Answer:
1. 0.75 cm to 1 km
4. 0.3 mm to 40 m
Step-by-step explanation:
we have the scale
<u><em>Verify each case</em></u>
case 1) 0.75 cm to 1 km
therefore
The scale is equivalent to the given value
case 2) 1 cm to 12 km
therefore
The scale is not equivalent to the given value
case 3) 6 mm to 2 km
Remember that
1 cm= 10 mm
1 mm=0.1 cm
we have
therefore
The scale is not equivalent to the given value
case 4) 0.3 mm to 40 m
Remember that
1 cm= 10 mm -----> 1 mm=0.1 cm
1 km=1,000 m ----> 1 m=0.001 km
we have
therefore
The scale is equivalent to the given value
case 4) 1 inch to 7.62 km
Remember that
1 in= 2.54 cm
we have
therefore
The scale is not equivalent to the given value
Answer:
$3530.3541
Step-by-step explanation:
Given that:
Principal = 2200
Interest rate compounded annually (r) = 3%
Time (t) = 16 years
Using the compound interest formula :
A = P(1 + r/n)^n*t
A = final amount
n = number of times interest is applied per period
A = 2200(1 + 0.03)^16
A = 2200(1.03)^16
A = 2200 * 1.60470643909878751793
A = $3530.3541
Hence, amount in account on his 16th birthday will be $3530. 3541

14/15 - 1/3
= 6/10
In simplest form
= 3/5
Answer:
step 1. y - y1 = m(x - x1). this is the equation given a point and a slope.
step 2. find the slope m. m = (y2 - y1)/(x2 - x1) = (4 - (-4))/(0 - 2) = 8/-2 = -4.
step 3. y - (-4) = -4(x - 2) ; y + 4 = -4x + 8.
step 4. y = -4x + 4.
