Answer:

Inequality: [tex]250\geq s+85\\[/tex]

Solution:[tex]s\leq 165[/tex]

Step-by-step explanation:

The maximum number of students is 250 so the number of students (s) who can still participate plus the number already registered must be less than 250. This can be written as [tex]250\geq s+85\\[/tex].

Form here solve for s by subtracting 85 from both sides.

[tex]250-85\geq s[/tex]

250-85=165

[tex]s\leq 165[/tex]

Answer:

c= 20h + 60

Step-by-step explanation:

The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.

Answer:C

Step-by-step explanation:

Answer:

Monthly payment is $247.53

Step-by-step explanation:

Firstly, we need to calculate the total amount to be paid back

we have this by calculating using the compound interest formula;

That will be;

A = P( 1 + r/n)^nt

where A is the amount to be paid back

P is the amount borrowed = $8,000

r is the interest rate = 3.6% = 3.6/100 = 0.036

n is the number of times we are compounding per year; since it is monthly, this is 12

t is the number of months which is 3

Substituting these values, we have

A = 8000( 1 + 0.036/12)^(12 * 3)

A = 8000(1 + 0.003)^36

A = 8000( 1.003)^36

A = $8,910.94

To know the monthly payment, we divide this by the number of months

That will be;

$8,910.94/36

= $247.53

Answer:

5%

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 5%/100 = 0.05 per year,

then, solving our equation

I = 2000 × 0.05 × 5 = 500

I = $ 500.00

The simple interest accumulated

on a principal of $ 2,000.00

at a rate of 5% per year

for 5 years is $ 500.00.

Answer:the answer is c u can check on a calculator

Step-by-step explanation:

Step-by-step explanation:

x + y = 9. => 2x + 2y = 18.

2x + 2y = 18

- (2x - 3y = -12)

=> 5y = 30, y = 6.

Therefore x + (6) = 9, x = 3.

The solution is x = 3 and y = 6.

Answer:

t = 36

Step-by-step explanation:

If you divide the equation by 5, you have ...

 x^2 -7.2x +t/5 = 0

The opposite of the sum of the roots is the coefficient of the linear term, so is 7.2. If the roots are "r" and "5r", then their sum is r+5r = 6r, so the value of r is.

 7.2/6 = 1.2

The roots are 1.2 and 5·1.2 = 6.

The constant term t/5 is the product of the roots, so ...

 t/5 = 1.2 · 6

 t = 6·6 = 36 . . . . . multiply by 5

Step-by-step explanation:

(a)90 by 10%

90+10% of 90=90(1+0.1)=99

(b)60 by 25%

60(1+0.25)=75

(c)80 by 75%

80(1+0.75)=140

(e)110 by 60%

110(1+0.6)=176

(f)480 by 115%

480(1+1.15)=1032

(g)140 by 45%

140(1+0.45)=203

Answer:

B

Step-by-step explanation:

Answer:

A= y= -2x+7.

B= y= -[tex]\frac{3}{2}[/tex]x+ 6

Step-by-step explanation:

The linear equation is y=mx+b

A= y= -2x+7.

-2 represents he slope and 7 represents the y intercept.

B= y= -[tex]\frac{3}{2}[/tex]x+ 6

-[tex]\frac{3}{2}[/tex] is the slop and 6 is the y intercept.

7 grade you learn it I think

Dunno what you mean by the question but I think that's what your asking

Answer:

1) Velocity = 132 m/sec

2) Direction angle = 24° South of West

Step-by-step explanation:

1) The speed with which the plane is flying, [tex]v_{plane}[/tex] = 120 m/sec

The direction in which the plane is flying = Due West

The speed of the blowing strong wind, [tex]v_{wind}[/tex] = 54 m/s

The direction of the strong wind = Due South

The vector form of the given velocities are;

[tex]v_{plane}[/tex] = -120·i

[tex]v_{wind}[/tex] = 54·j

The resultant velocity in vector format, [tex]\underset{\textbf{v}}{\rightarrow}[/tex] is given as follows;

[tex]\underset{\textbf{v}}{\rightarrow}[/tex] = -120·i + 54·j

Therefore, the magnitude of the resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex], is given as follows;

[tex]\left |\underset{v}{\rightarrow} \right |[/tex] = √((-120)² + (54)²) = 131.590273197

∴ The magnitude of the plane's resultant velocity, [tex]\left |\underset{v}{\rightarrow} \right |[/tex] ≈ 132 m/sec, when rounded to the nearest whole number

2) The direction angle of the plane's resultant velocity, θ, is given as follows;

[tex]\theta = arctan \left ( \dfrac{\left |v_{wind}\right |}{\left |v_{plane}\right |} \right)[/tex]

Therefore, by substituting the known values, we have;

[tex]\theta = arctan \left ( -\dfrac{54}{120} \right) = -24.227745317954169522385424019918 ^{\circ}[/tex]

∴ By rounding to the nearest whole number, the direction angle of the plane's resultant velocity = θ ≈ -24° = 204° which is 24° South of West.

The algebraic representation which matches the above reflection is D. (x, y) → (-x, -y).

Reflection is a type of geometric transformation where the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.

From the graph, it is seen that a quadrilateral is reflected across the Y axis.

Find the corresponding coordinate points of the quadrilateral in order to find the algebraic representation.

From the first figure, consider the vertex point (1, 1).

The corresponding point on the second figure is (-1, -1).

That is, the point (x, y) is changed to (-x, -y).

So the representation is (x, y) → (-x, -y).

Hence the correct algebraic representation is (x, y) → (-x, -y).

Answer:

The number of apples the fruitier have at first is 348 apples

Step-by-step explanation:

The given parameters are;

The ration of the apples to pears the fruitier has = 2:5

The number of pears he sold = 261 pears

The number of apples he bought = 261 apples

The new ratio of apples to pears the fruitier then has =  1:1

Let 'x', represent the initial number of apples the fruitier has at first, and let 'y', represent the initial number of pears the fruitier has at first

Therefore, we have; x:y = 2:5

x/y = 2/5

∴ 5·x = 2·y

x = 2·y/5...(1)

(x + 261):(y - 261) = 1:1

∴ (x + 261)/(y - 261) = 1

x + 261 = y - 261...(2)

Substituting the value of 'x' from equation (1) in equation (2), gives;

2·y/5 + 261 = y - 261

261 + 261 = y - 2·y/5 = 3·y/5

522 = 3·y/5

∴ y = 5 × 522/3 = 870

The number of pears the fruitier have at first, y = 870 pears

x = 2·y/5 = 2 × 870/5 = 348

The number of apples the fruitier have at first, x = 348 apples.

Answer: Rise is 6

Step-by-step explanation:

3=rise and 4 is run so if run becomes 8 then rise is 6

Step-by-step explanation:

Slope is defined as rise over run.

[tex]m = \frac{y}{x}[/tex]

if the slope (m) is 3/4, and the rise (y) is 8, you might substitute those values into the equation and solve for x.

$53.30 of $1780 is:

Answer:

3%

Step-by-step explanation:

The first step is to write 53.3 as a fraction of 1780, which is simply

53.3/1780

Now we need to multiply the numerator and denominator of the fraction by 10 to get rid of the decimal

53.3/1780 = 53.3/1780 x 10/10=533/17800

Now we just need to convert this fraction to a percentage :

533/17800 = 2.99438202247191

2.99438202247191 to the nearest tenth simpifies to 3

So, $53.3 is about 3% of $1780
