Answer:

80 inches

Step-by-step explanation:

8*10=80

Answer:

80 in.

Step-by-step explanation:

So we know that 1/8 is 10 in.

So to get 8/8 (Original length), we need to multiply 10 by 8, because 8 is the denominator.

10 in * 8 = 80 in.

Answer:

The volume of oblique cylinders is the same volume as a right cylinder of the same radius and height. The height of cylinder must be the perpendicular height, but as long as the radius and height are the same the volume does not change, which is why the same formula can be used for both oblique and right cylinder.

For skewed and right prism, base length and height does not change, volume for both is calculated by area times height.

Answer:

7.85 m

Step-by-step explanation:

Circumference is 2πr.

The radius (r) is half of the diameter, but multiplying r by 2 is the same as just using the diameter in this formula, so:

2.5π

When you multiply you get 7.85 to the nearest hundredth.

Answer:

147

Step-by-step explanation:

The n th term of an arithmetic sequence is

[tex]a_{n}[/tex] = a + (n - 1)d

where a is the first term and d the common difference

here a = 3 and d = 9 - 3 = 15 - 9 = 6, hence

[tex]a_{25}[/tex] = 3 + (24 × 6) = 3 + 144 = 147

Step-by-step explanation:

209 seats were used by men and boys. i took 45% of 380 which = 171. I subtracted that by 380 which = 209.

Answer with Step-by-step explanation:

0.45 of the total seats were used by women and girls.

i.e. Remaining 0.55(1-0.45) of the total seats were used by men and boys.

Seats used by men and boys=55% of 380

                                               [tex]= \dfrac{55}{100}\times 380\\\\ =209[/tex]

Hence, Seats used by men and boys is:

209

and the fraction of total number of seats used by men and boys(0.55) is greater than that of total seats used by women and girls(0.45).

Answer:

The perimeter is 22.

Step-by-step explanation:

The perimeter formula (it sometimes varies) is 2(b+h)

b being base (in this example, 6)

h being height (in this example, 5)

So now, with substitution, we are left with:

2(6+5)

Which simplifies down to:

2(11)

22

The answer is:

The area that the want to cover with new grass will be:

[tex]Area_{grass}=8x^{2} -12x-22[/tex]

If we want to calculate what is the ara of the region of the backyard that they want to cover with new grass, we need to calculate the area of the backyard, calculate the area of the swimming pool and its patio, and the last step is to subtract the area of the swimming pool and its patio to the total area of the backyard.

So, to calculate the areas, we need to use the following formula:

[tex]Area=Length*Width[/tex]

Also, we need to remember how the distributive property works, since we are going to need it.

We have that:

[tex](a+b)(c+d)=ac+ad+bc+bd[/tex]

We are given the following information:

For the backyard we have:

[tex]Length=3x-2\\Width=3x+1[/tex]

For the swimming pool and its patio:

Since there it's not mentioned, let be the first expression the length, and the second one, the width.

[tex]Length=x+4\\Width=x+5[/tex]

Then, calculating we have:

Backyard:

[tex]Area_{backyard}=(3x-2)*(3x+1)=9x^{2}+3x-6x-2=9x^{2}-3x-2[/tex]

Swimming pool and patio:

[tex]Area_{swimmingpool}=(x+4)*(x+5)=x^{2}+5x+4x+20=x^{2}+9x+20[/tex]

Now, calculating the area that they want to cover with new grass, we have:

[tex]Area_{grass}=Area_{backyard}-Area_{swimmingPool}\\\\Area_{grass}=(9x^{2}-3x-2)-(x^{2}+9x+20)\\\\Area_{grass}=9x^{2} -x^{2} -3x-9x-2-20\\\\Area_{grass}=8x^{2} -12x-22[/tex]

Hence, we have that the area that the want to cover with new grass will be:

[tex]Area_{grass}=8x^{2} -12x-22[/tex]

I think the answer is x=-4,x=+6

The values of the x are +6 and -4. The values of the x are obtained by the factorization method.

They are mathematical formulas containing variables raised by non-negative integers, coefficient, and constants involving only addition, subtraction, multiplication, and non-negative exponentiation of variables.

The given expression is;

x²-2x-24= 0

By factorization;

x²-6x+4x-24=0

After taking common terms, we get ;

x²-6x+4x-24=0

x(x-6)+4(x-6)=0

(x+4)(x-6)=0

The value of the x is found as;

x-4=0

x=-4

x-6=0

x=+6

Hence, the values of the x are +6 and -4.

Answer:

[tex] \frac{1}{2} \times 21.6 \times 5.9 = 63.72[/tex]

The area of this triangle is 63.72 square feet.

The distance between two points on a number line is found using the absolute value of their difference. For instance, the distance between 2 and 14 is 12 units, and the distance between -10 and 8 is 18 units.

The concept of absolute value is crucial when determining the distance between two points on a number line. This distance is represented by the difference in their values, disregarding which one is larger or whether they are positive or negative.

The expression for the distance is |2 - 14|. Evaluating this, we find |2 - 14| = |-12| = 12. Therefore, the distance between the numbers 2 and 14 on the number line is 12 units.

The expression for the distance is |-10 - 8|. Evaluating this, we find |-10 - 8| = |-18| = 18. Therefore, the distance between the numbers -10 and 8 on the number line is 18 units.

Answer:

[tex]r=0.0718[/tex]. The closest value from your given choices is C)r=0.69

Step-by-step explanation:

To solve this we are using the standard exponential growth equation:

[tex]f(t)=A(1+r)^t[/tex]

where

[tex]f(t)[/tex] is the final population after [tex]t[/tex] years

[tex]A[/tex] is the initial population

[tex]r[/tex] is the growth rate in decimal form

[tex]t[/tex] is the time in years

We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so [tex]A=5000[/tex], [tex]f(t)=10000[/tex], and [tex]t=10[/tex].

Let's replace the values and solve for [tex]r[/tex]:

[tex]f(t)=A(1+r)^t[/tex]

[tex]10000=5000(1+r)^{10}[/tex]

Divide both sides by 5000

[tex]\frac{10000}{5000} =(1+r)^{10}[/tex]

[tex]2=(1+r)^{10}[/tex]

Take root of 10 to both sides

[tex]\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}[/tex]

[tex]\sqrt[10]{2} =1+r[/tex]

Subtract 1 from both sides

[tex]\sqrt[10]{2}-1=r[/tex]

[tex]r=\sqrt[10]{2}-1[/tex]

[tex]r=1.0718-1[/tex]

[tex]r=0.0718[/tex]

We can conclude that the growth rate of our exponential equation is [tex]r=0.0718[/tex]. The closest value from your given choices is C)r=0.69

The correct anwser would be 56

The volume of the prism filled with 30 cubes with side lengths of 1/2 unit is 3.75 cubic units.

To calculate the volume of a cube with a side length of 1/2 unit, we use the formula V = s³, where s is the side length of the cube.

For a side length of 1/2 unit, the volume of one cube is V = (1/2)³ cubic units.

Therefore, the volume of one such cube is 1/8 cubic units. If the prism is filled with 30 such cubes, we multiply the volume of one cube by the number of cubes:

Total Volume = Number of Cubes × Volume of One Cube = 30 × 1/8 cubic units = 30/8, which simplifies to 3.75 cubic units.

Answer:

Step-by-step explanation:

For this, both sides added together will need to equal 180°.

So you need to set up an equation: p+28+3p=180

Now, solve for p

p+28+3p=180

    -28 .       -28

p+3p=152

combine p            (the single p counts as 1, so add it to 3p to get 4p)

4p=152

/4 .   /4

p= 38

You get p is equal to 38.

Step-by-step explanation:

Given

pitchers of grape juice=g=4

picthers of orange juice=o=6

Each pitcher contains 64 oz of juice

So in order to calculate, we will calculate the total number of pitchers and then multiply it by 64 to get total oz.

=(6+4)*64

=10*64

=640 oz

We can see that we added count of pitchers and then multiplied the sum by 64.

Answer:

Area of Trapezoid is 88 Units^2

Step-by-step explanation:

Area of trapezoid = (a+b)/2 * h

where a and b are lengths of each base and h is the height of trapezoid.

In the question given:

a= 17 (because a is the upper base and value will be 17)

b= 27 (because b is the lower base and value will be 17+5+5 = 27)

h= 4

Area of trapezoid = (a+b)/2 * h

                             = (17 +27)/ 2 * 4

                             = 22 * 4

                             = 88 Units^2
