alina bought an ice cream cone for $3. her 4 ounce scope of ice cream is melting at rate of 0.5
Answer:
y=4-0.5x
Step-by-step explanation:
Step one:
given data
Alina bought an ice cream cone for $3
the weight of the ice cream is 4 ounce
the rate of melting is 0.5 ounce per minute
let the number of minutes taken for the ice cream to melt be x
and the weight after x minutes be y
Step two:
Hence the expression for the situation after x minutes is
y=4-0.5x
Which of the following do you use to tell whether a relationship is
proportional or not?
Answer:
The correct option to tell whether a relationship is proportional or not is;
[tex]\dfrac{y}{x}[/tex]
Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;
[tex]\dfrac{y}{x} = k = Contant[/tex]
Therefore we can use [tex]\dfrac{y}{x}[/tex] to tell whether a relationship is proportional or not proportional.
Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?
Answer:
Daniel is 8 years old now.
Step-by-step explanation:
From the word problem we can make the following two equations:
Let "K" be Kevin's age now and let "D" be Daniel's age now, then...
K = 3D
K - 4 = 5(D - 4)
Now we substate the value of K, and get...
K - 4 = 5(D - 4)
3D - 4 = 5(D - 4)
3D - 4 = 5D - 20
3D - 5D = - 20 + 4
- 2D = - 16
D = 8
Therefore Daniel is 8 years old now.

20% of $30 = $24
30% of $24 = 16.8
40% of $35 = $21
Explanation:
0.2 x 30 = 6
30 - 6 = 24
0.3 x 24 = 7.2
24 - 7.2 = 16.8
0.4 x 35 = 14
35 - 14 = 21

A home was purchased in 1985 for $125,000. If the value of the home increased 2.5% each year, what would be the value of the house by 2025? Round to the nearest whole number.
Answer: $335,633
Step-by-step explanation:
First find the number of years difference:
= 2025 - 1985
= 40 years
Use the compound interest formula to find the answer:
= Value * ( 1 + rate) ^ no. of years
= 125,000 * ( 1 + 2.5%)⁴⁰
= $335,633

Factor the expression using the GCF. 58+28=
Answer:
2(29+14)
Step-by-step explanation:
Given function:
To find the GCF of 58+28..Find the GCF of 58+28:
[tex]58=29[/tex]·[tex]2[/tex] [tex]28=14[/tex]·[tex]2[/tex]Rewrite:
[tex]2(29+14)[/tex]Therefore, using GCF, the new expression would be 2(29+14)..
The expression 58 + 28 can be factorized as 2 (29 + 14).
What is GCF?GCF which is the abbreviated form for Greatest Common Factor of two numbers, as the name implies, is the greatest common factor of both the numbers.
GCF of two numbers can be found using prime factorization.
Given the expression 58 + 28.
To find the GCF of two numbers, list the prime factors of these two numbers.
58 = 2 × 29
28 = 2 × 14 = 2 × 2 × 7
The only common factor is 2.
So the greatest common factor is 2.
58 + 28 = (2 × 29) + (2 × 14)
Taking the common factor of 2 outside the brackets,
58 + 28 = 2 (29 + 14)
Hence the expression 58 + 28 can be factorized as 2 (29 + 14) using the greatest common factor.

Solve liner equation for they variable
3x-5(x+6)=-2x-2(5+10)
Answer:
all numbers
Step-by-step explanation:
3x - 5(x + 6) = -2x -2(5 + 10)
Distribute on both sides.
3x - 5x - 30 = -2x - 10 - 20
Add 2x to both sides.
-2x - 30 = -2x - 30
-30 = -30
Since we get a true statement after only doing legal steps to solve the equation, the equation has an infinite number of solutions.

Work out the area of this circle. Take pi to be 3.142 and give your answer to 1 decimal place
Step-by-step explanation:
I think you have forgotten to attach the question.
Anyways....
In order to find the area of a circle use the formula:
π[tex]r^{2}[/tex] Where r is the radius
For example the radius is 3cm. The area of the circle will be:
π × [tex]3^{2}[/tex]
Since you have taken pi as 3.142...
3.142 × [tex]3^{2}[/tex]
3.142 × 9
= 28.278
In order to find the answer to 1 decimal place, check the number next to the number right after the decimal. Is it a number greater than or equal to 5? then add +1 to the number.

A trebuchet launches a pumpkin on a parabolic arc from a height of 47 ft at a velocity of 40 ft/s which gives the
following function equation h(t)= -16t^2 + 40t + 47. State the vocabulary term that is being described by the
following questions. Do not solve for any of the key features. questions a b c and d
a. When will the pumpkin reach the ground?
The pumpkin will reach the ground at
b. What is the maximum height the pumpkin reaches?
C. When does the pumpkin reach its maximum height?
d. What is the starting height of the pumpkin?
Answer:
a) 3.37 seconds
b) 75.85 feet
c) 1.25 seconds
d) 47 feet
Step-by-step explanation:
a) I could use kinematic equations here, but I'll use the one provided. Height as a function of time equals 0 when the pumpkin reaches the ground, so 0=(-16t^2)+40t+47 is your equation here. Solve for t. t=3.37
b) If you have a graphing calculator, just use maximum feature. If not, use the formula x=-b/2a. x=-40/-32, x=1.25.
Now, plug 1.25 in as t, and you'll get y=75.85ft
c) alreaady found in previous part
d) this is the constant in the formula, or the y-intercept, which is 47 (because there's no variable attached).

A piece of wire is 240 cm long.
Peter cuts two 45 cm lengths off the wire.
He then cuts the rest of the wire into as many 40 cm lengths as possible.
Work out how many 40 cm lengths of wire Peter cuts.
Answer:
so 240-90cm he cut off=195cm. Then 45x2=80cm so 195-90cm=105cm.
Therefore, 105 divided by 40=2.625 so he cut off 6 pieces of 40cm lengths overall
