The surface area of the triangular prism would be =324,000cm²

To calculate the surface area of the triangular prism the formula that should be given would be as follows:

Surface area of triangular prism;

Surface area of triangular prism;= bh+(b1+b2+b3)l

where:

base length = 20cm

height = 15cm

length = 18cm

SA = 20×15(20+15+25)×18

= 300×60×18

Answer:

Therefore, you need 2600 pounds of 35% supplement and 1300 - 2600 = -1300 pounds of 10% ration.

Step-by-step explanation:

The unknown variable is x, which is the amount of 35% supplement needed. The other expressions are derived from the given information and the fact that the total amount of solution is 1300 pounds.

The equation from the fourth column is:

0.35x + 0.10(1300 - x) = 0.25(1300)

Solving for x, we get:

x = (0.25(1300) - 0.10(1300)) / (0.35 - 0.10) x = 650 / 0.25 x = 2600

The half-life of the radioactive substance is approximately 59.1 hours.

Let's denote the amount of the radioactive substance present at time t by M(t). We know that at time t=0, M(0) = 100 mg.

After 6 hours, the mass decreased by 5%, which means that 95% of the initial mass remains. Therefore, we have:

M(6) = 0.95 x M(0) = 0.95 x 100 mg = 95 mg

We also know that the rate of decay is proportional to the amount of the substance present at time t. This means we can write a differential equation for M(t):

dM/dt = kM

where k is the proportionality constant. The solution to this differential equation is:

M(t) = M(0) e^kt

To find the half-life of the substance, we need to find the value of t for which M(t) = M(0)/2. Substituting this into the equation above, we get:

M(0)/2 = M(0) e^kt

Simplifying and solving for k, we get:

k = ln(1/2) / t1/2

where t1/2 is the half-life of the substance.

Substituting the values we know, we get:

95 = 100 e^6k

Solving for k, we get:

k = ln(95/100) / 6 = -0.0117

Substituting this value of k into the equation for k above, we get:

t1/2 = ln(1/2) / (-0.0117) ≈ 59.1 hours

Therefore, the half-life of the radioactive substance is approximately 59.1 hours.

Volume helps describe the amount of space that a shape takes up.

Volume of a Sphere

Volume describes the 3-dimensional size of a shape. Since volume is a 3-D measurement, the units should be cubed; this explains why the answer is given in feet cubed. In order to find the volume, we need to use the radius. The radius of a sphere is the distance from the center to the outside. In this case, we are told that the radius is 9 ft.

Volume Formula

Every regular shape has its own volume formula. For a sphere, the formula is:

So, to find the volume, all we need to do is plug in the radius. For this sphere, r = 9.

When using 3 for pi, the volume of the sphere is 2916 ft³.

The answer is:

g(x + 1) = 6x + 1

g(4x) = 24x -5

Work/explanation:

To evaluate, I plug in x + 1 into the function:

\(\sf{g(x)=6x-5}\)

\(\sf{g(x+1)=6(x+1)-5}\)

Simplify

\(\sf{g(x+1)=6x+6-5}\)

\(\sf{g(x+1)=6x+1}\)

Do the same thing with g(4x)

\(\sf{g(4x)=6(4x)-5}\)

\(\sf{g(4x)=24x-5}\)

Answer:

The average rate of change is 2.

Step-by-step explanation:

We are given the function:

\(g(x)=-x^2+x+5\)

And we want to find the average rate of change over the interval:

\(-4\leq x\leq 3\)

The average rate of change is synonymous with the slope. So, we will evaluate the function at its endpoints and find the slope between them.

Our first endpoint is given by:

\(g(-4)=-(-4)^2+(-4)+5=-15\)

And our second endpoint is given by:

\(g(3)=-(3)^2+(3)+5=-1\)

This gives us two points (-4, -15) and (3, -1). The average rate of change will be the slope between them. Thus:

\(\displaystyle ARC=\frac{-1-(-15)}{3-(-4)}=\frac{14}{7}=2\)

The average rate of change is 2.

What is basic arithmetic operations?

Basic arithmetic operations are the foundation of mathematics and include addition, subtraction, multiplication, and division. These operations are used to perform mathematical calculations and are necessary for solving a wide range of problems, from simple arithmetic problems to more complex mathematical equations.

The child has $9.30 and spends $0.13 on a snow cone, so their piggy bank balance becomes $9.30 - $0.13 = $9.17.

After finding $0.75 to put in the piggy bank, the child now has $9.17 + $0.75 = $9.92 in their piggy bank.

Evaluate the difference of 37 and 5

32 / x = x / 5

Cross multiply the equation

x × x = 32 × 5

So, we have

x² = 160

Answer:

r=144

Step-by-step explanation:

Cross multiply:

12 * 60 = r * 5

Simplifying

12 * 60 = r * 5

Multiply 12 * 60

720 = r * 5

Reorder the terms for easier multiplication:

720 = 5r

Solving

720 = 5r

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-5r' to each side of the equation.

720 + -5r = 5r + -5r

Combine like terms: 5r + -5r = 0

720 + -5r = 0

Add '-720' to each side of the equation.

720 + -720 + -5r = 0 + -720

Combine like terms: 720 + -720 = 0

0 + -5r = 0 + -720

-5r = 0 + -720

Combine like terms: 0 + -720 = -720

-5r = -720

Divide each side by '-5'.

r = 144

Simplifying

r = 144

Answer:

r=144

Step-by-step explanation:

We need to find r. To do that me must make the top numbers the same.

We'll multiply

\( \frac{12}{r} \times \frac{5}{5 } = \frac{60}{5r} \)

\( \frac{5}{60} \times \frac{12}{12} = \frac{60}{720} \)

Since the top numbers are equal that means the bottoms are too.

So we can create the equation:

\(5r = 720\)

Divide each side by 5

r=144
