Answer: About 9.2
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem. We are solving for the hypotenuse which is the "c" variable in the formula.
a² + b² = c²
7² + 6² = c²
7² + 6² = c²
49 + 36 = c²
85 = c²
[tex]\sqrt{85}[/tex] = c
9.2 ≈ c

Answer:
1/2(n -10) = -4
Step-by-step explanation:
Understanding the given sentence as a math sentence requires that you first understand it as an English sentence.
Parsing the EnglishThe subject of the English sentence is "difference". We know that a difference in math is two values separated by a minus sign. Having understood that, we need to identify the two values involved.
The descriptor of "difference" in the English sentence is "of a number n and 10." This tells us the two values are "n" and "10". The first one listed goes on the left of the minus sign. So, the difference we're talking about is ...
(n -10)
The English sentence tells us that this difference is multiplied by 1/2. The math equivalent is shown as ...
[tex]\dfrac{1}{2}(n-10)[/tex]
When the English tells us the result of this operation, it means this value is equal to that result. We are told this value is equal to -4
Writing the equationWe now know the left- and right-sides of the equation being described in English. That means the equation described is ...
[tex]\dfrac{1}{2}(n-10)=-4[/tex]
- 5/6 x -6/7 x -4/5
- 4/5 x -5/8 x 8/9

15 dollars per dough (d)= 165 dollars
Hope this helps! ;-)
~Master Chief
Let's solve this problem step by step:
So we know that Isaac sold 'x' number of tubs of dough
⇒ and that each tub of dough is worth 15 dollars
⇒ means he made '[tex]15*x'[/tex] dollars from selling 'x' tubs of dough
⇒ coincidently, we know that he made a total of $165
⇒ So the equation is: [tex]15x = 165[/tex]
Answer: 15x = 165

45. A pile of logs has 24 logs in the bottom layer, 23 in the second layer, 22 in the third, and so on. The top layer contains 10 logs. Find the total number of logs in the pile.
The total number of logs in the pile will be 255.
What is the sum of an arithmetic sequence?Let a₁ be the first term, L be the last term, n be the number of terms, and d be a common difference.
Then the sum of the arithmetic sequence will be
S = (n / 2)[a₁ + L]
S = (n/2) [2a + (n − 1) d]
A pile of logs has 24 logs in the bottom layer, 23 in the second layer, 22 in the third, and so on. The top layer contains 10 logs.
The common difference is negative 1.
Then the nth term of the arithmetic sequence is given as,
10 = 24 + (n - 1) x (-1)
n - 1 = 14
n = 15
Then the total number of logs in the pile will be
S = (15/2) [24 + 10]
S = 7.5 x 34
S = 255
The total number of logs in the pile will be 255.

Answer:
the ladder is 5 ft from the base of the wall.
--
To find the unknown length, we need to use the Pythagorean Theorem
The Pythagorean Theorem is a²+b²=c²Since the legs are x and 12 this means that a=x and b=12
Also, since the hypotenuse is 13, this means that c=13.
Plug in a=x, b=12, c=13x²+12²=13²x²+144=169Subtract 144 from both sides.
x²=169-144Combine like terms.
x²=25Take the square root of both sides.
x=√25x=5 Simplify the square root.
Answer:
So the solution is x=5 which means that the foot of the ladder is 5 ft from the base of the wall.

Harper wants to put wood shavings in her rabbit's cage. The floor of the cage measures 1 yard wide by 6 feet long. One bag of shavings cover 10 square feet.
How many bags will Harper have to buy to cover the floor of the cage? Explain
Harper will have to buy _____ bag(s) to cover the floor because the area of the floor is _____ square foot/feet.
Help please :-(
Answer:
she would need 2 bags because it is 18 but covers 10 square feet
Step-by-step explanation:
Width = 1 yard = 3 feet
Length = 6 feet
Square feet(area) of the floor = 6ft × 3ft = 18sqft
1 bag = 10sqft
x bag = 18 sqft
x bags = (18 × 1)/10
= 1.8 bags
2 bags

Danielle is writing an equation to find the length of the third side of the right triangle. Find her mistake and correct it.
Write the equation for each translation of the graph of y=| 1/2x-2|+3
One unit to the left
one unit to the right
Answer:
Answer: for One Unit to the Left: |1/2 x -3/2|+3
Step-by-step explanation: When translating to the left, you are going to end up with f(x-(-1)) meaning x+1. Even though left means subtracting, in translation it’s adding. (I hope that made sense).
that would create the equation |1/2x(x+1)-2|+3
If you solve that, it would simplify to |1/2x-3/2| which is the answer
