Answer:
bro answer is 9
Step-by-step explanation:
i took test
6x – 9 = 33 Check
please and thank you
Answer:
x = 7
Step-by-step explanation:
6x - 9 = 33
6x = 33 + 9
6x = 42
x = 42 / 6
x = 7
6x - 9 = 33
6 x 7 - 9 = 33
42 - 9 = 33
33 = 33
Hope that helps!
Answer: x=7
Step-by-step explanation:
6x-9=33
for x
6x=33+9
6x=42
x=42/6
x=7
for checking put value of x
6*7-9=33
42-9=33
33=33

Answer:
the mean is 9
Step-by-step explanation:
add all the numbers then divide by 6
Answer:
The mean is 9.
Step-by-step explanation:
The mean of a data set is all of the numbers added together, divided by how many numbers are present.
For instance, 10+10+8+9+7+10 = 54.
Since there are 6 numbers in this data set, you divide 54 by 6 and get 9.
Therefore, the mean of this data set is 9.

Given that sec0=-37/12, what is the value of cot0, for pi/2<0
Answer:
2nd option
Step-by-step explanation:
Using the identities
tan²θ + 1 = sec²θ
cotθ = [tex]\frac{1}{tan0}[/tex]
Given
secθ = - [tex]\frac{37}{12}[/tex] , then
tan²θ + 1 = (- [tex]\frac{37}{12}[/tex] )² = [tex]\frac{1369}{144}[/tex] ( subtract 1 from both sides )
tan²θ = [tex]\frac{1225}{144}[/tex] ( take the square root of both sides )
Since [tex]\frac{\pi }{2}[/tex] < θ < π and tanθ < 0 , then
tanθ = - [tex]\frac{35}{12}[/tex]
Then
cotθ = [tex]\frac{1}{-\frac{35}{12} }[/tex] = - [tex]\frac{12}{35}[/tex]

B - p (t) = 25,000 (.099)^t
C - p (t) = 25,000 (0.99)^t

Quadrilateral A B C D is the image of a quadrilateral ABCD under a rotation about point P
Determine the angle of the rotation
-105
-75
75
105
Answer:
D. 105°Step-by-step explanation:
If we connect points C and C' with the center of rotation P, the angle CPC' appears greater than 90°, so the angle could be 105° or - 105°
Since the rotation is counterclockwise the angle of rotation is deemed as positive.
Correct choice is D.

An aquarium holds 11.95 cubic feet of water, and is 2.8 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
3.05feet
Step-by-step explanation:
Given data
Volume = 11.95 cubic feet
Lenght = 2.8 feet
Width= 1.4feet
Depth= ????
We know that the expression for the volume is
V= L*W*D
substitute
11.95= 2.8*1.4*D
11.95= 3.92D
divide both sides by 3.92
D= 11.95/3.92
D= 3.05
Hence the depth is 3.05feet approx

In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°
Answer:
14.2cm
Step-by-step explanation:
Complete question:
In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.
Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?
Find the diagram attached
arc LN= arc LM + arc MN
First we need to get the arc MN
length of an arc = theta/360 * 2πr
length of arc MN = 75/360 * 2(3.14)(6)
length of arc MN = 0.20833*37.68
length of arc MN = 7.85
Hence;
arc LN = 6.3 + 7.85
arc LN = 14.15cm
Hence the length of arc LN is 14.2cm
A circle is centered at the point (-7,-1) and passes through the point (8, 7). The radius of the circle is ___ units. The point (-15, __ ) lies on this circle
Answer:
(x + 7)2 + (y + 1)2 = r2.
To get we use point (8, 7): (8 + 7)2 + (7 + 1)2 = r2, r2 = 225 + 64 = 289 = 172.
So, equation of circle: (x + 7)2 + (y + 1)2 = 289

Diego props a 10ft ladder against the wall how high up will the ladder reach if the foot of ladder is 5 feet away from the wall ?
Answer:
5√3 ft
Step-by-step explanation:
If the ladder is 10ft tall, then that represents the hypotenuse. If the foot of our ladder is 5ft away from the wall, that is a side length that we know. Using the Pythagorean Theorem, a²+b²=c², where a and b are side lengths of a right triangle, and c is the hypotenuse, we can solve for the missing side length:
a²+b²=c²
(5)²+b²=(10)²
25+b²=100
b²=75
b=√75
b=5√3
So the ladder will reach a height of 5√3 ft.
helo me please please
i) Area = length x width
=250 x 100
= 25000 cm2
ii) it is a square so the sides are equal
Area = 10 x 10
= 100cm2
iii) 25000/100
