Answer:

96 miles

Step-by-step explanation:

The distance from the amusement to jack's home is x (mile, x>0)

jack's family went to the amusement park at: 9 + x/60

On the way home, traffic was bad and they drove 20 mph slower than in the morning⇒ they drove: 60 - 20 = 40 mph

they left the amusement park at: 20 - x/40

have the following equation:

(20 - x/40) - (9+ x/60) = 7

⇔ 4 = x/40 + x/60

⇔ x = 96

so the distance from the amusement park to jack's home is 96 miles

Answer:

x = 8

Step-by-step explanation:

Step-by-step explanation:

in my opinion

2(4x-5)-2=-4

=2×4x-2×5-2=-4

8x-10-2=-4

8x=-4+10+2

8x=-4+12

8x=-16(divide both sides by 8)

×=2

Answer:

sin2x = [tex]\frac{30}{34}[/tex]

Step-by-step explanation:

Given

tanx = [tex]\frac{3}{5}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a right triangle with legs 3 and 5

Let the hypotenuse be h , then using Pythagoras' identity

h² = 3² + 5² = 9 + 25 = 34 ( take the square root of both sides )

h = [tex]\sqrt{34}[/tex]

Thus

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{\sqrt{34} }[/tex]

cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{5}{\sqrt{34} }[/tex]

Hence

sin2x = 2sinxcosx = 2 × [tex]\frac{3}{\sqrt{34} }[/tex] × [tex]\frac{5}{\sqrt{34} }[/tex] = [tex]\frac{2(3)(5)}{\sqrt{34}(\sqrt{34}) }[/tex] = [tex]\frac{30}{34}[/tex]

Answer:

0.96 + 0.43v

Step-by-step explanation:

You simplify, v and -0.57v are like terms, therefore you can add them together

v - 0.57v = 0.43 v

Answer:

0.96 + 0.43v

Step-by-step explanation:

What you are doing is combining like terms. Let's say v is candy I have v - .57v that means I have one candy and I ate .57 of it already so we subtract to get .43v and the .96 is brussel sprouts. We do NOT want to mix the candy and the brussel sprouts because they are different things.

If you need me to explain more let me know, but hopefully this helps and have a great day!

Answer:

4778.36

Step-by-step explanation:

Answer:

4.93 seconds

Step-by-step explanation:

The height y in feet of water t seconds after its release is given by the equation as follows :

[tex]y=-16t^2-2t+400[/tex]

We need to find the taken taken for the water to reach the ground. When it reach the ground, y will be equal to 0. So,

[tex]-16t^2-2t+400=0[/tex]

Above is a quadratic equation whose solutions can be calculated as follows :

[tex]t=\dfrac{-(-2)\pm \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=\dfrac{-(-2)+ \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}, \dfrac{-(-2)- \sqrt{(-2)^2-4\times (-16)\times 400} }{2\times (-16)}\\\\t=-5.062\ s\ \text{and}\ 4.93\ s[/tex]

Neglecting negative value.

Hence, it will take 4.93 seconds for the water to reach the ground

Answer:

$0.014

Step-by-step explanation:

Given that :

Sales price of 33-pound bag of oranges = $3.60

Sales price of 55-pound bag of oranges = $5.25

Price per pound of 33-pound bag:

Sales price / number of pounds

= $3.60 / 33

= $0.109 per pound

Price per pound of 55-pound bag:

Sales price / number of pounds

= $5.25 / 55

= $0.095 per pound

Difference in price per pound of 33-pound bag and 55-pound bag of oranges :

$0.109 - $0.095

= $0.014

Step-by-step explanation:

Answer:

the value of x is 5/7 which is in fraction

Answer:  x = 5/7

Step-by-step explanation:  2x/3 + x/2 =5/6

To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.

for 2x/3  6÷3=2  2×2x=4x so that becomes 4x/6

for x/2    6÷2=3  3× (invisible) 1 = 3x, so that becomes 3x/6

combine 4x/6 + 3x/6 = 7x/6  

Back to the original equation, substituting the calculated term:

7x/6 = 5/6   Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"

7x = 5 .  Divide both sides by 7 to solve for x  7x/7 = 5/7

x = 5/7

Answer:

D- 224

Step-by-step explanation:

10% of 140 is 14

So then you multiply 14 by 6 to get 60%

then you add that to 140 to equal 224.

The correct statement is that if the sales of burgers at Nick's Burgers increases by 60%, the total sales per day will be increased to 224 burgers per day from 140 burgers per day.

An increase in sales refers to as the positive shift in the sales of goods as compared to previous sessions during a given period of time, given that other factors vary.

The increase in sales will happen as a result of the strategies that may have been adopted by Nick or increase in the demand due to external factors.

The calculation of increased no. of burgers sold per day can be calculated by using the formula and putting the values given in the example as below,

increased sales  = 224

So, the new sales of burgers per day is calculated as 224 per day.

Hence, an increase in sales of burgers at Nick's by 60% will result in sales of 224 burgers per day from 140 burgers per day.
