Answer:

1. 6164 × 10 = 61640

2. 61640 ÷ 7 = 8845.71

Answer = $8845.71

Answer:

i. $ 37,560

ii. $14,400

iii.  $51,960

Step-by-step explanation:

3130 x 12 = 37,560

2% of 720,000 = 14,400

14,400 + 37,560 = $51,960

Answer:

(i) 3 140 × 12 = 37 680

(ii) 720 000 × 2% = 720 000 × 0.02 = 14 400

(iii) 37 680 + 14 400 = 52 080

Answer:

y≥−9+4x/3

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer:

Step-by-step explanation:

For a function to be continuous

The right hand limit f'+(x) must be equal to the left hand limit f'-(x)

The right hand limit exist at where x>3

The resulting function is. x²+a

If x = 3

f'+(3) = 3²+a

f'+(3) = 9+a

For the left hand limit, this exist where

bx+a

f'-(x) =bx+a

f'-(3) = 3b+a

Since f'+(3) = f'-(3)

9+a = 3b+a

9 =3b

b = 9/3

b = 3

At the end point x = -3

For the left hand limit

f-(x)= √-b-x

f-(-3) = √-b-(-3)

f(-3) = √-b+3

For the right hand, the function is bx+a

f'+(x) = bx+a

f+(-3) = -3b + a

Equate both limits

√-b+3 = -3b+a

√-3+3 = -3(3)+a

0 = -9+a

a= 9

Hence a = 9 and b = 3

Answer: (2,1) (1,3)

Step-by-step explanation: Assume that the number of hot dogs is X and the number of water bottles is y.

Answer:

1. slope: (y2-y1)/(x2-x1)

(6,38), (9,32)

(32-38)/(9-6) = -6/3 = -2

38 = -2(6) + b

38 = -12 +b, b = 50

y = -2x + 50

2a. Slope = -80, the slope means how many cars left per hour after closing. Y- intercept = 600, cars in lot during closing.

2b. use the equation: y = -80x + 600

Plug in 3 into the equation

y = -80(3) + 600, y = -240 + 600, y = 360 cars

2c. For it to have 0 cars, plug in 0 for y

0 = -80x + 600

-600 = -80x, solve for x

x = 7.5 hours

Answer:

x=3y

Step-by-step explanation:

Step 1: flip the equation.

2x−5y=y

Step 2: Add 5y to both sides.

2x−5y+5y=y+5y

2x=6y

Step 3: Divide both sides by 2.

2x

$180

Step-by-step explanation

(900 x 2 x 10) / 100

=18000 / 100 = 180

=$180

The interest need to pay is $180.

Simple interest is calculated based on a loan's principal or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay further interest on the interest that has already accrued.

Given:

P = $900

R= 10%

T = 2 years

Using Simple Interest

SI = ( PRT)/100

SI = 900 x 10 x 2 /100

SI = 180

Hence, the interest is $180.

Answer:

S10 = 320

Step-by-step explanation:

The formula for calculating the sum of the nth term of an AP is expressed as

Sn = n/2(2a+(n-1)d))

Given

a = 4

d = 5

n = 10

S10 =10/2{2(5)+(10-1)5}

S10 =5{10+9(6)}

S10 =5{10+54}

S10 = 5(64)

S10 = 320

Hence the sum of the first ten terms of the sequence is 320

Answer:

x=10

Step-by-step explanation:

The lines the angles are on are 180 degrees so

(11x+23) + (7x-23)= 180

Let's rearrange them first

11x+7x + 23-23=180

Combine the like terms

18x + 0=180

Remove the 0

18x=180

Then divide 18 on each side

x=10

Answer: Sometimes

Step-by-step explanation:

A system of equations can intersect at no points; this is when the lines are parallel, which means they have the same slope and different y-intercept.

A system of equations can intersect at one point; this is when the lines have different slopes.

A system of equations can intersect in infinitely many points; this is when the graphs overlay one another, which means they are graphs of the same line.  The two equations would equal the same thing.

Answer: 4.64805 pounds of CO₂ was produced

Step-by-step explanation:

Given that;

wattage = 4694 watt = 4694 /1000 = 4.694 kW

time in use t = 10hrs

CO₂ was produced = ?

Total Energy produced = wattage × time = 4.694 kW × 10hrs =  46.95 kWh

we know that 1 kWh produces 0.99 pounds of CO₂

so

46.95 kWh will produce ⇒ 46.95 kWh × 0.99 = 4.64805 pounds of CO₂

Therefore 4.64805 pounds of CO₂ was produced

Answer:

93%

Step-by-step explanation:

From the question given above, the following data were obtained:

Total number of student = 300

Number of student that can not drive = 21

Percentage of student that can drive =.?

Next, we shall determine the number of student that can drive. This can be obtained as follow:

Total number of student = 300

Number of student that can not drive = 21

Number of student that can drive =?

Number of student that can drive = (Total number of student) – (Number of student that can not drive)

Number of student that can drive = 300 – 21

Number of student that can drive = 279

Finally, we shall determine the percentage of student that can drive as illustrated below:

Total number of student = 300

Number of student that can drive = 279

Percentage of student that can drive =?

Percentage of student that can drive =

279/300 × 100

= 93%

Thus, 93% of the student can drive.

Step-by-step explanation:

When reading the problem it tries to trip you up with the black dot. A line of symetery marks where you can cut the shape in half and have both parts equal. With the black dot a part of the shape there is only one way for a line of symetery to work as it can only be split in half that one way. No other corners have a black dot so there is no other way to split it where it would be symetrical.
