What is the diameter of a circle multiplied by to get the circumference?

A. radius
B. perimeter
C. area
D. pi

Answer:

[tex]\frac{dZ}{dt}[/tex]= [tex]\frac{40}{\sqrt{545} }[/tex] , so the model car is moving away from the fixed point at a rate of approximately 1.7 feet per second.

Step-by-step explanation:

The functions x and y satisfy (x−20)^2+y^2=25 and differentiating gives 2(x−20)dx/dt+2y dy/dt=0. Substituting the three known values and solving for dy/dt yields dy/dt=−32. Since Z=x^2+y^2−−−−−−√, dZ/dt=(2x ^ dx/dt+2y^dy/dt) / 2x2+y2√. Substituting Since Substituting for x, y,[tex]\frac{dx}{dt}[/tex] , and [tex]\frac{dy}{dt}[/tex] gives [tex]\frac{dZ}{dt}[/tex]= [tex]\frac{40}{\sqrt{545} }[/tex] ,

Answer:

1 rice cake has 23.761 calories

Step-by-step explanation:

18 rice cakes weigh a total of 130 g.

There are 329 calories in 100 g of rice cakes.

Step 1

We calculate the number of calories is 18 rice cakes

18 rice cakes = 130g

Hence,

100g = 329 calories

130g = x

Cross Multiply

100g × x = 130g × 329 calories

x = 130g × 329 calories/100g

x = 427.7 calories

Therefore, 18 rice cakes had 427.7 calories

Step 2

How many calories are there in one rice cake?

18 rice cakes = 427.7 calories

1 rice cake = x

Cross Multiply

18 × x = 1 × 427.7

x = 427.7/18

x = 23.761111111 calories

Approximately = 23.761 calories

Therefore, 1 rice cake has 23.761 calories

Answer:

[tex]W \le 6[/tex]

Step-by-step explanation:

Given

[tex]Area = 60ft^2\ (max)[/tex]

[tex]Length = 10ft[/tex]

Required

Represent the width as an inequality

First, we represent the area as an inequality.

[tex]Area = 60ft^2\ (max)[/tex]

max as used above means less than or equal to.

So, we have:

[tex]Area \le 60[/tex]

The area of a rectangle is:

[tex]Area = L * W[/tex]

So, we have:

[tex]L * W \le 60[/tex]

Substitute 10 for L

[tex]10 * W \le 60[/tex]

Divide both sides by 10

[tex]\frac{10 * W}{10} \le \frac{60}{10}[/tex]

[tex]W \le \frac{60}{10}[/tex]

[tex]W \le 6[/tex]

Answer:  the degree will go down 90 degrees

Step-by-step explanation: An obtuse triangle is one that has an angle greater than 90°. An acute triangle is defined as a triangle in which all of the angles are less than 90°.

Answer:

[tex]5y^2 +6 + x\ cm[/tex]

Step-by-step explanation:

The computation of the perimeter of the triangle is shown below:

As we know that

The Perimeter of the triangle is

= one side + second side + third side

[tex]= 3y^2 + 4 + 2y^2 - 5x + 6x + 2\\\\= 5y^2 +6 + x\ cm[/tex]

Hence, the same is relevant

Thats the answer from american school

Step-by-step explanation:

The value of the common length BD would be 8 units aprroximately.

Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.

Given information;

1. Considering line BD as a side of ABD, express its length in terms of variables representing side lengths and angle measures in ABD.

So, We know that

Sin A = BD / AB

Sin A = BD / c

c Sin A = BD

Substitute;

(10) Sin (53.13) = BD

BD = 10 ( 0.79)

BD = 7.99

Therefore, the value of the common length BD would be 8 units aprroximately.

Answer:

Hello im pretty sure that the represents the friend prove me if im wrong

Step-by-step explanation:

Maria and Don has claimed $1839.8 as a medical deduction.

Calculate medical expenses after removing medical insurance expense, that is

20,800 - 60% of 20,800

= 12480

Now, 20,800-12480

=$8,320

Now calculate 10% of gross income

10% of 101,598

= 10/100 × 101,598

= 0.1 × 101,598

= $10,159.8

Now medical deduction = 10% of income - Medical expenses

= 10,159.8-8,320

= $1839.8

Therefore, the medical deduction is $1839.8.

Answer: DC=30.5

Step-by-step explanation:

Use trigonometry to solve this question

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

First Step: find BD

- AB relative to 54° is [hypotenues]

- BD relative to 54° is [opposite]

- Therefore, we need to use O/H, which is Sin

- sin(54°)=O/20=20·sin(54°)=16.2

Second Step: Find DC

- DC relative to 28° is [adjacent]

- BD relative to 28° is [opposite]

- Therefore, we need to use O/A, which is tan

- tan(28°)=16.2/A=16.2/tan(28°)=30.5
