Translate the following statement into an algebraic expression Use x for your variable. The sum of the cube of a number and seven times the number.​

Answers

Answer 1

Answer:

[tex]x^{3} + 7x[/tex]

Step-by-step explanation:

cube of a number is the number multiplied by itself thrice.

This means:

x × x × x = [tex]x^{3}[/tex]

Seven times (multiply, ×) the number(x) means:

7 × x = [tex]7x[/tex]

We are to sum (add, +) both:

[tex]x^{3}[/tex] + [tex]7x[/tex]

Answer is [tex]x^{3}[/tex] + [tex]7x[/tex]

Answer:

The area of the pentagon is: 354

Step-by-step explanation:

First draw two auxillery lines in the upper left hand corner to make a rectangle, and a right triangle.

Now that we have a rectangle we can find its area:

18·20=360

To find the lengths of the triangle sides:

20-16=4

18-15=3

Area of a right triangle formula: (leg a · leg b)/2

3·4=12 12/2=6

Now subtract the area of the triangle from the rectangle:

360-6=354

Customers at the palace pro shop receive a 10% discount if they are members. all customers must pay 7% in sales tax. The function f(x)=0.9x is used to determine the price of an item after the 10% member discount, where x is the regular price of the item. the function g(x)=1.07x is used to determine the total amount customers Pay for a purchase after all discounts are applied. Which function can be used to determine T(x), the total amount a member pays for an item with regular price of x dollars?

Answers

Answer: 0.963

Step-by-step explanation:

The function used to determine the total amount a member pays for an item with regular price of x dollars is T (x) = 0.963x.

What is discount?

A discount is a reduction made from a regular or list price.

This is subtracted from the regular price of an item.

Now it is given that,

The function used to determine the price of an item after the 10% member discount,

f(x) = 0.9x,

where x is the regular price of the item.

The function used to determine the total amount customers Pay for a purchase after sales tax is applied.

g(x) = 1.07x

Now, total amount to be paid by customer for an item with regular price of x dollars

T(x) = regular price* discount * sales tax

⇒T(x) = x*0.9* 1.07

⇒T(x) = 0.963x

Hence, The function used to determine the total amount a member pays for an item with regular price of x dollars is T (x) = 0.963x.

Gianna, Jada, and Brittney and a bunch of other friends had a horseshoe competition. Jada and Brittney were eliminated after two rounds because they were too busy texting but Gianna went onto round eight to win 47 pieces of gum. Later, she gave two to each of her friends. She only has 1 remaining. How many friends does she have?

Answers

Answer:

23 friends

Step-by-step explanation:

Let the number of friends she has = x

Total number of gum = 47 pieces

She gave 2 each to her friends, hence:

2x + 1 = 47

2x = 47 - 1

2x = 46

x = 46/2

x = 23

Therefore, the number of friends she has is 23

Paula knits hats. The number of hats h she can knit varies directly with the amount of yarn (y) in yards she has. The constant of proportionality is 42. Write an equation to represent the relationship between the number of yards of yarn Paula has and the number of hats she can knit.

Answers

Answer:

The equation showing the relationship between the number of yards of yarn Paula has and the number of hats she can knit is ;

h = 42y

Step-by-step explanation:

Here, we want to write an equation;

From the question, we are told that the number of hats h that can be knitted is directly proportional to the amount of yarn in yards

Since it is a proportional relationship;

h = k * y

where k is the constant of proportionality given as 42

Hence;

h = 42 * y

h = 42y

Part A

2 white, 5 red, 7 total

P(1st white) = 2/7

P(1st white, 2nd white) = P(1st white)*P(2nd white)

P(1st white, 2nd white) = (2/7)*(4/9)

P(1st white, 2nd white) = 8/63

Let m = 8/63

---------------

P(1st red) = 5/7

P(1st red, 2nd red) = P(1st red)*P(2nd red)

P(1st red, 2nd red) = (5/7)*(7/9)

P(1st red, 2nd red) = 5/9

Let n = 5/9 = 35/63

---------------

m+n = P(both are same color)

m+n = 8/63+35/63

m+n = 43/63

Answer: 43/63

========================================

Part B

m = P(first white then red)

m = (2/7)*(5/9)

m = 10/63

n = P(first red then white)

n = (5/7)*(2/9)

n = 10/63

r = P(second bead isn't same color as first)

r = m+n

r = 10/63+10/63

r = 20/63

Answer: 20/63

========================================

Part C

m = P(1st white, 2nd white)

m = (2/7)*(4/9)

m = 8/63

n = P(1st red, 2nd white)

m = (5/7)*(2/9)

m = 10/63

m+n = P(2nd is white)

m+n = 8/63+10/63

m+n = 18/63

m+n = 2/7

Answer: 2/7

========================================

Part D

If we withdraw 1 white bead, but we add it back in, then the probability of selecting white has not changed on the second selection.

The same can be said if we picked a red bead as well. This is because we simply replace the red bead with a copy of some other red bead.

Nick's statement is another way of saying replacement is happening.

like terms are things that are the same such as 1a and 2a, they share the same variable. so for question 1, the like terms would be B.

the second one is basically just adding them, so it’s kinda just -3+5. so your answer for number two is 2c.

the third one is very similar to the second one, it’s basically just 3-1+6. the answer to the third one is 8y.

the fourth one is also similar, you need to add like terms. so you need to look at the problem and add the a’s together since there are no other like terms found in the expression. so the simplified problem is -3a+3+8b.

same thing like 4 you need to look for like terms so the simplified expression is 2a+7rs

just distribute the 3 to all of them so like 3 times x and 3 times 2 so it’s 3x+6

same thing 6y-48

ok this one is a little different but mostly the same concept so 2a+4a+20-7 6a+13
