Marlon is bowling in a tournament and has the highest average after 5 games, with scores of 210, 225, 254, 231, and 280. In order to maintain this exact average, what must be Marlon’s score for his 6th game?
Answer:
240
Step-by-step explanation:
Right now, Marlon's average is (210 + 225 + 254 + 231 + 280) / 5 = 240. To maintain that average, the sum of Marlon's scores after 6 games must be 240 * 6. Currently, the sum of Marlon's scores is 240 * 5 so he must score a 240 * 6 - 240 * 5 = 240(6 - 5) = 240 * 1 = 240 for his last game.

Two people share $52.20 in the ratio 4:5. How much does each person receive?
Answer:
$23.20 and $29
Step-by-step explanation:
We can set up a simple equation to solve this problem.
4x + 5x = 52.2
9x = 52.2
x = 5.8
To find out how much each person received, we multiply 5.8 with the ratio numbers 4 and 5. That gives us $23.20 and $29, respectively.

HELP! Determine the equation of the exponential function with a common ratio of 2, a horizontal asymptote at y = 4, and passing through the point (2, 10).
Answer:
[tex]\bold{y=1.5\times 2^x+4}[/tex]
Step-by-step explanation:
Equation for an exponential function is given as following:
[tex]y=ab^x+c[/tex]
Where b is the common ratio and
c is the horizontal asymptote (y value)
a is the coefficient of exponential term of [tex]x[/tex]
[tex](x,y)[/tex] are the points on the function.
Here, we are given that:
Common ratio, b = 2
Horizontal asymptote at y, c = 4
So, the equation becomes (let us put the values of b and c):
[tex]y=a\times 2^x+4[/tex]
We need the value of a. Let us put value of (x,y) as (2,10).
[tex]10=a\times 2^2+4\\\Rightarrow a\times 4 =10-4 =6\\\Rightarrow a =\dfrac{6}{4} =\bold{1.5}[/tex]
So, the final equation of the exponential function is:
[tex]\bold{y=1.5\times 2^x+4}[/tex]
compressed by a factor
of 1/2, horizontally and
vertically translated 5 units
can someone help me find the equation
Should 21st century skills such as critical thinking, collaboration or logic and reasoning be taught in math class? Explain your answer.
Answer:
YES
Step-by-step explanation:
I would recomend them as electives, for students who want a higher level of education, not a required course. I do think school should offer more course options at there school, to specialize a students learning exsperience. So yes I think schools should offer these courses...as electives.
Answer:
No because that's not math related, it should be taught in/as a different class.
The points S, T, U and V all lie on the same line segment, in that order, such that the
ratio of ST : TU: UV is equal to 6:2:3. If SV = 22, find TV.
==============================================
Explanation
Let x be some positive real number such that
ST = 6xTU = 2xUV = 3xleading to the ratio
ST:TU:UV = 6x:2x:3x = 6:2:3
Note how I effectively started with 6:2:3 and multiplied all parts of the ratio by x to get 6x:2x:3x
-----------------
The parts of the ratio add up to the longest segment SV
ST+TU+UV = SV
6x+2x+3x = 22
11x = 22
x = 22/11
x = 2
Therefore,
ST = 6x = 6*2 = 12TU = 2x = 2*2 = 4UV = 3x = 3*2 = 6Note how ST+TU+UV = 12+4+6 = 22, which is the length of SV. This helps confirm we have the correct x value.
-----------------
The last step is to find the length of TV
TV = TU+UV
TV = 4+6
TV = 10
Or you could do
ST + TV = SV
12+TV = 22
TV = 22-12
TV = 10

4x - y = -7
-8x + 4y = 12
Elimination
Answer:
(x,y)=(-2,-1)
Step-by-step explanation:
4x - y = -7: 8x-2y=-14
8x-2y=-14
-8x + 4y = 12
add these two:
2y=-2
y=-1
plug in the y:
-8x-4=12
-8x=16
x=-2

What information do you need to complete a translation?
Answer:
1. The coordinates of the image you want to transform
2. The change in y
3. The change in x
Step-by-step explanation:
If we transform an image, we are moving it around the coordinate plane.
In order to transform, we need the original coordinates of the image so that we know where to start.
We also need to know the change in y because when we transform a shape it can go up and down.
We also need to know the change in x because when we transform a shape it can go left and right.

hi help me (2·4)²= this is other (6:2)²+
Answer:
(2·4)² = 64 / (6*2)² = 144
Step-by-step explanation:
Follow PEMDAS :
Parenthesis first, so:
2 * 4
==> 8
Then Exponent:
8 ^2
==> 64
(2·4)² = 64
Do the same for (6:2)² :
Parenthesis first :
6 * 2
==> 12
Then Exponent:
12^2
==> 144
(6:2)² = 144
Answer:
1. 64 is the answer.2. 144 is the answerStep-by-step explanation:
First, multiply the numbers inside the parenthesis. So
1. 2*4 = 8
2. 6*2 = 12
Next, Use the exponents
1. 8^2
2. 12^2
Finally, solve using exponents.
1. 8^2 = 64
2. 12^2 = 144
So 64 and 144 is the answer.

Answer:y=28
Step-by-step explanation:
all triangles add up to 180 and this triangle is an isosceles triangle so 34 should be equal to x-5 meaning that two of the angles are 34 degrees and you just need to subtract 34(2) from 180 which is 180-68 to give you 112. Then since this is the value of 4 times y, just divide 112 by four to isolate the variable and you get 28.
Trigonometry help? Please answer 4.5,6 for me if u can! Tysm
Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
