d. BA≅AEFalse. There are no markings to indicate these segments are congruent.
e. CF, BE, AD intersect at point ATrue. Point A is shown as being on all of these lines and segments.
f. ∠BAC and ∠CAD are complementaryTrue. Ray AC splits right angle BAD, so these angles have a sum of 90°.
g. ∠DAE is a right angleTrue. Whenever a segment (AD) meets a line (BE) at right angles, both angles formed are right angles.
The equation 23+0.15p=c gives the cost c in dollars that a store charges to deliver an appliance that weighs p pounds. Use the equation and a table to find the weight of an appliance that costs $41 to deliver.
The weight of the appliance is 120 pounds.
What is equation?An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
23+0.15p=c
where the cost c in dollars that a store charges to deliver an appliance that weighs p pounds.
Now for c= 41
23 + 0.15p= 41
0.15p= 41-23
0.15p= 18
p= 18/0.15
p=120 pounds
Hence, the weight of an appliance is 120 pounds

The sum of three lengths of a fence ranges from 45 to 60 inches. Two side lengths are 9 and 18 inches. If the length of the third side is x inches, write and solve a compound inequality to show the possible lengths of the third side.
9 ≤ x ≤ 18
18 ≤ x ≤ 33
36 ≤ x ≤ 42
45 ≤ x ≤ 60
The solution to a compound inequality to show the possible lengths of the third side is 18 ≤ x ≤ 33
How to write and solve a compound inequality to show the possible lengths of the third side?The given parameters are
Range = 45 to 60 inches
Sides = 9, 18 and x
The sum of the three sides is
Sum = 9 + 18 + x
Evaluate
Sum = 27 + x
Recall that
Range = 47 to 60 inches
So, we have
45 ≤ 27 + x ≤ 60
Subtract through by 27
So, we have
18 ≤ x ≤ 33
Hence, the solution to a compound inequality to show the possible lengths of the third side is 18 ≤ x ≤ 33

OC. y-1-2(x+2)
D. y=2x-5
The equation of the line that do not pass through (6, 7)(2, -1) is y - 1 = 2(x + 2)
How to express equation of a line?The equation of a line can be express in different form. example includes slope intercept form and point slope form.
Let's express the equation in slope intercept form.
y = mx + b
where
m = slopeb = y-interceptTherefore,
(6, 7)(2, - 1)
m = -1 - 7 / 2 - 6
m = -8 / - 4
m = 2
Therefore, using (6, 7)
y = 2x + b
7 = 2(6) + b
b = 7 - 12
b = - 5
Hence,
y = 2x - 5
Therefore, in point slope form using (6, 7) and (2, -1)
y - y₁ = m(x - x₁)
y - 7 = 2(x - 6)
using (2, -1)
y + 1 = 2(x - 2)

Solve for c.
P=a+5+c
Answer:
c = P - a - b
Step-by-step explanation:
We are basically trying to get "c" by itself. If we ask ourselves what is with the "c" that we need to get rid of in order to have "c" by itself, we have a positive "a" and a "plus 5". To get rid of the positive "a" we subtract "a" from both sides. That leaves
P - a = 5 + c
To get rid of the "plus 5" we subtract 5 from both sides. That leaves
P - a - 5 = c

Last week, Abdul drove 211 miles. This week, he drove d miles. Using d, write an expression for the total number of miles he drove in the two weeks.
The total numbers of miles drove by abdul in two weeks in terms of k is: k+211 miles
The total number of miles that Abdul drove in two weeks will be the sum of the miles that he drove in week 1 + week 2
If he drove 211 miles one week, plus "d" miles the second week,
Let's call the total number of miles driven in two weeks k.
The sum of both weeks will be the total number of miles Abdul drove in two weeks should be as follows.
Given
no of miles drove in last week is 211 miles.
no of miles drove in current week is d miles.
So the total number of miles drove by Abdul in two weeks are:
Total no of miles drove in two weeks is 211+d miles.

The total numbers of miles drove by abdul in two weeks in terms of k is: k+211 miles

Solution : ADEBC
Arc: The length of any arc is s = r θ , where is the length of the arc, is the radius, and is the measure of the angle in radians. Use the fact that is equal to to convert between degrees and radians. A subtended arc is the part of the circle in between the two rays that make the central angle.
Arc length formula is used to calculate the measure of the distance along the curved line making up the arc (a segment of a circle). In simple words, the distance that runs through the curved line of the circle making up the arc is known as the arc length. It should be noted that the arc length is longer than the straight line distance between its endpoints.

Length of AB = 0.32
Here it is given that the length of BC = 2, and ∡ABC = 50°
The trigonometry formula is
cos Ф = base / hypotenuse
sin Ф = height / hypotenuse
cos 50° = 0.64
Here cos 50° = BC/ AB
Here we have to find the value of AB.
So we have
0.64 = 2/ AB
AB = 0.64/2
= 0.32
Therefore the length of AB is 0.32.
