Answer:

4

Step-by-step explanation:

We need to find the greatest common factor aka (GCF)

Factors of 28: 1, 2, 4, 7, 14, 28

Factors of 12: 1, 2, 3, 4, 6, 12

Factors of 8: 1, 2, 4, 8

Answer:

6[tex]m^{2}[/tex]

Step-by-step explanation:

Any prism volume is V = BH where B is area of base and H is height of prism,

B = 1/2 h(b1+b2) since B is the area of the base

[tex]\frac{v}{h}[/tex]=B if we solve for B from the volume formula

which gives: [tex]\frac{30m^{3} }{5m}[/tex] and the units cancel out to leave 6[tex]m^{2}[/tex] is the area of the base

The speed of the train is given by T = 60 km/hr

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let's call the speed of the car "x" (in km/h).

And the speed of the train is "x+5" (also in km/h).

We can use the formula:

distance = speed x time

To write two equations, one for the distance traveled by the car and one for the distance traveled by the train:

The distance traveled by car C = x × 4

The distance traveled by train T = (x+5) × 7

We know that the total distance traveled is 640 km, so we can write:

x × 4 + (x+5) × 7 = 640

Expanding the brackets and simplifying, we get:

4x + 7x + 35 = 640

11x = 605

x = 55

So the speed of the car is 55 km/h. Using this, we can find the speed of the train:

The speed of train T = speed of car C + 5

The speed of train = 55 + 5

The speed of train = 60 km/h

Hence , the speed of the train is 60 km/hr

Answer:

$6 tickets:  16; $10 tickets:  45

Step-by-step explanation:

We need a system of equations to find the number of each type of ticket sold.

Thus, we have [tex]x+y=60[/tex], where x = the number of $6 tickets and y = the number of $10 tickets

We also have [tex]6x+10y=540[/tex]

We can use the elimination method to find y:

[tex]x+y=60\\6x+10y=540\\\\-6(x+y=60)\\\\-6x-6y=-360\\6x+10y=540\\\\(4y=180) / 4\\\\y=45\\\\(x+45=60)-45\\\\x=15[/tex]

Answer:

Equation would be 1.25m = 6.50.

The taxi traveld 5.2 miles.

Step-by-step explanation:

So we know that they charge 1.25 per mile but we dont know how many miles they traveld.

Our total cost was 6.50. This is imediatly enough information to help build an equation.

Since the amount of the miles travels is unkown, we leave it as "m" but we know it cost 1.25 per mile therfore it makes it 1.25m

Next we do, 1.25m = 6.50 since 6.50 was our total cost.

Now, we solve it! We solve it by simply dividing 1.25 on both sides:

[tex]\frac{1.25m}{1.25}[/tex] = [tex]\frac{6.50}{1.25}[/tex]

When we divide 1.25 by 1.25 we get 1 which leaves it at 0. When we divide 6.50 by 1.25 we get 5.2.

m = 5.2

miles = 5.2

Answer:

∠1, ∠3, ∠5 and ∠7 = 126°

∠2, ∠4, ∠6 and ∠8 = 54°

Step-by-step explanation:

∠3 + ∠4 = 180°

If ∠3 = 126°, ∠4 = 54°

The same applies for ∠1 and ∠2, ∠5 and ∠6, ∠7 and ∠8 respectively.

Therefore,

∠1  = 126°,

∠3 = 126°,

∠5 = 126°, and

∠7 = 126°

∠2 = 54°,

∠4 = 54°,

∠6 = 54°, and

∠8 = 54°

At that point, there would be 417 cookies left. At that rate it would take about 31 minutes.

Answer:

x > 5  should be your solution to the inequality.

Step-by-step explanation:

Your inequality: 14 - 3x < -1

You need to do two-step inequalities which are similar to two-step equations but different since you're using an inequality symbol as opposed to an equal sign.

Steps:

14 - 3x < -1

Subtract 14 from both sides

-3x < -1-14

Solve -1-14

That should be -15

-3x < -15

**You have to switch the inequality due to multiplying negatives rule.

While dealing with inequalities, when multiplying negatives the inequality sign should switch to its opposite.

-3x > -15

x > 5

5 is lesser than x
