Can a triangle be classified as both isosceles AND obtuse? Why or why not?

Answer:

L = 55 in, W = 20 in

Step-by-step explanation:

Hi there!

First we have to set up an equation for the length, which can be written as 3x - 5.

The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.

l = 3x - 5

w = x

[tex]2(3x-5) + 2(x) = 150[/tex]

Now we just have to solve!

[tex]6x - 10 + 2x = 150[/tex]

When we combine like terms and add ten to both sides, we are left with

[tex]8x = 160[/tex], which means x = 20

Using this, that means the width is 20

We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]

This means the length is 55.

Answer:

620 cm²

Step-by-step explanation:

First I'll describe the net. There are 3 rectangles and 2 triangles. The triangles are identical and 2 out 3 of the rectangles are the same.

So, we know that the two similar rectangles have measurements of 13cm x 10cm. So, that's 130 cm² for one such rectangle. Add the other one and we get 260 cm².

The bottom rectangle has dimensions of 10cm x 24 cm, or 240 cm². Add that to our previous total and we'll get 500 cm².

On to the triangles. Now, we know that 1. these are isosceles triangles, and 2. they have a height of 5 cm. We can pretend to cut them in half at their highest point, which would give us 4 triangles with height 5 and length 12. Now, if you put two identical triangles together, it's a four-sided shape, and you can just multiply length by width. Let's do that.

Now we have 2 rectangles, each with width 5 and length 12. Calculate the area for each, and now we have 2 rectangles with area 60 cm². Add them together....120cm².

Add that to our previous total, and we'll get 620 cm². That should be the surface area of your prism :D

Answer:

22=90 23=15 24=60 25=0.75 26=70 37=$0.58

Step-by-step explanation:

22. So, we can divide 360 kmh by 4 hours

so 360/4 =90

So 90 kmh in 1 hr

23

So, we can divide 3 packages by $15

so 15÷3 = $5

So $5 per package

24  So, we can divide 720 m by 12s

So, 720/12= 60

60 m in 1 s

25

So, we can divide $4.50 by 6

So, we get $0.75

26

So, we can divide 210 words by 3 min

So, 210÷3=70

70 words per minute

27

So, we can divide 23.20 by 40l

So, 23.20÷40 = 0.58

$0.58

Answer:

(0.5)

Step-by-step explanation:

x + y = 5

3x - y = -5

Put "y" on one side to isolate

3x - y = -5

3x = y - 5

3x + 5 = y

Plug "3x + 5" in for "y" in the second equation

x + (3x + 5) = 5

4x + 5 = 5

4x = 0

x = 0

Plug  "0" in for "x" in any one of the equations

0 + y = 5

y = 5

To check, plug in "0" for "x" into the first equation and make sure they get the same answers

3(0) - y = -5

0 - y = -5

y = 5

Step-by-step explanation:

15/2=x/3

15×3/2=x

45/2=x

22.5=x

Answer:

22.5

Step-by-step explanation:

First find out the ratio x : 1

2 / 2 = 1

15 /2 = 7.5

Now you have this ratio

7.5 : 1

Now times each value by 3 to get the answer :

22.5 : 3

x = 22.5

hope this helps :)

.47 would be your probability of randomly selecting but your'e solving geometrically so think how many trials until successful.

use u x(mean)= 1/.47 to get around 2.13

Answer:

2.13

Step-by-step explanation:

.47 is the probability of randomly selecting, you have to find how many trials until successful. x(mean)= 1/.47 to get around 2.13

Answer:

638 miles

Step-by-step explanation:

Key skills needed: Proportions, Unit Rates

1) The car can go 464 miles with 16 gallons of gasoline. We need to find how many miles each gallon gasoline results in.

To find the miles per gallon, we would do 464 miles/16 gallons --> 29 mpg

This means each gallon lets the car run 29 miles.

2) To find out how many miles 22 gallons is, we then do 29 x 22, which is 638 miles.

Therefore, your answer is 638.

Hope you understood and have a nice day!!

Step-by-step explanation:

Answer:

D = 1 8.87961173

Round off to the whole number

D= 19m

Explanation of results

So to find d you will use the trigonometry formula

So you are given the

Degree which is 39°

and the hypotenuse which is 30m

Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,

[tex] \sin(39) = \frac{d}{30} [/tex]

then you are going to isolate d on the right by multiplying 30 on both sides.

It will look like

30 Sin 39

So, just put this in the calculator

Answer:

Step-by-step explanation:

Given m ∠ Q P S = 4 7 ∘ m∠QPS=47 ∘ m, angle, Q, P, S, equals, 47, degrees m ∠ R P S = 3 x − 3 8 ∘ m∠RPS=3x−38 ∘ m, angle, R, P, S, equals, 3, x, minus, 38, degrees m ∠ Q P R = 7 x − 9 5 ∘ m∠QPR=7x−95 ∘

Sum of angles in a triangle = 180°

47° + 3 x − 3 8 ∘ + 7x - 95° = 180°

10x + 180° = 180°

Answer: 31°

Step-by-step explanation:

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20
