Do modern scientists believe that protons and nuetrons are not made of smaller particles

anyanavicka [17]

Answer: Thus, protons and neutrons are no more indivisible than atoms are; indeed, they contain still smaller particles, which are called quarks. Quarks are as small as or smaller than physicists can measure.

In △ABC,a=34, b=18, and c=17. Find m∠A. A. 14.1 B. 132.6 C. 152.5 D. 101.5

igomit [66]

Answer:

C. m < A = 152.5 degrees.

Step-by-step explanation:

Use the Cosine Rule:

a^2 = b^2 + c^2 - 2.b.c.cos A

34^2 = 18^2 + 17^2 - 2.18.17 cos A

2.18.17 cos A = 18^2 + 17^2 - 34^2

cos A = (18^2 + 17^2 - 34^2) / (2.18.17)

cos A = -0.88725

m < A = 152.5 degrees.

One small airplane has 44 seats. The flight crew sits in two of these seats. The remaining seats are divided equally into 7 rows

Amiraneli [1.4K]

The number of seats in each row is an illustration of mathematical expressions.

The numerical expression for the number of seats in each row is: $\mathbf{\frac{44 - 2}{7}}$
The number of seats in each row would be 6

The given parameters are:

$\mathbf{Total\ Seats = 44}$

$\mathbf{Flight\ Crew = 2}$

$\mathbf{Rows = 7}$

So, the remaining seat is calculated as:

$\mathbf{Remaining = Total\ Seats - Flight\ Crew }$

Substitute known values

$\mathbf{Remaining = 44 - 2}$

The number of seat in each row is calculated as:

$\mathbf{Seats = \frac{Remaining}{Rows}}$

Substitute known values

$\mathbf{Seats = \frac{44 - 2}{7}}$

Hence, the numerical expression for the number of seats in each row is:

$\mathbf{\frac{44 - 2}{7}}$

When the expression is solved, the number of seats in each row would be 6

What is the equation of a line parallel to Y=-3x+5 that passes through point (6,8)?

babymother [125]

9514 1404 393

Answer:

y = -3x +26

Step-by-step explanation:

We assume the given line is ...

y = -3x +5

This is in slope-intercept form:

y = mx +b

where m = -3 and b = 5.

The parameter m represents the slope of the line. A parallel line will have the same slope, so will be of the form ...

y = -3x +b

We can find the value of b using the given point:

8 = -3(6) +b

26 = b . . . . . . add 18

So, the equation of the parallel line through (6, 8) is ...

y = -3x +26
