do 252/448 and 36/64 form a proportion?
Answer:
252/448 and 36/64 form a proportion
Step-by-step explanation:
The easiest way to do this is to let 252/448 = 36/64
Then cross multiply to get 252(64) = 36(448)
16128 = 16128
Since the two products are equal, then 252/448 and 36/64 form a proportion. If the the two products were unequal, then the two fractions would NOT form a proportion.
A particle moves along a line so that its position at any time t > 0 is given by the function s(t) = - t3 + 7t2 - 14t +8 where s is measured in meters and t is measured in seconds. Find the displacement during the first 5 seconds.
Answer:
s(5) = -12
Step-by-step explanation:
s(t) = - t³ + 7t² - 14t +8
Find the displacement during the first 5 seconds.
When t = 5
s(t) = - t³ + 7t² - 14t +8
s(5) = -5³ + 7(5)² - 14(5) + 8
= -125 + 7(25) - 70 + 8
= -125 + 175 - 70 + 8
= -12
s(5) = -12
Find the volume of the cone.
h= 10 cm
Q
r = 3cm
Answer:
Step-by-step explanation:
Volume=[tex]\frac{1}{3} \pi (3^{2} )(10)[/tex]
=[tex]30\pi[/tex] cm³
Answer:
94.2cm³
Step-by-step explanation:
(see attached for reference)
the volume of a right cone is given as
V = (1/3) π r² h
where,
π = 3.14
r = given as 3 cm
h = given as 10 cm
hence,
V = (1/3) π r³ h
= (1/3) (3.14) (3²)(10)
= 94.2cm³

Type the correct answer in the box.
The product of (3 - 4) and (blank)
is 25.
Answer:
-25
Step-by-step explanation:
Since product mean multiply, we multiply (3-4) and (blank), which we'll call "n".
(3-4)n = 25
subtract in parentheses
(-1)n = 25
remove parentheses
-1n = 25
swap signs
n = -25

A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2
= 12 x 10 / 2
= 120 / 2
= 60 cm2
Area of rectangle = l x b
Given
l = 12
b = 10
hence
area of rectangle = l x b
= 12 x 10
= 120 cm2

Answer:

Step-by-step explanation:
5x+3y=9
subtract 5x from each side
3y=-5x+9
divide 3 from each side
y=-5/3x+3
Answer:
The third option. y = −5 / 3x + 3
Step-by-step explanation:
Let's solve for y.
5x + 3y = 9
Step 1: Add -5x to both sides.
5x + 3y + −5x = 9 + −5x
3y = −5x + 9
Step 2: Divide both sides by 3.
3y / 3 = −5x + 9
3y = −5 / 3x + 3
Answer:
y = −5 / 3x + 3

Students bought 32 copies of Amazing Science for a total cost of $95.36 and 32 copies of Sci-Fi for a total cost of $110.40. If each student bought 1 copy of each magazine, how much did each student spend?
Answer:
$6.43
Step-by-step explanation:
Students bought 32 copies of Amazing Science for a total cost of $95.36 and 32 copies of Sci-Fi for a total cost of $110.40. If each student bought 1 copy of each magazine, how much did each student spend?
For Amazing science:
$95.36 = 32 copies
Therefore,
1 copy = 1 student
Hence:
32 student = $95.36
1 student = x
Cross Multiply
32x = $95.36
x = $95.36/32
x = $2.98
For Sci fi
$110.40 = 32 copies
Therefore,
1 copy = 1 student
Hence:
32 student = $110.40
1 student = x
Cross Multiply
32x = $110.40
x = $110.40/32
x = $3.45
Hence, each student spent
$2.98 on Amazing Science and $3.45 on Sci Fi magazines.
The total amount they spent
= $2.98 + $3.45
= $6.43
Therefore, If each student bought 1 copy of each magazine, each student spent $6.43

year?
a) In the sketch box, draw a diagram to represent this
situation.
b) In the answer box, write a simplified equation to
represent this situation. Use "y" to represent the
amount of snowfall this year. Your equation should use
decimals.

pls mark brainliest
We can conclude that -
The amount snowed this year is 63 inches.A simplified equation to represent this situation -y = 45 + {40% of 45}What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that it snowed 40% more this year than it did last year. It
snowed 45 inches last year.
{ 1 } -
The amount snowed this year would be -
{x} = 45 + (40% of 45)
{x} = 45 + (40/100 x 45)
{x} = 45 + 18
{x} = 63
{ 3 } -
A simplified equation to represent this situation -
y = 45 + {40% of 45}

Jon is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by h(t)=5+25t-16t^2, where t is the time in seconds.
a) How much time will pass before Jon hits the ball? (round to the nearest tenth of a second)
b) What is the time in which the maximum height the ball attains? ( to the nearest hundredth of a second)
Answer: A= 1.60 sec
And I am not sure if B is correct, but I got 14.77 ft.
Step-by-step explanation:
Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
We have Jon who is hitting baseballs. When he tosses the ball into the air, his hand is 5 feet above the ground. He hits the ball when is falls back to a height of 4 feet. The height of the ball is given by -
h(t) = 5 + 25t - 16t²
where [t] is the time in seconds.
[A] -
At h = 4ft, we can write -
4 = 5 + 25t - 16t²
- 16t² + 25t + 1 = 0
On solving, we get -
t = 1.602 seconds
[B] -
We have -
h(t) = 5 + 25t - 16t²
For maximum height -
dh/dt = 0
d/dt(5 + 25t - 16t²) = 0
0 + 25 - 32t = 0
32t = 25
t = 25/32
t = 0.79 seconds
Therefore -
t = 1.602 seconds will pass before Jon hits the ball.At t = 0.79 seconds the ball attains maximum height.To solve more questions on Equation Modelling, visit the link below -

the approximate number of blood cells B passing through an animal's major artery each millisecond is given by B=17m^((4)/(3))where m is animal's mass in kilograms. Find the number of blood cells passing through a 243 kg bear's major artery each millisecond
Given:
The approximate number of blood cells B passing through an animal's major artery each millisecond is given by
[tex]B=17m^{\frac{4}{3}}[/tex]
Where, m is animal's mass in kilograms.
To find:
The number of blood cells passing through a 243 kg bear's major artery each millisecond.
Solution:
We have,
[tex]B=17m^{\frac{4}{3}}[/tex]
Putting m=243, we get
[tex]B=17(243)^{\frac{4}{3}}[/tex]
[tex]B=17(1516.381107)[/tex]
[tex]B=25778.4788191[/tex]
[tex]B\approx 25778[/tex]
