Answer:
$32
Step-by-step explanation:
200 + 57 = 257.
385 - 257 = 128
128 x 3/4 = 96 (deposited)
128 - 96 = 32

A store is going out of business, they are advertising that "Everything is 40% Off!" You have had your eye on a new pair of shoes that were originally $156. What is the sale price of the shoes?
Answer:
$93.6
Step-by-step explanation:
The original price if this show is to be sold at $156
But the question tells us that everything is being sold with a 40% off.
So we should get 40% of 156
= 0.40 * 156
= $62.4
So this shoe would have it's new price to be $(156 - 62.4) = $93.6
So in conclusion given a 40 percent off, the sales price if the shoe would be $93.6
What single percentage change is equivalent to a 12% decrease followed by a 18% increase?
Given:
12% decrease followed by a 18% increase.
To find:
The single percentage change is equivalent to the given set of percentages.
Solution:
Let the initial value be 100.
After 12% decrease, the value is:
[tex]v_1=100-\dfrac{12}{100}\times 100[/tex]
[tex]v_1=100-12[/tex]
[tex]v_1=88[/tex]
After 18% increase, the value is:
[tex]v_2=88+\dfrac{18}{100}\times 88[/tex]
[tex]v_2=88+15.84[/tex]
[tex]v_2=103.84[/tex]
The initial value is 100 and the new value in 103.84. So, it represents increase in the value. So, increase percentage is
[tex]Increase\%=\dfrac{\text{New -Initial}}{\text{Initial}}\times 100[/tex]
[tex]Increase\%=\dfrac{103.84-100}{100}\times 100[/tex]
[tex]Increase\%=3.84[/tex]
Therefore, the value increased by 3.84%.

then if x = 1
y = 1+ 4
so y = 5

Let y=f(x) be the particular solution to the differential equation dy/dx=2x−1/y^2 with the initial condition y(0)=3. Which of the following is an expression for f(x)?
A. √(x^2−x+9)
B. −3/3x^2−3x−1
C. (3x^2−3x)^1/3+3
D. (3x^2−3x+27)^1/3
Answer:
D. (3x^2-3x+27)^1/3
Step-by-step explanation:
dy/dx=2x−1/y^2
Cross multiply to get Y's and X's on different sides.
(y^2)dy = (2x-1)dx
Take the integral of each side
∫(y^2)dy = ∫(2x-1)dx
y^3/3 = 2x^2/2 - x + C
Multiply both sides by 3
y^3 = 3x^2 - 3x + C
Plug in (0,3) and solve for C
27 = 0 - 0 + C
C = 27
Plug in C to the equation
y^3 = 3x^2-3x+27
Cube root both sides to get just y
y = √(3x^2-3x+27)
y = (3x^2-3x+27)^1/3
D.
The particular solution of the equation will be "[tex](3x^2-3x+27)^\frac{1}{3}[/tex]".
Differential equationAccording to the question,
→ [tex]\frac{dy}{dx}[/tex] = [tex]\frac{2x-1}{y^2}[/tex]
By applying cross-multiplication,
(y²)dy = (2x - 1)dx
By integrating both sides, we get
→ ∫(y²) dy = ∫(2x - 1) dx
[tex]\frac{y^3}{3}[/tex] = [tex]\frac{2x^2}{2}[/tex] - x + C
By multiplying "3" both sides, we get
y³ = 3x² - 3x + c
By substituting "(0,3)" in above equation,
27 = 0 - 0 + C
C = 27
By substituting value of C in the above equation,
y³ = 3x² - 3x + 27
By cubing both sides,
y = √(3x²-3x+27)
= [tex](3x^2-3x+27)^\frac{1}{3}[/tex]
Thus the above answer i.e., "Option D" is correct.

A. ( -3, 4) , ( -4, 3 ) , ( -4, 1 ) , ( -2, -4 )
Answer:
B
Step-by-step explanation:
There isn't really much explaining I can do but each time you find the co-ordinate of a point you can cancel out a possibility.
For example, one of the points is (-3,4) and the only one without this point is C so that answer is cancelled out, and you keep going this way until you are left with only on possible answer and that should be B.
Top left = (-3,4)
Bottom left = (-2, -4)
Top right = (3,4)
Bottom right = (1,-4)
Write each number in standard form.
6.1 × 104
634.4 so the standard form is 600 + 30 + 4 + 0.4
Answer:
634.4 or 6.344*10^2
Step-by-step explanation:
When you're being asked to write an expression in standard form, the question probably wants you to simplify the expression or write it in scientific notation
Usually, in lower levels, you would simplify the expression, in which case you would multiply 6.1 by 104 using either a calculator (if you're allowed) or on paper to get 634.4
If you think your teacher wants you to use scientific notation, you would want to write your expression as a number under 10 multiplied by a power of 10. For example, if you were looking to write 6*8 in scientific notation/standard form, you would simplify for a product of 48, and turn that into 4.8*10. In your problem, you can multiply 6.1*104, and write your product of 634.4 as 6.344*10^2

Given the formula l = prt, where l = interest earned, P is the principal invested and r is the interest rate. If $245 is the principle invested at an interest rate of 3%, and Paul earned 69.80 interest, how long, t, (in years) was the money invested for?
Answer:
t= 9.49 years which can be estimated to 9 years
Step-by-step explanation:
Given the formula l = prt,
Where P is the principal=$245
r is the interest rate.=3%,
l = interest earned=$69.80
l = prt
Therefore time, t= I/ pr
t= 69.80/ 245 x 3%
t=69.80/ 245 x 0.03
t= 9.49 years which can be estimated to 9 years

Step-by-step explanation:
The shape on the left is translated to the shape on the right.
Shape M N O P Q R S is translated 6 units to the right.
Which statement about the transformation is true?
The name of the shape on the right is M N O P Q R S prime because it is the image of the shape on the left.
The name of the shape on the right is M N O P Q R S prime because it is the pre-image of the shape on the left.
The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the pre-image of the shape on the left.
The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.
Answer:
D.) The name of the shape on the right is M prime N prime O prime P prime Q prime R prime S prime because it is the image of the shape on the left.
Step-by-step explanation:
So the first thing we have to do is look at the information given, we know that the shape on the left is translated into the shape on the right. When a shape is "translated" it simply means that the shape doesn't change in size or rotation it only glides or moves. So the shape on the right is the former shape and the shape on the left is the pre-image.
Knowing that the left shape is the pre-image goes ahead and eliminates answer choices B & C as both answers mention that the right side is the image before the transformation which because of what was previously mentioned, is incorrect.
This leaves only answer choices A and D. Finally we can narrow down the final answer by knowing that the apostrophe " ' " or prime should be placed after each letter not just at the end of letters. For example A'B'C'D' not ABCD'. If we apply this rule to the last to answer choices we can see that D is the correct answer.
