Answer:

50

Step-by-step explanation:

20+20=40

5+5=10

40+10=50

Answer: P=50

Step-by-step explanation: 20 m = length and 5 m = width

Solution:

P=2(l+w)=2·(20+5)=50

So the perimeter is 50

Answer:

x > 3/2

Step-by-step explanation:

2x - 3 > -4x + 6

Add 4x to each side

2x+4x - 3 > -4x+4x + 6

6x-3 > 6

Add 3 to each side

6x-3+3>6+3

6x>9

Divide each side by 6

6x/6 >9/6

x > 3/2

Answer: 476m²

Step-by-step explanation:

Find the area of the triangle and then subtract it from the area of the rectangle.

Area of triangle = 1/2 * base * height

= 1/2 * 8 * 6

= 24m²

Area of rectangle:

= Length * Width

= 25 * 20

= 500m²

Area not covered by garden:

= 500 - 24

= 476m²

Answer:

The inverse of

y

=

2

x

is

y

=

log

2

x

Explanation:

This is how to do it.

From the given

y

=

2

x

interchange the variables so that

x

=

2

y

then solve for y:

x

=

2

y

take the logarithm of both sides with base

=

2

log

2

x

=

log

and

y

=

x

The graph of

y

=

graph{(y-2^x)(y-log x/log 2)(y-x)=0[-20,20,-10,10]}

Answer:

x = 1.75

Step-by-step explanation:

Given

3.5(2.25 + x) = 14 ( divide both sides by 3.5 )

2.25 + x = 4 ( subtract 2.25 from both sides )

x = 1.75

Answer:

24m²

Step-by-step explanation:

..,.................

Area = 5*4+2*1+2*1

Area = 20+2+2

Area = 24m²

Answer:

24 m^2

Step-by-step explanation:

We need to study the structure well

We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle

Then we remove the area of the four squared cut out from the big rectangle.

Total length of the rectangle is 5+1+1=7m

Then the length of the breath of the rectangle is 2+1+1=4m

So area of rectangle is given as length × breadth

Area= l×b

Area=7×4=28m²

Area of the big rectangle is 28m²

Then the squared is made of dimension 1m by 1m

Area of a square is s²

Then, a=1m

Area of the square= 1²=1m²

There are four squared side

Then, the total area of the four squared is 4×1=4m²

Then the required area is

Area=Total area - area of four squared side

Area=28m²-4m²

Area =24m²

Area of the figure is 24m²

The correct option is A.

Answer:

34

Step-by-step explanation:

Because it is a mixed fraction, it tells us the whole number already. After that, we need to look at the actual fraction part and decide if it's large enough to round the whole number up. 1/8 is not, so we keep the whole number at 34

Answer:

That would be 34

Hey,I'm not sure enough...i guess if the highest power is 9 then we get 9 roots..sorryvif I'm wrong:')

Answer: 15 √ 2

Step-by-step explanation:

Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.

You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3

10√6 / 2 * √ 3 = 15 √ 2

The decimal form: 21.2

Answer: 1420

Step-by-step explanation:

Answer:

7 + L + 3 = L + 10

Step-by-step explanation:

Answer:

m = 2

Step-by-step explanation:

∠ GLI = 90°

∠ GLH + ∠ HLI = ∠ GLI , that is

9m + 25m + 22 = 90

34m + 22 = 90 ( subtract 22 from both sides )

34m = 68 ( divide both sides by 34 )

m = 2

Then

∠ HLG = 9m = 9 × 2 = 18°

Answer:

8.23 × 10^8

Step-by-step explanation:

count how many spaces there are between the first number and the last number. standard form is between 1-10

Step 1: Set up a table.

Algebra Age Problems

Step 2: Fill in the table with information given in the question.

John is twice as old as his friend Peter. Peter is 5 years older than Alice. In 5 years, John will be three times as old as Alice. How old is Peter now?

Let x be Peter’s age now. Add 5 to get the ages in 5 yrs.

Algebra Age Problems

Write the new relationship in an equation using the ages in 5 yrs.

In 5 years, John will be three times as old as Alice.

2x + 5 = 3(x – 5 + 5)

2x + 5 = 3x

Isolate variable x

x = 5

Answer: Peter is now 5 years old.

Hi there!

8 would be the nearest ten of 7.995..

1.Multiply 82 with 0.01:

[tex]82[/tex]·[tex]0.01=0.82[/tex]

2.Multiply the terms:

[tex]0.82[/tex]·[tex]9.75=7.995[/tex]

3.Round the term:

[tex]7.995=8[/tex]

Therefore, 82% of 9.75 in nearest tenth is 8.
