Uncle Drew averaged 5.6 points per minute during that 5-minute game.

To find the average number of points Uncle Drew scored per minute during the 5-minute game, we divide the total number of points scored by the number of minutes played.

Given that Uncle Drew scored 28 points in 5 minutes, we divide 28 by 5:

[tex]\[ \text{Average points per minute} = \frac{28}{5} \]\[ \text{Average points per minute} = 5.6 \][/tex]

Final answer:

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes. The probability is 1/4 or 0.25.

Explanation:

To find the probability that the product of two standard dice is prime or ends in a 5, we need to count the favorable outcomes and divide it by the total number of possible outcomes.

To have a prime product, the possible combinations are: (2,2), (2,3), (2,5), (3,2), (3,3), (3,5), (5,2), (5,3), (5,5)

To have a product that ends in 5, the possible combinations are: (1,5), (2,5), (3,5), (4,5), (5,5), (6,5).

The total number of favorable outcomes is 9.

When two dice are rolled, there are 36 total possible outcomes (6 possible outcomes for the first die multiplied by 6 possible outcomes for the second die).

Therefore, the probability that the product is prime or ends in a 5 is 9/36, which simplifies to 1/4 or 0.25.

The area of the circle is approximately [tex]\(69.46 \, \text{mm}^2\)[/tex] and the circumference is approximately [tex]\(53.49 \, \text{mm}\).[/tex]

To find the area A and circumference C of a circle given its diameter d, we can use the following formulas:

1. Area A of a circle:

[tex]\[ A = \pi \times \left(\frac{d}{2}\right)^2 \][/tex]

2. Circumference C of a circle:

[tex]\[ C = \pi \times d \][/tex]

Given that the diameter d is 17 mm, we can plug this value into the formulas to find the area and circumference.

1. Area A of the circle:

[tex]\[ A = \pi \times \left(\frac{17}{2}\right)^2 \]\[ A = \pi \times \left(\frac{17}{2}\right) \times \left(\frac{17}{2}\right) \]\[ A = \pi \times \frac{17 \times 17}{4} \]\[ A = \pi \times \frac{289}{4} \]\[ A = \frac{289}{4} \pi \][/tex]

[tex]\[ A \approx 69.46 \, \text{mm}^2 \][/tex]

2. Circumference (\(C\)) of the circle:

[tex]\[ C = \pi \times 17 \]\[ C = 17\pi \][/tex]

[tex]\[ C \approx 53.49 \, \text{mm} \][/tex]

r^9- r^3

answer:

r^6

Which expression is equivalent to [tex]r^9/r^3[/tex] ?  The correct answer is b) [tex]r^6[/tex].

To simplify the expression [tex]r^9/r^3[/tex], we need to apply the rule of exponents. When dividing two terms with the same base, you can subtract the exponents.

In this case, both [tex]r^9[/tex] and [tex]r^3[/tex] have the same base 'r', so we subtract the exponent of [tex]r^3[/tex] from the exponent of [tex]r^9[/tex].

[tex]r^9/r^3[/tex] = [tex]r^{9-3}[/tex] = [tex]r^6[/tex].

In this problem, we are given the expression [tex]r^9/r^3[/tex] and we need to find an equivalent expression for it. To do that, let's understand the rules of exponents.

In general, when you have a term raised to a certain power and you divide it by the same term raised to a different power, you can simplify it by subtracting the exponents. For example, [tex]a^m / a^n = a^{m-n}[/tex].

Now, looking at our expression, [tex]r^9/r^3[/tex], we notice that both terms have the same base 'r'. According to the rule mentioned above, we can simplify the expression by subtracting the exponent of r3 from the exponent of [tex]r^9[/tex].

[tex]r^9/r^3[/tex] = [tex]r^{9-3}[/tex] = [tex]r^6[/tex].

So, the expression [tex]r^9/r^3[/tex] is equivalent to [tex]r^6[/tex]. This means that when you have a term raised to the power of 9 and you divide it by the same term raised to the power of 3, the result is the term raised to the power of 6.

In conclusion, the correct answer is b) [tex]r^6[/tex], as it represents the equivalent expression to [tex]r^9/r^3[/tex] after applying the rules of exponents.

3. Real zeros: [tex]x = -2[/tex]

Complex zeros: [tex]x_{2,3}=-3\pm 2i[/tex]

Step-by-step explanation:

1. Given equation of parabola

[tex]s(t)=-16t^2+88t+48[/tex]

a) The rocket reaches its maximum height at the vertex of parabola. Find t-coordinate of the vertex:

[tex]t_v=\dfrac{-b}{2a}\\ \\=\dfrac{-88}{2\cdot (-16)}\\ \\=\dfrac{11}{4}\\ \\=2.75\ seconds[/tex]

b) The maximum height is s-coordinate of the vertex. Find it:

[tex]s\left(\dfrac{11}{4}\right)\\ \\=-16\cdot \left(\dfrac{11}{4}\right)^2+88\cdot\left(\dfrac{11}{4}\right)+48\\ \\=-121+22\cdot 11+48\\ \\=169\ feet[/tex]

2. For x – 3 to be a factor of  [tex]f(x)=6x^4-11x^3-35x^2+34x+24,[/tex] the Factor Theorem says that x = 3 must be a zero of  f(x). Check it (whether f(3)=0):

[tex]f(3)\\ \\=6\cdot 3^4-11\cdot 3^3-35\cdot 3^2+34\cdot 3+24\\ \\=6\cdot 81-11\cdot 27-35\cdot 9+102+24\\ \\=486-297-315+126\\ \\=0[/tex]

So, x = 3 is zero of the function f(x) and x - 3 is the factor of the function f(x). Rewrite the function as follows:

[tex]f(x)\\ \\=6x^4-11x^3-35x^2+34x+24\\ \\=6x^4-18x^3+7x^3-21x^2-14x^2+42x-8x+24\\ \\=6x^3(x-3)+7x^2(x-3)-14x(x-3)-8(x-3)\\ \\=(x-3)(6x^3+7x^2-14x-8)\\ \\=(x-3)(6x^3+12x^2-5x^2-10x-4x-8)\\ \\=(x-3)(6x^2(x+2)-5x(x+2)-4(x+2))=\\ \\=(x-3)(x+2)(6x^2-5x-4)\\ \\=(x-3)(x+2)(6x^2+3x-8x-4)\\ \\=(x-3)(x+2)(3x(2x+1)-4(2x+1))\\ \\=(x-3)(x+2)(2x+1)(3x-4)[/tex]

Step-by-step explanation:

This is because Neil Shot less, but made more.

I hope this helps you!

Final answer:

Neil had a better free throw percentage at approximately 62.87% compared to Avid's 60.07% by calculating the number of successful throws divided by the total attempts and multiplying by 100.

Explanation:

The question involves comparing the free throw rates of two basketball players to determine who had a better free throw percentage. To find the free throw percentage, we divide the number of successful free throws by the total number of attempts and then multiply by 100.

For Neil:

(215 free throws ÷ 342 attempts) × 100 = ~62.87%

For Avid:

(358 free throws ÷ 596 attempts) × 100 = ~60.07%

Neil had a better free throw percentage than Avid as 62.87% is higher than 60.07%.

Answer:

Biker will catch the cyclist after 2 hr and 40 min.

Step-by-step explanation:

Given:

Speed of Bicyclist = 20 km/h

Travelling time = 4 hrs

∴ Distance = Speed × Time = [tex]20\times4=80 \ km[/tex]

Also he rest for 1 hr.

So we can say that, after 5 hrs Bicyclist is 80 km ahead when the biker Started.

Now Biker rate is given 50 km/h

And Bicyclist rate is 20 km/h

So, for each hour, biker advances 50 - 20 = 30 kilometers

now bicyclist distance is 80 km

and biker advances 30 per hour.

Therefore to catch up bicyclist at 80 km i.e time taken to reach 80 km with 30 km rate per hour.

Time = [tex]\frac{80}{30}=2 \frac{2}{3} h[/tex]

Hence, Biker will catch the cyclist after 2 hr and 40 min.

Answer:

Andre is taller.

Step-by-step explanation:

I assume Andre's height is 1.7 m.

Let's convert Andre's height to cm.

1 m = 100 cm

1.7 m = 1.7 * 1 m = 1.7 * 100 cm = 170 cm

Andre is 170 cm tall. Diego is 165 cm tall.

Since 170 cm > 165 cm, Andre is taller.

1.7 m = 170 cm

170 cm > 165 cm

Andre > Diego

Answer:

x=2000

Step-by-step explanation:

The conditions state, being x, N, M positive integers:

[tex]x-64=N^2[/tex]         [1]

[tex]x+25=M^2[/tex]       [2]

Subtracting the [1] from [2]

[tex]89=M^2-N^2=(M-N)(M+N)[/tex]

Since 89 has no other prime factors except 1 and itself, we can write

[tex](M-N)(M+N)=(1)(89)[/tex]

[tex]M+N=89[/tex]

[tex]M-N=1[/tex]

This system of equations results in [tex]M=45, N=44[/tex]

Replacing in [1] or [2] results

[tex]x=2000[/tex]

Proof:

[tex]2000-64=1936 =44^2[/tex]

[tex]2000+25=2025=45^2[/tex]

To obtain y - x from x - y, add 2y - 2x to x - y which simplifies to y - x.

To transform x - y into y - x, we need to add something that effectively swaps x and y while also changing the sign of both variables. This is a classic example of using the property that A - B is the same as A + (-B). Applying this to our expression, if we add 2y to x - y, we'll get x + y. But, we need y - x, not x + y. So, we need to subtract x twice. Once to cancel out the original x, and a second time to create the negative x in the desired expression. Essentially, we add -2x to our new expression, x + y. So, the final answer is (x - y) + 2y - 2x, which simplifies to y - x.

Answer:

A) y=-3/2x+5/2

Step-by-step explanation:

y=mx+b

6x+4y=10

4y=10-6x

4y=-6x+10

y=-6/4x+10/4

simplify

y=-3/2x+5/2

The equation 6x + 4y = 10 written in slope-intercept form is y = -3/2x + 5/2.

The equation Y = mx + b exists in the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m exists the slope of the line and b exists the intercept. X and y describe the distance of the line from the x-axis and y-axis, respectively. The value of b exists equivalent to y when x = 0, and m indicates how steep the line exists.

Let the equation be, 6x + 4y = 10

Simplifying the above equation we get

4y = 10 - 6x

4y = -6x + 10

y=-6/4x + 10/4

simplify

y = -3/2x + 5/2.

Therefore, the correct answer is option A. y= -3/2x + 5/2.

Step-by-step explanation:

Answer:

The answer is 48 games out of 84.

Step-by-step explanation:

So first we go through a step by step process.

We have a problem set up that looks something like this.

8/14 = ?/84

Step 1:

So we will first divide 84 by 14, giving us 6.

Step 2:

So 14x6 is equal to 84. Now we have to multiply the top half of the equation by 6. This is 8x6 giving us 48.

Step 3:

Now we substitute the ? with the 48. In the end if playing 84 games the hockey team would win 48 at the rate it was going.

Li incorrectly added 64 and 17 to get 71, but the correct sum is 81 pages. This mistake was likely due to adding the tens place incorrectly.

Li made a mistake in her addition. When adding 64 and 17, she erroneously stated that the sum was 71 pages. To clarify what Li did wrong, we can simply add the two numbers together properly.

Start by adding the ones place: 4 (from 64) + 7 (from 17) equals 11. Write down 1 and carry over the 1 to the tens place.

Next, add the tens place: 6 (from 64) + 1 (from 17) + 1 (carried over) equals 8.

Combine the numbers in the tens and ones place to get 81.

Therefore, the correct sum of 64 and 17 is 81 pages. This is how many pages Li read in all.

Final answer:

To find out how much was spent on fresh flowers, 10% of the monthly budget of $5,000 was calculated, resulting in $500 spent on fresh flowers.

Explanation:

If the monthly budget for the front of the house is $5,000, and you spent 10% of the budget on fresh flowers, you can calculate the amount spent on fresh flowers by finding 10% of $5,000. To do this, you simply multiply the total budget by the percentage (expressed as a decimal).

To express 10% as a decimal, you divide 10 by 100, which gives 0.10. Next, multiply the monthly budget by this decimal:

0.10 × $5,000 = $500

Therefore, you spent $500 on fresh flowers.
