Answer:

$50$

Step-by-step explanation:

Follow the PEMDAS order of operations:

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction.

Calculate the Parentheses- (12-8)

This will equal 4.

$36+4+2x5$

(x= times)

Multiply and divide, left to right.

$2x5=10$

$36+4+10=50$

Answer:

Step-by-step explanation:

To answer this we need to use the PEMDAS strategy, first solve any questions in parentheses, next solve all multiplication and division problems from left to right. Next, solve all addition and subtraction problems from left to right.

36 + (12 - 8) + 2 × 5

36 + 4 + 2 x 5

36 + 4 + 10

40 + 10

The hypotenuse of a 45 degrees -45 degrees -90 degrees triangle measures 10 root of 5 in.

juin [17]

Answer:

$5\sqrt{10}\ in$

Step-by-step explanation:

The question is

Find the measure of the legs

we know that

In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal

Let

a ----> the measure of one leg

Applying the Pythagorean Theorem

$(10\sqrt{5})^2=a^2+a^2$

solve for a

$500=2a^2$

Divide by 2 both sides

$a^2=250$

$a=\sqrt{250}\ in$

Simplify

$a=5\sqrt{10}\ in$

In a quadratic function you square x so I'd assume that's what they want.

That means the values of f(x) would be:

We can calculate eee, the amount of euros that has the same value as ddd u.S. Dollars, using the equation e=\dfrac{17}{20}de= 20

Cloud [144]

We are given eqaution: $e=\frac{17}{20}d$ , where e the amount of euros and d is the value as U.S. Dollars.

We need to find number of euros for 1 U.S. Dollar.

Plugging d=1 in the given equation

We get

$e=\frac{17}{20}(1)$

On simplfying , we get

$e=\frac{17}{20}$

Dividing 17 by 20, we get 0.85.

Therefore, there would be 0.85 euro have the same value as 1 U.S. Dollar.

Which statements are true for solving the equation 0.5 – |x – 12| = –0.25? Check all that apply.

Trava [24]

we have

$0.5-\left|x-12\right|=-0.25$

we know that

The absolute value has two solutions

Subtract $0.5$ both sides

$-\left|x-12\right|=-0.25-0.5$

$-\left|x-12\right|=-0.75$

Step 1

Find the first solution (Case positive)

$-[+(x-12)]=-0.75$

$-x+12=-0.75$

Subtract $12$ both sides

$-x+12-12=-0.75-12$

$-x=-12.75$

Multiply by $-1$ both sides

$x=12.75$

Step 2

Find the second solution (Case negative)

$-[-(x-12)]=-0.75$

$x-12=-0.75$

Adds $12$ both sides

$x=-0.75+12$

$x=11.25$

Statements

case A) The equation will have no solutions

The statement is False

Because the equation has two solutions------> See the procedure

case B) A good first step for solving the equation is to subtract 0.5 from both sides of the equation

The statement is True -----> See the procedure

case C) A good first step for solving the equation is to split it into a positive case and a negative case

The statement is False -----> See the procedure

case D) The positive case of this equation is 0.5 – |x – 12| = 0.25

The statement is False

Because the positive case is $0.5-(x-12)=-0.25$ -----> see the procedure

case E) The negative case of this equation is x – 12 = –0.75

The statement is True -----> see the procedure

case F) The equation will have only 1 solution

The statement is False

Because The equation has two solutions------> See the procedure

If you are asked to find 621 / 59 how do you know the quotient will be greater than 10 before you actually divide?

vova2212 [387]

You will know that it is greater than 10 because it goes into 621 more than 10 times
