how do you solve 0.7n-1.5+7.3n=14.5​

Answers

Answer 1

Answer:

n = 2

Step-by-step explanation:

Answer 2

Answer:

n = 2

Step-by-step explanation:

0.7n-1.5+7.3n=14.5​

Add like terms

(0.7n + 7.3n) + (-1.5) = 14.5

8n -1 .5 = 14.5

Add 1.5 to both sides.

8n =1 6

Divide both sides by 8.

n = 2

Select the correct choice below and, if necessary, fill in the answer box to complete your choice.​

Answers

Answer:

the solution to the equation is 8.  Any value apart from 8 is not a solution

Step-by-step explanation:

Given the equation

6/3x+2 - 1/x-4 = 0

6/3x+2 = 1/x-4

Cross multiply

6(x-4) = 3x+2

6x - 24 = 3x+2

6x-3x = 2 + 24

3x = 24

x = 24/3

x = 8

Hence the solution to the equation is 8.  Any value apart from 8 is not a solution

Kayla is thinking of a 3-digit number. * It is divisible by 18. * It is a palindrome (It reads the same left-to-right as it does right-to-left, like 252 and 848). * It is one less than a multiple of 5. What is Kayla’s number?

Answers

Answer:

414

Step-by-step explanation:

Let the number be aba as it is a palindrome

It divisible by 18, so it is an even number with sum of digits divisible to 9

2a + b = 9k

It is one less than a multiple of 5:

aba = 100a + 10b + a = 101a + 10b

Multiple of 5 will end with 0 or 5, it has to be 5 as a is even, then:

a = 5 - 1 = 4

The number 4b4 is divisible by 9 only if b = 1:

2*4 + b = 9k ⇒ b = 1

So the number is:

414

Lets verify:

414/18 = 23414 + 1 = 415- divisible by 5414 - is palindrome

at what value of x, the function 2x^3/3+2x^2-6x+4 is minimum​

Answers

Answer:

x=1

Step-by-step explanation:

We are given that

[tex]\frac{2x^3}{3}+2x^2-6x+4[/tex]

We have to find the value of x for which function is minimum.

Differentiate w.r.t x

[tex]f'(x)=2x^2+4x-6[/tex]

Substitute f'(x)=0

[tex]2x^2+4x-6=0[/tex]

[tex]x^2+2x-3=0[/tex]

[tex]x^2+3x-x-3=0[/tex]

[tex]x(x+3)-1(x+3)=0[/tex]

[tex](x-1)(x+3)=0[/tex]

[tex]x=1,-3[/tex]

Again, differentiate w.r.t x

[tex]f''(x)=4x+4[/tex]

[tex]f''(1)=4(1)+4=8>0[/tex]

[tex]f''(-3)=4(-3)+4=-8<0[/tex]

Hence, the function is minimum at x=1

One angle of a triangle is three times larger as another. the measure of the third angle is 50 degrees more than that of the smallest angle. Find the measure of each angle.

Answers

Answer:

Smallest angle of triangle=26 degrees

Second angle of triangle =78 degrees

Third angle of triangle =76 degrees

Step-by-step explanation:

Let x be the smallest angle of triangle

Second angle of triangle=3x

Third angle of triangle=x+50

We know that

Sum of angles of triangle=180 degrees

Using the property

[tex]x+3x+x+50=180[/tex]

[tex]5x=180-50[/tex]

[tex]5x=130[/tex]

[tex]x=\frac{130}{5}[/tex]

[tex]x=26[/tex] degree

Smallest angle of triangle=26 degrees

Second angle of triangle =3(26)=78 degrees

Third angle of triangle =26+50=76 degrees

Answer:

[tex]x=120[/tex]

Step-by-step explanation:

When two lines are parallel and intersected by a transversal, the alternate corresponding angles are supplementary (their sums equal 180). In the picture, the two parallel lines are intersected by the vertical lines. Then, one of the angles formed intersected again. This means that the sum of the two smaller angles, plus the alternate exterior angle is equal to 180. Hence the following equation can be formed;

[tex]x+20+40=180[/tex]

Simplify,

[tex]x+60=180[/tex]

Inverse operations;

If an order is valued at over $1000, then there is a probability of 0.63 that the customer will pay with a credit card. a. What is the probability that the next three independent orders will each be valued at over $1000

Answers

Answer:

0.074088

Step-by-step explanation:

Let

A:Value of order over $1000

B:Customer pay with credit card

We are given that

Probability of value of order over $1000,P(A)=0.42

If an order is valued at over $1000, then the probability that the customer will pay with a credit card, P(B/A)=0.63

We have to find  the probability that the next three independent orders will each be valued at over $1000

We know that

When two two events A and B are independent then

[tex]P(A\cap B)=P(A)\cdot P(B)[/tex]

Using the formula

The probability that the next three independent orders will each be valued at over $1000=[tex]0.42\times 0.42\times 0.42[/tex]

The probability that the next three independent orders will each be valued at over $1000=0.074088

Nicole can buy 3 pounds of Luce suppose an orchard for $4.95 or she can buy a 25 ounce bag of apples from the store for $3.79 which is the better deal?

Answers

9514 1404 393

Answer:

  orchard apples are lower-cost

Step-by-step explanation:

3 pounds is 48 ounces, so the equivalent to the store offering might be about 24 ounces for $4.95/2 ≈ $2.48.

This is substantially less cost per ounce than 25 ounces for $3.79. (24 and 25 are very near, but $2.48 and $3.79 are not.)

Orchard apples are the better deal.

write the first six terms of the geometric sequence with the first term 6 and common ratio 1/3

Answers

Answer:

6, 2, 2/3, 2/9, 2/27, 2/81

Step-by-step explanation:

The nth term of a geometric progression is expressed as;

Tn  = ar^n-1

a is the first term

n is the number of terms

r is the common ratio

Given

a = 6

r = 1/3

when n = 1

T1 = 6(1/3)^1-1

T1 = 6(1/3)^0

T1 = 6

when n = 2

T2= 6(1/3)^2-1

T2= 6(1/3)^1

T2 = 2

when n = 3

T3 = 6(1/3)^3-1

T3= 6(1/3)^2

T3= 6 * 1/9

T3 = 2/3

when n = 4

T4 = 6(1/3)^4-1

T4= 6(1/3)^3

T4= 6 * 1/27

T4 = 2/9

when n = 5

T5 = 6(1/3)^5-1

T5= 6(1/3)^4

T5= 6 * 1/81

T5 = 2/27

when n = 6

T6 = 6(1/3)^6-1

T6= 6(1/3)^5

T6= 6 * 1/243

T6 = 2/81

Hence the first six terms are 6, 2, 2/3, 2/9, 2/27, 2/81
