Answer 1

D1=25°

B3=25°

B1=30°

Step-by-step explanation:

1. O1+O2=360°(revolution)

310°+O2=360°

O2=360°-310°

=50°

O2=2D1(centre theorem)

50°=2D1

D1=25°

2. D1=B3=25°(tan chord theorem)

3. B2+B3=A=60°(tan chord theorem)

B1+B2+B3=90°(Radius perpendicular Tangent)

B1+60°=90°

B1=90°-60°

=30°

Step-by-step explanation:

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer

Answers

Answer:

475 children

Step-by-step explanation:

A restaurant has many vistors over the weekend.4/9 of the visitors are adults. If there were 380 adults, how many visitors were children? Answer

Step 1

We find the total number of visitors the restaurant had over the weekend. This is calculated as:

Let the total number of visitors = x

4/9 × Total number of visitors = 380 Adults

4/9 × x = 380

4x/9 = 380

Cross Multiply

4x = 9 × 380

x = 9 × 380/4

x = 855 visitors.

Step 2

The number of visitors that were children is calculated as:

Total number of visitors - Number of Adults

= 855 visitors - 380 Adults

= 475 children

Question 7: The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg. How
much more does Anne's cat weigh?
A) 28 kg
B) 2 kg
C) 8 kg
D) 9.3 kg

Answers

Answer: C

Step-by-step explanation: The ratio shows that Anne's cat is 2kg heavier, but Meg's cat weighs 20kg which is 4 times what the ratio shows the weight is, so the difference of the weight is also 4 times greater, which is 8kg!

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

What is the ratio?

The utilization of two or more additional numbers that compares is known as the ratio.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The ratio of M's to A's cat is 5:7. Meg's cat weighs 20 kg.

Let 'x' be the weight of Anne's cat. Then the equation is given as,

5 / 7 = 20 / x

Simplify the equation, then we have

5 / 7 = 20 / x

1 / 7 = 4 / x

x = 28 kg

The value of weight of Anne's cat will be 28 kg. Then the correct option is A.

Write the number below as a fraction in its simplest form 0.˙49˙9 (more clearer picture is attached here)

Answers

Answer:

499/999

Step-by-step explanation:

The decimal number written is:

0.499...

Such that these 3 decimals are repeated as:

0.499499499...

Let's define this number as k

k = 0.499...

Let's multiply this number by 1000 (the same number of zeros as important decimals after the decimal point)

we get:

1000*k = (1000)*(0.499...) = 499.499...

Now we can subtract the original number k, so we get:

1000*k - k = 499.499... - 0.499...

In this way, we remove the part after the decimal point:

1000*k - k = 499.499... - 0.499...

(1000 - 1)*k = 499

999*k = 499

Now we can divide both sides by 999

(999*k)/999 = 499/999

k = 499/999

The fraction notation of our number is 499/999 (and this is the simplest form)

Slope: (y2 - y1)/(x2-x1) where x and y indicate the coordinates of two points

Slope = (4-0)/(0-(-2) = 4/2 = 2

y intercept is where the line intercepts the y axis: it happens in (0;4)

Hey! It's me again! You told me to answer this, so I will deliver ☺

Answer:

15/21

Step-by-step Explanation:

Because 1/3 and 2/7 do not have the same denominator, we will have to multiply them to get one that they'll both share.

In this case, you multiply both denominators, 3 and 7, to get 21.

We do the same with the numerators, but in a different way.

We're gonna multiply the numerators by the OTHER fractions' denominators this time. So, we do this:

1 x 7 = 7

2 x 3 = 6

We end up getting these fractions:

7/21

6/21

And now, we just subtract 6 from 21, to get 15.

And you get 15/21.

multiply both sides by 6:

24/3r³ = 1

we want to take 0.81% of it and add to the total each year so

322,000,000*0.81%=2,608,200

322,000,000+2,608,200=324,608,200

and now do that for 22 more years so

We get 387,649,305.98 as our population

387,649,305.98 -------> 388,000,000
