She has driven 75 miles per hour for 3 whole hours. To find the miles she has driven multiple the miles per hour and the amount of time she has driven. This is 225.
Then she drove 40 miles per hour for only 1 hour. She only drove 40 miles. Add 225 + 40. This gives you 265 miles.
Answer:
(B). 265 miles
Step-by-step explanation:
She travelled 75 mph for 3 hours and 40 mph for 1 hour.
Therefore, 75 + 75 + 75 + 40 = 265 miles

The product of (3+2i) and a complex number is (17+7i)
The complex number is______
Answers
Answer:
The complex number is;
37 + 55i
Step-by-step explanation:
Here, we want to find the product of the two
We proceed as follows;
(3 + 2i)(17+ 7i)
= 3(17 + 7i) + 2i(17 + 7i)
= 51 + 21i + 34i + 14(i)^2
Recall; i = √(-1)
Thus, we have it that;
51 + 55i -14
= 51-14 + 55i
= 37 + 55i

kayak that costs $800. The table shows
Lia'ssavings perweek. Sergio saves
$24 per week. Who will be able to buy
thekayak first? How long willit take?
Answers
Answer:
Sergio will buy first
It will take 34 weeks for Sergio
and 45 weeks for Lia
Step-by-step explanation:
Given Info: Per week Sergio Saves $24
How:
divide $72 by 4 weeks to find how much Lia is earning per 1 week.
72/4= 18
So Lia is saving 18$ per week while Sergio saves $24 per week
24>18
Sergio will save more per week so he will get it first.
It will take 34 weeks for Sergio

[tex]2. \: \: y−4=12[/tex]

Hope it is helpful....step by step explanation:
Inverse operation of addition is subtraction.
a+5=9
-5 -5
a= 4
First thing you want to do is isolate “a”so you have to subtract 5 from both sides of the equation so you can be left with x alone. That will give you a=4
Number 2: is y=16
y - 4 =12
+ 4 +4
y= 16
In this equation the inverse operation of subtraction is addition. So instead of subtracting 4 by both sides of the equation like we did in number one… you will add 4 to both sides of the equation to cancel out the 4 and have “y” by it self.

. If XZ = 7x + 1 and PZ = 4x − 1, what is XP? 11
12 19 22
Answers
Answer:
XP = 11
Step-by-step explanation:
Given that XZ = 7x + 1 and PZ = 4x − 1
From the diagram, XZ = 2PZ
7x + 1 = 2(4x-1)
7x+1 = 8x - 2
7x - 8x = -2 -1
-x = -3
x = 3
Since XP = PZ
XP = 4x - 1
XP = 4(3) - 1
XP = 12-1
XP = 11
UNA POBLACION DE CIERTA CIUDAD EN EL AÑO 2000 ERA DE 250,000 HABITANTES CON UNA TASA DE CRECIMIENTO RELATIVO DEL 2% , DETERMINA LA POBLACION QUE SE ESPERABA PARA EL 2012
Answers
Answer:
La población que se espera para el 2012, es 317,060
Step-by-step explanation:
Si la población tiene un crecimiento relativo del 2%, entonces cada año, la población es un 2% más grande que el año anterior.
Definamos P(t) = población después de t años
Entonces, si al año t = 0 (que corresponde con el año 2000) la población es A
P(0) = A
Un año después, en t = 1, la población incrementa en un 2%
P(1) = A + (2%/100%)*A = A + (0.02)*A = A*(1.02)
Otro año después, en t = 2, la población incrementa un 2% de vuelta.
P(2) = A*(1.02) + (2%/100%)*A(1.02) = A*(1.02) + 0.02*A*(1.02)
= A*(1.02)*(1.02) = A*(1.02)^2
Ya podemos notar un patrón, la población en el año t va a ser:
P(t) = A*(1.02)^t
Sabemos que en t = 0 (el año 2000) la población es 250,000
Entonces A = 250,000
P(t) = 250,000*(1.02)^t
Ahora queremos calcular la población en el año 2012
entonces si t = 0 es el 2000
2012 esta representado con t = 12
Reemplazando eso en la ecuación, obtenemos:
P(12) = 250,000*(1.02)^12 = 317,060.4
Como esto es una población tenemos que redondearlo al próximo número entero, como el primer digito después del punto es 4, redondeamos para abajo.
Entonces la población que se espera para el 2012 es: 317,060

If y varies directly as x, and y is 48 when x is 6, which expression can be used to find the value of y when x is 2
Answers
Answer:
y = 8(2) = 16
Step-by-step explanation:
"If y varies directly as x," then y = kx, where k is the constant of proportionality.
Here, when x = 6, y = 48. This data lets us calculate k:
48 = k*6, or k = 8.
Then the pertinent equation is y = 8x.
If x = 2, y = 8(2) = 16

a) Model this situation with a linear system:
To rent a car, a person is charged a daily rate and a fee for each kilometre driven. When Chena
rented a car for 6 days and drove 320 km, the charge was $286.00. When she rented the same car
for 10 days and drove 900 km, the charge was $605.00.
b) Determine the daily rate and the fee for each kilometre driven.
Answers
Answer:
The daily rate is $ 29 and the fee for each kilometer driven is $ 0.35.
Step-by-step explanation:
Since to rent a car, a person is charged a daily rate and a fee for each kilometer driven, and when Chena rented a car for 6 days and drove 320 km, the charge was $ 286.00, while when she rented the same car for 10 days and drove 900 km, the charge was $ 605.00, to determine the daily rate and the fee for each kilometer driven the following calculation must be performed:
286 = 6 days and 320 km
320/6 = 53,333 km
286/6 = $ 47,666
Thus, the value of 1 day and 53,333 km is $ 47,666.
605 = 10 days and 900 km
900/10 = 90 km
605/10 = $ 60.5
Thus, the value of 1 day and 90 km is $ 60.5.
90 - 53,333 = 36,666
60.5 - 47.666 = 12.833
12,833 / 36,666 = value per kilometer traveled
0.35 = value per kilometer traveled
(286 - (0.35 x 320)) / 6 = X
(286/112) / 6 = X
174/6 = X
29 = X
(605 - (0.35 x 900)) / 10 = X
(605 - 315) / 10 = X
290/10 = X
29 = X
Therefore, the daily rate is $ 29 and the fee for each kilometer driven is $ 0.35.
