Answer:

x + y + z = 41.5

Step-by-step explanation:

(5x)° = 100°

x = 20

(4y + 10)° + 100° = 180° ⇒ y = [tex]\frac{35}{2}[/tex] = 17.5

(4z² + 16)° + 100° = 180° ⇒ z = 4

x + y + z = 20 + 17.5 + 4 = 41.5

Answer:

0.63 or 63/100

Step-by-step explanation:

Answer:

0.63

Step-by-step explanation:

For this you would want to do the reverse operation. So you see that it is multiplication? You would have to do division to get n by itself. When you divide 630 by 1,000 you would get 0.63.

Step-by-step explanation:

A= L²

50 = L² (do opposite operation to find L)

L = 7.07

x²= L²+ L²

x²= 7.07² + 7.07²

x² = 100 ( do opposite operation to make x the subject)

x = 10

Note: opposite operation of square is square root

Step-by-step explanation:

The function for the given situation is g(x)=7x+20.

Given that, Juan earns $7 per hour plus $20 per week making picture frames.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

a) Let the number of hours in a week be x.

So, function is g(x)=7x+20

y=7x+20

b) Compare y=7x+20 with y=mx+c, we get m=7

So, slope is 7

Therefore, the function for the given situation is g(x)=7x+20.

Answer:

Centre (5,-1) radius =2

Step-by-step explanation:

(x-5)^2+(y+1)^2=4

The standard equation of the circle is

(X-a)^2+(y-b)^2=r^2

Where a,b is centre of the circle and r is the radius of the circle

Compare the equations

So we get a=5,b=-1 and r=2

Centre (5,-1) radius =2

Answer:

sin(–45°) = –sin(45°)

cos(–45°) = cos(45°)

Step-by-step explanation:

The statements which involving cosine and sine are true are sin(–45°) = –sin(45°) and cos(–45°) = cos(45°).

Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.

The main three trigonometric ratios are sine, cosine and tangent functions.

Trigonometric functions are also called as Circular functions.

There are five statements given.

We have the identities that,

sin (-x) = - sin(x) and

cos (-x) = cos x

Using this for each of the statement,

sin(–45°) = –sin(45°) is true.

sin(–45°) = sin(45°) is false

cos(–45°) = –cos(45°) is false

cos(–45°) = cos(45°) is true

For the last one,

cos(–45°) = cos (45°) = sin (45°) ≠ sin(–45°)

So this is false.

Hence the true statements are sin(–45°) = –sin(45°) and cos(–45°) = cos(45°).

Given

Five Digit Flippy Numbers

Required

Determine the number of these digits divisible by 15

Represent the format of this digits as: ABABA

A number is divisible by 15 if and only if it ends with 5 or 0

i.e.

[tex]ABABA = 0B0B0[/tex]

or

[tex]ABABA = 5B5B5[/tex]

The first format [tex]ABABA = 0B0B0[/tex] cannot be considered because the number starts with 0 which means that

[tex]ABABA = B0B0[/tex] ---- This is 4 digits not 5

Taking into consideration: 5B5B5

We know that 15 is a product of 5 and 3

i.e.

[tex]15 = 5 * 3[/tex]

5B5B5 is divisible by 5 because it ends with 5. So, for a number of this format to be divisible by 15, it must be divisible by 3

Numbers in this category are: 50505, 53535, 56565 and 59595

Hence, there are 4 five-digit flippy numbers divisible by 5.

Answer:

0.226

Step-by-step explanation:

Given that:

No wing crack (x) = 70%

Detectable wing crack (y) = 25%

Critical wing crack (z) = 5%

Number of samples (n) = 5

Probability that atleast a plane has critical crack:

1 - p(no critical crack)

Using the multinomial distribution calculator :

P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0)

From the calculator :

P(5,0,0) + p(4,1,0) + p(3,2, 0) + p(2,3,0) + p(1,4,0) + p(0,5,0) = 0.7741

1 - 0.7741 = 0.2259

Answer:

A - Since Elena biked for 8 miles on Saturday, 100% of her distance traveled was 8 miles.

B - Now, on Sunday she traveled 75% of what she traveled on Saturday, which arises from the following calculation:

8 x 0.75 = X

6 = X

So on Sunday she traveled 6 miles.

C - Finally, on Monday she traveled 125% of what she traveled on Saturday, which arises from the following calculation:

8 x 1.25 = X

10 = X

So on Monday she traveled 10 miles.

-5(-2a + 5)

Step-by-step explanation:

10a - 25

-5(-2a + 5)

Answer:

-5(-2a+5)

Step-by-step explanation:

your dividing each number by -5, to get -5 factored.

10 / -5 = -2

-25 / -5 = 5

then you plug it back into the equation with the 5 being factored.

The linear speed of the windmill is 1,960.35 feet per minute.

Given data:

To calculate the linear speed of the windmill, determine the distance traveled by a point on the circumference of the windmill in 1 minute.

The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * radius

Given that the radius of the windmill is 26 feet, the circumference is:

Circumference = 2 * π * 26

Now, the windmill makes 12 full revolutions every 1 minute. Since one revolution is equivalent to one circumference, the total distance traveled in 1 minute is:

Distance = 12 * Circumference

Substituting the value of the circumference:

Distance = 12 * (2 * π * 26)

Simplifying this expression:

Distance = 24 * π * 26

Therefore, the linear speed of the windmill is equal to the distance traveled divided by the time taken, which is 1 minute:

Linear speed = Distance / Time

Linear speed = 24 * π * 26 / 1

Calculating this value, the linear speed of the windmill:

Linear speed ≈ 1,960.35 feet per minute

Hence, the linear speed is 1,960.35 feet per minute.
