Ryan has scores 32, 26, and 23 points in his four basketball games so far. How many points does he need to score in his next game so that his average (mean) is 26 points per game?
Answer:
23
Step-by-step explanation:
Ryan needs to score a 23 this game because if you add all the numbers together (32 + 26 + 23 + 23) then divide them
(32 + 26 + 23 + 23)/4
You will get 23.
Answer:
23 points
Step-by-step explanation:
Let's first start out by first finding the current mean. We can find this by:
[tex]\frac{32+26+23}{4}=27.[/tex]
So we know that his current average is 27 points per game, and we need the average to be 26. So, to find out the total number of points he scores from his 1st, 2nd, 3rd, and 4th game, we will do:
[tex]26\cdot4=104[/tex]
So if he needs 104 points in total to have an average of 26. So, we would subtract his total number of points from his 1st, 2nd, and 3rd game, from 104. If we do this, we would get:
[tex]104-(32+26+23)=104-81=23[/tex]
So he would need to score 23 points next game to have an average of 26 points.

Your classmates Sarah, Gene and Paul are proposing plans for a class fundraiser. Each presents his or her proposal for the amount of money raised, y, for x number of hours worked, in different ways.
Answer:
yx
Step-by-step explanation:
The answer is yx
We can draw the conclusion that linear functions can be used to represent each of the ideas. Due to the fact that each proposal's linear function has an initial value, the class now has money in its accounts (b).
What is "Linear Function" ?A linear function is denoted by the equation y = mx + b, where m is the slope or unit rate between the two variables, x and y, and b is the beginning value or y-intercept.
The initial value is b.
A linear function is a graph with straight lines.
A unit rate exists for all linear functions (b).
here, we have,
given that,
Sarah's suggestion can be expressed by a linear function because the graph that represents it is a straight line.
Gene's Proposal's table displays the unit rate as change in y/change in x = 7. As a result, a linear function can be used to express it.
Paul's idea has a linear function as its equation.
This leads us to the conclusion that linear functions can be used to represent each of the ideas.
Due to the fact that each proposal's linear function has an initial value, the class now has money in its accounts (b).

Find the value of x. Then find the measure of each interior angle. Show work algebraically
Answer:
Step-by-step explanation:
W=180-144
W=36 degrees
The sum of angles in a triangle always sum to 180 degrees.
6x+1+7x+36=180
13x+37=180
13x=143
x=11
U=6x+1
U=6(11)+1=67 degrees
V=7x
V=7(11)=77 degrees so
x=11 degrees, U=67 degrees, V=77 degrees, and W=36 degrees.

Answer:
angle B = 66.42
Step-by-step explanation:
cos-1 B = [tex]\frac{adjacent}{hypotenuse}[/tex]
cos-1 B = [tex]\frac{2}{5}[/tex]
cos-1 B = 0.40
cos-1 of 0.40 is 66.4218

Tim is 5 pounds heavier than Amy. Let Amy's weight will be x pounds
A) Express Tim's weight in terms of x
b) if Tim's weight is 126 pounds, what is Amy's weight?
(show you work)
Answer:
A) x+5
B) 121
Step-by-step explanation:
A) If Tim is 5 pounds heavier than Amy, an equation for this situation can be modeled by x+5, where Amy is x pounds.
B) If Tim is 126 pounds, then Amy's weight is 126-5=121 pounds.

Write the equation for each table
Answer:
Step-by-step explanation:
First table:(left)
(1, 15) (2, 30)
(30 - 15)/(2 - 1) = 15/1 = 15
y - 15 = 15(x - 1)
y - 15 = 15x - 15
y = 15x
Second table:(right)
(0, 10) (1, 25)
(25 - 10)/(1 - 0)= 15/1= 15
y - 10 = 15(x - 0)
y - 10 = 15x - 0
y = 15x + 10
y = 4x + 6 ; 5x + y = -21
Answer:
=4x + 5x ;6 + (-21)
=9x -15
= -6x

this cuboid is made from cm squares
a)write down the volume of the cuboid
b)the cuboid is then split apart into these smaller cuboids. how many of these can be made?
Answer:
Step-by-step explanation:
Each signal unit cubes are 1 cm to each side
the dimensions of the large cube is 4 by 6 by 3 width height and depth
a) volume of the cube Vol = area of the base times height
area of the base = the width times the depth
Volume = Base Depth
= Width x Depth x Height
= 4 x 3 x 6
= 12 x 6
Vol = 72 cm ³
b ) the volume of the smaller cuboid has different dimensions
the smaller cube is 2 by 2 by 1 width height and depth
Volume = Base Depth
= Width x Depth x Heigh
= 2 x 2 x 1
Vol smaller cuboid = 4
How many smaller cubes can be made?
The obvious answer might be to straight up divide the large cube volume by the smaler cuboid volume. That might work IF all of the cuboid dimensions divide evenly into the cube dimensions.
Number of cuboid = Volume of the cube / Volume of the cuboid
= 72 / 4
= 18
Check this answer by dividing the dimension of the cube by the cuboid
4 by 6 by 3
2 by 2 by 1
(4/2) by (6/2) by (3/1)
2 by 3 by 3 = 2 x 3 x 3 = 18

if x varies directly as y, and y=6 when x=27, find x when y=2
Answer:
x = 9
Step-by-step explanation:
Given y varies directly as y then the equation relating them is
x = ky ← k is the constant of variation
To find k use the condition y = 6 when x = 27
27 = 6k ( divide both sides by 6 )
4.5 = k
x = 4.5y ← equation of variation
When y = 2 , then
x = 4.5 × 2 = 9
