The slope of the interactive is 6
Let the number of each coin be n.
The total sum of these coins is $4.40. So we can write:
n Nickles + n Dimes + n Quarters = 4.40
0.05n + 0.10n + 0.25n = 4.40
0.40n = 4.40
n = 11
So this means, there are 11 coins of each type.
Answer:
23
Step-by-step explanation:
area of a trapezoid = 1/2 × (a + b) × h
so, we have
96 = 1/2 × ((4x - 1) + (x + 3)) × 6 = (5x + 2) × 3
32 = 5x + 2
30 = 5x
x = 6
a = 4x - 1 = 4×6 - 1 = 24 - 1 = 23
Answer:
According to AD=BC So AC=BD
Step-by-step explanation:
AD = BC and angle ADC = angle BCD
we have to prove AC = BD
let's see ∆ADC and ∆BCD
AD = BC [ given ]
angle ADC = angle BCD [ given ]
CD = CD
from S - A - S
∆ADC congruence ∆BCD
