Answer:
n = 12.546
Step-by-step explanation:
to find the value of n we need to transpose
n ÷ 102 = 0.123
n = 0.123 × 102
n = 12.546
Given that f(x) = 5(7)*, find f(4)
How to calculate the distance between two runners?? Ex) A finish 100m in 10.93 sec, and B finish in 10.49 sec, by how many meters did B won?? (Pls help me)
Answer:
The average speed of A is
100m ÷ 10. 93s = 9.14m/s
The average speed of B is
100m ÷ 10. 49s = 9. 53m/s
The average speed that B is faster than A is 9. 53 - 9. 14 = 0. 42m/s
The speed that B is faster than A is
0. 42m/s × 10. 49s = 4. 40m
So, B won by 4. 40m

−5x+4y=3
x=2y−15
what would be the values of x and y
Answer:
x=9 y=12
Step-by-step explanation:
eqn 1 - x=2y-15
eqn 2- -5x+4y=3
-5(2y-15)+4y=3
-10y+75+4y-3=0
-6y+72=0
y= 12
x=2y-15
x=2(12)-15
x= 9

PLEASE HELP ME ITS SO CONFUSING
Answer:
Step-by-step explanation:
The first thing should always do is find a program that will show you what the graph looks like. Desmos is a free program that suits all graphing questions.
That will give you the answer (which I have labeled for you.)
First make x = 0
That gives you y = 0 + 4 = 4
The point is (0,4)
Now let y = 0
0 = -1/5 x + 4 Add 1/5x to both sides
1/5 x = 4 Now multiply by 5
x = 5*4
x = 20
The point is (20,0)
You need one more point just to confirm your work. I chose x = - 5
When you do the calculation it comes out to y = 5
The point is (-5,5) which is labeled.
Kim is making cookies. She is using a recipe that calls for 1/4 cup of lemon juice. She has a 6 fl oz. bottle of lemon juice. There are 8 fl oz. of lemon juice in 1 cup. How many batches of cookies can she make?
Answer:
3
Step-by-step explanation:
Answer:
Step-by-step explanation:
1 cup = 8 fl oz
x cup = 6 fl oz Cross multiply
6 oz * 1 cup = 8 oz x divide by 8
x = 6 oz /8 oz = 3/4 cup
If kim needs 1/4 cup per batch then she will have enough for 3 batches of 1/4 cup each.
4 The equation 5W + 3 = 4w + 9 is modeled below. w W 1 W W 1 1 W 1 1 W W 1 1 1 What value of w makes this equation true? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value. MI - SI – PSA- S-
Answer:
w = 6.
Step-by-step explanation:
5w + 3 = 4w + 9
5w - 4w = 9 - 3
w = 6
Then, check your work!
5(6) + 3 = 4(6) + 9
30 + 3 = 24 + 9
33 = 33
So, w = 6 will be the correct answer.
Hope this helps!

Answer:
see explanation
Step-by-step explanation:
Complementary angles sum to 90° , then
5x + 7 + 8x - 21 = 90 , that is
13x - 14 = 90 ( add 14 to both sides )
13x = 104 ( divide both sides by 13 )
x = 8
Then the measure of the angles are
5x + 7 = 5(8) + 7 = 40 + 7 = 47°
8x - 21 = 8(8) - 21 = 64 - 21 = 43°
--------------------------------------------------------
let the angle be x then its complement is (90 - x) and
x = 2(90 - x) + 21
x = 180 - 2x + 21
x = 201 - 2x ( add 2x to both sides )
3x = 201 ( divide both sides by 3 )
x = 67
The measure of the angle is 67°
What is (f - g)(x)? f(x) = 3x g(x) = -3x² + 3x Write your answer as a polynomial or a rational function in simplest form.
Answer:
3x²
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
= 3x - (- 3x² + 3x) ← distribute parenthesis by - 1
= 3x + 3x² - 3x ← collect like terms
= 3x²

find the smallest number that should be multiplied to 3993 to make it perfect cube
[tex]cube \: and \: cube \: root \: [/tex]
Answer:
First, let us prime factorise the given number
3993 = 3×11×11×11
Check for numbers in triplets. We find that only 11 is occuring as a triplet. Hence we must eliminate the three.
So if we divide 3993 by 3, we'll get a perfect cube, that is 1331 (11³)
So, the answer is 3

cos5xcosx-sin5xsinx=??????????????????
Answer:
cos6x.

so cos5xcosx - sin5xsinx = cos(5x + x)
= cos6x.
At a competition with 7 runners, medals are awarded for first, second, and
third places. Each of the 3 medals is different. How many ways are there to
award the medals?
Decide if this is a permutation or a combination, and find the number of ways
to award the medals.
Answer:
35 different combinations
Step-by-step explanation:
This would be a combination because the same person cannot get all three medals so permutation is not the correct way to calculate this. We use the formula C(n,r)=(nr)=n!(r!(n−r)!)=? where n is the number of total objects and r is the number of objects taken from the total.

y=x^2-2x-5 vertex form
Hey there! I'm happy to help!
First, we'll want to find the vertex of this parabola.
Given the equation y=ax^2+bx+c, the formula for the x-coordinate of the vertex is always [tex]-\frac{b}{2a}[/tex].
In our equation here, our a is 1 and our b is -2.
[tex]-\frac{-2}{2}=\frac{2}{2}=1[/tex]
Now that we have our x-value of our vertex, we can plug it into our equation to find our y-coordinate.
y=1²-2(1)-5
y=1-2+5
y=-1+5
y=4
So, our vertex is at (1,4).
Vertex form is y=a(x-h)²+ k where (h,k) is our vertex. We know now that our vertex is (1,4) and we also know that our a is 1, so we can simply plug it in to this equation.
y=(x-1)²+4

Vie sold 45 raffle ticket. his brother sold twice as many. How many tickets did the sell together?
Answer:
135 tickets
Step-by-step explanation:
Vie's brother sold twice as many as Vie. So we multiply Vie's tickets by 2 to get the brother's.
VIe's brother sold 45 * 2 = 90 tickets
And all together the two sold
45 + 90 = 135 tickets
