Answer:

Surface Area = 1.92m^2

Step-by-step explanation:

r1 & h1= big cylinder

r2 & h2= small cylinder

SA= 2π(r1xh1) + 2π(r2xh2) + [πr2^2 - πr1^2]

SA= 2π(25)(90) + 2π (15)(40) + [π(25)^2 - π(15)^2]

SA= 14137.17cm^2 + 3769.91cm^2 + [1963.50 - 706.86]

SA=  14137.17cm^2 + 3769.91cm^2 + 1256.64cm^2

SA= 19163.71cm^2

Conversion:

1963.71cm^2 x 1m^2/10000cm^2=1.92m^2

Answer: 1.92m^2

Answer:

"y equals one-half times x" shows a proportional relationship.

The data supports the scientists' claim because, as the population grows, the amount of water used will most likely increase, which would leave not enough water for the city's population.

Population increase can have a significant effect on water usage. As the population grows, the demand for water also increases, which can put pressure on water resources and lead to water scarcity, especially in areas where water resources are already limited.

The increase in population also leads to an increase in the number of households and industries, which means more water is required for domestic and industrial purposes. Additionally, the increase in urbanization and changes in lifestyle patterns can lead to an increase in per capita water usage, further exacerbating the demand for water.

Answer:

[tex]\boxed{C) \ 10}[/tex]

Step-by-step explanation:

You need to solve for x.

[tex]\frac{4}{3}=\frac{x+10}{15}[/tex]

An equation can be thought of as a balance scale, so we must do the same operation on both sides in order to maintain equality.

Multiply by 15 on both sides:

[tex]\frac{4}{3} (15) =\frac{x+10}{15} (15)\\\\\frac{4(15)}{3} =\frac{(x+10)\not{15}}{\not{15}}\\\\20=x+10[/tex]

Finally, subtract 10 on both sides.

[tex]20-10=x+10-10\\10=x \implies x=10[/tex]

Therefore, the correct answer is option C.

Answer:

The surface area of each half has increased by 60 cm², which is a percentage increase of 31.6% (nearest tenth).

Step-by-step explanation:

The area of a rectangle is the product of its width and length.

If the object is cut in half along the blue line, each piece will increase its surface area by the area of a rectangle that is 6 cm wide and 10 cm long:

[tex]\implies 6 \cdot 10=60\; \sf cm^2[/tex]

Therefore, the surface area of each piece will increase by 60 cm².

If you want to know the increase as a percentage, we first need to calculate the total surface area of the given object by summing the areas of each side.

[tex]\begin{aligned}\implies \textsf{Total\;S.A.}&=(10\cdot 6)+(4 \cdot 6)+4(5\cdot 6)+2(3\cdot 6)+2(10\cdot 5+4 \cdot 5)\\&=60+24+4(30)+2(18)+2(50+20)\\&=60+24+120+36+2(70)\\&=60+24+120+36+140\\&=380\;\sf cm^2\end{aligned}[/tex]

If the total surface area of the object is 380 cm², then the surface area of each half before the object was cut in half is 190 cm².

As we have already determined, the surface area of each half after the object is cut in half increases by 60 cm².  Therefore, the total surface area of each piece after the object has been cut in half is:

[tex]\implies 190 + 60 = 250 \; \sf cm^2[/tex]

To calculate how much the surface area of each half has increased, use the percentage increase formula.

[tex]\begin{aligned}\textsf{Percentage increase}&=\sf \dfrac{final\;value-initial\;value}{initial\;value}\\\\&=\dfrac{250-190}{190}\\\\&=0.315789...\\\\&=31.6 \%\; \sf (nearest\;tenth)\end{aligned}[/tex]

Therefore, the surface area of each half has increased by 60 cm², which is a percentage increase of 31.6% (nearest tenth).

The time needed for the rocket to be 30 feet of the ground is given as follows:

t = 9.6 seconds.

The quadratic function giving the rocket's height after t seconds is given as follows:

h(t) = -16t² + 150t + 70.

The rocket will be 30 feet of the ground when:

h(t) = 30.

Hence:

-16t² + 150t + 70 = 30

16t² - 150t - 40 = 0.

The coefficients of the quadratic function are given as follows:

a = 16, b = -150, c = -40.

Time is a positive measure, hence, using a quadratic function calculator, the positive root is given as follows:

t = 9.6 seconds.

To find the least common denominator (LCD) of 3/8 and 8/5, we can use the method of prime factorization.

Prime factorization of 8: 2 x 2 x 2

Prime factorization of 5: 5

To get the LCD, we need to include all the prime factors from both denominators, including duplicates:

LCD = 2 x 2 x 2 x 5 = 40

Now we need to convert both fractions so that they have a denominator of 40:

3/8 x 5/5 = 15/40

8/5 x 8/8 = 64/40

Now both fractions have a denominator of 40, and we can compare them more easily. The two fractions are:

15/40 and 64/40

So the LCD of 3/8 and 8/5 is 40.

Answer:

Equation: m=21(p)

Difference: $5

Step-by-step explanation:

To solve this, we first need to figure out an equation for Company R.

We know that Company S's equation is m=26(p). this means that the amount reimbursed is 26 times the amount of aluminum returned.

210/10=21

Company R's equation is m=21(p). We know this because throughout the table, the amount reimbursed is always 21 times more than the amount of aluminum returned.

Now that we have two equations, we can solve. 26-21=5.

Therefore, the difference between the amount reimbursed per pound is $5. (As long as there is not another variable, this should be the answer for part b)

Where

Here we are given the following

Plugging these values into the formula we acquire:

V = π(4)²12

==> evaluate exponent

V = π(16)12
