Answer:

d =1.501060821 in

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The volume is 1.77 in^3

1.77 = 4/3 (3.14) r^3

1.77 = 4.1866666 r^3

Divide each side by 4.18666666

1.77/4.18666666 = r^3

.422770701 = r^3

Take the cube root of each side

(.422770701)^(1/3) = (r^3)^1/3

.75053041 = r

But we want to find the diameter. The diameter is twice the radius.

d= 2r

d = 2(.75053041)

d =1.501060821 in

Learning task 1: find the value of the expression given the value of the variables 3x + 5 x = 2 5xy + x - 4 , x = -3 and y = 5

olasank [31]

Step-by-step explanation:

3x+5x=25xy+x-4

8x=25xy+x-4

8(-3)=25(-3)(5)+(-3-4)

-24=25(-15)+(-7)

-24= -375-7

-24= -382

if the question is right that you asked, i mean the = sign then the solution is will be come like this but if there is no = sign then you can get the solution by subtracting -24-382= -406

Can you form a right triangle with the three lengths given? Why or why not? 5 cm, 12 cm, 13 cm

nordsb [41]

Yes, I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.

<h3>What is a right-angled triangle?</h3>

A right-angled triangle serves as the triangle having one of its angles equal to 90 degrees.

It should be noted that the other two angles sum up to 90 degrees., hence I form a right triangle with the three lengths given, because The largest side which is 13cm can be squared and will be set to equal to the sum of squares of smaller two side.
