Answer:

Sam average speed for the whole journey =  [tex]3\frac{3}{11} mph[/tex]

Step-by-step explanation:

Formula: Speed = [tex]\frac{Distance}{Time}[/tex]

i.e. Time = [tex]\frac{Distance}{Speed}[/tex]

If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours

If he then walked 2x miles at 3 mph, then time for this period =  [tex]\frac{2x}{3}[/tex]hours

Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]

=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]

=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]

=[tex]\frac{3}{\frac{3+8}{12} }[/tex]

=[tex]\frac{3 x 12}{11}[/tex]

=[tex]\frac{36}{11}[/tex]

=[tex]3\frac{3}{11} mph[/tex]

Hence, Same's average speed for the whole journey =  [tex]3\frac{3}{11} mph[/tex]

Answer:

[tex]y = 2 {(x + 2)}^{2} + 62[/tex]

Step-by-step explanation:

vertex form is

[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]

our original equation

[tex]2 {x}^{2} + 8x + 70[/tex]

first we will find the x value using the formula

[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]

plug the value of x back into the original equation to solve for y

[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]

substitute this back into our vertex form and not forgetting the coefficient a = 2

[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

Step-by-step explanation:

The simplification of the given expression [tex](4-5i)(2+6i)-(3-2i)[/tex], we get [tex]-30i^2+16i+5[/tex].

Given expression is:

By applying the multiplication, we get

→ [tex](8-10i+24i-30i^2)-(3-2i)[/tex]

By multiplying the (-) sign into the bracket, we get

→ [tex]8-10i+24i-30i^2-3+2i[/tex]

→ [tex]5+16i-30i^2[/tex]

By arranging the terms, we get

→ [tex]-30i^2+16i+5[/tex]

Thus the answer above is right.

Step-by-step explanation:

Answer:

Step-by-step explanation:

3/4 = 0.75 pound

1 : 0.75 = x : 1

x = 1 * 1 : 0.75

x = 1.33

--------------check

1 : 0.75 = 1.33 : 1

1.33 = 1.33

Answer:

[tex]1 \frac{1}{3}lb \: sausage[/tex]

Step-by-step explanation:

What Iike to do is make it like a ratio.

So you have one pound of sausage per 3/4lb of cheese

[tex] \frac{1lb \: sausage}{( \frac{3}{4} )lb \: cheese} = \frac{sausage}{1lb \: cheese} [/tex]

Then you just make that sausage the subject of the equation by multiplying 1lb cheese to both sides of the equation, and you have your answer.

[tex]1lb \: cheese \times \frac{1lb \: sausage}{0.75 \: lb \: cheese} = sausage[/tex]

Hey there!

(-12) - (+3 - 4 - 10) + (-15)

= -12 - (3 - 4 - 10) - 15

= -12 - (-1 - 10) - 15

= -12 - (-11) - 15

= -12 + 11 - 15

= -1 - 15

= -16

Therefore, your answer should be: -16

Good luck on your assignment and enjoy your day!

The relation between two numbers which shows how much bigger one quantity is than other.

According to question ,

apples/ oranges = 2 / 6                           equation 1

now, substituting the number of apples in equation 1 , we get

9/oranges = 2/6

oranges = 9 * 6 / 2 = 27

Answer:

Equation: y = 3x + 3.80

Cost of each bag: $3.75

Step-by-step explanation:

y = 3x + b

y = $15.05

x = cost of each bag

b = $3.80

3 = # of bags

15.05 = 3x + 3.80

11.25 = 3x

3.75 = x

The equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Total amount paid by Aiden = $15.05

Total amount paid for ice cream =  $3.80

Number of bags of apple = 3

So if x is the amount of each apple bag and y is the total amount paid by Aiden,

So,Cost of apple bags = 3x

And total amount = 3x + 3.8

or y = 3x + 3.8

this is the equation to determine x.

Now since, total amount paid is $15.05

⇒ 15.05 = 3x + 3.8

or,3x = 15.05 - 3.8

or 3x = 11.25

⇒ x = 11.25/3

⇒ x = $3.75

Thus,the equation to determine x is y = 3x + 3.8

and cost of each apple bag is $3.75.
