Answer:

The cost of slices of pizza = x = $2.82

The cost of garlic knots = y = $0.55

Step-by-step explanation:

David and joe went to the pizzeria.

Let

The cost of slices of pizza = x

The cost of garlic knots = y

David ordered 3 slices of pizza and 4 garlic knots and paid 10.65.

3x + 4y = 10.65....Equation 1

Joe ordered 2 slices of pizza nd 10 garlic knots and paid 9.30.

2x + 10y = 9.30.... Equation 2

Hence:

3x + 4y = 10.65....Equation 1

2x + 10y = 9.30.... Equation 2

We solve using Elimination method:

Multiply Equation 1 by 2 and Equation 2 by 3 to eliminate x

3x + 4y = 10.65....Equation 1 × 2

2x + 10y = 9.30.... Equation 2 × 3

6x + 8y = 21.30.....Equation 3

6x + 20y = 27.9...Equation 4

Subtract Equation 4 from 3

12y = 6.6

y = $0.55

We solve for x using Equation 1

3x + 4y = 10.65....Equation 1

3x + 4($0.55) = $10.65

How much is the cost of each item

3x + $2.2 = $10.65

3x = $10.65 - $2.2

3x = $8.45

x = $8.45/3

x = $2.8166666667

x = $2.82

The cost of each items

The cost of slices of pizza = x = $2.82

The cost of garlic knots = y = $0.55

Answer:

The change in momentum between 0 ms and 14 ms is 0 kg•m/s

Step-by-step explanation:

Here, we want to calculate the change in momentum using the graphical illustration

This is same as the slope using the two points

Let us have 2 expressions of (x,y)

Mathematically, that will be obtained from the graph as follows;

At 0 ms, we have 0 N

At 14 ms , we also have 0

So the two points we are considering are;

(0,0) and (14,0)

= (0-0)/(14-0) = 0/14 = 0 N/ms

Answer:

y=2x-6

Step-by-step explanation:

To find the slope of the line, we will use two points.

(1,-4), (2,-2)

m= -2+4/2-1

m=2/1 or m= 2

Now that we have the slope, we will need to find b. We can use the point (1,-4) to do that.

-4=2(1)+b

-4=2+b

-6=b

y=2x-6

Answer:

The slope is how much he saves per week (In this case it would be $5 per week)

Step-by-step explanation:

Slope is rise/run or change in y/change in x

In this graph, from x=0 to x=8, the rise or change in y is 40$ and the run or change in x is 8 weeks. So the slope is $40/8 weeks, or $5/week

Answer:

$13540

Step-by-step explanation:

Divide 100 from $59000 in which you get 1% of that worth.  If he gets 6% of that commission rate then he would get $3540 since 1% is $590 and you multiply by 6 to get that number.  Since he makes $10000 a month as stated, you would then add the amount $3540 for his salary to get $13540.

Answer:

$13,540

Step-by-step explanation:

We already know that Jose will earn at least $10,000 per month. Now, we need to find 6% of 59,000. To do this, multiply .06 and 59,000. When we do this, we get 3,540. This means Jose earns $3,540 of off items sold, but he also eared $10,000 more. This means we need to add 10,000 and 3,540. When we do this, we get 13,540. This means Jose earned $13,540 this month. I hope this helps!

Answer:

Difference in volume = 791.28m³

The volume of the larger sphere is 791.28m³ greater than the volume of the smaller sphere.

Step-by-step explanation:

The formula for calculating the volume of a sphere is expressed as;

V = 4/3πr³

r is the radius of the sphere:

For the sphere with radius of 6meters

V = 4/3π(6)³

V = 4/3π(216)

V = 4(3.14)(72)

V = 904.32m³

For the sphere with radius of 3 metres

V = 4/3π(3)³

V = 4/3π(27)

V = 4(3.14)(9)

V = 113.04m³

Get the difference in volume;

The difference of the volumes of the spheres = 904.32m³ - 113.04m³

Difference = 791.28m³

Hence the difference of the volumes of the spheres is 791.28m³

This means that the volume of the larger sphere is 791.28m³ greater than the volume of the smaller sphere.

Answer:

3

Step-by-step explanation:

When finding their H.C.F, we can list out their prime factors first.

12: 2² × 3

15: 3 × 5

60: 2² × 3 × 5

3 is the only common prime factor between 12, 15 and 60, so it is the H.C.F.

Answer:

Rate ≥ 9 miles per hour

Step-by-step explanation:

Eugene wants to ride his bike at least 40 miles today, this means that distance ≥ 40 miles. The first hour was mostly downhill, and he rode 13 miles. He has 3 more hours to ride. Write and solve an inequality to find how many miles per hour Eugene

needs to ride to meet his goal.

Solution:

Eugene needs to ride at least 40 miles today. During the first hour he rode 13 miles. The remaining distance is:

Remaining distance ≥ 40 - 13

Remaining distance ≥ 27 miles

Since he has 3 more hours to ride; to meet his goal, the rate he needs to ride is:

Rate ≥ 27 miles / 3 hours

Rate ≥ 9 miles per hour

Step-by-step explanation:

Answer:

The tomato plant is now 18 inches tall, and it has grew a total of 14 inches.

Step-by-step explanation:

A tomato plant grew from 4 inches high to 1.5 feet tall. We need to find out how many inches 1.5 feet tall is equal to.

1 foot = 12 inches

12 x 1.5 = 18 inches

Therefore, the tomato plant is now 18 inches tall, and it has grew a total of 14 inches.

Hope this helps! :D

Answer:

320units³

Step-by-step explanation:

Volume of a sphere V = 4/3πr³

40 = 4/3πr³

120 = 4πr³

30 = πr³

r³ = 30/π

r³ = 30/3.14

r = 2.12

r is the radius of the sphere

Since we are to find the volume of a sphere with twice the radius, then;

R = 2r

The formula becomes

V = 4/3π(2r)³

V = 4/3π8r³

V = 32π(2.12)³/3

Given

V = 32π(9.55)/3

V = 320units³

Hence the required volume is 320units³

Answer:

y = -(1/2)x - 3

Step-by-step explanation:

it is the function for the two points.

The function is  y = -x/2 -3 for the line that includes points of (4,-5) and (8,-7).

A line's slope is how steeply it slopes from LEFT to RIGHT. The slope of a line is determined by dividing its rise, or vertical change, by its run, or horizontal change.

If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,

then the equation of line is

y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)

To find the slope;

m =  (y₂- y₁) / (x₂ - x₁)

Here, we have two points  (4,-5) and (8,-7).

Then the equation of line is:

y +5 = (-7+5) / (8-4) x (x - 4)

y + 5 = -1/2 (x-4)

y = -x/2 -3

Therefore, the required function is y = -x/2 -3.

Answer:

Number of student (not Bike) = 12

Number of student (Bike) = 84

Total student = 96

Step-by-step explanation:

Given:

Probability of student have bike = 7/8

Computation:

Assume;

Number of student (Bike) = a

Number of student (not Bike) = b

So,

a-b = 72

So,

a / (a+b) = 7/8

8a = 7a + 7b

a = 7b

So,

a-b = 72

7b - b = 72

6b = 72

b = 12

Number of student (not Bike) = 12

Number of student (Bike)

a -12 = 72

a = 84

Number of student (Bike) = 84

Total student = 84 + 12

Total student = 96

Answer:

2.3 repeating

Step-by-step explanation:

13x - 2(8 + 5x) = 12 - 11x

13x - 16 + 10x = 12 - 11x

23x - 16 = 12 - 11x

-11x                   -11x

12x - 16 = 12
