A company charges $7 for a T-shirt and ships any order for $15. A school principal ordered a number of T-shirts for the school s

tore. The total cost of the order was $1,520. Which equation can be used to find the number of shirts ordered?

7x + 15 = 1520
It’s $7 times the unknown number of shirts (x). Plus $15 to ship. All has to equal the total of $1,520.

Answer:

See below

Step-by-step explanation:

Use the formulae directly

For a cone, with base radius = r and height = h, here are the related formula

$\textrm{Slant height l} = \sqrt{r^2 + h^2}$ (1)

$\textrm{Lateral surface area} = \pi r l$

$\textrm {Base area} = \pi r^2$

$\textrm { Total Surface Area SA} = \textrm{Base Area + Lateral Area} = \pi r^2 + \pi rl = \pi r(r + l)$ (2)

$\textrm{Volume V = } (1/3) \pi r^2h$ (3)

Therefore directly plugging in the numbers in the above equations:

Note:

l = slant height in cm
SA = total surface area in sqcm
V = Volume in cubic cm

Figure(a)

r = 4, h = 8

$\textrm{l} = \sqrt{4^2 + 8^2} =\sqrt{80} = 8.944 \\\textrm{SA} = 4\pi(4 + 8.944) = 4\pi(12.944) = 162.66\\\textrm{V} = (1/3)\pi(4^2)(8) = 134.04$

Figure(b)

r = 7, h =15

$\textrm{l} = \sqrt{7^2 + 15^2} =\sqrt{274} = 16.55$

$\textrm{SA} = 7\pi(7 + 16.55) = 517.89$

Figure (c)

r = 5, l = 8

$h = \sqrt{l^2 - r^2} = \sqrt{8^2 - 5^2} = \sqrt{39} = 6.245\\SA = \textrm{SA} = 5\pi(5 + 8) = 204.2\\V = (1/3)\pi(5^2)(6.245) = 163.5$

I think it’s 309 cm because each side is 1 cm, there’s 3 sides, and 103 triangles. so 103x3=309 sides which means 309 cm

Given the equation kx – 17 = 51 + x, where k=1, solve for X.

IgorC [24]

Answer:

No solution for x, when k = 1
x = 68/(k - 1), when k≠ 1

Step-by-step explanation:

<u>Given the equation</u>

kx – 17 = 51 + x, where k = 1,

<u>Solve for x:</u>

1*x - 17 = 51 + x
x - 17 = x + 51
x - x = 51 + 17
0 = 68,

Incorrect equation, no solution for x when k=1

<u>Solving for x when k ≠ 1</u>

kx - 17 = 51 + x
kx - x = 51 + 17
x(k - 1) = 68
x = 68/(k - 1)
