Answer:

[tex]\huge\boxed{\sf r = 37\ mm}[/tex]

Step-by-step explanation:

Let the radius be r

UV is tangent to the circle T which means UV is perpendicular to UT, that makes ΔUVT a right-angled triangle.

Which means:

∠TUV = 90°

So, We can use pythagoras theorem to find the radius of the circle.

In the Δ:

Hypotenuse = r + 9

Base = r

Perpendicular = 12

Pythagoras Theorem:

(Hypotenuse)² = (Base)² + (Perpendicular)²

(6 + r)² = (r)² + (22)²

(6)² + 2(6)(r) + (r)² = r² + 484

36 + 12r + r² = r² + 484

Subtract r² to both sides

36 + 12r = 484

Subtract 36 to both sides

12r = 484 - 36

12r = 448

Divide both sides by 12

r = 448/12

r = 37 mm

Answer:

28 cm per year

5.5 years

Step-by-step explanation:

In three years time, the height of the tree grew from 190 to 274, that's an increase of 84 cm. Divice that by the number of years it took. So you get this calculation:

(274-190)/3 = 28

When the tree was 344 centimeters tall, the increase was 344-190 = 154. Divide that by the 28 found earlier to get 154/28 = 5.5 years.

hello bro

Answer:

26 y + 5

Step-by-step explanation:

Simplify the following:

7 3 y + 4 3 y - 3 y - 2 2 y + 5

7×3 = 21:

21 y + 4 3 y - 3 y - 2 2 y + 5

-2×2 = -4:

21 y + 4 3 y - 3 y + -4 y + 5

4×3 = 12:

21 y + 12 y - 3 y - 4 y + 5

Grouping like terms, 21 y + 12 y - 3 y - 4 y + 5 = (21 y - 4 y + 12 y - 3 y) + 5:

(21 y - 4 y + 12 y - 3 y) + 5

21 y - 4 y + 12 y - 3 y = 26 y:

Answer: 26 y + 5

Answer:

B. 204 pens

Step-by-step explanation:

If you have 10 boxes of 30 pens each, the problem would be like so:

10 x 30 = 300

Now, since we have 32 workers that each take 3, this turns into:

32 x 3 = 96

Finally, because 300 is the total amount of pens and 96 is the amount taken, we just subtract to get:

300 - 96 = 204 pens

An ounce unit will best represent each scenario.

The average weight of an elephant is around 3000-4000 kg.

The average weight of a mouse = 15-20 grams

The average weight of a puppy = 25-30kg

It is given that

Weight of the elephant = [tex]1.5 * 10^5[/tex] units ≈150000 units

Weight of the mouse = [tex]6.3*10^2[/tex] units ≈630 units

Weight of the puppy = [tex]1.2*10^3[/tex] units ≈1200 units

1 ounce = 0.0253495 kg

150000 ounces = 3800kg, near to actual value

630 ounces = 16kg, near to actual value

1200 ounces = 30kg, near to actual value

Therefore, an ounce unit will best represent each scenario.

Answer:

Step-by-step explanation:

small=s,    s=3.99

large=l,       l=19.20

10s+8l=192.20

20s+l=99

we can see that in the second equation, 20s+l=99

l=99-20s

lets replace l in the first equation

10s+8(99-20s)=192.20

10s+792-160s=192.20

-150s=-792+192.20

150s=599.80

s=3.99

l=99-20(3.99)=99-79.80=19.20

Answer:

19

Step-by-step explanation:

You can set up a system of equations.

x=small, and y = large.

10x+8y=$192

20x+1y=$99

you can multiply the first equation by -2 to get rid of x:

20x+1y=$99

-20x-16y=-$384

when you combine them, you get:

-15y=$-285

you can divide by -15 and you get:

y=19, so 1 large equals $19

Answer:

A, B, D, E

Step-by-step explanation:

To find if something is equal to fifty percent, split the second number in half.

For example, lets use option D.

32/2=16

16 is the first number in the option, meaning it is 50%.

Lets use an example where it wouldn't work. In this case, option C.

12/2=6

6≠9

Meaning 9 is not 50% of 12.

Answer:

Number of planes needed = total number of people ÷ number of people 1 plane can hold

⇒ number of planes needed = 49 ÷ 6 = 8 1/6 = 8 remainder 1

Therefore, 9 planes will be needed to transport 49 people.

8 planes will be full and 1 plane will not be full.

There will be 1 person in the plane that is not full.

j'ai écrit ci-dessous

Step-by-step explanation:

Salut, j'utilise un traducteur, mais revenons à votre question

Je ne suis donc pas sûr de la question a, mais j'essaierai d'y répondre plus tard.

Pour la question b, il a utilisé la formule "a-b" je pense. C'est déjà indiqué dans le tableau. D'accord, je vais essayer de trouver la question a maintenant !

Edit

salut je suis de retour! donc d'après mes découvertes, le pgcd (si pgcd est le plus grand diviseur commen) serait 207. C'est parce que vous pouvez diviser les deux par 207, et une fois que vous le faites, vous ne pouvez plus le diviser par des nombres égaux.

2277/207 = 11

1449/207 = 7

J'espère que cela t'aides!

Step-by-step explanation:

use this equation

y = mx + c

m is the gradient

c is the y intercept

m is

m is rise/run

the line rises from 3 to 10

so rise is 7

the line runs from 0 to 3.5

so run is 3.5

m = 7/3.5

m = 2

c is

y-intercept is where the line is equal to x=0

that point is

(0, 3)

so y int is 3

c = 3

put back into equation

y = mx + c
