ACUTE ANGLE.
this is because the angle is less than 90 degree and greater than 0 degree

This Is An Acute Angle.
You Know This Because:
Acute Angles Are Angles That Measure Less Than 90 Degrees.
A Right Angle Is An Angle That Measures Exactly 90 Degrees
An Obtuse Measures More Than 90.

65% of the 800 students at North High School ride the

jonny [76]

Answer:

520 out of 800 students ride the bus

Step-by-step explanation:

Given

$Proportion = 65\%$

$Students = 800$

Required

Determine the number of students $that\ ride\ the\ bus$

To do this, we simply multiply the proportion by the total number of students.

i.e.

$Bus = Proportion * Students$

$Bus = 65\% * 800$

Express the percentage as decimal

$Bus = 0.65* 800$

$Bus = 520$

Evaluate lim x=π/4(3x - tanx)

Karo-lina-s [1.5K]

Answer:

$\lim_{x \to\frac{\pi }{4} } (3x-tanx)$ = $3(\frac{\pi }{4} )$

Step-by-step explanation:

Explanation:-

Given that

$\lim_{x \to\frac{\pi }{4} } (3x-tanx)$

= $\lim_{x \to\frac{\pi }{4} } (3x) - \lim_{x \to\frac{\pi }{4} } tanx)$

= $3(\frac{\pi }{4} )+tan(\frac{\pi }{4} )$

= $3(\frac{\pi }{4} )+ 1 )$

= $3(\frac{\pi }{4} )$

WILL mark brainliest!

Angelina_Jolie [31]

Answer:

110.5348 minutes

Step-by-step explanation:

The difference from room temperature changes from 103 to 59 in 46 minutes, so that difference can be modeled by the exponential equation ...

Δt = 103×(59/103)^(t/46)

We want to find t for the temperature difference Δt = 91 -64 = 27.

27 = 103×(59/103)^(t/46)

27/103 = (59/103)^(t/46) . . . . . divide by 103

Taking logs gives the linear equation ...

log(27/103) = (t/46)log(59/103)

Multiplying by the inverse of the coefficient of t, we get ...

t = 46·log(27/103)/log(59/103) ≈ 46·(-0.58147346)/(-0.24198521)

≈ 110.5347

It will take about 110.5347 minutes for the turkey to cool to 91 °F internally.

Comment on 4 decimal places

An answer correct to 4 decimal places (7 significant digits) is a pretty good indication that the problem was worked correctly. However, that level of precision in the timing makes little sense in this context. Most thermometers will take at least a few seconds to register the temperature to within a tenth of a degree or so. This problem is asking for an answer that is within 6 milliseconds and 30 micro-degrees. Neither of these is anywhere near realistic for a kitchen meat thermometer.

More realistic would be an answer to 4 significant figures, a tenth of a minute and a few hundredths of a degree.

(The rate of change at the time of interest is about -0.33 degrees per minute.)
