Answer:

The answer is False.

Step-by-step explanation:

Given a quadrilateral ABCD with angles ∠A=90°, ∠B=90°, ∠C=115° and ∠D=65°

We have to tell about the statement true or false

'A circle could be circumscribed about the quadrilateral'

As, we say a circle can be circumscribed about the quadrilateral if and only if the quadrilateral is cyclic and also if the opposite angles of a quadrilateral are supplementary, then only the quadrilateral is cyclic.

Hence, we have to check for the opposite angles of quadrilateral if they are supplementary then we say the above statement is true i.e A circle could be circumscribed about the quadrilateral.

∠A+∠C=90+115=205° ≠ 180°

⇒ opposite angles are not supplementary.

∴ A circle could not be circumscribed about the quadrilateral.

The above statement is false.

The grocery store where Ms. Maple works pays her $6.50 per hour. Any time she works more than 40 hours per week, she is paid tim

Charra [1.4K]

Answer:

$289.25

Step-by-step explanation:

First we should find out how much Ms. Maple would make in a week without overtime.

6.5 x 40 = 260

Now, let's figure out how much she makes per hour in overtime.

6.5 x 1.5 = 9.75

Now add up the hours of overtime.

9.75 x 3 = 29.25

Now we add the weekly wage to the overtime

260 + 29.25 = 289.25

For 40 hours of regular time at $6.50/hr and 3 hours of overtime at $9.75/hr, Ms. Maple will make $289.25 for the week.

Solve the inequality |* +31 < |2x + 1.<br> |x+3|<|2x+1|

Kisachek [45]

Answer:

Step-by-step explanation:

Here are the steps to follow when solving absolute value inequalities:

Isolate the absolute value expression on the left side of the inequality.

If the number on the other side of the inequality sign is negative, your equation either has no solution or all real numbers as solutions.

If your problem has a greater than sign (your problem now says that an absolute value is greater than a number), then set up an "or" compound inequality that looks like this:

(quantity inside absolute value) < -(number on other side)

(quantity inside absolute value) > (number on other side)

The same setup is used for a ³ sign.

If your absolute value is less than a number, then set up a three-part compound inequality that looks like this:

-(number on other side) < (quantity inside absolute value) < (number on other side)

The same setup is used for a £ sign
