(10x-23) how do i find x with 106 as an arc

Answers

If we connect A to D and continue the line up to the circle than
AngBAD=angDAC
10x-23=106/2
10x=53+23
x=7.6

Using the congruence of triangles, the value of x comes to be 15°

What is a circle?

A circle is a locus of a point that moves in a plane such that its distance from a fixed point remains constant.

Connect A to D

So, ∠BAC=53°

From the congruence of triangles

∠BAD=∠CAD =53/2 = 26.5°

Also, ∠BAD=∠ABD (since AD=BD=radius)

So, ∠BDA + ∠BAD + ∠ABD=180°

10x-23 + 26.5+26.5 = 180

10x+30=180

10x=150

x=15°

Hence, Using the congruence of triangles, the value of x comes to be 15°

It takes six analysts forty-two days to write a report. If the report had to be ready in 7 days, how many analysts would be needed?

Answers

If you assume doubling the workers will halve the time taken to finish then 12 analysts will take 21 days
To finish in 7 days (1/6 of 42 days) you would need 6 x the original number = 36 analysts.

Brook’s Law (see Wikipedia) suggests than adding extra analysts will actually slow the project down!
One reason is the extra people tend to get in each others way.

A dessert of both yogurt and idiots were together in the ratio of 1:4 the idiot had 45 said LISA (lol)

Answers

Answer:

11.25

Step-by-step explanation:

Ratio of yogurt : ratio of idiot = 1 : 4

Idiot had 45

Yogurt = x

Ratio of yogurt : ratio of idiot = x : 45

Equate the ratios

1 : 4 = x : 45

1/4 = x/45

Cross product

1 * 45 = 4 * x

45 = 4x

x = 45/4

x = 11.25

Yogurt = x = 11.25

A) 3/56 + 27/56 = 30/56 ÷ 2/2 = 15/28

Step-by-step explanation:

So, there's 3/56 cities that have a lake and 27/56 cities that have a river.

Since the question is asking how much have a lake or river, we add them up.

3/56 + 27/56 = 30/56

(Divide by 2 since that's the common factor)

30/56 ÷ 2/2 = 15/28

8/6 as a mixed number

Answers

Answer:

1  1/3

Step-by-step explanation:

Step 1: Find the whole number

We first want to find the whole number, and to do this we divide the numerator by the denominator. Since we are only interested in whole numbers, we ignore any numbers to the right of the decimal point.

8/6= 1.3333333333333 = 1

Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number.

Step 2: Get the new numerator

To work this out we'll use the whole number we calculated in step one (1) and multiply it by the original denominator (6). The result of that multiplication is then subtracted from the original numerator:

8 - (6 x 1) = 2

Step 3: Our mixed fraction

We've now simplified 8/6 to a mixed number. To see it, we just need to put the whole number together with our new numerator and original denominator:

1  2/6

Step 4: Simplifying our fraction

In this case, our fraction (2/6) can be simplified down further. In order to do that, we need to calculate the GCF (greatest common factor) of those two numbers. You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 2 and 6 is 2.

We can now divide both the new numerator and the denominator by 2 to simplify this fraction down to its lowest terms.

2/2 = 1

6/2 = 3

When we put that together, we can see that our complete answer is,

1  1/3
