Mrs.lealas living room has an area of 144 square feet.
Her dining room is ⅓ the area of the living room and ⅖ the area of the kitchen. What is the area, in square feet, of the kitchen?
Answers
The Area of Kitchen is 120 square feet.
We have,
Area of living room = 144 square feet
So, the dining room
= 1/3 (area of living room)
= 1/3 (144)
= 48 square feet
and, Area of Dining room = 2/5 x Area of kitchen
48 = 2/5 x Area of kitchen
Area of kitchen = 48 x 5/2
Area of Kitchen = 24 x 5

A biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road. How much more does he need to travel? (distance)
Answers
The biker needs to travel 45 km more to complete his journey.
Given that, a biker traveled 2/5 of the road on the first day, then traveled 5 kilometers less on the next day, which is equal to 3/8 of the road, we need to find how much he need to cover more,
Let the total distance of the road be x,
So,
2x/5 - 5 = 3x/8
2x/5 - 3x/8 = 5
Solving for x,
Multiply by 40 to both sides,
16x-15x = 200
x = 200
Therefore, the total distance of the road is 200 km.
Since, he travelled =
200 (2/5) = 80 km + 200 (3/8) = 75 km = 155 km
Therefore, he needs to travel 200-155 = 45 km more.
Hence, the biker needs to travel 45 km more to complete his journey.

The equation will have the solution in the form of an imaginary number "i" as: x = (3 ± 2i)/2
What is an imaginary number in a quadratic equationIn a quadratic equation, an imaginary number is a complex number that can arise when trying to take the square root of a negative number.
We shall solve for x in the equation as follows:
(2x + 3)² - 2 = -6
add 2 to both sides
(2x + 3)² = 2 - 6
(2x + 3)² = -4
2x + 3 = √(-4) {taking square root of both sides}
subtract 3 from both sides
2x = 3 ± √(-4)
divide through by 2
x = [3 ± √(-4)]/2
note that: √(-4) = √(1-) × √4 where √(-1) = I, so;
x = (3 ± 2i)/2.

We have,
The formula given is incorrect.
The correct formula for Pythagorean triples with a given integer z is:
(z² - 1², 2z, z² + 1²)
Using this formula, we can find the two legs of the right triangle with hypotenuse 29 as follows:
z² + 1² = 29²
z² + 1 = 29²
z² = 29² - 1
z² = 840
z = √840
z = 28.98
Since z must be an integer, we can try integer values close to 28.98 to find one that works.
Trying z = 29,
a = z² - 1² = 840 - 1 = 839
b = 2z = 58

The required rate of simple interest is 1.75%.
Here, we have,
(Principal + Interest) is a straightforward interest equation.
A = P(1 + rt)
Where: A is the sum of the accrued principal and interest.
Principal Amount is P.
I is the interest rate.
r is the annual percentage rate of interest, or R/100.
R is the annual percentage rate of interest; R = r * 100 t is the length of time involved in months or years.
Since I = Prt,
the initial formula A = P(1 + rt) evolved from A = P + I to A = P + Prt,
which may be represented as A = P(1 + rt).
Given: Principal is $1,300
Rate is 7% and the amount earned that is A-P is $159.25.

Answers
Step-by-step explanation:
Arithmetic sequence with d = 2 a1 = -6
a20 = -6 + 2(20-1) = 32
To find the 20th term, we can use the formula:
an = a1 + (n - 1)d
where
an is the nth term of the sequence
a1 is the first term of the sequence
d is the common difference between the terms
n is the term we want to find
We are given that a1 = -6, d = 2, and n = 20. Substituting these values into the formula, we get:
a20 = -6 + (20 - 1)2
a20 = -6 + 38
a20 = 32
Therefore, the 20th term of the sequence is 32.

Answers
First, we can find the translation vector that moves point A to point A':
translation vector = A' - A = (3, -1) - (1, 3) = (2, -4)
Next, we can find the vector that connects point B to point A in the original triangle ABC:
vector AB = B - A
Then, we can rotate this vector using the rotation matrix for the desired angle of rotation:
90° clockwise rotation:
|0 -1| |x| |y'|
|1 0| * |y| = | -x'|
180° clockwise rotation:
|-1 0| |x| |x'|
| 0 -1| * |y| = |y'|
180° counterclockwise rotation:
|-1 0| |x| |-x'|
| 0 -1| * |y| = |-y'|
90° counterclockwise rotation:
| 0 1| |x| |-y'|
|-1 0| * |y| = | x'|
Finally, we can add the translation vector to the rotated vector to get the coordinates of the corresponding point in the new polygon A' B' C':
90° clockwise rotation: B' = A' + (AB rotated 90° clockwise + translation)
180° clockwise rotation: B' = A' + (AB rotated 180° clockwise + translation)
180° counterclockwise rotation: B' = A' + (AB rotated 180° counterclockwise + translation)
90° counterclockwise rotation: B' = A' + (AB rotated 90° counterclockwise + translation)
Using this method, we can find the coordinates of points B' and C' in the new polygon A' B' C'. Then, we can use the coordinates of these points to determine the direction and angle of rotation needed to move the original triangle to the new polygon.
The displacement of a train starting from a stop is given by the equation s(t) = 8\sqrt{t}+1 meters. Estimate the instantaneous velocity of the train at t = 9 seconds by considering the average velocities over the intervals [8.5, 9], [8.7, 9], [8.9, 9], [8.99, 9], [9, 9.01], [9, 9.1], [9, 9.3], and [9, 9.5].
Answers
The instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s
To estimate the instantaneous velocity of the train at t = 9 seconds, we can consider the average velocities over several small intervals of time that include the point t = 9. This is an approximation of the slope of the tangent line to the curve s(t) at t = 9, which is the instantaneous velocity.
We can calculate the average velocity over each interval by dividing the change in displacement by the change in time:
Average velocity from [8.5, 9] = (s(9) - s(8.5)) / (9 - 8.5) = (8√9 + 1 - 8√8.5 + 1) / 0.5 = 6.34 m/s (approx.)
Similarly, we can calculate the average velocities over the other intervals:
[8.7, 9]: 6.48 m/s (approx.)
[8.9, 9]: 6.60 m/s (approx.)
[8.99, 9]: 6.66 m/s (approx.)
[9, 9.01]: 6.67 m/s (approx.)
[9, 9.1]: 6.74 m/s (approx.)
[9, 9.3]: 6.87 m/s (approx.)
[9, 9.5]: 7.00 m/s (approx.)
As we consider smaller intervals closer to t = 9, the average velocities approach a limit, which is the instantaneous velocity at t = 9. In this case, we see that the average velocities are increasing as we approach t = 9, indicating that the instantaneous velocity at t = 9 is also increasing.
Based on these calculations, we can estimate that the instantaneous velocity of the train at t = 9 seconds is approximately 6.8 m/s (averaging the average velocities from [8.99, 9] to [9, 9.5]).

The simplification of the given expression is equal to 192524.3.
The expression is equal to,
√2 × √6 × √110 × √120 × √450 × √520
Simplify this expression by first simplifying the square roots under the radical signs,
√2 = √(2 × 1)
= √2 × √1
√6 = √(2 × 3)
= √2 × √3
√110 = √(2 × 5 × 11)
= √2 × √5 × √11
√120 = √(2 × 2 × 2 × 3 × 5)
= 2√2 × √3 × √5
√450 = √(2 × 3² × 5²)
= √2 × (3 × 5)²
= 15√2
√520 = √(2³ × 5 × 13)
= 2√2 ×√5 × √13
Substituting these simplifications back into the original expression, we have,
√2 × √6 × √110 × √120 × √450 × √520
= √2 × √2 × √3 × √2 × √5 × √11 × 2√2 × √3 × √5 × 15√2 × 2√2 ×√5 × √13

How many liters each of a 50% acid solution and a 60% acid solution must be used to produce 60 liters of a 55% acid solution? (Round to two decimal places if necessary.)
Answers
To produce 60 liters of a 55% acid solution, we need 18 liters of a 50% acid solution and 42 liters of a 60% acid solution.
Let x be the number of liters of the 50% acid solution needed, and y be the number of liters of the 60% acid solution needed.
We can set up two equations based on the amount of acid and the total volume:
0.50x + 0.60y = 0.55(60)
x + y = 60
Simplifying the first equation:
0.50x + 0.60y = 33
5x + 6y = 330 (multiplying both sides by 10)
We can solve for one variable in terms of the other in the second equation, and substitute into the first equation:
y = 60 - x
5x + 6(60 - x) = 330
Simplifying:
x = 18

Answers
The solution of the equation x - √x + 4 - 2√(x+3) =0 is given by x ≈ 0.449 or x = 2.
The expression is equal to,
x - √x + 4 - 2√(x+3) =0
By rearranging the terms and simplifying the expression as follows,
x - √x + 4 - 2√(x+3) = 0
⇒x + 4 = √x + 2√(x+3)
Square both sides to eliminate the square root,
⇒ (x + 4)² = (√x + 2√(x+3))²
⇒ x² + 8x + 16 = x + 4(x+3) + 4√x√x+3
⇒x² + 8x + 16 -x -4x -12 = 4√x√x+3
⇒ x² + 3x + 4 = 4√x√x+3
⇒x² + 3x + 4 = 4√x√(x+3)
⇒ x² + 3x + 4 = 4√(x²+3x)
Squaring both sides again gives,
⇒ (x² + 3x + 4)² = 16(x²+3x)
Expanding the left side gives,
x⁴ + 6x³ + 17x² + 24x + 16 = 16x² + 48x
Simplifying and rearranging the terms,
x⁴ + 6x³ + x² - 24x + 16 = 0
Factor this equation as follows,
(x² + 4x - 2)(x² + 2x - 8) = 0
The solutions are,
x²+ 4x - 2 = 0 or x² + 2x - 8 = 0
Solve each quadratic equation using the quadratic formula,
For x² + 4x - 2 = 0
x = (-4 ± √(4² - 4(1)(-2))) / (2(1))
⇒ x = (-4 ± √24) / 2
Simplifying the expression under the square root gives,
⇒ x = (-4 ± 2√6) / 2
⇒ x = -2 ± √6
For x² + 2x - 8 = 0
x = (-2 ± √(2² - 4(1)(-8))) / (2(1))
⇒x = (-2 ± √36) / 2
Simplifying the expression under the square root gives,
⇒ x = (-2 ± 6) / 2
⇒ x = -4 or x = 2

The trio of sides that will make a right triangle are the ones in the first option:
5, 12, and 13.
Which set would make a right triangle?Remember that for any right triangle, the sum of the squares of the two shorter sides must be equal to the square of the longest side.
So for example, for the first option we would have:
5^2 + 12^2 = 13^2
25 + 144 = 169
169 = 169
The equation is true, thus, these sides make a right triangle.

The volume of the triangular base prims is 21.6 inches cube.
How to find the volume of a triangular base prism?A triangular base prism is a prism with a triangular base. Therefore, let's find the volume of the triangular prism.
volume of a triangular prism = base area × height
Therefore,
base area = 1 / 2 bh
where
b = baseh = heightTherefore, the triangular base has angles 45, 45 and 90 degrees. Using trigonometric ratios let's find the other legs.
tan 45 = opposite / adjacent
tan 45 = x / 6
x = 6 inches
Therefore,
base area = 1 / 2 × 6 × 6
base area = 36 /2
base area = 18 inches²
Hence,
volume of the triangular base prism = 18 × 1.2
volume of the triangular base prism = 21.6 inches³

The measure of angle 1 is 107° suing the concepts of corresponding angles and linear pair of angles..
Given a line t which is a transversal line that cuts the two parallel lines m and n.
Here the angle which is linear pair to angle 1 and the angle 73° are corresponding angles.
By the corresponding angle theorem, the corresponding angles formed by two parallel lines cut by a transversal are equal.
So,
Measure of angle which is linear pair to 1 = 73°
Now linear pair of angles are supplementary.
∠1 + 73° = 180°
∠1 = 180° - 73°
∠1 = 107°
Hence the measure of angle 1 is 107°.
