At Billy's school, 80 students come to school by bicycle or by car. Together, the vehicles they arrive to school in have 270 whe

Anna35 [415]

Answer:

x = number of bicycles = 35

y = number of cars = 55

Step-by-step explanation:

Let

x = number of bicycles

y = number of cars

x + y = 80 (1)

2x + 4y = 270 (2)

From (1)

x = 80 - y

Substitute x = 80 - y into (2)

2x + 4y = 270 (2)

2(80 - y) + 4y = 270

160 - 2y + 4y = 270

- 2y + 4y = 270 - 160

2y = 110

y = 110/2

y = 55

Substitute y = 55 into (1)

x + y = 80 (1)

x + 55 = 80

x = 80 - 55

x = 35

x = number of bicycles = 35

y = number of cars = 55

Use the given graph to determine the limit, if it exists. A coordinate graph is shown with a downward sloped line crossing the y

vesna_86 [32]

For the limit approaching 3 from the right, you want to follow the line to the right of x = 3. From the graph you're describing it sounds like that's y = -3. $\lim_{x \to 3} f(x)=-3$

The RHS limit is -3 even though f(3) = 7

A. Suppose you have just inherited a sum of money. Let’s say you choose to invest the money. How much did you inherit? Choose an

leva [86]

Amount =$48003.20

Step-by-step explanation:

Here apply the compound interest formula;

$A=P(1+\frac{r}{n} )^{nt}$

where;

P=Principal amount invested = $37500

r=rate of interest as a decimal, 2.5% =0.025

n=number of compounding per year=1

t=time period the amount in invested=10

In our case, the amount after investing will be;

$A=37,500(1+0.025)^{10} \\\\A=37,500(1.025)^{10} \\\\A=48003.20$

Interest earned after the period= $48003.20-$37500 =$10503.20
