In ∆ABC, ∠A is a right angle, and ∠B measures less than 40°. Which of the following phrases best describes the measure of ∠C?
Answers
The phrase that describes the measure of ∠C is greater than 50°.
What is a right triangle?A right triangle is a triangle that has one of its angle as 90 degrees.
The triangle is named as ABC.
∆ABC
where
∠A = 90 degrees
∠B < 40 degrees
The sum angles in a triangle is 180 degrees.
Therefore,
let x be the third angle
Hence,
∠A + ∠B + ∠C = 180°
∠B + ∠C = 180 - 90
∠B + ∠C = 90°
∠B < 40 degrees
Therefore,
∠C > 50 degrees.

Use the equation y = x - 2 and perform a reflection over the x-axis. Write an equation in 2
1
slope intercept form that represents the new line.
Answers
Answer:
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2Step-by-step explanation:
Given the equation
[tex]y = x - 2[/tex]
Reflecting over the x-axis inverts the sign of the y-coordinate, but the sign of the x-coordinate remains the same.
So after reflecting over the x-axis, the equation is:
[tex]-y = x-2[/tex]
Now, writing the equation in the slope-intercept form
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
so the equation in the slope-intercept form
[tex]-y = x-2[/tex]
[tex]y=-x+2[/tex]
Here,
The slope = m = -1The y-intercept = b = 2Shayna enlarged a square photo by adding 10 inches to each side so it could be seen on a large poster. The area of the enlarged photo is 256 square inches. In the equation (x + 10)2 = 256, x represents the side measure of the original square photo.
What were the dimensions of the original photo?
pls hurry
4 inches by 4 inches
6 inches by 6 inches
10 inches by 10 inches
12 inches by 12 inches
Answers
Answer:
The correct answer is:
6 inches by 6 inches
Step-by-step explanation:
Given that
Area of Enlarged photo = 256 square inches
Let x be the side of original photo
then the equation for area of new enlarged photo will be:
[tex](x+10)^2 = 256[/tex]
We have to solve the given equation to find the side length of original photo
Taking square root on both sides
[tex]\sqrt{(x+10)^2} = \sqrt{256}\\x+10 = 16[/tex]
Subtracting 10 from both sides
[tex]x+10-10 = 16-10\\x = 6[/tex]
So the side length of original photo is 6 inches. The dimensions will be 6 inches by 6 inches.
Hence,
The correct answer is:
6 inches by 6 inches

Given CAD is a right angle and AB is bisecting CAD and if DAB=(7x-4) find X
Answers
Answer:
7°
Step-by-step explanation:
Just a quick clarification, swap A and B on the diagram.
If CAD is a right angle, it is equal to 90°. Since AB is bisecting CAD, angles CAB and DAB are congruent(equal) and complementary(add up to 90) angles, and thus equal 45°. By the transitive property, if DAB = (7x - 4)° and also equals 45°, (7x - 4)° = 45°. So we can simply solve for x.
7x - 4 = 45
7x - 4 + 4 = 45 + 4
7x = 49
7x/7 = 49/7
x = 7

I think it's answer choice A!
Step-by-step explanation:
The reason why I think that it is A is because of the given y values. The x values are consistent through all of the given choices, but if graphed, there is a distance of three units between the y-value of 4 and the y-value of 7. I personally like to use Desmos when it comes to trying to get a visual graph of coordinates. I hope this at least helped a little!
The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units, therefore, option (A) will be correct.
How to find the distance between two points?Let's consider we have two points (x₁, y₁) and (x₂, y₂) the distance between these two points is given by the formula;
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
The distance between with two points (x₁, y₁) and (x₂, y₂) is given as,
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
In option (A),
Points are (2,4) and (2,7).
The distance between them will be,
[tex]d = \sqrt {\left( {2 - 2 } \right)^2 + \left( {4 - 7 } \right)^2 }[/tex]
d = √(3²) = 3
Hence "The distance between (2,4) and (2,7) is 3 therefore, these two points have a distance of 3 units".

savings deposit for 3 years. At the end of 3 years, how much more

Step-by-step explanation:
Lets find out,shall we?
Simple interest=(PRT)/100
=$1000×12×3)/100
=$360
Now for compound interest
A=P(1+R/100)^t
A=$1000(1+12/100)^3
A=$1404.928
so interest for compound interest=$(1404.928-1000)=$404.928
Clearly,Robin got more interest by compound interest than simple interest which business people understand lol.
Difference in interest=$404.928-360=$44.928

Answers
Domain of the function is: 0 < x < 12.
Volume of the box = 4x(12-x)²cm^3
Volume of a cuboid:Volume is the measure of how much space a given substance takes up inside a closed, three-dimensional object. A cuboid's volume given by its length (l), breadth (b), and height (h) is as follows:
According to the given data:Side of square = 24cm
(a) Volume of the box
Let the squares used to create a box have a side of "x" cm.
so,
length will be = 2(12 - x)
Width will be = 2(12 - x)
Hight will be = x
Volume of the Square box (V) = l x b x h
= 2(12 - x) * 2(12 - x) * (x)
= 4x(12-x)²cm^3
(b) The domain of the function V(x)
We see that:
x is length, x >0
x cm of the side's length of 24 cm are removed from both ends.
so that 2x<24
