Which expression is equivalent to 2(a+3) when a=3?
O 2(3)
05(3)
O 2(3)+3
O 2(3)+6

Answers

Answer 1

Answer:

The answer is 2(3)+6

Step-by-step explanation:

The perenthesis means multiplication so you would first do 2 times three which is 6 and then 6+6=12 and the first expresion is 2(a+3) a=3 to solve that you would do whats in the perenthesis 3+3 which equals 6 and then the 6 in the perenthesis means mulitplication. so then you would do 2 times 6 and get 12. so the 3rd one is the answer.

A pilot of a helicopter plans to release a bucket of water on a forest fire. The height y in feet of water t seconds after its release is modeled by y = − 16 t 2 − 2 t + 400 . How long will it take for the water to reach the ground? Round to one number after the decimal point.

Answers

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

Will mark brainlist!! Nick’s Burgers is a fast-food restaurant that sells 140 burgers a day. If sales increase by 60%, how many burgers does the restaurant sell in a day?

A.56
B.148
C.200
D.224

Answers

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.

What is Increased Sales?

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.

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]

Please solve for x as a fraction!

Answers

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

Jack's family left home at 9:00 AM and drove to the amusement park at 60 mph. They spent 7 hours at the park and then drove back home. On the way home, traffic was bad and they drove 20 mph slower than in the morning. They got home at 8:00 PM. How far is the amusement park from Jack's home?

Answers

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

I promise this the last one but how do you do these type of problems?

Answers

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.
