Which of the following is being constructed in the image?
A) a line perpendicular to a given lune through a point on the line
B) a line segment that is congruent to a given line segment
C) a perpendicular bisector of a line segment
D) a line parallel to a given line through a point not on the line
Answers
Answer:
A) a line perpendicular to a given line through a point on the line.
Step-by-step explanation:
Perpendicular means at a 90 degree angle.
As we can see, the arcs are crossing on a dotted line that is going through a point, and is perpendicular to the line the point is on.

Answer:
The remainder of 8439 divided by 245 is 109.
Step-by-step explanation:
Given two numbers as 8439 and we have to divide it by 245.
That is , Dividend = 8439
Divisor = 245
Solution:
Using division algorithm,
Dividend = ( Divisor * Quotient )+Remainder
8439 = (245*34)+Remainder
8439 =8330+Remainder
Taking 8330 to other side to find the remainder, we have
8439 -8330 = Remainder
109 = Remainder
Thus The remainder of 8439÷245 is 109.

Which expression is equivalent to −2.6+(−2.9)+(−7.1) ?
Answers
=−5.5+7.1
=1.6
Answer:
-12.6
Step-by-step explanation:
To evaluate the given expression
-2.6+(−2.9)+(−7.1, first we will open out the brackets and multiply the signs. Before that, we must take note of the following sign operations
-×- = +
-×+ = -
+×- = -
+×+ = +
The equation above becomes;
-2.6-2.9-7.1 (all the signs are now minus since the product of plus and minus sign gives a minus sign)
(-2.6-2.9)-7.1
= -5.5-7.1
= -12.6
Since all the values in the equation are negative values, our resulting answer will be a negative value.

GIVEN: ab perpendicular to BC AND DC PERPENDICULAR TO BC
AC = BD
PROVE:AB =DC
Proofs
Answers
1. angles : B=C=90° because they are right triangles (AB perpendicular to BC and DC perpendicular to BC)
2. AC=BD (given)
3. BC is in common (the two triangles have it, you can say it like BC=BC)
So we proved that by SAS(side angle side), the triangles are congruent ABC= DCB
Since the triangles are congrueny, all their sides are equal so we can say that AB=DC
Answer with Step-by-step explanation:
We are given that AB is perpendicular to BC and DC perpendicular to BC.
AC=BD
We have to prove that AB=DC
In triangle ABC and triangle DCB
AC=BD (Given)
[tex]\angle B=\angle C=90^{\circ}[/tex]
[tex]BC=BC[/tex]
Reason:Reflexive property
[tex]\triangle ABC\cong \triangle DCB[/tex]
Reason:RHL postulate
[tex]AB\cong DC[/tex]
Reason:CPCT
Therefore, AB=DC when two sides are congruent then the sides are equal.
Hence, proved.
A spinner is separated into 3 equal pieces, as shown below: A spinner is shown with three colors, red, yellow, and purple, marked on it. The arrow points towards the red color. Mary spins the spinner 6 times. What is the theoretical probability that it stops on the red sector on the last spin?
Answers
If he spins it six times, 6/20 is the chance he will spin red. Which that lowers to 1/3.
The theoretical probability that it stops on the red sector on the last spin is 1 by 3.
Calculation of the theoretical probability:Since A spinner is separated into 3 equal pieces. A spinner is shown with three colors, red, yellow, and purple, marked on it. Mary spins the spinner 6 times.
So, the theoretical probability is
Probability= Successful outcome ÷ Possible outcome
= 1÷3
Therefore, The theoretical probability that it stops on the red sector on the last spin is 1 by 3.

what is the momentum of a 20-kg dog running at a speed of 8 m/s
Answers
P=mv
=(160 kg m/s)
The momentum of a 20-kg dog running at a speed of 8 m/s is 160 kg.m/s. This is calculated using the formula for momentum, which is the product of mass and velocity.
Explanation:To calculate the momentum of an object, you need to multiply its mass by its velocity. This is due to the fact that momentum is directly proportional to the object's mass and its velocity. Hence, a 20-kg dog running at a speed of 8 m/s would have a momentum of 160 kg.m/s.
Momentum (p) is represented as the product of mass (m) and velocity (v), hence expressed as p = m*v. Momentum is a vector quantity, which means it has both magnitude (amount) and direction. In this case, we're only concerned with its magnitude.
So, for the 20-kg dog running at 8 m/s, we substitute these values into the momentum formula to find its momentum:
p = m*vp = 20kg * 8 m/sp = 160 kg.m/sLearn more about Momentum here:https://brainly.com/question/30677308

Danielle has a CD at crossland bank. she invest $22,350 for four years at 4.55% interest. compounded monthly. What is her ending balance? How much interest did she make?
Answers
$1,016.925 x 4 = $4,067.70 (amount of interest earned over 4 years)
$22,350 + $4,067.7 = $26,417.70 (ending balance)
Answer: Her ending balance is $26,703.837 and her interest is $4,353.837
Step-by-step explanation:
First year,
p =22350 R = 4.55 T = 1
Interest = PRT/100
= 22350 × 4.55 × 1 / 100
=$1016.925
P = $22350 + $1016.925 = $23366.925
For the 2nd year,
I = $23366.925 × 4.55 × 1 / 100
=$1063.195
p= $23366.925 + $1063.195 = $24,430.12
For the 3rd year,
I = $24,430.12 × 4.55 × 1 / 100
= $1111.57
p = $24,430.12 + $1111.57 = $25,541.68
For the 4th year;
I = $25541.68 × 4.55 × 1 / 100
= $1,162.147
P = $ 25541.69 + $1,162.147 = $26,703.837
Therefore th ending balance is $26,703.837
Her compound interest is , $26,703.837 - $22350 =$4,353.837

Answers
if after the concert, their profit is 304$ then I believe the way to solve it would be 304/12 which equals 25.3
However, they did not make a profit off of the 10 shirts that they gave away. 10*12 equals 120
304-120 equals 184
184/12 equals 15.
Your answer should be either 25 or 15

If a player always gets three cards, describe two different ways to recieve a score of 7.
Answers
Answer:
1 + 3 + 3 = 7
5 + 1 + 1 = 7
Step-by-step explanation:
If a player have the three cards. Each card will have a number and we have to find the numbers on each card that total 7.
Let card 1 gets 1
Then other two cards may have 3 and 3
So, 1 + 3 + 3 = 7
Now we take another combination which totals 7
5 + 1 + 1 = 7
Therefore, there may be two different ways are
1 + 3 + 3 = 7
5 + 1 + 1 = 7
In a recent year, the population of California was about 2.52 x 10^7 people. Its land area is about 4.05 x 10^5 km^2. What was the average number of people per square kilometer? Write your answer in scientific notation.
PLEASE I NEED HELP ASAP!!!!!!!!!!!!
Answers
The average number of people per square kilometer in California is [tex]6.22 \times 10^1.[/tex]
To find the average number of people per square kilometer in California, we divide the total population by the land area.
Given:
Population of California = [tex]2.52 \times 10^7[/tex] people
Land area of California = [tex]4.05 \times 10^5 km^2[/tex]
Calculate the population density.
Population density = Population / Land area
Population density = [tex](2.52 \times 10^7) / (4.05 \times 10^5) people/km^2[/tex]
Divide the numbers and simplify.
Population density = (2.52 / 4.05) x 10^(7-5) people/km^2
Population density = [tex]0.622 \times 10^2 people/km^2[/tex]
Rewrite in scientific notation.
Population density = [tex]6.22 \times 10^1 people/km^2[/tex]
So, the average number of people per square kilometer in California is [tex]6.22 \times 10^1[/tex].
Two events, X and Y, are independent of each other. P(Y) = 5/6 and P(X and Y) =1/3 . What is P(X) written as a decimal?
Answers
Since they are independent, P(X & Y) = P(Y) * P(X)
Therefore:
1/3 = 5/6 * P(X) Change 1/3 to 2/6, then multiply both sides by 6/5
2/6 * 6/5 = P(X)
2/5 = P(X)
Written as a decimal, P(X) = .40
