Answer:

There was a 24% decrease

Step-by-step explanation:

Percentage decrease = (final season's score - semi-final score) / semi final score x 100

\frac{95-125}{125} ×100

\frac{-30}{125} × 100 = -24%

A ship sails 20km due North and then 35km due East .How far east is it from its starting point?
atroni [7]

Use the Pythagoras' Theorem:

A^2 + B^2 = C^2

20^2 + 35^2 = C^2

400+ 1225=1625=C^2

square root of 1625= C = 40.31 km

If triangle CAT is similar to triangle DOG, which of the following statements is incorrect?
jeyben [28]

Answer:

1. triangle TCA ~ triangle GOD

4. If TC/GD=3/2, then m<T/m<G=3/2.

Step-by-step explanation:

<u><em>The statements of the question are</em></u>

1. triangle TCA ~ triangle GOD

2. AT: OG= AC:OD

3. If TC/GD=3/2, then AC/OD=3/2.

4. If TC/GD=3/2, then m<T/m<G=3/2.

5. If the scale factor of triangle CAT to triangle DOG is 3 to 2, then the scale factor of triangle DOG to triangle CAT is 2 to 3.

6. If AC is twice as long as AT, then OD is twice as long as OG

<u><em>Verify each statement</em></u>

1) triangle TCA ~ triangle GOD

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

triangle CAT ~ triangle DOG -----> is given

so

Reorder

Corresponding sides are named using pairs of letters in the same position on either side of the congruence statement

triangle TCA ~ triangle GDO

therefore

The statement is not correct

2). AT: OG= AC:OD

we know that

If two triangles are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

In this problem

triangle CAT ~ triangle DOG -----> is given

so

Applying proportion

\frac{AT}{OG}=\frac{AC}{OD}=\frac{TC}{GD}

The statement is true

3). If TC/GD=3/2, then AC/OD=3/2.

we have that

\frac{AT}{OG}=\frac{AC}{OD}=\frac{TC}{GD} ---> see part 2)

so

\frac{TC}{GD}=\frac{AC}{OD}

therefore

The statement is true

4). If TC/GD=3/2, then m<T/m<G=3/2

Remember that

In two similar triangles, corresponding angles are congruent

so

m\angle T=m\angle G

m\angle T/m\angle G=1

therefore

The statement is false

5). If the scale factor of triangle CAT to triangle DOG is 3 to 2, then the scale factor of triangle DOG to triangle CAT is 2 to 3

we know that

If the scale factor of triangle CAT to triangle DOG is a/b. then  the scale factor of triangle DOG to triangle CAT is b/a

The scale factor will be the reciprocal

therefore

The statement is true  

6). If AC is twice as long as AT, then OD is twice as long as OG

we know that

\frac{AT}{OG}=\frac{AC}{OD}

Reorder

\frac{AT}{AC}=\frac{OG}{OD}

If AC is twice as long as AT ----> AC=2AT

If OD is twice as long as OG ----> OD=2OG

substitute

\frac{AT}{2AT}=\frac{OG}{2OG}

simplify

\frac{1}{2}=\frac{1}{2} ----> is true

therefore

The statement is true

Degree Of Length Degree Of Width Degree Of Height Degree Of Volume
Andrew [12]

Answer: length = 1, width = 1, height = 3, volume = 5

<u>Step-by-step explanation:</u>

Degree is the biggest exponent for the variables in the expression

Length = 4x - 1. The exponent for x is 1 --> degree = 1

Width = x          The exponent for x is 1  --> degree = 1

Height = x³       The exponent for x³ is 3  --> degree = 3

Volume = 4x⁵ - x⁴.  The biggest exponent for x is 5  --> degree = 5
