Answer:

not a real number

Step-by-step explanation:

any negative number under a square root sign, except for 0, isn't real

On evaluating the given roots,

(a) \($-(\sqrt[3]{8}) = -2$\)

(b) \($\sqrt[4]{-81}$\) is not a real number

(a) \($-(\sqrt[3]{8})$\):

The cube root of 8 is the number that, when raised to the power of 3, equals 8. In this case, the cube root of 8 is 2, because \(2^3 = 8\).

Since we have a negative sign in front of the cube root, the result will be the negative value of the cube root of 8.

Therefore, \($-(\sqrt[3]{8}) = -2$\).

(b) \($\sqrt[4]{-81}$\):

The fourth root of a number is the number that, when raised to the power of 4, equals the given number.

In this case, we are looking for the fourth root of -81.

However, the fourth root of a negative number is not a real number. This is because raising a positive number to an even power (in this case, 4) will always result in a positive value, and there is no real number that, when raised to the power of 4, gives a negative result.

Therefore, the fourth root of -81 is not a real number.

Answer:

42.23

Step-by-step explanation:

The bill given after the voucher was used was 36.72.

If we multiply 36.72 with the voucher amount of 15% or .15

36.72*.15=5.508

We then have to add 5.508 to 36.72.

36.72+5.508=42.228=42.23 when rounding up.

Triangles equal 180°. The bottom left corner is 90° in this triangle. Add the angles together set equal to 180°.

x= unknown angle

90° + 67° + x= 180°

157 + x= 180

subtract 157 from both sides

x= 23°

ANSWER: x=23°

If 100 students participate in the fundraiser, each student needs to raise $137.50.If 25 students participate in the fundraiser, each student needs to raise amount $550.

Amount = (Total Amount Needed) ÷ (Number of Students)

For 60 students:

Amount = $275 ÷ 60 = $4.58

For 75 students:

Amount = $275 ÷ 75 = $3.67

For 40 students:

Amount = $275 ÷ 40 = $6.88

To solve this problem, we need to use a simple equation: Amount = (Total Amount Needed) ÷ (Number of Students). We can then plug in the given information to calculate the amount each student needs to raise. For example, if 50 students participate in the fundraiser, we can calculate that each student needs to raise $275 ÷ 50 = $5.50. We can then use this equation to calculate the amount that each student needs to raise if there are different numbers of students participating in the fundraiser. For example, if there are 100 students participating in the fundraiser, each student needs to raise $275 ÷ 100 = $2.75. Similarly, if there are 25 students participating in the fundraiser, each student needs to raise $275 ÷ 25 = $11.00.

Answer:

The flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

Step-by-step explanation:

We can use the following formula to calculate the flow rate:

Flow rate (mL/hr) = Volume to be infused (mL) / Time of infusion (hr)

First, we need to convert the total volume of 2 liters to mL:

2 liters = 2000 mL

Next, we can plug in the values:

Flow rate = 2000 mL / 16 hours

Flow rate = 125 mL/hr

Therefore, the flow rate in mL/hr for infusing 2 liters of 5% dextrose over 16 hours is 125 mL/hr.

The number of pounds of candy that sells for $0.79 per lb that  must be mixed with candy that sells for $1.35 per lb to obtain 8 tons of a mixture that should sell for $335 per ton is 580 pounds

Take x as the number of pounds of candy that sells for $0.79 per lb, and y as the number of pounds of candy that sells for $1.35 per lb.

x + y = 8 (i.e total amount of candy to be mixed)

0.79x + 1.35y = 335 (desired selling price per ton)

solve for x

y = 8 - x

0.79x + 1.35(8 - x) = 335

0.79x + 10.8 - 1.35x = 335

-0.56x = 324.2

x = 579.64

Thus x ≈ 580 to the nearest pound

Hence, about 580 pounds of candy that sells for $0.79 per lb must be mixed with candy that sells for $1.35 per lb to obtain 8 tons of a mixture that should sell for $335 per ton.

Answer:

184

Step-by-step explanation:

y + j + p + a = 1026

y - 60 = j/4 -------> y =  (j/4) + 60

p + 150 = j/2 -----> p = (j/2) - 150

2a = j -------> a = j/2

y = ?

y + p + j + a = 1026

(j/4) + 60 + (j/2) - 150 + j + (j/2) = 1026

(j/4) + j + j - 90 = 1026

(j/4) + 2j = 1116

9j/4 = 1116

9j = 4464

j = 496

y = (496/4) + 60 = 184

The relationship between Steven's charges and time is a proportional relationship. Steven's charge for 5 hours is $52.50.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Steven earns extra money mowing lawns. He charges $31.50 for 3 hours and $84 for 8 hours.

The rate for both conditions is given as,

⇒ 31.50 / 3 = $10.50 per hour

⇒ 84 / 8 = $10.50 per hour

Then the relationship between Steven's charges and time is a proportional relationship.

Steven's charge for 5 hours is given as,

⇒ $10.50 x 5

⇒ $52.50

The relationship between Steven's charges and time is a proportional relationship. Steven's charge for 5 hours is $52.50.

He run on Thursday is 3.75 miles.

Algebra helps in converting a mathematical statement into an equation. We know if we have ‘more’ or ‘sum’ in the given sentence we use addition operation (+) . Similarly If we have ‘less’ or ‘difference’ we use subtraction (−) . If we have a ‘quotient’ we use division operation (÷) . To define more generalized terms; we use algebra. It is a very vast branch of mathematics and is used in all the branches of mathematics like polynomial, linear equations, graphs, etc. and in daily life too.

A. The five-number summary of the data set and what each value represents in the context of the problem are:

B. A box plot that represents the data set from Part A is: B. A horizontal number line starting at 15 with tick marks every one unit up to 51. The values of 16, 20, 24, 37.5, and 50 are all marked by the box plot. The graph is titled Band Donations, and the line is labeled Dollars.

Based on the information provided about the data set, we would use a graphical method (box plot) to determine the five-number summary for the donations received by this middle school during its fundraiser for it's band as follows:

Minimum (Min) = 16.

First quartile (Q₁) = 19.

Median (Med) = 24.

Third quartile (Q₃) = 40.25.

Maximum (Max) = 50.

Part B.

Based on the five-number summary for the donations, we can reasonably infer and logically deduce the second box plot most likely represents the data set from Part A above.

The percent change for this camera is 9.756%.

Markdown percentage is defined as the decrease in the price which is calculated as a percent of the selling price.

Given that,

Original selling price of the camera = $315

Selling price has been decreased to $287

Mark down percentage = (315 - 287) / 287
