In a 30-60-90 triangle what is the measure of the hypotenuse if the shorter leg measures 10cm?

Answer:

A. Yes they do. Both equations have their opposing set of y-intercept. Where equation one has a y-intercept of +7, and equation two, +7.

B. No they do not. Equation one has a slope of +3, while equation 2 has a slope of -4.

C. Yes they do. Equation one represents that of a positive increasing graph, while equation two the opposite, decreasing.

Step-by-step explanation:

You can use the slope formula to identify and graph each equation simply by using y = mx + b. Where y is the the y coordinate, x is the x coordinate, m is the slope, and b is the y-intercept. With this you can start plotting by marking the y-intercept by putting the x as zero and seeing what number you get. In this case, 3x0-7 = -7. Meaning that would be the y-intercept. For the slope, depending on what the x coordinate is, that's how much the graph will increase or decrease whenever the x coordinate changes. Say the x coordinate is 1, so 3x1-7 = 3-7 = -4. Meaning your coordinate would be (1, -4) where you can keep doing this formula on and on to find the y coordinate for what x coordinate you want to find, or make it easier to graph with a ruler on paper once you have enough points.

Answer:

Answer = 5.5

Step-by-step explanation:

The formula for finding the surface area of a cube is SA = 6(s^2) where s = sides. Since we know the surface area we plug it in for SA. So,

181.5 = 6*s^2

Now we divide 6 by both sides to get

30.25 = s^2

Now we have to find the square root of both sides to get

5.5 = s

Step-by-step explanation:

The linear function that you could use to find the number of weeks it would take to reach your goal is:

35n + 100 = 800.

A linear function is modeled by:

y = mx + b

In which:

From the table, we have that:

Hence the balance after n weeks is given by:

B(n) = 100 + 35n.

You will have $800 when B(n) = 800, hence the equation is:

35n + 100 = 800.

The value of x such that the hcf is 26 and the l.c.m is 1092 is 156

The numbers are given as:

182 and x

The HCF and LCM are given as:

HCF = 26

LCM = 1092

As a general rule;

The product of LCM and HCF of x and y equals the product of x and y

So, we have:

182 * x = 26 * 1092

Divide both sides by 182

x = 156

Hence, the value of x is 156

Using proportions, it is found that the correct statement is given by:

C There were 56 more people who ate a turkey sandwich than ate a chicken sandwich.

A proportion is a fraction of a total amount.

In this problem, one third out of 840 people ate Turkey Sandwich, hence the number is given by:

nT = 840/3 = 280.

One sixth ate Vegetarian Sandwich, hence the number is given by:

nV = 840/6 = 140.

4/15 ate Chicken Sandwich, hence the number is given by:

nC = 4 x 840/15 = 224.

7/30 ate Salad, hence the number is given by:

nS = 7 x 840/30 = 196.

Answer:

D.  The graph of g is the graph of f shifted 2 units down.

Step-by-step explanation:

Transformations

f(x) - a :  vertical shift of "a" units down

f(x) + a : vertical shift of "a" units up

f(x - a)  : horizontal shift of "a" units to the right

f(x + a) : horizontal shift of "a" units to the left

If  g(x) = f(x) - 2

Then g(x) is f(x) shifted 2 units down.

1500 mg is the least mass

Step-by-step explanation:

Lets convert them all to the same mass unit,

1500 mg to grams: 1500 mg / 1000 = 1.5 grams

13.2 kg to grams: 13.2 kg x 1000 = 13,200 grams

30000 cg to grams: 30,000 cg / 100 = 300 grams

7428g no conversion needed!

1.5 grams, 13,200 grams, 300 grams, 7,428 grams

Answer:

the answer simplified is 24

Step-by-step explanation:

======================================================

Explanation:

There are at least three ways to solve this.

----------------------------------------------

Method 1:

We could graph y = (x-2)(x+10) using a tool like Desmos. Graph y = 13 as well which is a horizontal line.

Check out the screenshot shown below.

The parabola in red and the horizontal line in blue intersect at the locations (-11, 13) and (3, 13)

We only focus on the x coordinates of the intersection points.

Therefore, the two solutions are x = -11 and x = 3

The order of the solutions doesn't matter.

----------------------------------------------

Method 2:

Expand things out and get everything to one side

(x-2)(x+10) = 13

x^2 + 10x - 2x - 20 = 13

x^2 + 8x - 20 - 13 = 0

x^2 + 8x - 33 = 0

From here we can use the quadratic formula

[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-8\pm\sqrt{(8)^2-4(1)(-33)}}{2(1)}\\\\x = \frac{-8\pm\sqrt{64+132}}{2}\\\\x = \frac{-8\pm\sqrt{196}}{2}\\\\x = \frac{-8\pm14}{2}\\\\x = \frac{-8+14}{2} \ \text{ or } \ x = \frac{-8-14}{2}\\\\x = \frac{6}{2} \ \text{ or } \ x = \frac{-22}{2}\\\\x = 3 \ \text{ or } \ x = -11\\\\[/tex]

----------------------------------------------

Method 3:

Instead of using the quadratic formula, we could factor.

To factor x^2+8x-33, we need to find two numbers that

Through trial and error, you should get 11 and -3

So,

x^2+8x-33 = 0

(x+11)(x-3) = 0

x+11 = 0 or x-3 = 0

x = -11 or x = 3

It deals with the size of geometry, region, and density of the different forms both 2D and 3D.

The volume of a right cone is 3975π cubic units.

If its radius measures 15 units.

Then the height of the cone will be

The volume of the cone is given as

Volume = 1/3 x π x r² x h
