Answer:
{ 8, 2}
Step-by-step explanation:
Basic algebra, the object which is not in a set quantity, which we have to find, is the "some vans" and the "some buses"
So let the number of van be x
Let the number of buses be y
So, since there are 10 vehicles,
x+y=10
Makes sense right
Now, it says that every car can carry 6 students, and every van can carry 35 students, so in another way, we could represent this by saying
6 x Number of van + 35 x Number of buses
thus,
6x + 35y
And since 118 students went on the field trip, this means that
6x +35y = 118
So now we have two equations,
x + y = 10
6x + 35y = 118
We can solve this with substitution
x + y = 10
x = 10 - y
Thus, x = 10-y
Put this in this
6(10-y)+ 35y= 118
60-6y+35y=118
60+29y=118
29y=118-60
29y= 58
y = 58/29
y = 2
Thus, the number of buses, y, is 2
Now since there are 10 vehicles, and 2 are buses, then the other are 8 van

The cross-section of a wall is 7/16 of an inch thick. If the drywall is 1/4 inches thick, how thick is the texturing on wall? A. 3/16, b. 6/12, C 1/4, D 6/16
When the cross-section of a wall is 7/16 of an inch thick and the drywall is 1/4 inches thick, the thickness of the texturing on wall is A. 3/16
How to calculate the Fraction?A fraction simply means a piece of a whole. In this situation, the number is represented as a quotient such that the numerator and denominator are split. In this situation, in a simple fraction, the numerator as well as the denominator are both integers.
From the information, the cross-section of a wall is 7/16 of an inch thick. If the drywall is 1/4 inches thick. The thickness of the texturing on the wall is the total thickness of the wall minus the thickness of the drywall. The total thickness of the wall is 7/16 inches, and the thickness of the drywall is 1/4 inches, so the thickness of the texturing is:
= 7/16 inches - 1/4 inches
= 3/16 inches.
Therefore, the answer is A. 3/16 inches.

Oy> ²x + 3
Oy< ²x + 3
Help please
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.
How do you find the linear inequality of a graph?The boundary line that separates the coordinate plane into two halves by a linear inequality represents the solutions to the inequality in one half. For > and, the border line is solid, and for and, it is dashed.
To determine the equation governing the inequality line, enter your slope and a point into the formula y = mx + B, where "m" denotes the slope, "x, y" denotes a point on the line, and "b" is the y-intercept. By inserting (0, 0), you get 0 = 0 + b, which equals 0.
When you rewrite the equation, you get y = x/2. The linear inequality x - 5 > 3x - 10 is an illustration. Due to the greater than symbol being utilised in this inequality, the LHS is clearly greater than the RHS.

Answer:
No it does not suggest that a majority of students at the university do not share this belief
Step-by-step explanation:
No it does not suggest that a majority of students at the university do not share this belief
It is so because we do not know what is the population of university students and how much 178 people relate to the actual population of the university.

The volume of the parallelopiped is 14 cubic units
What is the volume of a parallelopiped?The volume of a parallelopiped with vector sides a, b and c is given by
V = (a × b).c
We know that the parallelopiped has sides
a = (2, 1, 0)b = (3, - 1, 2) and c = (4, 0, 3)Thus, we proceed as follows
(a × b) = (2, 1, 0) × (3, -1, 2) = (2 × 3)i × i + (2 × -1)i × j + (2 × 2)i × k + (1 × 3)j × i + (1 × -1)j × j + (1 × 2)j × k + (0 × 3)k × i + (0 × -1)k × j + (0 × 2)k × k
Since
i × i = 0, j × j = 0, k × k = 0, i × j = k, j × i = -k, j × k = i, k × j = -i, k × i = j, i × k = -j,So, we have
(a × b) = (2, 1, 0) × (3, -1, 2) = (6) × 0 + (-2)k + -(4)j + 3i + (-1) × 0 + (2)i + -(3)j + -(0)i + (0) × 0
= 0 -2k - 4j + 3i + 2i - 3j - 0 + 0
= 5i -7j - 2k
= (5, -7, -2)
Since (a × b) = (5, -7, -2)
Thus, the volume of the parallelopiped is
V = (a × b).c
= (5, -7, -2).(4, 0, 3)
= 5 × 4 + (-7 × 0) + (-2 × 3)
= 20 - 0 - 6
= 14
So, the volume is 14 cubic units

Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 7 times out of 10 attempts. Tasha has hit the ball 10 times out of 16 attempts. Which player has a ratio that means they have a better batting average?
Tasha, because she has the lowest ratio since 0.7 < 0.625
Tasha, because she has the highest ratio since 56 over 80 is greater than 50 over 80
