Harold can buy 2 pounds of bananas for $7. Write an equation to represent the cost, c , for b bananas.
The equation representing the situation is c = 3.5b
What is an equation?An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Harold can buy 2 pounds of bananas for $7.
Since, he can buy 2 pounds in $7 so, 1 pound in = 7/2 = $3.5
So, when he will buy b pounds of bananas he will spend = $3.5b
So, if c is the total cost for b pounds of bananas, then the equation representing the total cost for b pounds of bananas will be,
c = 3.5b
Hence, c = 3.5b is the equation that represent the cost, c, for b bananas.

Answer:
a) y = -7/640x^2 +7/4x
b) y = -7/640(x -80)^2 +70
Step-by-step explanation:
a) Given the equation in standard form:
y = ax^2 +bx +c
we can use the points (0, 0), (80, 70), and (160, 0) to find the values of a, b, c.
a·0 +b·0 +c = 0
a·80^2 +b·80 +c = 70
a·160^2 +b·160 +c = 0
The first equation tells us that c=0, so we can write a reduced matrix for the last two equations. The augmented matrix is ...
[tex]\left[\begin{array}{cc|c}6400&80&70\\25600&160&0\end{array}\right][/tex]
A matrix solver finds the solution to be ...
a = -0.0109375 = 7/640, b = 1.75 = 7/4
The standard-form equation for Money's path is ...
y = -7/640x^2 +7/4x
__
b) Factoring out -7/64, we have ...
y = -7/640(x^2 -160x)
adding and subtracting the square of the x-coefficient, we have ...
y = -7/640(x^2 -160x +6400) +70
y = -7/640(x -80)^2 +70
the sum of 2 numbers is 49. Twice the smaller number is 97 less than 3 times the larger number. What are the numbers?
Answer:
let the larger and smaller number be x and y respectively
first condition
x + y = 49
second condition
3x = 2y+97
3x-2y =97
Multiplying first condition by two and adding both equations
2x + 2y = 98
3x -2y = 97
5x = 195
x = 195/5 = 39
putting the value of x in
x + y = 49
y = 49 -39 = 10

The Star television costs $750 more than the Jupiter television. The two models cost $2,600 all together. Sandra writes an equation to find the cost of the two models. If c represents the cost of the Jupiter television, which of the following would be true when verifying the solution of the equation? Check all that apply. Sandra substitutes c = 925 into the equation c + (c + 750) = 2,600. Sandra substitutes c = 925 into the equation c + (c minus 750) = 2,600. Sandra finds a true statement after substituting 925 into the equation. Sandra finds a false statement after substituting 925 into the equation. When Sandra evaluates the equation with c = 925, she subtracts 750 from 925. Then, she adds that sum to 925. She finds that the value is not equal to 2,600. When Sandra evaluates the equation with c = 925, she adds 925 to 750. Then, she adds that sum to 925. She finds that the value is 2,600.
Answer:
A. Sandra substitutes c = 925 into the equation c + (c + 750) = 2,600.
C. Sandra finds a true statement after substituting 925 into the equation.
F. When Sandra evaluates the equation with c = 925, she adds 925 to 750. Then, she adds that sum to 925. She finds that the value is 2,600.

how do u add really big fractions
Answer:
It depends on your situation
Step-by-step explanation:
If you have a mixed fraction, for example: 5 23/3000 + 101 777/3000 you would have to make them irrational numbers and add them. Like so: 3000x5 = 15000. 15000+23 = 15023. 15023/3000. Same process but this time you get 303777/3000. You then add the numerators (top numbers) and you'll get the sum over 3000.
For regular fractions you simply add the numerators. If your denominators are not the same, you need to find a common term that both can fit into. If the denominators are not the same, no matter the size of the fraction, you cannot add it.

Step-by-step explanation:
Time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.
Given,
Time Temperature (°F)
5:53 a.m. 60.1
6:53 a.m. 60.1
8:53 a.m. 66.9
11:53 a.m 75.2
3:53 p.m. 78.1
From 5:53 a.m. to 6:53 a.m. the temperature is constant. So average rate of change per hour is 0.
From 6:53 a.m to 8:53 a.m. the temperature is increasing from 60.1 to 66.9 or 6.8 in 2 hours . So average rate of change per hour is [tex]\frac{6.8}{2} =3.4[/tex].
From 8:53 a.m. to 11:53 a.m the temperature is again increasing from 66.9 to 75.2 or 8.3 in 3 hours. So average rate of change per hour is [tex]\frac{8.3}{3} =2.76[/tex].
From 11:53 a.m to 3:53 p.m. the temperature is again increasing from 75.2 to 78.1 or 2.9 in 4 hours. So average rate of change per hour is [tex]\frac{2.9}{4}=0.725[/tex].
Now clearly from the above points time interval 6:53 a.m to 8:53 a.m, the average rate of change per hour the greatest.

A bouncing ball reaches a height of 27 feet at its first peak 18 feet at its second peak and 12 feet at its third peak Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak
Answer: 8
Step-by-step explanation:
A Geometric sequence can be used:
To Model this sequence you need to use this formula
A (subscript n) = Ar(n-1)
a = value of the first term
n = the # of the term you want to find (For example, if you want to find the term number 3, it is 12)
r = the common ratio, this is obtained by dividing the second term in the sequence by the first.
So the value of r is = 2/3 because 27 times 2/3 = 18 which is the second term
n = 4 since you want to find the 4th term in the sequence
Plug it in and results are
4th term = 27(2/3)^(4-1) = 8
Sample Response:
There is a common ratio of 2/3 between the height of the ball at each bounce. So, the bounce heights form a geometric sequence: 27, 18, 12. Two-thirds of 12 is 8, so on the fourth bounce, the ball will reach a height of 8 feet.
the double of a number divided by 3 is less than 8
Answer:

Because of road construction in one city, commuters were advised to plan that their Monday morning commute would take 150% of their usual commuting time. Explain what this means.
Answer:
Kindly check explanation
Step-by-step explanation:
Let :
Original commute time = x
Commute time due to road construction = 150% of original commute time
Hence, commute time due to road construction :
(150 / 100) * x
0.15x
Hence, the implication of the road construction in progress means that it will now take additional half of the usual time it takes them on a Monday morning.
For instance, an individual whose usu commute time is 10 minutes in the morning will now take :
1.5x = 1.5(10) = 15 minutes commute time on a Monday morning.

1. One factor is a two digit number between 1 and 10 2. One factor is a two digit number between 1 and 10 ( different from the first) 3. The product is greater than 8. But less than 10
Answer: 3.5 * 2.5 = 8.75
Step-by-step explanation:
The factors are to be less than 10 but are should be two digit numbers. The only way this is possible would be if they had decimals.
Which two numbers below 10 can give a product less than 10 but more than 8?
3 and 3 would give 9 which is the closest to our constraints.
Both numbers cannot be similar however and have to have a decimal but the factors should be around 3 but not up to 4 as this would pass the 10.
3.5 * 2.5 = 8.75 would work.

Veronica is shopping for school clothes. She wants to buy pants and shirts. The cost of her clothes can be found using the expressions 30x+ 25y where x is the number of pants and y is the number of shirts. She will also pay 8 tax. If Veronica buys eight shirts and two pairs of pants use the expression from question 4 to determine the total cost of the bill including 8% tax
Answer:
$280.80
Step-by-step explanation:
Given:
C = 30x+ 25y
Where,
C = total cost
x = number of pants
y = number of shirts.
If Veronica buys eight shirts and two pairs of pants
C = 30x + 25y
= 30(2) + 25(8)
= 60 + 200
= 260
C = $260
Sales tax rate = 8%
Amount of sales tax = 8% of $260
= 8/100 × 260
= 0.08 × 260
= $20.80
Total cost of the bill including 8% tax = $260 + $20.80
= $280.80
