Who started the problem correctly? The problem form is (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
Answer:
Shane started the problem correctly
Step-by-step explanation:
We are given problem (-5) - (-1 3/4).
Mariah started the problem as (-5) + 1 - 3/4
Shane started the problem as (-5) + 1 + 3/4
We need to find who started the problem correctly.
The problem should be started by converting the mixed fraction into improper fraction i,e
[tex]-5-(-1\frac{3}{4})\\=-5-(-1-\frac{3}{4} )\\=-5-(-\frac{7}{4})[/tex]
Now we will solve bracket by multiplying -1 with term inside the bracket i.e
[tex]=-5+\frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Let's compare both the procedures now:
Mariah:
[tex](-5) + 1 - \frac{3}{4}[/tex]
[tex]=(-5) - \frac{1}{4}[/tex]
[tex]=\frac{-21}{4}[/tex]
Therefore, Mariah did not start the problem correctly.
Shane:
[tex](-5) + 1 + \frac{3}{4}[/tex]
[tex]= -5 + \frac{7}{4}[/tex]
[tex]= \frac{-13}{4}[/tex]
Therefore, Shane started the problem correctly.

what is the sell tax of 8.00 dollars
Answer:
A tax of 7.5 percent was added to the product to make it equal to 8.6. So, divide 7.5 by 100 to get 0.075. Divide the final amount by the value above to find the original amount before the tax was added. In this example: 8.6 / 1.075 = 8.

In 2010, the population of China was around 1.400,000,000 and growing
at a rate of 1.65% per year. What should the population be this year?*
Answer:
1423100000
Step-by-step explanation:
1.65% of 1.4 billion is 23,100,000. Knowing this you just add the two numbers together to find what an extra 1.65% of people being added to the population would result in.
The current population of China is 1,423,100,000 using the compound rate of increment method.
What is a compound rate of increment?The compound rate of increment is a type of increment that is compounded after time period it is said to be compounded. After that particular period, the increment is calculated and then added with the primary number. For the next duration, the increment is calculated on the sum.
Given, the total of population of China in 2010 was (P) = 1,400,000,000.
The rate of increase of population is (r) = 1.65%
Duration (n) = (2022 - 2010) years = 12 years.
Therefore, the total of population of China in 2022 (S)
= P(1 + r)ⁿ
= 1,400,000,000(1 + 1.65/100)¹²
= 1,400,000,000(1 + 0.0165)¹²
= 1,400,000,000(1.0165)¹²
= 1,423,100,000
Therefore, the population of China in 2022 is 1,423,100,000.

I don’t know if I am supposed to substitute the x variable in f(x) or leave the f(x) the same.

f(0) = [tex]\sqrt{100-0}[/tex]

Solving Multi-Step Equations Using the Distributive Property
Answer:
w=6
Step-by-step explanation:
−5(w−5)=−5
= divide both sides by -5
=w-5=1
add 5 to both sides
= w=6
Answer:
w=6
Step-by-step explanation:
5(w−5)=−5
(−5)(w)+(−5)(−5)=−5(Distribute)
−5w+25=−5
Step 2: Subtract 25 from both sides.
−5w+25−25=−5−25
−5w=−30
Step 3: Divide both sides by -5.
−5w−5=−30−5
w=6

The probability that the selected student is a sophomore given that he is a boy will be 5/12.
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
we need to select the probability that the selected student is a sophomore given that he is a boy;
In this case;
P(B) = P(boy)
P(A) = P(sophomore)
The total number of students which is 12 + 18 = 30
From the table;
P(B) = 12/30
P(A n B) = 5/30
So;
P(A|B) = 5/30 / 12/30
= 5/30 x 30/12 = 5/12
Hence, the probability that the selected student is a sophomore given that he is a boy will be 5/12.

Evelyn is buying a motorcycle that costs $14,000. The tax rate is 6.75%, and she plans to make a down payment of $1,500. The sales tax is
added before the down payment is applied. She is considering a three-year loan
Answer:
449.10
Step-by-step explanation:
Her monthly payment, if she is considering a three-year loan is $373.47
Given the cost of the motorcycle to be $14000
If the tax rate is 6.75%, the total cost plus tax is expressed as:
Final cost = 14000+(0.0675 * 14000)
Cost of motorcycle = 14000 + 945
Cost of motorcycle = $14945
If she plans to make a down payment of $1,500 before the sales tax is applied, then;
Balance = 14945 - 1500
Balance = $13,445
If she considers a three-year loan, her monthly payment will be ;
Monthly payment = 13,445/36
Monthly payment = $373.47
Hence her monthly payment if she is considering a three-year loan is $373.47

Answer: A
Step-by-step explanation:
3x² - 10x + 5 = 0
a = 3 b = -10 c = 5
Δ = b²- 4ac = 100 - 4.3.5 = 40 > 0 => have 2 solutions
=> x = [tex]\frac{10+\sqrt{40} }{6}[/tex] or x = [tex]\frac{10-\sqrt{40} }{6}[/tex]
[tex]x= \frac{10\pm \sqrt{40} }{6}[/tex] is the solution to the given quadratic equation.
What is quadratic equation?
Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = [tex]ax^{2} +bx+c[/tex] = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
Given quadratic equation
[tex]3x^{2} -10x+5=0[/tex]
a = 3, b = -10, c = 5
Quadratic formula = [tex]\frac{-b\pm \sqrt{b^{2} -4ac} }{2a}[/tex]
[tex]x= \frac{-(-10)\pm \sqrt{(-10)^{2} -4(3)(5)} }{2\times3}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{100 -60} }{6}[/tex]
⇒ [tex]x= \frac{10\pm \sqrt{40} }{6}[/tex]

Answer:
3, 4, 5
