Answer: So the answer is 36

Step-by-step explanation:

<h2><u><em>In order to find the next time Kendra will have both tests on the same day, find the least common multiple of each increment of days. </em></u></h2><h2><u><em> </em></u></h2><h2><u><em>Write some multiples of each number, and then find the smallest multiple that both numbers have in common. </em></u></h2><h2><u><em> </em></u></h2><h2><u><em> </em></u></h2><h2><u><em> </em></u></h2><h2><u><em>The smallest multiple that both numbers have in common is 36. </em></u></h2><h2><u><em> </em></u></h2><h2><u><em>Therefore, Kendra will have both tests on the same day again in 36 school days. </em></u></h2><h2><u><em> </em></u></h2>

Round the numbers to the nearest cent and then to the nearest dollar. 23. $62.756 24. $38.415
MrMuchimi

Answer:

23.  $ 62.76  to the nearest cent

      $63.00 to the nearest dollar

24.  $ 38.42  to the nearest cent

      $38.00 to the nearest dollar

Step-by-step explanation:

When we round to the nearest cent we round the second number after the decimal.  We look at the third number after the decimal.  If it is 5 or above we round up.

When we round to the nearest dollar, we round the number befroe the decimal. We look at the number after the decimal.  If it is 5 or above we round up.

23.  $62.756  we round the 5 so we look at the 6   6>= 5  so we round up

         $ 62.76  to the nearest cent

    $62.756  we round the 2 so we look at the 7  7>= 5  so we round up

          $63.00 to the nearest dollar

24. $38.415 we round the 1 so we look at the 5   5>= 5  so we round up

         $ 38.42  to the nearest cent

    $38.415  we round the 8 so we look at the 4  4< 5  so we leave alone

          $38.00 to the nearest dollar

Given ƒ(x) = 2x2 − 3x + 7, find ƒ(2.5)
dsp73
Assuming 2x2 is 2x^{2} &#10; you would get 2(2.5)(2.5) - 3(2.5) +7, which is 2(6.25) - 7.5 + 7, 12.5 - 0.5, [12]

maksim [4K]
When you multiply powers, you add them. You keep the constant (2) the same.

3+18= 21

2^21 <=== the answer

“D” is the answer.

I hope this helps!

David found and factored out the GCF of the polynomial 80b4 – 32b2c3 + 48b4c. His work is below.
Vikentia [17]

Answer:

Given Polynomial:

80b^4-32b^2c^3+48b^4c

Factors of Coefficient of terms

80 = 5 × 16

32 = 2 × 16

48 = 3 × 16

Common factor of the coefficient of all term is 16.

Each term contain variable. So the Minimum power of b is common from all terms.

Common from all variable part comes b².

So, Common factor of the polynomial = 16b²

⇒ 16b² ( 5b² ) - 16b² ( 2c³ ) + 16b² ( 3b²c )

⇒ 16b² ( 5b² - 2c³ + 3b²c )

Therefore, Statements that are true about David's word are:

The GCF of the coefficients is correct.

The variable c is not common to all terms, so a power of c should not have been factored out.

In step 6, David applied the distributive property
