Answer:
B. 63
Step-by-step explanation:
There are two similar triangles given in the diagram above. Since they area similar, they also have corresponding side lengths that are proportional.
Therefore:
(6 + 3)/3 = x/21
9/3 = x/21
3 = x/21
Cross multiply
21*3 = x
63 = x
x = 63

Answer: Choice B) SAS
=======================================================
Explanation:
The sides that have the double tickmarks are the same length. This forms one "S" of "SAS".
The square angles are 90 degree angles, or right angles. They are congruent. This forms the "A" of "SAS".
The overlapping sides are the same length, which forms the second "S" of "SAS".
The angle is between the two sides allowing us to use SAS. The order is important.

Answers
Answer:
Smallest number of rows that is needed to seat these people = 16
Step-by-step explanation:
Given - A theatre has seats arranged in rows of 24, three hundred eighty -two(382) people attend a show at the theatre.
To find - What is the smallest number of rows that is needed to seat these people?
Solution -
Given that,
Total number of seats in a Row = 24
Let us assume that, there are x rows
As.
There are 382 people in the Theatre
So,
Minimum seats required is
24 x = 382
⇒x = 382 ÷ 24
⇒x = 15.91
i.e.
Smallest number of rows that is needed to seat these people = 16

P 2.680 S 2.920 T 4.200
Step-by-step explanation:
S = seconde
Premiere = S-240
Troisieme = 3/4( 2S -240)
S + S-240 + 3/4(2S-240) = 9800
Multiplie tout par 4 pour eliminer la fraction
4S + 4S -960 + 6S - 720 = 39200
14 S = 40.880
S = 2.920
P = 2.920-240 = 2.680
T =3/4(5.600) = 4.200
2.920 + 2.680 + 4.200 = 9.800

The sides of a rectangle are in a ratio of 7 : 4. If the perimeter of the rectangle is 176 ft, what is the area of the rectangle? The area of the rectangle is
Answers
Answer:
1792
Step-by-step explanation:
The sides of the rectangle is 7 and 4
7x, 4x
2(7x+4x) = 176
14x + 8x= 176
22x= 176
Divide both sides by the coefficient if x which is 22
x= 176/22
x= 8
7x
= 7(8)
= 56
4x
= 4(8)
= 32
Area of the rectangle
= 56×32
= 1792
The length of a trip varies directly as the amount of gasoline used. Yael's car used 16 L for the first 145 km of his trip from Toronto to Montreal. a) How much gasoline, rounded to the nearest litre, should he expect to use in the remaining 400 km of his trip? b) Can he complete the trip with a budget of $70, if gasoline costs $1.13/L?
Answers
Answer:
44
yes. the total cost is 68 which is less than 70
Step-by-step explanation:
There is positive proportionality is two variables are positively related to each other.
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
amount of gasoline = b x length of the trip
16 = b x 145
b = 16/145 = 0.110345
a. 400 x 0.110345 = 44
total litres used for the trip = 44 + 16 = 60
total cost of the trip = 60 x 1.13 = 67.8
total amount spent on gasoline is 67.8. this is less than the budget

The sound of a jet engine of a skyhawk jetfighter is 70000 times louder than the sound of a lawnmower if the lawnmower has the loudness of 88db then what is the loudness of the jet engine rounded to the 1DP
Answers
Answer: 6,160,000 db
Step-by-step explanation:
The sound of a jet engine is 70,000 times louder than that of a lawn mower.
Since we know the sound of a lawnmower, we can multiply that by 70,000 to find the sound of a jet engine:
= Sound of lawnmower * 70,000
= 88 * 70,000
= 6,160,000 db

A student has an average (arithmetic mean) score
of 86 points for 4 tests. What total score does this
student need in the next two tests in order to have
an average of 90 for all 6 tests?
Please help!! Thank you!
Answers
Answer:
90 & 96
Step-by-step explanation:
if you add them and mean them you will conclude this solution
The total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be 196.
What is Mean?The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.
A student has an average (arithmetic mean) score of 86 points for 4 tests.
The total number of 4 tests will be
→ 86 x 4
→ 344
Then the total score this student needs in the next two tests in order to have an average of 90 for all 6 tests will be
The total number of 6 tests will be
→ 6 x 90
→ 540
Then the score in the last 2 tests will be
→ 540 - 344
→ 196

|x-1|-1=1 what’s the value of x
Answers
Answer:
x=3, x=-1
Step-by-step explanation:
|x-1|-1=1
Add 1 to each side
|x-1|-1+1=1+1
|x-1|=2
Now set the absolute value to ±2
x-1 = 2 and x-1 = -2
Add 1 to all sides
x-1+1 = 2+1 x-1+1 = -2+1
x=3 x = -1
Step-by-step explanation:
|x - 1| - 1 = 1
Add 1 to each side
|x - 1| - 1 + 1 = 1 + 1
|x - 1| = 2
Now set the value to +_ 2
x - 1 = 2 and x - 1 = -2
Add 1 to all sides
x - 1 + 1 = 2 + 1 x - 1 + 1 = -2 + 1
x = 3 x = -1

So,
16x - 1 = 1/2(30x + 4) = 15x + 2
x - 1 = 2
x = 3
m∠SRT = 16(3) - 1 = 48 - 1 = 47
