Answer:

16m/s

Step-by-step explanation:

Given data

u = 40,

a = - 6,

t = 4

Let us substitute into the given expresssion to find v

v = u + at

v = 40+ -6*4

v= 40+ (-24)

v= 40-24

v= 16m/s

Answer:

Width = 12

Step-by-step explanation:

L = k/w

Where,

L = length of the rectangle

w = width of the rectangle

k = constant of proportionality

length is 2 and the width is 42

L = k/w

2 = k/42

k = 42 × 2

k = 84

calculate the width of a rectangle whose length is 7.

L = k/w

7 = 84/w

7w = 84

w = 84/7

w = 12

Width = 12

Answer:

3x/2 + 3y

Step-by-step explanation:

Given the expression 1/4 ( 3x + 4y ) + 3 ( 1/4 x + 2/3 y)

Open the parentheses

= 1/4(3x) + 1/4(4y) + 3(1/4x) +3(2/3y)

= 3/4 x + y + 3/4 x +2y

Collect like terms

3/4 x +3/4 x +y+2y

6/4 x + 3y

3x/2 + 3y

Hence the correct expression is 3x/2 + 3y

Answer:

7 in

Step-by-step explanation:

volume of a rectangular prism = width x height x length

width x length = area of the base

the sea shell box

200 = width x length x 5

width x length = 200/5 = 40cm^2

rock box

280 = 40in^2 x height

height = 280/40 = 7 in

Here is the complete question

Priscilla has some grapes that she wants to give to her friends. She wants to give 1/4 of a kilogram of grapes to each friend. If Priscilla has 6 kilograms of grapes, to how many friends can she give grapes?

Number of friends she can give grapes to = total kilograms / kilogram she wants to give to each friend

6 ÷[tex]\frac{1}{4}[/tex]

6 x 4 = 24 friends

Answer:

5xX - 3x^2 - 2X + 6x - 21

Step-by-step explanation:

x(5x-2)-3(x^2-2x+7) =

5x^2-2x-3(x^2-2x+7)

=

5x^2-2x-3x^2+6x-21

=(combine the like terms)

2x^2-2x+6x-21

=

2x^2+4x-21

Answer:

y=-x-8

Step-by-step explanation:

2x+2y=-16

2x+2y+16=0

2x+16=-2y

x+8=-y

-x-8=y

Answer:

6.25%

Step-by-step explanation:

% change= (chnage/original salary) × 100%

Change = new salary - original salary

Hence = 3400-3200=200

% change= (200/3200)×100%= 6.25%

Answer:

10218.75

Step-by-step explanation:

You should divide the two shapes into a rectangle and a triangle, find the area of each, then add them together like so:

For the rectangle:

37.5*22.5 = 843.75

For the triangle:

To find the base: 75 - 37.5 = 37.5

To find the height, use pythagoream theorem.

62.5² = 37.5² + b²

3906.25 = 1406.25 + b²

3906.25 - 1406.25 = 2500

√2500 = 50.

The height is 50, so 50*37.5(1/2)

= 937.5

Now add them together

937.5 + 843.75

Answer:

sin(θ) = 0.86602540378

Step-by-step explanation:

To find the value of theta, we need to find do the acos of it

θ = acos(1/2)

θ = 60

and then you find sin(60)

sin(60) = 0.86602540378

Answer:

Alternate Interior angles

Alternate Interior angles are angles that are within two parallel lines.

So for the above question, our pairs of Alternate Interior angles are:

= Angle 4 and Angle 6

Angle 3 and Angle 5

Alternate exterior angles

Alternate exterior angles are angles that are found outside the two parallel lines

For our above question, our pairs of Alternate exterior angles are:

= Angle 1 and 7

Angle 2 and Angle 8

Corresponding angles

= Angle 1 and Angle 5

Angle 2 and Angle 6

Angle 4 and Angle 8

Angle 3 and Angle 7

Step-by-step explanation:

Alternate Interior angles

Answer:

x can be -2

Step-by-step explanation:

Let

f(x)=x+2

x+2=0

x= -2

Answer:

x = -2

Step-by-step explanation:

subtract 2 both sides x-2 0-2

first side left with x

second side -2

so your left with x=-2

Answer:

Step-by-step explanation:

Amount she gets in a day = number of flower * cost of each flower

                   = (25x² +5x + 5)*5x

                  = 25x²*5x + 5x *5x  + 5*5x

                  = 125x³ + 25x² + 25x

Amount she gets in 5 day = (125x³ +25x² + 25x)* 5

                                           = 125x³*5 + 25x² *5 + 25x *5

                                          = 625x³ + 125x² + 125x
