Answer:

Step-by-step explanation:

Compare the ratios of the triangles like so:

Bigger to smaller

$\frac{15}{10}=\frac{12}{8}$

This statement is true. Both fractions simplified are equal to 1.5. Since they have the same ratios, they should be similar.

If (x, -3) is on the line described by f(x)=-x+8, what is the value of x

qwelly [4]

The value of <u>x</u> that the given point of the function is 11.

<h3>Linear Function</h3>

An equation can be represented by a linear function. The standard form for the linear equation is: y= ax+b , for example, y=5x+3. Where:

a= the slope

b= the constant term that represents the y-intercept.

For the previous example: a=5 and b=3.

The question gives a point (x , -3) of a function f(x)= -x+8. Therefore, you can write

-3=-x+8

x=8+3

x=11

Thus, the x-coordinate is equal to 11.

If tile costs $8.50 per square foot, how much does it cost per inch?

Sphinxa [80]

Answer:

$0.06 per square inch

Step-by-step explanation:

The question should be:

<em>"If tile costs $8.50 per square foot, how much does it cost per square inch?"</em>

<em />

To solve this, we basically need a conversion from feet to inches. BUT 2 times, since we are talking about "square feet" and "square inches".

We know 1 feet = 12 inches

Also, since we are going from square feet to square inches [big to small], we have to divide TWICE.

Thus, we will have:

$\frac{8.5}{12*12}$

We are dividing 8.5 (the cost) by 12, 2 times since we want square feet in square inches. The answer is:

$\frac{8.5}{12*12}=0.06$

So, tile costs $0.06 per square inch

Angle 0 lies in the second quadrant and sin 0 = 3/5 cos= coy =

Elza [17]

Consider the right triangle ABC with legs AB=4, AC=3 and hypotenuse BC=5. Angle B has
$\sin B=\frac{opposite}{hypotenuse} = \frac{3}{5}$ and
$\cos B = \frac{adjacent}{hypotenuse} = \frac{4}{5}$ .

Since O lies in second quadrant $\cos O\ \textless \ 0$ and
$\cos O= -\cos B =- \frac{4}{5}$ .
Answer: $\cos O=- \frac{4}{5}$ .
