Answer:

It would be 1.5m+4 is greater than or equal to 7. This is because 1.5m is the regular rate of growth, plus the 4cm already grown. She wants the hair to be no shorter than 7cm. So, the 15m+4 has to be greater than the 7cm.

Answer:

2/5

Step-by-step explanation:

If it landed right side up 12 times out of a total of 30 times, you can write this as a fraction: 12/30.

Simplify the fraction:

12/30 divided by 6/6

2/5

This means that 2/5 is the probability.

Solve for m and n<br> I been stuck on this question for an hour

Crazy boy [7]

Answer:

m = 10 , n = 5 $\sqrt{2}$

Step-by-step explanation:

using the cosine and tangent ratio in the right triangle and the exact values

cos45° = $\frac{1}{\sqrt{2} }$ and tan45° = 1 , then

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{5\sqrt{2} }{m}$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

m = 5 $\sqrt{2}$ × $\sqrt{2}$ = 5 × 2 = 10

-----------------------------------------

tan45° = $\frac{opposite}{adjacent}$ = $\frac{n}{5\sqrt{2} }$ = 1 , then

n = 5 $\sqrt{2}$

No.

$\sqrt{45}=3\sqrt{5} \\2\sqrt{20} =2\sqrt5}$

If you add them up you DO NOT GET $5\sqrt{5}.$ According to mathematics, it equals to $7\sqrt{5}$ .
