Julia wrote 14 letters to friends each month for y months in a row. Write an expression to show how many total letters she wrote.

Answers

Answer 1

Julia wrote 14 letters to friends each month for y months in a row means that Julia wrote 14 letters per month for y months, so the expression will be;
14y. In conclusion, 14y is an expression to show how many total letters she wrote. Have a nice day!

Answer 2

let y represent number of months in a row and
let S represents sum of letters that have been sent in y number of months

This simply means that we can write equation:
14*y = S

For any number of months we express it in equation above and we get total number of letters she wrote.

The baker pays $0.80 per pound for sugar and $1.25 per pound for butter. Write an expression that shows how much the baker will spend if he buys 6 pounds of butter and 20 pounds of sugar.

Answers

Answer:

$0.80x + $1.25y = z

Step-by-step explanation:

the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

The total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

What is Expression?

An expression is combination of variables, numbers and operators.

Given,

The baker pays $0.80 per pound for sugar

The baker pays $1.25 per pound for butter.

We need to write expression that shows how much the baker will spend if he buys 6 pounds of butter and 20 pounds of sugar.

Let x be the pounds for sugar

x be the pounds for butter

20x+6y=Total

As x=0.80 and y=1.25

20(0.80)+6(1.25)

16+7.5

23.5

Hence, the total money spent if the Baker bought 6 pounds of butter and 20 pounds of sugar would be $23.50.

This sequence represents the diameters of circles used to create an art project: 2.5 cm, 3.1 cm, 3.7 cm, 4.3 cm Let f(n) represent diameter in centimeters and n the term number in the sequence. Which equation represents the sequence of diameters?

Answers

ANSWER

The expression that represent the sequence of diameters is,
[tex]f(n) = 0.6n + 1.9[/tex]

EXPLANATION

The terms in the sequence are,

[tex]2.5,3.1,3.7,4.3[/tex]

The first term is
[tex]a = 2.5[/tex]

The common difference is

[tex]d = 3.1 - 2.5 = 0.6[/tex]

The formula for the nth term is given by,

[tex]f(n) = a + (n - 1)d[/tex]

We substitute the values in to the formula to get,

[tex]f(n) = 2.5+ (n - 1)0.6[/tex]

We expand the parenthesis to obtain,

[tex]f(n) = 2.5 + 0.6n - 0.6[/tex]

We rearrange to obtain,

[tex]f(n) = 0.6n + 2.5- 0.6[/tex]

We simplify to get,

[tex]f(n) = 0.6n + 1.9[/tex]

Answer:

[tex]f(n) = 1.9 +0.6n[/tex]

Step-by-step explanation:

The nth term of the arithmetic sequence is given by:

[tex]a_n = a_1+(n-1)d[/tex] ....[1]

where

[tex]a_1[/tex] is the first term

d is the common difference and n is the number of terms.

Here, f(n) represent diameter in centimeters and n the term number in the sequence.

Given the sequence represents the diameters of circles used to create an art project:

2.5 cm, 3.1 cm, 3.7 cm , 4.3 cm

This sequence is an arithmetic sequence with

[tex]a_1[/tex] = 2.5 and d = 0.6

Since,

3.1-2.5 = 0.6,

3.7-3.1 = 0.6

4.3-3.7 = 0.6

Substitute the given values in [1] we have;

[tex]f(n) =2.5+(n-1)(0.6)[/tex]

Using distributive property, [tex]a\cdot (b+c) = a \cdot b+ a\cdot c[/tex]we have;

[tex]f(n) = 2.5+0.6n-0.6[/tex]

Simplify:

[tex]f(n) = 1.9 +0.6n[/tex]

Therefore, the equation represents the sequence of diameters is, [tex]f(n) = 1.9 +0.6n[/tex]

What is the equation of the line that is parallel to y = -2x + 4 and goes through the point (1,7)

Answers

Answer: y = -2x+9

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

Work Shown:

The slope of the line y = -2x+4 is m = -2
Any line parallel to this line will also have a slope of m = -2
Parallel lines have equal slopes

Plug this slope, along with the given point (x1,y1) = (1,7) into the point slope formula. Then isolate y

y - y1 = m(x - x1)
y - 7 = -2(x - 1)
y - 7 = -2x + 2
y - 7 + 7 = -2x + 2 + 7
y = -2x + 9

A rectangular tabletop has a length of 4 3/4 feet and an area of 11 7/8 square feet. What is the width of the table top?

Answers

Well to find this first you will divide the area by the length.
If you can use a calculator just put 11.875/4.75 which gives you as your width 2.5.
If you can't then change them into irregular fractions so...
11 7/8 --> 95/8
4 3/4 --> 19/4
Then divide them
95/8 / 19/4
95/8 * 4/19
380/152= 2.5 or 2 1/2

I draw a card 50 times from a standard 52 deck and gets a heart 8 times what's the probability that I draw a heart on the next draw

Answers

To solve this problem, let us first define what probability is. By standard definition, probability is the ratio of how many times a selected event occurred over the total number of events which occurred. Hence:

Probability = number of times a selected event occurred / total number of events

In this case, our selected event is the drawing of a heart which occurred 8 times. While our total event is the total number of drawing of cards which occurred 50 times. Hence, the probability is:

Probability = 8 / 50

Probability = 4 / 25 = 0.16 = 16%

Therefore there is a 4/25 or 0.16 or 16% chance that the next draw will be a heart.

True or False? The point-slope form of a line is y + y1 = m(x + x1), where m is the slope and (x1, y1) is a point on the line. It's false right?

Answers

False.

Point-slope form is: y-y1=m(x-x1)

They used sums instead of differences...

Answer:

False

The correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .

Step-by-step explanation:

The formula for the point slope form passing through the point (a,b) is given by.

[tex](y-b)=m (x-a)[/tex]

Where m is the slope .

As given in the question.

m is the slope and (x1, y1) is a point on the line.

Thus the point slope form becomes

[tex](y-y1)=m (x-x1)[/tex]

Therefore the correct point slope form passing through points (x1,y1) is [tex](y-y1)=m (x-x1)[/tex] .

Consider the following sets. U = {ordered pairs on a coordinate plane} A = {ordered pair solutions to y = x} B = {ordered pair solutions to y = 2x} Which ordered pair satisfies A ∩ B?

Answers

Answer:

(0,0)

Step-by-step explanation:

We have,

U = { (x,y) : x,y belong to real numbers }

A = { (x,y) : (x,y) is a solution of y=x }

B = { (x,y) : (x,y) is a solution of y=2x }

We need to find the ordered pair (x,y) that belong to A[tex]\bigcap[/tex]B.

Let, (x,y) belong to A[tex]\bigcap[/tex]B

i.e. (x,y) belong to A and (x,y) belong to B

i.e. y = x and y = 2x

i.e. x = 2x

i.e. x = 0

Now, substitute x= 0 in any of the equation say y = x, we get y = 0.

Hence, the ordered pair satisfying A[tex]\bigcap[/tex]B is (0,0).

For a set U, The ordered pair satisfies A ∩ B is mathematically given as

x = 0, y = 0 (0,0)

Which ordered pair satisfies A ∩ B?

Question Parameter(s):

U = {ordered pairs on a coordinate plane}

A = {ordered pair solutions to y = x}

B = {ordered pair solutions to y = 2x}

if (x,y) belongs to AnB

y = x and y = 2x

x = 0

In conclusion, subsituting we have

y = x and y = 2x

y = 0
