Find the measure of each angle indicated
zaharov [31]

Answer:

For #6, it is 81 degrees, and for #8, it is 100 degrees.

Step-by-step explanation:

For #6, it is on the opposite side, so 81 degrees

For #8, it is also on the opposite side, so 100 degrees

Whenever there are parallel lines going horizontally, the angles measure the same on opposite sides, and to find the measure of an angle next to another angle, subtract it from 180.

Make V the subject of the formula E=mv2/2
Dima020 [189]

Answer:

v = ± \sqrt{\frac{2E}{m} }

Step-by-step explanation:

Given

E = \frac{mv^2}{2} ( multiply both sides by 2 to clear the fraction )

2E = mv² ( divide both sides by m )

\frac{2E}{m} = v² ( take the square root of both sides )

v = ± \sqrt{\frac{2E}{m} }

A culture started with 2,000 bacteria. After 2
Ket [755]

Answer: In 10 hours, 4000 bacteria will be present.

Step-by-step explanation:

Given that 2000 bacteria grew to 2400 in 2 hours,

growth/ increase rate = 2400 - 2000

= 400 bacteria increase in 2 hours

Per hour is therefore 400/2 = 200 bacteria increase per hour

If the bacteria increases by 200 per hour

If 200 = 1 hour

X = 10 hours

We cross multiply:

X = 200 x 10

X = 2000

Therefore, a culture with 2000 bacteria at the same growth rate will have increased by additional 2000 in 10 hours

So, after 10 hours, number of bacteria will be 2000 + 2000 = 4000 bacteria

United Express, a national package delivery service, charges a base price for overnight delivery of packages weighing 1 pound or
jonny [76]

Answer:

The correct answer is the base price is $14.50 and surcharge is $2.45 per pound.

Step-by-step explanation:

United Express charges a base price on packages weighing less than or equal to 1 pound and a surcharge for additional pounds.

Let the base price be $b and surcharge be $s.

For a 4 pound package, the customer is billed $21.85. Therefore the equation of his billing looks like b + 3s = 21.85.

For a 19 pound package, the customer is billed $58.60. Therefore the equation of his billing looks like b + 18s = 58.60.

Subtracting both the equation from each other we get 15s = 36.75

⇒ s = $2.45 and b = $14.50.

Thus the base price is $14.50.
