Answer:
283
First, multiply 15 and 18. You get 270. Then divide 12 and 3. You get 4. Add 270, 4, and 9 together to get 283

You have $138 in a savings account and save $12 per week. Your friend has $98 in a savings account and saves $17 per week. How many weeks will it take for you and your friend to have the same balance?
Solution
Provided :-
• I have $138
• I save $12 per week
• Friend have $ 98
• He saves $17 per week
Let the number of weeks required to have same balance be x
→ 138 + 12x = 98 + 17x
→ 138 - 98 = 17x - 12x
→ 40 = 5x
→ x = 8
So we need 8 weeks
Answer: 8 weeks
Step-by-step explanation:
Let x = the number of weeks
138+12x=98+17x
40+12x=17x
40=5x
x=8

3.48 gallons of milk is sold for $10.16. If you want to buy 10.83 gallons of milk, how
much will you have to pay?
Answer:
$31.62
Step-by-step explanation:
Assuming the price is proportional to the volume, your price will be ...
price/(10.83 gal) = ($10.16)/(3.48 gal)
price = $10.16(10.83/3.48) ≈ $31.62
You will have to pay $31.62.
Can anyone help?i been going at this for a while and i still cant figure it out, i dont really understand how to even get the answer id appreciate some help :D
Answer:
A) 44.26
B) 9.43
C) (2.5,3.5)
D) OH
E) 26.26
Step-by-step explanation:
Let’s figure out the lengths first. Three are straight line, so are easy:
HE=9, SE=11, SU=9
The other two, you need to use the distance formula or Pythagorean Theorem. OH=8²+5²=c² = 64+25=c² = 89=c² = √89 = 9.43
OU=3²+5²=c² = 9+25=c² = 34=c² = √34 = 5.83
Now we can start answering the questions.
A) 9+11+9+9.43+5.83=44.26
B) 9.43
C) You already have: (2.5,3.5)
D) OH=9.43. EH=9. OH is longer.
E) HU is 11. OH is 9.43. OU is 5.83. 11+9.43+5.83=26.26

If F is the midpoint of DE, DF = 3x+5 and FE = 5x-19 , Find DF
Answer:
41
Step-by-step explanation:
when there is midpoint it bisects the segment(cuts it in equal halfs)
3x+5 = 5x-19
3x + 24 = 5x
24 = 2x
12 = x
3(12) + 5 =
36 + 5
41
Answer:
The value of segment DF is 41 units.
Step-by-step explanation:
If we know that F is the midpoint of DE, we can conclude that DF and FE have the same value. This lets us set up the following equation:
DF = FE, which when we substitute in our given values is:
3x + 5 = 5x - 19
The next step is to solve this equation. We should start by subtracting 3x from both sides of the equation.
5 = 2x - 19
Then, we can add 19 to both sides of the equation.
24 = 2x
Finally, we can divide both sides by 2.
x = 12
Now that we have a value for x, we need to find the length of DF. To do this, we can just plug in our value for x into the given expression for DF and simplify.
DF = 3x + 5 = 3(12) + 5 = 36 + 5 = 41
Therefore, the correct answer is 41.
Hope this helps!
Simplify the following algebraic expression:
- 2(x - 1) + 3(6x – 7)
Answer:
16x-19
Step-by-step explanation:
Step-by-step explanation:
Hey, there!
While simplifying the algebraic expression you must remember: multiply or take LCM first and then add or or subtract like terms then if there is division then you may cut like terms of numerator and denominator.
Here,
[tex] - 2(x - 1) + 3(6x - 7)[/tex]
Is given.
Multiply (x,-1) by -2 and (6x,-7) by 3.
[tex] (- 2x + 2) + (18x - 21)[/tex]
open brackets.
[tex] = - 2x + 2 + 18x - 21[/tex]
Add and subtract like terms.
[tex] = - 2x + 18x + 2 - 21[/tex]
[tex] = 16x - 19[/tex]
Therefore, the answer is (16x - 19).

11. Avery and Bradley work at a large electronics manufacturer that produces DVD players. The
defective rate on the assembly line has gone up to 12% and the manager wants to know the
probability that a skid of 50 DVD players will contain at least 3 defective units.
a) Help Avery use the binomial distribution P(x)=, C.pqrs to answer this question
Answer:
0.9487
Step-by-step explanation:
a) The probability of having a defective product = p = 12% = 0.12
The probability of not having a defective product = q = 1 - p = 1 - 0.12 = 0.88
The number of DVD players = n = 50
X is the number of defective products.
The probability that a skid of 50 DVD players will contain at least 3 defective units = P(X ≥ 3) = 1 - P(X ≤ 2)
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)
Using binomial:
P(X = 0) = [tex]C(n,x)p^xq^{n-x}=C(50,0)p^0q^{50-0}=\frac{50!}{(50-0)!0!}*0.12^0*0.88^{50-0}=0.0017[/tex]
P(X = 1) = [tex]C(n,x)p^xq^{n-x}=C(50,1)p^1q^{50-1}=\frac{50!}{(50-1)!1!}*0.12^1*0.88^{50-1}=0.0114[/tex]
P(X = 2) = [tex]C(n,x)p^xq^{n-x}=C(50,2)p^2q^{50-2}=\frac{50!}{(50-2)!2!}*0.12^2*0.88^{50-2}=0.0382[/tex]
P(X ≤ 2)= 0.0017 + 0.0114 + 0.0382 = 0.0513
P(X ≥ 3) = 1 - P(X ≤ 2) = 1 - 0.0513 = 0.9487 = 94.87%

What type of number is 37.9?
A. Real
B . Imaginary
C. Complex
Answer:
A. Real number
Step-by-step explanation:
Fact :Real numbers that include decimal points are known as floating point numbers because the decimal floats within the numbers.
The number 37.9 is a real number which is the correct option (A).
What are real numbers?Real numbers are defined as the value of a continuous quantity that can represent a distance along a line a real number in mathematics. Rational and irrational numbers are both real numbers. Rational numbers such as integers (-7, 0, 4), fractions(5/2,7/2, 4.2), and irrational numbers such as √5, π, etc., are all real numbers.
What is a complex number?A complex number is a combination of real values and imaginary values. It is denoted by z = a + ib, where a, and b are real numbers and i is an imaginary number.
Given that number is 37.9
Due to the fact that decimal places can move about within real numbers containing decimal points, these numbers are referred to as floating point numbers.
Hence, the number 37.9 is a real number.

The Roe family of four showers once a day with an average of 10 minutes per shower. The shower has a flow rate of 5 gallons per minute. How many gallons of water does the family use in one year?
4 people x 10 minutes each = 40 minutes per day.
5 gallons per minute x 40 minutes = 200 gallons per day.
200 gallons per day x 365 days per year = 73,000 gallons a year.

The coordinates of the midpoint of GH¯¯¯¯¯¯¯¯are M(−132,−6) and the coordinates of one endpoint are G(−4, 1).
Answer: (-260, -13)
Step-by-step explanation:
To find the midpoint of a line we find the average of x coordinates and the average of the y coordinates.So since two of the endpoint is already given we could find the midpoint by setting and equation up.
[tex]\frac{-x+(-4)}{2} = -132 x= -260[/tex]
The same way for the y coordinates
[tex]\frac{y+(1)}{2} = -6[/tex] y = -13
Find the number by which 4732 should be divided to get perfect square.
Answer:
The required number is 7.
Dividing by this gives the perfect square 676.
Step-by-step explanation:
Finding the prime factors:
2) 4732
2) 2366
7) 1183
13)169
13
So 4372
= 2^2 * 7 * 13^2
= 4 *169 * 7
= 676 * 7
Now 676 is a perfect square so the answer is 7.
= 1283 * 4.
Answer is 1283.
If f(x) = 1/9x - 2, what is f^-1 (x)
Greetings from Brasil...
For reverse function, just invert the X by the Y and vice versa.
Note that F(X) = Y and F⁻¹(X) = Y⁻¹
F(X) = 1(9X - 2) ⇔ Y = 1(9X - 2)
replacing X with Y⁻¹
X = 1(9Y⁻¹ - 2)
Y⁻¹ = (2X + 1)/9XWhy can’t you use the product of powers rule to simplify this expression? Explain. 34 · 28
Sample Answer: To use the product of powers rule, the powers must have the same base. In this expression, the bases are 3 and 2, which are different, so the rule does not apply.
Answer:
To apply the product of powers rule, the bases must be the same.
In this example, the bases are 2 and 3, so they are not the same.

solve the equations for all values of x by completing the square x^2+62=-16x
Answer:
[tex]x = \sqrt{2} - 8\\x = -\sqrt{2} - 8[/tex]
Step-by-step explanation:
To complete the square, we first have to get our equation into [tex]ax^2 + bx = c[/tex] form.
First we add 16x to both sides:
[tex]x^2 + 16x + 62 = 0[/tex]
And now we subtract 62 from both sides.
[tex]x^2 + 16x = -62[/tex]
We now have to add [tex](\frac{b}{2})^2[/tex] to both sides of the equation. b is 16, so this value becomes [tex](16\div2)^2 = 8^2 = 64[/tex].
[tex]x^2 + 16x + 64 = -62+64[/tex]
We can now write the left side of the equation as a perfect square. We know that x+8 will be the solution because [tex]8\cdot8=64[/tex] and [tex]8+8=16[/tex].
[tex](x+8)^2 = -62 + 64[/tex]
We can now take the square root of both sides.
[tex]x+8 = \sqrt{-62+64}\\\\ x+8 = \pm \sqrt{2}[/tex]
We can now isolate x on one side by subtracting 8 from both sides.
[tex]x = \pm\sqrt{2} - 8[/tex]
So our solutions are
[tex]x = \sqrt{2} - 8\\x = -\sqrt{2} - 8[/tex]

Stanley drives her scooter 6 kilometres South. He stops for lunch and then drives 3 kilometres east. What distance did he cover? What was his displacement?
Answer:
a) What distance did he cover?
9 km
b) What was his displacement?
6.71kmSE
Step-by-step explanation:
a) What distance did he cover?
Total distance covered = 6km south + 3km east = 9km
b) What was his displacement?
Displacement =√( 6km)² + (3km)²
=√ 36 + 9
= √45
= 6.7082039325kmSE(SouthEast)
Approximately = 6.71kmSE
