Answer:
4y
Step-by-step explanation:
When you subtract an already negative number then the two "minus signs" will become one addition sign and it just becomes y + 3y which is 4y
(Just for example: x- (-8x) would turn into x + 8x and the answer would be 9x)
A store buys an item for $94. The store then prices the item to sell to customers. What is the selling price (in dollars) the store sells the item to customers for after applying a 62% markup? If necessary, round the answer to the closest hundredth.
Answer:
$152.28
Step-by-step explanation:
In order to determine the markup, multiply the original price by 62%
94 x 62% = 94 x .62 = 58.28
In order to determine the sale price, add the markup to the original price.
94 + 58.28 = $152.28

On a softball field, home plate is 43 feet from the pitcher’s mound. A ball is hit at an angle of 27° east of the pitcher’s mound. The ball travels 162 feet before it is caught by an outfielder.
A triangle is drawn on a baseball field. A point is at home plate, another point is at the pitcher apostrophe s mound, and another point is at an outfielder. The distance from home plate to the pitcher is 43 feet. The distance from home plate to the outfielder is 162 feet. The angle between the 2 sides is 27 degrees.
Law of cosines:
How far must the outfielder throw the ball to return it to the pitcher? Round to the nearest foot.
112 feet
125 feet
145 feet
156 feet
Answer: The answer is 125ft
Step-by-step explanation: I just did it
The law of cosines formula gives the square of the distance the
outfielder must throw the ball.
Correct response:
The distance the outfielder must throw the ball to return it to the pitcher is approximately 125 feet.How to use the cosine rule to find the distanceDistance of the home plate from the pitcher's mound = 43 feet
Angle at which the ball is hit = 27° east of the pitcher's mound
Distance the ball travels before it is caught = 162 feet
The sides, b and c, and the included angle, A, of the triangle drawn are respectively;
b = 43 feet
c = 162 feet
A = 27°
The length of the third side, a of the triangle is the distance from the outfielder to the pitcher.
According to law of cosines, we have;
a² = b² + c² - 2·b·c·cos(A)
a² = 43² + 162² - 2 × 43 × 162 × cos(27°) ≈ 15679.497105
Approximating to the nearest foot, we get;
a ≈ 125 feet
The distance the outfielder must throw the ball to return it to the pitcher is a ≈ 125 feet.Learn more about the law of cosines here:

A 4-meter ladder is placed against a wall so
that it reaches a height of 3.7m. To the nearest
tenth of a meter, how far away from the base
of the wall are the feet of the ladder?
Answer:
1.5 meters.
Step-by-step explanation:
The ladder is 4 meters.
It reaches the height of 3.7 meters on a wall.
This creates a right angled triangle of hypotenuse (4 meters) and height (3.7 meters).
We are to find the base length.
Applying the Pythagorean theorem;
a² + b² = c² , where a is the base length, b is the height length and c is the hypotenuse length.
∴ a² = c² - b² = 4² - 3.7² = 2.31
a (base length) = [tex]\sqrt{2.31}[/tex] = 1.519868415 meters
To round off the answer to the nearest tenth of a meter;
Tenth of a meter = [tex]\frac{1}{10}[/tex] × 1 meter = 0.1 meters
So we're rounding off the answer to one decimal place.
I.e 1.519868415 meters = 1.5 meters (rounded off to the nearest tenth of a meter.

Solve for x.
ax + b = r
Answer:
x=r-b/a
Step-by-step explanation:
ax=r-b
x=r-b/a
Answer:
x = r - b/a
Step-by-step explanation:
ax + b = r (Given)
ax = r - b (Subtract b on both sides)
x = r - b/a (Divide a on both sides)
You've analyzed each game. Which game earns

A.game 1 (200 points per hit)
B. Game 2 (points double on each hit)
C. It depends
Answer:
C, For up to 11 hits, Game 1 gives the player higher scores. But for 12 or more hits, Game 2 does. That's because exponential growth eventually exceeds linear growth.

у = ?
*please explain to me, step by step, how you got the answer, too, so I can understand.
Answer:
y = 18
Step-by-step explanation:
3.23(y – 18) - 19.17 = -19.17
3.23y - 18 x 3.23 = -19.17 + 19.17
3.23y - 58.14 = 0
3.23y = 58.14

Answer:
12.25
Step-by-step explanation:
The angle bisector divides the triangle sides proportionally, so we have ...
x/3.5 = 7/2
x = 3.5×7/2 . . . . multiply by the denominator
x = 12.25

Additional comment
The proportion can be written 4 ways. I find it convenient to write it with the unknown value in the numerator. That way, the solution is found in one step: multiply by the denominator.
Given the function f (x) = x² + 5, evaluate f (-10)
Answer:
f(-10)=105
Step-by-step explanation:
When something says f(x), the (x) is your plugin value. So basically in this scenario, x= -10
1) f(-10)= (-10)^2+5
2)f(-10)= 100+5
3) f(-10)= 100+5
Ok hopefully I remembered my properties of exponents correctly, but I'm pretty sure that's the answer. If it isn't, you should try making the 100 negative instead of positive from step 2 and work from there.

Caleb found the product of all factors, not just the ones common to each term. Then the correct option is C.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The expression is given below.
⇒ 3x² – 9x
The factor of 3x² will be 3 · x · x.
The factor of 9x will be 3 · 3 · x.

There is a number such that 7 times the number minus 15 is equal to 41
Answer: 6.571
Step-by-step explanation: If you want the exact answer, it’s 6.57142857
Answer:
8 is the number
Step-by-step explanation:
So in order to find out the "number" we are going to have to turn the equation around. First of all the equation says "minus 15 is equal to 41" so we are going to add 15 to 41:
41 + 15 = 56
So now we are going to divide 7 from 56 because we are doing the equation backwards:
56/7 = 8
So now we check our work by replacing the number in the sentence with eight, "7 times 8 minus 15 is equal to 41" which would make the equation look like this:
7 * 8 + 15 = 41
First we multiply 7 by 8:
7 * 8 = 56
Now we subtract 15 from 56:
56 - 15 = 41
Making the equation look like this:
41 = 41

Coach leonardo used 9 1/2 meters of string to mark a soccer field for a game. He also used 2 2/5 meters of string to mark a spot where coaches and players will be standing during the game. Which expression could be used to determine the amount of string in meters, coach lenore i used altogether
Answer:
10 19/10 meters
Step-by-step explanation:
Step one:
given data
let the amount of string used for the soccer field be x
and the amount used for coach spot be y
Also, let the total string used be represented as T
Step two:
Hence the expression for the total is
T= x+y
T= 9 1/2+ 2 2/5
T= 9.5+ 2.4
T= 11.9
or
T= 119/10 meters
or
T= 10 19/10 meters
