Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km left to bike. If Dina’s biking speed was 5 km/h, find Masha’s biking speed.
Answer:
4 km/hr
Step-by-step explanation:
Dina and Masha started out on a 10 km bike path at the same time.
Distance = 10 km
Dina’s biking speed was 5 km/h
Time taken by Dina is Distance / speed
So [tex]time (Dina) = \frac{10}{5} =2[/tex]
Time taken by Dina is 2 hours
Same time is taken by Masha but 2 km left
So distance covered by Masha in 2 hours is 10-2 = 8 km
We know speed = distance / time
[tex]speed of Masha = \frac{8}{2}=4[/tex]
Masha’s biking speed= 4km/hr

An architectural drawing of a building shows the elevation of the basement floor to be –12 feet. The elevation of the roof is 32 feet. What is the total distance from the roof to the basement floor?
The total distance from the roof to the basement floor in the architectural drawing is 44 feet, found by adding the basement's distance from ground level (12 feet) to the roof's elevation (32 feet).
Explanation:In the given scenario, we need to find the total distance from the basement to the roof. Given the elevation of the basement is -12 feet and the elevation of the roof is 32 feet, we simply need to add these two distances together. Since the basement is below ground level, its elevation is negative. Therefore, its distance from the ground level is 12 feet, not negative 12. We can treat this as an absolute value.
To calculate the total distance, we add the absolute value of -12 (which is 12) to 32, which gives us 44 feet. Thus, the total distance from the roof to the basement floor is 44 feet.

In triangle QRS, QR = 2x + 5, RS = 3x - 1, and SQ = 5x. Solve for x.
To solve for x in triangle QRS, set up an equation using the given information. However, there is no unique solution for x.
Explanation:To solve for x in triangle QRS, we need to set up an equation using the given information. Firstly, observe that the sum of the lengths of the three sides of a triangle is equal to the perimeter of the triangle. So, we have (2x + 5) + (3x - 1) + (5x) = perimeter of QRS. Simplifying this, we get 10x + 4 = perimeter of QRS. Next, we need to consider the fact that the perimeter of a triangle is equal to the sum of the lengths of its sides. So, we can set up the equation 10x + 4 = QR + RS + SQ. Substituting the given lengths, we have 10x + 4 = (2x + 5) + (3x - 1) + (5x). Solving this equation will give us the value of x.
10x + 4 = 2x + 5 + 3x - 1 + 5x
10x + 4 = 10x + 4
When we simplify this, we see that both sides of the equation are equal. Therefore, x can take on any value and there is no unique solution for x in this case.

The requried factor of the given quadratic expression [tex]3x^2 + 4x - 4[/tex] is (3x-2). Option C is correct.
To find the factor of the quadratic expression [tex]3x^2 + 4x - 4[/tex], we need to identify two binomials that, when multiplied together, result in the given expression.
The expression is in the form of [tex]ax^2 + bx + c[/tex], where a = 3, b = 4, and c = -4.
To factor the quadratic expression, we look for two binomials of the form (mx + p) and (nx + q) such that:
(mn) = a (which is 3 in our case), and
(pq) = c (which is -4 in our case).
Now, we need to find the factors of 3 and -4:
Factors of 3: 1, 3
Factors of -4: 1, -1, 2, -2, 4, -4
Now, we need to find combinations of these factors such that their product is 3 (the coefficient of [tex]x^2[/tex]) and -4 (the constant term). The combination that works is:
3 * -1 = -3
So, the two binomials are (3x - 2) and (x + 2) because:
[tex](3x - 2) * (x + 2) = 3x^2 - 2x + 6x - 4\\ \ \ \ \ \ \ \ \ \ \ = 3x^2 + 4x - 4[/tex]
Therefore, the correct factor is C.) (3x - 2).

x^3 + 3x^2 – 2x – 6 can be factored as (x+3)(x^2-2)
x^3 – 2x^2 + 3x – 6 can be factored as (x-2)(x^2+3)
4x^4 + 4x^3 – 2x – 2 can be factored as 2(x+1)(2x^3-1)
2x^4 + x^3 – x + 2 can't be factored.
Therefore, 2x^4 + x^3 – x + 2 is a prime polynomial.
In this exercise we have to use the knowledge of prime polynomials to find what cannot be factored, so we have;
A) Can be factored.
B) Can be factored.
C) Can be factored.
