a certain map shows two roads. road a is 1 1/4 miles long but is 1 1/2 inches long on the map. what the unit rate for inches per miles on this map? if road b is 10 miles long, how long is road b on the map?

Answers

Answer:

30 inches

Step-by-step explanation:

Length of road A = 1¼ miles

Length of road A on map = 1½ inches

Unit rate for inches per miles on the map = 1½ inches ÷ 1¼ miles = ³/2 ÷ ⁵/4 = ³/2 × ⅘ = ⁶/5 inches per mile

Length big Road B on map:

Road B actual length = 10 miles

Thus, using the unit rate of ⁶/5 inches to 1 mile, length of road B on map would be calculated as shown below:

⁶/5 × 10 = 6*5 = 30 inches

Road B is 30 inches long on the map.

what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6​

Answers

Step-by-step explanation:

(1/3a^2-4b)^6 for such an expansion the general term is

[tex]tr + 1 = \binom{6}{r} \times ( \frac{1}{3} {a}^{2} ) ^{6 - r} \times (4b)^{r} [/tex]

we want b^2 so r=2

so the formula transform to:

C6,2*(1/3)^4*a^8*4^2*b^2 so the coefficient of a^8b^2 is

(6*5/2*1)*(1/3^4)*4^2=

6*5*4*4/2*3*3*3*3=16*5/27=80/27

55.6666666667 as a fraction

Answers

Answer: Step-by-step explanation:

What is 5.56666666667 as a fraction?

To write 5.56666666667 as a fraction you have to write 5.56666666667 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

5.56666666667 = 5.56666666667/1 = 55.6666666667/10 = 556.666666667/100 = 5566.66666667/1000 = 55666.6666667/10000 = 556666.666667/100000 = 5566666.66667/1000000 = 55666666.6667/10000000 = 556666666.667/100000000 = 5566666666.67/1000000000 = 55666666666.7/10000000000 = 556666666667/100000000000

And finally we have:

5.56666666667 as a fraction equals 556666666667/100000000000

Answer:

La opción correcta es;

x² - 4·x·y + 4·y²

Step-by-step explanation:

La ecuación dada es (x - 2·y) ²

(x - 2·y) ² = (x - 2·y) × (x - 2·y) = x·x + x × (-2·y) + (-2·y) × x + (-2·Y) × (-2·y)

Lo que da;

(x - 2·y) ² = x² - x × 2·y - 2·y × x + (-2·y) ²

De lo que tenemos;

(x - 2·y) ² = x² - 2·y × x - 2·y × x + 4·y² = x² - 4·y × x + 4·y²

∴ (x - 2·y) ² = x² - 4·y × x + 4·y² = x² - 4·x · y + 4·y²

Y el resultado del cuadrado simplificado es (x -  ·y) ² = x² - 4·y × x + 4·y² = x² - 4 · x · y + 4·y²

La opción correcta es (x - 2·y) ² = x² - 4·x · y + 4·y².

Step-by-step explanation: 7 x 5 = 35 that is really all you have to do. but this is a random tip always remember that two negitives equal a positve also when you add positve to negitive it goes right so say you have -5 + 5 that would equal zero. when you add negitive and negitve numbers it will have a negitive sum

Which equation shows a proportional relationship between x and y?

y = 16

y = 7x

y=−7x−2

y = 9x + 1

Answers

The equation that shows a proportional relationship is y = 7x.

How to find the equation that is proportional?

Two variables have a proportional relationship if all the ratios of the variables are equivalent.

In other words, a proportional relationship is one in which two quantities vary directly with each other.

Therefore, a proportional relationship can be represented as y = kx.

where

k = constant of proportionalitythe variables are x and y

Therefore, y varies directly as x in a proportional relationship.

Hence, the equation that shows proportional relationship is y = 7x as 7 is the constant of proportionality. y and x are the variables.
