How many triangles can be constructed with angles measuring 50,90,40

inn [45]

Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*

Hope this helped you!

Oliver picks a 4-digit even number that is greater than 3000.

Irina18 [472]

Answer:

Hello,

why not 700 ?

Step-by-step explanation:

$n=\overline{abcd}\\a\in \{3,4,5,6,7,8,9\}: 7\ possibilities\\b\in\{4,8\} :2\ possibilities\ :0 \ in\ USA\ is\ not\ a\ multiple\ of\ 4\\c \in\{0,1,2,3,4,5,6,7,8,9}: 10\ possibilities\\d \in \{0,2,4,6,8\}:5\ possibilities\\$

7*2*10*5=700

Impossible to reach 3000 since 2nd digit is 4 or 8.

Evaluate each expression for s=4 and t=8 1) (25)^2t 2) 2st^2-5^2 3) 2s^2-t^3/16

stepladder [879]

Answer:

1. 2.328× $10^{22}$

2. 487

3. 30.52 OR 0 (see explanation↓)

Step-by-step explanation:

1. $(25)^{2t}$

(sub for t=8)

= $25^{2*8}$

= $25^{16}$

=2.328× $10^{22}$

2. $2st^{2} -5^{2}$

(sub for s=4 and t=8)

=2×4× $8^{2}$ - $5^{2}$

=512-25

=487

3. $2s^{2} -t^{3/16}$ (the equation is not clear so I will do $2s^{2} -\frac{t^{3} }{16}$ as well)

FOR $2s^{2} -t^{3/16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $8^{3/16}$

=32-1.476826146

=30.52 (to the nearest 2 decimal place)

FOR $2s^{2} -\frac{t^{3} }{16}$

(sub s=4 and t=8)

=2× $4^{2}$ - $\frac{8^{3} }{16}$

=32-32

Nya wants to buy a yellow sweater that had an original price of $55. The sweater is now discounted 30% and the sales tax rate is

Readme [11.4K]

Answer: Nya will pay $40.81 for the sweater.

Step-by-step explanation: First, take $55, and multiply it by 0.3 to get 30 percent of $55. This turns out to be $16.5. Next, you do $55 - $16.5 because the sweater is 30% off, and not 30% of the original rate. Now you multiply the difference of $55 - $16.5, so $38.5, and you multiply it by 0.06 to get $2.31. Last, add $38.5 and $2.31 to get $40.81.
