Let’s put this into a proportion.

4/40=x/50

Remember it says solve using unit rates so we can simplify 4/40 to 1/10

1/10=x/50

Now we can cross multiply.

10·x = 1·50

10x=50

X=5

Hope that helped!

Your friend claims that it is possible to draw a right triangle where the cosine of either angle (theta) is exactly the same val

avanturin [10]

Answer:

B. No

$Cos \ \theta\neq Cos (90-\theta)\textdegree$

Step-by-step explanation:

-A right angle triangle has two complimentary acute angles and one right angle.

- $\theta$ is usually one of the acute angles and is equivalent to 90º minus it's complimentary acute angle.

-Complimentary angles add up to 90º.

#For complimentary angles:

$Sin \ \theta=Cos \ (90-\theta)\textdegree\\\\Cos \ \theta=Sin(90-\theta)\textdegree\\\\\therefore Cos \ \theta\neq Cos (90-\theta)\textdegree$

The two acute angles cannot have the same Cosine value.

Hence, she's not correct.

Simplify 1/4(8x+16)+4x.

QveST [7]

Answer:

6x+4

Step-by-step explanation:

First thing to do is distribute 1/4 into the parenthesis. So 1/4 times 8x and 16. Which will give you 2x and 4. Then add like terms which will be 2x + 4x which is 6x. Then you have the 4 left over so your new equation is 6x+4.

at a clothing store, levi's jeans are on sale for 40% off. sales tax is 7%. which expression will calculate the total cost of le

aleksandrvk [35]

Given:

Discount = 40%

Sales tax = 7%

To find:

The total cost of levi jeans with an original price of x.

Solution:

Let x be the original price of the jeans. Then the price after 40% discount is

$Price=x-40\%\text{ of }x$

$Price=x-\dfrac{40}{100}x$

$Price=x-0.4x$

$Price=0.6x$

The price after 7% of sales tax.

$Price=0.6x+7\%\text{ of }0.6x$

$Price=0.6x+\dfrac{7}{100}\times 0.6x$

$Price=0.6x+0.042x$

$Price=0.642x$

Therefore, the total cost of the levi jeans with an original price of x is represented by the expression 0.642x.
