Answer:
24 pounds of apples for $60
about 3 apples per pound
about 72 apples for $60
Step-by-step explanation:
$15 times 4 = $60, therefore 6 pounds times 4 = 24 pounds
5 out of 16 ounces equals about 3 apples per pound
24 pounds, with 3 apples in each pound, equals 72

Natalee wanted to demonstrate the volume of a square pyramid. To do this, she took a hollowed out pyramid that has a base of 25 square inches and a height of 5 inches and filled it with water. She then dumped this water into a hollowed out cube that has a volume of 125 cubic inches. Enter the amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube
Answer:
The answer is below
Step-by-step explanation:
Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:
Number of times = volume of cube / volume of pyramid
The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in
Volume of square pyramid = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = 125 in³ / 65.1 in³ = 1.92
The amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube is 1.92.
What is volume?The capacity of a container of any shape is called the volume.
Natalee transferred water from a square pyramid to a cube. Then,
Given is the perimeter of the pyramid base = 25 in
So, the length of one side of the base b= 25 / 4 = 6.25 in
Volume of square pyramid = b² × (h/ 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = volume of cube / volume of pyramid
Number of times = 125 in³ / 65.1 in³ = 1.92

What are trigonometric relations?
Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles
The six trigonometric functions are sin , cos , tan , cosec , sec and cot
Let the angle be θ , such that
sin θ = opposite / hypotenuse
cos θ = adjacent / hypotenuse
tan θ = opposite / adjacent
tan θ = sin θ / cos θ
cosec θ = 1/sin θ
sec θ = 1/cos θ
cot θ = 1/tan θ
Given data ,
Let the angle be represented as A
Now , the value of A is
A = arc cos ( 0.21 )
The value of arc cos ( 0.21 ) = 1.35922137 rad
The value of 1 rad = ( 180°/π ) degrees
So , 1.35922137 rad = 1.35922137 ( 180°/π ) degrees
On simplifying the equation , we get
The value of arc cos ( 0.21 ) = 77.8776478 degrees
Rounding to the nearest hundredth , we get
The value of arc cos ( 0.21 ) = 77.88 degrees
Hence , the measure of arc cos ( 0.21 ) is 77.88°

Write an equation of the line that passes through (7.10) and is perpendicular to the line y =
Answer:
10 = -2(7) +24
Step-by-step explanation:
or
y = -2 (7) +24
first, we find the negative reciprocal of the slope of the first equation.
1/2 = -2/1 = -2
So the slope for the new equation will be -2
y = -2x+b
Now we know it will pass through the point (7,10)
So the x coordinate will become x, and the y coordinate will become y
10= -2(7) +b
-2 x 7 = -14 + b = 10
-14 -10 = -24
so
b = 24
because
-14 + 24 = 10
So our final equation(s) are
y = -2(7) +24
or
10 = -2 (7) + 24
The local ice cream shop surveyed their costumers to see wich flavor of ice cream is most popular.125 people chose chocolate as their favorite flavor,wich represents 25% of the costumers surveyed.How many total costumers were surveyed?
Answer: The total costumers were surveyed = 500
Step-by-step explanation:
Let x = total costumers were surveyed.
Given : 125 people chose chocolate as their favorite flavor, which represents 25% of the costumers surveyed.
25% of x = 125
[tex]\Rightarrow\ \dfrac{25}{100}\times x = 125\\\\\Rightarrow\ \dfrac{1}{4}x=125\\\\\Rightarrow\ x=125\times4\\\\\Rightarrow\ x= 500[/tex]
Hence, the total costumers were surveyed = 500

if an object has a density of 6.g/mL and you put it into water, will it sink or float?
Step-by-step explanation:
If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume. If two objects take up the same volume, but have one has more mass, then it also has a higher density.

Layla emptied out her change jar to buy a new binder for school. She found 147 coins consisting of dimes and nickels that totaled $11.65. Write a system of equations that could be used to determine how many dimes, d, and how many nickels, n, Layla had in her change jar.
Answer:
d + n = 147
0.10d + 0.05n = 11.65
d = 86, n = 61
Step-by-step explanation:
Let
Number of dimes = d
Number of nickels = n
Total coins = 147
Total value = $11.65
d + n = 147 (1)
0.10d + 0.05n = 11.65 (2)
From (1)
d = 147 - n
Substitute d = 147 - n into
0.10d + 0.05n = 11.65
0.10(147 - n) + 0.05n = 11.65
14.7 - 0.10n + 0.05n = 11.65
- 0.10n + 0.05n = 11.65 - 14.7
-0.05n = -3.05
n = -3.05 / -0.05
= 61
n = 61
Substitute n = 61 into
d + n = 147
d + 61 = 147
d = 147 - 61
d = 86
how to solve using Substitution or Elimination?
y=3x-1
y=2x+2
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
So, the solution is x = 1 and y = 4 {or: (1, 4)}Figure ABCD has vertice A (5,9) B (7,5) C (5,1) D (3,5)
