Answer:

sin θ = 12 / 13

Step-by-step explanation:

Given that :-

A right triangle having

Hypotenuse = 13

adjacent side ( Base ) = 5

Opposite side ( perpendicular ) = ?

To Find :-

sin θ

Solution :-

Firstly ,we need to find opposite side ( missing side ) of triangle

Using Pythagorean theorem

a ² + b ² = c ²

Where, a and b is the base and c is the height of triangle.

substitute the value

( 5 ) ² + ( b) ² = ( 13 ) ²

evaluate the exponent

25 + b² = 169

subtract 25 from each side

25 - 25 + b² = 169 - 25

b ² = 144

Take the square root of each side

√b² = √144

b = 12

Hence , opposite side , b = 12

And , Finding sin θ

sin θ = opposite side / hypotenuse

sin θ = 12 / 13

Alright let’s help you understand this time. So if you look at the board on the ruler. It passes through 1 inch and then 2 inches. But it doesn’t go to 3 inches. So the answer will be 2 inches and something. The board’s end is in between 2 inches and 3 inches, so it would be half, which is 1/2.

Karim had a packet of 200 chocolates. He gave 35% of them to his sister. How many chocolates were left with him?

Answers

Answer:

Karim had 130 chocolates left.

Step-by-step explanation:

The quick way to do this is to notice that if he gave away 35% of his chocolates, he must have 65% left. That comes about by doing

100% (which is what he started with) - 35% = 65%

65% of 200            Change 65% into a fraction

65/100 * 200          Multiply 200 * 65

13000 / 100            Divide by 100

130

Answer:

130 left

Step-by-step explanation:

35% of 200 chocolates is equal to 70 chocolates.

200-70=130 chocolates

r should be 4/7. You're comparing the given series to a geometric series that converges. By the limit comparison test, you have

What is an exponent?

The number of times a number has been multiplied by itself is referred to as an exponent. It could be an integer, a fraction, a negative integer, or a decimal. Powers or indices are other names for exponents. For instance, 6⁵ indicates that we are multiplying 6 by five. It is 6 × 6 × 6 × 6 × 6 in its expanded form.

How to solve this problem?

The expression is [tex]\sqrt[6]({g}^{5})[/tex].

[tex]\sqrt[6]{g}[/tex] can be written as [tex]g^{\frac{1}{6} }[/tex].

Then the given expression can be written as [tex]g^{\frac{5}{6} }[/tex].

Therefore, the expression equivalent to [tex]\sqrt[6]({g}^{5})[/tex], g > 0 is [tex]g^{\frac{5}{6} }[/tex]. So, option D is correct.

Suppose a normal distribution has a mean or 70 and a standard deviation of 7. What is P(x>=94)? O A. 0.075 O 8. 0.025 c. 0.84 OD 0,16​

Answers

Answer:

0.025

Step-by-step explanation:

Mean = 79 ; Standard deviation = 7

P(x ≥ 93)

We obtain the ZSCORE :

Zscore = (x - mean) / standard deviation

x = 93

Zscore = (93 - 79) / 7 = 2

P(Z ≥ 2) = 0.02275

Dan's car depreciates at a rate of 7% per year.
By what percentage has Dan's car depreciated after 6 years?
Give your answer to the nearest percent.

Answers

Answer:

20%

Step-by-step explanation:

Given that

The car is depreciated at a rate of 7% per year

We need to find out the percentage when the car is depreciated after 6 years

So,

Since the car is depreciated by 7% so we can say it can be 0.93 times in a year

Now after 6 years, it would make

= 0.93^3

= 0.80

So, the percentage is

= 1 - 0.80

= 0.20

= 20%

Answer:

Jada should use the tank of golf balls

Step-by-step explanation:

Jada should choose the tank that has a higher probability of choosing a ball with even number from.

Tank of tennis balls has two even numbers out of the ten balls (2, 4)

Tank of golf balls has seven even numbers out of the ten balls.

Tank of golf balls would give Jada more chance to pick an even number to win the game

Therefore, Jada should use the tank of golf balls

Given the statement “If a line is horizontal, then it has slope equal to zero,” what is its contrapositive?

Answers

Answer:

"If the line has a slope that is not 0, then the the line is not horizontal".

Step-by-step explanation:

The contrapositive of "If p then q" is "If not q then not p".

p=a line is horizontal

not p= a line that is not horizontal

q=the line has a slope equal to zero

not q=the line has a slope that is not zero

The equivalent statement in contrapositive form is therefore:

"If the line has a slope that is not 0, then the the line is not horizontal".

on the scale of a map 4 cm represent 20 km if the distance between two points is 10 cm what is the actual distance between this points​

Answers

Answer:

50 km

Step-by-step explanation:

Given

[tex]r = 4cm : 20km[/tex] -- Scale ratio

Required

Actual representation of 10cm

Let the actual measurement be x.

So, we have:

[tex]r =10cm:x[/tex]

Equate both value s of r

[tex]10cm : x = 4cm : 20km[/tex]

Express as fraction

[tex]\frac{x}{10cm } =\frac{20km}{4cm}[/tex]

Multiply by 10cm

[tex]10cm * \frac{x}{10cm } =\frac{20km}{4cm} *10cm[/tex]

[tex]x =\frac{20km}{4} *10[/tex]

[tex]x =5km *10[/tex]

[tex]x =50\ km[/tex]

Why or why not? sporting topics or comp.etition please help !!! 5 minutes !!! Pls help Ill brainlest Expand and simplify (3x+4)(2x+3) When writing goals, it is helpful to remember the acronym SMART. Different people associate different words with each of the letters in the SMART acronym, but for the purposes of this problem, SMART means that effective goals are: 1. Specific. A good goal defines exactly what you expect to accomplish. When your goals are specific, the behaviors required to accomplish them are clear. Many people say that they want to recycle to save the environment, but a better goal would be "Place every used bottle or can in a recycling container within five minutes of finishing its contents." 2. Measurable. You can measure the outcomes of a good goal. When you measure how much of a goal you have attained, you get feedback on your work. For example, compare the goal "I want to be skinny" with "I want to lose 10 pounds by the end of the month." How can you measure skinny? But by measuring the pounds you have lost so far, you know exactly how close you are to meeting your goal. 3. Attainable. Good goals are hard to reach, but not impossible. If a goal is too easy, you will not have to work hard to attain it, and your overall performance will not improve. If a goal is too hard, you will be discouraged from attempting to reach it. One way of making sure that goals are attainable is to break larger, difficult goals into smaller, more easily accomplished subgoals. 4. Result-oriented. A good goal contains only one outcome or accomplishment. If you combine two or more outcomes in one goal, it will be difficult to decide where to focus your attention. For example, "To increase produce sales by 3% and to achieve a 5% market share" is a less effective goal than "To increase produce sales by 3%." 5. Time-bound. Good goals specify precisely when you will meet them. Doing so provides you with a deadline for your actions. For example, it is easy to say "I want to be a millionaire." but you are more likely to accomplish that goal if you say "I will have a million dollars in a bank account by January 1, 2020." Using your knowledge of SMART goals, select the best goal. After the new product is released, I will hire some new salespeople. a.
