If the computer costs $2150 and Melissa puts
$150 away each month, how long will it take her
to save enough money to buy the computer?
Answer:
14 months and 1/3 of a month
Step-by-step explanation:
We can find how many months it will take by dividing the cost by the amount she puts away each month:
2150/150 = 14.33
So, it will take her 14 and 1/3 of a month

Write a linear equation that represents the arithmetic sequence 10, 8, 6, 4, ...
A. an = 10 - 2(n-1)
B. an = 10 + 2(n + 1)
C. an = 2 + 10(n-1)
D. an = 10 + 2(n-1)
Answer:
A
Step-by-step explanation:
The n th term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 10 and d = 8 - 10 = - 2, thus
[tex]a_{n}[/tex] = 10 - 2(n - 1) → A
Answer:
A
Step-by-step explanation:

How long will it take an airplane to travel 1,250 km if it is traveling at 150 km/hr ?
Answer:
[tex]\boxed{Time = 8.33 hrs}[/tex]
Step-by-step explanation:
Given:
Distance = S = 1250 km
Speed = v = 150 km/hr
Required:
Time = t = ? hrs
Formula:
Speed = Distance / Time
Solution:
Rearranging the formula
=> Time = Distance / Speed
=> Time = 1250/150
=> Time = 8.33 hrs
Find the value of x in the triangle
shown below.
Answer:
x=62
Step-by-step explanation:
In an isosceles triangle opposite sides are equal and sum of the sides is 180 degree
So, if we name them 'angle a', 'angle b' and 'angle c'
angle a= 56
a+b+c= 180
using the isosceles triangle formula b=c,
56+b+c=180
name b,c as x
56+2x=180
2x= 180-56
2x= 124
x=62

The value of x in the triangle will be 62°
What is mean by Triangle?
A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
Two sides of triangle = 6
So, This is an isosceles triangle.
Third side of a triangle = 5.7
Now,
Since, The given triangle is an isosceles triangle.
So, It has measure of two angles = x°
And, The measure of third angle = 56°
Since, The sum of all angles of a triangle = 180°
Substitute all the value of angles, we get;
x° + x° + 56° = 180°
Solve for x as;
2x + 56 = 180
Subtract 56 both side,
2x + 56 - 56 = 180 - 56
2x = 124
Divide by 2, we get;
x = 62°
Thus, The value of x in the triangle will be 62°

A particular beach is eroding at a rate of 4 centimeters per year. A realtor converts this rate to millimeters per day. Which expression, when evaluated, results in the correct units and numerical value? Which expression converts 100 inches per minute to feet per minute? Katrina drinks 0.5 gallons of water per day. Which expression shows how to find the number of cups of water she drinks in a week? There are 16 cups in a gallon.
Answer:
0.109589 millimeters per day.
Step-by-step explanation:
10 mm = 1 cm
4 cm = 4 × 10
= 40 mm
365 days = 1 year
rate to millimeters per day = 40 mm in 365 days
= 40/365 mm/day
= 8/73 mm/day
or = 0.109589 mm/day.
Rate to millimeters per day = 0.109589 millimeters per day.
Step-by-step explanation:
the first question is the first answer 4cm/1 years x 10mm/1cm x 1 year/ 365 days
the second question is the third answer 100 inches/1 minute x 1 foot/ 12 inches
Find the area of the composite shape...
Answer:
166cm^2
Step-by-step explanation:
To calculate the area of the composite shape, find the area of rectangle and subtract the area of the triangle from it:
Area of rectangle = 16 x 11 = 176cm^2
Area of triangle = 1/2 x 4 x 5 = 10cm^2.
Since the shape is a rectangle, which the supposed shape of a triangle removed, subtract the area of triangle from that of rectangle:
176-10 = 166cm^2

Answer: Y = 2 ; 3 ; 4
Step-by-step explanation:
Given the rule : y=1/4x + 1
X = 4, 8, 12
When x = 4
y = 1/4(4) + 1
y = 1 + 1
y = 2
When x = 8
y = 1/4(8) + 1
y = 8/4 + 1
y = 2 + 1
y = 3
When x = 12
y = 1/4(12) + 1
y = 12/4 + 1
y = 3 + 1
y = 4

A large solar panel can generate power at a maximum rate of 400400400 kilowatts per day. It generates power at a constant rate when the sky is cloudy, and it generates power at a constant rate when the sky is clear. Let CCC represent the number of hours when the sky is cloudy and LLL represent the number of hours when the sky is clear during which the solar panel can generate power without exceeding its capacity. 5C+32L \leq 4005C+32L≤4005, C, plus, 32, L, is less than or equal to, 400 According to the inequality, at what rate does the solar panel generate power when the sky is cloudy, and at what rate does it generate power when the sky is clear?
Answer:
Rate of power generation when the sky is cloudy= 5 watts per hour.
Rate of power generation when the sky is clear = 32 watts per hour.
Step-by-step explanation:
A large solar panel can generate power at a maximum rate of 400 kilowatts per day.
Let the number of hours when the sky is cloudy =C
Let the number of hours when the sky is clear = L
Given the inequality:

Meline has 4 different coloured crayons and 2 different boxes. How many different ways can Meline put all 4 different crayons into 2 boxes so that each box has at least 1 crayon?
Answer:
3 different waysStep-by-step explanation:
If Melinda has 4 different crayon and 2 different boxes and she is to put all 4 crayons into the two boxes so that each box has at least 1 crayon, this can be achieved as follows. Note that at least one crayon must be in each box, this means no box must be left empty. Each box can take any number of crayon from 1 and above.
First box Second box
1 crayon 3 crayons (first way)
2 crayons 2 crayons (2nd way)
3 crayons 1 crayon (3rd way)
This means that crayons can be divided into each box in 3 different ways provided that each box has at least 1 crayon.

Answer:
[tex]A2+By=C[/tex]
Step-by-step explanation:
Well standard form is [tex]Ax+By=C[/tex].
And we have x = 2 meaning that x is 2 so the standard is [tex]A2+By=C[/tex].
So basically if we know that x is 2 and x is in the standard for equation we can just plug it in.
So [tex]Ax+By=C[/tex]
x -> 2
So answer is [tex]A2+By=C[/tex]
2A+By=C is the standard form of X=2
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The standard form of a linear equation is Ax+By=C.
A times of x plus B times of y equal to C
A, B, and C are constants,
x and y are variables.
Standard form lets us quickly find the x- and y- intercepts.
By given x value is 2.
Now plug in the value of x in standard form of equation.
2 times of A plus B times of y equal to C
2A+By=C
Hence 2A+By=C is the standard form of X=2

The second angle of a triangle is double the first angle. The third angle is 40 less than the first angle. Find the three angles.
Answer:
Angle 1: 55
Angle 2: 110
Angle 3: 15
Step-by-step explanation:
Angle 1: x
Angle 2: 2x
Angle 3: x-40
The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).
y is inversely proportional to x . When y = 25 , x = 4 Work out y when x = 20
Answer: 125
Step-by-step explanation:
4/25 = 20/Y
Cross multiply to get the equation
4Y = 500
Divide both sides by 4
Y=125
y=5 when x=20.
Given that, y is inversely proportional to x. When y = 25 , x = 4.
We need to find the y value when x=20.
What is inversely proportional?Inversely proportional variables or quantities are those in which if one variable increases the other will decrease, and if one variable decreases the other increases.
Now, y∝1/x
⇒y=k/x
⇒25=k/4
⇒k=100
Thus, the y value when x=20.
y=100/20=5
Therefore, y=5 when x=20.
