Answer 1

Answer:

B ( 92 degrees)

Step-by-step explanation:

1. Find y

In order to find z, we need to find y.

All triangles add up to 180 degrees, so y would be

180 - (48 + 44) = 88

y is 88 degrees

2. Find z

So now we know y is 88, we can find z

The circle of all angles of y and z = 360 ( because full angle)

so our equation is:

(88 + z)2 = 360

Divide by 2

88 + z = 180

z = 92

Answer 2

B (92) is the answer

A circle with a 12 inch diameter is folded in half and then folded in half again. What is the approximate area of the resulting shape? and what is the exact area of the shape?

4.$43

Answer:

1.) $35

2.) $36

3.)$51

4.)$43

Step-by-step explanation:

1.)30% of 50 is 15 and you would subtract the 15 from 50 to get your discount.

2.)55% of 80 is 44 and you would subtract 44 from 80 to get your after price.

3.)For this one, I divided the discount price by 3 and multiplied it by 4 to get the original price since 1/4 was taken from it or 25%.

4.) There was only one option left.

#1. It costs $0.001 per hour to run a light bulb. How much does it cost to run each light bulb per month?
#2. The winner of the biggest loser lost 0.952 ounces per hour. How many pounds did they lose per week?
#3. Falcons can dive at a speed of up to 318 feet per second. How many miles per hour can they dive?

Answers

Answer:

#1 It costs $0.73 to run each lightbulb per month

#2 They lost 9.996 pounds per week

#3 They can dive 3.61363636 miles per hour

Step-by-step explanation:

#1 There are 730 hours in a month. Multiplying that by 0.001 gives $0.73.

#2 There are 168 hours in a week. Multiplying that by 0.952 gives 159.936 ounces. 159.936 ounces = 9.996 pounds

#3 One minute equals 60 seconds. 318x60 gives 19,080 feet. 19,080 feet converted gives 3.61363636 miles

a) In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?

Answers

Answer:

233.53 s

Step-by-step explanation:

The sum of best times for the legs is ...

56.81 +59.22 +57.39 +60.11 = 233.53 . . . seconds

Without additional information about the effects of training or the normal variation in times, this is the best prediction we can make.

What's the banana worth?

Answers

Answer:

Step-by-step explanation:

Looking at the first one, you have three watermelons. 36/3 is 12, so one watermelon is worth 12!

With the second one, you subtract 12 from 28 to get 16. Since there are two (peaches?), you divide 16 by two to get the peaches worth, which is 8.

That leaves you with the last one. I used the simple "8 - __ = 3", which got me the answer, 5.
