{56}\\\\q=\sqrt{4\cdot14}\\\\q=\sqrt4\cdot\sqrt{14}\\\\q=2\sqrt{14}$

What is the length of BC in the right triangle below 21 and 72

sleet_krkn [62]

Im guessing 21 and 72 are the side lengths for the triangle?

Alright, so since it's a right triangle you can use the Pythagorean theorem or a^2+b^2=c^2

Since i cant see the picture, im going to use some general math <span>so i</span> can figure out if those two sides are the legs or if one of them is the hypotenuse
Alright
so im guessing the side we're trying to find is the hypotenuse

21^2+72^2=c^2
441+5184=c^2
5625=c^2
<span>√5625=c</span>
75=c

The answer is 75, hope i helped!

33% of what number is 1.45

MAVERICK [17]

33% of 4.3939 is 1.45

Convert your percentage into a decimal:
$\frac{33}{100} = 0.33$

Divide both of your decimals:
$1.45 \div 0.33 = 4.3939$
