When laid flat, a round parachute has a radius of 6 meters. What is the parachute's diameter?

Answer:

7

Step-by-step explanation:

Answer: x=32

Step-by-step explanation:

The angles in a triangle add up to 180 degrees.

Since we know a=10 the other two angles must add up to 170 degrees.

[tex]2x+3x=170[/tex]

We can now solve for x

[tex]2x+3x=170\\5x=170\\\frac{5x}{5} =\frac{170}{5}\\x=34[/tex]

We can sub in x to both angles to see if they angles add up to 180

[tex]2(34)+3(34)+10=180\\68+102+10=180\\180=180[/tex]

Answer:

6.3

Step-by-step explanation:

[tex]6^{2} + 2^{2} = x^{2}[/tex]

40 = [tex]x^{2}[/tex]

[tex]\sqrt{40} = \sqrt{x^{2} }[/tex]

x = 6.3

Answer:

6.3

Step-by-step explanation:

Pythagoras' Theorem (or Pythagorean Theorem) states a²+b²=c², where c is the hypotenuse.

We can use this equation and swap a and b for 6 and 2. This gives 6²+2²=c², which can be expanded to 36+4=c², and further c²=40.

To work out c, we need to square root both sides, leaving c=6.3245553203367586639977870888654, which rounded to 1 decimal place (nearest tenth) is 6.3.

A. D(t) = -25t + 160

this is the correct answer because if you substitute 3 you get 85

Answer:

first option is correct

Step-by-step explanation:

3x+12+x=180 degree (being linear pair)

4x+12=180

4x=180-12

x=168/4

x=42

Answer:

Answer:

27.3 dollars

Step-by-step explanation:

Answer:

6 hours.

Step-by-step explanation:

Here's my work.

Chang only wanted to spend $44, and the boat costs $8/hr. So, the variable would only be 8t, and you would put 44 on the other side.

Then, you'd put -4 on the side with 8t, because you can take off $4.

So, the setup would be;

44 = 8t - 4.

Answer:

Rotation

Step-by-step explanation:

It's kind of in the statement, but because the triangle is being rotated, that transformation is called a rotation.

Answer:

(a) -12

(b) 37

(c) -840

Step-by-step explanation:

We simply have to plug in the values for each expression.

2 + -3(3) - 5 = 2 + -9 - 5 = -7 - 5 = -12

5(2) - 4(-3) + 3(5) = 10 - -12 + 15 = 10 + 12 + 15 = 22 + 15 = 37

7(2^3)(-3)(5) = 7(8)(-15) = 56(-15) = -840

Answer:

Answer:

[tex]y=120 * 1.1^x[/tex] --- function

The monthly rate is 10%

Step-by-step explanation:

Given

Let

[tex]x \to months[/tex]

[tex]y \to mice[/tex]

So, we have:

[tex](x_1,y_1) = (0,120)[/tex] --- Monday

[tex](x_2,y_2) = (1,132)[/tex] --- One month later

Required

The function

The function is represented as:

[tex]y=ab^x[/tex]

In [tex](x_1,y_1) = (0,120)[/tex], we have:

[tex]120 = a * b^0[/tex]

[tex]120 = a * 1[/tex]

[tex]120 = a[/tex]

[tex]a=120[/tex]

In [tex](x_2,y_2) = (1,132)[/tex], we have:

[tex]132 = a * b^1[/tex]

[tex]132 = a * b[/tex]

Substitute: [tex]a=120[/tex]

[tex]132 = 120 * b[/tex]

Solve for b

[tex]b = \frac{132}{120}[/tex]

[tex]b = 1.1[/tex]

So, the function is:

[tex]y=ab^x[/tex]

[tex]y=120 * 1.1^x[/tex]

To calculate the monthly rate (r), we have:

[tex]y =a(1 + r)^x[/tex]

Compare to: [tex]y =ab^x[/tex]

[tex]1 + r = b[/tex]

Make r the subject

[tex]r = b-1[/tex]

Substitute [tex]b = 1.1[/tex]

[tex]r = 1.1-1[/tex]

[tex]r = 0.1[/tex]

Express as percentage

[tex]r = 0.1*100\%[/tex]

[tex]r = 10\%[/tex]

Answer:

Step-by-step explanation:

Given expression is,

[tex]\lim_{m \to \infty} \frac{4m^2-6m+1}{3m^2+5m+7}[/tex]

By dividing denominator and numerator of the given fraction by m²,

[tex]\lim_{m \to \infty} \frac{\frac{4m^2-6m+1}{m^2} }{\frac{3m^2+5m+7}{m^2} }[/tex]

= [tex]\lim_{m \to \infty} \frac{4-\frac{6}{m} +\frac{1}{m^2} }{3+\frac{5}{m} +\frac{7}{m^2} }[/tex]

We know that [tex]\lim_{n \to \infty} \frac{1}{n}=0[/tex]

[tex]\lim_{m \to \infty} \frac{4-\frac{6}{m} +\frac{1}{m^2} }{3+\frac{5}{m} +\frac{7}{m^2} }=\frac{4-0+0}{3+0+0}[/tex]

                            [tex]=\frac{4}{3}[/tex]

Therefore, We can evaluate the limit of the expression by substituting ∞ in for m.

Answer:

B

Answer:

-11xy

Step-by-step explanation:

-14xy -(-3xy)

multiply the bract first - sign * minus sign is plus sign

-14xy+3xy

since they are like terms u can subtract them.u should subtract them because minus and plus means subtract and we should put minus sign in front of the answer because 14 is the highest number and it's sign is negative .

-11xy

Answer:

58

Step-by-step explanation:

a = 27, b = -10 and c = 40

= a - (6 - c) + (a - b) - C

= 27 - (6 - 40) + (27 - (-10)) - 40

= 27 - (-34) + (37) - 40

= 27 + 34 + 37 - 40

= 58

[tex]\huge\textsf{Hey there!}[/tex]

[tex]\large\textsf{a - (6 - c) + (a - b) - c}[/tex]

[tex]\large\textsf{= 27 - (6 - 40) + (27 - (-10)) - 40}[/tex]

[tex]\large\textsf{6 - 40 = \bf -34}[/tex]

[tex]\large\textsf{= 27 - (-34) + (27 - (-10)) - 40}[/tex]

[tex]\large\textsf{= 27 + 34 + 27 + 10 - 40}[/tex]

[tex]\large\textsf{27 + 34 = \bf 61}[/tex]

[tex]\large\textsf{= 61 + 27 + 10 - 40}[/tex]

[tex]\large\textsf{61 + 27 = \bf 88}[/tex]

[tex]\large\textsf{88 + 10 - 40}[/tex]

[tex]\large\textsf{88 + 10 = \bf 98}[/tex]

[tex]\large\textsf{98 - 40}[/tex]

Given:

The equation is:

[tex]efg-h=i[/tex]

To find:

The value of f.

Solution:

We have,

[tex]efg-h=i[/tex]

We need to isolate f to find the value of f.

Adding h on both sides, we get

[tex]efg-h+h=i+h[/tex]

[tex]efg=i+h[/tex]

Dividing both sides by [tex]eg[/tex], we get

[tex]\dfrac{efg}{eg}=\dfrac{i+h}{eg}[/tex]

[tex]f=\dfrac{i+h}{eg}[/tex]

Therefore, the value of f is [tex]f=\dfrac{i+h}{eg}[/tex].
