Answer: [tex]171.4\%[/tex]

Step-by-step explanation:

Given

Time is extended from 28 days to 76 days

The percentage increase is given by

[tex]\Rightarrow \dfrac{\text{New-original value}}{\text{original value}}\times 100[/tex]

Putting values

[tex]\Rightarrow \dfrac{76-28}{28}\times 100=\dfrac{48}{28}\times 100\\\\\Rightarrow 171.4\%[/tex]

Thus, the percentage increase in time is [tex]171.4\%[/tex]

Answer:

x + 5, angle G is 16 degrees and angle F is

Step-by-step explanation:

3x + 11 = 5x - 9

3x + 10 = 5x

10 = 2x

x = 5

5(5) - 9 = 16

3(5) + 11 = 26

Answer:

k = 5

Step-by-step explanation:

The standard form of an equation representing proportionality is

y = kx ← k is the constant of proportionality

y = 5x ← is in standard form

with k = 5

Step-by-step explanation:

Answer: A) multiply the input by 6.

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

12÷2=6

36÷6=6

48÷8=6

54÷9=6

72÷12=6

so that means you have to multiply the input by 6.

Answer:

False

Step-by-step explanation:

3 over 3 is equal to 1. So 1 multiplied to 1 over 3 would equal 1/3.

Answer:

y = 2x+14

Step-by-step explanation:

So first of all simplify 2(x+2)

Result is 2x+4

Y-10=2x+4

Now add 10 to both sides and that's how you get your answer

Answer:

its A and i am sure her is the explanation

Step-by-step explanation:

Answer:

a)  (2 x 1000) + (5 x 100)

b)  5^4 × 2²

c)  ??

Step-by-step explanation:

b) 2500 = 25 x 100

25 = 5 x 5

100 = 25 x 4 = 5 x 5 x 2 x 2

Answer:

the third one (2,-18)

Step-by-step explanation:

Answer:

9 1/2

Step-by-step explanation:

=2*3+3 1/2

=6+3+1/2

=9 1/2

Answer:

Width __6___ cm

Length __12__ cm

Step-by-step explanation:

hello :

x : the width   and y : Length    P : the  perimeter

P=2(x+y )        but : P=36cm  and : y = 2x

36 = 2(x+2x)

36 = 2(3x)

6x =36   so : x=6 cm   and y = 2×6=12cm

Step-by-step explanation:

If breadth is b,then length will be 2b,so

Perimeter=36

2(2b+b)=36

3b=18

b=6,so,l=2×6=12

So,length is 12 and breadth is 6,

Hope it helps…

Answer:65.15

Step-by-step explanation:

Answer:

$67.15

Step-by-step explanation:

100% - 15% = 85%

original price = 79

85% of 79 = sale price

85/100 * 79 = sale price

Answer:

x = -56

Step-by-step explanation:

0.75(x + 20) = 2 + 0.5(x - 2)

0.75x + 15 = 2 + 0.5x - 1

0.25x = -14

x = -14/0.25

x = -56

Answer:

105in²

Step-by-step explanation:

Surface area is the total area of the faces.

The faces of pyramid consist of triangles and a square

The area of a square can easily be calculated by squaring the side length

the square of this pyramid has a side length of 5

so

area of square = 5²

5² = 25

the area of the square is 25in²

Now to find the area of the triangles

All we have to do is find the area of one triangle and multiply that buy 4 ( because there are four triangle)

the area of a triangle can be calculated using this formula :

[tex]A=\frac{bh}{2}[/tex]  where b = base and h = height

The triangles have a base length of 5 in and a height of 8 in

so

[tex]A=\frac{5*8}{2} \\5*8=40\\\frac{40}{2} =20\\A=20[/tex]

So the area of one triangle is 20 in²

Now we multiply 20 by 4 to find the area of all 4 triangles

20 * 4 = 80

So the total area of the triangles is 80in²

Finally we add the two areas together

Surface area = 80 + 25

80 + 25 = 105

Hence, the surface area is 105in²

Answer:

105 in.

Step-by-step explanation:

To find the area of a square pyramid, use this formula

a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height.

The base is a square.

To find the area of a square, simply multiply the side length by itself twice (x^2).

5 x 5 = 25.

25 is the area of the base.

a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height

25 + 1/2 ⋅ p ⋅ height.

To find the perimeter of a square, add every side length; the sum is the perimeter.

5 + 5 + 5 + 5 = 20.

20 is the perimeter of the square.

a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height

25 + 1/2 ⋅ 20 ⋅ height

The height is the number along the little lines.

8 is the height.

Now that we have all parts of the formula, we have our final equation.

a (area of base) + 1/2 ⋅ p (perimeter of base) ⋅ height

25 + 1/2 ⋅ 20 ⋅ 8 = 105.

105 in. is the surface area of the square pyramid.
