The length of a rectangle is twice the width. the area is 256 squared. find the length and the width.

Answers

The solution is quite simple. 
First, draw a rectangle. Label two opposite sides as "w", representing the width. Label the other two sides as "2w", since the length is twice the width.
Next, write an equation. In this case, the equation would be 256=2w*w.
Simplify the equation to 2w^2=256. Divide both sides by two to get w^2=128. The width would be the square root of 128. The length would be twice that, so it would be the square root of 256. That would be 16, so the length is 16.

In a right triangle, the measure of one acute angle is 13°. What is the measure of the other acute angle?
32°
77°
90°
167°

Answers

77° is your answer.

-JJ

The sum of the angles in a triangle is always 180 degrees. In a right triangle, one angle is 90 degrees, and given that one acute angle is 13 degrees, the measure of the other acute angle is 180 - 90 - 13, which equals 77 degrees.

In the context of Euclidean geometry, we have a well-established theorem which stipulates that the sum of the angles in any triangle equals 180 degrees. Since we are dealing with a right triangle, we know that one of its angles measures 90 degrees. The question states that one acute angle measures 13 degrees. To find the measurement of the other acute angle, we subtract the known angles from 180 degrees.

180 degrees (sum of all angles in a triangle) - 90 degrees (right angle) - 13 degrees (given acute angle) = 77 degrees.

Therefore, the measure of the other acute angle is 77 degrees.

Whst is the remainder when f(x)=x^3+3x^2-10x-4 is diveded by x-3

Answers

The polynomial remainder theorem allows us to calculate the remainder when a polynomial is divided by a linear polynomial:
The remainder of f(x) divided by (x-k) equals f(k).

Thus
f(x)=x^3+3x^2-10x-4 divided by x-3
gives a remainder of
f(3)=27+3(9)-10(3)-4=27+27-30-4=20
Therefore the remainder required is 20.

The remainder when the polynomial [tex]f(x)=x^3+3x^2-10x-4[/tex] is divided by x-3 is found using the Remainder Theorem and is 20.

The remainder when a polynomial f(x) is divided by a linear divisor such as x - 3 can be found using the Remainder Theorem, which states that the remainder is simply f(3). To find the remainder for [tex]f(x)=x^3+3x^2-10x-4[/tex], we substitute x = 3 into the polynomial.

Calculate f(3):

[tex]f(3) = (3)^3 + 3*(3)^2 - 10*(3) - 4[/tex]

f(3) = 27 + 27 - 30 - 4

f(3) = 54 - 34

f(3) = 20

Therefore, the remainder when f(x) is divided by x - 3 is 20.

What is a circle?

A circle is a geometric shape, all of which points are equidistant from a fixed point called as the Centre. The centre of the circle does not lie on it. The tangents drawn from the same point outside a circle are equal in length.

The given problem can be solved as follows,

The circumference of a circle is given as C = πd where d is the diameter of the circle.

Suppose, the circumference and diameters for both the circles are C₁, d₁ and C₂,d₂ respectively.

Now, the expression for circumference can be written as,

C₁ = πd₁

And, C₂ = πd₂

As per the question C₁ = 1/2C₂, then the following equations can be written as,

πd₁ = 1/2πd₂

⇒ d₁ = 1/2d₂

Hence, the diameters of the two circles are also in the same ratio.

A right rectangular prism has base dimensions of 3 inches by 12 inches and a height of 5 inches. An oblique rectangular prism has base dimensions of 4 inches by 9 inches and a height of 5 inches. Are the volumes the same?

Answers

Volume of right rectangular prism = Length x Width x Height 
Using the given dimensions, we can write:

Volume of right rectangular prism = 3 x 12 x 5 = 180 cubic inches

Volume of oblique rectangular prism = Base Area x Height
Base Area =  4 x 9 = 36 square inches

So, Volume of oblique rectangular prism = 36 x 5 = 180 cubic inches

Thus, we can conclude that the two volumes are the same.

A skier leaves an 8-foot-tall ramp with an initial vertical velocity of 28 feet per second. the function h = −16t^2 28t 8 represents the height h (in feet) of the skier after t seconds. the skier has a perfect landing. how many points does the skier earn? 1 point per foot in the air, 5 points per second in the air, and a perfect landing is 25 points.

Answers

The skier earns 35.875 points.

We can find the height in the air by using -b/2a:
-28/2(-16) = -28/-32 = 0.875

This will give the skier 0.875 points.

To find the amount of time in the air, we solve the related equation:
0=-16t²+28t+8

We will first factor out the GCF, -4:
0=-4(4t²-7t-2)

Now we will factor the trinomial in parentheses using grouping.  We want factors of 4(-2)=-8 that sum to -7; -8(1) = -8 and -8+1=-7.  This is how we will "split up" bx:
0=-4(4t²-8t+1t-2)

Now we will group the first two and last two terms:
0=-4[(4t²-8t)+(1t-2)]

We will factor out the GCF of each group:
0=-4[4t(t-2)+1(t-2)]

This gives us the factored form:
0=-4(4t+1)(t-2)

Using the zero product property, we know that either t-2=0 or 4t+1=0:
t-2=0
t-2+2=0+2
t=2

4t+1=0
4t+1-1=0-1
4t=-1
4t/4 = -1/4
t=-1/4

Negative time makes no sense, so t=2.  This gives the skier 5(2) = 10 points.

Counting the perfect landing, we have 25+10+0.875 = 35.875 points.
Final answer:

The skier earns approximately 27 points.

Explanation:

To find the total points earned by the skier, we need to calculate the time it takes for the skier to reach the ground. In this case, the height function h = -16t^2 + 28t + 8 represents the height of the skier after t seconds. To find the time it takes for the skier to reach the ground, we need to find the value of t when h = 0.

Setting h = 0, we get:

-16t^2 + 28t + 8 = 0

Using the quadratic formula, t = (-b ± sqrt(b^2 - 4ac)) / (2a), where a = -16, b = 28, and c = 8:

t = (-28 ± sqrt(28^2 - 4(-16)(8))) / (2(-16))

Simplifying the equation, we get:

t = (-28 ± sqrt(672)) / -32

t = (-28 ± 26) / -32

Since the skier has a perfect landing, we can disregard the negative value and take the positive value of t:

t = (-28 + 26) / -32

t = -2 / -32

t = 1/16

This means the skier takes 1/16 seconds to reach the ground. To calculate the total points earned, we need to find the total time the skier is in the air. Since the skier starts with an initial vertical velocity of 28 ft/s, we can use this velocity to find the time it takes to reach the ground:

t = h / v

t = 8 / 28

t = 2/7 seconds

Therefore, the skier is in the air for 2/7 seconds. To find the total points earned:

Points = (h * 1) + (t * 5) + 25

Points = (8 * 1) + ((2/7) * 5) + 25

Points = 8 + (10/7) + 25

Points = 189/7

So, the skier earns approximately 27 points.

aina, Kareem, and David have a total of $92 in their wallets. Kareem has $7 less than Raina. David has 3 times what Kareem has. How much do they have in their wallets?

Answers

Answer: Kareem has $17, David has $51, Raina has $24 

-----

Step 1:
Solve this by using a system of equations. Start by changing what you're given from words into equations. Put variables in for the peoples' names. Let's say Raina = R, Kareem = K, and David = D. You will have 3 equations:
1) Raina, Kareem, and David have a total of $92 in their wallets.
R + K + D (sum of all three) = 92 (total)

2) Kareem has $7 less than Raina
K = R - 7 (seven less than Raina)

3) David has 3 times what Kareem has.
D = 3K (three times Kareem)

-----

Step 2:
You can solve for the values of R, K, and D using substitution. Let's put the first equation, R + K + D = 92, all in terms of one variable, so we can solve for that variable. Since both equations 2 and 3 have K in relation to one of the other variables, I will be putting equation 1 in terms of K! Do this by substitution some equation of K in for variables R and D in the first equation.

From equation 2, we know that K = R - 7. Add 7 to both sides, making R = K + 7. 
From equation 3, we know that D = 3K. This is already in perfect form to substitute. 

Now substitute both R = K + 7 and D = 3K into the first equation. Simplify and solve for K:
R + K + D = 92
(K + 7) + K + (3K) = 92
5K + 7 = 92
5K = 85
K = 17

Kareem has $17 in his wallet.

-----

Step 3: 
Now that you know K = 17, plug that into equation 3, D = 3K, and solve for how much David has:
D = 3K
D = 3(17)
D = 51

David has $51 in his wallet.

-----

Step 4: 
Finally, plug K = 17 into equation 2, K = R - 7, to find how much Raina has: 
K = R - 7 
17 = R - 7
R = 24

Raina has $24 in her wallet.
Final answer:

Kareem has $17, Raina has $24 ($17 + $7) and David has $51 (3 x $17).

Explanation:

Let's represent the amount of money that Kareem has in his wallet as 'K'. Since Kareem has $7 less than Raina, we can represent Raina's amount of money as 'K + 7'. David has 3 times what Kareem has, so we can represent David's amount of money as '3K'.

According to the problem, the sum of all three amounts is $92. So we can set up the equation: K + (K + 7) + 3K = 92.

Combining like terms, we get 5K + 7 = 92. Subtracting 7 from both sides, we have 5K = 85. Dividing both sides by 5, we find that K = 17. Therefore, Kareem has $17, Raina has $24 ($17 + $7) and David has $51 (3 x $17).
