Answer:

5>t

Step-by-step explanation:

45 > 12t + 3(t -8) - 6 multiply 3 times t-8

1) 45 > 12t + 3t - 2 - 6 combine alike terms

2) 45 >  15t - 30 isolate the variable by adding 30

3) 75 > 15t divide by 15

4) 5 > t

Answer:

128

Step-by-step explanation:

512/4

Answer:

a = 8 cm, as cube root of 512 is 8. The side lengths (edges) are 8 cm.

Step-by-step explantation

8 cubic feet = 2 feet 512 cubic feet.

First you  Multiply your length, width and height figures together, giving you a total in cubic inches (in3)Divide the total by 512 (as there are 512 cubic inches in a cubic foot) it equals to 8 meaning your answer is correct. I f not it wrong and I already look this this up its 8

Answer:

[tex]\boxed{\text{Center at } (7, -4), \text{ Radius of } 7.}[/tex]

[tex]\text{Formula for a circle: } (x - h)^{2} + (y - k)^{2} = r^{2} \text{ Where:}[/tex]

[tex]h = \text{ x-coordinate of center}\\\\k = \text{ y-coordinate of center}\\\\r = \text{ radius}\\\\\text{Therefore:}[/tex]

[tex]\text{In the equation } (x - 7)^{2} + (y + 4)^{2} = 49:[/tex]

[tex]h = 7\\\\k = -4\\\\r = \sqrt[]{49} = 7 \\\\\text{So:}[/tex]

[tex]\text{Center at } (7, -4), \text{ Radius of } 7.[/tex]

Answer:

Center = (7, -4)

Radius = 7

Step-by-step explanation:

The general equation of a circle is:

[tex](x-h)^{2}+(y-k)^{2}=r^{2}[/tex]

where (h, k) is the center of the circle and r is the radius.

The equation given is in the form of the general equation of a circle. Knowing this, we will be able to find the center and radius by finding h, k, and r.

[tex](x-7)^{2}+(y+4)^{2}=49[/tex]

We can turn the 49 into 7² (√49 = 7, so 49 = 7²) and turn the equation into:

[tex](x-7)^{2}+(y+4)^{2}=7^{2}[/tex]

Now we can see that:

h = 7

k = -4

r = 7

So the center of the circle would be (7, -4) and the radius would be 7.

I hope you find my answer helpful.

Answer:

probability of tossing a coin 3 times and getting heads each time is 1/8

Step-by-step explanation:

A coin has 2 sides (heads and tails) therefore you have a 50% chance of getting either heads or tails for each toss. Therefore, the probability of getting heads for 1 toss is 1/2. Now, tossing it 3 times and getting heads each time essentially means you would have to do (1/2)×(1/2)×(1/2) which would give you 1/8 as the probability of tossing a coin 3 times and getting heads each time.

Answer:

[tex]x^3+x^2-2x\leq140[/tex]

Step-by-step explanation:

This is an algebra problem, and we are expected to inequality for the volume of the aquarium.

Given that the

length= 2x

width=(x – 1)

heigth=  (x + 2)

and the volume= 280 ft^3

the inequality expression for the volume is

[tex]2x*(x -1) * (x + 2) \leq 280\\\\[/tex]

open the brackets

[tex]2x*(x -1) * (x + 2) \leq 280\\\\(2x^2-2x)*(x+2)\leq 280\\\\\2x^3+4x^2-2x^2-4x\leq 280\\\\\2x^3+2x^2-4x\leq280[/tex]

divide through by 2 we have

[tex]x^3+x^2-2x\leq140[/tex]

Answer:

The distance between the points (6,-4) and (0,5) = 10.82 units

Step-by-step explanation:

Distance formula

Length of a line segment with end points (x1, y1) and (x2, y2) is given by,

Distance = √[(x2 - x1)² + (y2 - y1)²]

To find the distance between given points

Here, (x1, y1)  =  (6, -4) and (x2, y2)  = (0, 5)

Distance = √[(x2 - x1)² + (y2 - y1)²]

= √[(0 - 6)² + (5 - -4)²]

=√[(-6)² + (9)²]

= √[36 + 81]

= √[117

= 10.82

The distance between the points (6,-4) and (0,5) = 10.82 units

Answer:

Step-by-step explanation:

2x + 3.5x + 15 = -1.5

5.5x + 15 = -1.5

5.5x = -16.5

x = -3

y = 3.5(-3) + 15

   = -10.5 + 15

    = 4.5

Answer:

the answer would have to be: 19894.05

Answer:

Step-by-step explanation:

Q4 NO 1

x-5+3x+x+65= 180 degrees

x+3x+x+65-5= 180 degrees

5x+60= 180 degrees

5x=180-60

5x= 120

Divide both sides by 5

x=24

Q4 NO 2

5y-20+y+200= 360 degrees

5y+y+200+20= 360 degrees

6y+220= 360 degrees

6y= 360-220

6y=180 degrees

Divide both sides by 6

y= 30 degrees
