that is correct trust me I'm in 10th grade

Answer:

16 feet is the correct answer to this problem.

Answer:

The answer is 80 and 89 because on the last sentence states that the average lie between these two numbers

Step-by-step explanation: plz mark brainliest if im right

Answer:

the answer would be 132

Step-by-step explanation:

180-48=132

a polynomial is an expression consisting of variables and coefficients

and "-10" doesn't match the requirements

Answer:

Your answer would be 189

Step-by-step explanation:

if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

Answer:

1.17

Step-by-step explanation:

(MUCH BETTER!)

From the definition of the sin of an angle, you know:

sin(45°) = AC/AB = 4/AB   ⇒   AB = 4/sin(45°) ≈ 5.6569

sin(63°) = AC/AD = 4/AD   ⇒   AD = 4/sin(63°) ≈ 4.4893

Then the difference AB-AD is:

AB -AD = 5.6569 -4.4893 = 1.1676

AB -AD ≈ 1.17 units

Sorry this took me so long to answer!

Answer:

fourth one

Step-by-step explanation:

Answer:

t = 1

Step-by-step explanation:

5t + 8 = 13

Subtract 8 from both sides

5t + 8 - 8 = 13 - 8

5t = 5

Divide both sides by 5

5t/5 = 5/5

t = 1

Check:

5t + 8 = 13

5(1) + 8 = 13

5 + 8 = 13

Choose two coordinates. I will choose the ones you chose, (-2, -3) and (0, 1).

Find the slope first using the slope equation: [tex]\frac{y2-y1}{x2-x1}[/tex]

y2 is 1, y1 is -3, x2 is 0, and x1 is -2.

[tex]\frac{1-(-3)}{0-(-2)}[/tex]

[tex]\frac{1+3}{0+2}[/tex]

[tex]\frac{4}{2}[/tex]

m = [tex]2[/tex]

The slope is 2.

Now that we found out the slope, we can start to assemble our equation. The m in the equation y = mx + b stands for the slope.

Now the equation is: y = 2x + b.

We need to figure out the y-intercept next. The b in the equation stands for the y-intercept. Choose one coordinate. I will chose (0, 1). x = 0 and y = 1. Substitute 0 in for x and 1 into y.

y = 2x + b

1 = 2(0) + b

1 = 0 + b

1 = b

Now we know what b is. Plug in 1 for b in the equation.

y = 2x + 1

I hope this helps! Let me know if I got something wrong and I'll fix it.

Answer:The first 1 is 98

The second one I have no idea sorry-

Same with third one

and forth 1 sorry I cant help u with the last 3 I hope someone else does :)

Answer:

x= 8

Step-by-step explanation:

srry i need the points so i can finish my work so i can go to sleep

Answer:

A.

Step-by-step explanation:

Hi there!

By factoring the trinomial, we end with (x-9)(x-4)

However, we aren’t done yet. To find the zeros, set each expression equal to zero, so it looks something like this.

0 = x - 9

0 = x - 4

Using orders of operations, x = 9 and x = 4

Therefore,  A is your answer.

I hope this helps!

Answer:

1 solution

no solution

infinitely many

1 solution

Step-by-step explanation:

1. 2.3x-7=-7

2.3x=0

x=0

2. 3x=5+3x

0x=5

x=5/0

That’s undefined

3. 40-4x=4(10-x)

40-4x=40-4x

They both are equal no matter what. So, infinitrly many

4. -7+x=-(x+7)

-7+x=-x-7

2x=0

x=0

1 solution I.e 0

Answer:   1-  One solution

                2- No solution

                3- Infinite

               4-  one solution

Answer: 10 and a half For ivy For Hayden 8 half

Step-by-step explanation: because ivy gave Her mother 2 each and her father half and for her brother

Answer:

Given to father by Ivy: 12/2=6

Given to father by Hayden: 10/2=5

Now,

Chocolates given to mother by Ivy: 2

Chocolates given to mother by Hayden: 2

Now total chocolates given by Ivy to mother and father: 6+2 = 8

Now total chocolates given by Hayden to mother and father: 5+2=7

Now total chocolates left  with Ivy 12-8=4

Now total chocolates left with Hayden: 10-7= 3

Thus ivy and Hayden has  4&3 chocolates respectively

Answer:

d

Step-by-step explanation:

Answer:

d = ab / ec

Step-by-step explanation:

ab / c = d x e

times both sides with c:  ab = d x e x c

divide both sides with e x c:  ab / ec = d

Answer:

A

Step-by-step explanation:

b and 55° form a right angle = 90° , then

b + 55° = 90° ( subtract 55° from both sides )

b = 35°
