The cost of a daily rental car is as follows: The initial fee is $69.99 for the car, and it costs $0.30 per mile. If John initially pays $200.00 before taxes and does not want to exceed that amount, how many miles can he drive?

x ≥ 433 miles
x = 450 miles
x ≥ 450 miles
x ≤ 433 miles

Answers

x [tex]\geq[/tex] 433

explanation:

let m equal miles

0.30m + 69.99 = 200

-69.99 -69.99

0.30m = 130. 01

130.01 / 0.30 = 433. 36...

but we're gonna round it to 433

so 433 miles

If each soda sells for $2.50, what is the expected daily total dollar amount taken in by the vendor from the sale of sodas?

Answers

Answer:

$34.38

Step-by-step explanation:

Y: A random variable that indicates the amount of money that the seller will receive.

p=2,50$

if x=0 → y=0.2,50=0$

if x=5 → y=5.2,50 = 12,5 $

if x=10 → y=10.2,50= 25$

if x=15 → y=15.2,50= 37,5$

if x=20 → y=20.2,50= 50 $

if x=25 → y=25.2,50= 62,5$

Y= { 0$ ; 12,5$ ; 25$ ; 37,5$ ; 50$ ; 62,5$ }

E(Y)= ∑Y.P(Y)

= 0.P(0)+12,5.P(12,5)+ 25.P(25)+ 37,5.P(37,5)+ 50.P(50)+ 62,5.P(62,5)

= 0.0,01+ 12,5.0,15+ 25.0,25+ 37,5.0,3+ 50.0,25+ 62,5.0,04

= 0 + 1,875 + 6,25 + 11,25 + 12,5 + 2,5

= 34,38$ expected value of the amount of money the seller receives.

Element X decays radioactively with a half life of 6 minutes. If there are 260 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 113 grams

Answers

Answer:

7.2 minutes

Step-by-step explanation:

The formula to find the time using the radioactive decay rate formula is given as:

t = t½ × In(Nt/No)/-In2

Where

t½ = half life = 6 minutes

No = Initial Amount = 260 grams

Nt = Amount after decay

= 113 grams

Hence:

t = 6 × In(113/260)/-In2

t = 7.2131331036796 minutes

Approximately = 7.2 minutes

A rectangular table top has dimensions as 1.52m and 0.75m. Find the perimeter in cm

Answers

That is a question about perimeter of rectangle.

The perimeter of a geometric shape is the sum of the value of the all sides.

In a rectangle, the opposite sides are cogruentes (equals). For example, look at picture below. In that rectangle, the sides AB and DC are equals, and the sides AD and BC are equals.

So, the sides of that rectangular table are: 1.52m, 1.52m, 0.75m and 0.75.

Therefore, the perimeter of that rectangle is [tex]1.52+1.52+0.75+0.75= 4.54[/tex]m.

But that is not the final answer because that is the perimeter in meters and the question want the answer in centimeters.

1 meter has 100 centimeter, so we need to multiplicate the perimeter by 100.

Thus, the perimeter of that rectangular table is [tex]4.54\cdot 100 = 454[/tex]cm.

The history of their construction spans both ancient and modem times.ThenBuilt around 1250 B.C.E., the Great Temple of Ramses II and the smaller Temple of Hathor next to it were carved out of a mountainside. This was no easy job. Four 67-foot-high statues of Ramses flank the entrance to the Great Temple. Inside, three inner chambers extend two hundred feet into the rock. The ancient Egyptians excavated these rooms and their massive columns using, of course, only hand tools. They also used detailed calculations to carefully align the temple. As a result, at dawn on two days of the year, sunlight reaches into the third chamber. This room was a sacred sanctuary, containing the statues of four gods. The sun's rays light up the statues and symbolically awake them to life.NowIn the 1960s, Egypt built the High Dam to control the annual Nile floods. The lake that formed behind the dam would have covered the temples at Abu Simbel. Archeologists from Egypt and many other countries were alarmed, so they raised funds to move the mountainside. And that is what was done. Workers using handsaws cut the two temples into more than a thousand blocks. Each block weighed from 10 to 40 tons. The blocks were carried to safe ground 195 feet higher. Engineers then rebuilt the two temples inside a man-made concrete mountain. They were careful to place the Great Temple in the exact orientation of the original so that the gods of the sacred sanctuary are still awakened twice a year. This reconstruction was nearly as huge a feat as that of digging the temples from the rock in the first place.Select the correct answer.According to the author, why should a tourist go to Abu Simbel?A. The temples are a feat of ancient engineering.B. The temples are a feat of modern engineering.C. The temples are a feat of both ancient and modern engineering. Compre muchas cosas Ayer.
