What equation relates the number of quarters x and the number of quarters x and the number of dime y to the goal of $10

1 answer:

.25 because that is the value of the quarter, times x the number or quarters you have and .10 because that is the value of the dime times y, the number of dimes you have.

A density curve of all the possible ages between 0 years and 25 years is in the shape of a triangle. What is the height of the t

Bad White [126]

Answer:

Step-by-step explanation:

Note that the area under a probability density curve must be 1.

The formula for the area of a triangle is A = (1/2)(base)(height).

Here the base is 25 units. Thus, A = 1 unit^2 = (1/2)(25 units)(height), or, after multiplying both sides of this equation by 2:

2 units^2 = ( 25 units)(height)

2 units^2

Then (height) = --------------------- = 0.08 unit

25 units

The height of the triangle is 0.08 unit.

A = 1 4 π d 2 what is the formula to calculate the diameter of a circle

Anestetic [448]

Answer:

$D=2\sqrt{\frac{A}{\pi}}$

Step-by-step explanation:

we know that

The area of the circle is equal to

$A=\frac{1}{4}\pi D^{2}$

where

D is the diameter of the circle

Solve for D

That means-----> Isolate the variable D

Multiply both sides by 4 to remove the fraction

$4A=\pi D^{2}$

Divide both sides by π

$\frac{4A}{\pi}=D^2$

square root both sides

$\sqrt{\frac{4A}{\pi}}=D$

Rewrite

$D=\sqrt{\frac{4A}{\pi}}$

Simplify

$D=2\sqrt{\frac{A}{\pi}}$

Sladkaya [172]

Answer:

2, 9 , 16 , 23 , 30 ......

Step-by-step explanation:

$a_n = 7n - 5$

$a_1 = 7*1 - 5 = 7-5 = 2\\\\a_2 = 7*2 - 5 = 14 - 5 = 9\\\\a_3 = 7*3 - 5 = 21 - 5 = 16\\\\a_4= 7*4 - 5 = 28 - 5 = 23\\\\a_5= 7*5 - 5 = 35 - 5 = 30$
