Help me if you can, "Margo practies her flute 1/4 hour a day.
Write and solve an equation to find how many hours Margo practices her flute in 1 week."

Answer:

4.2 units

most likely answer choice B

Step-by-step explanation:

(1, 2) and (4, 5)

To find the distance between two points, we use the distance formula:

[tex]d = \sqrt{(x_{2}-x_1)^2 + (y_2-y_1)^2 }[/tex]

Let's plug in what we know.

[tex]d = \sqrt{(4 - 1)^2 + (5 - 2)^2 }[/tex]

Evaluate the parentheses.

[tex]d = \sqrt{(3)^2 + (3)^2 }[/tex]

Evaluate the exponents.

[tex]d = \sqrt{(9) + (9) }[/tex]

Add.

[tex]d=\sqrt{18}[/tex]

Evaluate the radical.

d = 4.24

Round to the nearest tenth.

d = 4.2 units

*note: The answer choice is 4.6. I'm not sure if that is a typo on someone's end, but the distance between these two points is exactly 4.24264068712 units.

Answer:

2.) 145°

4.) 50°

Step-by-step explanation:

2.) First find the measure of Angle Y, since they are supplementary;

∠Z + ∠Y = 180

35 + ∠Y = 180

∠Y = 180 - 35

∠Y = 145°

So ∠X would be 145° as well

4.) First find the measure of Angle F, since they are supplementary;

∠C + ∠F = 180

130 + ∠F  = 180

∠F = 180 -130

∠F = 50°

So ∠E would be 50°

(I didn't explain it much in detail, since this question is similar to the previous that i answered :)

Answer:

The product of 10 and a number is = 10x Twice that number means 2x 36 less than twice that number= 2x-36. It is given that....The product of 10 and a number is the same as 36 less twice that same number

Step-by-step explanation:

The required number that is Nine times the difference of a number and 4 is the same as the product of 2 and the same number plus 10, is 8.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

Here,
Let the number x,
According to the question,
9 (x - 4) = 2(x + 10)
Simplifying,
9x - 36 = 2x + 20
9x - 2x = 36 + 20
7x = 56
x = 56 / 7
x = 8

Thus, the required number that is Nine times the difference of a number and 4 is the same as the product of 2 and the same number plus 10, is 8.

Answer:

360°

Step-by-step explanation:

The exteriors angles of a pentagon are (m + 5)°, (2m + 3)°, (3m + 2)°, (4m + 1)° and (5m + 4)° respectively. Find the measure of each angle. Hints: The sum of all exterior angles of a polygon is 360°.

Step-by-step explanation:

The pentagon is not a regular one. If it were, all the angles would be 72, In addition you have to assume that when m has been solved that the m is constant for all angles.

m + 5 + 2m + 3 +3m+2 + 4m + 1 + 5m+ 4 =360

15m + 15 = 360 Subtract 15 from both sides

15m = 360 - 15 Combine

15m = 345 Divide by 15

m = 23

Answer

m + 5 = 28

2m + 3 =49

3m + 2 = 71

4m + 1 = 93

5m + 4 = 119

The total does come to 360

Answer:

a = 5, b = -3 and c =1

Step-by-step explanation:

The standard form of a quadratic equation is expressed as;

f(x) = ax² + bx + c

Given the expression

f(x) = 5x² = 3x - 1

f(x) =  5x² - 3x + 1

Comparing with the general formula;

ax² = 5x²

a = 5

bx = -3x

b = -3

c = 1

Hence a = 5, b = -3 and c =1

In the diagram, the measure of angle R is 53°

From the question, we are to determine the measure of angle R

Using the law of sines, we can write that

[tex]\frac{sin R}{r} =\frac{sin S}{s}[/tex]

In the given diagram,

r = 30

S = 69°

s = 35

Thus,

[tex]\frac{sin R}{30} =\frac{sin 69^\circ}{35}[/tex]

[tex]sin R =\frac{30 \times sin 69^\circ}{35}[/tex]

sin R = 0.8002

R = sin⁻¹(0.8002)

R = 53.149°

R ≈ 53°

Hence, the measure of angle R is 53°

Answer:

Number of cans of glycol solution needed = 24 cans

Step-by-step explanation:

Total glycol solution needed = 42 gallons

Volume of each can of glycol solution = 1.75 gallon

How many cans will be​ needed

Number of cans of glycol solution needed = Total glycol solution needed / Volume of each can of glycol solution

= 42 / 1.75

= 24

Number of cans of glycol solution needed = 24 cans

Answer:

$800.00

Step-by-step explanation:

3 people for 10 days costs $600. $600/3 = $200 for each person to stay 10 days. Then, 200/10 = $20 per person, per day.

5 people staying 8 days would be $20 per person multiplied by 8 days, so 20 x 5 x 8 which is 800

The required cost of 5 people staying for 8 days is $800.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
According to the question,
Cost of hotel for 1 person = 600 / [10 × 3] = $20
Cost of the hotel for 5 people for 8 days = 20 × 5 × 8 = $800

Thus, the required cost of 5 people staying for 8 days is $800.
