Answer:
$1800
Step-by-step explanation:
If we pay $25 monthly, then at the beginning of the seventh month you should have paid:
$25*6 = $150
At the beginning of the seventh month we will have:
$1950 - $150 = $1800.
No interested is charged during the introductory period, so at the beginning of the seventh month the balance will be $1800.

If the graph of y= |x| is translated so that the point (1, 1) is moved to (4,1), what is the equation of the new graph?
Answer:
The new equation is y= (x-3)
Step-by-step explanation: we know that the point (1, 1) is moved to (4,1).
So, the rule of the translation is: [tex](x,y) -----> (x+3, y)[/tex]
that means the translation is 3 units to the right
Answer:
[tex]y=|x-3|[/tex]
Step-by-step explanation:
The parent absolute function is
[tex]y=|x|[/tex]
The graph of y= |x| is translated so that the point (1, 1) is moved to (4,1). It means the rule of translation is
[tex](x,y)\rightarrow (x+3,y)[/tex]
it means the graph of y=|x| translated 3 units right. So, the new vertex of the function is (3,0).
The vertex form of an absolute function is
[tex]y=|x-h|+k[/tex]
The new vertex of the function is (3,0). Substitute h=3 and k=0 in the above equation.
[tex]y=|x-3|+0[/tex]
[tex]y=|x-3|[/tex]
Therefore, the required equation is y=|x-3|.

A rectangle's length and width are in a ratio of 5:2. The area is 160 square centimeters. What are the length and width?
If you could solve this please do so asap
Answer: The length and width are 20 square centimeters and 8 square centimeters
Explain: 20:8 can be reduced to 5:2 as a ratio. 20 times 8 equals 160.
Answer:
length = 20 cm and width = 8 cmStep-by-step explanation:
l - length
w - width
length and width are in a ratio of 5:2
[tex]\dfrac{l}{w}=\dfrac{5}{2}[/tex] cross multiply
[tex]2l=5w[/tex] divide both sides by 2
[tex]l=\dfrac{5w}{2}[/tex]
the area is 160cm²
[tex]lw=160[/tex]
We have the system of equations:
[tex]\left\{\begin{array}{ccc}l=\dfrac{5w}{2}&(1)\\lw=160&(2)\end{array}\right[/tex]
Substitute (1) to (2):
[tex]\left(\dfrac{5w}{2}\right)(w)=160\\\\\dfrac{5w^2}{2}=160\qquad\text{multiply both sides by 2}\\\\5w^2=320\qquad\text{divide both sides by 5}\\\\w^2=64\to w=\sqrt{64}\\\\w=8[/tex]
Put the value of w to (1):

Divide 4200 by a multiple of 10 so that the quotient is also a multiple of 10
Answer:
4200 divided by 10
Step-by-step explanation:
To make 4200 a multiple of ten after dividing it by a multiple of ten, we first find the number of 5's in 4200 to see how many 10's go into 4200. Since 4200 = 6*7*2*2*5*5, we see that there are 2 fives. This means that there are two tens too. Since we have to keep 4200 a multiple of ten after dividing it by another 10. So the only possible way to do that is dividing 4200 by 10.
Dividing 4200 by the power of 10, 100, results in the quotient 42, which is also a multiple of 10. This is achieved by moving the decimal point two places to the left in the number 4200 due to the two zeros in the power of 10.
Explanation:In this mathematics problem, you are asked to divide 4200 by a multiple of 10 such that the result, or quotient, is also a multiple of 10. The key to this problem lies in understanding the concept of dividing by powers of 10.
When you divide a number by a power of 10, you move the decimal point to the left by as many places as there are zeros in the power of 10. So if you wanted to divide 4200 by a multiple of 10 so that the result is also a multiple of 10, you might choose 100 (10^2) as your divisor. Why? Because there are two zeros in the power of 10, which means you move the decimal point two places to the left in the number 4200.
So when you divide 4200 by 100, you get 42 which is a multiple of 10. Therefore, 4200 divided by a multiple of 10 (100 in this case) gives a quotient (42) that is also a multiple of 10.

Replace x with 3 and solve for Y.
If y equals 8 in both equations, then it is a solution.
y = -5(3) +1 = -15+1 = -14
-14 does not equal 8 , so it is not a solution.
No because -5• 3 +1 does not equal 8 makings it impossible for it to work for that equation. Then 3•3-2 doesn’t equal 8 either so (3,8) is not a solution for these equations
In the United States, birth weights of newborn babies are approximately normally distributed with a mean of μ = 3,500 g and a standard deviation of σ = 500 g.
What percent of babies born in the United States are classified as having a low birth weight (< 2,500 g)? Explain how you got your answer.
answer:The z-score for 2,500 g is –2.
According to the empirical rule, 95% of babies have a birth weight of between 2,500 g and 4,500 g.
5% of babies have a birth weight of less than 2,500 g or greater than 4,500 g.
Normal distributions are symmetric, so 2.5% of babies weigh less than 2,500g.

Gayle and Jerry had some money. After their mother gave each of them $20, Gayle had twice as much money as Jerry and Jerry had $50 less than Gayle. How much money did Gayle have at first?
Answer:
$100
Step-by-step explanation:
To find out how much money Gayle initially had, we solved the two equations provided by the problem: G + 20 = 2(J + 20) and J + 20 = G + 20 - 50. Solving these equations, it was found that Gayle initially had $90.
Explanation:The question is asking us to figure out how much money Gayle had before their mother gave them each $20. Let's denote the amount of money Jerry initially had as J and the amount of money Gayle initially had as G. According to the problem, after the mother gave them $20 each, Gayle had twice the amount of Jerry's, which mathematically translates to G + 20 = 2(J + 20). Likewise, Jerry had $50 less than Gayle, which can be written as J + 20 = G + 20 - 50. Thus we are given a system of two equations that we can solve simultaneously.
Both equations can be simplified to G = 2J + 20 and J = G - 50. By substituting J = G - 50 in the first equation, we can solve for G to get G = 2(G - 50) + 20 which further simplifies to G = $90. Thus, Gayle initially had $90.

Write the number 7 ones 9 tens 9 hundreds
Answer:
997
From right to left, the place values are, ones, tens, hundreds, thousands, etc.
The number with '7 ones', '9 tens', and '9 hundreds' is written as 997 in numeral form, by combining the values of each digit based on their place value.
When writing the number that consists of '7 ones', '9 tens', and '9 hundreds', we are dealing with a three-digit number where each place value represents a power of 10. To construct the number, we consider the value each digit represents:
The '9 hundreds' means 9 × 100 (which is 900).
The '9 tens' means 9 × 10 (which is 90).
The '7 ones' means 7 × 1 (which is 7).
Adding these values together, we have 900 (hundreds) + 90 (tens) + 7 (ones), which equals 997. This is the decimal representation of the number expressed by the student.
Therefore, the number 7 ones 9 tens 9 hundreds written in numeral form is 997.
