Answer:
Ans. 64 cm
Step-by-step explanation:
we have to use the ratio of actual distance and distance on projection here.
Given,
Ratio of distance in projection and actual distance is 1:200,000
That means, 1 cm in projection will be 200,000 cm in actual distance.
Here,
Actual distance is 128 km.
we know, 1 km=100,000 cm
Now, 128 km=128,00,000 cm
So, actual distance is 128 00 000 cm.
Since, 200000 cm in actual distance means 1 cm in projection.
So,
for 12800000 cm in actual distance means 12800000/200000 cm in projection.
So, in the screen distance will be-
12800000 / 200000
=64 cm
Answer: There are 52 men we can expect to have been involved in a minor traffic accident.
Step-by-step explanation:
Since we have given that
Percentage of men has been involved in a minor traffic accident = 13%
Number of men surveyed = 400
So, Number of sample men we can expect to have been involved in a minor traffic accident is given by
Hence, there are 52 men we can expect to have been involved in a minor traffic accident.
Answer:
If the angle is less than 90 degrees it‘s acute. If it’s exactly 90, it’s a right. And if it is more than 90 degrees it is obtuse.

Answer:
Step-by-step explanation:
let the Cookie Dough kit be x
and Baker’s Delight kit be y
cost of Cookie Dough kit= $7
cost of Baker’s Delight= $15
so
x+y=220------------1
7x+15y=2100------2
solve for x and y we have
multiply eqn 1 by 7 and subtract
7x+7y=1540---------3
- 7x+15y=2100-------2
0x-8y=-560
8y=560
divide both sides by 8 we have
y=560/8
y=70
put y=70 in eqn 1 we have
x+70=220
x=220-70
x=150
x=220-70
x=150
A. How many of each type of kit should your band purchase to raise the most money
Cookie Dough kit= 150
Baker’s Delight= 70
B. What is the most money that your band can raise?
Cookie Dough kit profit= selling price-cost price= 12-7= $5
Baker’s Delight profit= selling price-cost price= 25-15= $10
Amount made for Cookie Dough = 150*5=$750
Amount made for Baker’s Delight = 70*10=$700
total= 750+700= $1450
2x + 9 = 35
We subtract 9 in both sides:
2x + 9 - 9 = 35 - 9
2x = 26
We then divide 2 in both sides:
x = 13
