Answer:
X = 10.588
Y = 28.2
Z = 21.176
Step-by-step explanation:
Consider Nova savings as X
Helga is Y
Maurice is Z
As per first ratio we conclude 8X=3Y
Second ratio we conclude 3Y = 4Z
We deduce 8X = 4Z
Last sentence => X+Y+Z=60 multiple it by 3
=> 3X + 3Y + 3Z= 180 but 8X = 4Y
=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3
44/3 X + 4Z = 240 but 4Z = 8X
=> 44/3 X + 8 X = 240
=> 68/3 X = 240
=> 68X = 720
=> X =10.588
And Y=8/3 X =28.2
And Z=3/4 Y = 21.176

Hey!
So what it's asking for is the slope of the line. You can figure this out by finding two solid points on the line, such as (0,-1) and (4,2).
Knowing that these are two solid points, you can use the Rise/Run method to get the answer. The rise is how many units the slope rises (+) or falls (-) when getting to the next point. The run is how many units to the left or right it goes.
By following this, the slope is 3/4
jo jo has a total amount of $12.45 in quarters and dimes in his pocket. he has a total of 60 coins. how many quarters and dimes does jo jo have?
a. 42 quarters and 18 dimes b. 43 quarters and 17 dimes
c. 44 quarters and 16 dimes d. 41 quarters and 19 dimes
e. 40 quarters and 20 dimes
NEED ANSWERED ASAPP!!!
Given:
Total number of coins (Quarters and dimes) = 60
Total amount = $12.45
To find:
The number of quarters and dimes.
Solution:
Let x be the number of quarters and y be the number of dimes.
We know that,
1 quarter = 0.25 dollar
1 dime = 0.10 dollar
Total coins: [tex]x+y=60[/tex] ...(i)
Total amount: [tex]0.25x+0.10y=12.45[/tex] ...(ii)
From (i), we get
[tex]y=60-x[/tex] ...(iii)
Putting this value in (ii), we get
[tex]0.25x+0.10(60-x)=12.45[/tex]
[tex]0.25x+6-0.10x=12.45[/tex]
[tex]0.25x-0.10x=12.45-6[/tex]
[tex]0.15x=6.45[/tex]
Divide both sides by 0.15.
[tex]x=\dfrac{6.45}{0.15}[/tex]
[tex]x=43[/tex]
Putting x=43 in (iii), we get
[tex]y=60-43[/tex]
[tex]y=17[/tex]
So, the number of quarters is 43 and the number of dimes is 17.
Therefore, the correct option is b.

Find the value of the sine for angle A
Answer:
B
Step-by-step explanation:
sin=opposite/Hypotonouse
80²+60²=hyp²
hyp=100
sinФ=60/100=3/5
Answer:
b. 3/5
Step-by-step explanation:
Using the pythagorean theorem, side AB is 100 m long.
Sine equals opposite over hypotenuse. In this case CB (60) is the opposite and AB (100) is the hypotenuse.
Sine for angle A = 60/100 = 3/5

MIguel is making a trail mix. He Uses five and one third ounces of nuts and two and tree fourths ounces of raisins Which of these is a reasonable estimate for how much more nuts Miguel uses than raisins?
(Keep as a fraction and don’t change to decimal please)
Answer:
[tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins
Step-by-step explanation:
The computation is shown below:
Nuts used [tex]= 5 \frac{1}{3} = \frac{16}{3}[/tex]
Raisins used [tex]= 2 \frac{3}{4} = \frac{11}{4}[/tex]
Now the difference between them is
[tex]= \frac{16}{3} - \frac{11}{4}\\\\= \frac{64 - 33}{12} \\\\= \frac{31}{12}[/tex]
Hence, [tex]\frac{31}{12}[/tex] more nuts would be used by Miguel then raisins
- Write 4/12 as a sum of unit fractions
Answer:
Step-by-step explanation:

Answer:
5
Step-by-step explanation:
You want me to let you in on a secret? There's a simple equation that you can use to solve any quadratic problem in a minute or two.
It's the quadratic formula
x = [tex]x = \frac{-b +- \sqrt{b^2 - 4ac} }{2a}[/tex]
The +- means that you will do this two times, the first time you will do -b + sqrt(b^2-4ac), and the second time you will do minus that.
a is the coefficient of the first term in the expression, b is the second and c is the third.
so we get[tex]x = \frac{-(-10) +- \sqrt{(-10)^2 - 4(1)(24)} }{2(1)}[/tex] , which is the same as
[tex]x = \frac{10 + \sqrt{100 - 24(4)} }{2}[/tex]
and
x = [tex]x = \frac{10 - \sqrt{100 - 24(4)} }{2}[/tex]
The top part simplifies to [tex]\frac{10 + \sqrt{100 - 72} }{2} = \frac{10 + 6}{2} = 5[/tex], which is your answer.
