Answer:

For 30 mph it’s 44 feet.

For 60 mph it’s 88 feet.

Step-by-step explanation:

For the 30 mph, you have to divide 30 by 60 (minutes), then you divide it by 60 (seconds). After that, you multiply by 5280 and then you’ll get 44 feet.

For the 60 mph, you have to divide 60 by 60 (minutes), then you divide it by 60 (seconds). After that, you multiply by 5280 and then you’ll get 88 feet.

Plz help me find the measure of each angle indicated. then state the type of angle pair

Makovka662 [10]

19. 60* - a straight line is 180* - the other side which is 120* (supplementary)
20. 132* - the angle below is the same as the other side of this angle, 180* - 48* (same side interior angles)
21. 48* - these are the same angle just in different placements (corresponding angles)
22. 70* - same angles just different placement (alternate interior angles)
23. 85* - these are vertical angles so they’re the same
24. 114* - same angle just different placement (alternate exterior angles)

Which of the following is closest to the area of the shaded region below?

enot [183]

Answer:

C is the answer

Step-by-step explanation:

Find the area of the whole circle, r=12cm

=pie× radius sq

=3.14×12×12

=452.16cm sq

The are of the smaller circle, r=6cm

=same formula

=3.14×6×6

=113.04cm sq

Subtract them to find the area of the shaded region

452.16 - 113.04

=339.12

Radium-226 has a half life of 1622 years. If you start off with a 200

sweet [91]

Answer:

≈23.6 kg left.

Step-by-step explanation:

For determining this, we can simply use an exponential decay equation representing this scenario:

$y= a(0.5)^{\frac{t}{h} }$

a: the initial amount

t: the amount of time

h: the half life

Now, substitute the numbers into the equation:

$y=200(0.5)^{\frac{5000}{1622} }$

Now, solve this equation:

$y=220(0.5)^{3.08}$

Use a calculator to solve for y:

y= 200(0.118)

y≈23.6 kg left.

Chris and Jeff sold 15.5 pounds of trail mix. They sold the trail mix for $3.98 per pound.

Scrat [10]

Answer:

$61.69 You take the 15.5 and take off the .5 to begin with so you start with 15 multiply it by 3.98 to get 59.7 then you take 3.98 divide it by 2 because the .5 is the same thing as 1/2 then you get 1.99 then you add it to your 59.7 to get 61.69 and thats your answer. Hope this helps :)
