<span>Given that Tamara's annual salary is $48,000 means that his monthly salary is $48,000 / 12 = $4,000. For Tamara to make $6,000 this month, she needs to make an additional $2,000 from commissions in addition to her salary. Given that she earns 4% commision on all sales, let the sale she needs to make to get $2,000 be S, then 4 / 100 x S = 2000 this gives 0.04S = 2000 giving that S = 2000 / 0.04 = 50,000. Therefore, Tamara needs to make a sales of $50,000 to be able to earn $6,000 this month.</span>
Answer:
Radius = 8.575 cm
Step-by-step explanation:
Formula for volume of a pyramid is;
V_p = ½Ah
Where A is area of base and h is height
Also, formula for volume of cone is given as;
V_c = ⅓πr²h
Now, we are told that V_p = V_c and that h is the same for both shapes.
Thus ;
½Ah = ⅓πr²h
h will cancel out to give;
½A = ⅓πr²
Cross multiply to give;
3A/2π = r²
Base area of pyramid is given as 154 cm². Thus;
(3 × 154)/2π = r²
r = √((3 × 154)/2π
r = 8.575 cm
Answer:
THE ANSWER IS B
Step-by-step explanation:
NO EXPLANATION JUST TRUST ME
<span>1. </span>The
volume is comprise of a cube and prism
V = ( x + 2) ( 2x + 4) + ( x + 2)^2
Solve for x
X = 10.12
<span>2. </span>1050
= (2x – 4) ( 3x) 5
1050 = (2x – 4) 15x
1050 = 30x^2 – 60x
Solve for x
X = 7
<span>3. </span>148 = ( x – 5) ( x – 6 ) ( x – 4)
Solve for x
X = 10.35
<span>4. </span>144pi
= pix^2(21)
X = 2.62
