What percent of 56 is 21?
A: 3/8%
B: 3 3/4%
C: 37 1/2%
D:375%
Answer:
[tex]37\frac{1}{2}[/tex]
Step-by-step explanation:
let x be the percent
Now we have
x% of 56=21
x/100=21/56
x=100x21/56
x=[tex]31\frac{1}{2}[/tex]%
The percent of 56 that is equal to 21 is 37 1/2% by setting up a proportion and solving the equation. This means that 37 1/2% of 56 is equal to 21.
To find the percentage, we can set up a proportion. Let x represent the unknown percentage:
x/100 = 21/56
To solve for x, cross-multiply:
56x = 100 * 21
56x = 2100
Divide both sides of the equation by 56 to isolate x:
x = 2100/56
Simplifying the fraction, we get:
x = 37 1/2%
Therefore, the answer is option C: 37 1/2%.
To find the percentage of 56 that is equal to 21, we can set up a proportion between the unknown percentage and the given values. The proportion is x/100 = 21/56. Cross-multiplying and solving the equation yields x = 37 1/2%. This means that 37 1/2% of 56 is equal to 21.

Answer:
(a) 7.1
(b) (5/2, 3/2)
(c) 2
(d) y = -x +4
Step-by-step explanation:
(a)The length of AC is found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((5 -(-2))² +(-1 -0)²) = √(49 +1) = 5√2 ≈ 7.1
The length of AC is about 7.1.
__
(b)The midpoint has coordinates that are the average of the end point coordinates.
midpoint BC = (B + C)/2 = ((0, 4) +(5, -1))/2 = (5, 3)/2
midpoint BC = (5/2, 3/2)
__
(c)The slope is found using the slope formula.
m = (y2 -y1)/(x2 -x1)
For points A(-2, 0) and B(0, 4), the slope of the segment between them is ...
m = (4 -0)/(0 -(-2)) = 4/2 = 2
The slope of AB is 2.
__
(d)The slope of line BC is found in the same was as for AB.
m = (-1 -4)/(5 -0) = -5/5 = -1
The y-intercept of the line is point B, at y=4. So, the equation of line BC is ...
y = mx +b . . . . . where m is the slope, and b is the y-intercept
y = -x +4

Answer: The new point would be (2,-1)
Step-by-step explanation:
To dilate a point, you simply multiply the scale factor (1/3) by the x- and y-values of the point:
6 x 1/3 = 2
-3 x 1/3 = -1
Therefore, the new point would be (2,-1)

Which solution correctly solves the problem 5x - 16 = 79?
Answer and Step-by-step explanation:
Alright, so we have the problem 5x-16=79. First, we need to add 16 to both sides of the equation to cancel out the 16 like this:
5x - 16 = 79
+ 16 + 16
5x = 95
Now we need to divide the 5 into the 5x to cancel out the 5. This will leave us with the variable left over like this:
x = 95
5
Five can be divided into 95, so 95 divided by 5 = 19. So the answer is:
x = 19
I hope this helps.
The solution to the given equation is 19.
The given equation is 5x-16=79.
In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.
Here, 5x=79+16
5x=95
x=95/5
x=19
Therefore, the solution to the given equation is 19.

Answer:
x ≈ 33.0
Step-by-step explanation:
The third angle in the triangle is
180° - 70° - 76° = 180° - 146° = 34°
Using the Sine rule in the triangle
[tex]\frac{x}{sin76}[/tex] = [tex]\frac{19}{sin34}[/tex] ( cross- multiply )
x × sin34° = 19 × sin76° ( divide both sides by sin34° )
x = [tex]\frac{19sin76}{sin34}[/tex] ≈ 33.0 ( to the nearest tenth )
Answer:
x=33 (since it says to round it)
Step-by-step explanation:
This is an ASA triangle.
First, we need to find the value of the unlabeled angle, which is simple:
180°-70°-76°=34° Lets call that angle A
Now we use the law of sines:
x/sinX = a/sinA
x/sin76° = 19/sin34°
Then:
x = (19/sin34°) × sin76°
x = 32.968

Slope = 2; (14, 33)
Answer:
y = 2x + 5
Step-by-step explanation:
Consider the format of a line equation, y = mx + b
The slope is represented as the variable 'm.'
Since we already know that the slope is 2, we can input it into the format.
y = 2x + b
Assuming that the point (14, 33) is a point of intersection, we can input these numbers into the equation in order to find the value of b, or the y-intersect.
33 = 2(14) + b
33 = 28 + b
5 = b
2 hours before 1:40 a.m. with process
Answer:
[tex]\large\boxed{\boxed{\underline{\underline{\maltese{\pink{\pmb{\sf{\: Solution :- \: 11:30 \: p.m }}}}}}}}[/tex]
Step-by-step explanation:
The given question is to find 2 hours before 1:30 a.m.
The a.m or 'ante meridiem' & p.m or 'post meridiem'. is used in the 12 hour clock system which is a system where the 24-hours in a day is divided into 2 equal parts → a.m & p.m.
The time after 12 midnight till 12 noon is included in a.m. while the time from 12 noon to 12 midnight is included in p.m.
So, 2 hours before 1:30 a.m,
1:30 a.m - 2:00 = 11:30 p.m.This happened because, it's under the 12-hour system so, the numbers range from 1 - 12 . Since, 1:30 a.m comes somewhat towards the beginning, we have to go back 2 hours & that's 11:30 p.m.

A landscaper wants to increase the size of one of his square gardens. The garden measures 8 feet on each side. The landscaper
plans to increase each side of the garden to be 175% of its current measure.
How many square feet larger is the area of the new garden than the area of the current garden?
A. 260ft
B.160ft
C.132ft
D.48
Answer:
its c
Step-by-step explanation:
The area of the new garden will be 132ft longer than that of the current garden
Area of the squareThe formula for calculating the area of a square is expressed as:
A = L²
If the garden measures 8 feet on each side, then;
A = 8²
A = 64ft²
If the side length is increased by 175%, hence new length will be;
l = 8 + (1.75*8)
A = 14 * 14ft
A = 196 ft²
Difference = 196 - 64
Difference = 132ft
Hence the area of the new garden will be 132ft longer than that of the current garden

Consecutive integers are those that occur one after the other. Let's use 2, 3, 4 as an example.
The middle number is 3 (n). To get to 2 from 3, we need to subtract 1 (n - 1). To get to 4 from 3, we need to add 1 (n + 1).
Now that we understand how to get to each number from the middle number, we can create our expression.

She finds that when she adds a border of width one stone around the patio, the area of the border is equal
to the original area of the patio.
How many possible values for x are there?
The length of the square paving is the base unit to which the area of the
and patio and the border are evaluated.
Correct response:
The possible x-values are; 10, 6, 4, and 3Which method is used to evaluate the area of the patio?Let s represent the size of the square paving, we have;
Area of the patio = s·x × s·y = s²·x·y
New area = (2·s + s·x) × (2·s + s·y) = 4·s² + 2·s²·y + 2·x·s² + s²·x·y
Area of the border = 4·s² + 2·s²·y + 2·x·s² = s²·x·y
2·s²·(2 + y + x) = s²·x·y
2·(2 + y + x) = x·y
4 + 2·y + 2·x = x·y
x·y - 2·x = 4 + 2·y
x·(y - 2) = 4 + 2·y
Which by using gives;
