Answers

Answer 1

Answer:

Answer:

yes because the one on top is larger than the number on the bottom

Answer 2

Answer:

Answer:

2 2/9

Step-by-step explanation:

20/9 = 2 2/9

36 x 2 = 72

80 - 72 = 8/36

2 8/36 = 2 2/9

Manny makes dinner using 1 box of pasta and 1 jar of sauce. If pasta is sold in packages of 10 boxes and sauce is sold in packages of 2 jars, what is the least number of dinners that Manny can make without any supplies leftover?

Answers

Answer:

10 dinners

Step-by-step explanation:

We solve using the Least Common Multiple Method.

We are told:

Pasta is sold in packages of 10 boxes Sauce is sold in packages of 2 jars.

We find the Multiples of 2 and 10

Multiples of 2:

2, 4, 6, 8, 10, 12, 14

Multiples of 10:

10, 20, 30

Therefore,

LCM(2, 10) = 10

The least number of dinners that Manny can make without any supplies leftover is 10 dinners

What is the measure of this angle? Choose the best estimate.135°
30°
60°
90°

Answers

Answer: 135°

Step-by-step explanation:

We see that this angle looks to be greater than 90°. A 90°-angle is like one corner of a square. Since this angle is greater than 90 degrees, we can estimate the angle is 135° since it's the only one greater than 90° because 90° > 60° > 30°.

Patty is 50 mi. due north of Todd. Emma is due east of Todd. The angle between the direction of the shortest distance from Emma and Patty and due east is 40°. To the nearest mile, how far is Emma from each person?

Answers

For this it would be helpful if you draw a diagram of the situation. You will see that a right triangle can be formed from the problem. We use trigonometric functions to solve. We do as follows:

sin 40 = 50/y
tan 40 = 50/x

Solving we obtain,
x = 60 mi
y = 78 mi

Hope this answers the question. Have a nice day.

Answer:

Hence, the distance between Todd and Emma is:41.955 mi.

and the distance between Patty and Emma is:32.14 mi.

Step-by-step explanation:

We will see that we will get a right angled triangle based on our information(The graph is attached to the answer)

Now let x denotes the distance between Emma and Todd.

and y denotes the distance between Emma and Patty.

Now as the triangle is right angled so we can use the trignometric identities to find the distance.

$\tan40\degree=(50)/(x)$

this means $x=\tan40\degree * 50$

Now as $\tan40\degree=0.8391$

Hence, $x=41.955 \text{mi.}$

Similarly,

$\sin40\degree=(50)/(y)$

Hence $y=32.14 \text{mi.}$

There are 12 students in a classroom, including the triplets joey, chloe, and zoe. If 3 of the 12 are randomly selcted to give speeches, what is the probability that joey with be first, chloe will be second, and zoe will be third?A: 1/1320 B: 1/4 C: 1/48 D: 1/220

Answers

The probability of choosing Joey first is 1/12 .

If that happens, the probability of choosing Chloe next is 1/11 .

Then, the probability of choosing Zoe after that is 1/10 .

The probability of all these things happening is

(1/12) x (1/11) x (1/10)

= 1/1320 = 0.00076 = 0.076 percent

You are at a stall at a fair where you have to throw a ball at a target. There are two versions of the game. In the firstversion, you are given three attempts, and you estimate that your probability of success on any given throw is 0.1.In the second version, you are given five attempts, but the target is smaller, and you estimate that your probability ofsuccess on any given throw is 0.05. The prizes for the two versions of the game are the same, and you are willing toassume that the outcomes of your throws are independent. Which version of the game should you choose? (Hint: Inthe first version of the game, the probability that you do not get the prize is the probability that you fail on all threeattempts.)
