Answer:

Ricky had 1201 hits and

Pedro hade 1481 hits

Step-by-step explanation:

Let Ricky be 'y'.

Since, Pedro hit 280 mroe than Ricky.

Pedro is 'y+ 280'

Thus,

y + y+ 280 = 2682

2y = 2402

y = 1201

Ricky had 1201 hits and

Pedro hade 1201 + 280 = 1481 hits

Step-by-step explanation:

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

__

  (4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

  11x -7 = 180 . . . . . . . divide by °, collect terms

  11x = 187 . . . . . . . . add 7

Answer:

P(Not a 3)=0.85. This is option C.

Step-by-step explanation:

P(Not a 3) would include values 1,2 and 4.

Therefore, P(Not a 3) would be the combined totals of the probabilities of P(1), P(2) and P(4).

P(Not a 3)= P(1)+P(2)+P(4)

P(Not a 3)= 0.30+0.40+0.15

P(Not a 3)=0.85

Alternate method

P(Not a 3) is the same as 1-P(3)

P(Not a 3)=1-P(3)

P(Not a 3)= 1-0.15

P(Not a 3)=0.85

what percent of 7 is 3.5

3.5 is half of 7, so 100%: 2 = 50%

Answer: 50%

I have shown two methods, both work well and can be used to solve other scenarios as well.

[Method One]

     We will set up a proportion and solve.

-> A percent divided by 100 is a decimal. This means 100% = 1 in our proportion

[tex]\frac{1}{7} =\frac{x}{3.5}[/tex]

7x = 3.5

x = 0.5

0.5 * 100 = 50%

[Method Two]  

     We will put the whole value in the denominator, and the "what percent of" value is the numerator.

[tex]\displaystyle \frac{3.5}{7}[/tex]

0.5

0.5 * 100 = 50%

Answer:

A = $14,745.544

Step-by-step explanation:

The equation for compound interest is 

A = P (1+i)t 

A = final value

P = amount invested (principal) (10000)

i = interest rate, expressed as a decimal (.05)

t = number of years invested (8)

This formula assumes annual compounding.

Plugging in what we know.

A = 10000(1.05)^8

A = 10000 (1.47745544)

A = $14,745.544

A) the price of the bag without discount was $120, and B) the discount on the wallet was 45%.

Answer:

The number of walnut pounds we need to add is 10

Step-by-step explanation:

We need to make a mixture that costs $1 per pound.

That means that the total cost of our mixture, divided by the number of pounds must be equal to 1.

[tex]\frac{MixtureCost}{NumberOfPounds} = 1[/tex]

Well, we know that the total cost of our mixture is equal to the cost of the cashews + cost of walnuts.

[tex]MixtureCost = CashewsCost + WalnutsCost[/tex]

We also know that we'll buy 8 pounds of cashews that cost $1.25 each and some amount of pounds (which we'll call x) of walnuts that cost $0.80.

Knowing all of that, we can write this:

[tex]MixtureCost=8*1.25 + x*0.8[/tex]

If we make that multiplication, we have that

[tex]MixtureCost=10+x*0.8[/tex]

Now that we know the cost of our mixture, we just need to know the total number of pounds... But we already know that, don't we?

We know that there are 8 pounds of cashews and x pounds of walnuts, so here's what we can write:

[tex]NumberOfPounds=8+x[/tex]

Now, if we plug in the values we found in the first equation, here's what we have:

[tex]\frac{10+x*0.8}{8+x}=1[/tex]

The 8+x is dividing, so i'll pass it to the other side multiplying:

       [tex]10+0.8*x=x+8[/tex]

The 10 in the left side will go to the right side with a negative sign:

[tex]0.8x=x-2[/tex]

Now, if I pass the x from the right side to the left one changing signs:

[tex]0.8x-x=-2\\\\-0.2x=-2[/tex]

By changing signs from both sides, we have that:

[tex]0.2x = 2\\\\x = 10[/tex]

Therefore, the number of walnut pounds we need to add is 10

[tex]\text{Given that,}~ (2x+5, 7)=(7,y)\\\\\text{So,}~ y = 7 ~ \text{and}~2x +5 = 7\\\\~~~~~~~~2x+ 5=7 \\\\\implies 2x = 7- 5 \\\\\implies 2x = 2\\\\\implies x = \dfrac 22 \\\\\implies x = 1\\\\\text{Hence,}~~ x = 1 ~ \text{and}~ y = 7[/tex]

Step-by-step explanation:

[tex] {x}^{2} + 2x - 2 = 0[/tex]

Now Adding three on both sides we get

[tex]{x}^{2} + 2x - 2 + 3 = 0 + 3[/tex]

[tex] {x}^{2} + 2x + 1 = 3[/tex]

[tex] {(x + 1)}^{2} = 3[/tex]

Answer:

5 days

Step-by-step explanation:

This problem is an inverse proportion case. Having two variables: number of workers and time (in days); when we increase the number of workers, the time needed decreases; vice versa. Therefore, we can use the multiplication method: (workers * time) will always stay constant.

Let's say the time (in days) needed by the eleven workers is t,

5*20 = (3*10) + (14*t)

100 = 30+14t

70 = 14t

5 = t

It will take the eleven-workers 5 more days to finish the road.

Step-by-step explanation:

The Circumference of a circle can be displayed by this formula:

[tex]C = 2\pi r[/tex]

[tex]C[/tex] is the circumference, and [tex]r[/tex] is the radius.

So just plug in 31 for [tex]C[/tex], and simplify:

[tex]31 = 2\pi r[/tex]

Because the question is asking for the diameter, we only need to divide both sides by pi, as [tex]2r[/tex] is the same thing as diameter.

[tex]9.87 = 2r[/tex] (rounded to the nearest hundredth)

We can even rewrite [tex]2r[/tex] as [tex]d[/tex], which stands for diameter, to make things a little simpler.

[tex]9.87 = d[/tex]

Now we just take 9.87, and round it to the nearest whole number, and we get 10. So your answer is 10 Inches.

Hope it helps, have a fantastic day.
