Answer:

Therefore, Sara’s current age (5 years later) is 19 years old.

Step-by-step explanation:

Let xx be Sara’s age five years ago. Therefore, Sara’s aunt’s age 5 years ago is 4x4x.

The difference in their ages is a constant, no matter how many years have gone by. (Can you see why?)

4x−x=42

3x=42

x=42/3

x=14

14+5=19

Therefore, Sara’s current age (5 years later) is 19 years old.

the unit digitsof a two numberis 1 less than twice the ten digit. if the sum of tje digits is 9, find the number.
Amiraneli [1.4K]
Are you sure this is written correctly? Any number whose digits add to 9 is divisible by 9.  For a 2 digit number then, your choices are
18, 27, 36, 45, 54, 63, 72, and 81.  None of these has the property that for the 2 digit number AB that B=2A-1.  Solving your question algebraically is possible but you get fractional digits.

Answer the following questions about the sphere whose equation is given by x2+y2+z2−8x+4y=−4. 1. Find the radius of the sphere.
Anna [14]

Answer:

we have (a,b,c)=(4,-2,0) and R=4 (radius)

Step-by-step explanation:

since

x²+y²+z²−8x+4y=−4

we have to complete the squares to finish with a equation of the form

(x-a)²+(y-b)²+(z-c)²=R²

that is the equation of a sphere of radius R and centre in (a,b,c)

thus

x²+y²+z²−8x+4y=−4

x²+y²+z²−8x+4y +4 = 0

x²+y²+z²−8x+4y +4 +16-16 =0

(x²−8x + 16) + (y² + 4y + 4 ) + (z²) -16 = 0

(x-4)² + (y+2)² + z² = 16

(x-4)² + (y-(-2))² + (z-0)² = 4²

thus we have a=4 , b= -2 , c= 0 and R=4

An Native American tepee is a conical tent. Find the number of cubic feet of air in a teepee 10 ft. in diameter and 12 ft. high.
marta [7]
For this case what you should know is that by definition the volume of the cone is given by:
 V = ((pi) * (r ^ 2) * (h)) / (3)
 Remembering that:
 r = d / 2
 Substituting the values:
 V = ((pi) * ((d / 2) ^ 2) * (h)) / (3)
 V = ((pi) * (((10) / 2) ^ 2) * (12)) / (3)
 V = 314.16 ft ^ 3
 Answer:
 V = 314.16 ft ^ 3
 The nearest option is:
 300 cu. ft
