Answer:
$2.10
Step-by-step explanation:
5 beads + 5 pendants cost $19.50
beads cost $1.80 per necklace
5 beads cost 5 * $1.80 = $9.00
cost of 5 pendants = $19.50 - $9.00 = $10.50
cost of 1 pendant = $10.50/5 = $2.10
Answer:
$2.10
Step-by-step explanation:
For each necklace, the price of the beads totaled up to $1.80. Since there were 5 necklaces, the total price for all of the beads is $9.
5 × 1.80 = 9
The total cost of all materials is $19.50. Since we are trying to find the cost of the pendants, subtract the cost of the beads by the total price.
19.50 - 9 = 10.50
Since you are trying to find the cost of each pendant, divide the costs of all the pendants by 5. You are dividing by five because there is one pendant for on necklace.
10.5/5 = 2.10
The cost of a single pendant is $2.10.
Lance bought a used car for $5500. He sold it two years later for $2475. What is the percent change of the price?
Answer: 55%
Step-by-step explanation:
2475/5500 = .45
He sold it for 45% of the price, so it went down by 55%
Three kids play tennis at the same tennis courts. Mark plays every fourth day, David plays every seventh day and Bryan plays every sixth day. All of them were at the tennis court on Wednesday, July 18th. What will be the next day, when all three of them will be at the court together?
Answer:
Wednesday (9 weeks later) = 10th October.
Step-by-step explanation:
We label the days with the initials of the names.
M= 4
D = 7
B = 6
LCM of 6 +7 = 42
LCM of 6+7 + 4 = 84
We find 84 is the amount of days we need to add on to july 18th
We first find the weeks 84/7 = 9 weeks.
As Wednesday July 18th is exclusive it would be 84 days after this event.
18+ 84 = 102 days.
31 days in july = 31
31 days in Aug = 31
30 days in Sept = 30
= 92
102-92 = 10
We now know date is Wednesday 10th October
We can check 84 days = 9 weeks
13 days in July makes 31st july
31 days in Aug makes 31st Aug
30 days in Sept makes 30th Sept
= 74 days + 10 days = 84
10th October is the checked date and we know it is also a Wednesday as Wednesday had stayed exclusive and prove that there are 7 days in the week to account x 9, to account for an exact 9 weeks later duration.
Answer:
Wednesday, October 10
Step-by-step explanation:
David play every 7 days, so since the first day is a Wednesday, David plays every Wednesday. We need to find the smallest common multiple of 4 and 6 that is also a multiple of 7. Since 4 * 3 = 12 and 6 * 2 = 12, we see that all multiples of 12 are also multiples of 4. We list the multiples of 12:
12, 24, 36, 48, 60, 72, 84, 96, ...
The smallest multiple of 12 that is a multiple of 7 is 84.
The first day all of them play together after July 18th is 84 days later.
84/7 = 12
We look in a calendar, and we see that exactly 12 weeks after July 18 is Wednesday, October 10.
Answer: Wednesday, October 10.
(2x-1)(x+5)=o solve for x
Answer:
x = - 5, x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given
(2x - 1)(x + 5) = 0
Equate each factor to zero and solve for x
x + 5 = 0 ⇒ x = - 5
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
Answer:
x = - 5, x = 1/2
Step-by-step explanation:
(2x - 1)(x + 5) = 0
x + 5 = 0 so x = - 5
2x - 1 = 0 so 2x = 1 so x = 1/2

Expand the logarithm fully using the properties of logs. Express the final answer in terms of log x, and log y.
log x^3 y^4
Answer:
log x³ y⁴ = 3 log ( x ) + 4 log( y)
Step-by-step explanation:
Given function log x³ y⁴
step(i):-
Applying logarithmic formula
log ( a b ) = log (a) +log (b)
log x³ y⁴ = log ( x³ ) + log( y⁴)
step(ii):-
Applying logarithmic formula
log (x ⁿ) = n log x
log x³ y⁴ = log ( x³ ) + log( y⁴)
log x³ y⁴ = 3 log ( x ) + 4 log( y)
final answer:-
log x³ y⁴ = 3 log ( x ) + 4 log( y)
A red bus and a yellow bus are both driving on the same road, in the same direction They start driving from the same place and are traveling at a constant speed. The red bust started driving 0.5 hours after the yellow bus started driving. If the red bus drives 50 miles per hour and the yellow bus drives 40 miles per hour, how many miles will each bus have to traveled when the red bus catches up to the yellow bus?
Answer:
100 miles
Step-by-step explanation:
lets find out how much the yellow bus drove before red bus started
40*0.5=20
20 miles
50x=40x+20
10x=20
x=2
they traveled for two hours until red bus caught up with yellow bus
yellow:
2*40+20=80+20=100 miles
red:
2*50=100 miles

I NEED HELP ASAPPP!!!!!
Answer:
it must be 8cm + 9 cm
Step-by-step explanation:
A Triangel has three sides: a, b, c
The rule is, that in the triangle it is always:
a+b>c
a+c>b
b+c>a
The given side is 13 cm, so the two other sides need to be bigger than 13 cm.
5 cm + 8 cm = 13 cm - cannot be the two sides
6 cm + 7 cm = 13 cm - cannot be the two sides
7 cm + 2 cm = 9 cm < 13 cm - cannot be the two sides
8 cm + 9 cm = 17 cm > 13 cm - these are the sides you looked for!
Which of the following best describes the relationship between the chords NR and QS shown in the diagram below?
Answer:
C
Step-by-step explanation:
By observation, we can see very clearly that NR and QS are neither parallel nor perpendicular. Hence we can ignore A and B.
We notice that VT and VU are the same length.
Hence we can conclude that NR and QS must also be the same length (i.e they are congruent)
Therefore C is the answer.
A survey of 125 households was done to investigate whether households have laptops, tablets, or
both. The results are shown in the Venn diagram below. If a household was selected at random, which
of the following would be the probability the household would have a laptop given that it does not
have a tablet?

2) 0.355
3) 0.326
4) 0.172
Answer:
3) 0.326

Total Number of surveyed households =125
We want to determine the probability that a randomly selected household would have a laptop given that it does not have a tablet.
Written in Probability notation: P(Laptop|No Tablet)
[tex]P(Laptop|No Tablet)=\dfrac{P(L\cap T')}{P(T')} \\=\dfrac{31/125}{95/125}\\=\dfrac{31}{95}\\\\=0.326[/tex]

Without using a protractor, you can determine whether the angles are right angles by measuring the length of the diagonal and applying the converse of the Pythagorean Theorem.
The length of both diagonals for each lateral side is 13 centimeters. From this, can you prove that the lateral sides are rectangles? Why or why not?
Answer:
If we have following equation right, then the angle between shorter sides is right angle:
13² = 12² + 5²169 = 144 + 25169 = 169Confirmed
Now we can start,
Assume that if the angle between shorter sides is right angle, then the equation should be equal in both sides.
Let's begin the equation,
→ 13² = 12² + 5²
→ 169 = 144 + 25
→ 169 = 169
→ LHS = RHS
Hence, the statement is proved.

Step-by-step explanation:
The area of the parallelogram is 13 square units
The area of a parallelogram is the product of the height and the base of the parallelogram
Assume the parallelogram has the following properties
Base = 6.5 units
Height = 2 units
The area of the parallelogram is calculated as:
Area = Base * Height
So, we have:
Area = 6.5 units * 2 units
Area = 13 square units
Hence, the area of the parallelogram is 13 square units

William has $7.50 to spend at the pretzel shop. A large pretzel costs $1.25 and a soft drink costs $0.90. He buys one drink and p pretzels. Which inequality can be used to find the number of pretzels William can buy?
1.25p−0.9≤7.5
1.25p+0.9≤7.5
1.25p+0.9≥7.5
1.25+0.9p≤7.5
Answer:
the answer is B
Step-by-step explanation:
the reason is because 1.25 x the amount of pretzels he wants plus his price of his one drink will be less than or equal to the amount of money he has
Answer:
B
Step-by-step explanation:
Cost of p pretzels = 1.25 * p = $ 1.25p
cost of p pretzels and cost of a soft drink should be less than or equal to $7.50
1.25p + 0.90 ≤ 7.50
