Answer:
= $5530
Finds us 8.2%
Step-by-step explanation:
if 8.2 was recommended for utilities then we need to find 8.2% of $65,000
We take 65000 x 0.082 = 5530
Therefore the Mckinney's annual income is 65,000 less $5530 for utilities.
We write it as $5,530 in pen and type in whole amount as $ 5530.
Answer:
$5,330
Step-by-step explanation:
Read this statement:
"The McKinneys' annual income is $65,000."
Now, read this statement:
"Households with incomes from $50,000 to $70,000 spend 8.2% on utilities"
Since $65,000 is between $50,000 and $70,000, the percent you need is 8.2%.
8.2% of $65,000 = 0.082 * $65,000 = $5,330

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

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.
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

The random numbers below represent 15 trials of a basketball simulation conducted using a spinner numbered 0–8. 76645, 46757, 28334, 81357, 52453, 21761, 51537, 62385, 62135, 16687, 41662, 27135, 45445, 33858, 86427 Let the number 1 represent a 3-point basket and the numbers 2–8 represent 2-point baskets. Based on the simulation, what is the probability that at least one of the next 5 baskets made by the team is a 3-pointer? A. 6/15 B. 8/15 C. 5/15 D. 7/15
Answer:
7/15
Step-by-step explanation:
probability of one being a a 3-pointer is
1 2 3 4 5 6 7
7/15
Probability that at least one of the next 5 baskets made by the team is a 3- pointer is 7 / 15.
What is probability?" Probability is a branch of mathematics which represents ratio of number of favourable outcomes to the total number of outcome of any event."
Formula used
Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]
According to the question,
Random number represents 15 trials
Therefore,
Total number of outcomes = 15
At least one of the 5 team baskets made by the team is a 3- pointer
Sample space of favourable outcomes
= { 81357, 21761, 51537, 62135, 16687, 41662, 27135}
Number of favourable outcome = 7
Required probability = 7 / 15

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.

Which number is rational?
Answer:
D
Step-by-step explanation:
0.333... is rational because it can be lined up to the fraction 1/3.
Answer:
D.
Step-by-step explanation:
The definition of a rational number is a number that can be expressed as the ratio of two integers.
We cannot represent pi as a ratio of two integers, so it cannot be A. Apply the same definition and B and C are out.
We know that 0.333... = 1/3. This number can be represented as the ratio of two integers, so this is the correct answer.

Two angles add to 90°. The larger angle is 12° more than five times the measure of the smaller angle. Find the measure of the two angles.
Answer:
13 and 77 degrees
Step-by-step explanation:
First, you start by subtracting 12 from the 90..
90 - 12 = 78
then, take 78 and divide it by 6.
78/6 = 13
13 is the measure of your smaller angle.
multiply 13 by 5 and then add 12 to find the measure of the larger angle.
13 x 5 = 65
65 + 12 = 77
77 is the measure of your larger angle.

Find the 7th term of the geometric sequence a3 =128,r=-1/4
Answer:
Step-by-step explanation:
The general formula for this sequence is a(n) = a(1)*(-1/4)^(n - 1). We don't yet know a(1).
If a(3) = 128, then 128 = a(1)*(-1/4)^(3 - 1), or
128 = a(1)*(1/16)
and so a(1) = 128/16
resulting in the specific formua a(n) = 8(-1/4)^(n - 1)
Now let's find a(7):
a(7) = 8(-1/4)^1 * (-1/4)^(6)
or
a(7) = 8(-1/4)^7

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)

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!
