Hey, mate and thanks for letting me help.
$250mi/50mph=5$

Your answer would be 5 hours. Because total time divided by rate is the time it took to travel that distance. 250mi/50mph=5hours. Hope this helps.

PLEASE PLEASE HELP! Find the measure of APB^.

Whitepunk [10]

Answer:

65°

Step-by-step explanation:

Radii CA and CB are perpendicular to tangent lines AT and BT, so

$\angle CAT=\angle CBT=90^{\circ}$

Since angle BAT is equal to 65°, angle CAB has measure

$\angle CAB=90^{\circ}-65^{\circ}=25^{\circ}.$

Consider triangle ACB. This triangle is isosceles, because CA=CB as radii of the circle. Two angles adjacent to the base are congruent, thus

$\angle CBA=\angle CAB=25^{\circ}$

The sum of the measures of all interior angles in triangle is always 180°, so

$\angle CAB+\angle CBA+\angle ACB=180^{\circ}\\ \\25^{\circ}+25^{\circ}+\angle ACB=180^{\circ}\\ \\\angle ACB=130^{\circ}$

Angle ACB is central angle subtended on the minor arc AB, angle APB is inscribed angle subtended on the same minor arc AB. The measure of inscribed angle is half the measure of central angle subtended on the same arc, so

$x=\angle APB=\dfrac{1}{2}\cdot 130^{\circ}=65^{\circ}$

Which of the following points lies on the graph of the function y= 2.3*?

Rainbow [258]

If the equation is $y = 2\cdot 3^x$ (2 times 3^x)

Then the answer is d. (0,2)

This is because plugging x = 0 leads to y = 2 as shown below

$y = 2\cdot 3^x\\\\y = 2\cdot 3^0\\\\y = 2\cdot 1\\\\y = 2$

Please help me with this

N76 [4]

Answer:

ASA

Step-by-step explanation:

One pair of corresponding angles (in the bottom left/right) are already marked for us, and we're also given a pair of corresponding sides (the 8cm ones on the left and right). The two triangles have one more angle in common too - the one they're overlapping on the top corner. So, we have:

- Two pairs of congruent corresponding angles, and

- A pair of congruent corresponding sides between them,

which is enough information to call the triangles congruent by Angle-Side-Angle (ASA).

Natalia and Daphne are on the math team. In the last competition, Natalia answered 5 questions more than Daphne, and together th

zvonat [6]

Answer: Natalia answered 11 questions while Daphne answered 6

Step-by-step explanation:

Well... 17-5 (the total amount of questions minus the number of more questions Natalie answered) equals 12 which you will divide by 2 because there are 2 girls, will get Daphnes amount of questions answered (6) and then basically Natalia answered 11
