A butcher has 15 and 3/4 pounds of steaks and portions them into 7 sealed packs. How many pounds does each pack of steak weigh? *

Answers

Answer:

9/4 or 2 and 1/4 pounds

Step-by-step explanation:

Convert 15 and 3/4 into an improper fraction

15*4+3 = 63

63/4

63/4 ÷ 7

9/4

Thus, each pack weighs 9/4 pounds

Answer:

2 1/4 pounds each

Step-by-step explanation:

Convert 15 1/4 into a decimal (15.75) then divide by seven (15.75 ÷ 7 = 2.25)

and then convert 2.25 back into a fraction, 25 is 1/4 of 100 so the answer is 2 1/4

solve for a, geometry work

Answers

Answer:

a = 45 degrees

Step-by-step explanation:

Since both angles are a, they are equal to each other

Also, we know that the right angle means it measures 90 degrees

So, (180-90)/2 = a

a = 45 degrees

Sum of interior angles in a triangle =180
a+a+90=180
2a+90=180
2a=180-90
2a=90
a=90/2
a=45

Step-by-step explanation:

(3x + 23) + (9x - 6) + 95 + 90 + (7x - 4) = 540

19x + 23 - 6 + 95 + 90 - 4 = 540

19x + 17 + 95 + 90 - 4 = 540

19x + 13 + 185 = 540

Isaac and Albert spot a hot air balloon flying at a low altitude. They decide to calculate its height by standing 400 feet apart on a level surface and measuring the angle of elevation to the balloon. From
Albert, the balloon was at an angle of elevation of 62°and from Issac its was 48º. Determine the height of
the balloon above the ground to the nearest foot.

Answers

Answer:

144 feet to nearest foot.

Step-by-step explanation:

Let the distance between Albert and the point on the ground that the balloon is directly above be x feet Then for Isaac the distance is 400 - x feet

So we have 2 right angled triangles and:

tan 62 = h/x

tan 48 = h / (400- x)         where h is the height of the balloon.

From the first equation x = h / tan 62 so plugging this into the second one:

tan 48 =  h /  ( 400 - h/tan 62)

h = 400 tan 48 - h tan 48 tan 62

h + h tan 48 tan 62 = 400 tan 48

h ( 1 + tan48 tan62) = 400 tan48

h = 400 tan 48 / (1 +  tan 48 tan 62)

= 143.8 feet.

Hey There!

So when finding probabilities we want to find how many even numbers there are and divide that by the amount of numbers

we see that there are 3 even number ( 2, 16 and 8) and there are 8 numbers in total

So in one spin the probability of it landing on an even number is 3/8

Now to find the probability it will land on an even number in 120 spin we multiply 3/8 and 120

[tex]\frac{3}{8} x 120=45[/tex]

So the reasonable prediction of it landing on an even number out of 120 spins is 45
