A 15 feet ladder leans against a wall at 52o. How far from the wall is the foot of the ladder?
Answer:
Step-by-step explanation:
"A fifteen-foot ladder leans against a wall at 52°."
Do you mean that the ladder makes a 52° angle with the wall?
x = distance between foot of ladder and base of wall
sin(52°) = x/15
x = 15sin(52°) ≅ 11.82 ft
Or, did you meant that the ladder makes a 52° angle with the ground?
cos(52°) = x/15
x = 15cos(52°) ≅ 9.23 ft
There are 350 students at a middle school dance, where ratio of 7th graders to 8th graders is 3:4 how many of the students at the dance are 8th graders?
Answer:
150 7th Graders and 200 8th graders
Step-by-step explanation:
Basically, add the parts of the ratio together and create 7. Then, to find out how much 1 part is equal to, divide the amount of students by the number of parts - so it would be like 350/7 = 50.
So now you know that 1 part is equal to 50 students. From here, you can multiply the two amounts of parts by 50.
3 x 50 = 150 7th Graders
4 x 50 = 200 8th Graders

3. What three numbers are the Pythagorean triple generated by using 4 for x and 1 for y. Remember to use the formulas:
a = x2 - y2, 6 - 2xy, and C = x2 + y2
O 6, 8, and 10
O 5, 11, and 12
O 8, 15, and 17
O 3, 5, and 8
Given:
Consider the three number are given by:
[tex]a=x^2-y^2[/tex]
[tex]b=2xy[/tex]
[tex]c=x^2+y^2[/tex]
To find:
The three numbers are the Pythagorean triple generated by using 4 for x and 1 for y.
Solution:
We have,
[tex]a=x^2-y^2[/tex]
[tex]b=2xy[/tex]
[tex]c=x^2+y^2[/tex]
Substituting 4 for x and 1 for y, we get
[tex]a=4^2-1^2[/tex]
[tex]a=16-1[/tex]
[tex]a=15[/tex]
Similarly,
[tex]b=2(4)(1)[/tex]
[tex]b=8[/tex]
And,
[tex]c=4^2+1^2[/tex]
[tex]c=16+1[/tex]
[tex]c=17[/tex]
The three three numbers are the Pythagorean triple are 8,15 and 17.
Therefore, the correct option is C.

Answer:
(-4, -1) (see below)
Step-by-step explanation:
Substitution means that you actually replace, or "substitute," the value of the variable in.
Here, y = -1, so -3x - 8y = 20 can be written as:
-3x - 8 (-1) = 20
We can now solve for x:
-3x + 8 = 20
-3x = 12
x = -4
Putting this into (x, y) format equals:
(-4, -1)
How do you solve the following equation
: X/-3 + 2=4
Answer:
For this equation you be inverse operation giving you the answer -6
further information down below :)
Step-by-step explanation:
Your goal for this is to isolate the variable which is x.
First, find the operation opposite of addition which is subtraction
When you add that operation to both sides with the constant(2)
2 and 2 cancel each other out, but to the for the term(4) 4-2=2
after that you have your new term which is x/-3=2
You do the same thing but to in division because the opposite of multiplication is division in this case you multiply -3 to both sides -3*-3 cancel each other out, now you have-3*2= negative times a positive equal negative in anyway so, overall you get -6.
To check:
you do the full equation now that you have isolated the variable, you now can do the operations normally which are. -6/-3=2 because when you divide a negative by a negative you get a positive end out with 2+2=4 which is correct and match the sum.
This means that our answer is correct :)
Each peanut butter snack costs $2. Each chocolate snack costs $3. How much does it cost to buy 6 peanut butter snacks and 8 chocolate snacks? Write an equation.
Answer:
36
Step-by-step explanation:
8x3 is 24
6x2 is 12
when you add those together you get 36
Answer:
2 dollars x 6 Peanut butter snacks= 12 total
3 dollars x 8 chocolate= 24 total
24+12= 36 for the total all together
Step-by-step explanation:
You are buying 6 peanut butter snacks and they are $2 each so you multiply those numbers together for the total of Peanut butter snacks. You are also buying 8 things of chocolate and they are $3 each multiply them together you get the total for the chocolate. if you need the total for all together you add the totals together and you have your over all answer.

Malachy was thinking of a number. Malachy divides by 2, then adds 9 to get an answer of 4. What was the original number?
Answer:
The number is -10
Step-by-step explanation:
I will answer this while I read through the question.
Let the number be x
Divide by 2
[tex]\frac{x}{2}[/tex]
Add 9 to it
[tex]\frac{x}{2} + 9[/tex]
It gives 4
[tex]\frac{x}{2} + 9 = 4[/tex]
Now, we solve for x
Collect Like Terms
[tex]\frac{x}{2} = 4-9[/tex]

Complete the following statement. The distance around the edge of a figure is its ____.
Answer:
Perimeter
Hope it helps!
The distance around the edge of a figure is its Perimeter.
To complete the following statement. The distance around the edge of a figure is its ____.
Perimeter is the measure of the length of the figure on its circumference.
Since in the question blank, space is given following the definition,
The distance around the edge of a figure is perimeter because the measure of the boundary of any figure is termed as its perimeter.
For example, the Perimeter of the rectangle is the total measure of the two-time measures of length and width. For the Perimeter of the square, it is 4 times the length of one side. For the Perimeter of the circle, it is 2π times of radius.
Thus, the distance around the edge of a figure is its Perimeter.

Emily can walk 3/4 of a mile in 1/4 of an hour.
At this same rate, how long does it take Emily to walk 1 mile?
Answer:
20 minutes
Step-by-step explanation:
Method 1:
(0.75)/(0.25)=(1)/(x)
0.75*1.333333=1, so multiply 0.25 by 1.333333 to find the value of x!
0.25*1.333333=0.33333, or one-third of an hour, or 20 minutes.
Method 2:
(0.75)/(0.25)=(1)/(x)
Cross-multiply
0.75x=0.25
(0.25)/(0.75)=x
x=0.33333 hours
Emily will use 20 minutes or 1/3 hour to walk 1 mile.
Note that 3/4 = 0.75
1/4 hour = 1/4 × 60 = 15 minutes
Let the amount of time that it takes Emily to walk 1 mile be represented by x.
Therefore, the equation to solve the question will be:
0.75 /1 = 15/x
Cross multiply
(0.75 × x) = (1 × 15)
0.75x = 15
x = 15/0.75
x = 20
Therefore, Emily will use 20 minutes or 1/3 hour to walk 1 mile.
