How would you solve this problem? (Worth 10 points, pls help!)

Answers

Answer:

(22,0)

Step-by-step explanation:

1. Select any two points given and find their slope (rise/run)

       (-38, 40) and (-23, 30)

      slope =   [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3

2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.

    y = mx + b ⇒ 40 = -2/3 (-38) + b

3. Solve for b

   40 = -2/3 (-38) + b

   40 = 76/3 + b

   40 - 76/3 = b

   b = 44/3

4. To find the x-intercept, set y = 0, and solve.

   y = -2/3 x + 44/3

   0 = -2/3 x + 44/3

   2/3 x = 44/3

   x = 22

What is the name of the tide when the sun, moon, and earth are all aligned, causing the greatest pull for highest and lowest tides?

Question 10 options:

Low tide


Spring tide


High tide


Neap tide

Answers

Answer:

Whenever the earth, moon and sun are aligned, the gravitational pull of the moon is augmented by the gravitational pull of the sun, causing larger than average tidal ranges — meaning especially high high tides and very low low tides. These extreme tides are called “spring tides.”

Step-by-step explanation:

The answer to your question is Spring tides

A fruit market equally divided 80 red apples into 8 containers, and equally divided 54 green apples into 6 containers. Natalie bought 1 container of red apples and 1 container of green apples.

Which equation could be used to find n, the total number of apples Natalie bought?


80 ÷ 6 + 54 ÷ 8 = n

80 ÷ 8 + 54 ÷ 6 = n

(80+54)÷(8+6)=n

80 × 8 + 54 × 6 = n

Answers

Answer:

The second one

Step-by-step explanation:

80 / 8 tells how many red

+ 54 / 6 tells how many green

The second one.

80 red apples into 8 containers = 80/8
54 green apples into 6 containers = 54/6

1 container of red = 80/8
1 container of green = 54/6

If I want to find the total of the apples Natalie bought I add the two containers together

So 80/8+54/6=n
n=10 red+9 green
n=19
19 apples

Pete wants to buy a new gaming controller that is on sale. The controller costs $105 and is on sale for 35% off. If the sales tax is 10.1%, how much will he pay for the controller?

The final price is: $_________

Answers

Answer:

The final Price is: $75.14

Step-by-step explanation:

you first have to do -=- which means /105=35%/100

then you would do 105x35=3675/100=36.75

then Subtract 105-36.75=68.25.

The next step is to do -=- /68.25=10.1%/100

you would multiply 68.25 and 10.1 and get 689.325 the you would divided that by 100 and get 6.89325 then you would add 68.25 and 6.89325 and get 75.14.

2(3y + 7 + 5) = 196 - 16
what’s the value of y?
And tell me how you know this and why or Y ahahahahahaha

Answers

Answer:

y=60

Step-by-step explanation:

196 - 16 = 180

7 + 5 = 12

12 + 3y = 15y

2 * 15y = 30y

180 ÷ 30 = 60

y = 60

Answer:

y=26

Step-by-step explanation:

Let's solve your equation step-by-step.

2(3y+7+5)=196-16

Step 1: Simplify both sides of the equation.

2(3y+7+5)=196-16

(2)(3y)+(2)(7)+(2)(5)=196+-16 (Distribute)

6y+14+10=196+-16

(6y)+(14+10)=(196=-16) (Combine Like Terms)

6y+24=180

Step 2: Subtract 24 from both sides.

6y+24-24=180-24

6y=156

Step 3: Divide both sides by 6.

6y/6 = 156/6

y=26

Mr .Smith goes to eat for his son's birthday. The total bill is $56.50. If Mr. Smith leaves a 22% tip. What is the tip amount? What is the total cost of the meal with tip included?

Answers

Finding the tip amount:
(56.5)(22)=1,243
1,243/100=12.43
The tip amount is $12.43.
Finding the total cost:
56.50+12.43=68.93
The total cost of the meal with tip included is $68.93.
56.50 * .22 = 12.43
56.50 + 12.43 = $68.93

(219,379.01 - x) / x = .3321

Answers

Answer:x = 164686.592598

Step-by-step explanation:

219379.01−x/x = 0.3321

−x+219379.01/x = 0.3321

Step 1: Multiply both sides by x.

−x+219379.01≈0.3321x

−x+219379.01 − 0.3321x = 0.3321x−0.3321x (Subtract 0.3321x from both sides)

−1.3321x + 219379.01 = 0

−1.3321x + 219379.01 − 219379.01 = 0 − 219379.01 (Subtract 219379.01 from both sides)

−1.3321x = −219379.01

−1.3321x/−1.3321 = −219379.01/−1.3321

(Divide both sides by -1.3321)

x = 164686.592598

Answer:

  164,686.59

Step-by-step explanation:

Carry out the division, then solve for x.

  (219,379.01 - x) / x = .3321 . . . . . given

  219,379.01/x -1 = 0.3321

  219,379.01/x = 1.3321 . . . . add 1

  219,379.01/1.3321 = x ≈ 164,686.59 . . . . multiply by x/1.3321

Rounded to 8 significant digits, the value of x is 164,686.59.
