can someone explain the answer ?

Answer:

P = 60

Step-by-step explanation:

First, to find the scale factor, or how much bigger the other shape is, you can do so by comparing the two triangles' longest sides.

25       5

----  =  ----

15        3

So the larger triangle is 5/3 times bigger.

This means that all of its other sides with also be 5/3 times bigger.

So:

9 (5/3) = 45/3 = 15

12 (5/3) = 60/3 = 20

25 + 15 + 20 = 60

So the perimeter is 60.

You could have also found the perimeter of the smaller triangle, 9 + 12 + 15 = 36, then multiplied it by the scale factor, which would be:

36 (5/3) = 180/3 = 60

You would get the same thing.

Answer:

-1=(5+x)/6

mulitply both sides by 6

-6=5+x

subtract both sides by 5

-11=x

A

Step-by-step explanation:

formatting is so bad lol

but yeah its the first one because for independent events, the probably of a and b is the product of both probabilities, just like how 0.3*0.4=0.12

Answer:

.75

Step-by-step explanation:

1000-250=750

750/1000 = 3/4

3/4 = .75

Answer:

Radius of the Inner circle:

5.4 is the diameter so find the radius, divide by 2 = 2.7

Next, take pi (3.14) and multiply with the radius (2.7), and use a power of 2.

3.14(2.7)^2 = 22.8906. Then round to the nearest tenth: 23.

Radius of Outer circle:

2.2 is the diameter so find the radius, divide by 2 = 1.1

Next, take pi (3.14) and multiply with the radius (1.1), and use a power of 2.

3.14(1.1)^2 = 3.7994. Then round to the nearest tenth: 4.

Radius of the Inner circle: 23

Radius of Outer circle: 4

Please let me know if it was correct!

Answer:

No, it does not.

Step-by-step explanation:

This does not make a right triangle because in order to have a right triangle you must have 2 of the same numbers.

For example:

900, 800, 900 makes a right triangle

900, 800, 700 does not.

Given:

The function is

[tex]f(x)=x^2+2x+1[/tex]

To find:

The value of [tex]f(x+h)[/tex] in simplified form.

Solution:

We have,

[tex]f(x)=x^2+2x+1[/tex]

Putting [tex]x=x+h[/tex], we get

[tex]f(x+h)=(x+h)^2+2(x+h)+1[/tex]

[tex]f(x+h)=x^2+2xh+h^2+2x+2h+1[/tex]

[tex]f(x+h)=x^2+h^2+2xh+2x+2h+1[/tex]

Therefore, the simplified value of [tex]f(x+h)[/tex] is [tex]x^2+h^2+2xh+2x+2h+1[/tex].

Answer:

126.5

Step-by-step explanation:

Answer:

1. 0.3333333

2. 0.4166666

3. 0.6666666

Step-by-step explanation:

add them all up for a total of 12. then divide 4 into 12 for the probability of number 1. Next, divide 5 into 12 for the probability of green. Finally, add 3 and 5 to get 8 and divide by 12.  

Answer:

First parabola's vertex is (-2,2), which is a minimum.

Second parabola's vertex is (3,2), which is a maximum.

Step-by-step explanation:

Simply, a vertex of a quadratic is a graph's turning point.

The maximum and minimum can be identified by seeing if the graph curves up or down.

Maximum occurs when your graph is facing down.

Minimum occurs when your graph is facing up.

Answer:

The radius is given its 10 in

The diameter is 20 in

Step-by-step explanation:

Two find the diameter given the radius you just multiply by 2

10x2=20 therefore the diameter is 20

Hope this helps :)

Answer:

Radius = 10 inches. Diameter = 20 inches

Step-by-step explanation:

Radius is the halfway point in a circle, the line which says 10 inches. While the diameter is the full length across the circle, which would be the radius times itself, 20.  

Hope this helps!

Answer:

m∠1 = 24°

m∠3 = 66°

m∠6 = 66°

Step-by-step explanation:

They are all near the corners of the rectangle

The corners always equal 90°

But as you can see, they are split down the middle by the X in the rectangle and we have only one angle to go off of; 24°

Since m∠1 is in the same triangle as that angle, and it looks exactly the same, the angle is exactly the same.

m∠3 and m∠6, if you look closely, are also the same. And as I said before, the corners always are 90°. Since 24° is taken from the neighboring triangle, the amount left is 66°, and remember, 24° + x° HAS to equal EXACTLY 90°. So

90 - 24 = 66

So both m∠3 and m∠6 = 66°

O D. Luis had 6 pencils. He placed them in 4 groups. How many were in each group?

Step-by-step explanation:

this makes more sense, since he had 6 pencils and put them in 4 different groups. so, 6 *4 = 24 c:

Answer:

x = -2

Step-by-step explanation:

y = -3x + 2.5

if y = 8.5 then:

8.5 = -3x + 2.5

-3x = 6

x = -2

Answer: (13.5 , 8)

14 + 13 / 2 = 13.5

14 + 2 / 2 = 8

Answer:

(13.5,8)

Step-by-step explanation:

midpoint formula = [tex](\frac{x_{1} +x_{2} }{2}, \frac{y_{1} +y_{2} }{2})[/tex]

[tex](\frac{14 +13 }{2}, \frac{14 +2 }{2})[/tex] = (13.5,8)
