katie wants to buy a watermelon from the store if the watermelon costs $1.20 per kilogram and the watermelon weighs 6 kilograms how much money will katie spend on the watermelon?
Answer:
p=0.60w
Step-by-step explanation:
Let
p ----> the price of a watermelon in dollars
w ---> the weight of a watermelon in pounds
In this problem we have a proportional relationship
Remember that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or
In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin
In this problem
p=kw
The value of the constant of proportionality k is the same that the unit rate
Find out the unit rate
Divide the total cost by the total weight
k=4.38/7.3=0.60per lb
substitute in the equation
p=0.60w

Find the slope of the line passing through the points (-4, 2) and (3, 2)
Answer:
0
Step-by-step explanation:
The slope of a line is also known as the change in the line. it is often referred to as ([tex]\frac{rise}{run}[/tex]) and can be found using the formula, ([tex]\frac{y_2-y_1}{x_2-x_1}[/tex]). Substitute in the given points and solve for the slope,
[tex]\frac{(2)-(2)}{(3)-(-4)}[/tex]
Simplify,
[tex]\frac{0}{3+4}\\\\\frac{0}{7}[/tex]
The slope of the line is (0).

Josephine bought 8 gallons of milk.
How many liters does that equal?
Answer:
Either 30 or 32, depending on if your teacher wants you to use exact decimals, or rounded numbers
Step-by-step explanation:
Usually people round liters to equal 4 per gallon, which would give you 32.
However, a liter is technically 3.785 liters per gallon- and this exact number would give you 30 as an awnser.
I'd say 32 is the safer awnser, unless your teacher has given you the number 3.785 decimal amount to use instead.

Answer:
Step 3 contains error.
Step-by-step explanation:
The given equation is :
[tex]\dfrac{1}{4}(\dfrac{1}{3}k+9)=6[/tex]
Step 1.
Cross multiplying,
[tex](\dfrac{1}{3}k+9)=24[/tex]
Step 2.
Subtract 9 from both sides
[tex]\dfrac{1}{3}k+9-9=24-9\\\\\dfrac{1}{3}k=15[/tex]
Step 3.
Cross multiplying
[tex]k=15\times 3\\\\k=45[/tex]
So, there is an error in step 3. The correct answer should be 45.
What should we find in order to determine how many square feet of plywood are needed to make a rectangular prism
Answer:
surface area
Step-by-step explanation:
A rectangular prism is an optical element which is transparent with flat sides that can pass or reflect light. A rectangular prism is a cube where all its sides are the same.
In the context, in order to find the total square feet of plywood needed to make a prism we have to determine its surface area.
The total surface area of a rectangular prism can be found out by the formula :
A = 2 (hl + lw + wh)
where, h = height of the rectangular prism
l = length of the rectangular prism
w = width of the rectangular prism

C) 12.5
The length of BC = 12.5cm
Step-by-step explanation:
Step(i):-
Given that ΔABC
Given that AB = 15cm and ∠A = 40°
we will use trigonometric function
[tex]tan x = \frac{oppositeside}{adjacentside}[/tex]
[tex]tan 40^{0} = \frac{BC}{AB} = \frac{BC}{15}[/tex]
Step(ii):-
we know that tan40° = 0.83909
[tex]tan 40^{0} = \frac{BC}{15}[/tex]
BC = 15 × tan 40°
BC = 12.58649
BC = 12.5cm
Final answer:-
The length of BC = 12.5cm
Part A: To the nearest tenth of an inch, what was the circumference of the circular pie before the slice was
cut out?
Part B: To the nearest inch, what was the area of the circular pie before the slice was cut out?
Part C: To the nearest tenth of an inch, what is the area of the slice of pie that was cut out?
Part D: To the nearest inch, what is the length of the curst for the slice of pie that was cut out?
Next Question
Question 1 of 2
Answer:
Part A
The circumference of the circular pie before the slice was cut out is approximately 69.1 inches
Part B; The area of the circular pie before the slice was cut out is approximately 380 in.²
Part C
The area of the slice of pie that was cut out in approximately 40 in.²
Part D;
The length of the crust for the slice of pie is approximately 7 inches
Step-by-step explanation:
Part A
The shape of the pie = Circular shape
The radius of the pie, r = 11 inches
The circumference of a circle = 2·π·r
Therefore, we have;
The circumference of the circular pie before the slice was cut out, 'C', is given as follows;
Where;
r = 2 inches
C = 2 × π × 11 inches = 22·π inches ≈ 69.115 inches
The initial circumference of the circular, C ≈ 69.115 inches
To the nearest tenth of an inch, we have;
The initial circumference of the circular, C ≈ 69.1 inches
Part B; The area of a circle, A = π·r²
Therefore;
For the circular pie before the slice was cut out, A = π·(11 in.)² ≈ 380.133 in.²
To the nearest square inch, we have;
The area of the circular pie before the slice was cut out, A ≈ 380 in.²
Part C
The area of the slice of the pie that was cut out, A is given by the area of a sector of a circle as follows;
[tex]The \ area \ of \ a \ sector, A = \dfrac{\theta}{360 ^{\circ}} \times \pi \cdot r^2[/tex]
The angle of the sector formed by the slice of pie that was cut out, θ = 38°
Therefore, the area of the slice of pie that was cut out, 'A', to the nearest tenth of a square inch is given as follows;
A = 38/360 × π × (11 in.²) = 40 in.²
The area of the slice of pie that was cut out, A = 40 in.²
Part D;
The length of the crust of the slice of pie that was cut out is given by the arc length of the sector of the circular pie the slice of pie represent as follows;
[tex]Arc \ length = \dfrac{\theta}{360 ^{\circ}} \times 2\cdot \pi \cdot r[/tex]
Therefore for the slice of pie, to the nearest inch, we have;
[tex]Arc \ length = \dfrac{38 ^{\circ}}{360 ^{\circ}} \times 2\times \pi \times 11 \, in. \approx 7 \, in.[/tex]
The length of the crust for the slice of pie ≈ 7 in.
In circle G with m_FGH = 60 and FG = 19 units, find the length of arc FH.

Step-by-step explanation:
Jace recorded the grade-level and instrument of everyone in the middle school School of Rock below. Seventh Grade Students Eighth Grade Students Instrument # of Students Instrument # of Students 11 Guitar 13 14 Guitar Bass Drums Keyboard Bass Drums Keyboard 13 8 14 3 Based on these results, express the probability that a seventh grader chosen at random will play an instrument other than bass as a percent to the nearest whole number.
please answer , I have no idea how to do this
Using the table, it is found that there is a 77% probability that a seventh grader chosen at random will play an instrument other than bass.
-----------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.The table is given at the end of this question.From the table:
There are 12 + 10 + 9 + 12 = 43 7th grade students.Of those, 33 play an instrument other than the bass.Then:
[tex]p = \frac{33}{43} = 0.77[/tex]
0.77 = 77% probability that a seventh grader chosen at random will play an instrument other than bass.

Answer:
Step-by-step explanation:
y = 3x + 4
Plugin x = 3 in the equation,
y = 3*3 + 4
= 9 + 4
y = 13
Plugin x = 4 in equation,
y = 3*4 + 4
= 12 + 4
y = 16
Plugin x = 5 in the equation,
y = 3*5 + 4
= 15 + 4
y = 19
2) y =x - 7
Plugin x = 10 in the equation
y = 10 - 7
y = 3
Plugin x = 15 in the equation
y = 15 - 7
y = 8

What is the measure of the missing exterior angle, in degrees?
Answer:
exterior angle is equal to the sum of two interior opposite angle
?=53+53=106°
missing exterior angle =106°
The measure of the exterior angle is 106°.
What is an exterior angle?Exterior angles are angles that are parallel to the inner angles of a polygon but lie on the outside of it.
Given that, a triangle has two interior angles 53° and 53° and an exterior angle x,
Since, we know that, sum of opposite two interior angles of a triangle is equal to measure of exterior angle.
Therefore,
53° + 53° = x
x = 106°
Hence, the exterior angle is 106°
