Um i dont think so

Step-by-step explanation:

Answer:You can use the Counting Principle to find probabilities of events. The probability of any event is equal to the ratio of favorable outcomes to the total number of equally likely possible outcomes. Favorable outcomes are the outcomes you are looking for.

Answer:

I only know the answer to number 13, and it is 61°

Step-by-step explanation:

Since I go to RSM, I learned something called a remote interior angle theorem. Basically, the exterior angle is equal to the two angles that are on the far side of the triangle. So if you do 145-74, you get 61°.

Answer: 61°

Answer:

$1.72

Step-by-step explanation:

First, subtract the cupcake from the total

44.03-2.75=41.28

Find out the total number of cookies

8+16=24

Then divide the total cookie price by the total number of cookies

41.28÷24=1.72

Each cookie costs $1.72

Answer:

A

Step-by-step explanation:

- During round 1, Tyler’s group picked 4 purple blocks and 12 blocks of other colors.

0+7=7

1+7=8

2+7=9

3+7=10

4+7=11

5+7=12

We can find patterns.

So the answer would be +7.

Answer:

x=-46/5

Step-by-step explanation:

1. subtract either 5/6 or add 3 for each side.

2. combine terms

3. x=-46/5

Multiply the top number of the fraction by the whole number and then place that over the lower number of the fraction. Then you can see if the new fraction can be reduced or rewritten as a proper fraction.

Example:

1/2 x 3 would be (1 x3) / 2 = 3/2 which can be rewritten as 1 1/2

Example: [tex]\frac{2}{5}*10=\frac{2}{5}*\frac{10}{1}=\frac{20}{5}=4[/tex]

Answer:

100 is the answer

Answer:

RentNSave is 0.05x+2.5 more

Step-by-step explanation:

Answer:

A. 48

B. 24

C. C

Step-by-step explanation:

To divide up whole numbers by fractions, you simply need to just multiply the whole number by the reciprocal of the fraction. in other words, flip the fraction.

Ex.

12 ÷ 1/4

=

12 x 4

Ex. 2

12 ÷ 1/2

=

12 x 2

Answer: the one in 2008 has more higher scores.

Step-by-step explanation:the highest score was 15 and it was in 2008.

Answer:

in 2008 they had a lot of points scored around the same number which was a lower number. However, they had a better season in 2016 because they had more instances where they had 20 points or higher

Step-by-step explanation: I tried my best. Not 100% sure what type of answer you´re looking for.

Answer:

a. (10/40) * (9/39)

Step-by-step explanation:

Since, the total number of white box = 10,

Red box = 10,

Green box = 10,

And, Blue box = 10,

Thus, the total number of boxes = 10 + 10 + 10 + 10 = 40

The probability of receiving white box by first winner =  White box / Total box = 10/40

Since, the replacing is not allowed ( Because, here boxes are allotted )

Thus, the remaining white box = 10 - 1 = 9,

And, the remaining total boxes = 40 - 1 = 39,

Thus, the probability of receiving white box by second winner = Remaining white box / Remaining total box = 9/39

Hence, the probability of the first winner receiving a white box and the second winner also receiving a box of the same color = 10/40 * 9/39

Which is required expression.

Answer:

[tex]\text{Apple juice needed: }40\:\mathrm{oz},\\\text{Cranberry juice needed: }24\:\mathrm{oz}[/tex]

Step-by-step explanation:

Let [tex]a[/tex] be the amount of apple juice needed, in ounces. Let [tex]c[/tex] be the amount of cranberry juice needed, in ounces. We can set up the following system of equations:

[tex]\begin{cases}a=\frac{5}{3}c, \\a+c=64\end{cases}[/tex]

Solving, we get:

[tex]\frac{5}{3}c+c=64,\\\\\frac{8}{3}c=64,\\\\c=\frac{64\cdot 3}{8}=\boxed{24\:\mathrm{oz}}[/tex]

[tex]a=\frac{5}{3}c,\\\\a=\frac{5}{3}(24),\\\\a=\boxed{40\:\mathrm{oz}}[/tex]

Answer:

Step-by-step explanation:

C

Answer:

B)

Step-by-step explanation:

A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.

Answer: Choice B)

3 sides measuring 14 m, 11 m, and 18 m

=================================================

Explanation:

Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.

Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.

Answer:

In lowest terms, there is a 1/3 probability of Jason pulling out a baseball card.

Step-by-step explanation:

There are a total of 6 cards. 4/6 of them are football and wrestling which results in 2 baseball cards. So the probability is 2/6 but since the question wants it in lowest terms, you would have to simplfy 2/6. Divide the top by 2 and the bottom by 2 which gets you 1/3.

Answer:

75

Step-by-step explanation:

Volume = 1/2*B*H

So 10 times 3 times 5 divided by 1/2. 10 times 3 is 30, multiplied by 5 is 150.

150 divided by 0.5 (1/2) is 75.

Find :-

= 1/27

= 1/(3×3×3)

= 1/3³

= 3^(-3)

Veryfication

Our option (c). be like 3^(-4) . 3^7

Now, we explain our ans.

= 3^(-4).3^7

Using Formula

★ a^m × a^n = a^(m + n)

So,

= 3^(-4+7)

= 3^(-3) .

Answer:

40 minutes.

Step-by-step explanation:

First, you divide 30 minutes by 6 miles, so you can see how long it takes to complete 1 mile. It takes 5 minutes. Now, multiply 8 by 5 and you get 40 minutes.

Answer:

30 mins ---- 6 miles

  ? mins ---- 8 miles

30 mins - 6 miles

40 mins - 7 miles

50 mins - 8 miles
