The measure of the angles are 56.25° and 33.75°.

<h3>How to calculate the angles?</h3>

The value in a complementary angle is equal to 90°.

Let the first angle = x

The second angle will be: 1 - (40% × x) = 1 - 0.4x = 0.6x

Therefore, they'll be added together as follows:

x + 0.6x = 90°

1.6x = 90°

Divide

x = 90/1.6

x = 56.25

The second angle will be:

= 0.6x

Since x = 56.25, this will be used in the illustration below.

= 0.6x

= 0.6 × 56.25

x = 33.75

Therefore, the second angle is 33.75.

This illustrates the concept of complimentary angles.

If the area of a circle measures 16/25 π cm2, what is the circumference of the circle in terms of π? A) 5/8 π cm B) 4/5 π cm C)
xxTIMURxx [149]
Area=pi*r^2
16/25 therefore is r^2
therefore r=4/5
circumference = 2*pi*r
8*pi/5 is the circumference, C.

Solve the system below using elimination<br> {5x+9y= -10}<br> {7x+10y= -1}
bixtya [17]

∑Hey , jillianwagler ⊃

Answer:

x = 7, y = -5

Step-by-step explanation:

<u><em>Given~:</em></u>

<em>Solve the system below using elimination</em>

<em>{5x+9y= -10}</em>

<em>{7x+10y= -1}</em>

<u><em>Solve:</em></u>

<u><em></em></u>\begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix}

Isolate x ( 5x + 9y = -10 ) : \mathrm{x=\frac{-10-9y}{5}}

Substitute: \mathrm{x=\frac{-10-9y}{5}}

\begin{bmatrix}7\cdot \frac{-10-9y}{5}+10y=-1\end{bmatrix}

\begin{bmatrix}\frac{-70-13y}{5}=-1\end{bmatrix}

Isolate y : \frac{-70-13y}{5}=1:y=-5

Substitute: y=-5

x=\frac{-10-9\left(-5\right)}{5}=7

Hence, x=7

Therefore, the solution for \begin{bmatrix}5x+9y=-10\\ 7x+10y=-1\end{bmatrix} are:

x=7,\:y=-5

Can anyone help me with this question please thank you!
Vedmedyk [2.9K]

Answer:

B. The individual events are dependent. The probability of the combined event is 3.772%.

Step-by-step explanation:

The individual events are dependent because you would have to draw 2 red candies in a row. After the first drawing, there would be one less red candy in the bag, which would affect the second drawing.

First drawing probability: 11/54, or 20.370%

Second drawing probability: 10/54, or 18.519%

Combined probability: 20.370*18.519 = 3.772%
