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

Launching the fuse is an illustration of a quadratic model, and the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)

From the complete question, the zeros of the quadratic function are:

x = 3 and x = 8

Rewrite as:

x - 3 = 0 and x - 8 = 0

So, the quadratic equation is:

f(x) = a(x - 3)(x - 8)

Also from the graph, we have the following point

(x,y) = (4,60)

Substitute 4 for x and 60 for f(x) in the function

a(4 - 3)(4 - 8) = 60

Evaluate the difference

a(1)(-4) = 60

Evaluate the product

-4a = 60

Divide both sides by 4

a = -15

Substitute a = -15 in f(x) = a(x - 3)(x - 8)

f(x) = -15(x - 3)(x - 8)

Hence, the equation of the quadratic model is f(x) = 15(x - 3)(x - 8)

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:

14.18 cm

Step-by-step explanation:

Area = pi r^2

sqrt ( area/pi)  = r

diameter is 2 x r     and circumference is pi * d

circumference      pi *   2 * ( sqrt area/pi)  = 14.18 cm

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

Step-by-step explanation:

Start by evaluating in the parenthesis

First simplify the exponents

[tex]\frac{3}{4} (2^3+4^2)\\\frac{3}{4} (8+16)[/tex]

Now simplify in the parenthesis

[tex]\frac{3}{4} (8+16)\\\frac{3}{4} (24)[/tex]

Now multiply

[tex]\frac{3}{4} (24)\\\frac{72}{4} \\18[/tex]

Step-by-step explanation:

A = 1/2*h(base + base)

Plugging everything in gives you:

1/2*(6.8)(7.5 + 13.7 + 5.3)

((13.7 + 5.3) gives you the bottom base)

First, adding inside the parentheses:

1/2*(6.8)(26.5)

Multiply 6.8 by 26.5(h times bases):

1/2*(180.2)

Lastly, multiply:

A= 90.1 m^2

Step-by-step explanation:

Because D is saying the negative number is less than, we know it is true.

Because B states that -7.1 is more, it is correct. -7.1 is closer to zero than -7.8, making it a larger number.

Answer:

126

Step-by-step explanation:

In math, "of" usually means multiplication.

9/13 of 182 means 9/13 × 182.

9/13 × 182 = 9/13 × 182/1 = (9 × 182)/(13 × 1) = 1638/13 = 126

Answer: 126

Answer:

126

Step-by-step explanation:

To find 9/13 of 182, we would divide 182 by 13 and multiply the quotient by 9.

182 ÷ 13 = 14

14 • 9 = 126

To double-check our answer, we can divide 126 by 182 and see if the fraction is congruent to 9/13.

126 ÷ 182 = 0.6923

9 ÷ 13 = 0.6923
