Answer:
14 Dimes and 56 Quarters
Step-by-step explanation:
Let D and Q stand for the numbers of Dimes(D) and Quarters(Q). Also, I'll use pennies (not dollars) to eliminate the hassle of decimal points.
We are told that:
10D + 25Q = 1540 [Kendra has $15.40 in dimes and quarters]
We also find that:
Q = 4D [4 times as many quarters as dimes]
Substitute the expression for Q in the second equation into the first:
10D + 25Q = 1540
10D + 25(4D) = 1540
10D + 100D = 1540
110D = 1540
D = 14
Since Q = 4D:
Q = 4(14)
Q = 56
==========
Check:
Does 10D + 25Q = 1540 ?
10(14) + 25(56) = 1540
140 + 1400 = 1540 YES
Does Q = 4D ?
56 = 4(14) YES
whats 2/3 divided by 1/4
Answer:
8/3 or 2 2/3
Step-by-step explanation:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2*4/3*1=8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
Here we will show you how to calculate 2/3 divided by 1/4. We will give you the answer in fraction form and in decimal form.
Here is 2/3 divided by 1/4 displayed mathematically in colors:
2/3 ÷ 1/4
The numbers in 2/3 divided by 1/4 are labeled below:
2 = dividend numerator
3 = dividend denominator
1 = divisor numerator
4 = divisor denominator
To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.
Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:
2 x 4/3 x 1= 8/3
Thus, the answer to 2/3 divided by 1/4 in fraction form is:
8/3
To make the answer to 2/3 divided by 1/4 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:
8/3 = 2.6667
The answer is rounded to the nearest four decimal points if necessary.
8/3 is an improper fraction and should be written as 2 2/3.
Question 2 of 5
Which inequality is true if x = 18?
O A. 25 – x> 8
OB. 0.5x< 7
O C. 6 > 2
OD. I <3
Answer:
C
Step-by-step explanation:
A
25 - x > 8 ( substitute x = 18 )
25 - 18 > 8
7 > 8 ← False statement
B
0.5x < 7 ( substitute x = 18 )
0.5 × 18 < 7
9 < 7 ← False statement
C
[tex]\frac{x}{6}[/tex] > 2 ( substitute x = 18 )
[tex]\frac{18}{6}[/tex] > 2
3 > 2 ← True statement
D
[tex]\frac{x}{4}[/tex] < 3 ( substitute x = 18 )
[tex]\frac{18}{4}[/tex] < 3
4.5 < 3 ← False statement
The only inequality which is true is C
The inequality x/6 >2 is true for the solution x equals to 18. Therefore, the correct answer is option C.
Given that, x=18.
A) 25-x>8
Substitute x=18 in the given inequality, we get
25-18>8
7>8
Which is not true.
B) 0.5x<7
Substitute x=18 in the given inequality, we get
0.5×18<7
9<7
Which is not true.
C) x/6 >2
Substitute x=18 in the given inequality, we get
18/6 >2
3>2
Which is true.
D) x/4 <3
Substitute x=18 in the given inequality, we get
18/4 <3
4.5<3
Which is not true.
Therefore, the correct answer is option C.

#3
[tex]\\ \sf\longmapsto \dfrac{60}{40}=\dfrac{2}{3}\implies R1:R2::3:2[/tex]
Equivalent ratios are ratios of equal unit rates
The equivalent ratios are:

750 : 30, 540 cm : 480 cm and R3,60 : R2,40
Multiply the ratios by 2
1500 : 60, 1080 cm : 960 cm and R7,20 : R4,80
Multiply the ratios by 2
2250 : 90, 1620 cm : 1440 cm and R10,80 : R7,20

A real estate agent received 1.5% commission for a house that sold for $250,000. How much was the agent's commission?
a. $3,750
b. $375
c. $37,500
d. $125,000
Answer:
The answer is B.
Step-by-step explanation:
The answer would be B because dividing 250,000 would get you 25,000 which would be 10% of the total cost. Dividing by 10 again would get you 2500 which would be 1% of the total cost. Divide 2500 by 2 and you'll get 1250. 1250 + 2500 would be 1.5% of the total cost.
Looking at the means of these samples, which value is most likely to be the mean of the population from which the samples were taken? Sample Number Sample Mean 1 11. 8 2 12. 5 3 15. 1 4 14. 3 5 13. 2000 6 12. 9 10. 2 11. 5 12. 9 15. 4.

Comparing SAT and ACT: Suppose that the distribution of scores on the SAT exam is approx. normal with a mean of 1000 and a standard deviation of 160, while the distribution of scores on the ACT exam is approx. normal with a mean of 21 and a standard deviation of 5. Approx 95% of ACT scores fall between two values. What is the value of the lower value
Answer:
11
Step-by-step explanation:
According to the empirical rule, 95% of data in a normal distribution will be between 2 standard deviations below the mean and 2 standard deviations above the mean.
Therefore, 2 standard deviations above the mean would be 21+2(5)=21+10=31 and 2 standard deviations below the mean would be 21-2(5)=21-10=11.
Thus, the lower value is 11

Means and Mean Absolute Deviations of Individual Times of Members of 4 times 200 meter Relay Swim Teams Team A Team B Mean 127. 9 s 127. 4 s Mean Absolute Deviation 0. 26 s 0. 23 s The difference of the means is found and then compared to each of the mean absolute deviations. Which is true? The difference between the mean times is about equal to the mean absolute deviation of the data sets. The difference between the mean times is about 2 times the mean absolute deviation of the data sets. The difference between the mean times is about 5 times the mean absolute deviation of the data sets. The difference between the mean times is about 16 times the mean absolute deviation of the data sets.
A school is buying movie tickets for an excursion.
The school buys a total of 32 tickets. The cost of an adult ticket, a,
is $12.50 and the cost of a student ticket, s, is $8.50. The total
cost of the tickets is $288. Which equations could be used to
find the number of each type of ticket purchased?
Answer:
See below.
Step-by-step explanation:
Two types of tickets are adult(a) and student(s). Let a and s stand for the numbers of tickets bought for each.
We know that a + s = 32 {The school buys a total of 32 tickets.}
The total cost is $288, made up of:
a*($12.50) and s*($8.50)
Thus, we can write:
a*($12.50) + s*($8.50) = $288
The two equations:
a + s = 32
a*($12.50) + s*($8.50) = $288
are all we need to calculate the numbers of a and s tickets.
===
a = 32-s
a*(12.50) + s*(8.50) = 288
(32-s)*(12.50) + s*(8.50) = 288
400 - 4s = 288
-4s = -112
s = 28 tickets
---
a + s = 32
a + 28 = 32
a = 4 tickets
==
Check:
tickets Price Total
a 4 $12.5 $50
2 28 $8.5 $238

Answer:
(d) f(x) = log₆(x)
Step-by-step explanation:
If we use y in place of f(x), we see that ...
x = 6^y
Taking logs of both sides, we get ...
log(x) = y·log(6)
y = log(x)/log(6)
y = log₆(x) . . . . . . . using the change of base formula
f(x) = log₆(x)

What are the midline, amplitude, and period of the graphed sine function?
The midline of the function is at y= ________.
The amplitude of the function is __________.
The period of the function is _________ pi.
The midline, amplitude and period respectively of the given sine graph are; x = 1; 2; π
Midline, Amplitude and Period
The midline of this trigonometric graph is defined as the horizontal line that divides the maximum and minimum point distance into two equal parts. In this case, the midline is x = 1
The amplitude of a graphed function is usually the peak of the wave of that graph. In this case, we see that the peak of the graph is at y = 4. Thus, Amplitude = 4
Period is the difference between two consecutive maximum or minimum points. In this graph, the period is π
