Answer:
3.75mph, or 0.0625 miles a minute
Step-by-step explanation:
12 times 5 is 60
.75 times 5 is 3.75
so he was walking mathematically 3.75 miles per hour
Answer:
3.75 mph
Step-by-step explanation:
12 minutes is 0.2 hours
0.75/0.2 = 3.75 mph
what is the coefficient of a^8b^2 in the expansion (1/3a^2 - 4b)^6
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

hey can anyone pls answer dis math question rq!
Answer:
9 inchesStep-by-step explanation:
Original size = 6 ftScale factor = 1/8Clone = original * scale factor
Clone size
6 ft*1/8 = 3/4 ftConverted to inches
1 ft = 12 in3/4 ft = 3/4 * 12 in = 9 ina 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?
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.
55.6666666667 as a fraction
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

Which equation shows a proportional relationship between x and y?
y = 16
y = 7x
y=−7x−2
y = 9x + 1
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 yTherefore, 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.

(-7) · (-5)
-12
-35
12
35
Answer:
35
Step-by-step explanation:
A negative number multiplied by a negative number is positive. Multiplication is repeditive addition.
(-7) * (-5) = -(-7 + -7 + -7 + -7 + -7) or -( -5 + -5 + -5 + -5 + -5 + -5 + -5 ) = 35.
Answer:
35 is the answer I remember my brother telling me that two negitives always makes a positive no matter the symbol
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

The answer is 52
How do you solve this?
Answer:
145
Step-by-step explanation:
180-137=43
43+102=145
Answer The answer is 145 because, as you see you need a 180 degree angle, so you have 137 and you need to make those two angles 180 so 180-137=43 so then you got 43+102 so that's 145 then you have that other angle so that'll be 35, so the ? mark will be 145 since that 180-35

Efectuar el cuadrado de un binomio: ( x – 2y ) ^2 =Respuesta necesaria. Opción única.
(1 Punto)
x^2 – 4xy + 4y^2
x^2 + 4xy + y^2
x^2 – 4y^2
x^2 – 2xy + 4y^2
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.
