Answer:
Step-by-step explanation:
y = -2x + 5
x = -4 ; y = -2*-4 +5 = 8+5 = 13
x = -3; y = -2*-3 + 5 = 6+5 =11
x = -2; y = -2*-2 + 5 = 4+5 = 9
x= -1; y = -2*-1 + 5 = 2+5 = 7
x = 0; y= -2*0 + 5 = 0+5 = 5
x= 1; y = -2*1 + 5 = -2 +5 = 3
x= 2; y = -2*2 + 5 = -4+5 =1
x=3; y= -2*3 + 5 = -6+5 = -1
x = 4; y = -2*4 + 5= -8 + 5 = -3
8 out of 12 people were happy.
8/12 reduces to 2/3 of the people were happy.
Multiply the total people surveyed by 2/3:
126 x 2/3 = (126 x 2) /3 = 252/3 = 84
84 people were happy.
Let
x-----------> <span>the side length of a pyramid square base
h-----------> t</span>he height of the sculpture <span>in the shape of a pyramid
we know that
h=(x-3)
Volume=162 cm</span>³
Volume=x² *(x-3)/3
then
x² *(x-3)/3=162----------> x³-3x²=486----------> x³-3x²-486=0
x³-3x²-486=0-------- <span>this equation can be used to find the length of the sculpture’s base
using a graph tool-----------> </span>to find the solution
x=9 cm -------------> see the attached figure
h=(x-3)-----> h=9-3--------> h=6 cm
the answer is
<span>
the length of the sculpture’s base is 9 cm</span>
the height of the sculpture is 6 cm
Answer:
3,2,6
Step-by-step explanation:
if you divide 10,398 by all numbers 3,2 and 6 have whole numbers:)
Ni is not correct. To solve
the equivalent quarterly interest rate, the annual interest rate should be multiplied
by the correct ratio. Since the annual interest rate is 4% per year. So in 1 quarter
is equal to 0.25 year.
<span>(4% / year) (0.25 year/ 1
quarter) = 1% per quarter</span>
