Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. How much money did she save????
Given:
Normal price of a tv = $200
Coupon = 25% off
To find:
The money saved by Katherine.
Solution:
Katherine buys a tv with a normal price of $200 and she has a 25% off coupon. It means, the money saved by Katherine is 25% of normal price of tv, i.e., $200.
[tex]Saving=25\%\text{ of }200[/tex]
[tex]Saving=\dfrac{25}{100}\times 200[/tex]
[tex]Saving=25\times 2[/tex]
[tex]Saving=50[/tex]
Therefore, the money saved by Katherine is $50.

Insert 16 rational numbers between 2.1 and 2.2
Answer:
We will apply the formula of d=y- x/n+1
Let y be 2.2 and x be 2.1 and n= 16
Then 2.2-2.1/ 16+1
0.1/17
x+d= 2.1 + 0.1 = 2.2
x+2d= 2.1+2×0.1=2.3
x+3d= 2.1+3×0.1=2.4
x+4d= 2.1+4×0.1=2.5
x+5d=2.1+5×0.1=2.6
x+6d=2.1+6×0.1=2.7
x+7d=2.1+7×0.1=2.8
x+8d=2.1+8×0.1=2.9
x+9d=2.1+9×0.1=3
x+10d=2.1+10×0.1=3.1
x+11d=2.1+11×0.1=3.2
x+12d=2.1+12×0.1=3.3
×+13d=2.1+13×0.1=3.4
x+14d=2.1+14×0.1=3.5
x+15d=2.1+15×0.1=3.6
x+16d=2.1+16×0.1=3.7

Fred's car has run out of gasoline. He walks 4 km west and then 3 km south looking for a gasoline station. If he is now h km directly from his starting point, find the value of h
Answer:
5 km
Step-by-step explanation:
From. The question, the triangle formed us a right angled triangle,
h km directly from starting point is the hypotenus, h :
Hypotenus = sqrt(opposite² + Adjacent²)
h = sqrt(4² + 3²)
h = sqrt(16 + 9)
h = sqrt(25)
h = 5 km

Angle K measures 67º and angle L measures 119°.
Circle O is inscribed by quadrilateral L M N K.
What are the measures of angles M and N?
m Angle M = 61o and m Angle N = 113o
m Angle M = 67o and m Angle N = 119o
m Angle M = 113o and m Angle N = 61o
m Angle M = 119o and m Angle N = 67o
Answer:
C. m Angle M = 113o and m Angle N = 61o
Step-by-step explanation:
It's the only answer that makes all the angles added together equal 360 degrees.
67 + 119 + 113 + 61 = 360
Answer:
C
Step-by-step explanation:
find m
A.138
B.141
C.69
D.72
Answer:
C
Step-by-step explanation:
Hello There!
If you look at the image you can see that an inscribed angle is equal to one half of the major arc minus the minor arc
So for this problem here
m∠CAD would be equal to 1/2 (arc CD - arc BD)
so now we just plug in the values
m∠CAD = 1/2 ( 210 - 72)
210-72=138
138/2=69
so m∠CAD = 69
Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?
Answer:
25 feet
Step-by-step explanation:
Given that Sally is at the park standing directly under a kite which is 20 feet overheadSally's dad is flying the kitc and is standing 15 feet from her If both are on level ground, how long is the kite string in feet?
To calculate the length of the kite string, we will apply pythagorean theorem.
Length = sqrt ( 20^2 + 15^2 )
Length = sqrt ( 400 + 225 )
Length = sqrt ( 625 )
Length = 25 feet.
Therefore, the length of the kite string is 25 feet.
A town total allocation for firefighters wages and benefits in a new budget is $600,000. If wages are calculated at $40,000 per firefighter and benefits at $20,000 per firefighter. How many firefighters can the town employ if they spend their whole budget?
Answer:
Number of firefighters= 10
Step-by-step explanation:
Giving the following information:
Total budget= $600,000
Wage per firefighter= $40,000
Benefits per firefighter= $20,000
To calculate the number of firefighters that the town can employ, we need to use the following formula:
Number of firefighters= total budget / total cost per firefighter
Number of firefighters= 600,000 / (40,000 + 20,000)
Number of firefighters= 10
