The manager of a store that specializes in selling tea decides to experiment with a new blend. She will mix some Earl Grey tea t

amid [387]

The new tea is 75% Earl Grey and 25% Orange Pekoe.
$4 / pound times 75% = $3
$2 / pound times 25% = $0.5
$3 + $0.5 = $3.50 / pound

600 pounds times 75% = 450 pounds of Earl Grey
600 pounds times 25% = 150 pounds of Orange Pekoe

NASA launches a rocket at t = 0 seconds. Its height, in meters above sea level, as a function of time is

balu736 [363]

If h is m above the ocean and your trying to find when the rocket reaches that ocean… as the function gives the height above the ocean at a given time, when the height equals 0 the rocket will have reached the ocean so solve for t when h=0. working out in the photo. i got t=48.88seconds

I need help please.

makkiz [27]

Answer:

see explanation

Step-by-step explanation:

Using the rules of radicals/ exponents

$a^{m}$ × $a^{n}$ = $a^{(m+n)}$

$a^{\frac{m}{n} }$ ⇔ $\sqrt[n]{a^{m} }$

Simplifying each term

7 $\sqrt{x^{3} }$ = 7 $x^{\frac{3}{2} }$

x $\sqrt{9x}$

= x × $\sqrt{9}$ × $\sqrt{x}$

= x × 3 × $x^{\frac{1}{2} }$

= 3 × $x^{(1+\frac{1}{2}) }$

= 3 $x^{\frac{3}{2} }$

Subtracting the 2 simplified like terms, that is

7 $x^{\frac{3}{2} }$ - 3 $x^{\frac{3}{2} }$

= 4 $x^{\frac{3}{2} }$ ← return to radical form

= 4 $\sqrt{x^{3} }$

PLEASE HELP ME!! 1.02: Triangle Similarity 1<br><br> What is the value of X?

hichkok12 [17]

Answer:

<h2>x = 28</h2>

Step-by-step explanation:

ΔARP and ΔCRD are similar. Therefore the sides are in proportion:

$\dfrac{AR}{CR}=\dfrac{PR}{DR}$

We have:

AR = 10 + x

CR = x

PR = 15 + 42 = 57

DR = 42

Substitute:

$\dfrac{10+x}{x}=\dfrac{57}{42}$ <em>cross multiply</em>

$42(10+x)=57x$ <em>use distributive property</em>

$(42)(10)+(42)(x)=57x$

$420+42x=57x$ <em>subtract 42x from both sides</em>

$420=15x$ <em>divide both sides by 15</em>

$x=28$
