Answer:
A
Step-by-step explanation:
The correct equation to find 40 percent of 25 is: D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction
Let's go through each option and determine the correct equation step by step.
A. Start Fraction 25 divided by 1 Over 40 divided by 1 End Fraction = Start Fraction 25 Over 40 End Fraction
This equation represents the division of 25 by 40. However, we want to find 40 percent of 25, not divide 25 by 40. So, this equation is not the correct one.
B. Start Fraction 100 times 4 Over 40 times 4 End Fraction = Start Fraction 400 Over 16 End Fraction
In this equation, we multiply 100 by 4 and divide it by 40 multiplied by 4. Simplifying this expression, we get 400 divided by 16, which is equal to 25. This equation does not give us the value of 40 percent of 25, so it is not the correct one.
C. Start Fraction 40 times 4 Over 25 times 4 End Fraction = Start Fraction 160 Over 100 End Fraction
Here, we multiply 40 by 4 and divide it by 25 multiplied by 4. Simplifying this expression, we get 160 divided by 100, which is equal to 1.6. This equation does not give us the value of 40 percent of 25, so it is also not the correct one.
D. Start Fraction 40 divided by 4 Over 100 divided by 4 End Fraction = Start Fraction 10 Over 25 End Fraction
In this equation, we divide 40 by 4 and divide 100 by 4. Simplifying this expression, we get 10 divided by 25, which is equal to 0.4. This equation represents 40 percent of 25, as 0.4 is equal to 40 percent when expressed as a decimal. Therefore, the correct equation is D.

Sam noticed that some people purchased like items and decided to start offering a bundle. If you buy the following items together, you get 15% off. How much will the bundle cost? $11.00 snorkle $30.00 for goggles $36.00 for flipperd
Answer: $65.45
Step-by-step explanation:
Cost of Snorkle = $11.00
Cost of goggles = $30.00
Cost for flippered = $36.00
Total cost = $11.00 + $30.00 + $36.00 = $77.00
Since there's a 15% off, the cost of the bundle will be:
= $77 - (15% × $77)
= $77 - (0.15 × $77)
= $77 - $11.55
= $65.45
What is the image point of (-1, -3) after
By using the translation formula, the image point of (- 1, - 3) is equal to the point (2, 1).
How to determine the coordinates of the image of a point by using a translation formula
In this problem we find the coordinates of a point, whose image must be found by using a translation, a kind of rigid transformation. The formula for the determination of the coordinates of the image is introduced below:
P'(x, y) = P(x, y) + T(x, y) (1)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointT(x, y) - Translation vectorIf we know that P(x, y) = (- 1, - 3) and T(x, y) = (3, 4), then the coordinates of the resulting point according to the transformation rule are:
P'(x, y) = (- 1, - 3) + (3, 4)
P'(x, y) = (2, 1)
The image point of (- 1, - 3) is equal to the point (2, 1).

how do you solve 6x+104=16x+114
Answer:
x = -1
Step-by-step explanation:
6x + 104 = 16x + 114
First subtract 104 from both sides
Now you have:
6x = 16x + 10
Subtract 16x from both sides
-10x = 10
Divide by -10 on both sides and you get your answer
x = -1
Answer:
x = - 1
Step-by-step explanation:
First you wanna subtract 104 from both sides
6x + 104 - 104 = 16x + 114 - 104
you should get 0 on the left and 10 on the right
next you subtract 16x from both sides
6x - 16x = 16x - 16x + 10
you should get -10x on the left side and get 0 on your right
next you divide both side by -10
-10x ÷ -10 = 10 ÷ -10
the left should be 0 and the right should be -1
that's how i got the answer and I hope it helped !
An angle's measure is 43 less than 6 times the measure of its
complement. Find the measure of both angles,
Step-by-step explanation:
A = 6(90-A)-43 Simplify and solve for A.
A = 540-6A-43
A = 497-6A Add 6A to both sides.
7A = 497 Divide both sides by 7.
A = 71 degrees
The complement of A = 90-A = 09-71 = 19

a) dependent variable; random
b) dependent variable; based on preexisting differences
c) independent variable; based on preexisting difference

In a true experimental design, the manipulated variable, or grouping variable is independent variable; based on pre-existing difference.
What is the independent variable?The independent variable is the variable in an experiment that is manipulated by the researcher. It is assumed that the independent variable has a direct effect on the dependent variable. The dependent variable is the variable whose value is being determined in the experiment.
For example, you want to carry out an experiment to determine the effect of the hours spent reading for a test on the grade gotten on the grade. In this research, the independent variable is the hours spent reading and the dependent variable is the grade gotten. Different data on the hours studied would be collected.
