Answer:
Step-by-step explanation:
Let us assume that she makes 10 minutes of call.
Telecorp has a flat rate of 7 cents per minute. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.07 × 10 = $0.7
America's charges 25cents per call. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is $0.25
Phone busters charges 35 cents per call and 2 cents per min. If she uses this cell phone service, the amount that she would pay for 10 minutes of call is
0.35 + 10 × 0.02
= 0.35 + 0.2
= $0.55
The cheapest service is that of America's. Therefore, she should choose it.
<span>Hi,
1 cubic yard = 27 cubit feet
Then we must find the no. of cubic yards ....
for 1 cubic yard = $98
for "x" cubic yard = $58.07
1/x =98/58.07
x = 0.5925
Now we have to convert this in to cubic feet...
1 cubic yard = 27 cubic feet
0.5925 cubic yard = x cubic feet
1/0.5925= 27/x
x = 15 .99
cubic feet
now
width x height x length = 16 cubic feet
w x 8 x (1/3) = 16
w = 48/8
= 6 feet
yep!
there for the width of the yard is approximately 6 feet..
hope this will help ya ! </span>
When a line is perpendicular, the slope is the negative reciprocal. Therefore, since the slope is 4, the slope of a line perpendicular is -1/4
Answer:
Step by step explanation:
We have been given that measure of angle A is fifty five degrees, the measure of angle B is eighty degrees and the measure of angle C is x.
Since we know that sum of measures of all the three angles of any triangle equals to 180 degrees.
Let us set sum of measures of all angles of our triangle equal to 180 degrees.
Upon substituting our given values in our equation we will get,
Therefore, the measure of angle x equals to 45 degrees.
Step-by-step explanation:
the scaling ratio is 12/20 = 3/5.
this always applies only to one-dimensional distances, lengths.
the perimeter is calculated as the sum of individual lengths. so while each length is scaled by the same ratio, also the sum is then scaled by that ratio.
p_old = a + b + c
p_new = ra + rb + rc = r(a + b + c) = r×p_old
so, the ratio for the perimeter is also 3/5.
for the area this is a bit different, as an area is always calculated by multiplying 2 lengths (other unscaled factors can be ignored for that consideration of relative change), and that means the scaling ratio has to be multiplied in twice.
a_old = a × b
a_new = ra × rb = r² × a×b = r² × a_old
so, the ratio for the area is
(3/5)² = 9/25
