Sally is making masks for her family. Her pattern calls for a rectangle that is 9 x 14. If one yard of fabric is 36 x 42 (after the salvage edge is removed), how many masks can she make from one yard of fabric? If her fabric was on sale for $3.00 per yard, what is the fabric cost of one mask? If her fabric is regularly priced at $9.00 per yard, what is the fabric cost of one mask? Answer: Number of masks: Cost using discount fabric: $ Cost using regular priced fabric:

Answer 1

Answer:

Answer:

how many masks can she make from one yard of fabric?

the maximum she can obtain is 4 (9 x 4 = 36) x 3 (14 x 3 = 42) = 12 masks from one yard of fabric.

If her fabric was on sale for $3.00 per yard, what is the fabric cost of one mask?

the fabric cost of 1 mask at a discount price = $3 / 12 = $0.25 per mask

If her fabric is regularly priced at $9.00 per yard, what is the fabric cost of one mask?

the fabric cost of 1 mask at regular price = $9 / 12 = $0.75 per mask

Well, for the third time in a row Kimberly (Haha jk), let's look at it by decimals. 0=0.00.....1/2=0.50.....1=1.00

0.00009999 would be closeset to 0 because it is the furthest away from the decimal point. The further you move away from the decimal point, the closer you get to zero.

What is the equation of -1/2 that passes through the point (6,-6) Options are ..1) y= 1/2x-3
2) y= -1/2x+3
3) y= -1/2x-3
4) y= -2x-3

Please explain why the answer is what it is.

Answers

formula of the line is
y = mx + c
we know y, m and x, find c

-6 = $- (1)/(2)$ (6) + c
-6 = -3 + c
-6 + 3 = -3 + 3 + c
-3 = c

y = $- (1)/(2) x$ - 3

Answer is the third one.

Solve for x. Leave your answer in simplest radical form.

There are two Right angled triangles in the given figure, with two missing sides, let's name the other missing side be "y "

According to Pythagoras theorem,

$\boxed{ \large \boxed{h {}^(2) = {b}^(2) + p{}^(2) }}$

note :

p = perpendicular / opposite side
b = base / adjacent side
h = hypotenuse

let's solve for " y² " first ( square of other missing side )

$➢ \: \: {y}^(2) = {8}^(2) + 3 {}^(2)$

$➢ \: \: {y}^(2) = 64 + 9$

$➢ \: \: {y}^(2) = 73$

now let's solve for "x " , by using pythagorous theorem

$➢ \: \: {x}^(2) = {y}^(2) + {6}^(2)$

$➢ \: \: {x}^(2) = 73 + 36$

$➢ \: \:x {}^(2) = 109$

$➢ \: \: x = √(109)$

Approximate :

$➢ \: \: 10.44 \: \: units$

A code is formed using four of these letters: A, B, I, K, N, O, and T. (Note that the order of the letters in the code matters; for example, ABIK is a different code from BAIK.)The size of the sample space is . The probability that the first three letters of the four-letter code are vowels is?

Answers

Answer: The size of the sample is 840.

The probability that the first three letters of the four-letter code are vowels is $=(1)/(35)$

Step-by-step explanation:

Th total number of letters given to form code of 4 letters = 7

Since, the order of the letters in the code matters, which means there is no repetition.

The total number of ways to form the code size = $7*6*5*4=840$

Therefore, The size of the sample is 840.

Since, there are 3 vowels and rest of 4 letters are consonant.

The number of ways to form code such that the first three letters of the four-letter code are vowels = $3*2*1*4=24$

The probability that the first three letters of the four-letter code are vowels is

= $(24)/(840)=(1)/(35)$

The probability that the first three letters of the four-letter code are vowels is 1/35 and the size of the sample is 840.

What is the explanation for the above?

Step 1 - Determine the sample size.

It is to be noted that the total number of letters given to form code of 4 letters = 7

Given that the order of the letters in the code matters, which means there is no repetition; hence,

The total number of ways to form the code size = 7 x 6 x 5 x 4 = 840

Thus, the size of the sample is 840.

Step 2 - Solve for the Probability

Given that there are 3 vowels and rest of 4 letters are consonant.

The number of ways to form code such that the first three letters of the four-letter code are vowels

= 3 x 2 x 1 x 4

= 24

Hence, the probability that the first three letters of the four-letter code are vowels is

= 24/840

= 1/35

A set of equations is given below:Equation C: y = 2x + 6

Equation D: y = 2x + 2

Which of the following best describes the solution to the given set of equations

Answers

If you would like to know what best describes the solution to the given set of equations, you can calculate this using the following steps:

y = 2x + 6
y = 2x + 2
____________
y = y
2x + 6 = 2x + 2
6 = 2
6 - 2 = 0
4 = 0 ... no solution

The correct result would be no solution.
