Answer:
x = 0.15
Step-by-step explanation:
We have two equivalent ratios: 0.5 (or 1/2)/x = 2/0.6. It looks like our Giant One is 4/4, since 0.5 * 4 = 2. We can divide 0.6 by 4 to find the value of x. 0.6/4 = 0.15, so x = 0.15.

Answer:
Angle 4 and angle 5 also equal 180
Because angles 4 and 5 are supplementary angles (two angles that add to 180) and because 4 and 5 equal 180 that means that 5 equals 6. So 5 and 6 are congruence angels

Find the number of ordered pairs (m,n) which satisfy the system
4(m - n) &= 7(1 - n),
3/2n= 4-2m.
If there are infinitely many such pairs, enter the word infinite.
There are no solutions to this system.
==========================================================
Explanation:
Let's simplify and rearrange terms for the first equation. The goal is to get it into the form Am+Bn = C, where A,B,C are constants.
4(m-n) = 7(1-n)
4m-4n = 7-7n
4m-4n+7n = 7
4m+3n = 7
Let's do the same for the second equation
(3/2)n = 4 - 2m
3n = 2(4-2m)
3n = 8 - 4m
4m+3n = 8
------------------------
The result of each simplification is that we ended up with 4m+3n on the left hand side for each equation. The only difference is that we got 7 for the first equation and 8 for the next one.
This is a contradiction because 4m+3n can only equal one number at a time for any given (m,n) pair. It's like saying z = 7 and z = 8 at the same time, where z = 4m+3n. But z can only equal one value at a time.
-------------------------
In summary, the given system leads to a contradiction and the system is inconsistent. This means that there are no solutions. There are 0 ordered pairs (m,n) that make both original equations to be true.
The correct answer is there is exactly one ordered pair ([tex]m = \dfrac{73}{56}[/tex] , [tex]n = \dfrac{13}{14}[/tex] ) that satisfies the given system of equations.
Given
[tex]4(m - n) = 7(1 - n)[/tex]
[tex]\dfrac{3}{2} n = 4 - 2m[/tex]
First, simplify the second equation:
[tex]\dfrac{3}{2} n +2m = 4[/tex]
Now, solve this equation for n:
[tex]n = (4 - 2m) * \dfrac{2}{3}[/tex]
[tex]n = \dfrac{(8 - 4m)}{3}[/tex]
Now, substitute this value of n into the equation [tex]4(m - n) = 7(1 - n)[/tex] :
[tex]4(m - \dfrac{(8 - 4m)}{3}) = 7(1 - \dfrac{(8 - 4m)}{3}[/tex]
[tex]m = \dfrac{73}{56}[/tex]
From the value of m, substitute it back into the equation for n:
[tex]n = \dfrac{(8 - 4m)} { 3}[/tex]
[tex]n = \dfrac{13}{14}[/tex]
The solution is one ordered pair [tex]m = \dfrac{73}{56}[/tex] and [tex]n = \dfrac{13}{14}[/tex].

Padma cycles 3 1/4 miles. Josh cycles 7/2 miles. How far have they cycled in total? Give your answer as a mixed number. show your working.
Answer: 6 3/4 miles
Explanation: turn 3 1/4 into an improper fraction makeing it 13/4 multiply both 7 and 2 by 2 makeing 7/2 into 14/4 add the two together 13/4+14/4= 27/4 then simplify down to 6 3/4
They cycled in total 6 3/4 miles.
What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.
Given that;
Padma cycles 3 1/4 miles.
And, Josh cycles 7/2 miles.
Now,
Since, Padma cycles 3 1/4 miles. Josh cycles 7/2 miles.
Hence, The total cycled by both = 3 1/4 + 7/2
= 13/4 + 7/2
= 13/4 + 14/4
= (13 + 14) / 4
= 27/4
= 6 3/4 miles
Thus, They cycled in total 6 3/4 miles.

work out the percentage change when a price of £70 is decreased to £49
Answer:
30% decrease in price
Step-by-step explanation:
Since 70-49=21, we know that the price decreased by 30 pounds. The formula to find a percentage decrease is that you should then divide the original number(70) by 21(that equals 0.3!) 0.3 as a percentage would then be 30%, so the answer is there is a 30% decrease in price.
State the number of possible real zeros and turning points of f(x) = x7 – 6x6 + 8x5. Then determine all of the real zeros by factoring.
=
Answer:
steps below
Step-by-step explanation:
f(x) = x⁷ – 6x⁶ + 8x⁵
f'(x) = 7x⁶ - 36x⁵ + 40x⁴
= x⁴ (7x² - 36x + 40) ... (1)
Critical point (x,y): x = 0 , x = (36 ± √(-36)²-4*7*40) / (2*7) = (18±2√11) / 7
x = 0 or x = 3.5 or x = 1.6
plug into (1): y = 0 , y = -394.3 , y = 10.1
extreme : maximum (1.6 , 10.1) minimum (3.5 , -394.3) ... turning points
x⁷ – 6x⁶ + 8x⁵ = x⁵ (x² - 6x + 8) = x⁵ (x-2) (x-4) =0
real zeros: x = 0, x=2, x=4
Ben is a waiter at a restaurant. on Saturday, Ben got up at 6:30am, started work at X.am and finished work at X.pm. how long in hours did Ben work that Saturday
Answer:
12 hours
Step-by-step explanation:
X = 6:30
From 6:30 am to 6:30 pm = 12 hr
The number of hours that Ben worked at the restaurant can be calculated by the expression, Xpm - Xam.
The number of hours that Ben worked can be represented as:
= Time he finished working - Time he started working
= X pm - X am
If for instance, he started work at 7 am and finished at 12 pm, he would have worked:
= 12 - 7
= 5 hours
The expression that shows the length of time he worked can therefore be concluded to Xpm - Xam.
