Answers
hope it helps
Answer:
Triangle 4
Step-by-step explanation:
Congruent triangles are identical in all aspects. They have identical sides and angles.
The ASA the Angle Side Angle criterion.
Congruent triangles should be able to "close up" on each other if one triangle is placed on top of the other. Let's look at the triangle in question.
The triangle ABC is made distinct by the lines on it.
The lines mark the different angles on the triangle.
By looking at the triangle and comparing, Triangle satisfies the ASA criterion

What are the solutions to the inequality? Graph the solutions. x/5 greater than or equal to -2
Answers
">" is the greater than sign, and ">" means it is greater than or equal to since it is underlined. All you have to do now is put the inequality into slope-intercept form (y = mx + b) and plot the line on a graph.
In this inequality, -2 is y and x/5 is x. Just rearrange the terms while still keeping the answer the same.
x/5 > -2
-2 < x/5 Notice that the sign changed to "less than or equal to." This is because x/5 is still greater than or equal to -2, which makes -2 less than or equal to x/5.
Since it is "or equal to," we can discover what x could be by multiplying -2 by 5, which is -10. So the non-dotted line goes over the point -10 on the x-axis, straightly vertical without a slope, and everything that is greater than -10 is shaded, which is everything on the right side of the line.

Maria gathered the data in the table. She finds the line of best fit to be y = 2.78x – 4.4. What is the residual value when x = 4?
Answers
You plug 4 into the line of best fit and get 6.72. This is your predicted value, but the residual is the difference between the actual value and predicted. So you subtract: 7.3-6.72=0.58.
Solution:
The line of best fit is given as y=2.78x-4.4
We need to find the residual value when x=4.
The residual value is an estimate of the wholesale value .To find the residual value we plug in x=4 in the given line of best fit.The corresponding y value will give the predicted value.
y=2.78x-4.4
Substituting x=4,
y=2.78(4)-4.4
y=11.12-4
y=7.12.
The predicted value when x=4 is y=7.12.
Residual value = predicted value - Actual value -=7.12 - actual value.

Step-by-step explanation:
Given : ΔABC with vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise about the origin.
To find : What are the coordinates of the vertices of the image.
Solution : We have given
Vertices A(-3, 0), B(-2, 3), C(-1, 1) is rotated 180° clockwise.
By the rotation rule of 180° clockwise : (x ,y) →→ ( -x ,-y).
Then vertices would be
A(-3, 0) →→ A(3, 0)
B(-2, 3) →→ B(2, -3)
C(-1, 1) →→ C(1, -1).
Reflection y = -x then
A(0, -3) ; B(3, -2) and C(-1, 1).

Which expression is equivalent to square root of 9x^2?
Answers
√(9x^2)
To make this easier, let's use the following property of roots.
√(ab) = √(a) * √(b)
Let's separate the square root into two different square roots.
√(9x^2)
= √(9) * √(x^2)
Now, let's solve for each square root individually.
√(9) = 3
√(x^2) = x
Now, combine them
3 * x = 3x
3x is your answer.
Have an awesome day! :)
You can think of 3*3*x*x as 3x*3x which is (3x)^2.
Now we can take the square root of (3x)^2 (which equals 9x^2).
√(3x)^2
The √ and the ^2 cancel out so you are left with 3x.
So, √9x^2 = √(3x)^2 = 3x.

Step-by-step explanation:
A cross section is the shape that we get when we cut the object.
Here the given object is a cube.
It is cut straight through the middle.
Imagine a cube cut through the middle, when we look at the same on the top, we get square.
Since in a cube all the sides are equal.
Therefore, we get square when we cut the cube straight through the middle.
Answer: D. Square.
The cross-section of the shape in the image is a square.
Here's why:
The shape in the image is a cube.
A cube has six square faces.
When you cut a cube through the middle along any of its axes, the resulting cross-section will always be a square.

A checkers board is 8 squares long and 8 squares wide. The area of each square is 14 square centimeters. Estimate the perimeter of the checkers board to the nearest tenth of a centimeter.
Answers
Area of each square = 14 sq. cm.
length of each square = sqrt(14) = 3.7 cm
length of one side = 8 x 3.7 = 29.6 cm
Perimeter of the checker board = 4 x 29.6 = 118.4 cm

Elliott purchased shares of Microsoft in 2008 for $28 per share. He plans to sell them as soon as the price rises 20%. At what price will he sell his shares?
Answers
Since we are to find the price when it is risen 20%, therefore the fractional increase must be 0.20 of the original, therefore:
amount increased = $28 * 0.20 = $5.60
So the selling price must be:
selling price = $28 + $5.60 = $33.60
Final answer:
Elliott will sell his Microsoft shares at a price of $33.60 each after a 20% price increase from his initial purchase price of $28 per share.
Explanation:
The question concerns the calculation of a future selling price of shares after a certain percentage increase. To find the selling price after a 20% increase on Elliott's initial purchase price of $28 per share, we first calculate the 20% increase, which is 0.20 × $28 = $5.60. Next, we add this increase to the original purchase price to determine the selling price: $28 + $5.60 = $33.60 per share. Therefore, Elliott plans to sell his shares when their price reaches $33.60 each.

In triangle ΔABC, ∠C is a right angle and CD is the height to AB, Find the angles in ΔCBD and ΔCAD if: m∠A = α
m∠DBC =
m∠DCB =
m∠CDB =
m∠ACD =
m∠ADC =
Answers
Given:
m∠C = 90°, because ∠C is a right angle.
m∠D = 90°, because CD is the height to AB.
m∠A = α
Because the sum of angles in a triangle is 180°, therefore
m∠DBC + 90° + α = 180°
m∠DBC = 90° - α
Again, for the same reason,
m∠DCB + m∠DBC + 90° = 180°
m∠DCB + 90° - α + 90° = 180°
m∠DCB = α
For the same reason,
m∠ACD + 90° + α = 180°
m∠ACD = 90° - α
m∠ADC = 90° (by definition)
m∠CDB = 90° (by definition)
Answer:
m∠DBC = 90° - α
m∠DCB = α
m∠CDB = 90°
m∠ACD = 90° - α
m∠ADC = 90°
