Karen received $ 213 for 10 days of serving

<em><u>Solution:</u></em>

Given that When karen serves jury duty, she will receive $15 each day for the first three days she serve

To find: money received by karen if she served for 10 days

First three days = $ 15 each day

Therefore,

first day = $ 15

second day = $ 15

third day = $ 15

After three days, she will receive $24 each day she serves

4th , 5th, 6th, 7th , 8th , 9th, 10th day = $ 24 each day

If she serves for 10 days,

money received = 15 + 15 + 15 + 24 + 24 + 24 + 24 + 24 + 24 + 24

money received = 3(15) + 7(24)

money received = 45 + 168 = 213

Thus karen received $ 213 for 10 days of serving

Answer:

213

Step-by-step explanation:

So the answer 213 because

3 days is $15 so that 45

since they say 10 days take 3 days for 10 and it 7 so 7 x 24 is 168

45+ 168= 213

S the following statement always, sometimes, or never true?
liubo4ka [24]

The statement <em>“The supplement of an acute angle is an obtuse angle.”</em> is always true because the sum of any two supplementary angles is 180°, so if one of them less than 90° (acute), then the other must be greater than 90° (obtuse)

Step-by-step explanation:

Let us revise some facts about the supplementary angles

  • Supplementary angles are two angles the sum of their measure is 180°
  • The two angles could be right angles or one of them is acute and the other is obtuse
  • The two angles can not be acute angles or obtuse angles

Let us take some examples to explain the facts above

∵ One of two supplementary angles is a right angle

∵ The measure of the right angle is 90°

∵ The sum of the measures of the supplementary angles is 180°

∴ 90 + the measure of the supplement angle = 180

- Subtract 90 from both sides

∴ The measure of the supplement angle = 90°

∴ The supplement of a right angle <u><em>must be</em></u> a right angle

∵ One of two supplementary angles is 70°

∵ Its measure less than 90°

∴ This angle is an acute angle

∵ The sum of the measures of the supplementary angles is 180°

∴ 70 + the measure of the supplement angle = 180

- Subtract 70 from both sides

∴ The measure of the supplement angle = 110°

∵ Its measure greater than 90°

∴ The supplement angle is an obtuse angle

∴ The supplement of an acute angle <u><em>must be</em></u> an obtuse angle

The two supplementary angles can not be acute angles because their sum is less than 180°

The two supplementary angles can not be obtuse angles because their sum is greater than 180°

The statement <em>“The supplement of an acute angle is an obtuse angle.”</em> is always true because the sum of any two supplementary angles is 180°, so if one of them less than 90° (acute), then the other must be greater than 90° (obtuse)

State the value of the discriminant of -6x^2 +2x + 3 = 0
Dmitry [639]

Answer:

76

Step-by-step explanation:

recall that for a quadratic equation in the form

ax² + bx + c = 0, the discriminant is given by

discriminant, D = b²- 4ac

we are given the following:

-6x² + 2x + 3 = 0,

comparing this with the general equation above, it is clear that,

a = -6, b = 2 and c = 3,

substituting these into our equation for discriminant:

D = b²- 4ac

= 2² - 4(-6)(3)

= 4 + 72

= 76
