Answer:

0

4

15

27

Step-by-step explanation:

a) The first expression is

50-b^2+a

When a=2 and b=5, we get

50 -  {(5)}^{2}  + 2 = 50 - 25 + 2 = 27

b) The second expression is

a^2(5-b)

We substitute a=2 and b=5;

{2}^{2} (5 - 5) = 4(5 - 5) = 4 \times 0 = 0

c) The next expression is

{b}^{2}  - 10

We substitute b=5 to get:

{5}^{2}  - 10 = 25 - 10 = 15

d) The fourth expression is

a(b-3)

When a=2 and b=5

2(5 - 3) = 2 \times 2 = 4

We know that:

0<4<15<27

The degree measure of an acute angle in a right triangle is x. If sinx=2/3, determine if each of the following expressions is al
leonid [27]
<h2> ☞ANSWER☜ </h2>

The right triangle has one 90 degree angle and two acute (< 90 degree) angles. Since the sum of the angles of a triangle is always 180 degrees... The two sides of the triangle that are by the right angle are called the legs... and the side opposite of the right angle is called the hypotenuse.

An acute angle is an angle that measures less than 90 degrees. A triangle formed by all angles measuring less than 90˚ is also known as an acute triangle. For example, in an equilateral triangle, all three angles measure 60˚, making it an acute triangle.

Sam has fewer baseball cards than Jill (she has 36). There are only three ways that he can arrange all of his cards in equal row
pantera1 [17]

Answer:

27, 30, 33

Step-by-step explanation:

Since Sam has fewer number of baseball cards than Jill who has 36 baseball cards and can arrange all his cards in only three ways, the possible number of baseball cards that Sam could have is 27, 30 or 33.

If he has 27 baseball cards, he can arrange 9 baseball cards per row in 3 rows

If he has 30 baseball cards, he can arrange 10 baseball cards per row in 3 rows

If he has 33 baseball cards, he can arrange 11 baseball cards per row in 3 rows
