If Bob studied 4 hours, what score could he predict he will receive?

Answer:

0.88m²

Step-by-step explanation:

Area of a trapezium = 1/2(a+b)h

a and b are the parallel sides

h is the height

Given

a = 1m

b = 1.2m

h = 0.8m

Substitute

Area of the trapezium = 1/2(1+1.2)(0.8)

Area of the trapezium = 1/2(2.2)(0.8)

Area of the trapezium = 1.1 * 0.8

Area of the trapezium = 0.88m²

Answer:

680 miles

Step-by-step explanation:

1,875=2.5x+175

Minus 175 each side.

1,700=2.5x

Divide both sides by 2.5

680=x

If the band travels 680 miles for $2.50 each mile, plus the flat fee of 175. The total will be 1,875.

Answer:

12 1/9 [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Answer:

Solution A = 2100

Solution B = 700

Step-by-step explanation:

Given that:

Let :

Millimeter of solution A = a

Millimeter of solution B = b

% alcohol, solution A =. 20% = 0.2

% alcohol solution B, = 14% = 0.14

Resulting millimeter of. Alcohol = 518

a = 3b - - - (1)

0.2a + 0.14b = 518 - - - - (2)

Put a = 3b in (2)

0.2(3b) + 0.14b = 518

0.6b + 0.14b = 518

0.74b = 518

b = 518 / 0.74

b = 700

a = 3b

a = 3(700)

a = 2100

Answer:

-9

Step-by-step explanation:

Given the expression

(x+4)³ = -125

We are to find the value of x

Cube root both sides

³√(x+4)³ = ³√-125

x+4 = -5

Subtract 4 from both sides

x+4-4 = -5-4

x = -9

Hence the real solution to the equation is -9

Answer:

23000

Step-by-step explanation:

The 10^4 indicates that the decimal moves to the right 4 times. So 2.3 x 10^4 to standard/regular form would be 23000.

The ordinary form of : [tex]2.3* 10^{4}[/tex] is 2,30,000

Standard form is like scientific notation and is typically used in science and engineering. A number is written in standard form when it is represented as a decimal number times a power of 10.

The number is in standard form is : [tex]2.3* 10^{4}[/tex]

[tex]2.3* 10^{4}[/tex] = 2.3 x 10000

            = 2,30,000

The standard form of : [tex]2.3* 10^{4}[/tex] is 2,30,000

Answer:

y=-3x-8

Step-by-step explanation:

that's the answer

Answer:

y = - 3x - 8

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 3, 1) and (x₂, y₂ ) = (0, - 8)

m = [tex]\frac{-8-1}{0+3}[/tex] = [tex]\frac{-9}{3}[/tex] = - 3

The line crosses the y- axis at (0, - 8 ) ⇒ c = - 8

y = - 3x - 8 ← equation of line

Answer: 7= 1(5)+b

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

y = mx + b

Given that the coordinate is (5, -7), you know that x = 5 and y = -7

Variable m represents the slope, so m = -1

Now simply plug in all the numbers:

y = mx + b

-7 = (-1)(5) + b

Answer:

12:30 PM

Step-by-step explanation:

The capacity of pond= 3600 gallon

The Burt is started at 8:30 AM  and filled 1800 gallons till 10:30 AM

So, in 2 hours the Burt had filled 1800 gallons.

So, rate of filling = 1800/2=900 gallon/hour

The remaining volume of the pond = 3600-1800 = 1800 gallons

Time to fill the remaining volume = 1800/900=2 hour.

So, it will take 2 hours after 10:30 AM to fill the pond completely.

Hence. the pond will be filled at 12:30 PM.
