What is the shape of the cross section perpendicular to the base of the cone

Answer:

It is actually C, just took it and D was wrong

Step-by-step explanation:

Answer:

Cora

Daniel

Daniel

Step-by-step explanation:

Forming equation for Daniel's saving from the plot:

Slope, m :

m = y2 - y1 / x2 - x1

m = (300 - 150) / (3 - 1)

m = 150 /2

m = 75

Intercept, c ; value of y when, x = 0

c = 75

Daniel's equation :

y = 75x + 75

Initial amout is described by intercept

Cora's intercept = 100

Daniel's intercept = 75

Rate is described by the slope

Daniel = 75

Cora = 65

So, Daniel is saving at a faster rate ; 75 to Cora's 65

Amount after 6 months :

After 6 months

y = 75*6 + 75 = $525

Cora:

y = 65x + 100

y = 65*6 + 100 = $490

Answer:

1. 2

2. 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Step-by-step explanation:

1. |4−2| (simplified)

= |2|

=2

2. 2a^2 = 5.2

(22)(1.3)

=(4)(1.3)

=5.2

(2.6 - (2*1.3))=

5.2 - (2.6 - 2.6) = 5.2

3. (c * 2) - 3= a

4. ($85 + $35 * h)

Answer:

It is -0.465 when you add it to the nearest thousandth

Step-by-step explanation:

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

Explanation:

Your teacher wants you to find the slope

m = slope

m = (y2-y1)/(x2-x1)

m = (-1-2)/(3-9)

m = -3/(-6)

m = 1/2

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

Extra info:

We can think of the slope as

slope = rise/run

and furthermore,

Essentially we subtract the corresponding y coordinates together, subtract the x together (in the same order as the y values), then divide the differences.

Answer:

The ordered pair (-2,5) reflected over the y-axis is (2,5)

Answer:

A

Step-by-step explanation:

correct on edge

Answer:

A) [-1,1]

Step-by-step explanation:

The function of y=cos⁻¹(x) has a domain of [-1,1] and a range of [0,π]. Observe the graph.

A triangle has a total degrees of 180, so you add 55 and 53 to get 108

then you subtract that from 180 to get 72. 72 is your answer

Answer:

72 degrees

Step-by-step explanation:

First of all, you should know that each triangle equals to 180 degrees. So just add 55 + 53 which equals 108. Then you just subtract 108 from 180 (180-108) which equals to 72 degrees.

Therefore, the third missing angle measure is 72 degrees.

f(-7) = 18

Step-by-step explanation:

Add AbS in calculator

14+4 = 18

Answer:

45 individuales y 75 dobles.

Step-by-step explanation:

Para saber esto, debemos plantearlo por medio de un sistema de ecuaciones. En este caso las incógnitas serían el tipo de habitación, es decir, una será la habitación doble, y la otra la individual.

X: habitaciones individuales

Y: habitaciones dobles

Sabiendo eso, sabemos que sumando ambos tipos de habitaciones, dan el total de 120, por tanto, la primera ecuación será:

x + y = 120  (1)

Para la segunda ecuación, sabemos que hay 195 camas en total, que deben distribuirse en los dos tipos de habitaciones, en una habitación doble van 2 camas, mientras que en una individual va 1, por tanto:

x + 2y = 195   (2)

Ahora que tenemos las dos ecuaciones, solo resta resolverlo por alguno de los métodos conocidos de sistema de ecuaciones. En este caso, como las ecuaciones son sencillas podemos usar el método de reducción.

Answer:

804.25

Step-by-step explanation:

The area of a circle = pi(r)^2

Given the diameter, we can find the radius by dividing the diameter in half.

r=16

pi(16)^2 = 804.25

Answer:

803.84 OR 256 pi

Step-by-step explanation:

Ok!

Step 1:

The area of a circle is Pir^2. (Sorry it’s pi r squared, I don’t have the pi symbol or the exponent function on my iPad.)

R is radius. Remember, radius is half the diameter.

32/2=16.

Step 2:

Do 16^2.

You should get 256.

Step 3:

Multiply 256 by Pi. Pi is 3.14. You should get 803.84.

Step 4:

803.84 should be the answer, I THINK (not sure) you can also write your answer as 256 pi. Depends on what your teacher wants. Hope this helps! Next time you can search up how to find the area of a circle, there are lots are tutorials!

Answer:

diameter=14

radius =14/2=7

area =πr²

hope it helps

Step-by-step explanation:

Area of circle = 2π r²

diameter is 14 cm so radius will be 7 cm

= 2 × 22/7 × 7 × 7

= 44 × 7

= 308 cm²

Answer:

G: 135

Step-by-step explanation:

The plot has a trend of increasing every year by some number so in year 1980 the participants should be more than 120 (because 1972 has 120 people) to follow the given trend. Thus, best answer is G = 135 countries.

Answer:

The smallest number is 7

Step-by-step explanation:

Using simultaneous equation;

x+y = 18.....(1)

4x-y = 17.....(2)

from equation (1)..

x+y = 18

y = 18-x...(3)

substitute y into equation (2)

4x-y = 17

4x-(18-x) = 17

4x-18+x = 17

4x+x = 17+18

5x = 35

x = 35÷5

x = 7

substitute x into equation (3)

y = 18-x

y = 18-7

y = 11

Therefore; x=7

y=11

11+7=18

(4×7)-11=17

the smallest number is 7
