Hi there!
[tex]\huge\boxed{6cm}[/tex]
We can use the Pythagorean Theorem to solve:
Use the formula a² + b² = c² where:
"a" and "b" are the legs
"c" = Hypotenuse
The diagonal side, or the length of the ladder is 10cm, and one of the legs of the triangle is 8cm, therefore:
(8)² + b² = 10²
64 + b² = 100
Subtract 64 from both sides:
b² = 36
Take the square root of both sides:
√b² = √36
b = 6 cm. This is the distance of the wall from the foot of the letter.
Edit: Typo.
Answer:
6 cm.
Step-by-step explanation:
When you imagine the sentence, it is a right angled triangle. In this case, it's a Pythagoras Theorem. The formula for it is:
a²(opposite) + b²(adjacent) = c²(hypotenuse)
The vertical wall is the opposite, the distance between the foot of the ladder and the wall is the adjacent, while the ladder is the hypotenuse.
We have the measurements except for the adjacent. So it will be:
c² - a² = b²
10² - 8² = b²
100 - 64 = b²
36 = b²
√36 = b
b = 6 cm
The answer is 6 cm.
Yesterday, the temperature dropped 4 degrees every hour. Which number sentence best shows how much the temperature changed in 6 hours?
A. 6(4) = 24
B. 6(-4) = -24
C. -6(-4) = 24
D. -6(4) = -24
Answer:
I think it is b
Step-by-step explanation:
if it drops by 4 it would be negative. 6 hours passed so it would be positive

Answer:
The least common denominator is 21.
Step-by-step explanation:
First, you must find the least common factor of the two:
3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30
7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70
Second, you must increase the fractions:
[tex]\frac{1}{3}[/tex] × [tex]\frac{7}{7}[/tex] = [tex]\frac{7}{21}[/tex] [tex]\frac{3}{7}[/tex] × [tex]\frac{3}{3}[/tex] = [tex]\frac{9}{21}[/tex]

? (4x – 2) – 2 (3x + 3) = 9+2 (x + 4) true?
Answer:
No
Step-by-step explanation:
Let's plug x = 5
(20 - 2) - 2(15 + 3) = 9 + 2(5 + 4)
Simplify -->
18 - 30 + 6 = 9 + 10 + 8
--> -12 + 6 = -6 --> 19 + 8 = 27
-6 is not equal to 27
thus, it is false

Callie has completed 5/12 of a project for her English class. Express this value as a decimal. Then, state if the decimal is terminating or repeating.
Answer:
0.42 it is terminating because it goes 66666 but then changes to a 7 at the end
Step-by-step explanation:
5/12 is just like a division problem. You divide 5 by 12 to get 0.416666667 which is the full answer and you take the first two numbers after the decimal to be your answer. But if there is a 5 or higher after the second number you can round it to its nearest tenth.

Answer:
3. 17x + 5 = 90° ( alternate exterior angles are equal)
=> 17x + = 90 – 5
=> 17x = 85
=> x = 85/17
=> x = 5
4. 63° + c + 110° + 75° + 50° = 360 °
=> c + 298° = 360°
=> c = 360° – 298°
=> c = 62 °

As per arithmetic progression, the number comes after 28 in the given series is 24.
What is arithmetic progression?"An arithmetic progression is a sequence of numbers such that the difference between the consecutive terms is constant. "
The first term is = 40.
The common difference is (d) = 36 - 40 = 32 - 36 = 32 - 28 = - 4.
Here, the given series is in arithmetic progression.
Therefore, the next term after 28 is
= 28 - 4
= 24

Write the expression: the product of 2 and a number, divided by the difference of 9 and another number
Answer:
2n ÷ 9 - x
Step-by-step explanation:
The product of 2 and a number, I used "n" to replace the number. Putting a number next to a variable means multiplying.
So we have 2n and divide by the difference (subtracting) of 9 and ANOTHER number, that means we need a different variable for this I used "x".
And that's how I got 2n ÷ 9 - x as my answer.
Hope that helps and have a great day!

Given f (x)= -x -2, find f (3)
Answer:
x= -5
Step-by-step explanation:
Replace f(x) with 3, because f(x) is a fancy way of saying y. The equation is 3=-x-2. Add 2 to both sides to isolate the variable. You get 5=-x. Divide -1 from both sides to further isolate the variable. You get -5=x.

a total of 60 boys and girls attended a basketball game. there were twice as many girls at the game as there were boys. how many boys were at the game?
Answer:
20 boys
Step-by-step explanation:
Variables: g = girls; b = boys
Step 1: set up basic equation
60 = g + b
Step 2: define variable
g = 2b
Step 3: replace variable in the equation
60 = 2b + b
Step 4: solve
60 = 3b
60/3 = b
20 = b
Answer:
The Answer Is 30
Step-by-step explanation:
There were 60 boys and girls and twice as many girls were there, 30 x 2 = 60 :0
