Answer:
no solution
Step-by-step explanation:
STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
[tex]7x+5-5x=12+2x-8[/tex]
STEP 2: Subtract 5x from 7x.
[tex]2x+5=12+2x-8[/tex]
STEP 3: Subtract 8 from 12.
[tex]2x+5=2x+4[/tex]
STEP 4: Move all terms containing x to the left side of the equation.
[tex]5=4[/tex]
STEP 5: Since 5≠4, there are no solutions.
No solution
Write the following expression in algebraic form.
cos(arcsin 3x)
Answer:
Step-by-step explanation:
If we consider a triangle with the length of the hypotenuse being equal to 1 and the length of the opposite side = 3x.
However, recall that in a right-angle triangle;
SIne = opposite/hypothenuse
Thus; let the angle facing the opposite be y
Then;
SIn y = 3x/1
Sin y = 3x
Thus, y = arcsin (3x)
Now; to find cos(arcsin 3x)
Recall that:
Cosine = adjacent/hypotenuse
Now, using Pythagoras rule;
[tex]\mathsf{Adjacent \ side = \sqrt{(hypotenuse)^2 -(opposite^2)}}[/tex]
[tex]\mathsf{Adjacent \ side = \sqrt{(1)^2 -(3x^2)}}[/tex]
[tex]\mathsf{Adjacent \ side = \sqrt{1 -9x^2}}[/tex]
cos(arcsin 3x) = cos y = adjacent side/hypotenuse = [tex]\dfrac{\sqrt{1 -9x^2}}{1}[/tex]
cos(arcsin 3x) = [tex]\dfrac{\sqrt{1 -9x^2}}{1}[/tex]

What percentage is equivalent to 2/5
Answer:
40 percent.
Step-by-step explanation:
Two-fifths is the same as 4/10, which is the same as 40/100. Since percentages are a part of 100, 40/100 is 40 percent.
The correct percentage that is equivalent to 2/5 would be 40%.
Used the concept of percentage of a number which states that,
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating the hundredth part of any quantity is called a percentage.
Given that the equivalent number is 2/5.
Let us assume that the percentage form of equivalent number = x
Hence, it can be written as,
x% = 2/5
x/100 = 2/5
Cross multiplying,
5x = 2 × 100
5x = 200
Divide 5 on both sides,
x = 200/5
x = 40
Therefore, 40% is equivalent to 2/5.

Please Help! Given triangles ABC and DEF, which statement explains a way to determine if the two figures are similar?
Verify corresponding pairs of angles are congruent by translation.
Verify corresponding pairs of sides are congruent by dilation.
Verify corresponding pairs of angles are congruent by dilation.
Verify corresponding pairs of sides are congruent by translation.
Answer:
A- Verify corresponding pairs of ANGLES are congruent by TRANSLATION.
Step-by-step explanation:
You find the congruent pairs by the angles, not the sides. Because the sides can be the same size but the angles can possibly not be congruent so you check by the angles. And Translation because you don't change the size of the object to see if it's congruent.
Similar triangles may or may not have congruent side lengths.
The true statement is: (a) verify corresponding pairs of angles are congruent by translation.
For the two triangles to be similar, the side lengths of both triangles may or may not be equal.
This means that: options (b) and (d) are not true
Translation does not alter side lengths and angles, while dilation alters measure of angles.
This means that:
The pair of corresponding angles should be checked by translating the triangles.
Hence, the true statement is: (a)

Kim creates a model of a building. The scale of her model building is 1 foot to inch. Some of the measurements are
shown in the table
Enter numbers in the empty boxes to correctly complete the table.
Building (feet) Model (inches)
Height
128
Length of Base
Width of Base
80
6.25
Answer:
height: 16 inch
length of base: 10 inch
width of base: 50 feet
Step-by-step explanation:
128*(1/8)=16 inch
80*(1/8)=10 inch
x*1/8=6.25
x=6.25*8=50 feet
The height and length of the model will be 16 in and 10 in respectively, and the width of the building will be 50 feet.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Given that, the scale factor of the building and a model of it is 1/8.
Height of the model = 128/8 = 16 in
Length of the model = 80/8 = 10 in
Width of the model = 6.25*8 = 50
Hence, The height and length of the model will be 16 in and 10 in respectively, and the width of the building will be 50 feet.

Step-by-step explanation:
Confidence Interval is the range around sample mean, likely to consist the population parameter.
Formula = x' + z (s / √n)

. For every 3 lemons Chrissy buys at a farm stand,
the total cost increases by $1.80.
The constant of proportionality is ?
An equation that relates the total cost, y, and the
number of lemons, x, is y = ? x.
Use the equation you wrote to complete the table.
Step-by-step explanation:
For every 3 lemons Chrissy buys at a farm stand, the total cost increases by $1.80.
cost or 1 lemon = 1.8/3 = $0.6
It means the constant of proportionality is 0.6
If there are x no of lemons, then the total cost will be given by :
y = 0.6x
Hence, this is the required solution.
Answer:
The answer is 0.6
