What ratio forms a proportion with 14/42?<br> A. 1/4<br> B. 7/21<br> C. 12/40<br> D. 28/80

koban [17]

Hey there!

"What ratio forms a proportion with $\frac{14}{42}$ ?"

- $\frac{14}{45} =0.56$ (for the decimal)

$A) \frac{1}{4}$ $=0.25$ $(incorrect)$
$B) \frac{7}{21}$ $=0.33$ $(Incorrect)$
$C) \frac{12}{40}$ $0.3$ $(incorrect)$
$D) \frac{28}{80}$ $0.7$ $(incorrect)$

But in order for you to solve this particular equation you'd have to go in with two (like multiplying by two)

$1\times2= 2$ ; $4\times2 = 8$ $(incorrect)$
$7\times 2= 14$ ; $21\times2 = 42$ $(correct)$
$12 \times2 = 24$ ; $40\times 2 = 80$ $(incorrect)$
$2 \times 28 = 56$ ; $2\times 80 = 160$ $(incorrect)$

Your result: $\boxed{Answer: B. \frac{7}{21} }$

Good luck on your assignment and enjoy your day!

Answer:

Boxes at the top are as follows

Monomial. 1. 4x

Binomial. 2. 4x+2

Trinomial. 3.

Polynomial. More than 3.

${5x}^{4} + {2x}^{3} + {12x}^{2} + 135$

This would be an example of a polynomial ^

Omit the next highest term to get a trinomial etc

1. 4th degree. Leading term:

${x}^{4}$

Leading coefficient: x

2. 2nd degree. Leading term:

$- {7x}^{2}$

Leading coefficient: -7x

It's a little confusing to read but that should be everything. Sorry it's not organized better

At a carnival, Ann sold 314 bottles of drinks a day. She sold 66 bottles more in the afternoon then in the morning. How many bot

Paladinen [302]

Answer:

Ann sold 124 bottles of drinks in the morning

Step-by-step explanation:

Let

x ---> bottles sold in the afternoon

y ---> bottles sold in the morning

we know that

Ann sold 314 bottles of drinks a day

so

$x+y=314$ -----> equation A

She sold 66 bottles more in the afternoon than in the morning

so

$x=y+66$ ----> equation B

substitute equation B in equation A

$y+66+y=314$

solve for y

$2y=314-66\\2y=248\\y=124$

therefore

Ann sold 124 bottles of drinks in the morning

A sandwich shop has 70 stores and 90% of the stores are in California. The rest of the stores are in Nevada. How many stores are

horsena [70]

Answer:

For California = 63 stores

For Nevada = 7 stores

Step-by-step explanation:

A sandwich shop has 70 stores and 90% of the stores are in California. The rest of the stores are in Nevada. How many stores are in California and how many are in Nevada?

For California

This is calculated as:

90% of 70 stores

90/100 × 70

= 63 stores

For Nevada

The rest of the stores are in Nevada.

The percent of stores in Nevada = 100 - 90%

= 10%

The number of stores in Nevada

= 10% × 70

= 10/100 × 70

= 7 stores
