Answer:

C.  The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days

Step-by-step explanation:

So 5 time 4 equals 20...!

80 minus 20= 60

The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days, which is the correct answer would be option (C).

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

A student works 80 hours per month and plans to work 5 hours each day, but only on days when work is planned. After working for d days, the function / (d) - 80 — 5d shows the number of hours of work remaining for the month.

⇒ f (d) = 80 - 5d ....(i)

According to option (C),

Substitute the value of d = 4 in equation (i),

⇒ f (4) = 80 - 5(4)

⇒ f (4) = 80 - 20

⇒ f (4) = 60

Thus, the value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days

Hence, the correct answer would be option (C).

The measurement that is closest to the area in square feet that this sprinkler sprays with water is 201.062 ft².

Diameter of the circular area of grass, d = 16 ft.,

For each of these problems, remember SOH-CAH-TOA.

Sine = opposite/hypotenuse

Cosine = adjacent/hypotenuse

Tangent = opposite/adjacent

5) Here we are looking for the cosine of the 30 degree angle. Cosine uses the adjacent side to the angle over the hypotenuse. Therefore, cos(30) = 43/50.

6) We have an unknown side length, of which is adjacent to 22 degrees, and the length of the hypotenuse. Since we know the adjacent side and the hypotenuse, we should use Cosine. Therefore, our equation to find the missing side length is cos(22) = x / 15.

7) When finding an angle, we always use the inverse of the trigonometry function we originally used. Therefore, if sin(A) = 12/15, then the inverse of that would be sin^-1 (12/15) = A.

8) We are again using an inverse trigonometry function here. We know the hypotenuse, as well as the side adjacent to the angle. Therefore, we should use the inverse cosine function. Using the inverse cosine function gives us cos^-1 (9/13) = 46 degrees.

75,900 g

Step-by-step explanation:

m=d×v

(1.38g/cm^3) × (55,000)

The mass of the drum is 75.9 kg.

The mass of the drum is the product of the volume and density of the drum.

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the plastic shreds were placed into 55-liter drums.

We have to determine the mass of the plastic shreds inside one of the drums in kg.

Here density of the drum = 1.38g/cm³ and the volume of the drum = 55,000

The mass of the drum = (1.38g/cm³) × (55,000)

The mass of the drum = 75,900 g

The mass of the drum = 75.9 kg

Using operations with fractions, it is found that the possible steps are:

The equation given is:

[tex]5\frac{1}{2}x + \frac{2}{3}x = 37[/tex]

The improper fraction can be written as:

[tex]5\frac{1}{2} = \frac{5\times 1 + 2}{2} = \frac{11}{2}[/tex]

Then:

[tex]\frac{11}{2}x + \frac{2}{3}x = 37[/tex]

Applying the least common multiple:

[tex]\frac{33x + 4x}{6} = 37[/tex]

[tex]\frac{37x}{6} = 37[/tex]

[tex]37x = 37 \times 6[/tex]

[tex]x = \frac{37 \times 6}{37}[/tex]

[tex]x = 6[/tex]

Answer:

Step-by-step explanation:

hi! to find the sum of the soup mix, we have to add all the fractions together.

7/4 + 1/2 + 5/3 + 1/3 +1/4 + 1/2

we have to find a common denominator for each, which is the LCM of the denominators. this would be 12. let's change the fractions so we can add them up.

21/12 + 6/12 + 20/12 + 4/12 + 3/12 + 6/12

add the numerators and keep the denominators the same.

(21+6+20+4+3+6)/12

60/12

this simplifies to 5.

the total amount of soup mix is 5 cups.

Answer:

5 cups of soup mix

Step-by-step explanation:

Make all the denominators equal. The lowest common denominator is 12 so multiple the denominators with 4 by 3, 2 by 6, and 3 by 4.

[tex]\frac{7}{4} *3=\frac{21}{12}[/tex]

[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]

[tex]\frac{5}{3} *4=\frac{20}{12}[/tex]

[tex]\frac{1}{3} *4=\frac{4}{12}[/tex]

[tex]\frac{1}{4} *3=\frac{3}{12}[/tex]

[tex]\frac{1}{2} *6=\frac{6}{12}[/tex]

Now that all the fractions have the same denominator you can add them all together.

[tex]\frac{21}{12} +\frac{6}{12} +\frac{20}{12} +\frac{4}{12} +\frac{3}{12} +\frac{6}{12}=\frac{60}{12}[/tex]

Then simplify the fraction to find out how many total cups of soup mix you have.

[tex]\frac{60}{12} =5[/tex]

Associative Property

Step-by-step explanation:

The associative property states that it doesn't matter where the parenthesis are put, the answer will always be the same

Answer:

Step-by-step explanation:

A linear equation is of the form ax+b and the highest degree of x is 1. You can see that from the power of x which is 1.

The power of x is zero from the equating. It is not reflecting because anything raise to power if zero gives 1

To get the solution of the equation ax+b = 0

We will make x the subject of the formula

ax = -b

Divide both side's by a

ax/a = -b/a

x = -b/a

If 2x-3 = 0

2x = 0+3

2x = 3

2x/2 = 3/2

x = 3/2

Given -8 = 2x+4

2x = -8-4

2x = -12

x = -12/2

x = -6

A linear equation in one variable is known to have ONE solution. This is as demonstrated in the equation above, we cans see that the only solution is -6(just one solution)

Convert the statement "adding 15 to 4 times x is 39" into an equation 1

The product of 4 and x is 4x

Adding 15 to 4x will give

15+4x

If the resulting expression is equal to 39, the final equation will be;

15+4x = 39

10) given 1/3+S = 2/5, we are to find S

S = 2/5-1/3

S = 6-5/15

S = 1/15

Hence the value of S is 1/15
