At a book sale, all paperback books cost d dollars each and all hard books cost 2d dollars each. If Kate paid 7d dollars for 5 books at this sale, how many paperback books did she buy?
Answer:
3 paperback books
Step-by-step explanation:
Let the number of paperback Kate bought be a and the number of hard books be b.
Given that she bought 5 books then
a + b = 5
Also, If Kate paid 7d dollars then
a * d + b * 2d = 7d
Divide through by d
a + 2b = 7
Hence we have 2 equations
a + b = 5
a + 2b = 7
subtract the first from the second
2b - b = 7 - 5
b = 2
since
a + b = 5
a + 2 = 5
a = 5 - 2
= 3
Recall that the number of paperback she bought is a hence this is 3
The probability of rolling a 6 with a six-sided number cube is 1/6 Choose the
likelihood that best describes the probability of this event.
Answer:
UNLIKELY
Step-by-step explanation:
Given that:
Probability of rolling a six with a six sided nuner cube = 1/6
Required outcome / Total possible outcomes
Number of 6 / total sides of number cube = 1/6
The probability value obtained shows that there is a chance of getting a six ; however it is possible at about once in every 6 rolls of the dice.
Hence getting a six isn't impossible but the chance is small. A probability of 1/6 is the smallest that can be obtained for any of each number on the dice. Hence, it could be said that the likelihood is 'UNLIKELY'

h=l/l-2k make k the subject
Answer:
[tex]k=\dfrac{l(h-1)}{2h}[/tex]
Step-by-step explanation:
The given equation is :
[tex]h=\dfrac{l}{l-2k}[/tex] ....(1)
We need to find the value of k.
Cross multiplying equation (1)
[tex]h(l-2k)=l\\\\hl-2hk=l\\\\hl-l=2hk\\\\k=\dfrac{l(h-1)}{2h}[/tex]
So, the value of k is equal to [tex]\dfrac{l(h-1)}{2h}[/tex].

Answer:
98 degrees
Step-by-step explanation:
Since angle LON is a straight angle, that means its measure is 180 degrees. So, the two angles that make up angle LON add up to 180. You can create the following equation:
(3x + 89) + (8x + 58) = 180
Then, add like terms.
3x + 8x = 11x
89 + 58 = 147
11x + 147 = 180
Subtract 147 from both sides.
11x = 180 - 147
Add like terms.
11x = 33
Now, divide by 11 on both sides.
x = 3
Since we now have the value of x, we can plug it into the equation to find angle MON:
MON = 3x + 89
Substitute 3 for x
MON = 3(3) + 89
MON = 9 + 89
MON = 98
Jayden and Derek go to Chipotle. Jayden gets a burrito for $7.49 and Derek gets a lifestyle bowl for $8.29. They each get a drink for $1.79. If they have to pay 8% tax on their meal, what will the total cost be?
Answer:
$18.97
Step-by-step explanation:
Add $7.49, $8.29, and $1.79 together= $17.57.
Then, add the 8% tax. So $17.57+8% of tax= $18.97.
Which statement is true about the angle bisectors of a triangle?
Answer:
Follows are the solution to the given question:
Step-by-step explanation:
There are missing details, which is why its solution is as follows:
When an angle bisector points so, its two sides of the corner are equidistant. Its corner bisector of a triangle angle is a straight line splitting its angle into two congruent directions. In such a single point, calling its incentives, follow three-angle engineers are required of its three triangle angles.

Make three contrectic circles with radius is 2.4cm,3.8cm and 5.4cm
Answer:
uxuccyccvivvivucyxtc
А
is 35% of
B.
then
B
А
is 65:35.
Find 35% of 65, since A= 35 and B= 65.
35%=.35
Multiply that by 65, for the percentage.
65*.35= 22.75
So, 35% of 65= 22.75
22.75 is not equal to 35.
This statement is false.

Answer:
proportional relationship does not exist.
proportional relationship does exist.
proportional relationship does not exist.
proportional relationship does exist.
Step-by-step explanation:
To establish proportionality :
For data 1:
y α x
y = kx ; k = proportionality constant
Take x = 1 ; y = 5
5 = k
k = 5
Hence, to obtain other data points :
y = 5x (if data is proportional ; if otherwise, the data isn't proportional).
Take ; x = 2
y = 5* 2 = 10
10 ≠ 9
Hence, data isn't proportional.
2.)
Data 2:
y α x
y = kx ; k = proportionality constant
Take x = hours 2 ; y = miles = 110
110 = 2k
k = 110/2
k = 55
Take ; x = 5
y = 55*5 = 275
275 = 275 (proportional relationship exist)
3.)
For the graph:
First graph isn't proportional
4 = 2k ; k = 4/2 = 2 ; k = 2
At x = 6
y = 6*2 = 12
From graph ; y = 8 at x = 6
Hence, proportional relationship does not exist.
4.)
For the 2nd graph:
4 = 2k ; k = 4/2 = 2 ; k = 2
At x = 6
y = 6*2 = 12
From graph ; y = 12 at x = 6
Hence, proportional relationship does exist.

Answer:
1,680
Step-by-step explanation:
We know a hummingbird beats its wings 420 times in 30 seconds. To find the unit rate, divide 420 by 30.
420/30
42/3
14 beats/second
Now we know a hummingbird beats its wings 14 times in 1 second. Two minutes equals 120 seconds. Multiply 14 by 120 to get the answer here.
14 * 120
(14 * 12) * 10
168 * 10
1,680 beats
Answer:
1680
Step-by-step explanation:
From the table, we can see that per each 30 seconds, a mocking bird flaps its wings 420 times.
Each minute contains 60 seconds. Therefore, in order to calculate the number of times a mockingbird flaps its wings in 2 minutes, we can
60 seconds x 2 minutes = 120
Then, we can divide this number by 30 to figure out how many times we need to multiply 420 to get our answer.
120/30 = 4
Therefore,
420 x 4 = 1680
