Answer:
Mikaya and Olivia are correct to be suspicious
Step-by-step explanation:
Sum of the angles of a triangle is always 180
But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180
So, Zuri is wrong
Answer:
nominal rate of interest is 31.7 %
Step-by-step explanation:
given data
payment = $1000
time = 2 year
rate = 4%
CPI = 100
CPI final yer = 127.7
to find out
nominal rate of interest
solution
we know nominal rate of interest formula that is
nominal rate of interest = real interest rate + inflation rate .........1
so here inflation rate is express as
inflation rate = ( CPI final year - CPI ) / CPI × 100 ...........2
put here value
inflation rate = ( 127.7 - 100 ) / 100 × 100
inflation rate is 27.7 %
so from equation 1
nominal rate of interest = real interest rate + inflation rate
nominal rate of interest = 4% + 27.7%
nominal rate of interest is 31.7 %
180-70-30=80
The answer is 80
The two triangles are the same.
Corresponding angles of congruent triangles are equal.
A triangle's three angles add up to 180 degrees.
Answer: the cost per unit of gas is $0.38
Step-by-step explanation:
Let x represent the cost per unit of electricity.
Let y represent the cost per unit of gas.
During one month, a homeowner used 600 units of electricity and 100 units of gas for a total cost of $344. It means that
600x + 100y = 344- - - - - - - - - -1
The next month, 400 units of electricity and 250 units of gas were used for a total cost of $299.
It means that
400x + 250y = 299- - - - - - - - - -1
Multiplying equation 1 by 400 and equation 2 by 600, it becomes
240000x + 40000y = 137600
240000x + 150000y = 179400
Subtracting, it becomes
- 110000y = - 41800
y = - 41800/- 110000
y = 0.38
Substituting y = 0.38 into equation 1, it becomes
600x + 100 × 0.38 = 344
600x + 38 = 344
600x = 344 - 38 = 306
x = 306/600
x = 0.51
