What is the measure of ∠ABD?
Answer:
m∠ABD = 114°
Step-by-step explanation:
Given measurements of interior angles are:
m∠D = 2n°
m∠C = 60°
m∠ABD = (4n+6)°
The measurement of exterior angle of a triangle is equal to the sum of two opposite interior angles.
This can be mathematically expressed as:
m∠ABD = m∠C+m∠D
Putting the respective values
[tex]4n+6 = 2n+60\\4n-2n+6 = 60\\2n+6 = 60\\2n = 60-6\\2n = 54\\\frac{2n}{2} = \frac{54}{2}\\n = 27[/tex]
Putting n=27 in (4n+6)°
[tex]=4(27) + 6\\= 108+6 = 114[/tex]
Hence,
m∠ABD = 114°
How much interest is earned on $470 at 4% for 36 months?
Answer:
The interest earned on $470 at 4% for 36 months is $56.4
Step-by-step explanation:
We are given
Principal Amount P₀= $470
Rate r = 4% = 0.04
Time t = 36 months = 3 years
We need to find interest I
The formula used is: [tex]I=P_ort[/tex]
Putting values and finding Interest I
[tex]I=P_ort\\I=470(0.04)(3)\\I=56.4[/tex]
The interest earned on $470 at 4% for 36 months is $56.4

An exterior angle of a triangle is 152°. If the non-adjacent angles are congruent, then what are the measures of all of the interior angles of the triangle?
a. 62°, 59°, 59°
b. 90°, 45°, 45°
c. 152°, 14°, 14°
d. 28°, 76°, 76°
9514 1404 393
Answer:
d. 28°, 76°, 76°
Step-by-step explanation:
The sum of the "non-adjacent" interior angles of the triangle is equal to the exterior angle, so is 152°. If those angles are congruent, each is half of 152°, or 76°. The remaining angle is the supplement to 152°, so is 180-152 = 28 degrees.
The interior angles are 28°, 76°, 76°.

Function f is defined by the equation f (x) = x^2.
What is f (3)
PLZ HURRY
Answer:
f(3) = 9
Step-by-step explanation:
f(x) = x^2
f(3) means "When x is 3" So, we substitute x with 3.
f(3) = 3^2
f(3) = 3 x 3 = 9
f(3) = 9

Answer:
3.6
Step-by-step explanation:
260% of 6
100%= 0.06
100% times 2 is 0.06 X 2= 0.12
200%= 0.12
10%= 0.6
60%= 3.6
200% + 60%=
0.12 + 3.6= 3.72
The closest to 3.72 is 3.6
So the answer is 3.6
Answer:
To find this, multiply 6 by the decimal value of the percent.
6*2.6=15.6

Step-by-step explanation:
The equation y = 2x + 3/7 is in slope-intercept form: y = mx + b, where m = slope and b = y-intercept.
Note that m is the coefficient of x, and b is the constant.
The coefficient of x is 2, and the constant is 3/7.

Determine if the figure below has rotational symmetry, line symmetry or both and
describe the transformation that mas the figure onto itself. BE SPECIFIC. You must
name the center of rotation and degree of rotation if it has rotational symmetry or
lines of reflection if it has line symmetry
Answer:
A) Given that the figure is a rectangle, it has a rotational symmetry and by rotating the figure 180° about the center of the figure, the preimage and image will coincide
The figure also has a line symmetry for the vertical line x = 5, and a line symmetry for the horizontal line y = 5
Therefore the figure has both symmetry
B) The transformation that maps the figure unto itself are therefore;
1) Rotating the figure 180° about the point (5, 5) which is the center of the figure
2) Reflection of the figure across the line x = 5 and also reflection of the figure across the line y = 5
Step-by-step explanation:
can someone find the slope and y intercept ?
Answer:
Slope = -5/4
Y-Intercept = (0, -4)
Step-by-step explanation:
Step One: Determine two points.
In order to find slope, we have to find the amount of horizontal units (left and right) and vertical units (up and down) that two points are apart. We can choose any two points along this line to compare, so I'll use (0, -4) and (5, 0) since they align perfectly on the grid.
Step Two: Find the difference between the two points.
To find the differences, all we have to do is subtract the second point's X value from the first point's X value. So in this case, we would subtract 5 from 0, which gives us -5.
Next, we have to find the difference in our Y values, so we'll do the same thing here. We'll have 0 - (-4) (or 0 + 4, since subtracting a negative number is technically just addition), which ends up being 4.
Step Three: Put the differences into slope form.
Our slope form is Y/X, or you can think of it as "Rise/Run". We remember that our Y difference was -5, and our X difference was 4, so our end slope would be -5/4.
Step Four: Find the Y-Intercept
Since you have access to a graph of the line, the easiest way is to look at your graph and find the point where the line crosses the Y-axis (the black, vertical line where X = 0). From the graph, we can tell that the blue line crosses the Y-axis at (0, -4), so our Y-Intercept would be (0, -4)

sides of this triangle?
5 cm and 8 cm
6 cm and 7 cm
7 cm and 2 cm
8 cm and 9 cm
Answer:
8 cm and 9 cm
Step-by-step explanation:
x + y > 13
5 + 8 = 13
6 + 7 = 13
7 + 2 = 9
8 + 9 = 17
The last response is correct since they are greater than 13 cm

Answer:
Check boxes 3, 4, 6, and 8.
Step-by-step explanation:
We have the equation:
[tex]y=-3x+2[/tex]
And we want to select all equations that are perpendicular to the above equation.
Remember that perpendicular lines have slopes who are negative reciprocals of each other.
Therefore, the slope of our equations must be the negative reciprocal of -3.
The negative reciprocal of -3 is 1/3. We flipped -3 to -1/3, and then multiplied by a negative.
Therefore, any equation with a slope of 1/3 is perpendicular to our original line.
Therefore, we will check boxes 3, 4, 6, and 8.

A freight elevator can lift up to 2,000 pounds. The elevator is loaded with crates that weigh 85 pounds each. Which
inequality can be used to find the greatest number of crates, n, that the elevator can
lift?
LOOK AT THE PHOTO !
Answer:
n ≤ 2000/85
Step-by-step explanation:
Given that:
Weight in Pounds that elevator can lift ≤ 2000
Weight of each crate = 85 pounds
Greatest number of crates (n) elevator can lift ;
Weight per crate * number of crates ≤ 2000
85 * n ≤ 2000
85n ≤ 2000
n ≤ 2000/85

What is 45 percent of 37 A. 0.1665 B. 1.665 C. 16.65 or D 166.5
Answer:
The answer is C. 16.65 Hope that helps :)
45 percent of 37 is equal to 16.65. The correct answer is C) 16.65.
To find 45 percent of 37, we can multiply 37 by 0.45 since 45 percent is equivalent to 0.45 as a decimal.
37 * 0.45 = 16.65
Therefore, 45 percent of 37 is equal to 16.65.
The correct answer is C) 16.65.
The calculation represents taking 45 percent (or 0.45) of the value 37, resulting in the product 16.65. This means that if you were to take 45 percent of 37, you would obtain the value 16.65. It's essential to understand how to convert percentages to decimals to perform accurate calculations involving percentages.
