minutes?
Answer:
Time measure: 8 miles = 30 seconds We are given 45 minutes × 60 seconds /30= 90 miles8 divided by 1 4/5 in either fraction form or just number
Answer:
4.44444444444 or 40/9
Step-by-step explanation:
i searched it up
8 divided by 1 4/5 in fraction form will be 40 / 9. Then the faction number 40 / 9 in the decimal form will be 4.4444.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The mixed fraction number is converted into a faction number.
⇒ 1 4/5
⇒ 1 + 4/5
⇒ (5 + 4) / 5
⇒ 9/5
Then the quotient of the numbers 8 and 9/5 will be given as,
⇒ 8 / (9/5)
⇒ 8 x 5 / 9
⇒ 40 / 9
The faction number 40 / 9 in the decimal form will be 4.4444.

The equation of the line?
Answer:
○ [tex]\displaystyle y = 2x + 7[/tex]
Step-by-step explanation:
Use the Slope-Intercept Formula instead of the Point-Slope Formula because it is MUCH, MUCH faster, plus parallel equations have SIMILAR RATE OF CHANGES [SLOPES ], so [tex]\displaystyle 2[/tex] remains as is:
[tex]\displaystyle y =mx + b \\ \\ 3 = 2[-2] + b → 3 = -4 + b; 7 = b \\ \\ \boxed{y = 2x + 7}[/tex]

Jayla paints a book case. She uses 1 5/6 cups of paint on the outside of the book case and 3/8 cup of paint on the inside. How many cups of paint does Jayla use altogether
Answer:
Answer: Kayla used 2&5/24 cups of paint all together.
Step-by-step explanation:
Kayla paints a bookcase by using
1 5/6 cups of paint on the outside of the bookcase. Converting 1 5/6 cups to improper fraction, it becomes 11/6 cups of paint.
She also used 3/8 cup of paint on the inside.
Therefore, the total number of cups of paint that Kayla used all together would be cups of paint:
[tex]11/6 + 3/8 = (44 + 9)/24 = 53/24[/tex]
Converting to mixed fraction, it becomes
2 and 5/24 cups of paint

A puzzle has 80 pieces. Carlos has completed 60% of the puzzle. How many pieces of the puzzle has he put together?
Step-by-step explanation:
100% of the puzzle = 80 pieces
60% of the puzzle = 80 * (60/100) = 48 pieces.
Therefore Carlos has put 48 pieces together.
I think of two consecutive odd numbers, five times the smaller plus three times the larger is 62. Find the numbers.
Answer:
7 and 9
Step-by-step explanation:
Variables:
x = smaller number
y = larger number
We can set up two equations with the information given:
5x + 3y = 62
and
y = x + 2
We get the second equation with the information that the two numbers are consecutive and both odd. therefore the smaller number is two less than the larger number, and the larger number is two greater than the smaller number.
Next, we need to replace our y in the first equation with the y in the second:
5x + 3y = 62
5x + 3 (x+2) = 62
5x + 3x + 6 = 62
8x = 56
x (smaller number) = 7
Finally, we solve for the larger number by placing it back into the second equation:
y = x + 2
y = 7 + 2
y (larger number) = 9

if cos x = 2 sin x, so the value of sin x cos x is ...
Answer:
1/2
Step-by-step explanation:
As cosx= 2sinx,
now,
so, sinxcosx = sinx(2sinx) = 2 sin²x
Again,
2sin²x =1
sin²x= 1/2
sinx = 1/ root 2
sinx = sin 30
x = 30

Sand falls onto a conical pile at the rate of 10 cubic feet per minute. The radius of the pile is always equal to one half it altitude. How fast is the altitude of the pile increasing when the pile is 5 feet high?
Answer:
Either one of these.
Step-by-step explanation:
volumepile=1/3 (PI r^2)h
but r=h/2, so
volume=1/12 PI h^3
dv/dt=10 ft^3/min
but dv/dt=1/12 PI 3h^2 dh/dt
solve for dh/dt
This assumes you mean by "altitude" the height. If you mean altitude as slant height, you have to adjust the fromula
_______________________________________________
given: r = h/2
V = (1/3)π r^2 h
= (1/3)π (h/2)^2 (h)
= (1/12) π h^3
dV/dt = (1/4)π h^2 dh/dt
for the given data ...
10 = (1/4)π(25)dh/dt
dh/dt = 10(4)/((25π) = 1.6/π feet/min
find a fraction equivalent to 1/2

my first expression answer is y=5 -2x How do I plug it into x-y=1 ?? The Y
1. x-5-2x=1 OR
2. x+5-2x=1
Answer:
All you need to do is make sure the first expression is solved for y (which it is), and then substitute it into the second expression in place of any occurrences of y:
given the second expression:
x - y = 1
We'll replace y with it's value in the first expression:
x - (y) = 1
x - (5 - 2x) = 1
Now we can expand the resulting equation:
x - 5 + 2x = 1
So neither of the answers provided are correct.
You can then solve for x:
x - 5 + 2x = 1
x - 5 + 5 + 2x = 1 + 5
x + 2x = 6
3x = 6
3x/3 = 6/3
x = 2
After that, you can find y by plugging x into either of the two original equations:
y = 5 - 2x
y = 5 - 2(2)
y = 5 - 4
y = 1

Answer:
g(3) = 0
Step-by-step explanation:
You know g(x) = 3x - 9. So, to find g(3), you have to replace x by 3 on the other side.
g(3) = 3(3) - 9
You can solve this.
g(3) = 9 - 9
g(3) = 0

we know that 25 × 3 = 75
- 2 √3 + √75
= -2 √3 + [tex]\sqrt{25 X 3}[/tex]
By using
[tex]\sqrt{ab} = \sqrt{a} \sqrt{b}[/tex]
= [tex]-2\sqrt{3} + \sqrt{25} X \sqrt{3}[/tex]

Which statement about the graph of y= 3x+5 is correct?
a. The line passes through the ordered pair (3, 0) and has a slope of 5.
b. The line passes through the ordered pair (0,5) and has a slope of 3.
c. The line passes through the ordered pair (5,20) and has a slope of 5/3
d. The line passes through the ordered pair (3, 14) and has a slope of 3/5
Answer:
b. The line passes through the ordered pair (0,5) and has a slope of 3.
Step-by-step explanation:
The equation given is in slope-intercept form.
[tex]y= mx+b[/tex]
m = slope
b = y-intercept
The slope is 3 in the equation. 3 is in m's spot.
[tex]y=\boxed{m}x+b\\\\y=\boxed{3}x+b[/tex]
The y-intercept is 5. This means that the line will pass through (0,5).
[tex]y=mx+\boxed{b}\\\\y=3x+\boxed{5}[/tex]
The correct option should be B.
Hope this helps.
