Answer: So we'll use trig to solve this because it's a right triangle. The hypotenuse is the ladder (h) and the two smaller sides are the ground and the vertical wall (w).
That angle ladder makes with the ground = €
SOH: sin € = opposite/hypotenuse
No the ladder won't be safe!!!
Now let's make it safe:
The ladder's length (w) is constant, so stays 12
So now let's ask in an inequality what height will be safe (75° or less)
what does that mean?? well as long as you put the ladder against the wall so that the height from ground to top of the ladder is < 11.6 ft!!
Hope that helps! :-D
Step-by-step explanation:
Mr. Dieter wants to tile the family room in his basement. He has selected a pattern of square tiles that measure 9 inches by 9 inches each. The shape of the floor to be tiled is shown below. a. What is the area of the family room in square feet? b. How many of the 9 inch by 9 inch tiles will it take to cover the floor? (NOTE: You will need to convert the area in Part a from square feet to square inches.) c. If the tile is sold only in boxes of 12 tiles per box, how many boxes will Mr. Dieter have to buy to tile the family room?
Answer:
146 ft²
21.6 tiles
1.8 boxes
Step-by-step explanation:
Please find attached an image of the family room used in answering this question
the family room has the following shapes : 2 triangles and one rectangle
the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together
area of a rectangle = length x breadth
16 x 7 = 112 ft²
Area of a triangle = 1/2 x base x height
Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²
Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²
Sum of the areas = 112 + 6 + 28 = 146 ft²
b.
1. First convert the area of the room to inches
1 ft = 12 in
146 x 12 = 1752 in²
2. the next step is to determine the area of the tile
area of a square = length²
9² = 81 in²
3. Divide the area of the room by the area of the tile
1752 / 81 = 21.6 tiles
c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes

what is 4(11h +3g)?????
Answer:
[tex]12g+44h[/tex]
Step-by-step explanation:
Step 1: Rearrange terms
[tex]4(11h+3g)\to4(3g+11h)[/tex]
Step 2: Distribute
[tex]4(3g+11h)\to12g+44h[/tex]
Answer:
44h+12g
Step-by-step explanation:
Okay, so, this a standard algebraic expanding problem, so:
We take our 4(11h + 3g)
because we have parenthesis, we have to distribute the 4:
4 x 11h + 4 x 3g = 44h + 12g
So, 4(11h + 3g) expanded is 44h + 12g

What is the the value of x. Pleaseeeee help I’ll mark you brainlist
Answer:
11.75
Step-by-step explanation:
All angles of a right triangle equal 180°.
So you have to do a substitution method to find the value of x.
Which leaves us with: angle 'A' = 5 × 11.75, angle 'B' = ((3 × 11.75) -4), and angle 'C' = 90. If you add all of them together it is equivalent to 180°.
∴ x = 11.75
Kieth has landscaping bricks that are 0.75 feet long. Kieth puts 19 bricks end to end along a sidewalk. What is the total length of all thee red bricks he uses. Enter your answer in the box
Answer: 14.25 ft
Step-by-step explanation:
Assuming all the bricks used are red:
Keith puts 19 bricks end to end along a sidewalk and each one of those bricks is 0.75 ft long.
When put end to end therefore, the total length will be that length multiplied by the number of bricks laid:
Total length = Number of bricks laid * Length of each brick
= 19 * 0.75
= 14.25 ft

In the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children visiting the center each child gets same number of candy canes how maby candy canes does each child get round your answer to nearest tenth
Answer: 80.7
Step-by-step explanation:
From the question, we are informed that in the week leading up to Christmas the galaxy shopping center gives away 6700 candy canes to first 83 children that visits the center and that each child gets same number of candy canes.
If it's shared equally among the children, each child will get:
= 6700 / 83
= 80.7 to the nearest tenth.

can someone please double check this for me?
Answer:
False
True
False
True
Step-by-step explanation:
The 4th option should be correct because the y-intercept on A is greater than the one in B,
A: y = -1/3x + 0 (usually when the y-intercept ain't appearing it means it's 0).
B: y = -1/3 - 2
As we know 0 is greater than -2 because it's closer to being a positive number, so 0 is not positive or negative; 0 is greater than any negative number but smaller than any positive numer so,
0 > -2.
Therefore the last option is true.

Two angles are supplementary. One angle is 25°. What is the measure of the other angle?
Answer:
The other angle is 155°.
Step-by-step explanation:
Supplementary angles are two angles that have a sum of 180°.
I found my answer my subtracting 25 from 180 (180-25) and my difference was 155.
And, 155 + 25 = 180°.
Therefore, the other angle is 155°.
What is the approximate volume of the cylinder? cylinder with height of 9 feet and radius of 4 feet.
answer choices: 324, 425.16, 734.76, 1,017,36
Answer:
Step-by-step explanation:
Formula
V = pi r^2 h
Givens
H = 9 feet
r = 4 feet
Solution
V = 3.14 * 4^2 * 9
V = 3.14 * 16 * 9
V = 452 square feet. Perhaps that 425 has a reverse digit in it. I'm sure that's the problem.

Answer:
x > 5/3
Step-by-step explanation:
In general, inequalities are solved the same way that equations are: undo what is done to the variable. (Whatever you do to one side of the inequality, you must also do to the other side.)
If you were to evaluate this inequality for some value of x, you would ...
multiply by 3subtract 5When solving for x, you undo these operations in reverse order. You undo the "subtract 5" by doing "add 5" to both sides of the inequality:
3x -5 +5 > 0 +5
3x > 5
You undo the "multiply by 3" by doing "divide by 3" to both sides of the inequality:
(3x)/3 > 5/3
x > 5/3 . . . . . . . the solution
__
Additional comment
The only difference between solving an equation and solving an inequality is that multiplication or division by a negative number reverses the comparison symbol.
Consider -1 > -2. When this is multiplied by -1, it becomes 1 < 2, with the comparison reversed.
__
As you can see, as long as multiplication and division are with positive numbers, the actual comparison symbol doesn't matter:
3x -5 > 0 ⇒ x > 5/3
3x -5 = 0 ⇒ x = 5/3
3x -5 < 0 ⇒ x < 5/3
