3^(3)•4-(48-3)/5^(2)-18

Mathematics
1 answer:
gizmo_the_mogwai [7]3 years ago
4 0

Answer:

9

Step-by-step explanation:

  1. Do the brackets first (48-3=45). You now have 3^3 X. 4 - 45 / 5^2 - 18
  2. Do the powers next 3^3 = 27. 5^2 = 25
  3. Now you have 27 X 4 - 45 / 25 - 18
  4. Do 27 X 4, = 108.
  5. Now you have 108 - 45 / 25 - 18
  6. 108 - 45 = 63
  7. 25 - 18 = 7
  8. 63/7 = 9

2 u + 12 &lt; 23<br> 0,1 d + 8 &gt; 0<br> 3 - 4 r &gt; 7<br> 13 &lt; 2 z + 3<br> 6 ≥ 9 - 0, 15 i
BartSMP [9]

Answer:

Part 1) u< 5.5  

Part 2) d > -80

Part 3) r < -1

Part 4) z>5

Part 5) i\geq 20

Step-by-step explanation:

<u><em>The question is</em></u>

Solve each inequality for the indicated variable

Part 1) we have

2u+12

subtract 12 both sides

2u< 23-12\\2u

Divide by 2 both sides

u< 5.5

The solution is the interval (-∞,5.5)

In a number line the solution is the shaded area at left of u=5.5 (open circle)

The number 5.5 is not included in the solution

Part 2) we have

0.1d+8 >0

subtract 8 both sides

0.1d > -8

Divide by 0.1 both sides

d > -80

The solution is the interval (-80,∞)

In a number line the solution is the shaded area at right of d=-80 (open circle)

The number -80 is not included in the solution

Part 3) we have

3-4r> 7

Subtract 3 both sides

-4r>7-3\\-4r>4

Divide by -4 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

r < -1

The solution is the interval (-∞,-1)

In a number line the solution is the shaded area at left of r=-1.1 (open circle)

The number -1.1 is not included in the solution

Part 4) we have

13< 2z+3

Subtract 3 both sides

13-3

Divide by 2 both sides

5

Rewrite

z>5

The solution is the interval (5,∞)

In a number line the solution is the shaded area at right of z=5 (open circle)

The number 5 is not included in the solution

Part 5) we have

6\geq 9-0.15i

Subtract 9 both sides

6-9\geq -0.15i\\-3\geq -0.15i

Divide by -0.15 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

20\leq i

Rewrite

i\geq 20

The solution is the interval [20,∞)

In a number line the solution is the shaded area at right of i=20 (closed circle)

The number 20 is included in the solution

if a quadratic equation with real coefficients has a discriminant of -36 then what type of roots does it have
Aleks04 [339]

Step-by-step explanation:

We have,

If a quadratic equation with real coefficients has a discriminant of -36.

The general form of quadratic equation is :

ax^2+bx+c=0

The discriminant of this equation is : D=b^2-4ac

If D=0, it will have 1 real roots

If D>0, it will have 2 real roots

If D<0, it will have no real roots

We have,

D = -36 < 0, so, the quadratic equation will have no real roots.

The two triangles below are similar. What value of Q and B would make this true
Alenkinab [10]

Answer:

  • ∠B = ∠Q = 26°

Step-by-step explanation:

<u>The angles B and Q should be same, therefore:</u>

  • Q = 4x + 2 and B = 15x - 64

<u>The equation below as per above, solving for x:</u>

  • 4x + 2 = 15x - 64
  • 15x - 4x = 64 +2
  • 11x = 66
  • x = 6

<u>Then the angle measures:</u>

  • 4*6 + 2 = 26°
