Answer:

36 neutrons

Step-by-step explanation:

The ratio of the protons to neutrons is 5:6, or 5 protons/6 neutrons. You know there are 30 protons, so this means you can set up proportions. Keeping the protons on the top, 5 protons/6 neutrons = 30 protons/x neutrons. You can cross-multiply from here, but how I find it helpful to think of it is seeing that you have to multiply 5 protons by 6 to get to 30 protons, so you'd have to also multiply the 6 neutrons by 6 to get x neutrons. Doing so (6x6) will get you 36. Don't forget your units! (:

Step-by-step explanation:

Men=5

Women=3

Available Strength:

Men=7

Women=6

Objective:Finding no of such committees where particular 2 women are never together.

So initially ,Total possible number of commitee=7c5×6c3=420.

Now we need to find total committes where two particular women say(Sita and Gita ) are never together.

Approach—->

As the commitee requires 5 men and 3 women.

Let us first find number of committees where Sita and Gita are always together.

Hence we reserve 2 women seats for them.

Now we need one women out of remaining 4 women.

So possible number of such commitees 7c5×4c1.

=84.

Hence number of committees where Sita and Gita are never together

=420–84

=336.

Answer:

y=88 x=42

Step-by-step explanation:

Since the total measurments of one triangle have to equal 180 and one angle is already 50, and the angle on the oppisite side of the y angle is 90 the only logical number for y would be 88. Hope this helped :)

Answer:

In Celsius the degree is 50°

Step-by-step explanation:

Put the 122° into the equation given.

Exponential functions can either represent growth or decay.

Part A:

The function is given as:

[tex]f(x) = 1264(1.09)^x[/tex]

The above function is an exponential function.

An exponential function is represented as:

[tex]f(x) = ab^x[/tex]

Where b represents the rate.

When b > 1, then the function is increasing

By comparison:

[tex]b = 1.09[/tex]

1.09 is greater than 1

Hence, the amount of money in account A is increasing.

Part B:

Divide any two concurrent values on the table, to determine the rate of the table.

So, we have:

[tex]b = \frac{1512.50}{1375}[/tex]

[tex]b = 1.10[/tex]

By comparison:

1.10 is greater than 1.09 (the rate of account A).

Hence, account B records a greater percentage change in the amount of money

A. because b > 1, the function is increasing, so the amount of money in account A is increasing.

B. 1.10 is greater than 1.09, so account B has more percentage change in the amount of money

Step-by-step explanation: 10 but thanks green guy

Answer:

x = 10

Step-by-step explanation:

The triangle has 2 congruent sides and is therefore isosceles, then the 2 base angles are congruent, both 67°

The sum of the 3 angles is 180° , that is

4x + 6 + 67 + 67 = 180

4x + 140 = 180 ( subtract 140 from both sides )

4x = 40 ( divide both sides by 4 )

x = 10

Answer:

x^2-10x+25

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2 so a=x and b=-5 so the expression is x^2-10x+25

Answer:

x^2-10x+25

Step-by-step explanation:

Distribute

(x-5)(x-5)

x(x-5)-5(x-5)

Distribute again

x(x-5)-5(x-5)

x^2-5x-5(x-5)

Distribute one last time

x^2-5x-5(x-5)

x^2-5x-5x+25

combine like terms

x^2-5x-5x+25

x^2-10x+25

Answer:

x < -8/21

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

Step 2: Add 3x to both sides.

Step 3: Subtract 10 from both sides.

Step 4: Multiply both sides by 2/21.

Therefore, the answer is x < -8/21.

Answer:

Remember that the slope of perpendicular lines are negative reciprocals of each other.

Step-by-step explanation:

y = 1 - 2x     the slope is -2     the value of the x term.

So the slope of the new line using point (- 1, 2)  is  1/2.

Now use y = mx + b where y = -1, x = 2, and m = 1/2 .

y = mx + b

-1 = 1/2(2) + b                solve for "b", the y-intersect

-1 =  1 + b

-2 = b

The line that is perpendicular to y = 1 - 2x  is  y = 1/2x - 2

Answer:

Step-by-step explanation:

5x-6=64

x=14

64-14=50

Step-by-step explanation:

let the first equation be l1 and the second equation be l2

then the product of L1.L2=1 the line is perpendicular and l1=l2 the line is parallel

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

The cost of one pizza is $10.95. The cost of 2 pizzas would be equivalent to the multiplication of $10.95 by 2. Since we are not provided with the information on the total amount of pizza she bought, the total number of pizza bought would be represented with p.

Thus the total cost of p boxes of pizza = $10.95 x p = $10.95p

The total amount spent on sodas is $12.57.

The total amount spent is $89.22.

The equation that models the situation is: 89.22 = $10.95p  +  $12.57.

[tex]3 \frac{1}{2} - 4 \frac{3}{4} = \frac{7}{2} - \frac{19}{4} = \frac{14}{4} - \frac{19}{4} = - \frac{5}{4} [/tex]

Answer:

x = 1 , y = 4

Step-by-step explanation:

I am assuming you're looking for what x and y are? If so, then we know that

DC and AB equal each other, so

4x + y = 8

CB and AD equal each other, so

2x + y = 6

We have two equations that cannot be solved on their own, so we must solve them as a system of equations. One process to solve is elimination.

4x + y = 8

2x + y = 6

we can multiply the second equation all by -1 to make the y's cancel out and give us x. so,

4x + y = 8

-1(2x + y) = 6

4x + y = 8

-2x -y = -6

now solve them vertically. we get:

2x = 2

and so x = 1.

Now that we found x, we must find y. Using any of the two equations froom above, we can substitue our x value of 1 into it to find y. I will use the first one.

4x + y = 8

4(1) + y = 8

4 + y = 8

y = 8 - 4

y = 4

so our x is 1 and y is 4.

hope this helps! (:
