1 answer:

3 0

Lateral Area = (π • r • slant height)
If radius = 2 and
slant height = 3 then


Lateral Area = (π * 2 * 3)

The lateral area = 18.8495559215

Nautical flags are used to represent letters of alphabets. The flag for the letter O consists of a yellow right triangle and a r

liraira [26]

Answer:

The length of a side of the flag is 7.2inches

Step-by-step explanation:

Let length = x

Let hypotenuse = x+3

Using Pythagoras' Theorem:

x^2 + x^2 = (x+3)^2

x^2 + x^2 = x^2 + 6x + 9

2x^2 = x^2 + 6x + 9

×^2 - 6x - 9 = 0

$x = \frac{ - b + - \sqrt{ {b}^{2} - 4ac } }{2a}$

x=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)

×=[6+sqrt.72]/2

×=7.2inches

×=[-(-6)+sqrt.(-6)^2-4(1)(-9)]/2(1)

x=[6-sqrt.72]/2

×=-1.2(rej)

(PS. sqrt is square root)

Kameryn types 75 words per minute and is just starting to write a term paper. Joe already has 510 words written and types at a s

AnnZ [28]

Answer:

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Step-by-step explanation:

Let

x -----> the number of minutes

y ----> the total words typed

we know that

Kameryn

$y=75x$ -----> equation A

Joe

$y=60x+510$ -----> equation B

Solve the system of equations by substitution

Substitute equation A in equation B and solve for x

$75x=60x+510$

$75x-60x=510$

$15x=510$

$x=34\ minutes$

That means

For x=34 minutes

The amount of words written by Kameryn and Joe are the same.

therefore

For x > 34 minutes

Kameryn will have more words typed than Joe when the number of minutes exceeds 34.

Natalie works in a department store selling clothing. She makes a guaranteed salary of $300 per week but is paid a commission on

Luba_88 [7]

Answer: Natalie make $ 367.5 in a week in which she made $225 in sales .

Natalie make $ ( 300+x ) in a week in which she made $ x in sales .

Step-by-step explanation:

Base Salary of Natalie = $300

Also, she gets 30% of the her total sales for the week.

If total sales in a week = $225

commission = 30% of $225

= $ ( 0.30 × 225)

= $ 67.5

Natalie got = Base Salary + Commission

= $300 + $ 67.5

= $ 367.5

∴ Natalie make $ 367.5 in a week in which she made $225 in sales .

If total sales in a week = $x

commission = 30% of $x

= $ ( 0.30 × x)

= $ 0.30 x

Natalie got = Base Salary + Commission

= $ ( 300+x )

∴ Natalie make $ ( 300+x ) in a week in which she made $ x in sales .
