Answer:

21.50

Step-by-step explanation:

Let C = cost before markup

1.25 C = 26.88

C = 26.88/1.25 = 21.50

Answer:

$45 - (357.50 - 155) / 4.5

Step-by-step explanation:

First, we have to deduct the amount for parts ($155) by the total ($357.50). Once we find the difference ($202.5), we can now divide it by the amount of hours (4.5). This leaves us with the answer, $45.

Answer:
x = 54°
y = 66°

Step-by-step explanation:

x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)

Answer:

yehwe have decided on this number

Step-by-step explanation:

Given that: {∛(125) + ∛(64) - ∛(1)}^(1/3)

= {∛(5 * 5 * 5) + ∛(4 * 4* 4) -∛(1)}^(1/3)

= {∛(5³) + ∛(4³) - ∛(1)}^(1/3)

[since, ⁿ√(a) = a^(1/n)]

= {(5³)^(1/3) + (4³)^(1/3) - (1)^(1/3)}^(1/3)

[since, (aᵐ)ⁿ = aᵐⁿ}

= {(5)^{3*(1/3)} + (4)^{3*(1/3)} - (1*1*1)}^(1/3)

= {{5)^1 + (4)^1 - 1}^(1/3)

= (5 + 4 -1)^(1/3)

= (9 - 1)^(1/3)

= 8^(1/3)

= (2*2*2)^(1/3)

= (2³)^(1/3)

[since, (aᵐ)ⁿ = aᵐⁿ]

= (2)^{3*(1/3)}

= (2)¹

= 2

Therefore, {∛(125) + ∛(64) - ∛(1)}^(1/3) = 2

Answer: Hence, the simplified form of , {∛(125) + ∛(64) - ∛(1)}^(1/3) is 2.

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.

Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.

Factor completely 5ax² − 20x³ + 2a − 8x.

Take 5x² common from the first two terms and 2 from the last two terms. we have

5ax² − 20x³ + 2a − 8x

5x²(a − 4x) + 2 (a − 4x)

Take (a - 4) common, then we have

(5x² + 2) (y − 4x)

The complete factor of the polynomial 5ax² − 20x³ + 2a − 8x is (5x² + 2) (y − 4x). Then the correct option is C.

Step-by-step explanation:

The result of the multiplication for every number in the table is always the same. For example: 15*1 = 15, 5*3 = 15

Using the correlation coefficient, it is found that we can say that there is a non-strong positive relationship between the scores of a baseball team's games and the batting average of its top player.

It is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.

In this problem, the coefficient is of 0.37, which is positive but less than 0.6, hence there is a non-strong positive relationship between the scores of a baseball team's games and the batting average of its top player.

Answer:

a. 46.89 mph

b. 0.781 mi/min

c. 4126.22 ft/min

d. 68.77 ft/s

e. 1.28 min/mi

Step-by-step explanation:

a. Miles per hour

1. Convert 4 hours and 30 minutes into hours (4.5 hours).

2. Divide the distance traveled by the new time.

MPH = 211 mi / 4.5 hours = 46.89 mph

b. Miles per minute

1. Convert 4 hours and 30 minutes into minutes: (4*60+30) = 270 minutes

2. Divide the distance traveled by the new time

MPM = 211 mi / 270 min =0.781 mi/min

c. feet per minute

1. Use the converted time from part b (270 minutes)

2. Convert the distance traveled from miles to feet: (211*5280=1114080 ft)

3. Divide the converted distance by the converted time

ft/min = 1114080 ft / 270 minutes = 4126.22 ft/min

d. feet per second

1. Convert the time into seconds (270 minutes * 60 sec/min) = 16200 sec

2. Use the converted distance from part c (1114080 ft)

3. Divide the converted distance by the converted time

ft/s  = 1114080 ft / 16200 sec = 68.77 ft/s

e. minutes per mile

1. use the converted time from part b (270 minutes)

2. divide the time by the distance traveled

minutes/mi = 270 min / 211 mi = 1.28 min/mi

Spencer has a bag with 10 marbles. There are 6 white marbles and 4 black marbles.

Spencer picks a marble at random.

Write as a decimal the probability of Spencer picking a black marble

4 Black Marbles

+

6 white Marbles

=10

THE ANSWER IS :

4/10

Lowest Term :

2/5

As a Decimal:

The probability of Spencer picking a black marble is approximately 0.4 or 40%.

To find the probability of Spencer picking a black marble, we can use the formula for probability:

Probability = (Number of favorable outcomes) / (Total number of possible outcomes)

In this case, the number of favorable outcomes (picking a black marble) is 4, as there are 4 black marbles in the bag. The total number of possible outcomes (picking any marble) is 10, as there are 10 marbles in total.

Now, we can calculate the probability:

Probability = 4 / 10

Simplifying the fraction, we get:

Probability = 2 / 5

To express the probability as a decimal, divide the numerator (2) by the denominator (5):

Probability = 2 ÷ 5

Probability ≈ 0.4

The probability represents the likelihood of an event occurring, and in this case, it tells us the chance of Spencer picking a black marble out of the 10 marbles in the bag.

Answer:

1/20 mile

Step-by-step explanation:

Let the Perimeter = P

20 (P) = 8 miles

P = 8/20 miles

Perimeter = 2 (Length) + 2 (width)

2 (3/20) + 2W = 8/20

2W = 8/20 - 6/20

2W = 2/20
