How to multiply to the nearest ten

1 answer:

4 0

I'm not sure what you mean by this, but if you mean rounding, I got an answer.

Say you're rounding 24 to 30.
24 is closer to 20 than 30.

But if you were rounding 25 to 30, 25 would be closer to 30, not 20.
I guess it's kind of confusing.

Simplify x0 y-3/x2 y-1

Natali5045456 [20]

Answer:

x^0 y^-3 / x^2 y^-1

= 1 / x^2 y^-1 (y^3) ...because x^0 = 1 and [(y^-1) (y^3)] = y^2

= 1/(x^2 y^2)

A certain building has a triangular shaped face to link up of the sides of the triangular base or 145 feet 257 feet in 290 feet

attashe74 [19]

Answer:

18617.66 ft^2

Step-by-step explanation:

sides of triangular base

a= 145ft ,

b = 257ft ,

c = 290ft

<u>calculate the area of the base </u>

The base is a scalene triangle hence the area is calculated as follows

s = ( a + b + c ) / 2

= ( 145 + 257 + 290 ) / 2 = 346

Area of triangle = $\sqrt{s(s-a)(s-b)(s-c)} = \sqrt{346(201)(89)(56)}$

= 18617.66 ft^2

Write the equation of a line, in slope-intercept form, that has a slope of m=9 and passes through the point (4, 31)

Darina [25.2K]

Answer:

9x-y = 5

Step-by-step explanation:

Equation of line in slope intercept form:

y-y1 = m*(x-x1), m=9, (x1,y1)=(4,31)

y-31 = 9*(x-4)

y-31 = 9x-36

9x-y = 36-31

9x-y = 5

Ryan's tennis club membership, which is $11, is deducted automatically from his bank account every month. Which expression shows

Solnce55 [7]

(-$11) x 12. That would be the equation because there are 12 months, so you would multiply -11 from 12 to get -132 every year for the tennis club membership.
