Answer:
218
Step-by-step explanation:
No. of male students = [tex]\frac{45}{100}[/tex] × 800
= 360
No. of male students that play varsity sports = [tex]\frac{30}{100}[/tex] × 360
= 108
------------------------------------------------------------------------------------------------------------
No. of female students = 800 - 360
= 440
No. of femal students who play varsity sports = [tex]\frac{25}{100}[/tex] × 440
= 110
Total no. of students who play varsity sports = 108 + 110
= 218

Answer:
third option
Step-by-step explanation:
Differentiate using the product rule
Given f(x). g(x) then the derivative is
f(x). g'(x) + g(x). f'(x) ← product rule
Given
[tex]\frac{d}{dx}[/tex](x² secx )
with f(x) = x² and g(x) = secx , then
f'(x) = 2x and g'(x) = secxtanx, thus
[tex]\frac{d}{dx}[/tex](x² secx)
= x². secxtanx + secx. 2x ← factor out xsecx from each term
= xsecx(xtanx + 2) → third option
How tall is a stack of cube shaped blocks whose volumes are 375 cube inches, 648 cube inches, and 1029 cube inches?
Answer:
The stack of blocks is 25.96 inches tall
Step-by-step explanation:
Volume of a Cube
Suppose we are given a cube of side L, the volume is calculated by:
[tex]V=L^3[/tex]
If the volume is given, the side can be found by solving for L:
[tex]L=\sqrt[3]{L}[/tex]
We know three cube-shaped blocks with volumes 375, 648, and 1029 cube inches. We'll find each of the side lengths and add them up to find the height that results when they stack up vertically.
Block 1, volume =375 cube inches:
[tex]L_1=\sqrt[3]{375}=7.21\ inch[/tex]
Block 2, volume= 648 cube inches:
[tex]L_2=\sqrt[3]{648}=8.65\ inch[/tex]
Block 3, volume =1029 cube inches:
[tex]L_3=\sqrt[3]{1029}=10.10\ inch[/tex]
Total height=[tex]7.21\ inch+8.65\ inch+10.10\ inch=25.96\ inch[/tex]
The stack of blocks is 25.96 inches tall

A cheetah ran 196 meters in 8 seconds. Select the TWO correct statements that are true if the cheetah runs at a constant rate.
. The cheetah ran 125 meters in 6 seconds.
. After 10 seconds, the cheetah will have run 245 meters.
. The cheetah ran 24.5 meters per second.
. It took the cheetah 5 seconds to run 125 meters.
Answer:
Step-by-step explanation:
Answers C, D are correct
TBh i really don't know about B because i also think its B but i'm not really that sure but it could be a possibility\
If a cheetah ran 196m is 8 seconds, then 196/8 = 24.5 meters per second.
Let’s verify all answers:
A) 24.5 x 6 = 147. 147m are ran in 6 seconds, not 125.
B) 24.5 x 10 = 245. This answer is correct!
C) We’ve establishes that a Cheetah ran 24.5 meters per second. Correct!
D) Since one minute equals 60 seconds, 24.5 x 60 = 1470. Correct!
E) 24.5 x 5 = 122.5. In this time frame, a cheetah wouldn’t run 125m.
A movie lasts 2 1/3 hours james watches 3/4 of the movie then pauses it while he eat dinner how long did he spend watching the movie. And how did you solve it.
Rewrite the length of the movie as an improper fraction.
2 1/3 = 7/3
Now multiply the length of the movie by 3/4
7/3 x 3/4 = (7 x3) / (3 x 4) = 21/12 = 1 3/4 hours

A Russian blue kitten costs $150 more than Manx kitten 9 blue kittens and 8 Manx kittens costs. Total of 14,100 write down a algebraic equation in the simplest form
Answer:
The equations 9x+8y=14100 and x = y+150 are in the simplest form.
Step-by-step explanation:
Given that:
Russian blue kitten costs $150 more than Manx kitten.
Cost of 9 blue kittens and 8 Manx kittens = $14100
Let,
x be the price of one Russian blue kitten.
y be the price of one Manx kitten.
According to given statement;
9x+8y=14100
x = y+150
Hence,

HELP I GIVE POINTS FOR THIS and brainliest Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11 to determine the 2nd term if f(1) = 4.
Answer:
The second term is 12.6
Step-by-step explanation:
Let us solve the question
∵ The recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11
∵ f(1) = 4
→ To find the 2nd term, sunstitute n by 2
∵ n = 2
∴ f(2) = 0.4 · f(2 - 1) + 11
∴ f(2) = 0.4 · f(1) + 11
→ Substitute f(1) by 4
∵ f(2) = 0.4 · 4 + 11
→ Simplify the formula
∴ f(2) = 1.6 + 11
∴ f(2) = 12.6
∴ The second term is 12.6

Show two methods for finding the quotient :
3/8 divided by 3/4
Answer:
Here's one :)
3 x 4= 12 = 1
8 x 3= 24 = 2
-by-step explanation:
The two methods of finding the quotient are flipping the divisor and then multiplying and the second one is converting the fractions into decimals and dividing them.
What are fractions?Fractions describe the part of something present out of the total amount
We know that the result of diving a fraction by a fraction is the same as multiplying that fraction by the reciprocal of the divisor.
∴ (3/8) ÷ (3/4) is,
= (3/8) × (4/3).
= 4/8.
= 1/2.
The second method is converting the fractions into decimals and then dividing them in a conventional way.
3/8 = 0.375 and 3/4 = 0.75.
∴ 0.375 ÷ 0.75 is,
= 0.5.

Find the fifth term in the geometric
sequence, given the first term and
the common ratio.
a1 = 2 and r = 3
a5 = [ ?]
The fifth term is 162 in the geometric sequence.
What is geometric sequence?The geometric sequence defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.
The nth term of a geometric progression is expressed as
Tₙ = arⁿ⁻¹
Where a is the first term, r is the common ratio
What is arithmetic sequence?A arithmetic sequence is defined as an arrangement of numbers which is particular order.
The formula to find the general term of an arithmetic sequence is,
aₙ = a₁ + (n-1)d
Given data :
First term of sequence geometric (a₁) = 2
The common ratio of geometric (r) = 3
To determine the fifth term of geometric sequence
Let the fifth term of sequence = a₅
The nth term of a geometric sequence is expressed as :
Tₙ = a₁rⁿ⁻¹
Substitute the values of n = 5, a₁ =2 and r = 3 in the formula,
T₅ = (2)(3)⁵⁻¹
T₅ = (2)(3)⁴
T₅ = (2)(81)
T₅ = 162

2. The equation x+2= v-----3x+10 is of the form x+a=v------bx+c ,where a, b, and c are all positive integers and b>1. Using this equation as a model, create your own equation that has extraneous solutions.
(a) Using trial and error with numbers for a, b, and c, create an equation of the form x+a=v-----bx+c, where a, b, and c are all positive integers and b>1 such that 7 is a solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.)
(b) Solve the equation you created in Part 2a.
(c) If your solution in Part 2b did not have an extraneous solution, revise your equation so that 7 is one solution and there is an extraneous solution. If your solution in Part 2b did have an extraneous solution, create another equation with different values of a, b, and c that also has 7 as one solution and an extraneous solution.

Find the mode of the following data. 56,34,45,65,67,56,45,36,92,73,92,45,56
====================================================
Explanation:
Original list = {56,34,45,65,67,56,45,36,92,73,92,45,56}
Sorted list = {34,36,45,45,45,56,56,56,65,67,73,92,92}
We see that 45 and 56 both occur three times each, and this is the most occurring or most frequent. So the mode is the set {45, 56}. It is possible to have more than one mode. It is also possible to not have a mode at all if each value in a list only occurs one time.

Answer:
Here is the summary:
y = 13x+5 satisfies the points (0, 5) and (-2, -21)y = -3x satisfies the points (0, 0), (-5, -15) and (-3, 9)y = x-10 satisfies the points (8, -2)Step-by-step explanation:
Given the equation
y = 13x+5y = -3xy = x-10The points which satisfy the equation y=13x+5
y = 13x+5
Checking the point (0, 5)
5 = 13(0)+5
5 = 0 + 5
5 = 5
TRUE
Checking the point (-2, -21)
-21 = 13(-2)+5
-21 = -26 + 5
-21 = -21
TRUE
The points which satisfy the equation y=-3x
y = -3x
Checking the point (0, 0)
0 = -3(0)
0 = 0
TRUE
Checking the point (-5, -15)
y = -3x
-15 = -3(-5)
-15 = -15
TRUE
Checking the point (-3, 9)
y = -3x
9 = -3(-3)
9 = 9
TRUE
The points which satisfy the equation y=x-10
y = x-10
Checking (8, -2)
-2 = 8 - 10
-2 = -2
TRUE
Therefore, from the above calculations we conclude the summary:
Here is the summary:
y = 13x+5 satisfies the points (0, 5) and (-2, -21)y = -3x satisfies the points (0, 0), (-5, -15) and (-3, 9)y = x-10 satisfies the points (8, -2)A meteorologist is measuring the temperature every 15 minutes. She notices the temperature increases by 3/4 degrees Fahrenheit between each measurements for 2 hours. What is the rate per hour of the temperature increase?
Answer:
3 °F/h
Step-by-step explanation:
The rate per hour of temperature change = change in temperature per measurement/change in time per measurement.
Now, the change in temperature per measurement is constant = 3/4 °F and the change in time per measurement is constant = 15 minutes = 15/60 h = 1/4 h.
So, rate per hour of temperature change = change in temperature per measurement/change in time per measurement
= 3/4 °F ÷ 1/4 h
= 3/4 °F × 4/h
= 3 °F/h
So, the rate per hour of temperature change is 3 °F/h
