Answer:

17 feet

Step-by-step explanation:

A right angle has 3 sides: the adjacent, the opposite and the hypotenuse.

The hypotenuse is the largest side of the right angle

The shorter sides are 15 feet and 8 feet which should represent opposite and adjacent sides respectively

Opposite = 15 feet

Adjacent = 8 feet

Hypotenuse = x feet

Using Pythagoras theorem to solve

Hypotenuse ² = opposite ² + adjacent ²

x² = 15² + 8²

x² = 225 + 64

x² = 289

Find the square root of both sides

√x² = √289

x = 17 feet

The 3rd side is 17 feet

Answer:

3x - x + 3 - 9 = 6

3x - x + 3 = 6 +9

2x +3 = 15

2x = 15 - 3

2x = 12

x= 12/2

x= 6

Rules - When the side changes , sign changes .for ex (-9) on changing side (from left to right ) becomes plus 9

p=2(l+b) =2(3x-3) =6x=48=x=8

Answer:

1 and 19

Step-by-step explanation:

I believe this is a factoring problem.

Example:

If we have the equation x^2-2x-3

We can find two numbers that multiply to -3 that add to -2

The two numbers are -3 and 1

(x-3)(x+1)= So x=3 and x=1

Answer:

1 and 19

Answer:

47.86%

Step-by-step explanation:

Total number of seats in a movie theater Before a renovation = 117

Total number of seats in a movie theater after a renovation = 173

We need to find the percentage increase of the number of seats. It can be calcualted as :

[tex]\%=\dfrac{\text{|final number-initial number|}}{\text{initial number}}\times 100\\\\=\dfrac{173-117}{117}\times 100\\\\=47.86\%[/tex]

So, the increase in percentage is 47.86%.

Answer:8.5

Step-by-step explanation:

Answer:

step one

find the difference between marked price and the selling price, which is 24-15.50=8.5

step two apply the formula which is, difference divided by marked or original price and then multiple by 100

eg (8.5÷24) × 100= 35.4

so now round off to the nearest percent that's 35%

Hope this helps and have a nice day :)

Answer:

a=3

Step-by-step explanation:

24=3(2a-14)-3a

distribute

24=6a-42-3a

subtract 3a from 6a

24=3a-42

add 42 to both sides

66=3a

divide 3

3=a

a=3

Answer:

C, D and E

Step-by-step explanation:

Given

Represent solid beads with S and clear beads with C

So:

[tex]S:C = 8:20[/tex]

Required

Select operations that give an equivalent ratio

First, we need to get the unit ratio

[tex]S:C = 8:20[/tex]

Divide through by 4

[tex]S:C = 2:5[/tex] -- This means that, after any operation. The equivalent ratio must be 2: 5

Option A: Add 2 to S and 2 to C

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8 + 2 : 20 + 2[/tex]

[tex]S:C = 10 : 22[/tex]

Divide through by 2

[tex]S:C = 5:11[/tex]

Option B: Subtract 8 from S and 6 from C

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8 - 8 : 20 - 6[/tex]

[tex]S:C = 0 : 14[/tex]

Option C: Multiply S and C by 2

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8*2:20*2[/tex]

[tex]S:C = 16:40[/tex]

Divide through by 8

[tex]S:C = 2:5[/tex]

Option D: Divide S and C by 4

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8/2:20/4[/tex]

[tex]S:C = 2:5[/tex]

Option E: Multiply S and C by 18

[tex]S:C = 8:20[/tex]

Perform the operation

[tex]S:C = 8*18:20*18[/tex]

[tex]S:C = 144:360[/tex]

Divide through by 72

[tex]S:C = 144/72:360/72[/tex]

[tex]S:C = 2:5[/tex]

From the calculations above, options C, D and E gave an equivalent of 2:5.

Answer:

Step-by-step explanation:

((3×5)+4)/5=

19/5

The improper fraction is 19/5.

We have to convert [tex]3 \dfrac{4}{5}[/tex]  it into an improper fraction.

To convert into an improper fraction calculation must be done in a single unit following all the steps given below.

                    [tex]= \dfrac{3 \times 5 + 4}{5}[/tex]

                    [tex]=\dfrac{15+4}{5}\\\\=\dfrac{19}{5}[/tex]

Hence, The improper fraction is 19/5.
