When he arrived at school how many conks did Billy had left? Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

Answers

Answer: 64 ; $28

Step-by-step explanation:

A. Billy collected 256 conks but lost ¾ of them on his way to school through a hole in his bag. When he arrived at school how many conks did Billy had left?

Number of conks collected by Billy = 256

Fraction lost = 3/4

Amount lost = 3/4 × 256 = 192

Number of conks Billy has left will be:

= 256 - 192

= 64

B. Skateboards cost €36 each in my local store. The shopkeeper says if I buy one I can buy another for only 7/9 of the normal price. How much would a second skateboard cost?

This will cost:

= 7/9 × $36

= 7 × $4

= $28

1) 4 ft

2) Length =69

Width=64

Step-by-step explanation:

1) 2x-2+2x-2+x-2+x-2=x+x-1+x-1

6x-8=3x-2

6x-3x=-2+8

3x=6

x=2

plugging it back in, we get for the triangle

Together teammates Pedro and Ricky got 2689 base hits last season Pedro had 281 more hits than Ricky how many hits does each player have?

Answers

Answer: Ricky has 1204 hits and Pedro has 1485 hits

Explanation:

- Let R be the number of hits that Ricky had
- Let P be the number of hits that Pedro had

R + P = 2689

But Pedro has 281 more hit than Ricky

Thus, P = R + 281

Substitute this value in our first equation

R + R + 281 = 2689
2R + 281 = 2689
2R = 2689 - 281
2R = 2408
R = 2408/2
R = 1204

And P = R + 281

But R = 1204

=> P = 1204 + 281 = 1485

Therefore, Pedro has 1485 base hit and Ricky has 1204 hit.

A rocket is launched from a tower. The height of the rocket, y in feet, is related to the
time after launch, x in seconds, by the given equation. Using this equation, find the
time that the rocket will hit the ground, to the nearest 100th of second.
y = -16x2 + 247x + 141

Answers

Answer: 15,99s

when the rocket hit the ground => y = 0

=> -16x² + 247x + 141 = 0 (*)

a = - 16      b = 247     c = 141

Δ = b² - 4ac = 247² + 16.4.141 = 70033 > 0 => (*) has 2 solutions

On a roadtrip, the distance driven can be represented by
the following equation
y = 152
where x is the number of gallons of gas.
What does the 15 represent?

Answers

15 represent the car travled 15 miles / gallons.

Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion.

We have been given that -

 y = 15 * x

Where y = the distance and

x = the number of gallons of gas to cover that distance.

A common unit of capacity in English-speaking countries, equal to four quarts, the U.S. standard gallon being equal to 231 cubic inches (3.7853 liters), and the British imperial gallon to 277.42 cubic inches (4.546 liters).

Consider the units:

y[miles] = 15[??] * x[gallons]

15[??] = y[miles] / x[gallons]

[??] = [miles] / [gallons]

So the units of the parameter 15 must be [miles / gallon] to convert the gallons to miles.

Therefore 15  represents the miles / gallon for the vehicle.

A. -2 ≤ x ≤ 5

B. x ≤ -2 OR x ≥ 5

C. x ≤ -15 OR x ≥ 12

D. x ≥ 5

Thank you!

Answers

Answer:

B

Step-by-step explanation:

We have the compound inequality:

[tex]5x+7\leq-3 \text{ or } 3x-4\geq 11[/tex]

Since this is an “OR” inequality, we can solve each inequality individually. So:

1)

We have:

[tex]5x+7\leq-3[/tex]

Subtract 7 from both sides:

[tex]5x\leq -10[/tex]

Divide both sides by 5:

[tex]x\leq-2[/tex]

So, the first solution is above.

2)

We have:

[tex]3x-4\geq 11[/tex]

Add 4 to both sides:

[tex]3x\geq15[/tex]

Divide both side by 3:

[tex]x\geq5[/tex]

Our second solution is above.

Therefore, our solution is:

[tex]x\leq -2 \text{ or } x\geq5[/tex]

Since our original inequality is “OR,” our solution set remains an “OR.”

Hence, our answer is B.

Determine the domain and the range for this relationship.

Answers

Answer:

Domain: [tex]0\leq x\leq 6[/tex]

Range: [tex]\{0, 12, 24, 36, 48, 60, 72\}[/tex]

Step-by-step explanation:

Let [tex]y[/tex] or [tex]f(x)[/tex] be equal to the amount of plant food that remains after each day.

[tex]x[/tex] be the number of days that have passed.

Total amount of plant food used is 72 mm.

Number of days the experiment goes on is 6 days.

Plant food used each day is [tex]\dfrac{72}{6}=12\ \text{mm}[/tex].

So, the function will be

[tex]y=f(x)=72-12x[/tex]

[tex]x=0,y=72[/tex]

[tex]x=1,y=72-12\times 1=60[/tex]

[tex]x=2,y=72-12\times 2=48[/tex]

[tex]x=3,72-12\times 3=36[/tex]

[tex]x=4,72-12\times 4=24[/tex]

[tex]x=5,72-12\times 5=12[/tex]

[tex]x=6,72-12\times 6=0[/tex]

Value of [tex]x[/tex] is the domain which is [tex]0\leq x\leq 6[/tex].

If -2x+4= 8, will x be positive or negative? Without solving the equation, explain how you know.


Answers

Answer:

x is negative

Step-by-step explanation:

I know x will be negative without solving the equation because we can see that both sides equal positive 8 and for -2x to be positive the x value must be negative. when two negative values are multiplied they change into positive. If the x value was Positive this equation would be false.

Hope this helps you

Answer:

Yes, x will be negative.

We are given:

-2x + 4 = 8

This means that "something", in this case -2x, added to 4, equals 8

The only thing that can add to 4 and equal 8 is 4.

So, that means -2x has to equal 4, which is a positive number.

Negative x negative = positive.

-2 is already a negative number, so x has to be a negative number.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

-31 + 12s < 3s + 15
12s - 3s < 15 + 31
9s < 46
