Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80

Determina la EPG que adquiere una trapesista de 52 kg de masa cuando sube a un trapecio de 8 metros de altura. Considera g=9.81
Answers
Responder:
4080,96 Julios
Explicación paso a paso:
La energía potencial gravitacional adquirida se puede obtener mediante la relación:
EPG = masa * aceleración por gravedad * altura
Masa = 52 kgb; aceleración debida a la gravedad = 9,81; h = 8 metros
EPG = 52 * 9,81 * 8
EPG = 4080,96 julios

X-3 and passes

Answers
Answer:
y = 1/2x + 4
Step-by-step explanation:
If it's parallel, then the slope will remain the same.
To find the y-intercept, you have to plug the coordinates into the equation.
y = 1/2x + b
6 = 1/2 (4) + b
6 = 2 + b
4 = b

SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?
Answers
Answer:
14 son varones
Step-by-step explanation:
Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total
45 + 35 = 80
60 de ellos viven en el Distrito de Breña entonces los descontamos del total
80 - 60 = 20
Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70
20 * 0.70 = 14
Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

What interval consists of all $u$ such that neither $2u$ nor $-20u$ is in the interval $(-\infty,-1)$ ?
Answers
Answer:
[-1/2,1/20]
Step-by-step explanation:
Answer:
[-1/2,1/20]
Step-by-step explanation:
In terms of inequalities, we are asked to find all $u$ such that $2u\ge -1$ and $-20u\ge -1$.
The solution to the first inequality, obtained by dividing both sides by $2$, is $u\ge -\frac{1}{2}$.
We can solve the second inequality by dividing both sides by $-20$, but because we are dividing by a negative number, we must reverse the direction of the inequality: $u\le \frac{1}{20}$.
The set of $u$ which satisfy both inequalities simultaneously is thus $\boxed{\left[-\frac{1}{2},\frac{1}{20}\right]}$.

A population of llamas stranded on a desert island is decreasing due to a food shortage by 6% per year. If the population of llamas started out at 350, how many are left on the island 10 years later?
Answers
Answer:
189
Step-by-step explanation:
Given data
Initial population=350
Rate = 6%
TIme= 10 years
Let us apply the compounding expression
A=P(1-r)^t----------The negative sign is due to decreasing value
substitute
A= 350(1-0.06)^10
A=350(0.94)^10
A=350*0.5386
A=188.51
Hence the approximate population will be 189

Answers
Answer:
D. 11 feet 11 inches
1 foot= 12 inches
143/ 12 = 11 11/12
Answer:
D) 11 feet and 11 inches
Step-by-step explanation:
First we know that there is 12 inches in a foot. So let's start with a.
14 inches x 12 inches (one foot) is 168 inches (so it's not this one:)
13 inches x 12 inches is 156 inches (It's not this one either)
12 inches x 12 inches is 144 inches (not this one)
11 inches x 12 inches is 132 inches (so it could be this one, let's add the remaining inches).
132 + 11 inches = 143 inches.
(Notice I didn't add the remaining inches on A, B, or C because the number of inches was already too much. I did on D because the number of inches was below the given number of 143.
