There is a bag with only milk and dark chocolates.

Novay_Z [31]

Answer:

12 milk chocolates.

Step-by-step explanation:

-We know that probabilities add upto 1:

$P(milk)+P(dark)=1\\\\P(milk)+\frac{7}{9}=1\\\\P(milk)=\frac{2}{9}$

Let X be the total number of chocolates. We know that probability is the successful events divided by the total number of events:

$P(dark)=\frac{dark \ events}{total \ events}\\\\\\\frac{7}{9}=\frac{42}{X}\\\\X=54$

#We subtract the number of dark chocolates from X to get the number of milk chocolates:

$N_m=X-N_d\\\\=54-42\\\\=12$

Hence, there must be 12 milk chocolates.

Where is the hole for the following function located?

Katena32 [7]

Answer:

x =-3

Step-by-step explanation:

A hole of a simplified rarional funcrion as the one given above exists when there is a number that can make both the numerator & the denominator = 0

so plug -3 in the x of the function & you'll get 0/0 which is indeterminate & thus implies the existence of a hole

A rectangle has a perimeter of 116 centimeters and a length of 26 centimeters what is the width of the rectangle

notsponge [240]

Answer:

The width of the rectangle=32 cm

Step-by-step explanation:

We are given that

Perimeter of rectangle, P=116 cm

Length of rectangle, l=26 cm

We have to find the width of the rectangle.

We know that

Perimeter of rectangle, P= $2(l+b)$

Where l=Length of rectangle

b=Width of rectangle

By using the formula

$116=2(26+b)$

$\frac{116}{2}=26+b$

$58=26+b$

$58-26=b$

$32=b$

Hence, the width of the rectangle=32 cm

Given quadrilateral RSTU, determine if each pair of sides (if any) are parallel and which are perpendicular for the coordinates

Mrac [35]

Slope RS: 2/3
Slope ST: -3/2
Slope TU: 4/6 = 2/3
Slope UR: -1/5

Sides RS and TU have the same slope, so they are parallel.
The slope of side ST is the negative reciprocal of the slopes of sides RS and TU, so side ST is perpendicular to sides RS and TU.
Side UR is not parallel or perpendicular to any other side.

The quadrilateral is a trapezoid.
