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:
77 degrees
Step-by-step explanation:
The angles of a triangle must add up to 180 degrees
61+42=103
180-103=77
Answer:
77
Step-by-step explanation:
I always add up the other two and since the total degrees of a triangle has to add up to 180 I subtract the sum so
61+42=103
180 - 103 = 77

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)
Find the solution set of the inequality
4x-1< 11.
PLEASE HEP I NEED THIS ASAP!!!!
Answer: x > 3
Step-by-step explanation:
In order to find x, we must isolate it first.
Add one to both sides. It's now 4x < 12.
Now we divide both sides by 4, remember that every time we divide or multiply we must flip the inequality symbol.
The final answer is x > 3

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°

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}
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.

find the value of z of the equation 2z=5(8-z)
Hey Mate,
Given,
z - 2z/3 + z/2 = 5
Then, On taking the LCM of 1, 2 and 3 as we get 6, the new equation will be :-
=> = 5
=> = 5
=> 5z = 5 x 6
=> z = 30/5
=> z = 6
Therefore, z = 6 is the root of the equation z - 2z/3 + z/2 = 5.
Now on substituting the value of z as 6 in the given equation, we get:-
( 6 ) - 2(6)/3 + ( 6 )/2 = 5
6 - 12/3 + 3 = 5
6 - 4 + 3 = 5
2 + 3 = 5
5 = 5
Since, LHS = RHS, z = 6 is the correct root for the equation :-
z - 2z/3 + z/2 = 5
Hope it Helps!

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

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.

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

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.
