Answer:

x ≈ 2.76

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan78° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{13}{x}[/tex] ( multiply both sides by x )

x × tan78° = 13 ( divide both sides by tan78° )

x = [tex]\frac{13}{tan78}[/tex] ≈ 2.76 ( to 2 dec. places )

The formula of volume of a cylinder is given as

[tex]v=\pi r^2 h[/tex]

Let's substitute the values and solve

[tex]v = \pi r^2 h\\\\r = d/2\\d = 20\\r = 20/2 = 10cm\\v = 3.14 * 10^2 * 66\\v = 20724cm^3[/tex]

The volume of a cone is given as

[tex]v = 1/3 \pi r^2 h\\v = 1/3 * 3.14 * 10^2 * 66\\v = 6908cm^3[/tex]

The space remaining from creating the cone out of the cylinder is

[tex]20724 - 6908 = 13816cm^3[/tex]

There would be 22 red chips in the bucket containing 66 total chips.

An equation is an expression that shows the relationship between two or more variables and numbers.

Let us assume the ratio of red chips to blue chips is 1:2.

Hence, if there 44 blue chips in the bucket:

(2/3) * total chips = 44

Total chips = 66

Number of red chips = (1/3) * 66 = 22

There would be 22 red chips in the bucket containing 66 total chips.

  4x^2 +12x +44 remainder 161x +84

Step-by-step explanation:

At each step, the quotient term is the ratio of the leading dividend term to the leading divisor term. The first quotient term, for example, is ...

  (4x^4)/(x^2) = 4x^2

The quotient term found this way is multiplied by the divisor and subtracted from the dividend. The difference is the new dividend and the process repeats.

You're done when the degree of the dividend is less than the degree of the divisor. This remainder can be expressed as a fraction with the divisor as the denominator.

2 1/4 - 2/3 = x

9/4 - 2/3 = x

Answer:

360 yd^3

Step-by-step explanation:

volume of hexagonal pyramid = √3/2 * s^2 * h

s = side

here side is not given. but base area is given

area of hexagon = 3√3/2 a^2

45 = 3√3/2 s^2

s^2 = 30√3 yd^2

volume = √3/2 * 30√3 *8

= 30 * 3 * 4= 360 yd^3

The computation of the ratio shows that 45 lemons are needed to make 30 cups of lemonade.

From the complete information, it should be noted that 12 lemons are required to make 8 cups of lemonade.

Therefore, the ratio in this scenario is 12/8 = 3:2. Therefore, when there are 30 cups, the number of lemons needed will be:

= 30 × 3/2

= 45

In conclusion, 45 lemons are needed to make 30 cups of lemonade.

Answer:

I'm pretty sure,

1. Is a Trapezoid

2. Is a Rhombus

Step-by-step explanation:

Look at a picture of them,

1. A trapezoid has equal length diagonals, but because of the outer legs? if you want to call them that, they're at an angle, same with its vertices, so, the angles at which they bisect are not right angles.

2. A Rhombus, has diagonals that are not the same length, one is longer than the other. Therefore, that solves the first part of the question. And when they bisect, they bisect at right angles because the side lengths of a Rhombus are congruent.

Step-by-step explanation:

Therefore, the probability of picking a black sock is:

P(black) = 6/24

As the sock is NOT replaced, we now have one less black sock:

So the probability of picking a white sock:

P(white) = 10/23

As the sock is NOT replaced, we now have one less black sock and one less white sock:

So the probability of picking a blue sock:

P(blue) = 8/22

Therefore, P(black) and P(white) and P(blue)  is:

6/24 x 10/23 x 8/22 = 480/12144 = 10/253 = 0.03952... = 3.95%

Steven earned $820 more in interest in his account than Evan.

Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter. The compound interest earned is given by the formula,

[tex]A_1 = P(1+\dfrac{r}{100})^n - P[/tex]

In order to compare the two of the given investment, we need to find the interest in each of the investments.

For the investment made by Steven of $20,000 at 3% interest compounded annually for 10 years. The interest that Steven made is,

[tex]A_1 = P(1+\dfrac{r}{100})^n - P\\\\\\A_1 = 20,00(1+0.03)^{10}-20,000\\\\\\A_1 = \$6,878.33[/tex]

For the investment made by Evan of $10,000 at 7% interest compounded annually for 7 years. The interest that Evan made is,

[tex]A_2 = P(1+\dfrac{r}{100})^n - P\\\\\\A_2 = 10,00(1+0.07)^{7}-10,000\\\\\\A_2 = \$6,057.82[/tex]

Now, if we find the difference in the interest earned by the two of the given person.

The difference in the interest earned

= Interest earned by Steven - Interest earned by Evan

= $6878.33 - $6,057.82

= $820.52 ≈ $820

Hence, Steven earned $820 more in interest in his account than Evan.
