Answer:
13/3
Step-by-step explanation:
3x + 2(4x − 6) = 8x + 1
3x + 8x - 12 = 8x + 1
11x - 12 = 8x + 1
3x - 12 = 1
3x = 13
x = 13/3

Answer:
17.98
Step-by-step explanation:
The sequence is geometric with first term a1 = 12 and common ratio r = 1/3. Put these numbers in the formula and do the arithmetic.
[tex]S_n=a_1\cdot\dfrac{1-r^n}{1-r}\\\\S_6=12\cdot\dfrac{1-\dfrac{1}{3^6}}{1-\dfrac{1}{3}}=12\cdot\dfrac{3}{2}\cdot\dfrac{728}{729}=\dfrac{1456}{81}\approx\boxed{17.98}[/tex]

Given:
ST || RU
To find:
The measure of QS.
Solution:
In triangle QRU and QST,
[tex]\angle RQU\cong \angle SQT[/tex] [Common angle]
[tex]\angle QRU\cong \angle QST[/tex] [Corresponding angle]
[tex]\triangle RQU\sim \triangle SQT[/tex] [AA property of similarity]
The corresponding sides of similar triangles are proportional.
[tex]\dfrac{QR}{QS}=\dfrac{QU}{QT}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{25+50}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{25}{75}[/tex]
[tex]\dfrac{23}{QS}=\dfrac{1}{3}[/tex]
On cross multiplication, we get
[tex]3(23)=1(QS)[/tex]
[tex]69=QS[/tex]
Therefore, the measure of QS is 69.
Selecting two marbles from a bag containing the numbers 2,4,6,8,10,12 (with replacement) what is the probability of selecting two numbers less than 10 ?
Given:
A bag containing the numbers 2,4,6,8,10,12.
To find:
The probability of selecting two numbers less than 10.
Solution:
We have,
Total numbers = 6
Numbers less than 10 are 2,4,6,8.
Numbers less than 10 = 4
Probability of getting a number less than 10 is:
[tex]P(\text{Less than 10})=\dfrac{\text{Numbers less than 10}}{\text{Total numbers}}[/tex]
[tex]P(\text{Less than 10})=\dfrac{4}{6}[/tex]
[tex]P(\text{Less than 10})=\dfrac{2}{3}[/tex]
We select the second number with replacement. So, the probability of second draw is same as the probability for first draw.
Probability of selecting two numbers less than 10 is:
[tex]\text{Required probability}=P(\text{Less than 10})\times P(\text{Less than 10})[/tex]
[tex]\text{Required probability}=\dfrac{2}{3}\times \dfrac{2}{3}[/tex]
[tex]\text{Required probability}=\dfrac{4}{9}[/tex]
Therefore, the probability of selecting two numbers less than 10 is [tex]\dfrac{4}{9}[/tex].

Answer:
Step-by-step explanation:
we know that the triangle to the center is an isosceles, so the two angle on the circle of that triangle are the same. both 41, so 41*2 =82
all the way around that isosceles triangle is 180 so
180-82 = 98
the angle at O is 98°
the arc BC spans 98°
angle 'a' is 1/2(98°)
a = 49°
Marsha likes to take photos with her new camera.She already has 1427 photos. She just bought her camera 15 days ago and took pictures everyday.Approximately how many pictures did she take each day?
Answer:
About 95
Step-by-step explanation:
If she bought her camera 15 days ago, then you just divide 1427 by 15. You can't take parts of pictures, so it has to be a whole number, so you round.
Answer:
95.1333333333 you should probably round it but thats how many photos she took each day
Step-by-step explanation:
1427/15= photos taken each day
in which groupthe given angels(160,20)will fall,if their sum is 180
Answer:
Supplementary angles.
Step-by-step explanation:
We can define two big groups of pairs of angles.
Complementary and supplementary angles.
Two angles are complementary if the sum of their measures is equal to 90°
Two angles are supplementary if the sum of their measures is equal to 180°
Here, we have the angles 160° and 20°, and we know that their sum is 180°
Then we can conclude that the given angles fall in the group of the supplementary angles.

write the slope-intercept form of the equation of the line through the given points.
Answer:
y = 4x - 7 (Answer C)
Step-by-step explanation:
First find the slope of this line. Note that as we go from (2, 1) to (3, 5), x (the 'run') increases by 1 and y (the 'rise') increases by 4.
Thus, the slope, m, is
m = rise / run = 4/1, or m = 4.
Apply the point-slope form of the equation of a straight line, since we now have both the slope and two points on the line:
y - k = m(x - h) becomes y - 1 = 4(x - 2)
Solving for y, we get: y = 4x - 8 + 1, or y = 4x - 7 (Answer C)
A = {prime numbers between 4 and 25} B = {odd numbers less than 16} List the outcomes of A, B and explain? List the outcomes of A, B and explain?
The image below better explains it. Thank you.
Answer:
A u B = {1,3,5,7,9,11,13,15,17,19,23}
A n B = {5,7,11,13}
Step-by-step explanation:
The prime numbers between 4 and 25 are; 5, 7, 11 , 13 , 17 , 19 and 23
A = {5, 7,11, 13, 17, 19,23}
B are odd numbers less than 16
B = {1, 3 , 5,7,9,11,13,15}
The union of both is the list of all values present in both sets without repeating;
A u B = {1, 3, 5,7,9,11,13,15,17,19,23}
A n B is the set that contains values that are present in both sets
A n B = {5,7,11 , 13}
Three consecutive integers add up to 51. What are these integers
Let the three consecutive integers be x, x+1 and x+2.

Goran has scored 38, 27, 23, 19, and 26 points in his five basketball games so far. How many points does he need to score in his next game so that his average (mean) is 27 points per game?
Answer:
29
Step-by-step explanation:
(38+27+23+19+26+X)/6=27
133 + X = 162
X = 29
Answer:
29
Step-by-step explanation:
The mean is calculated as
mean = [tex]\frac{sum}{count}[/tex]
let x be the score required to give a mean of 27 in the 6 games
[tex]\frac{38+27+23+19+26+x}{6}[/tex] = 27 ( multiply both sides by 6 )
133 + x = 162 ( subtract 133 from both sides )
x = 29
He requires to score 29 points

Answer:
First, we can find the least common denominator for 8 and 3 which is 24.
5/8 = 15/24
1/3 = 8/24
Then we can divide 15/24 by 8/24 which is 2 1/4.
If we then do 16 divided by 2 1/4 we get 7 1/9
Answer = 7 1/9

What is the surface area of a cylinder with a height of 20 meters and a diameter of 10 meters? O A) 1884 m2 OB) 863 m2 OC) 353.25 m2 OD) 785 m2
Answer:
785
Step-by-step explanation:
did the math in a calculator I got yoy
Answer:
D. 785
Step-by-step explanation:
the formula to find the surface area of a cylinder is A=2πrh+2πr^2
the diameter is a straight line through the center of a figure so half of that would be the radius and our diameter is 10 so the radius is 5
our height is 20 so now we put it into the equation it will look like this
2·π·5·20+2·π·5^2
once you do the math you will get 785.39816

Wendell is looking over some data regarding the strength, measured in Pascals (Pa), of some building materials and how the strength relates to the length. The data are represented by the exponential function f(x) = 2x, where x is the length. Explain how he can convert this equation to a logarithmic function when strength is 8 Pascals.
Step-by-step explanation:
f(x) = 2^x (this is exponential function)
f(x) = 8
the equation is :
2^x = 8
2^x = 2³
cross out 2
so, we get : x= 3
The conversion is given below.
x is 3.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = [tex]2^x[/tex]
f(x) = strength and x is the length.
Now,
Strength = 8
So,
8 = [tex]2^x[/tex]
Taking logs on both sides.
log 8 = x log 2
x = log 8 / log 2
x = log (8/2)
x = log 4
x = log [tex]2^2[/tex]
x = 2 log 2
or
2 x 2 x 2 = 2³ = 8
So,
8 = 2³
x = 3
Thus,
x = 3.

On the map below, 1 cam represents 50 km. The distance between sommerwile and Linden is 2.5 cm.
Answer:
125
Step-by-step explanation:
Answer: I think it's D
Step-by-step explanation: I say the answer is (B) because in the full question, it's asking how much would 2.5 means, therefore, you're multiplying, to get 125.
If 1cm=50km Then 2.5 is 50km, 50km, 25
50+50+25=125, or simply just multiply. 25 is half of 50, so with the 2.5 there, doesn't make it a whole number, therefore, making the 25 in it's place, because of the 2.5.
