Karl’s and eddie’s ages added together are equal to 65. 10 years ago, Karl was twice as old as Eddie. How old are they now
9514 1404 393
Answer:
Karl is 40Eddie is 25Step-by-step explanation:
10 years ago, the sum of their ages was 65 -2·10 = 45.
If Karl was twice as old as Eddie, his contribution was 2/3 of the sum and Eddie's was 1/3. That is, Karl was (2/3)(45) = 30 and Eddie was 15 at that time.
Now, Karl is 40 and Eddie is 25.
__
This can be solved using a system of equations.
e = 65 -k
(k -10) = 2(e -10)
Substituting the first equation into the second gives ...
k -10 = 2((65 -k) -10)
k -10 = 110 -2k . . . . . . . simplify
3k = 120 . . . . . . . . . . . . add 10+2k
k = 40
e = 65 -40 = 25

A store pays a supplier $40.00 for a wagon. The store sells the wagon for $70.00. What is the markup rate?
Answer:
markup 75%
Step-by-step explanation:
The difference in prices is $70-$40=$30.
So, we need to find what percentage of 40 is 30. We do this by dividing: 30/40=0.75, which is 75%. So, the markup is 75%.

Miss Penny inherits £1040
she decides to save some of the money and spend the rest
the ratio of savings to spending money is 5:8
how much does she save and how much does she spend
Answer:
Step-by-step explanation:
first we simplify the ratio
5:8
8/5=1.6
1:1.6 so for every 1 dollar she save she spends 1.6
next we do 1040/1.6=650
1040-650=390
390:650

What is the area of the figure she created?
Answer:
27 FT
Step-by-step explanation:
Area of square = L × W
= 4.5 ft × 4.5 ft
= 20.25 ft
Area of parallelogram = bh (base times height)
= 1.5 ft × 4.5 ft
= 6.75 ft
Total area = 20.25 ft + 6.75 ft
= 27 ft

There is 3 4 of an apple pie left from dinner. Tomorrow, Victor plans to eat 1 4 of the pie that was left. Enter how much of the whole pie he will eat tomorrow.
Answer:
3/16
Step-by-step explanation:
Let the size of the whole apple be T
Given that 3/4 of the apple is left, it means the size left
= 3T/4
Since Victor plans to eat 1/4 of the pie that was left, this amounts to
1/4 * 3T/4
= 3T/16
This means that Victor will eat 3/16 of the whole pie tomorrow

If m∠12 = 123° and m∠6 = 76°, find each measure.
Answer:
the picture is attachedsee the answers in the attachmentFind the length side
Answer:
PR = 6.93 units
PQ = 13.86 units
Step-by-step explanation:
From ΔPQR,
m∠Q = 30°
QR = 12
By applying tangent rule for the given angle in the triangle,
tan(30°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(30°) = [tex]\frac{PR}{QR}[/tex]
[tex]\frac{1}{\sqrt{3}}=\frac{PR}{12}[/tex]
PR = [tex]\frac{12}{\sqrt{3} }[/tex]
PR = 4√3 ≈ 6.93
Now we apply cosine rule,
cos(30°) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{QR}{PQ}[/tex]
[tex]\frac{\sqrt{3} }{2}=\frac{12}{PQ}[/tex]
PQ = [tex]\frac{24}{\sqrt{3} }[/tex]
PQ = 8√3 ≈ 13.86
Find the value of x.

65°
Answer:
The answer is x= 10.6
Step-by-step explanation:
because C and D are both bigger numbers then the side that is given so those are eliminated and you're left with A and B and there is no way it can be B because thats to big of a number so its A
If ray OC stands on line AB such that ∠AOC = ∠BOC, then find ∠BOC.
Answer:
Here OP bisect ∠BOC
∴∠POC=∠BOP …………(i)
and OQ bisect ∠AOC
∴∠AOQ=∠COQ …………….(ii)
and ∠AOB=180
o
[∵AOB is a straight line]
⇒∠BOP+∠DOC+∠COQ+∠AOQ=180
o
⇒∠POC+∠POC+∠COQ+∠COQ=180
o
[using (i) & (ii)]
⇒2∠POC+2∠COQ=480
o
⇒2(∠POC+∠COQ)=180
o
⇒2∠POQ=180
o
⇒∠POQ=90
o
