Answer:

Average velocity = 6.25 km/h

Step-by-step explanation:

Given : A horse began running due east and covered 25 km in 4.0 hr.

To find : What is the average velocity of the horse.

Solution : We have given

Displacement = 25 km

Time = 4 hr.

Velocity = $\frac{Total\ displacement}{time}$ .

Velocity = $\frac{25}{4}$ .

Average velocity = 6.25 km/h

Therefore, Average velocity = 6.25 km/h

A university offers 3 calculus classes: Math 2A, 2B, and 2C. A set of students have each taken at least one of the three classes

lyudmila [28]

Answer:

157

Step-by-step explanation:

We are given that

Number of students in maths 2A=n(2A)=51

Number of students in math 2B=n(2B)=80

Number of students in math 2C=n(2C)=70

Number of students in maths 2A and 2B= $n(A\cap B)=15$

Number of students in maths 2B and 2C= $n(B\cap C)=13$

Number of students in maths 2A and 2C= $n(A\cap C)=20$

Number of students in maths 2A ,2B and 2C=4

We have to find the number of students in a set.

Formula: $n(A\cup B\cup C)=n(A)+n(B)+n(C)-n(A\cap B)-n(B\cap C)-n(A\cap C)+n(A\cap B\cap C)$

Substitute the values in the given formula

$n(2A\cup 2B\cup 2C)=51+80+70-15-13-20+4=157$

Hence, total number of students in a set=157

Select the correct product.

AURORKA [14]

Answer:

Option A. $2x^{3}+7x^{2}+12x-8$

Step-by-step explanation:

we have

$(x^{2}+4x+8)(2x-1)$

Applying the distributive property

$(x^{2}+4x+8)(2x-1) =x^{2}(2x)-x^{2} +4x(2x)-4x+8(2x)-8\\ \\=2x^{3}-x^{2} +8x^{2}-4x+16x-8\\ \\= 2x^{3}+7x^{2}+12x-8$

Rocky thinks of an odd integer adds the next two consecutive integer which of these could be the sum

tekilochka [14]

Answer:

Step-by-step explanation:

1. Let x be the odd integer. Let y be the sum.

x + (x + 1) + (x + 2) = y

3x + 3 = y

Adding two consecutive integers to an odd integer will result in an even integer.

So, you can eliminate choices B and D since they are odd.

Lastly, plug in choices A and C for y and choose the answer that makes x an integer.

Choice C would give you the correct result.

3x + 3 = 44562

3x = 44559

x = 14853
