x + 2x + 3x = 180°

6x = 180°

Therefore, x = 30°

2 x = 60°

3x = 90°

Hence, it is a right angled triangle.

Answer:

The triangle is right

Step-by-step explanation:

x+2x+3x=180

6x=180

x=30

30-60-90

The largest angle is 90 degrees which means that the triangle is right. (def of right triangle)

Answer:

7900/100*80 = 6320

Step-by-step explanation:

In a crowd of 7,900, there are 1,580 children, representing 20% of the total population.

To find out how many children are in a crowd of 7,900 when the proportion is 20%, you can use the following steps:

1. Calculate the proportion (20%) as a decimal: 20% = 0.20.

2. Multiply the crowd size (7,900) by the proportion (0.20) to find the number of children:

Children = 7,900 * 0.20 = 1,580.

So, in a crowd of 7,900, there are 1,580 children.

This calculation is based on the assumption that the 20% proportion represents the fraction of the crowd that consists of children. If you have additional information about the crowd's composition or the nature of the 20%, such as whether it includes adults or other groups, the calculation may differ.

Zeke can make a profit of $10.80 per share if he sells his stocks now. His broker expects a decline in the future, so selling now would be a good decision.

Zeke's situation pertains to the world of finance and stock investment. He bought 10 shares of a company's stock at $21.20 per share and it's currently priced at $32 per share. By subtracting the buying price from the current price, we can calculate the profit per share which is $10.80.

So, if he sells the stocks now, he will make a profit of $10.80 per share. For 10 shares, that's a total profit of $108 (10 shares * $10.80 per share). If his broker expects a decline in the price, Zeke ideally should sell the shares now to profit before the prices go down.

Generally, the rate of return on a financial investment in a share of stock can be from dividends paid by the firm or as a capital gain achieved by selling the stock for more than you paid. In this case, Zeke's profit would be considered a capital gain.

Answer:

90°

Step-by-step explanation:

supplementary angles, when added = 180°

so if one angle is 90°, then the other angle, its supplement, is 180 - 90 = 90°

Answer:

90°

Step-by-step explanation:

The supplement of an angle is what, when added to it, equals 180°.

So if we have 90°, we would subtract 90° from 180° to get 90°.

The supplement of 90° is 90°.

The complement of 85° is 5°, since they add up to equal 90° a right angle. So the complement of 90° is 0°

Answer:

The answer is A. Hope I helped you! ;)))

Step-by-step explanation:

The triangle is acute and is isosceles.

The correct answer is [tex]$\sqrt{3}$[/tex]. Hence the correct option is d.

To find the value of [tex]$\tan 60^\circ$[/tex] using the unit circle, follow these steps:

Draw the unit circle, which is a circle with a radius of 1 unit centered at the origin (0,0) on the Cartesian coordinate plane.

Identify the point on the unit circle corresponding to [tex]$60^\circ$[/tex]. This point is located in the first quadrant and makes an angle of [tex]$60^\circ$[/tex]with the positive x-axis.

Since the unit circle has a radius of 1, the coordinates of the point corresponding to 60 are:

[tex]$x$-coordinate: $\cos(60^\circ) = \frac{1}{2}$\\$y$-coordinate: $\sin(60^\circ) = \frac{\sqrt{3}}{2}$[/tex]

Now, we'll use the definition of tangent to find [tex]$\tan(60^\circ)$[/tex]:

[tex]$\tan(\theta) = \frac{\sin(\theta)}{\cos(\theta)}$\\Substitute the values of $\sin(60^\circ)$ and $\cos(60^\circ)$ into the formula:$\tan(60^\circ) = \frac{\frac{\sqrt{3}}{2}}{\frac{1}{2}}$[/tex]

Simplify the expression:

[tex]$\tan(60^\circ) = \left(\frac{\sqrt{3}}{2}\right) \cdot \left(\frac{2}{1}\right)$$\tan(60^\circ) = \sqrt{3}$[/tex]

So, the correct answer is [tex]$\sqrt{3}$[/tex]. Hence the correct option is d.

The product will break even when x is greater than or equal to 18 units, i.e., x ≥ 18, as revenue (R) exceeds or equals cost (C) at this production level.

To find the intervals where the product will at least break even, we need to determine the values of x for which the revenue (R) is equal to or greater than the cost (C), i.e., R ≥ C.

Given:

Cost function C(x) = 55x + 450

Revenue function R(x) = 80x

We can set up the inequality:

80x ≥ 55x + 450

To isolate x, we can subtract 55x from both sides:

80x - 55x ≥ 55x - 55x + 450

This simplifies to:

25x ≥ 450

Now, divide both sides by 25 to solve for x:

x ≥ 450 / 25

x ≥ 18

So, the product will break even when x is greater than or equal to 18. This means that for any production level of 18 units or more, the revenue will be equal to or greater than the cost, ensuring that the product is at least breaking even. Therefore, the interval where the product will at least break even is x ≥ 18.

To break even, the revenue (R) must equal the cost (C). Setting the revenue function R = 80x equal to the cost function C = 55x + 450 and solving for x, we find that the product will break even when x >= 18 units, meaning the company will begin to make a profit at any production level greater than 18 units.

To find where the product will at least break even, we need to determine when the total revenue
(R) is greater than or equal to the total cost (C). The cost to produce
x units of wire is given by C = 55x + 450, and the revenue by R = 80x. To break even,
R must be equal to C:

80x = 55x + 450

Solving for x gives us:

80x - 55x = 450

25x = 450

x = 450 / 25

x = 18

Therefore, the product will break even at x = 18 units. For any number x greater than 18, R will be greater than C, which means profits are being made. The interval for breaking even is thus x >= 18.

Final answer:

The constant of variation k is found by substituting the given values into the direct variation equation t = k√s and solving for k, leading to the result k = 32.

Explanation:

We are given that t varies directly as the square root of s, which can be represented as t = k√s, where k is the constant of variation. To find k, we use the provided values: t=64 when s=4. Substituting these values into the equation gives us:

64 = k√4

Since the square root of 4 is 2, we get:

64 = 2k

Dividing both sides by 2, we find that k = 32, which is the constant of variation.

The length of the line segment is 10 units.

Step-by-step explanation:

Let us call the given two points: (x₁, y₁) = (2, -3) and (x₂, y₂) = (8, 5).

The distance between two points, d = [tex]$ \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2} } $[/tex]

Here, [tex]$ (x_1, y_1) = (2, -3) $[/tex] and

[tex]$ (x_2, y_2) = (8, 5) $[/tex]

Therefore, distance, d = [tex]$ \sqrt{(8 - 2)^2 + (5 - (-3))^2 $[/tex]

[tex]$ = \sqrt{6^2 + 8^2} $[/tex]

[tex]$ = \sqrt{36 + 64} $[/tex]

[tex]$ = \sqrt{100} $[/tex]

= 10 units.

Hence, the answer.

Step-by-step explanation:

Let r be the radius of the circle

The area of a circle is  A = pi * r^2

We know the area is 49 pi

pi r^2=49 pi

r^2=49 pi/pi

r^2=49

r=sqrt 49

r=7

The circumference of the circle is calculated as

C = 2pi*r

C = 2 *pi *(7)

C = 14*pi   cm

pi=22/7

C=14*22/7=2.22=44 inches

so,C =44 inches

Answer:

Kiki has 0.03 cents more than Jordan.

Step-by-step explanation:

so first add 2.48 and 1.69= 4.17

Kiki's amount of money= $4.17

Add 3.05 and 1.09= 4.14

Jordan's amount of money= $4.14

subtract 4.17-4.14=0.03

After adding up the amounts for both Kiki and Jordan, it is determined that Kiki has more money by $0.03.

To find out who has more money, Kiki or Jordan, we need to add up the amounts that each person has in their respective locations and then compare the totals. First, let's calculate Kiki's total amount:

Adding these two amounts gives Kiki a total of $4.17.

Now let's calculate Jordan's total amount:

Adding these two amounts gives Jordan a total of $4.14.

By comparing the two totals, we see that Kiki has more money than Jordan. The difference in their amounts is $4.17 (Kiki's total) - $4.14 (Jordan's total) = $0.03. Therefore, Kiki has three cents more than Jordan.

In a complete sentence: Kiki has more money than Jordan by three cents.
