A group of 4444 friends is playing cards. The deck has 70707070 cards. To start the game, the dealer makes a pile of 15151515 cards in the center. Then she deals the remaining cards one at a time to each player until all the cards are gone.
What is the greatest number of cards any player will have after all the cards are dealt?
cards
Answers
Answer:
12502 cards
Step-by-step explanation:
Given:
» total of 70707070 cards of the deck
» 15151515 cards were taken and put in a pile
Solve:
1. So, you can subtract 15151515 from 70707070 to find how many cards are left:
70707070 - 15151515 = 55555555
2. Now, there are 55555555 cards remaining in the deck since 15151515 cards were taken to put in a pile. Since the dealer deals the remaining cards to 4444 people, you can just do 55555555 divided by 4444 to find how many cards each person gets:
55555555 ÷ 4444 = 12501.25
3. 12501.25 is the exact number of cards each person gets, but you can’t have a fraction/part of a card. You have to find a specific remaining number:
0.25 is the same as \(\frac{1}{4}\), and so convert \(\frac{1}{4}\) into a fraction with a denominator of 4444, but is still equivalent to \(\frac{1}{4}\): You’ll get \(\frac{1111}{4444}\), which is correct because it’s still equivalent to \(\frac{1}{4}\)
4. So, the remaining 55555555 cards divided by 4444 people is 12501 cards and a remainder of 1111 cards. The 1111 cards can be distributed upon the players, but not everyone can get it. Since 12501 were to given to the players and after the remaining 1111 were also distributed, this means that some will have 12501 cards and others will have 12502 cards.
Answer: So, the greatest number of cards any player will have after all the cards are dealt is 12502 cards.

39x-9x=-45+15

x=-1
Answer:
\( \sf \: x = - 1\)
Step-by-step explanation:
Given equation,
→ 4x + 5(7x - 3) = 9(x - 5)
Now the value of x will be,
→ 4x + 5(7x - 3) = 9(x - 5)
→ 4x + 35x - 15 = 9x - 45
→ 39x - 15 = 9x - 45
→ 39x - 9x = -45 + 15
→ 30x = -30
→ x = -30 ÷ 30
→ [ x = -1 ]
Hence, the value of x is -1.

The scale is done in a base of 10 and the grams are in its center with value 1.
To convert from smaller units to grater units you have to divide the given measurement by 10
And to convert from greater units to smaller units you have to multiply by 10.
For example if you have 1mg and want to convert it to grams you have to divide the value 3 times by 10, i.e. divide the value by 1000
\(\frac{1mg}{1000}=0.001g\)If you want to convert 1 Kg into 1 decagram, multiply the value two times by 10, i.e. multiply it by 100

1. Isosceles Triangle The two equal sides of an isosceles triangle are each 42
centimeters. If the base measures 30 centimeters, find the height and the
measure of the two equal angles. Round your answer to the nearest tenth.
Answers
Answer:
1. H = 29 cm
2. θ = 44°
Step-by-step explanation:
1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:
\( L^{2} = H^{2} + B^{2} \)
Where:
L: is the sides of the isosceles triangle = 42 cm
B: is the base = 30 cm
H: is the height =?
Then, the height is:
\( H = \sqrt{L^{2} - B^{2}} = \sqrt{(42 cm)^{2} - (30 cm)^{2}} = 29.4 cm = 29 cm \)
2. The two equal angles (θ) can be found using the following trigonometric identity:
\( cos(\theta) = \frac{B}{L} \)
\( \theta = cos^{-1}(\frac{30 cm}{42 cm}) = 44.4^{\circ} = 44^{\circ} \)
Hence, the two equal angles are 44°.

a data collected by a final year statistics students shows that , of the 120 cars which took the road worthiness test at DVLA office in kumasi in june 2023, only 60% passed .Among those who failed due to faults in brakes, light and steering occured as follows : brake only 14, brakes and steering 7, brake and light 10, steering and light only 3, brakes , steering and light 4. Both the number of cars that failed due to fault in steering only is the same as those that failed due to faults in light only. i. how many cars had faulty light ii. find the number of cars which had only one fault iii. find the number of cars which had at least two fault iv. find the number of cars which had fault in brake or light but not steering
Answers
i. 13 cars had faulty light. ii. 13 cars had only one fault. iii. 27 + x cars had at least two faults.
What is percentage?
Percentage is a way of expressing a number or proportion as a fraction of 100. It is represented by the symbol "%".
i. To find the number of cars that had faulty light, we first need to find the total number of cars that failed the test. This can be calculated as:
Number of cars that failed = Total number of cars tested × (1 - Percentage passed)
Number of cars that failed = 120 × (1 - 0.60)
Number of cars that failed = 48
Now, we can use the information provided in the question to find the number of cars that had faulty light. According to the question, 10 cars failed due to brake and light faults, 3 cars failed due to steering and light faults, and the number of cars that failed due to light faults only is the same as the number of cars that failed due to steering faults only. Therefore, we can set up the following equation:
10 + 3 + x = number of cars that failed due to light faults
where x is the number of cars that failed due to steering faults only.
Since the number of cars that failed due to light faults only is equal to the number of cars that failed due to steering faults only, we can solve for x as follows:
10 + 3 + x = x
13 = x
Therefore, 13 cars had faulty light.
ii. To find the number of cars which had only one fault, we need to add up the number of cars that failed due to each individual fault (i.e. brake, steering, and light) and subtract the number of cars that failed due to multiple faults (i.e. brake and steering, brake and light, steering and light, and brake, steering, and light). This can be calculated as follows:
Number of cars with only one fault = (Number of cars that failed due to brake only) + (Number of cars that failed due to steering only) + (Number of cars that failed due to light only) - (Number of cars that failed due to multiple faults)
Number of cars with only one fault = 14 + 13 + x - (7 + 10 + 3 + 4)
Number of cars with only one fault = 13
Therefore, 13 cars had only one fault.
iii. To find the number of cars which had at least two faults, we can use the same equation as in part ii, but we don't subtract the number of cars that failed due to multiple faults. This can be calculated as follows:
Number of cars with at least two faults = (Number of cars that failed due to brake only) + (Number of cars that failed due to steering only) + (Number of cars that failed due to light only)
Number of cars with at least two faults = 14 + 13 + x
Number of cars with at least two faults = 27 + x
Therefore, 27 + x cars had at least two faults.

use differentials to approximate the value of sqrt(99.4). what is the percent error oin this calculation
Answers
The percentage error by calculating by differentials to approximate value of sqrt(99.4) = 0.00045 percentage.
For percentage error Here first we have to find the value of sqrt(99.4) by normal calculation and second we will calculate it by differential method then we will find the percentage error .
To approximate sqrt(99.4) we will use formula for linear approximation as given below
f(x) = f(c) + f′(c)(x−c)
and we are dealing with square root so we have to find the f(x) ad here
f(x) = √x
and we will calculate f'(x) and here it is
f'(x) = 1/(2√x)
Here, x=99.4 and we choose c =100 because that’s the closest perfect square number to 99.4. so
f(c) = f(100) = √100 = 10
f'(c) = f'(100) =1/(2√100) = 1/20
f(x) =f(c) + f′(c)(x−c)
f(x) = f(99.4)=f(100)+f'(100)(99.4-100)
=10+1/20*(-0.6)
=9.97
Here we find the value by differential = 9.97
and by simple calculation the value is = 9.96995486
ans percentage error = (real value - differential value)/100
= (9.96995486-9.97)/100 = 0.00045 percentage
