Kevin gave Ben $4.90 in dimes and quarters. If 10 coins are quarters, how many coins were dimes? Which equation models this problem?
4.90•10=25d
5d+250=4.90
25+5d=4.90
0.25•10+0.1•d=4.90

Answers

Answer 1

i think it's 0.25•10+0.1•d=4.90

Answer 2

Remark

4.90 is all by itself. It is the total amount of money.  It should not be multiplied or divided by anything. So A is wrong.

B: requires a decimal place somewhere in the 490. It would take quite a few dimes to make up 490 dollars. B is wrong.

C: 25 is a decimal (0.25) without a multiplication by 10 present. The 25 should not be alone in any event. C is wrong.

D: is the correct answer. It is what you must use to find out how many dimes there are. Although did not ask for it, you need 24 dimes.

three soccer player alberto,ben,chike are forming a wall to defend against a penalty kick how many different ways can they line up side by side

Answers

In 27 different ways  Alberto, Ben, and Chike can form a wall to defend against a penalty kick.

What are permutation and combination?

A permutation is an arrangement of things where order matters, AB and BA are two different permutations.

The combination is a selection of things where order does not matter, AB and BA are the same combinations.

Given, three soccer players Alberto, Ben, Chike are forming a wall to defend against a penalty kick.

∴ The first place can be filled in 3 different ways.

Second and third place can also be filled with 3 different ways as repetition isn't allowed is not mentioned.

So, In 3×3×3 ways they line up side by side which is 27 different ways.

Final answer:

There are six different ways Alberto, Ben, and Chike can line up to form a wall defending against a penalty kick. This is a high school level Mathematical problem known as permutation. This kind of logic applies whenever the order of arrangement matters.

Explanation:

The subject matter involves a combinatorial problem, specifically a permutation. In this situation, Alberto, Ben, and Chike can occupy any of the three positions in the lineup. As such, the number of permutations (P) can be calculated by multiplying the number of choices for each position. That is, there are three choices for the first position, two remaining for the second, and one for the third. Thus, the answer is P = 3*2*1 = 6 different ways.

Answer:

Refer below

Step-by-step explanation:

5) 9x+2 = 119 (alternate angles of a parallel line)

Hence 9x = 117: x=29 degrees.

6) 12x-8 and 108 are supplementary

Hence 12x+100 = 180 Or 12x= 80 :

x = 20/3

7) 5x+7 = 8x -71

(since vertically opposite angles equal and corresponding angles equal)

3x= 78 or x = 26

8) 7x-61 = 4x-7:3x= 54 orx = 18

9) 9x+25 = 13x-19

4x = 44: x=11:  17y+5 = 13(11)-19

y -7

10) 9x-36 =180 : x = 24: 8y+17 = 6(24)-7

8y =120: y =15

11) 7x-23 =49+3x(exterior angle of triangle)

Or 4x = 72: x=18 : 3x =11y-1

y =5

12) 5x-38 = 3x-4

2x = 34 or x =17

7y-20 = 5(17)-38

= 47

y = 67/7

How do you graph the inequality of 4x-2y≤6 ?

Answers

4x - 2y ≤ 6      subtract 4x from both sides

-2y ≤ -4x + 6     change the signs

2y ≥ 4x - 6     divide both sides by 2

y ≥ 2x - 3

y = 2x - 3 - it's a linear function. We need only two points to plot the graph.

Choose any two values of x and calculate the values of y:

for x = 0 → y = 2(0) - 3 = 0 - 3 = -3 → (0, -3)

for x = 2 → y = 2(2) - 3 = 4 - 3 = 1 → (2, 1)

Find the probability a random voltage is less than 124.2 volts
A. 0.40
B. 0.60
C. 0.10
D. 0.80

Answers

Answer:

its 0.60

Step-by-step explanation:

I did the quiz

Final answer:

The probability a random voltage is less than 124.2 volts is 0.60. Thus, option (C) is correct.

Explanation:

To find the probability that a random voltage is less than 124.2 volts, we need to know the distribution of the voltages. Let's assume that the distribution follows a normal distribution.

The Z-score formula is

Z = (X - μ) / σ,

where X is the value we are interested in, μ is the mean of the distribution, and σ is the standard deviation.

We want to find the probability that a random voltage is less than 124.2 volts.

Since the voltage is uniformly distributed, we can find this probability by calculating the proportion of the range that is less than 124.2 volts.

The range of the voltage is 125 - 123 = 2 volts.

The proportion of the range that is less than 124.2 volts is

= 124.2 - 123

= 1.2 volts / 2 volts

= 0.60.

Therefore, the probability a random voltage is less than 124.2 volts is 0.60.

A marching band 8-to- 5 step covers 5/8 yd per step.

How many yards does a band member move across the football field if he or she takes 30 1/2 steps?

5/8⋅30 1/2=

Express your answer as a fraction in simplest form.

Answers

Final answer:

After taking 30 1/2 steps, each covering 5/8 yard, a band member moves a total of 19 1/16 yards across the football field.

Explanation:

The student asks how many yards a band member moves across the football field if he or she takes 30 1/2 steps where each step covers 5/8 yard. To find the total distance covered, we multiply the number of steps by the distance per step. Here's the calculation:

First, convert 30 1/2 to an improper fraction: (30 × 2) + 1 = 61/2.Now, multiply 61/2 by 5/8 to find the total yards covered: (61/2) × (5/8) = 305/16.To simplify, divide 305 by 16: the quotient is 19 with a remainder of 1, so the simplified fraction is 19 1/16 yards.

The band member moves 19 1/16 yards across the football field after taking 30 1/2 steps at a 8-to-5 step interval.

3 hours 20 minutes + 1 hour 48 minutes = ___ days
A. .2278
B. .1951
C. .2417
D. .2139

Answers

The answer is C .2417 because you add them then divide by 7

Final answer:

To add 3 hours 20 minutes and 1 hour 48 minutes, you add the hours and minutes separately. Then convert the total to days.

Explanation:

To add 3 hours 20 minutes and 1 hour 48 minutes, you can simply add the hours together and the minutes together separately. Start by adding the hours: 3 + 1 = 4 hours. Then add the minutes: 20 + 48 = 68 minutes. Since there are 60 minutes in an hour, you can convert the excess minutes to hours by dividing by 60: 68 ÷ 60 = 1 hour. This gives a total of 5 hours. Therefore, 3 hours 20 minutes + 1 hour 48 minutes = 5 hours 8 minutes.



To convert this to days, divide the total number of minutes (308) by 60 to get the number of hours (5) and then divide by 24 to get the number of days: 5 ÷ 24 ≈ 0.2083 days.
