Answer:
25 ft
Step-by-step explanation:
a² + b² = c²
7² + 24² = c²
49 + 576 = c²
c² = 625
c = √625
c= 25
Answer:
D. 25 ft.
Step-by-step explanation:
To find the missing length of any right triangle, you can use the Pythagorean Theorem (A^2+B^2=C^2) to solve. A and B represent the legs (which we do have) and C represents the hypotenuse (which we are trying to find). Insert our known values into the theorem, and we will get 24^2+7^2=C^2. Now we just do the basic math for the numbers that we have (24^2 is 576; 7^2 is 49), and that added up would equal to 625. Now, since C is being squared on the other side, we now have to root both sides. On the side where C is, the radical and the square will cancel out each other, leaving us with just C. But, on the side where 625 is, it should root to 25. Since C is by itself now, the number on the other side (25) will be our answer. Therefore, the missing side is 25 feet long.

Solve 2x2 + 8 = 0 by graphing the related function.
Answer:
The values of x are x= 2i and x= -2i
Step-by-step explanation:
We need to solve the equation:
2x^2 + 8 =0
Taking 2 common
2(x^2 +4) =0
Dividing both sides by 2
x^2+4 =0
Adding -4 on both sides
x^2 +4 -4 = 0-4
x^2 = -4
Taking square root on both sides we get
√x^2 = √-4
we know √4 = 2 and √-1 = i so answer is:
x = ± 2i
The values of x are x= 2i and x= -2i
The graph is shown in figure attached.
To solve 2x² + 8 = 0 by graphing, one plots the corresponding quadratic function f(x) = 2x² - 8, which is a parabola that opens upwards. The equation has no real solutions as the function does not cross the x-axis, indicating that the original quadratic equation has no real roots.
Explanation:To solve the quadratic equation 2x² + 8 = 0 by graphing the related function, we first need to rewrite the equation in the standard form of a quadratic function, which is f(x) = ax² + bx + c. In this case, the equation becomes f(x) = 2x² + 0x - 8.
The roots of the equation are the values of x where the function crosses the x-axis. To find these, we set the function equal to zero and solve for x. Subtracting 8 from both sides gives us 2x² = -8. Dividing by 2, we get x² = -4. Taking the square root of both sides, we see that x could be either positive or negative square root of -4, which does not have a real solution since you can't have a real number whose square is negative. Therefore, the graph of the function will not cross the x-axis and there are no real roots to this equation.
If we were to graph this function, we would plot the quadratic curve and notice that it is a parabola opening upwards because the coefficient of x² is positive. However, as we have established there are no real solutions, this would be confirmed by the fact that the vertex of the parabola is above the x-axis.
What is the difference between the rational expressions below? 3x+1/x^2-5/x
Answer:
(3x^2-5x-5)/(x^2+x) <--- answer
Step-by-step explanation:
3x/(x+1) - 5/x = (3x^2 - 5(x+1) )/[ x(x+1) ]
= (3x^2 - 5x - 5)/(x^2 + x)
The difference between the rational expressions 3x+1/x and 5/x is 3x - 4/x.
Explanation:The difference between these two rational expressions will be obtained by subtracting the second expression from the first. To do this, we first need to simplify the expressions wherever possible. The first expression, 3x + 1/x, remains as it is. The second expression, 5/x, is a simple fraction and can't be simplified any further either.
Subtracting the second from the first, you get (3x + 1/x) - (5/x) which simplifies to 3x - 4/x. The difference between these two rational expressions is hence 3x - 4/x.

Linda, Dale, and Jim sent a total of 83 text messages over their cell phones during the weekend. Jim sent 7 more messages than Linda. Dale sent 4 times as many messages as Jim. How many did they each send?
Answer: The answer is 94
Step-by-step explanation: First you should pay attention to the main numbers and since more and many are addition word than you should add 7 + 4 which equals 11 then add 83 + 11 which would equal 94. Tell me if the answer is wrong and I would find another way to answer it.
Final answer:
Linda sent 8 text messages, Jim sent 15 messages, and Dale sent 60 messages during the weekend.
Explanation:
The question asks to solve a word problem to find out how many text messages Linda, Dale, and Jim sent over the weekend.
Let's denote the number of messages Linda sent as L, Jim as J, and Dale as D.
The problem states that Jim sent 7 more messages than Linda, so J = L + 7.
Dale sent 4 times as many messages as Jim, so D = 4J.
Together they sent 83 messages, which gives us the equation L + J + D = 83.
Substituting the expressions for J and D in terms of L into the equation, we get L + (L + 7) + 4(L + 7) = 83.
This simplifies to 6L + 35 = 83. Solving for L gives us L = 8.
This means Linda sent 8 messages, Jim sent 15 messages (8 + 7), and Dale sent 60 messages (4 times 15).
The answer please
To the picture i just sent you
The correct answer is D, since if you simplify the equation 11 + 4 < -8 you get x < -2. Since -2 is greater than x, the arrow would need to point to the left signifying that it is a lesser value.

Find the length of a square with an area of 169 in2.
A. 338 in
B. 106 in
C. 26 in
D. 13 in
Find the length of a side of a square with an area of 169 in^2.
Answer:
D. 13 in
Step-by-step explanation:
A square has sides of equal length.
A = L^2 where: A = area and L = side
L^2 = 169
L=√169
L=13 in^2.
The length of a side of a square with an area of 169 in2 is calculated by taking the square root of the area, which is 13 inches. The correct answer is D. 13 in.
The student is asking to find the length of a side of a square given that the area of the square is 169 square inches. The formula to calculate the area of a square is side length squared, which can be written as:
Area = side × side
To find the side length, we need to take the square root of the area:
Side = √169
Upon calculation, the side length is:
Side = 13 {in}
Therefore, the correct answer is D. 13 in.

The width of a rectangle is 3 units less than the length. The area of the rectangle is 28 units. What is the width, in units, of the rectangle.
Answer:
4
Step-by-step explanation:
Let's call the width W and the length L.
We know the width is 3 less than the length, so:
W = L - 3
And we know the area is 28, so:
28 = WL
If we solve for L in the first equation:
L = W + 3
And substitute into the second equation:
28 = W (W + 3)
28 = W² + 3W
0 = W² + 3W - 28
0 = (W + 7) (W - 4)
W = -7, 4
Since W can't be negative, W = 4 units.
The width, in units, of the rectangle, if the area of the rectangle is 28 units, is 4 units.
What is area?The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.
Given:
The width of a rectangle is 3 units less than the length. The area of the rectangle is 28 units,
Write the equation as shown below,
b = l - 3 (Here, l is the length and b is the width)
l × b = 28
Solve the above equations,
l = 7 units and b = 7 - 3 = 4 units
Therefore, the width, in units, of the rectangle, if the area of the rectangle is 28 units, is 4 units.

Step-by-step explanation:
Leo needs 10 red roses and 15 pink daisies for every 5 bouquets he makes for a flower shop. Drag red roses and pink daisies into the box to show how many Leo needs for 3 bouquets.
Leo needs 6 red roses and 9 pink daisies for 3 bouquets, calculated by dividing the number of flowers needed for 5 bouquets by 5 and then multiplying by 3.
Explanation:To calculate the amount of red roses and pink daisies Leo needs for 3 bouquets, we first determine the number needed for one bouquet. Since Leo needs 10 red roses and 15 pink daisies for every 5 bouquets, we divide each amount by 5 to find the number per single bouquet:
Red roses per bouquet: 10 red roses / 5 bouquets = 2 red roses per bouquetPink daisies per bouquet: 15 pink daisies / 5 bouquets = 3 pink daisies per bouquetNow, we multiply the number of flowers needed per bouquet by 3 to find the total number for 3 bouquets:
Red roses for 3 bouquets: 2 roses per bouquet × 3 bouquets = 6 red rosesPink daisies for 3 bouquets: 3 daisies per bouquet × 3 bouquets = 9 pink daisiesTherefore, for 3 bouquets, Leo needs 6 red roses and 9 pink daisies.

Half a number increased by 10 is
equal to 35 less than twice the
number. What is the number?
x/2 + 10 = 35 - 2x
x/2 + 2x = 35 - 10
5x/2 = 25
5x = 25.2
5x = 50
x = 50/5
x = 10
The number is 10
Let's take it step by step to find the number for the given situation:
Step 1: Define the variable.
Let's denote the number we are trying to find as \( x \).
Step 2: Set up the equation based on the given information.
The problem statement says "Half a number increased by 10 is equal to 35 less than twice the number." This gives us the equation:
\[ \frac{1}{2}x + 10 = 2x - 35 \]
Step 3: Solve the equation.
Now we'll solve for \( x \). To do this, we need to get all terms involving \( x \) on one side and the constant terms on the other. Start by subtracting \( \frac{1}{2}x \) from both sides to get rid of the \( x \) term on the left-hand side:
\[ 10 = \frac{3}{2}x - 35 \]
Now, add 35 to both sides to isolate the \( x \)-related term on the right-hand side:
\[ 10 + 35 = \frac{3}{2}x \]
\[ 45 = \frac{3}{2}x \]
Next, to solve for \( x \), multiply both sides by \( \frac{2}{3} \) to cancel out the fraction:
\[ \frac{2}{3} \cdot 45 = x \]
\[ x = 30 \]
Step 4: Verify the solution.
Plugging the value of \( x \) back into the original equation to check:
\[ \frac{1}{2} \cdot 30 + 10 = 2 \cdot 30 - 35 \]
\[ 15 + 10 = 60 - 35 \]
\[ 25 = 25 \]
The equation is true, confirming that the solution \( x = 30 \) is correct.
Therefore, the number we were trying to find is 30.

true or false one milliliter of water has a mass of 2.00 grams
Answer:
false
Step-by-step explanation:
One milliliter of water has one gram of mass, and weighs one gram in typical situations
One milliliter of water does not have a mass of 2.00 grams.
Water has a density of 1g/mL, so one milliliter of water has a mass of 1 gram.
