Nancy has x coins. Kevin has 2 coins fewer than two times the number of coins Nancy has. Write and simplify an expression for the total number of coins Nancy and Kevin have.

The 20-inch rod forms a right triangle with the 15 inches tall box

The value of x in the diagram is 13.2 inches

To calculate the value of x, we make use of the following Pythagoras theorem

[tex]20^2 = 15^2 + x^2[/tex]

Evaluate the exponents in the above equation

[tex]400 = 225 + x^2[/tex]

Subtract 225 from both sides of the equation

[tex]175 = x^2[/tex]

Take the square root of both sides

[tex]x = 13.2[/tex]

Hence, the value of x in the diagram is 13.2 inches

Answer:

x+2y+8=0

Step-by-step explanation:

The equation of straight line passing through the given points

(x 1,y1) = (6,-7)

(X2,y2)=(4,-6)

is given by following formula

y-y1={(y2-y1)/(x2-x1)}×(x-x1)

y+7={(-6+7)/(4-6)}×(x-6)

y+7={1/(-2)}×(x-6)

-2y-14=x-6

0=x+2y-6+14

x+2y+8=0

This is the required equation for line passing through (6,-7) and (4,-6)

Answer:

D.165

Step-by-step explanation:

m varies directly with n

m = 120 when n = 8

given this we want to find m when n = 11

we can use the direct variation equation to do so

y = kx but instead of x and y values we have values of m and n

m = kn

the constant is k, we need to solve for it, we can do so by plugging in m = 120 and n = 8

120 = k(8)

solving for k

divide both sides by 8

k = 15

the constant of variation is 15

now we want to find m when n = 11

using the direct variation equation we acquire

m = 11(15)

multiply 11 and 15

m = 165

the answer is D

Answer:

Factoring x2-15x-34

The first term is, x2 its coefficient is 1 .

The middle term is, -15x its coefficient is -15 .

The last term, "the constant", is -34

Step-1 : Multiply the coefficient of the first term by the constant 1 • -34 = -34

Step-2 : Find two factors of -34 whose sum equals the coefficient of the middle term, which is -15 .

-34 + 1 = -33

-17 + 2 = -15 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -17 and 2

x2 - 17x + 2x - 34

Step-4 : Add up the first 2 terms, pulling out like factors :

x • (x-17)

Add up the last 2 terms, pulling out common factors :

2 • (x-17)

Step-5 : Add up the four terms of step 4 :

(x+2) • (x-17)

Step-by-step explanation:

Since 6 will remain constant throughout the testing, we just need to find all prime numbers 1-6.

1 - is not prime nor composite

2 - is prime

3 - is prime

4 - 2x2=4, so composite

5 - is prime

6 - 2x3=6, so composite

Therefore, 2, 3, and 5 are prime numbers, and there are 3 of them.

Answer:

x = 24

Step-by-step explanation:

A triangle has a total of 180 degrees as its inner angle measurement.

If you look at the bigger triangle, it has two out of three angles: 94 and 41.

Since we know the angle has to be 180, we can simply subtract the sum of 94 and 41. We get 45 degrees.

Now that we have that measurement, we look at the smaller triangle. The 45 degrees is shared both by the bigger one and the smaller one. Which gives us two out of three angles for the smaller one.

Again, add 111 and 45 and then subtract the result from 180. We get 24 degrees.

Answer:

Step-by-step explanation:

The radius is approximately . 96 ft.

We will use the formula Circumference = 2pi(radius)

=> C=2pi(r)

=> Substitute 3.14 for pi, and 6 for C

=> 6 = 2(3.14)r

=> 6 = 6.28r

=>  .955 =r

=>  The radius is approximately .96 ft.

Answer:

a6 = 18,000

Step-by-step explanation:

a1 = 6

an = 5a(n-1)

a2 = 5a(2-1) = 5a1 = 5•6 = 30

a3 = 5a(3-1) =5a2 = 5•30 = 150

a4 = 5a(4-1) = 5a3 = 5•150 = 720

a5 = 5a(5-1) = 5a4 = 5•720 = 3600

a6 = 5a(6-1) = 5a5 = 5•3600 = 18000
