Answer: OMG i hope they are nice to you

Step-by-step explanation:

Answer:

a. 4 : 1

b. 2 students

c. 3 : 1

Step-by-step explanation:

a. There were 12 students who got a C and 3 students who got As. The ratio is therefore:

12 : 3

Take it to the lowest form by dividing both sides by 3:

= 4 : 1

b. There were 4 students with a D grade and 8 with a B. The ratio is:

= 4 : 8

Taken to the lowest form that would be:

= 1 : 2

This means that for every student receiving a D, 2 students received an A.

c. 12 students received a C and 4 students received a D. That ratio is therefore:

= 12 : 4

Take to the lowest form by dividing both sides by 4:

= 3 : 1

Answer:

680

Step-by-step explanation:

85x8

Answer: 680 cubic feet

Step-by-step explanation:

Luke charged an amount of $37.18 in sales tax which is determined by the evaluation of 6.25% of 595.

The percentage is defined as a ratio expressed as a fraction of 100.

For example, If Saima obtained a score of 57% on her exam, that corresponds to 67 out of 100. It is expressed as 57/100 in fractional form and as 57:100 in ratio form.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

Luke bought a computer for $525 and two computer games for $34.99 each. The sales tax rate was 6.25%.

⇒ 525 + 2×34.99 = 595

We have to determine the evaluation of 6.25% of 595.

⇒ 6.25% of 595

6.25%  is expressed as 6.25/100 in fractional form

⇒ (6.25/100)(595)

6.25/100  is expressed as 0.0625 in decimal form

⇒ (0.0625 )(595)

Apply the multiplication operation, and we get

⇒ 37.18

Therefore, Luke charged an amount of $37.18 in sales tax.

Answer:

42 feet of string

Step-by-step explanation:

First, draw a diagram of the string, the height and the angle.

the length of the string is equal to the hypotenuse of the triangle

let length of the string=x

sin(θ)=opp/hyp

sin(72°)=40ft/x

x=40ft/sin(72°)

x=42.05848897ft≈42ft

Answer:

[tex]z = \frac{q}{2} [/tex]

Step-by-step explanation:

[tex]z \infty q[/tex]

[tex]z = kq[/tex]

[tex]z = 2 \: and \: q = 1[/tex]

[tex]2 = k1[/tex]

[tex]k = \frac{2}{1} [/tex]

[tex]z = \frac{1}{2} q[/tex]

[tex]z = \frac{q}{2} [/tex]

9514 1404 393

Answer:

  z = 2q

Step-by-step explanation:

The formula for direct variation is ...

  z = kq . . . . . k is the constant of proportionality

We can find k using the given values of z and q:

  k = z/q = 2/1 = 2

Then the equation connecting z and q is ...

  z = 2q

Answer:

4.2

Step-by-step explanation:

Hypotenuse ² = opposite ² + adjacent ²

Opposite = 3

Adjacent = 3

Hypotenuse ² = opposite ² + adjacent ²

Hypotenuse ² = 3² + 3²

Hypotenuse ² = 9 + 9

Hypotenuse ² = 18

Find the square root of both sides

√Hypotenuse² = √18

Hypotenuse = √18

Hypotenuse = 4.2426406871192

Hypotenuse = 4.2 to the nearest tenth

Answer: 80

Step-by-step explanation:

First, find the area of the square by doing 12 x 12. (Which = 144)

Then, find the area of the circle. This is found by using the formula of 1/4 • π • 9 squared.

This should get you 63.62, or 64 when rounded up.

You then subtract 64 from 144 and get 80 for your answer.

14cm

Answer:

Step-by-step explanation:

Like terms are terms that have the same variable raised to the same exponent. For example, 7z and 2z are like terms because they have the same variable, z, and are raised to the same exponent, 1. 5x² and 10x are not though, because the first one is raised to a power of 2, whereas the latter is only raised to a power of 1. And numbers with different variables, like 7x and 3z, are not either.

Answer: like terms are terms that have the same variables and powers

For example: 3x and 4x are like terms because they both are x and only x. 12xy and 4y would not be like terms because they don’t share the same variable. if it was 5x ² and 8x ² they would be like terms. i hope this helps!

Answer: y = 1.73*x - 0.46

Step-by-step explanation:

For a linear equation of the form:

y = a*x + b

Where a is the slope and b is the y-intercept.

If we have an angle of A degrees with respect to the x-axis, the slope of the function can be calculated as:

Tan(A) = a.

in this case, we have we have an inclination of 30° to the positive x-axis (measured from the positive y-axis) and we know that the angle between the positive x-axis and the positive y-axis is 90°, then the angle measured from the positive axis will be such that:

A + 30° = 90

A = 90° - 30° = 60°

Then the slope is:

a = Tan(60°) = 1.73

Then we have the equation:

y = 1.73*x + b

And we know that this line passes through the point (2, 3) then we can replace x by 2 and y by 3 in the equation, and find the value of b.

3 = 1.73*2 + b

3 - 1.73*2 = b = -0.46

Then the equation is:

y = 1.73*x - 0.46

Answer:

[tex]y^{6}[/tex]

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]x^{n}[/tex] ⇔ [tex]a^{(m+n)}[/tex]

[tex]\frac{a^{m} }{a^{n} }[/tex] ⇔ [tex]a^{(m-n)}[/tex] , then

[tex]\frac{y^4 y^7}{^5}[/tex]

= [tex]\frac{y^{(4+7)} }{y^5}[/tex]

= [tex]\frac{y^{11} }{y^5}[/tex]

= [tex]y^{(11-5)}[/tex]

= [tex]y^{6}[/tex]

Answer:

t = 150 + 30a

Step-by-step explanation:

Treatment of Pedro costs = Expenditure for tests and medicines + fees given for appointments.

If number of appointments = a

Cost per appointment = $30

Cost of 'a' appointments = $30a

Therefore, equation representing the total cost 't' of the treatment will be,

t = 150 + 30a

Answer: the equation would be 8h=240

Step-by-step explanation:

Answer:

The range of the equation is y ≥ 9 ⇒ C

Step-by-step explanation:

The quadratic equation y = ax² + bx + c, represents by a parabola of vertex (h, k), where h = [tex]\frac{-b}{2a}[/tex] and k is the value of y at x = h

∵ The equation is y = x² + 9

→ Compare it with the form above to find a and b

∴ a = 1 and b = 0

∵ a is a positive number

∴ The parabola has a minimum vertex

→ By using the 1st rule above

∴ The range is y ≥ k

→ Use the rule of h above to find it

∵ h = [tex]\frac{-(0)}{2(1)}[/tex] = [tex]\frac{0}{2}[/tex]

∴ h = 0

→ To find k substitute x by the value of h and y by k

∵ k = (0)² + 9

∴ k = 0 + 9

∴ k = 9

∴ The range of the equation is y ≥ 9
