Answer:

12 < x

Step-by-step explanation:

In writing 12 less than a number x, the expression, 12 - x is wrong because "less than" is not the same thing as "minus" (-). Rather, the sign, "<" should have been used as follows:

12 < x.

Complete Question

Because triangle XYZ is a right triangle, the side lengths must satisfy the Pythagorean theorem, a² + b² = c², which in this isosceles triangle becomes a² + a² = c². By combining like terms, 2a² = c². Which final step will prove that the length of the hypotenuse, c, is StartRoot 2 EndRoot times the length of each leg?

a) substitute values for a and c into the original pythagorean theorem equation.

b) divide both sides of the equation by two, then determine the principal square root of both sides of the equation.

c) determine the principal square root of both sides of the equation.

d) divide both sides of the equation by 2.

Answer:

c) determine the principal square root of both sides of the equation.

Step-by-step explanation:

Pythagoras Theorem for a right angled triangles states that:

a²+ b²= c²

But for an Isosceles Triangle, where two sides of the triangle are equal, we have:

a²+ a² = c²

By combining like terms

2a² = c²

We square root both sides of the equation.

√2a² = √c

√2a² = c

The final step will prove that the length of the hypotenuse, c, is StartRoot 2 EndRoot times the length of each leg = √2a² = c is Option c.

wrangler has 300 dollars to spend on school supplies. He spent 1/10 on notebooks. How much does he have left?
marshall27 [118]

Answer:

Step-by-step explanation:

<u>Method 1:</u>

$300 on school supplies

1/10 on notebooks

As you're finding how much is left:

10/10-1/10=9/10

Convert 9/10 into a decimal

9/10=0.9

300*0.9=$270

OR

<u>Method 2: </u>

1/10=0.1

300*0.1=$30

Take away 30 from $300

$300-30=$270

By using either method, You would still have $270 left.

How this helps!!!

Have a nice day :)

Which correctly describes how the graph of the inequality −4y − x ≥ 7 is shaded?
harkovskaia [24]

Answer: Below the solid line

Step-by-step explanation:

-4y - x ≥ 7

add x to both sides

-4y ≥ x + 7

divide by -4 on both sides

y ≤ -1/4x - 7/4 = (1.75)

Take the origin (0,0) and substitute it for the variables

y(0) ≤ -1/4(0) - 7/4

0 ≤ -7/4 = (1.75)

This statement is false, so you would shade on a graph, below the solid line, since this is where the origin would not be.

The line would be solid because the < is underlined.

Bcc Medical Radiography program had 139 graduates. There were 25 more females than males. How many females and males graduated?
NISA [10]
F=m+25

m+f=139, using f from above we have:

m+(m+25)=139

2m+25=139

2m=114

m=57, and since f=m+25

f=82

So there are 57 males and 82 females.
