Explaining the Concept:
To get the perimeter of this square, we will first get the value of one side
Since all the sides of a square are equal, we will find the length of one of the side from the triangle EOF
Finding the length of one side of the triangle:
In triangle EOF:
Using the pythagoras's theorem
EO²+OF² = EF²
(5)² + (5)²= side² [since EF is a side of the square]
side²= 50
side = √50
side = 5√2 units
Perimeter of the Square:
We know that the perimeter of a square is 4 times its side
Perimeter = 4 * side
Perimeter = 4 * 5√2
Perimeter = 20√2 units

Answers
Answer:
130
Step-by-step explanation:
You can make a ratio - 325:5, then we can simplify it to 65:1, where we are comparing # of beats in 1 minute. Now, we can just multiply both sides by two, getting us 130:2, which is just 130 beats.
if 1/4 inch on a map represents 50 miles then what is the number of miles represented by 2 7/8 inches
Answers
Answer:
575
Step-by-step explanation:
First, divide 2 7/8 by 1/4. This gives you 11.5. Then, multiply 50 by 11.5, giving you 575.
The number of miles represented by [tex]2\frac{7}{8}[/tex] inches is 575 miles.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, 1/4 inch on a map represents 50 miles.
So, 1 inch is represented by
= 50÷1/4
= 50×4
= 200 miles
The number of miles represented by [tex]2\frac{7}{8}[/tex] =23/8 inches
23/8 ×200
= 23×25
= 575 miles
Therefore, the number of miles represented by [tex]2\frac{7}{8}[/tex] inches is 575 miles.

wheelchair ramp forms 20° angle with the ground. If the length of the ramp to the porch is 21.5 feet, how high (H) off the ground is the porch?
Answers
Answer:
The porch is 7.35 feet off the ground
Step-by-step explanation:
Trigonometric Ratios
The ramp, the height of the porch, and the distance from the base of both form a right triangle where trigonometric ratios can be applied.
The angle of 20° has the height of the porch H as the opposite side, and the hypotenuse is the length of the ramp.
The sine is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
For our problem:
[tex]\displaystyle \sin 20^\circ=\frac{H}{21.5}[/tex]
Solving for H:
[tex]H=21.5\cdot \sin 20^\circ[/tex]
Find the sine of 20° by using a calculator:
[tex]H=21.5\cdot 0.342[/tex]
H=7.35 feet
The porch is 7.35 feet off the ground

The vertex of a parabola is (6,2), and the equation of its directrix is x = 8. What is the equation of this parabola in standard form?
a. (y−2)2=8(x−6)
b. (y−2)2=−8(x−6)
c. (x−6)2=−8(y−2)
d. (x−6)2=8(y−2)
Answers
Answer:
The equation of this parabola in standard form is (y - 2)² = -8(x - 6) ⇒ B
Step-by-step explanation:
Let us revise the standard form of the equation of a parabola
The standard form of the equation is (y - k)² = 4p(x - h), where
(h, k) is the turning point (h + p, k) are the coordinates of the focus x = h - p is the equation of the directrix
∵ The vertex of a parabola is (6, 2)
→ From the fact above
∴ h = 6 and k = 2
∵ The equation of its directrix is x = 8
→ From the fact above
∴ h - p = 8
→ Substitute the value of h to find p
∵ 6 - p = 8
→ Subtract 6 from both sides
∴ - p = 2
→ Multiply both sides by -1
∴ p = -2
→ Substitute the values of h, k, and p in the form above
∴ (y - 2)² = 4(-2)(x - 6)
∴ (y - 2)² = -8(x - 6)
∴ The equation of this parabola in standard form is (y - 2)² = -8(x - 6)

A sum of money is shared between two people in the ratio 19:14. If the first person receives 38 LE, how much money does the other receive?
Answers
Answer:
28 LE.
Step-by-step explanation:
Ratio Question:
The ratio of the money spent is 19/14. So you can create this equation:
19/14=38/x
Since they are the same ratio, this means that 38/x would equal 19/14.
Multiply both sides by 14 and x:
19x=532
532/19=x
x=28

If C is the midpoint of BD, what is the coordinate of point C if point B is at 0?
Answers
Answer:
It depends on where point D is placed so C > 0
Step-by-step explanation:
As i said above
We want to find the coordinate of C given that it is the midpoint of BD.
We know that B is at 0, so we can assume that each letter represents a position on the number line.
Then we can assume that D is located at a number different than zero, let's assume that D is located at the value d.
Then the segment BD goes from 0 to d, so its length is d.
Then the midpoint is at the middle, at d/2 plus the smallest value, 0:
C = d/2 + 0 = d/2

if z is the circumcenter of triangle qrs find each measure
Answers
Answer:
Step-by-step explanation:
Circumcenter of A triangle is the center of a circle passing through the vertices of the given triangle.
So, the distance of Z from the vertices Q, R and S will be the radii of the circle.
Therefore, ZQ = ZR = ZS
Since, circumcenter of a triangle is defined by the point of intersection of the perpendicular bisectors of the sides of the given triangle.
Therefore, points W, X and Y are the midpoints of sides QR, RS and QS.
Using these facts,
a). QR = 2(WQ)
= 2(25)
= 50
b). Apply Pythagoras theorem in ΔRXZ,
(RZ)² = (RX)² + (ZX)²
(RZ)² = (40)² + (9)²
RZ = √1681 = 41
c). XS = [tex]\frac{1}{2}(RS)[/tex]
= [tex]\frac{1}{2}(80)[/tex]
= 40
d). Since, ZQ = ZR = ZS
ZS = 41
e). By applying Pythagoras theorem in ΔRWZ,
(RZ)² = (WZ)² + (WR)²
(41)² = (WZ)² + (25)²
(WZ)² = (41)² - (25)²
WZ = √1056
WZ = [tex]4\sqrt{66}[/tex]
≈ 32.5
Applying the circumcenter theorem and the Pythagorean Theorem, the following measures are calculated as:
a. QR = 50
b. RZ = 41
c. XS = 40
d. ZS = 41
e. WZ = 32.5
Based on the circumcenter theorem of a triangle, the following holds true given that Z is the circumcenter of triangle QRS:
RZ, QZ, and ZS are equal (circumcenter Z is equidistant from the three vertices of ΔQRS).The perpendicular bisectors divides the three sides, RS, QS, and QR into equal parts each.Points X, Y, and W are at right angles.Given:
RS = 80WQ = 25XZ = 9a. Find QR:
QR = 2 × WQ = 2 × 25
QR = 50
b. Find RZ in right ΔXRZ:
XZ = 9 (given)
XR = 1/2(RS) = 1/2(80) = 40
Apply Pythagorean Theorem to find RZRZ = √(XZ² + XR²)
SubstituteRZ = √(9² + 40²)
RZ = 41
c. Find XS:
XS = 1/2(RS) = 1/2(80)
XS = 40
d. Find RZ:
RZ = ZS = QZ = 41 (equidistant)
ZS = 41
e. Find WZ in right ΔWRZ:
WR = WQ = 25
WR = 25
RZ = 41
Apply Pythagorean Theorem to find WZWZ = √(RZ² - WR²)
SubstituteWZ = √(41² - 25²)
WZ = 32.5

A movie theater currently seats 400 people.
After a renovation, the movie theater will have larger
seats, so it will only be able to seat 320 people.
What is the percent decrease in the number of seats? ,, i need help asap.
Answers
Answer: 20%
Step-by-step explanation: As a fraction, the decrease would be 80/400 as we should know. To find the percentage, you put 80/400 in simplest form which 1/5. And since a fraction is a division problem and you want to find the answer as a percentage, you divide 1 by 5 and get 0.20. To convert a decimal into a percentage, multiply the decimal by 100. This means move the decimal space twice to the right and put a % to get 20%.

6.8x+9.3= -9.4+3.4(2-5x)
Answers
Answer: the answer to this is x=0.5
Step-by-step explanation:
In order to solve this you have to combine the multiplied terms into a single fraction so its going to look like this - 34x/5 + 9.3= -9.4+3.4(2-5x)
The reposition your terms and put together your multiplied terms into a fraction,Once you have that done distribute them
Subtract 9.3 on both sides.you may simplify and then multiply all the terms with the same value to get rid of the denominators from the fractions
also add 85x to both sides then finally divide both side by the same term which get you -59.5/119 and then simplify and you get -0.5
so x= -0.5
Answer:
x=-0.5
Step-by-step explanation:
step 1
6.8x+9.3=-9.4+3.4(2-5x)
6.8x+9.3=-9.4+(3.4)(2)+(3.4)(-5x) distribute
6.8x+9.3=-9.4+6.8+-17x
6.8x+9.3=(-17x)+(-9.4+6.8) combine like terms
6.8x+9.3=-17x+-2.6
6.8x+9.3=-17x-2.6
step 2
add 17x to both sides.
6.8x+9.3+17x=-17x2.6+17x
23.8x+9.3=-2.6
step 3
subtract 9.3 from both sides.
23.8x+9.3-9.3=-2.6-9.3
23.8x=-119
step 4
divide both sides by 23.8
23.8x/23.8= -11.9/23.8
The answer is =-0.5
