What angles are coterminal to an angle measuring 2π3 or −11π7?

Answer: Solve for a: a = [tex]\frac{8n+1}{n}[/tex]

Solve for n: [tex]n=\frac{1}{a-8}[/tex]

Step-by-step explanation:

solve for n: Move all terms to the left side and set them equal to zero. Then set each factor equal to zero.

solve for a: Divide each term in an = 9 + (n−1) ⋅ 8 by n and simplify.

Answer:

324

Step-by-step explanation:

The missing term in this geometric sequence is the geometric mean of 54 and 1944.

[tex] \sqrt{54 \times 1944} = \sqrt{104976} = 324[/tex]

Answer:

324

Step-by-step explanation:

The formula for the missing term in a geometric sequence is the square root of x times y.

Step-by-step explanation:

for this we need to know the conversion rate between miles and kilometers :

1 mile = 1.60934 km

which means

1 km = 0.621371 miles

so,

70 m/h = 70×1.60934 km/h = 112.6538 km/h

compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.

the difference is

7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h

Answer:

$8927.1

Step-by-step explanation:

printed price is the actual price without including tax price

tax price= 9/100×9810

tax price= 0.09×9810= $882.9

printed price of the camera= 9810-882.9= $8927.1

Answer:

582 ft squared

Step-by-step explanation:

15*9*2 = 270

15*4*2 = 120

6*6*2 = 72

9*4*2 = 72

6*4*2 = 48

270 + 120 + 72 + 72 + 48 = 582

Step-by-step explanation:

The hundredth number in the series as defined in the task content is; 107.

According to the task content;

The first term of the sequence of numbers is; 8 and evidently, the common difference of the sequence is; 9-8 = 1.

On this note it follows that the 100th number is;

T(100th). = 8 + 99(1) = 107.

Answer:

15 answers

Step-by-step explanation:

To solve this question we need to set up an equation.

Let's name the number of incorrect answers x.

We can set up an equation that's essentially:

(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score

When we plug in our numbers and variables it looks like this:

5(3)+(-2x)=-15

Simplify

15-2x=-15

Subtract 15 from both sides

-2x=-30

Divide both sides by -2

x=15

This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

8.5x23+70=265.5

Hence the correct answer is C

Answer:

Will you be my friend? please answer

Step-by-step explanation:

what do you need to find ?

the number of pizzas and calzones they were eating ?

if so :

p = number of pizzas

c = number of calzones

3p + 2c = 18

2p + 5c = 23

let's multiply the first equation by 2 and the second squadron by 3, and then subtract the second from the first :

6p + 4c = 36

- 6p + 15c = 69

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

0 -11c = - 33

c = 3

2p + 5c = 23

2p + 5×3 = 23

2p + 15 = 23

2p = 8

p = 4

so, they were eating 4 pizzas and 3 calzones.

Answer:

where

r radius of semicircle

→ ½ * 22/7 * r² = 35

→ 11/7 * r² = 35

→ r² = 35*7/11

→ r² = 245/11

→ r² = 22.77

→ r = √22.77

→ r = 4.77

Therefore,

Diameter = 2*4.77

= 9.54 cm

Answer and Explanation:

x= 5.04

so, as this is a multiple choice question, the two values are

A - five ones and forty thousands

and

C - (5x1) + (4 x 1/100)

and as they both equal 5.04 (the value of "x"), those two would be the correct answers out of the four options given, hope this helps!!

Answer:

in terms of pi: 112.5pi mm squared

substituting pi for 3.14: 353.25 mm squared

Step-by-step explanation:

Surface area cone equation:

Πr2 + π*r*s

4.5^2 = 20.25pi

400 + 20.25 = 420.25

sqrt(420.25) = 20.5

20.25pi + 92.25pi = 112.5pi

Decay

Step-by-step explanation:

Any "r" value between 0 and 1 indicates an exponential function in decay. The "r" value is the one in the parentheses and raised to the exponent. In this case, the value is 0.91. This number falls within the "r" value boundaries of a decaying exponential function.
