Answer: You will pay $13.52 for this shirt.

Step-by-step explanation: 0.9435

Since the tax is 7.5%, you have to multiply 12.58 by 7.5% to find the amount of money paid as tax.

7.5% = 0.075

12.58 x 0.075 = 0.9435

Since we are dealing with money we have to round to the nearest hundredth -- 0.9435 = 0.94

Then to find the final cost of the shirt, we have to add 12.58 and 0.94 to get $13.52.

Answer:

x = 9.8

Step-by-step explanation:

to find x, use pythagorean theorem

$a^{2} = c^{2} - b^{2}$

$a^{2} = 14^{2} - 10^{2}$

$a^{2} = 196 - 100$

$a^{2} = 96$

$\sqrt{a^2} = \sqrt{96}$

$a = 9.7979$ ⇒ 9.8

Really confusing......

valina [46]

Answer:

She spent 40 more dollars or to be exact 40.70 dollars more then aiden

Step-by-step explanation:

Aiden bought 60 candles.

0.37*60 is equal to $22.20

Aidens sister bought 170 candles at same price of $0.37

0.37*170=$62.90

Now subtract

$62.90-22.20=$40.70

She spent 40 more dollars or to be exact 40.70 dollars more then aiden

Two equivalent expressions have the same _____ even though they may be written in different ways.

Svetach [21]

Answer:

Value

Step-by-step explanation:

Value because order can be different and they can still be the same!

For example, 3x+2 = 2+3x different order but still are equivalent!

x = -2/3, so their values are equivalent!

Hope this helps!

Work out the surface area of a cylinder when the height = 18cm and the volume = 1715cm cubed

lara [203]

Answer:

813.4 cm² (nearest tenth)

Step-by-step explanation:

Volume of a cylinder

$\sf V=\pi r^2 h \quad\textsf{(where r is the radius and h is the height)}$

Given:

h = 18cm
V = 1715 cm³

Use the Volume of a Cylinder formula and the given values to find the radius of the cylinder:

$\implies \sf 1715=\pi r^2 (18)$

$\implies \sf r^2=\dfrac{1715}{18 \pi}$

$\implies \sf r=\sqrt{\dfrac{1715}{18 \pi}$

Surface Area of a Cylinder

$\sf SA=2 \pi r^2 + 2 \pi r h \quad\textsf{(where r is the radius and h is the height)}$

Substitute the given value of h and the found value of r into the formula and solve for SA:

$\implies \sf SA=2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)^2 + 2 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)(18)$

$\implies \sf SA=2 \pi \left(\dfrac{1715}{18 \pi} \right) + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)$

$\implies \sf SA=\dfrac{1715}{9} + 36 \pi \left(\sqrt{\dfrac{1715}{18 \pi}\right)$

$\implies \sf SA=813.3908956...$

Therefore, the surface area of the cylinder is 813.4 cm² (nearest tenth)
