ASA Congruence Theorem

Answer:

8

Step-by-step explanation:

If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:

8 * x / 2 = 32

Now, solve:

[tex]8x/2=32\\4x=32\\x=8[/tex]

Answer:

x=8

Step-by-step explanation:

Area is equal to half of the base times the height. We are told that the area is 32and the base is 8, so we can write this equation:

32=1/2(8)h

Multiply 1/2 by 8:

32=4h

Divide both sides by 4:

h=8

So now we know that x (the height) equals 8.

Answer: the fourth triangle

Step-by-step explanation:

I got it right :)

Answer:

The 4th triangle

Step-by-step explanation:

Answer:

A. only inequality 1.

Step-by-step explanation:

The inequality 1 can be written as

- 5 = 1 - 3d

- 5 - 1 = - 3d

- 3d = - 6

d = 2

Now the inequality 2 can be written as

- 1 =( 1 - d) / 3

- 3 = 1 - d

d = 1 + 3

d = 4

So the answer is A only inequality 1.

Hope it will help :)

Answer:

150 by 18 or 20

Step-by-step explanation:

Answer:

3x+6

Step-by-step explanation:

just multiply 3*x=3x and 3*2=6 so  3x+6

Step-by-step explanation:

since it's an Equilateral triangle

180/3=60°

6x=60

x=10°

Answer:

1/3 is the answer

Step-by-step explanation:

Answer:

hi! so first you make 2/5 into 6/15 and the answer would be 5/15 (or 1/3 if you simplify it) because 6/15+5/15=11/15

Answer:

We are solving for the area so; A=134.16

Step-by-step explanation:

Here is the formula for finding area of a sector:

A = [tex]\pi r^{2}[/tex] × θ° ÷ 360°

where theta is the angle of the sector you wish to find, and r is the radius of the circle.

Substitute the numbers in and you get:

[tex]\frac{25\pi }{2} unit ^{2}[/tex]

You should find 39.26991 as your answer (or any number rounded according to the value of pi)

Answer:

The function that is incorrect is the third option, the option where the Domain's 0 is pointing to two Ranges.

Answer: 197.3 ok bye

Answer:

197.3

Step-by-step explanation:

Answer:

2/2, 7/8, 3/4, 1/2

Step-by-step explanation:

First you have to change it in to fractions that all have the same denominators. 4/8, 7/8, 6/8, 1

Now you put them in order.  

Answer: 13

Step-by-step explanation:

Let the number that in thinking of be represented by x.

I multiply by 11 and add 22 will give the same answer as multiplying by 4 and adding 113. This.csn be firmed into an equation as:

(11 × x) + 22 = (4 × x) + 113

11x + 22 = 4x + 113

Collect like terms

11x - 4x = 113 - 22

7x = 91

x = 91/7

x = 13.

The number is 13

Answer:

Step-by-step explanation:

So we know that Alex is trying to save $230.

He already has forty dollars so we can take forty away from two hundred and thirty. This leaves us with $190 that we need to save.

If he is saving $38 per week. We can divide or estimate and multiply. I prefer to multiply so that is the method I will use right now.

38×5= 190

Therefore, Alex will have enough money to buy a tablet in five weeks.

I hope I am correct and I explained this in a way that you can understand and do it yourself next time.

Answer:

$3779.14

Step-by-step explanation:

I'm going to assume that the interest is compounding annually

We have the following equation

PV(1+i)ⁿ

Plug in our numbers and we have

3000(1+.08)³

3000(1.259712)=3779.136 which rounds to 3779.14

Answer:

5 + i

Step-by-step explanation:

Combine real part ans combine imaginary parts

2 + 3i + 3 - 2i = 2 + 3 + 3i - 2i

                      = 5 + i

Answer:

5 and 1i

Step-by-step explanation:

So you’re adding the following complex numbers: (2 + 3i) + (3 - 2i)

normally if you see a (-) in front of a number, that means it’s negative so we’re gonna think about this as -2i and positive 3.

so you’re gonna want to take the 2 regular while numbers (without the variable) and then add those together. they’re like numbers so neither of them have a variable, which means they can easily be added, but you can’t add a number like 7 to a number like 9h because there’s a variable.

Now that you’ve added the 2 and 3, you get 5 right? so now you’re gonna take the 3i and -2i, and add those together. since the number 3i is bigger than -2i, the ending number after you add those is gonna be positive, and it’s gonna be 1i.

now i’m not sure if you’re supposed to make an equation out of this but you’re answer will be 5 and 1i or 5 + 1i

also if you don’t want to put 1i, 1i is the same as just “i”. so you can put 5 + i :)

hope this helped!!
