Answer:
Total number of dimes collected = 50
Step-by-step explanation:
Let the number of dimes collected = d
And the number of nickels collected = n
On day collection in nickels and dimes = $6.55
Since, 1 nickel = $0.05
Therefore, 'n' nickels = 0.05n
And 1 dimes = $0.10
Value of 'd' dimes = $0.10d
Total value of 'n' nickels and 'd' dimes = $(0.05n + 0.10d)
So the equation for the total value will be,
0.05n + 0.10d = 6.55
5n + 10d = 655 --------(1)
Number of nickels was 6 more than half the number of dimes.
n = [tex]\frac{d}{2}[/tex] + 6 ------(2)
By substituting the value 'n' from equation (2) to equation (1)
5([tex]\frac{d}{2}[/tex] + 6) + 10d = 655
[tex]\frac{5d}{2}[/tex] + 30 + 10d = 655
[tex]\frac{25d}{2}[/tex] = 655 - 30
25d = 625 × 2
d = [tex]\frac{1250}{25}[/tex]
d = 50
Therefore, total number of dimes collected = 50

24=6c
SHOW WORK
Answer:
c = 4
Step-by-step explanation:
6c = 24
(divide 6 by each number to get eh variable by itself)
6c = 24
/6 /6
c = 4
To check work:
insert 4 for c into equation
6(4) = 24
24 = 24
One hundred deer were released into a wildlife preserve. The population of deer over a certain number of years is shown.
What degree polynomial could be used to model these data?
Answer:
Quartic
Step-by-step explanation:
The missing dataset showing the population of deer is shown below:
[tex]\text{Time (years) \ \ \ \ 0 \ \ \ \ 0.5 \ \ \ \ 1 \ \ \ \ 1.5 \ \ \ \ 2 \ \ \ \ 2.5 \ \ \ \ 3 \ \ \ \ 3.5 \ \ \ \ 4}[/tex]
[tex]\text{Population \ \ \ 100 \ \ \ 111 \ \ \ 144 \ \ \ 193 \ \ \ 252 \ \ \ 309\ \ \ 352\ \ \ 363 \ \ \ 324}[/tex]
The degree of polynomial best suitable to model the above dataset is Quartic
[tex]\text{Quartic is an algebraic equation or function of the fourth degree }[/tex]
The polynomial model of the above data is:
P(x) = -2x⁴ + 46x² + 100
Answer:
Quartic
Step-by-step explanation:

Answer:
[tex] - \frac{1}{2} ( \frac{4}{5} - 8y) \\ = - \frac{4}{10} + \frac{8y}{2} \\ = - \frac{2}{5} + 4y \\ = \frac{ - 2 + 5 \times 4y}{5} = \frac{ - 2 + 20y}{5} \\ - 2 + 20y = 0 \\ 20y = 2 \\ y = \frac{1}{10} [/tex]

Quien me puede ayudar es U R G E N T E The GCF of 54, 76 and 114 is: 2 6 4 9 1 The GCF of 35, 50 and 120 is: 2 4 5 25 2 Find the GCF of 12, 16 and 20 1 If the GCF of 56 and 120 is c, find the result of 24\div c24÷c
Responder:
a) 2
b) 5
c) 4
d) 3
Explicación paso a paso:
Debemos encontrar el MCD de los siguientes números
a) 54, 76, 114
encontrar los factores primos de cada
54 = 2 * 3 * 3 * 3
76 = 2 * 2 * 19
114 = 2 * 2 * 2 * 2 * 3 * 3
De los factores anteriores, podemos ver que solo 2 es común a todos los factores, por lo tanto, el MCD de 54, 76 y 114 es 2
b) Para 35, 50 y 120
35 = 5 * 7
50 = 2 * 5 * 5
120 = 2 * 2 * 2 * 3 * 5
De los factores anteriores, podemos ver que solo 5 es común a todos los factores, por lo tanto, el MCD de 35, 50 y 120 es 5
c) Para 12, 16 y 20
12 = 2 * 2 * 3
16 = 2 * 2 * 2 * 2
20 = 2 * 2 * 5
De los factores anteriores, (2 * 2) es común a todos ellos, por lo tanto, el MCD de 12, 16 y 20 es 4
d) Para 56 y 120
56 = 2 * 2 * 2 * 7 = 8 * 7
120 = 2 * 2 * 2 * 3 * 5 = 8 * 3 * 5
De los factores anteriores, podemos ver que solo 8 es común a todos los factores, por lo tanto, el MCD de 56 y 120 es 8.
Por tanto, c = 8
Necesario
24 / c
= 24/8
= 3
Por tanto, el resultado de 24 / c es 3

An angle measures 150°. What is the measure of its supplement?
Answer:
The supplement is = 180-150 i.e30
Step-by-step explanation:
Let the another Angle be x then
x + 150° = 180° {being supplementary angles }
x = 180° - 150°
x = 30°

Solve for r.
–6(r − 98) = 78
Answer:
r = 85
Step-by-step explanation:
→ -6 ( r - 98 ) = 78→ r - 98 = -13→ r = -13 + 98→ r = 85conclusion:
so the value of r is 85
Step-by-step explanation:
First, divide both sides of the equation by -6.
-6(r-98)÷6=78÷6
This gives us r-98=-13
Then, add 98 to both sides.
r-98+98=-13+98
The answer is r=85
7. 8x - 4= 4(2x + 1) have how many solutions
Answer:
0
Step-by-step explanation:
Let's solve for x
8x-4=4(2x+1)
8x-4=8x+4
0= 8
This obviously isn't true and therefore there are 0 solution
Answer:
No solution as both side not equal.
solve the equation -30p-2=58 for p.
Answer:
p=-2
Step-by-step explanation:
1.Combine like terms on both sides.
2.Subtract 6 y 6y 6y on both sides to keep the variable y to the left side only.
3.Add 11 to both sides of the equation.
4.Finally, divide both sides by −10 to get the solution.

Mark took his family to the movies and spent a total of 78$ on tickets he also bought a soda for each family member each sodas cost 4.25 if mark spent a total of 102,50 on sodas and tickets. How much sodas did he buy
Answer: He bought about 6 sodas.
Step-by-step explanation:
Given: Tota cost of tickets = $ 78
Cost of each soda = $4.25
Total cost of sodas and tickets = 102.50
Let x = Number of sodas purchased
Then
[tex]78+4.25x=102.50\\\\\Rightarrow\ 4.25x=102.50-78\\\\\Rightarrow\ 4.25x=24.5\\\\\Rightarrow\ x= \dfrac{24.5}{4.25}\\\\\Rightarrow\ x\approx6[/tex]
Hence, he bought about 6 sodas.

There are 8 students on the school chess team. They need to raise at least $760 for a field trip. Their advisor says they still need to raise 85% of the funds, and she wants each of them to raise an equal share of the money still needed. Diego wrote and solved the inequality 8m + 0.85(760) ≥ 760 to find the least amount of money, m, each student on the chess team needs to raise. He says the solution is m ≥ $14.25. Diego is incorrect. What should be the correct solution? *
