Can someone tell me
How to solve this and a explanation?
Answer:
C
Step-by-step explanation:
Okay so on Saturday there is a 30% sale plus she comes early so +10% and that makes 40% off.
10% of 400=40
multiply by 4 to get 40%, 40*4=40%
40%=160
400-160=240
Hope this helps
400 x 0.30 = 120
400 - 120 = 280
280 x 0.10 = 28
280 - 28 = 252
So 252 is you answer.
How many solutions does the nonlinear system of equations graphed below have?

What is a graph?A graph, which is a diagrammatic depiction of a network, describes the connection between lines and points. A graph consists of various points and the separation between two of them.
It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
For example to draw the equation y = 6x +9 this will draw a straight line in the coordinate geometry.
The solution of any equation is a point of intersection of a graph as we can see that the graph which is present in the question has only one intersection so there will be only one answer.

Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8
On the day of a child’s birth, a deposit of $25,000 is made in a trust fund that pays 8.75% interest, compounded continuously. Determine the balance in this account on the child’s 25th birthday.
9514 1404 393
Answer:
$222,822.57
Step-by-step explanation:
The account balance is given by ...
A = P·e^(rt)
where P is the principal invested at interest rate r for t years.
A = $25,000×e^(0.0875·25) ≈ $222,822.57

The difference of a number 5 and 4/ 3 is 11/3.
What is subtraction of fractions?Subtracting fractions include the subtraction of two or more fractions with the same or different denominators. Like fractions can be subtracted directly but for unlike fractions we need to make the denominators same first and then subtract them.
Given that, the difference of a number and 4/ 3 is 11/3.
Let the unknown number be x.
Here, x-4/3 =11/3
x= 11/3+4/3 (Transpose 4/3 to RHS of the equation)
To add like fractions, add the numerators and keep the denominator same. That is
x= 15/3
x=5
Therefore, the unknown number is 5.

Answer:
B
Step-by-step explanation:
f(x) = 3x - 7
g(x) = 8x + 2
f(x) * g(x) = (3x - 7)(8x + 2) {Use FOIL method}
= 3x*8x + 3x *2 +(-7)*8x + (-7)*2
= 24x² + 6x - 56x - 14 {Combine like terms}

5. Write the polynomial in standard form. Then name the polynomial based on its degree and
number of terms.
5x + 2x4 – 4
O 5x – 4 + 2x4, not a polynomial
O 2x4 + 5x – 4; fourth-degree trinomial
O 5x + 2x4 – 4; quadratic monomial
O 2x4 + 5x – 4; cubic binomial
Answer:
Option (2)
Step-by-step explanation:
Standard form of the polynomial will be in the form of (ax⁴+ bx³+ cx²+ dx + e).
Which means exponents of each successive term will be in the reducing form and the last term will be a constant term.
Now we can rearrange the terms of the given polynomial (5x + 2x⁴ - 4) for the standard form.
(2x⁴ + 5x - 4)
Since, degree of the leading term = 4
And number of terms = 3
Given polynomial is a fourth degree trinomial.
Option (2) will be the answer.

9514 1404 393
Answer:
1:47:92:34:31:7Step-by-step explanation:
Reduced ratios are found by removing (dividing out) the greatest common factor (GCF). For several of these, that factor is the smallest number or the difference between the numbers. Knowledge of multiplication tables is helpful.
9 : 36 = 1 : 4 . . . . common factor of 9
21 : 27 = 7 : 9 . . . . common factor of 3
48 : 72 = 2 : 3 . . . . common factor of 24
60 : 45 = 4 : 3 . . . . common factor of 15
10 : 70 = 1 : 7 . . . . common factor of 10
_____
Comment on GCF
The greatest common factor can be found from your knowledge of multiplication tables and/or divisibility rules. It can also be found using Euclid's algorithm. For that, you ...
Divide the larger number by the smaller and keep the remainder.
If the remainder is 0, the smaller is the GCF.
If the remainder is not zero, replace the larger number with the remainder and repeat from the first step.
Example:
27/21 = 1 r 6
21/6 = 3 r 3
6/3 = 2 r 0 . . . . 3 is the GCF of 21 and 27
On her lunch break, Audrey grabs a meal with her two coworkers. If everyone paid an equal amount of $8.50, then how much was the total bill?
Answer:
$25.50
Step-by-step explanation:
3 people including Audrey went on the lunch break. If each spent $8.50, the total bill can be calculated in two ways
Method 1
$8.50 x 3 = $25.50
Method 2
$8.50 + $8.50 + $8.50 = $25.50
