The perimeter of a square is 56 cm. What is the Area of the square in square centimeters?
Answer:
[tex]{ \tt{let \: one \: side \: be \: s}} \\ { \bf{perimeter = 4s}} \\ 56 = 4s \\ s = \frac{56}{4} \\ { \tt{s = 14 \: cm}} \\ \\ { \bf{area = {s}^{2} }} \\ = {14}^{2} \\ { \boxed{ \tt{area = 196 \: {cm}^{2} }}}[/tex]
Answer:
A =196 cm^2
Step-by-step explanation:
The perimeter of a square is
P = 4s where s is the side length
56 = 4s
Divide by 4
56/4 = 4s/4
14 =s
The area is given by
A =s^2
A =14^2
A =196 cm^2
a 20 foot ladder leans against a building. if the ladder is 8 feet from the building, find to the nearest degree, the measure of the angle that the foot of the ladder makes with the ground
Answer:
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos theta = 8/20
cos theta = 2/5
Taking the inverse cos of each side
cos^-1 (cos theta) = cos ^-1 ( 2/5)
theta =66.42182152
To the nearest degree
theta = 66 degrees

A very important enzyme your body produces when you are scared is adrenaline, 2C9H13NO3. How many hydrogen atoms are represented in the adrenaline formula? pls someone anwser quick
Answer:
26 hydrogen atoms
Step-by-step explanation:
Let us look at the formula presented for Adrenalin carefully. We will discover that the formula written there is 2C9H13NO3.
This means that that's there are 18 carbon atoms, 26 hydrogen atoms 2 nitrogen atoms and 6 oxygen atoms in the formula shown above.
This is so because the 2 written before the symbols of the elements must multiply the subscript of each element in order to obtain the number of atoms of that element present in the compound as shown.

4+2(x–4)=–7(x+7)
....Whats the answer? NEEDED ASAP
Answer:
-5
Step-by-step explanation:
4+2(x-4) = -7(x+7)
First, work out parenthesis: 4+ 2x-8 = -7x -49
Combine like terms: 2x-4= -7x-49
now isolate x by first adding 49 to each side: 2x+45= -7x
Then subtract 2x from each side: 45= -9x
Last, divide both sides by -9:
x= -5
Answer:
The answer is negative five or -5.
Step-by-step explanation:
First, you need to distribute your equation and at the end, the -4 should be just 2x - 8.
Second, subtract the numbers 4 and -8, which will equal to -4.
Third, rearrange your terms. Those terms would be -4 + 2x, so it should be 2x - 4.
Fourth, distribute again but with -7(x + 7) and you should get -7x - 49.
Fifth, add four to both sides of your equation. It should be like 2x - 4 + 4 = -7x - 49 + 4.
Sixth, add the numbers for the both sides. Therefore, you have 2x = -7x - 45.
Seventh, add 7x to both sides of the equation. You add it to 2x and -7x - 45 + 7x.
Eighth, simplify by combining like terms which you get 9x = -45.
Ninth, divide both of the sides of your equation by the same term. Your number to use when diving is 9.
Tenth, simplify but cancel terms that are both the numerator and denominator. Then you divide the numbers and get -5.

Answer:
x=8
Step-by-step explanation:
The angles shown are vertical angles and vertical angles are equal
13x+19 = 16x -5
Subtract 13x from each side
13x-13x+19 = 16x-13x -5
19 = 3x-5
Add 5 to each side
19+5 = 3x-5+5
24 = 3x
Divide by 3
24/3 = 3x/3
8 = x
Answer:
x = 8
Step-by-step explanation:
The angles shown are vertical angles
Vertical angles are congruent
Hence, 13x + 19 = 16x - 5
We now solve for x using the equation we just created
13x + 19 = 16x - 5
Subtract 13 x from both sides
19 = 3x - 5
Add 5 to both sides
24 = 3x
Divide both sides by 3
x = 8

Answer: B. DBC
Step-by-step explanation:
Answer: [tex]\angle DBC[/tex] (choice b)
================================================
Explanation:
When naming any angle, you need 3 points. The middle point is the vertex of the angle. The other two points can be in any order as long as they are on the lines or rays that we want.
We go for angle DBC, which we can write as [tex]\angle DBC[/tex], since B is at the vertex and points D and C are on either side of the vertex.
Angle ABD is adjacent to the marked angle, but it's not what we're after.
Angle BDC isn't drawn, so we cross this off the list as well.
Saying [tex]\angle B[/tex] is too vague in this context because it could mean either [tex]\angle ABD[/tex] or it could mean [tex]\angle DBC[/tex] since they both share the same vertex B.
Graph the solution set to this inequality.
3x – 11 > 7x + 9
Step-by-step explanation:
Solve the inequality:
[tex]3x - 11 > 7x + 9[/tex]
Rearrange unknown terms to the left side of the equation:
[tex]3x - 7x > 9 + 11[/tex]
Combine like terms:
[tex] - 4x > 9 + 11[/tex]
Calculate the sum or difference:
[tex] - 4x > 20[/tex]
Reduce the greatest common factor for both sides of the inequality:
[tex] - x > 5[/tex]
Divide both sides of the inequality by the coefficient of variable:
[tex]x < - 5[/tex]
2: plot:
[tex]x < - 5[/tex]
Graph on number line:
The solution inequality that represents the solution of the given expression inequality is → x < - 5.
What is inequality? Differentiate between equation and expression? expression inequality : An inequality is used to make unequal comparisons between two expressions or numbers.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the inequality as follows -
3x – 11 > 7x + 9
The inequality is given as -
3x – 11 > 7x + 9
3x > 7x + 9 + 11
3x - 7x > 9 + 11
- 4x > 20
x < - 5
Therefore, the solution inequality that represents the solution of the given expression inequality is → x < - 5.

What is the slope of the line 3x -9y =4?
Answer:
1/3
Step-by-step explanation:
3x -9y =4
To find the slope get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
Subtract 3x from each side
-9y = -3x+4
Divide each side by -9
-9y/-9 = -3x/-9 +4/-9
y = 1/3x -4/9
The slope is 1/3 and the y intercept is -4/9
Here,
3x -9y =4
To find the slope get the equation in slope intercept form ( y= mx+b where m is the slope and b is the y intercept)
Subtract 3x from each side
-9y = -3x+4
Divide each side by -9
-9y/-9 = -3x/-9 +4/-9
y = 1/3x -4/9
The slope is 1/3 and the y intercept is -4/9

Answer:
bro/sis through this solution u can solve ur values
Step-by-step explanation:
To calculate the variance, you first subtract the mean from each number and then square the results to find the squared differences. You then find the average of those squared differences. The result is the variance. The standard deviation is a measure of how spread out the numbers in a distribution are.

Answer:
The difference is 3 for 4-7, and 39 for 52-91. So basically its a change of 3 for every 4-7 I think this is what you ask for. Let me explain and show results and then pick what you need.
Step-by-step explanation:
So, we know 4 to 7 is 3.
52 to 91 is 39.
So one is a change in 3. the other is a change is 39.
However, could these be the same, just bigger?
Lets divide the 52 to 91 with a change of 39 by 4 to 7 with a change of 3:
52/4 to 91/7 with a change of 39/3 =
13 to 13 with a change of 13.
So this tells us that the 52 to 91 with a chang eof 3 is 13 times bigger than 4 to 7 with a change of 3.
Hope this helps!

The function f(x) = 2^x - 1 is transformed to function g through a horizontal shift of 7 units left. What is the equation of function g?
Replace the values of hand kin the equation.
Answer:
h = 7, k = -1
Step-by-step explanation:
g(x) = f(x + 7)
g(x) = 2(x + 7) - 1
g(x) = 2(x + h) + k
h = 7, k = -1
Answer:
h=7 and k=-1
Step-by-step explanation:
Remember that the values of h and k represent horizontal and vertical shifts respectively. Therefore, because the transformation is a horizontal shift of 7 units to the left, then h=7 and k=-1.
Review the graph to observe the transformation
