Which expression is equivalent to (a^3+b^4+c^5)^2

nordsb [41]

Given:

In circle O, m∠R = 30.8°.

To find:

The m∠NOQ

Solution:

Central angle theorem: According to this theorem, the central angle is always twice of subtended angle on the same arc.

Angle NOQ and angle NRQ are on the same arc but ∠NOQ is the central angle and ∠NRQ is the subtended angle on the arc NQ.

Using central angle theorem, we get

$m\angle NOQ=2\times m\angle NRQ$

$m\angle NOQ=2\times m\angle R$

$m\angle NOQ=2\times 30.8^\circ$

$m\angle NOQ=61.6^\circ$

Therefore, $m\angle NOQ=61.6^\circ$ .

How to solve 11×11-6×17+4

almond37 [142]

use the order of operations for this equation.

multiplication comes first.

11(11) - 6(17) + 4

121 - 102 + 4

for addition and subtraction, order doesn’t matter.

121 - 102 = 19

19 + 4 = 23

answer = 23

Given that y is directly proportional to x^2 and that y=2 when x=3 find the value of y when x=6

Sergio039 [100]

Answer:y=4/3

y is directly proportional to x^2 is written as

$y \alpha {x}^{2}$ introducing a constant,

y=kx^2

but from the question, when y=2 , x=3 . putting it in the formula to get the value of k

$2 = {3}^{2} \times k$

2=9k . dividing through by 9 to get the value of k

 $\frac{2}{9} = \frac{9k}{9}$ 

 $k = \frac{2}{9}$ 

putting it in the general expression

 $y = \frac{2}{9} x$ 

the value of y when x=6

 $y = \frac{2}{9} \times 6$ 

 $y = \frac{4}{3}$ 

therefore the value of y when x=6 is

4/3

Jim buys two boxes of apples. 90% of the total apples are ripe.

Sedaia [141]

Jim buys 2*15=30 apples
To get the answer we have to find 90% of 30
90% = 0.9
0.9*15=27
Now we can subtract 30-27=3 - its the answer
