Complete each congruency statement and name the rule used. If you cannot show the triangles are congruent from the given information, leave the triangle's name blank and write CNBD for "Cannot be determined" in place of the rule. GA ∩ TN = I ∆GIT ≅ ∆_____ by _____
Answer:
The correct answer is;
ΔGIT≅ ΔNIA by Side Angle Side (SAS) rule of congruency
Step-by-step explanation:
The given information are;
The point of intersection of GA ∩ TN = I
Segment TI is congruent to segment NI (Given)
Segment GI is congruent to segment IA (Given)
Angle ∠GIT is congruent to angle ∠AIN (Vertically opposite angles)
Therefore, we have;
Triangle, ΔGIT is congruent to triangle ΔNIA (Side Angle Side (SAS) rule of congruency)
Two triangles are said to be congruent by the Side Angle Side (SAS) rule of congruency, when two of the sides and the included angle (the angle in between the two sides) of one of the triangle are equal to two sides and the included angle of the other triangle.
Therefore, the correct answer is ΔGIT≅ ΔNIA by Side Angle Side (SAS) rule of congruency
Answer:
△GIT≅△AIN
By Rule: SAS

Answer:
x = 13
RQ = 160°
Step-by-step explanation:
Inscribed angles are half the intercepted arc angle.
5x + 15 = ½ (RQ)
RQ = 10x + 30
Arc angles add up to 360°.
10x + 30 + 9x + 17 + 6x − 12 = 360
25x + 35 = 360
25x = 325
x = 13
Therefore, RQ = 160°.
An secondary school have 250 students 30% in the First grade secondary and 35% Second grade secondary.
how many students in the Third grade are there
Answer:
Third grade secondary = 87 students
Step-by-step explanation:
First grade = 30/100 x 250 = 75 students
Second grade = 35/100 x 250 = 87.5 rounded off to 88 students. Because students can't be half thus can't be in decimal. So round off to the nearest whole number.
Third grade = 250 - 88 - 75 = 87 students
Answer:
third grade secondary = 87 students

What is the range of the function shown in the graph below? answer type: interval, all real values except one, all real values except two, all real numbers
Interval:
The Range of f(x) → Range ∈ [- 4, ∞).
We have a graph of a function f(x) given.
We have to determine the range of f(x).
What is Domain and Range of any function?The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
According to the question -
We can see that the function is defined for all values of x (assuming that the graph will continue after the arrows at the top). Hence, the domain of f(x) will be set of all real numbers.
Now, the graph curves back after reaching a minimum value of -4. Therefore, the set of all possible values f(x) takes belongs to the set
[-4, ∞).
Hence, the Range of f(x) → Range ∈ [- 4, ∞)

Step-by-step explanation:
Answer:
f^-1(x) = x/5 - 12/5
Step-by-step explanation:
f(x) = 5x + 12

The height of a kicked football can be represented by the polynomial –16t2 + 47t + 3 = 0, where t is the time in seconds. Find the time in seconds of when the football hits the ground.
Step-by-step explanation:
-16t2 + 47t + 3 = 0
-16t2 + 48t - t + 3 = 0
-16t( t - 3) - 1 ( t - 3) = 0
-16t - 1 = 0. t - 3 = 0
-16t = 1 t = 3

f(g(2)) = f(0) = -2
g(f(1)) = g(0) = 0
Answer:
The correct answers for both of them is -2 and 0.
Step-by-step explanation:
I)
[tex](f\circ g)(2)=f(g(2))[/tex]
From the red graph, we can see that g(2) is 0.
Therefore, f(g(2)) is equal to f(0).
And from the blue graph, we can see that f(0) is -2.
Therefore:
[tex](f\circ g)(2)=-2[/tex]
II)
[tex](g\circ f)(1)=g(f(1))[/tex]
From the blue graph, we can see that f(1) is 0.

Which of the following numbers is divisible by 24 ? (A) 13,944 (B) 15,746 (C) 15,966 (D) 16,012 (E) none of the above
Answer:
Only A is divisible by 24.
Step-by-step explanation:
A number is divisible by 24 if it's divisible by both 3 and 8.
Numbers are divisible by 3 if all their digits add to a multiple of 3, and numbers are divisible by 8 if the last 3 digits are divisible by 8.
Let's look at A, 13944. The numbers add up to [tex]1+3+9+4+4=21[/tex], which is divisible by 3.
944 is divisible by 8, and it makes 118.
So A works.
B is 15746.
[tex]1+5+7+4+6=23[/tex], so this won't work as 23 isn't divisible by 3.
C is 15966.
[tex]1+5+9+6+6=27\div3=9[/tex], so this works for 3 but let's check 8.
[tex]966\div8=120.75[/tex] so it's not divisible by 8, therefore not divisible by 24.
D is 16012.
[tex]1+6+0+1+2=10[/tex] and 10 isn't divisible by 3, so it doesn't work.

Slim Johnson was usually the best free-throw shooter on his basketball team. Early in the
season, however, he had made only 9 of 20 shots. By the end of the season, he had made all
the additional shots he had taken, thereby ending with a season record of 3:4. How many
additional shots had he taken?
Answer:
24
Step-by-step explanation:
(9 + x)/(20 + x) = 0.75
Solve that for x, the number of additional free throws taken.
9 + x = 15 + 0.75 x
0.25 x = 6
x=24
The required number of additional shots that were shot is 24.
Given that,
He had made only 9 of 20 shots. By the end of the season, he had made all the additional shots he had taken, thereby ending with a season record of 3:4.
The ratio can be defined as the comparison of the fraction of one quantity towards others. e.g.- water in milk.
Here,
Let the extra shots be x,
Now, according to the question,
Number of shots will be 9 + x and 20 + x,
And their ratio is 3:4
9 + x / 20 + x = 3 / 4
[9 + x] × 4 = 3 [20 + x]
36 + 4x = 60 + 3x
x = 60 - 36
x = 24
Thus, the required number of additional shots that were shot is 24.

PLEASE ANSWER ASAP The drama club is selling candles for a fundraiser. They spend $100 on the candles and sell them for $4.50 each. How many candles must they sell to make more than $125 profit? Let x represent the number of candles sold. Which inequality can you use to find x? 4.5x – 100 > 125 4.5x + 125 > 100 100 – 4.5x > 125 100 + 4.5x > 125
Answer: 4.5x-100 > 125
Step-by-step explanation: Each candle costs $4.50, which can be simplified to 4.5. To determine how much they will make from the candles, you want to multiply the cost of the candles (4.5) by how many candles are sold (x), and this is where the 4.5x comes from. We subtract 100, because that is how much they spent on the candles they are selling (profit means how much you make after expenses). Since they're trying to make MORE THAN $125 in profit, we use the > sign.
Answer:
So we know that they spend $100 on the candles. In order to make a $125 profit, they must sell $225 worth of candles. Each candle sells for $4.50, so: So we know that they spend $100 on the candles. In order to make a $125 profit, they must sell $225 worth of candles. Each candle sells for $4.50, so:
4.5x > 225 is the inequality for that. It just means $4.50 times the number of candles has to be more than the $225 we need. To simplify it, just divide both sided by 4.5:
x > 50
They have to sell more than 50 candles.

Jamaal spent x minutes today practicing his guitar and y minutes today on homework. If the total time he spent on both is 45 minutes or more, which inequality best represents his practice time?
x + y < 45
x + y > 45
x + y ≤ 45
x + y ≥ 45
Answer:
x + y ≥ 45
Step-by-step explanation:
This is because the total amount of minutes could be equal to 45, meaning your inequality sign has to have a line underneath it.
Additionally, x + y is greater than or equal to because the amount could be more than 45... therefore, 45 is not greater than x + y

1. 0.01 divided by 1,000= 100,000.000
Change the divisor 0.01 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
100000 ÷ 1 = 100,000.000
and therefore:
1,000 ÷ 0.01 = 100,000.000
Both calculated to 3 decimal places.
2. 0.012 divided by 100= 8,333.333
Change the divisor 0.012 to a whole number by moving the decimal point 3 places to the right. Then move the decimal point in the dividend the same, 3 places to the right.
We then have the equations:
100000 ÷ 12 = 8,333.333
and therefore:
100 ÷ 0.012 = 8,333.333
Both calculated to 3 decimal places.
3. 0.000851 divided by 10= 11,750.881
Change the divisor 0.000851 to a whole number by moving the decimal point 6 places to the right. Then move the decimal point in the dividend the same, 6 places to the right.
We then have the equations:
10000000 ÷ 851 = 11,750.881
and therefore:
10 ÷ 0.000851 = 11,750.881
Both calculated to 3 decimal places.
