Step-by-step explanation:

We know that the sum of all angles of a triangle is 180 °.

x + 45 + x + 64 + 79 ° = 180 °.

combine like terms

x + x + 64 + 45 + 79 ° = 180 °

2 x + 188 ° = 180 °

Subtract

2 x = 180 ° - 188 °

2 x = - 8 °

Divide

x = -8 ° / 2

x = - 4 °

x + 45 = - 4° + 45 ° = 41°

x + 64 = - 4° + 64 ° = 60 °

Answer:

Step-by-step explanation:

Sum of all angles of a triangle = 180

x + 64 + x + 45 + 79 = 180

Combine like terms.

2x + 188 = 180

2x = 180 - 188

2x = - 8

x = -8/2

x = -4

x + 64 = -4 + 64 = 60

x  + 45 = -4 + 45 = 41

The graph of f (0) = -4 cos 0 is shown below. The range of this function is
Anika [276]

Answer:

-4 ≤ f (\theta) ≤ 4

Step-by-step explanation:

The range of a function is the allowed y-values of the function.

We can simply look at the periodic function below and see that the y-value ranges from a negative 4 to a positive 4. It oscillates betwen -4 and 4. That is the range.

We can say -4 ≤ f (\theta) ≤ 4

Last answer choice is right.

*** <u>NOTE:</u> it is a type, not "0", rather "\theta"

A craft store buys 50 yards of satin ribon for $12.50. The store sells the ribbon by the foot. A customer can purchase 5 feet of
amm1812

Answer:

$8.1

Step-by-step explanation:

Convert 45 yards of ribbon to feet through proper conversion factor.  

  (45 yards)(3 ft / 1 yard) = 135 feet

Divide this number by 5 to determine the number of 5-ft ribbon that customers can purchased.

    n = 135 ft / 5 ft = 27

Then, multiply by $0.80.

   R = (27)($0.80) = $21.6

The profit is equal to $21.6 and $13.50,

    P = $21.6 - $13.50 = $8.1

Answer: $8.1

Identify the terms of the expression 9a+4b-18
madreJ [45]

Hey there!

We may ask. What exactly is a term anyways.

Well, a term is a single number, a variable, or a number and a variable that would have to be multiply together. This is what a term would be.

Therefore, as we look above, we see the following equation.

9a+4b-18

18 is a term

4b is a term

9a is a term

This whole thing, would be called an expression, as this is expression something. Perhaps the amount of students who ate ice-cream at a football game, or something similar.

I hope you found this helpful! :)

Which statement is correctly written as a conditional statement?
bekas [8.4K]

The statement that correctly written as a conditional statement is; A number, such as 10, is a composite number because it is even. so the correct option is D.

<h3>What are natural numbers, rational numbers, integers and irrational numbers?</h3>

Natural numbers are: 1, 2, 3, ....

Integer numbers are: ...., -2, -1, 0, 1, 2, ... (so it includes positive and negative natural number, and 0 )

Rational numbers are numbers which can be written in the form of a/b  

where a and b are integers.

Irrational numbers are those real numbers which are not rational numbers.

Here, Know that all natural numbers are integers, all integers are rational numbers. That means, natural numbers are not irrational.

A composite number is a number divisible by another number than 1 and the number itself.

To find example, a sum of two composite numbers, which is not a composite number, is needed.

The statement that correctly written as a conditional statement is; A number, such as 10, is a composite number because it is even.

Hence so the correct option is D.
