2: 335 cause you have to do 80b+5s= 80(4)= 320
5(3)=15
320+15=335

Determine the value of base b if (152)b = 0x6A. Please show all steps.

DaniilM [7]

Assuming 0x6A is given in base 16, first convert $152_b$ and $6A_{16}$ to a common base, say base 10:

$152_b=1\cdot b^2+5\cdot b^1+2\cdot b^0=(b^2+5b+2)_{10}$

$6A_{16}=6\cdot16^1+10\cdot16^0=106_{10}$

Then

$b^2+5b+2=106$

$b^2+5b-104=(b-13)(b+8)=0$

$\implies b=13$

What we know:

3.14 pi
radius: 7in.
Result units: in^3, this is the results of in used for radius; no conversion needed
Formula volume of a sphere: (4/3)* pi * r^3

(4/3)(3.14)(7)(7)(7)
(4/3)(3.14)(343)
(4/3)(1077.02)
(1.3)(1077.02) \\repeated 3 infinite
1436.026666\\repeated 6inf

The volume of the sphere is about 1436.0266 in^3

Sonya planted a flower garden of tulips, daisies and lilies. She planted 2 times as many tulips as daises and 3 tomes as many da

RideAnS [48]

70 flowers were planted in all.

Step-by-step explanation:

Let,

Tulips = t

Daises = d

Lilies = l

Total tulips planted = 42

She planted 2 times as many tulips as daises.

t=2d

Putting t=42

$42=2d\\2d=42$

Dividing both sides by 2

$\frac{2d}{2}=\frac{42}{2}\\d=21$

And 3 times as many daisies as lilies.

d=3l

Putting d=21

$21=3l\\3l=21$

Dividing both sides by 3

$\frac{3l}{3}=\frac{21}{3}\\l=7$

Total flowers planted = Tulips + Daisies + Lilies

Total flowers planted = 42 + 21 + 7 = 70

70 flowers were planted in all.

Find the height of a triangle with area = 110 ft squared and base = 10ft

maria [59]

Well to find the are of a triangle is like finding the are of a rectangle but in half so multiply 110 by 2 to get the original answer before it was divided by 2:

110×2=220

now we need to find out how many 10 are in 220:

220÷10=22

so the height of the triangle would be 22 ft

hope this helped
