Answer:

Kyle can jump rope the most times per minute.  

Step by step explanation:

We have been given that Daren can jump rope 116 times in 2 minutes.

So number of rope jumps done by Daren in 1 minute will be:

[tex]\text{Unit rate of Jump rope done by Daren}=\frac{116\text{ times}}{2\text{ minute}}[/tex]

[tex]\text{Unit rate of Jump rope done by Daren}=58\frac{\text{ times}}{\text{ minute}}[/tex]

Therefore, Daren jumps rope 58 times per minute.

We have been given that Kyle can jump rope 240 times in 4 minutes.

So number of rope jumps done by Kyle in 1 minute will be:

[tex]\text{Unit rate of Jump rope done by Kyle}=\frac{240\text{ times}}{4\text{ minute}}[/tex]

[tex]\text{Unit rate of Jump rope done by Kyle}=60\frac{\text{ times}}{\text{ minute}}[/tex]

Therefore, Kyle jumps rope 60 times per minute.

We have been given that Marissa can jump rope 225 times in 5 minutes.

So number of rope jumps done by Marissa in 1 minute will be:

[tex]\text{Unit rate of Jump rope done by Marissa}=\frac{225\text{ times}}{5\text{ minute}}[/tex]

[tex]\text{Unit rate of Jump rope done by Marissa}=45\frac{\text{ times}}{\text{ minute}}[/tex]

Therefore, Marissa jumps rope 45 times per minute.

As Kyle jumps rope 60 times per minute, which is greater than jumps rope done by Daren and Marissa, therefore, Kyle can jump rope the most times per minute.

Answer:

[tex]t\leq 70[/tex]

Step-by-step explanation:

The team spends 20 minutes running laps

At least 15 minutes discussing plays.

Practice lasts one hour and 45 minutes.

We know that 1 hour = 60 minutes, so the practice lasts,

60+45= 105 minutes.

The team spends a total of [tex]20+15=35[/tex] minutes  in running and discussion.

So the time remaining to work on other drills is,

[tex]t\leq 105-35[/tex]

Answer:

P ( blue ) =  1/4

P ( white ) =  5/12

P ( red ) = 1/3

P ( not red ) =  2/3

Step-by-step explanation:

To find the probability of a marble being chosen,  it is the number of that color over the total

We need to find the total number of marbles

4 red+ 5 white+3 blue = 12 marbles

P ( blue ) = 3 blue / 12 total = 3/12 = 1/4

P ( white ) = 5 white / 12 total = 5/12

P ( red ) = 4 red/ 12 total = 4/12 = 1/3

How man marbles are not red

total marbles - red marbles = 12-4 = 8

8 marbles are not red

P ( not red ) = 8 not red / 12 total = 8/12 = 2/3

Answer:

5y^3

Step-by-step explanation:

Find what is common to all the terms

5y^5 = 5 * y*y*y*y*y

35y^4 = 5*7*y*y*y*y

15y^3 = 3*5*y*y*y

Answer:

The bowling alley should rent 150 pairs of shoes and should about 75 games per day in order to reach a goal of 300 dollars.

Step-by-step explanation:

It's an arithmetic sequence:

[tex]a_1=4;\ a_2=10;\ a_3=16;\ a_4=22;\ ...[/tex]

The explicit rule:

[tex]a_n=a_1+(n-1)d[/tex]

[tex]d=a_{n+1}-a_n\to d=a_2-a_1=a_3-a_2=a_4-a_3=...[/tex]

[tex]d=10-4=16-10=22-16=6[/tex]

Substitute:

[tex]f(n)=4+(n-1)(6)=4+6n-6=6n-2[/tex]

The explicit rule for the arithmetic sequence 4, 10, 16, 22, ... is aₙ = 4 + (n - 1) x 6, where aₙ is the nth term of the sequence.

The given sequence is arithmetic, which means that it increases by the same amount each time. To find an explicit rule for the sequence, we should determine the common difference and use the formula for an arithmetic sequence, which is aₙ = a₁ + (n - 1)d, where an is the nth term, a1 is the first term, n is the number of the term in the sequence, and d is the common difference between terms.

In the sequence 4, 10, 16, 22, ..., the first term a1 is 4, and the common difference is 6 (since 10 - 4 = 16 - 10 = 22 - 16 = 6). Therefore, the explicit rule for the nth term of the sequence is aₙ = 4 + (n - 1) x 6.

After drinking 24 gallons out of the required 40 gallons, the elephant needs at least 4 more tanks of water as each tank holds 4 gallons. The inequality representing this is x ≥ 4.

The student needs to calculate how many more tanks of water an elephant needs to drink to reach its daily requirement of at least 40 gallons if each tank contains 4 gallons of water. To start, we determine how much water the elephant still needs after drinking 24 gallons:

Required daily water - Water already consumed = Remaining water needed

40 gallons - 24 gallons = 16 gallons

Next, we find out how many tanks are needed for the remaining 16 gallons, knowing that each tank holds 4 gallons:

Number of tanks needed = Remaining water needed / Water per tank

Number of tanks needed = 16 gallons / 4 gallons per tank

Number of tanks needed = 4 tanks

Since the elephant needs at least 40 gallons, it will need at least 4 more tanks of water. However, since we're writing this as an inequality, we want to express that the elephant may drink more. Hence, the inequality will be:

x ≥ 4

Answer:

[tex]f(x) = -x^2 +x +1[/tex]

Step-by-step explanation:

Quadratic equation is in the form of

[tex]f(x)= ax^2+bx+c[/tex]

When the value of 'a' is positive then the graph opens up

When the value of 'a' is negative  then the graph opens down

When the graph opens up then the vertex is minimum.

When the graph opens down then the vertex is maximum.

y intercept is the value of 'c'

[tex]f(x) = 2x^2 - 4x - 3[/tex], a=2 the graph opens up

[tex]f(x) = -x^2 +x +1[/tex], a=-1 the graph opens down. So the vertex is maximum. Y intercept is +1. y intercept is positive.

[tex]f(x) = -2x^2 +3x - 1[/tex], a=-2 the graph opens down. So the vertex is maximum. Y intercept is -1. y intercept is negative.

[tex]f(x) = 2x^2 - 4x - 3[/tex], a=2 the graph opens up

The correct answer for dividing [tex](a^{2n} - a^n - 6) by (a^n + 8)[/tex] is indeed:

[tex](a^n - 9) + (-78)/(a^n + 8).[/tex]

Let's divide the given polynomials:

[tex]\frac{a^{2n -a^n -6}}{a^n +8}[/tex]

Here's the breakdown of the solution:

Factoring: We can factor the numerator [tex](a^{2n} - a^n - 6)[/tex] using difference of squares:

[tex](a^{2n} - a^n - 6) = (a^n)^2 - (a^n) - 6 = (a^n + 2)(a^n - 3)[/tex]

Division: Now, we can divide the factored numerator by the denominator:

[tex][(a^n + 2)(a^n - 3)] / (a^n + 8) = (a^n + 2) - [(a^n + 8) * (a^n - 3)] / (a^n + 8) = (a^n + 2) - (a^n - 3) = a^n - 9[/tex]

Remainder: Since the degree of the numerator is less than the degree of the denominator, we get a non-zero remainder.

This remainder is obtained by dividing the constant term (-6) in the numerator by the constant term (8) in the denominator, resulting in [tex]-78/(a^n + 8).[/tex]

Therefore, the final answer is [tex](a^n - 9) + (-78)/(a^n + 8)[/tex], with a quotient of [tex](a^n - 9)[/tex] and a non-zero remainder of [tex](-78)/(a^n + 8).[/tex]

Answer:

12x² -27x + 13

Step-by-step explanation:

First of all, expand the first two brackets and put the correlating values near each other:

10x² + 5x² -19x -8x -2 +13

10x² + 5x² = 15x²

-19x + - 8x = -27x

-2 + 13 = 11

15x² - 27x + 11

Now, subtract the values inside the third bracket:

15x² - 3x² = 12x²

11 - -2 = 11 + 2 = 13

So the end result is:

12x² -27x + 13

1 yard is 36 inches  

so 5 yards are 180 inches  

1 hour is 60 minutes  

so in 60 minutes she paints 180 inches  

or in 1 minute she paints 3 inches

13x2. 13 is how much the cds cost. 2 is how many she is buying. 13x2 is 26. Check 13+13=26.26-13=13.

Hope this helps!

Since it's 48 out of 160 and you're trying to find the percentage out of 100, this particular formula would look like this: 48/160=x/100.

Then you cross multiply: 48x100=4800

Then you take the result of that and divide it by the total number of houses. 4800/160=30

30% of the houses are brick.

Answer:

0.1071

Step-by-step explanation:

Given

Total number of students=8

Boys=2

Girls=6

When we are picking a group from population we use combinations to calculate sample space and for event

So if a group of 5 has to be picked from 8 students

ⁿC_k=  n!/(k!)(n-k)!

C_(n,k)=  n!/(k!)(n-k)!

Here n=8 and k=5

C_8,5=  8!/(5!)(8-5)!

This will give us:  

C_8,5=56

And if we have to pick only girls:

C_6,5=  6!/(5!)(6-5)!

=6

The probability of picking all girls:

=6/56

=0.1071

Answer:

The budget in 2010 is $4453.10915 billion

Step-by-step explanation:

We are given exponential function as

[tex]f(t)=39.4e^{0.0787932t}[/tex]

where t is the time in years since 1950

now, we can find time in 2010

t=2010-1950=60

now, we can plug t=60

and we get

[tex]f(60)=39.4e^{0.0787932\times 60}[/tex]

we get

[tex]f(60)=4453.10915[/tex]

So, the budget in 2010 is $4453.10915 billion

Question:

line x + 2y = 0 is end side of angle θ

and cos θ < 0

Answer: sin θ = √5/5

Step-by-step explanation:

cos θ < 0 means x < 0

Line is y = -x/2, slope -1/2

Line intersects unit circle when x^2+y^2=1

x^2 + (-x/2)^2 = 1

x^2 + x^2/4 = 1

5x^2/4 = 1

x = -√(4/5) = -2√(1/5) = -2√5/5

y = √5/5

x^2 = 4/5, y^2 = 1/5

sin θ is y value at intersection of line and unit circle, √5/5

In this exercise we have to use the given equation and thus calculate the intersection value:

[tex]sin (\theta) = \sqrt{5/5}[/tex]

So knowing that you were informed:

Line x + 2y = 0 is end side of angle θ and  cos θ < 0 means x < 0.  Line is y = -x/2, slope -1/2 and the  Line intersects unit circle when :

[tex]x^2+y^2=1\\x^2 + (-x/2)^2 = 1\\x^2 + x^2/4 = 1\\5x^2/4 = 1\\x = -\sqrt{4/5} = -2\sqrt{1/5} = -2\sqrt{5/5}\\y = \sqrt{5/5}\\x^2 = 4/5, y^2 = 1/5[/tex]

[tex]sin(\theta)[/tex]  is y value at intersection of line and unit circle, [tex]\sqrt{5/5}[/tex]

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0 or (0,y))

You know m = 2, so you can plug it into the equation

y = 2x + b

To find "b", plug in the point (3, -2) into the equation

y = 2x + b

-2 = 2(3) + b

-2 = 6 + b

-8 = b

y = 2x - 8

The slope-intercept form:

[tex]y=mx+b[/tex]

m - slope

b - y-intercept

We have the slope m = 2 and the point (3, -2) → x = 3 and y = -2.

Substitute:

[tex]-2=(2)(3)+b[/tex]

[tex]-2=6+b[/tex]      subtract 6 from both sides

[tex]-8=b\to b=-8[/tex]

Substitute to the equation y = mx + b:

60 - 45.95 = 14.05

Seeing as this is the amount, she can spend any amount up to and including 14.05, so we need an equal to or smaller than sign:

Let x be the value of the object:

[tex]x \leq 14.05[/tex]

Answer:

133*3+90*3+30*p

Step-by-step explanation:

add all that up then divide it by three

Answer:

p=43°

Step-by-step explanation:

We know that the sum of angles inside the triangle is 180 degree

One angle is P, we find other two angles

Angles in a straight line is 180 degree.

angle adjacent to 133 is 180-133=47

angle adjacent to 90 is 180-90=90

To find out P, we add all the angle and make it equal to 180 degree

p + 47+90= 180

p+137= 180

Subtract 137 on both sides

p=43°

Answer:

1.A. 88.89

2.B.6.3%

3.C.64.92%

Step-by-step explanation:

1.[tex]\frac{8}{9}=0.8888[/tex]

to covert it into percentage multiply it with 100

then it becomes 88.888

rounding off to the nearest hundred it becomes 88.89

2. to convert into percentage multiply it with 100

therefore 0.063×100=6.3%

3. to find percentage

    %= (no of students using mobile / total no of students )× 100

       = [tex]\frac{792}{1200}[/tex]×100

       =64.918

Rounding off to nearest hundred it becomes 64.92%

Answer:

1) A. 88.89%

2) B. 6.3%

3) C. 64.92%

Step-by-step explanation:

1) After dividing 8 by 9, we get, [tex]\frac{8}{9} = 0.8889[/tex].

Now, percent of [tex]\frac{8}{9}[/tex] = 0.8889 * 100 = 88.89%

Hence, percent to nearest hundredth is 88.89%

2) We want 0.063 to be written in percent form

i.e. 0.063 * 100 = 6.3%

Hence, 0.063 into percent form is 6.3%

3) We are given that the total number of students are 1220 and the number of students that have cell phones are 792.

Therefore, the percent of students having cell phones = [tex]\frac{792}{1220} *100[/tex] = 64.92%

Hence, the percent of students having cell phones to nearest hundereth is 64.92%
