Answer:

Step-by-step explanation:

Number of nickels = $1 * 1 nickel/$0.05 = 20 nickels

Thickness of 20 nickels = 20 nickels * 1.95 mm = 39 mm

Let's do the same for the quarters. Each quarter is worth $0.25.

Number of quarters = $1 * 1 quarter/$0.25 = 4 quarters

Thickness of 4 quarters = 4 quarters * 1.75 mm = 7 mm

Find the ratio of the two:

39 mm/7 mm = 5.57

Otrada [13]

What is 3.1 divided by 10.261Very simple. We have 2 given decimal number in which our dividend which is the 3.1 is lesser than our divisor which is 10.261.Now, let's start the division to be able to find out what is the quotient we're looking.=> 3. 1 / 10.261 = 0.30.Thus, the quotient is o.30, let's check if we got the correct answer.To check simply do the reverse method=> .30 * 10.261 = 3.1<span>

Given the parent function

yanalaym [24]

Answer:

Option a is right.

Step-by-step explanation:

Parent funciton is

$f(x) = x^3$

The new graph is

$f(x) = -2x^3$

Since there is no change for x, there is no horizontal shift.

BUt since sign is changed there is a reflection on the line y=0 i.e. x axis.

Also new y is -2x^3 , -2 indicates the vertical shrink by scale factor 1/2

Option a is right

i.e. there is a reflection on x axis also there is a compression of scale factor 2 vertically.

Answer:

The correct option is C ) 109.5°

Therefore,

$m\angle E=109.5\°$

Step-by-step explanation:

Given:

In Triangle DEF

d = 10

e = 18

f = 12

To Find

angle E = ?

Solution:

In Triangle DEF , Cosine Rule says

$\cos E=\dfrac{f^{2}+d^{2}-e^{2}}{2fd}$

Substituting the values we get

$\cos E=\dfrac{12^{2}+10^{2}-18^{2}}{2\times 12\times 10}$

$\cos E=\dfrac{-80}{240}=-\dfrac{1}{3}$

Therefore,

$\angle E=\cos^{-1}(-0.3333)$

$m\angle E=109.5\°$ ............As it is in Second Quadrant

Therefore,

$m\angle E=109.5\°$

lukranit [14]

Answer:

4

Step-by-step explanation:

The y-coordinate of the point where both lines intersect will give us the same solution for x.

At y = 4, both equations will have a corresponding x-value of 1.

Therefore, the value of y that that will make both equations have the same solution of x is 4.
