On a scale drawing with a scale of 1 cm: 3 m , the height of a tree is 5 cm. How tall is the actual tree?
Neko [114]
In 3 metres there are 300 centimetres. Each centimetre on the scale is 300 centimeters, or a ratio of 1:300. The tree is 5 centimetres on the scale. Each centimeter on the scale is 300 centimetres, therefore 5 centimetres on the scale is 1500 centimetres. 1500 centimetres is equal to 15 metres.

I need help with this ​
Korvikt [17]

Answer:

D.

Step-by-step explanation:

According to converse of the Pythagorean Theorem, that if the square of the third side (longest side) of a triangle equals the sum of the other two shorter sides, therefore, the triangle formed must be a right triangle.

From the side lengths given, the following satisfies the Pythagorean triple:

5² + 12² = 13².

Therefore, the procedure to use to confirm the converse of the Pythagorean Theorem would be to draw the two shortest side, 5 cm and 12 cm, so that a right angle will be between them. The side measuring 13 cm should therefore fit in to form a right triangle.

3c+2d=2;d=4 step by step
mina [271]
Hi there!

3c + 2d = 2 for d = 4
3c + 2(4) = 2
3c + 8 = 2
Subtract 8 to both sides
3c + 8 - 8 = 2 - 8
3c = -6
Divide both sides by 3
3c/3 = -6/3
c = -2

I hope I helped!

An obtuse triangle has angle measurements of 100°, 60°, and 20°. if the longest side of this triangle is 20 feet, what is the le
ValentinkaMS [17]
This is the concept of geometry, we are required to calculate for the length of the shortest side. The shortest side is the side opposite to the smallest angle; Therefore using sine rule we shall have:
a/sin A=b/sinB=c/sinC
let a=20 and A=100
b=x and B=20
thus the shortest side will be given by:
20/sin 100=x/sin 20
x=(20sin 20)/100
x=6.95 feet
The answer is 6.95 feet

Answer: 1200 m

75\ m/min

Step-by-step explanation:

Given

Alex Jogged 3 rounds of 400 m track

It took 16 min to Jog 3 rounds

(a) Total distance Alex had Jogged

\Rightarrow 3\times 400=1200\ m

(b) Average speed is the total distance by the total time

\Rightarrow \dfrac{1200}{16}=75\ m/min
