Six cell phones weigh 46.2 ounces. Fourteen cell phones weigh 107.8 ounces. This relationship is an example of a proportional relationship. What is the constant of proportionality
Answer:
The constant is 7.7 . This is because the quantities are directly proportional so constant of proportionality is a/b or 46.2/6
A 25 ft ladder leans against a building. The ladder’s base is 13.5 feet from the building. Find the angle of elevation, which the ladder makes with the ground.
Answer:
57.3°
Step-by-step explanation:
A 25 feet ladder leans against a building.
The ladder's base is 13.5 feet from the building.
The ladder, the wall of the building and the ground form a right-angled triangle of:
Hypotenuse = 25 feet
Base = 13.5 feet
We are to find the angle of elevation which the ladder makes with the ground (or rather the angle created by hypotenuse and base)
Let's say the angle = X°
According to a trigonometric equation;
cos X° = adjacent side ÷ hypotenuse = [tex]\frac{13.5}{25}[/tex] = 0.54
[tex]cos ^{-1} X[/tex] = 57.5=3° (Answer rounded up to nearest one decimal place).
∴ The angle of elevation = 57.3°

ashley is baking a cake shaped as a right triangle. Two of the angles are measurement of 5x and 10x. What is the value of x?
Answer:
A. 6
Step-by-step explanation:
Since, cake is of right triangled shape, so measure of its one angle would be 90° and the sum of the measures of the remaining two angles will also be equal 90°.
Therefore,
5x +10x = 90
15x = 90
x = 90/15
x = 6
The cylindrical part of a architectural column has a height of 325 cm and a diameter of 30 cm. Find the volume of the cylindrical part of the column. Use 3.14 for π and round your answer to the nearest cubic centimeter if needed.
Answer:
[tex]V=229612.5\ cm^3[/tex]
Step-by-step explanation:
Given that,
The height of a cylinder, h = 325 cm
Diameter, d = 30 cm
Radius, r = 15 cm
We need to find the volume of the cylinder. The formula for the volume of a cylinder is given by :
[tex]V=\pi r^2h[/tex]
Putting all the values,
[tex]V=3.14\times (15)^2\times 325\\\\V=229612.5\ cm^3[/tex]
So, the volume of the cylinder is [tex]229612.5\ cm^3[/tex].
Answer:
229612.5
229613
Step-by-step explanation:
A cell reproduces by doubling every hour. If you start with a single cell, how many will you have in 24 hours?
Answer: 4 cells.
Step-by-step explanation:
Answer:
In 24 hours you will have 16777216 cells
Step-by-step explanation:
So if we know that we start of with one cell and each hour each cell keeps on doubling then we can find out how much cell there will be in 24 by doing th following.
1 x 2 = 2 (the number of cells after 1 hour)
2 x 2 = 4 (the number of cells after 2 hours)(in order to obtain this we need to multiply the number of cells from the previous hour by 2, and we do this process repeatedly till we get the number of cell after 24 hours). So techencly the number of cells after 24 hours will be equal to
1 x [tex]2^{24}[/tex]
And so the number of cells after 24 hours will be....
1 x [tex]2^{24}[/tex] = 1 x 16777216 = 16777216

Slope: -2/3
Y-intercept: (0, 9)
Equation: y = -x + 9
3 blocks away: 6 visits
Step-by-step explanation:
Calculate slope from point (1, 8) to point (3, 7) on the line.
The y-intercept is where the line meets the y-axis.
The equation took a bit of guessing, but the -x is the y = x line, but reversed. 9 is the y-intercept.
Check the point on the line where x = 3.

Answer:
Part a y=10.99+1.25x
Part B 14.74
Answer:
Part A) 10.99 + x = y
Part B) 14.74$
Step-by-step explanation:
In part A, you add the number of toppings to the pizza. Making the expression: Pizza Cost + Topping = Total Amount.
In part B, you do 1.25*3 = 3.75 (Cost of 3 toppings) + 10.99 (Cost of the pizza) = 14.74$

B. C(n)= 0.75n-0.25
C. C(n)= 1.0n
D. C(n)= 0.75n
Which one is it?
Answer: B. C(n)=0.75n-0.25
Hope these helped u :)
Step-by-step explanation:
Answer: I believe it's B because 1 candy bar=0.75 but there's a $0.25 percent off so I think 0.75n-0.25 would be the right answer

0.1(0.5m+6)=2
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.

A. The solution is (−2,−3)
B. infinitely many solutions
C. no solution
D. The solution is (−3,−2)
9514 1404 393
Answer:
D. (-3, -2)
Step-by-step explanation:
The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.
Using (x, y) = (-2, -3):
x = y -1 ⇒ -2 = -3 -1 . . . . False
Using (x, y) = (-3, -2):
x = y -1 ⇒ -3 = -2 -1 . . . .True
2x = 3y ⇒ 2(-3) = 3(-2) . . . . True
The solution is (-3, -2).
__
If you'd like to solve the set of equations, substitution for x works nicely.
2(y -1) = 3y
2y -2 = 3y . . eliminate parentheses
-2 = y . . . . . . subtract 2y
x = -2 -1 = -3
The solution is (x, y) = (-3, -2).

Solve for a.
ab + c = d
The answer Answer is:
a=d-c/b
a) solve x + x + x = 54
b) solve y/5 = 7
c) solve 4t+6=24
Answer:
a) x = 18
b) y = 35
c) t = 4.5
Step-by-step explanation:
a) x + x + x = 54
3x = 54
x = 54 ÷ 3
x = 18
b) y/5 = 7
(y/5) × 5 = 7 × 5
y = 35
c) 4t + 6 = 24
4t +6 - 6 = 24 -6
4t = 18
4t ÷ 4 = 18 ÷ 4
t = 4.5
Answer:
a) 18
b) 35
c) -4.5
Step-by-step explanation:
a) x + x + x = 54
combine like terms.
3x = 54
Divide both sides by 3.
x = 18
b) y / 5 = 7
Multiply both sides by 5.
y = 5 × 7
y = 35
c) 4t + 6 = 24
Take 6 to right side.
4t = 24 - 6
4t = -18
Divide both sides by 4.
t = -4.5

Which model represents 2.36 ÷ 4? A. Three groups of three tenths and four hundredths B. Three groups of five tenths and nine hundredths C. Four groups of three tenths and six hundredths D. Five groups of five tenths and nine hundredths
Answer:
Five groups of five tenths and nine hundredths
Step-by-step explanation:
Mathematically;
2.36 divided by 4 = 0.59
So we want to select from the options, the best representation of this
That will be
0.5 + 0.09
so our answer is 5 groups of five tents and nine hundredths
The model which represents 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths
We must perform the division 2.36 ÷ 4 first so that we have;
2.36 ÷ 4 = 0.59The result, 0.59 can then be written in words as; Five tenths and 9 Hundredths.
Ultimately, the model. which represents the expression 2.36 ÷ 4 is; Choice D: Five groups of five tenths and nine hundredths.
