Answer:
3 CDs
Step-by-step explanation:
So, we know that she has 65 dollars. Lets write that on one side of the equation.
Then we know that she wants to buy an unknown amount of CDs that cost 14 dollars. Lets let this unknown amount of CDs equal x.
We also know that she wants to buy one CD worth 23 dollars.
So, here is our equation.
65 = 14x + 23
Lets minus 23 from the right, but we also need to minus 23 from the left to balance out the equation.
42 = 14x
Now lets divide 14 from x, then balance the equation by doing that to 42.
3 = x
Now, we have our unknown CD amount!

When 43,55 and 67 are divided by a certain number, the remainder is 7 in each case. Find the number?
Answers
Answer:
12
Step-by-step explanation:
First subtract 7 from 43, 55 and 67
43 - 7 = 36 ; 55 - 7 = 48 ; 67 - 7 = 60
Now find the GCF of 36 , 48 , 60
36 = 2 * 2 * 3 * 3
48 = 2 * 2 * *2*2 * 3
60 = 2 * 2 * 3 * 5
GCF = 2 * 2 * 3 = 12
The required number is 12
When you divide 43 by 12, the remainder is 7.
When you divide 55 by 12, the remainder is 7
When you divide 67 by 12, the remainder is 7

Answer:
$25.20
Step-by-step explanation:
You do 21 times the decimal form of the fraction 120.
The way you make it decimal form is by moving the decimal places two spaces to the left.
So 1.20
So 21 • 1.20
25.20
So 25.20 is 120% of it

Krystal made 8 quarts of soup on Monday 5 quarts of soup on Tuesday and 5 quarts of soup on Wednesday. If she serves each guest 1 cup of soup how many guests can she serve in all?
Answers
Answer:
To get the answer you need to add these together to find the total number of quarts she made.
8+5+5= 18 quarts of soup.
If everyone gets one cup, then 18 people are able to get soup.
The answer is 18 guests.
Step-by-step explanation:
Hope this helps!
Answer: 72 guests total
Step-by-step explanation: Convert quarts to cups to see how many total cups she has...
1 quart = 4 cups
so we find total quarts she cooked and multiply by 4 to find out how many total cups...
8+5+5=18
18x4=72
she made 72 total cups and each guest gets 1 cup
divide total cups by number of cups per guest...
72/1=72
Based on the diagram below, what is the measure of arc DC?
28 degrees
68 degrees
108 degrees
112 degrees
Answers
Answer:
108 °
Step-by-step explanation:
∠DOC = 180° - 112° = 68°
∠DOC = 1/2(arc AB + arc DC)
68 = 1/2(y + 80 + y)
68 = y + 40
y = 28
arc dc = 80 + 28 = 108 °

Answer(a) BC
km (2)
(b) Write down the three figure bearing of C from A.
Answer(b)
Answers
Answer:
1. BC = 86 Km
2. 090°
Step-by-step explanation:
1. Determination of BC
AB = 27 Km
AC = 82 Km
BC =?
Since the figure is a right angle triangle, we shall determine BC by using pythagoras theory. This is illustrated below:
BC² = AB² + AC²
BC² = 27² + 82²
BC² = 729 + 6724
BC² = 7453
Take the square root of both side
BC = √7453
BC = 86 Km
2. Determination of the bearing of C from A.
From the diagram given above, we can see that angle from A and C is 90°. Thus, the bearing of C from A is 090°

Answers
Answer:
x = 16 and y = 116
Step-by-step explanation
For the trapezoid, the sum of the adjacent side is 180. Hence;
6x+20 + 4x = 180
10x + 20 = 180
10x = 180-20
10x = 160
x = 160/10
x = 16
Also, the sum of opposite side is 180, hence;
4(16)+ y = 180
64 + y = 180
y = 180 - 64
y = 116 degrees
hence x = 16 and y = 116
how many 3 digit even number can be formed from the digit 1 2 3 4 5 6 and 6 can't be repeated
Answers
Answer:
90 numbers
Step-by-step explanation:
Total choices(don’t care about anything)
6*6*6= 216 numbers
Half of these numbers are odd because the odd numbers are just 1,3,5
6*6*3=108
the three is there because there is 3 odd digits
we can subtract this from 216 along with the numbers that have a repeated 6
Repeating 6’scase 1: 66_
66 and any other number
remember: we have 6 choices for the last number
number of choices= 1*1*6=6 (the 1’s are there because 6 is the only digit that can come there).
case 2: 6_6
just like last time we have 1*6*1 choices=6
cool?
case 3: _66
again, we have 6*1*1=6 choices
So, we have 18 numbers where 6 repeats itselfPlan: total numbers minus the odd numbers and 6 repeats
216-108-18=90
answer 90 numbers

Given:
In a parallelogram [tex]PRTV, VQ\perp PR,VS\perp RT[/tex].
To prove:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Solution:
It is given that [tex]VQ\perp PR,VS\perp RT[/tex], it means [tex]\angle PQV[/tex] and [tex]\angle TSV[/tex] are right angle triangles.
In triangle PQV and triangle TSV,
[tex]\angle PQV\cong \angle TSV[/tex] (Right angles)
[tex]\angle QPV\cong \angle STV[/tex] (Opposite angles of a parallelogram)
Two corresponding angles are congruent. So, by AA property of similarity, we get
[tex]\Delta PQV\sim \Delta TSV[/tex]
We know that the corresponding parts of similar triangles are proportional. So,
[tex]\dfrac{PQ}{TS}=\dfrac{PV}{TV}[/tex]
It can be rewritten as:
[tex]\dfrac{PQ}{ST}=\dfrac{PV}{VT}[/tex]
Hence proved.
