Answer:
B) d=4t
Step-by-step explanation:
let's look at two points
1. t=0, d = 0
2. t = 1, d = 4
slope = change in vertical axis (d)/ change in horizontal axis (t)
change in d = 4 = d₂-d₁
change in t = 1 = t₂-t₁
slope = 4/1 = 4
vertical variable = slope * horizontal variable + horizontal axis intercept
d = 4 * t + horizontal axis intercept
horizontal axis intercept is the vertical axis variable (d) when the horizontal axis variable (t) is at 0. at t=0, d=0
thus, d = 4 * t + 0
d = 4t (B)
The area of the rectangle is length times width, that is
A = L*W
The problem requires the width so
W = A/L
Given that A = 437 sq. cm and L = 19 cm, therefore
W = 437/19 = 23 cm
That is the answer.
Answer:
3.33%
Step-by-step explanation:
Answer:
97, 98
Step-by-step explanation:
a = first number
a + 1 = consecutive number
then:
a + a+1 = 195
2a + 1 = 195
2a = 195 - 1
2a = 194
a = 194/2
a = 97
a + 1 = 98
Check:
97 + 98 = 195
It is called a fact Family
