Two cars were at a gas station, a red car and a blue car. The red car filled up with 12 gallons of gas and was able to travel. The blue car filled up with 15 gallons of gas and was able to travel 330 miles. What was the gas mileage of each car? Which car got better gas mileage?
Answer:
Red Car Gas mileage:
= Distance travelled/ Gas used
= 300/12
= 25 mpg
Blue Car gas mileage:
= 330/15
= 22 mpg
The car with the better mileage is the one that goes further per gallon of gas which is the Red Car.

Una nadadora entrenó todos los días durante 21días. El primer día nadó 15 minutos, y cada día nadaba 5 minutos más que el día anterior. ¿Cuánto tiempo nadó el último día? ¿Y a lo largo de las tres semanas? Expresa los resultados en horas y minutos.
Responder:
1 hora 55 minutos; 22 horas 45 minutos
Explicación paso a paso:
Dado que:
Tiempo el primer día = 15 minutos
Minutos adicionales cada día siguiente = 5 minutos
Número total de días
Usando la fórmula del enésimo término de una progresión aritmética:
Tn = A + (n - 1) d
A = primer trimestre = 15
d = diferencia común = 5
n = enésimo término
Tiempo de nado el último día (n = 21)
T21 = 15 + (21 - 1) 5
T21 = 15 + 20 * 5
T21 = 15 + 100
T21 = 115 minutos
= 1 hora 55 minutos
SEGUNDO.)
Suma de minutos durante las 3 semanas
Suma de n términos:
Sn = n / 2 * (primer término + último término)
Primer término = 15
Último trimestre = a21 = 115 minutos
n = número de términos = 21
Por lo tanto,
Sn = 21/2 * (15 + 115)
Sn = 10,5 * (130)
Sn = 1365 minutos
= 22 horas 45 minutos

(1,2) (1,8) (3,6) (4,8) is it a function?
Answer:
No, because the x value of 1 correlates to two different y values.
Step-by-step explanation:
A function is defined by an x value having exactly one corresponding y value. In this case, the x value of 1 corresponds to both the y values of 2 and 8, therefore invalidating it as a function.
Hope this helps!
Answer:
No, this table is not a function.
Step-by-step explanation:
[tex]x: 1, 1, 3, 4\\y: 2, 8, 6, 8[/tex]
In the x column, you can see two one's [tex](1)[/tex]. Also, in the y column, you can see two eight's [tex](8)[/tex].
what is the slope-intercept form of a line
In circle G with m \angle FGH= 82m∠FGH=82 and FG=7FG=7 units, find the length of arc FH. Round to the nearest hundredth.
The arc length of FH from the given circle is 10.1108 square units.
In the given circle, m∠FGH=82° and FG=7 units.
The formula to find the arc length of a circle is θ/360° ×2πr.
Here, θ=82° and r=7 units
Now, arc length = 82°/360° ×2×3.14×7
= 0.23×2×3.14×7
= 10.1108 square units
Therefore, the arc length of FH from the given circle is 10.1108 square units.

Bill's Apparel and Bud's Apparel are two sporting goods retailers. Bill's want to buy 360 small jerseys, 540 medium jerseys, and 300 large jerseys, while Bud's want to buy 240 small jerseys, 600 medium jerseys, and 360 large jerseys. The two dealers from which they are looking to buy their jerseys are Zest Athletics and Zeal Sporting Wear. Zest charges $14 for small jerseys, $18 for medium jerseys, and $21 for large jerseys. Zeal charges $16 for small jerseys, $18 for medium jerseys, and $19 for large jerseys. Use matrix multiplication to find the dealer each retailer should choose for its purchase.
Answer:
D
Step-by-step explanation:
Doing the math, For Bill's to buy it's clothes from Zest, it would take $21060,
while it would take $21180 from Zeal. So Bill's wants Zest.
Bud's price for Zest is $21720, and for Zeal is $21480. Bud's Wants Zeal.
Bill should purchase from Zest and Bred should purchase from Zeel.
What is matrix multiplication?
Matrix multiplication is a binary operation that creates a matrix from two matrices in mathematics, especially in linear algebra. The first matrix's columns must have the same number of rows as the second matrix's rows in order for matrices to be multiplied.
Bud's Apparel and Bill's Apparel are two stores that sell athletic items. In contrast to Bud, who wants to purchase 240 small jerseys, 600 medium jerseys, and 360 large jerseys, Bill wants to purchase 360 small jerseys, 540 medium jerseys, and 300 large jerseys. They are looking to purchase their jerseys from Zest Athletics and Zeal Sporting Wear, respectively. Small, medium and large jerseys cost $14, $18, and $21, respectively, from Zest. Small, medium and large jerseys cost $16, $18, and $19, respectively, from Zeal. From matrix multiplication.
For bill,
if bill buys from zest: 14* 360 + 18* 540 +21*300 = 21060
if bill buys from zeel: 16*360 + 18* 540 + 19*300 = 21180
Since 21060<21180
thus bill should buy from the zest
For bud
if bud buys from zest: 14* 240 + 18* 600 +21*360 = 21720
if bud buys from zeel: 16*240 + 18* 600 + 19*360 = 21480
Since 21720 > 21480
thus bud should buy from the zeal
Therefore, Bred should buy from Zeel, and Bill should buy from Zest.

A globetrot contains 3 red balls, 2 green balls and 6 blue balls if we choose a ball then another ball without putting the first one back in the globetrot what is the probability that the first ball will be redundant the second ball will be blue?
Answer:
9/55
Step-by-step explanation:
I don’t like explaining :/ If this is wrong I’m terribly sorry :(
Answer:
Prob = (3 / 11) * (6 / 10) = 18 / 110 = 9 / 55
Step-by-step
The probability that the first is red equals 3/11 (favourable outcomes divided by possible outcomes). Under condition that this occurs the probability that the second is blue equals 6/10. The probability of the described event is then the product of these factors. This according to the rule P(A and B)=P(A)*P(B|A).
