Answer:

A. 75

Step-by-step explanation:

to get the average mark multiply the result by it's associated weight

93 × 10% = 9.3

82 × 30% = 24.6

72 × 40% = 28.8

60 × 20% = 12

then add these numbers to get his average 74.7 which is closest to 75

timofeeve [1]

Answer:

6.1 m

Step-by-step explanation:

Always draw a diagram! And now pythagorean theorem. a^2 + b^2 = c^2

Substitution:

a^2 + 2.8^2 = 6.7^2

a^2 + 7.84 = 44.89

a^2 = 37.05

a = 6.086...

Rounding <u>up</u> to one decimal point, thats 6.1 m

Special Right Triangles: Decimal Answer ! What’s H and C ?! Help me please?! Round to the nearest tenth.
lesantik [10]

Answer:

h = 1.41

c = 3.46

Step-by-step explanation:

See the triangles diagram attached.

For the first triangle, Base = h, Hypotenuse = 2 and the angle between base and hypotenuse is 45°.

Therefore, \cos 45 = \frac{\textrm {Base}}{\textrm {Hypotenuse}} = \frac{h}{2}

⇒ h = 2 \cos 45 = \frac{2}{\sqrt{2} } = \sqrt{2} = 1.414 = 1.41 (Answer)

{Rounded to the nearest tenth}

Again in the second triangle, Perpendicular = c, Hypotenuse = 4 and the angle between base and hypotenuse is 60°.

Therefore, \sin 60 = \frac{\textrm {Perpendicular}}{\textrm {Hypotenuse}} = \frac{c}{4}

⇒ c = 4 \sin 60 = \frac{4 \times \sqrt{3} }{2} = 2\sqrt{3} = 3.46 (Answer)

{Rounded to the nearest tenth}

Find the volume of the cone
arlik [135]

Answer:

314.2 cm³

Step-by-step explanation:

Volume of a cone =  \frac{1}{3}  \times \pi \times  {r}^{2}  \times h

The volume of the cone

=  \frac{1}{3}  \times \pi \times  {5}^{2}  \times 12

= 314.15926...

= 314.2 cm³ (rounded to the nearest tenth)
