Answer:

2.35 hrs

If she merged the highway at 1 pm, then she'll leave the highway by 3:21 pm

Step-by-step explanation:

distance traveled = 94 miles

cruise speed = 40 mph

time taken = ?

time taken = distance/speed = 94/40 = 2.35 hours

2.35 hrs = 2 hrs + (0.35 x 60) = 2 hrs + 21 min

If she merged the highway at 1 pm, then she'll leave the highway by 3:21 pm

(-13, -12)

Step-by-step explanation:

The midpoint (x,y) between two points ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) on the coordinate plane is given by:

[tex]x=\frac{x_1+x_2}{2};\\\\y=\frac{y_1+y_2}{2}[/tex]

Hence given that house A is at (3, 6) and house B is at (-5, -3). Since house B is placed at the middle of house A and house B, let the coordinates of house C be ([tex]x_2,y_2[/tex]). Hence:

[tex]-5=\frac{3+x_2}{2\\} \\3+x_2=-10\\\\x_2=-10-3\\\\x_2=-13[/tex]

[tex]-3=\frac{6+y_2}{2\\} \\6+y_2=-6\\\\y_2=-6-6\\\\y_2=-12[/tex]

Therefore house C is at (-13, -12)

Answer:

x = 1.5

Step-by-step explanation:

First, we distribute (get rid of parentheses):

6x - 3 - 3x = 5 - x - 2

Then, we simplify:

3x - 3 = 3 - x

Then, we combine like terms:

3x + x = 3 + 3

Then, we simplify again:

4x + 6

Finally, we divide 4 on both sides:

We got x = 1.5

Answer:

36

Step-by-step explanation:

(x + 6)(x+6)

F.O.I.L.

x^2 +6x + 6x + 36

X^2 + 12x + 36

Answer:

36

Step-by-step explanation:

● x^2 + 12x

● 1 × x^2 + 2 × 1 × 6 × x

Notice that the third term is 6

So we will add 36 (6^2)

● x^2 + 12x + 36

● (x+6)^2

Answer:

b = (A - lw) / 0.5h

Step-by-step explanation:

The formula for area of the enclosed place is

A=lw+0.5bh

Where,

A= Area of the enclosed space

l= length of the rectangle

w= width of the rectangle

b= base of the triangle

h= height of the triangle

A=lw+0.5bh

Solve for b

A=lw+0.5bh

Subtract lw from both sides

A - lw = lw + 0.5bh - lw

A - lw = 0.5bh

Divide both sides by 0.5h

(A - lw) / 0.5h = (0.5bh) / 0.5h

(A - lw) / 0.5h = b

Therefore,

b = (A - lw) / 0.5h

Answer:

b= A-lw over 0.5h

Step-by-step explanation:

Step-by-step explanation:

(x+4)3=2

3x+12=2

3x=-12+2

3x=-10

divide both sides by 3

x=-10/3

Answer:

The distance Maria walked is 75 ft.

Total displacement from her starting point is 35 ft east.

Step-by-step explanation:

Consider the sketch below.

The distance travelled can be obtained by adding all the distances walked in different directions.

This is 20ft +35 ft +20ft = 75ft

The distance Maria walked is 75 ft.

The displacement of an object refers to the distance travelled in a specified direction.

We noticed that maria moved 20ft north, then 35 ft east, only to come back 20 ft south again.

This means her total displacement from her starting point is 35 ft east. this is because her north and south movements cancelled out each other.

Answer:

$2.040

Step-by-step explanation:

Para calcular la cantidad que fue abonada en realidad, debes encontrar el valor del descuento calculando el 15% del valor total de la compra y este resultado se debe restar del total:

$2.400*15%= $360

$2.400-$360= $2.040

De acuerdo a esto, la cantidad abonada en realidad es: $2.040.

The width of the rectangular base of the pyramid is W = 3 centimeters

The volume of a pyramid, is the product of the area of its base with the height of the pyramid, and divide by 3. We express this product with the formula V = ( 1/3) ×B×h, where B is the area of the base of the pyramid, and h is its height.

Volume of Pyramid = ( 1/3 )a²H

Given data ,

Let the volume of the pyramid be represented as V

Now , the value of V is

V = 105 cm³

And , the length of the pyramid L = 7 cm

The height of the pyramid is H = 15 cm

Let the width of the pyramid be W

And , Volume of Pyramid = ( 1/3 ) ( L x W x H )

105 = ( 1/3 ) ( W x 15 x 7 )

On simplifying , we get

105 ( W ) ( 1/3 ) = 105

Divide by 105 on both sides , we get

W / 3 = 1

Multiply by 3 on both sides , we get

W = 3 cm

Therefore , the value of W is 3 cm

Hence , the width of pyramid is 3 cm

Answer:

Amount of NaCl = 23.376 gram

Step-by-step explanation:

Given:

Molarity = 4M

Volume of solution = 100 ml

Find:

Amount of NaCl

Computation:

Molar mass of Na = 22.99 g/mole

Molar mass of Cl = 35.45 g/mole

Molar mass of NaCl =  22.99 + 35.45

Molar mass of NaCl  = 58.44 g/mole

Molarity = [moles of solute / volume of solute(ml)]1,000

4 = [moles of solute / 100]1000

Moles of solute = 0.4

moles of solute = Mass of solute / molar mass

0.4 = Amount of NaCl / 58.44

Amount of NaCl = 23.376 gram
