Answer: I could be wrong but it's probably 3.

Step-by-step explanation: Once there's x in the 3 sides of angles you subtract. 73 minus 3 = 3 degrees. If I'm wrong sorry about that. I will try to improve. :)

Answer:

37°

Step-by-step explanation:

70°+73°+x°=180°

143°+x°=180°

x°=180°-143°

x°=37°

Answer:

[tex]a = \frac{1}{134217728}[/tex]

Step-by-step explanation:

Given

[tex]8^x = a^{-x/9}[/tex]

Required

Find a

Take log of both sides

[tex]log(8^x) = log(a^{-x/9})[/tex]

Apply law of logarithm

[tex]x\ log(8) = (-x/9) log(a)[/tex]

Divide both sides by a

[tex]log(8) = -\frac{1}{9} log(a)[/tex]

Multiply both sides by -9

[tex]-9\ log(8) = log(a)[/tex]

Apply law of logarithm

[tex]log(8^{-9}) = log(a)[/tex]

Cancel out log

[tex]8^{-9} = a[/tex]

Rewrite as:

[tex]a = 8^{-9}[/tex]

Apply law of indices

[tex]a = \frac{1}{8^9}[/tex]

[tex]a = \frac{1}{134217728}[/tex]

Answer:

1000 children

Step-by-step explanation:

Find the total units of adults and children = 2 + 3 = 5

5 units = 5000

1 unit = 5000 ÷ 5 = 1000

100% ÷ 5 units = 20% each unit

3 units = 20% x 3 = 60%

Since we all know that 60% of the people are children and 40% of the children are girls...

60 - 40 = 20%

20% = 1000

Answer:

Jose will have played the guitar for 9.1 hours during those 6 days.

Step-by-step explanation:

Given that this week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday, to determine, if Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days, the following calculation must be performed:

3/4 = 0.75

1/2 = 0.5

(0.75 + 1.5 + 2.3) x 2 = X

4.55 x 2 = X

9.10 = X

Therefore, Jose will have played the guitar for 9.1 hours during those 6 days.

Answer:

D Not similar

Step-by-step explanation:

For similar triangles the sides are always in proportions.

Here two sides are in proportion but third side isn't. So triangles are not similar.

Answer:

No Duwan is in incorrect.

Step-by-step explanation:

When it asks for a number to be 10x greater, the answer would be in a digit that is 1 greater. For example 10x greater than 10 would be 100. You move the digit up once. An answer that Duwan could have used is: 260,000.

Answer:

The answer is D,

a(n) = 4/5 + 1/6(n- 1)

just took the test :)

Step-by-step explanation:

The explicit formula for the arithmetic sequence is D, a(n) = 4/5 + 1/6(n- 1)

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

The explicit formula is given by:

[tex]T_n = a + (n-1)d[/tex]

Where a is the first term (4/5) and d is the common difference (the difference is any 2 terms).

Therefore, to find d:

29/30 - 4/5

29/30 - 24/30

d = 5/30

d = 1/6

Now putting them into the formula:

a(n) = 4/5 + 1/6(n- 1)

The last answer choice is right.

#SPJ2

Answer: x = 12

Step-by-step explanation:

subtract 8 on both sides (12-8=4)

now we have 1/3x = 4

multiply 3 on both sides (4 x 3 = 12)

now we have x = 12

1. x=-2, x=0

So, the equation in factored form would be x(x+2)=0.

2. x=0, x=4

So, the equation in factored form would be x(x-4)=0.

3. x=-2, x=0, x=4

So, the equation in factored form would be x(x+2)(x-4)=0.

Answer:

AB = 7.10

Step-by-step explanation:

Reference angle = 65°

Hypotenuse = AB = ?

Adjacent side length = BC = 3

Apply the trigonometric ratio CAH, to find AB.

Cos 65 = Adj/Hyp

Cos 65 = 3/AB

AB*Cos 65 = 3

AB = 3/Cos 65

AB = 7.09860475

AB = 7.10 (nearest hundredth)

Answer:

10

Step-by-step explanation:

Let's find f(2) first.

f(2) = 2 + 2 = 4

This means it would be f(g(4)).

Then let's find g(4).

g(4) = 4 + 4 = 8

Then, this means f(8).

f(8) = 8 + 2 = 10

Answer: 9/1

Step-by-step explanation: Apologies for the mistake. Let's calculate the probability again.

To find the probability of rolling a sum of 9 on two number cubes, we need to determine the number of favorable outcomes and divide it by the total number of possible outcomes.

For a sum of 9, the following combinations are favorable:

(3, 6), (4, 5), (5, 4), (6, 3)

So, there are 4 favorable outcomes.

The total number of possible outcomes is still 6 × 6 = 36.

The probability of rolling a sum of 9 is:

Probability = Number of favorable outcomes / Total number of possible outcomes

Probability = 4 / 36

Simplifying the fraction, we get:

Probability = 1 / 9

Therefore, the probability of rolling a sum of 9 is 1/9, not 11/18 as previously stated.
