35+5t=amount in tank A after t minutes
100-8t=amount in tank B after t minutes

same amount

35+5t=100-8t
add 8t both sides
35+13t=100
minus 35 both sides
13t=65
divide by 13 both sides
t=5
5 minutes

Help with stats! A poll asked the question, "What do you think is the most important problem facing this country today?" Sixteen

Stolb23 [73]

<span>"What do you think is the most important problem facing this country today?"

16% of the respondents answered

"crime and violence."

The margin of sampling error was plus or minus 3%

Following the convention that the margin of error is based on a 95% confidence interval, find a 95% confidence interval for the percentage of the population that would respond "crime and violence" to the question asked by the pollsters.

hmmm, im thinking this looks familiar to me, but ill have to see whats wrong about it first

using .16 as p^ and therefore 1-p^ = q^ = .84</span>

We have a bilateral triangle with base length 2 and sidelengths x where x is increasing at a rate

BaLLatris [955]

Answer:

$\frac{5\sqrt{3} }{6}$

Step-by-step explanation:

Given :

base length = 2

side lengths = x

dx/dt = 5 unit/min

Determine d∅ / dt at x = 2

d∅ / dt at x = 2 = $\frac{5\sqrt{3} }{6}$

attached below is a detailed solution

Which statement is correct regarding the measurements of the parallelogram? On a coordinate plane, a parallelogram has points (1

spayn [35]

Answer:

Step-by-step explanation:

Let's plot these points (see diagram).

The base is the horizontal length of the parallelogram, while the height is the the perpendicular distance from the top base to the bottom base.

We can see from the graph that the base is 8 units and the height is 3 units. The area of a parallelogram is A = bh, where b is the base and h is the height. Here, the base is 8 and the height is 3, so the area is A = 8 * 3 = 24 square units.

The answer is B.
