The perimeters of two squares in the model are given. Find the perimeter of the third square. P=12 units p=16 units
Answer:
20 units
Step-by-step explanation:
1) find the side of the first square
side = P / 4 = 12:4 = 3 units
2) find the side of the second square
side = P / 4 = 16 : 4 = 4 units
3) use the Pythagorean theorem to find the hypotenuse of the right triangle
[tex]\sqrt{4^2 + 3^2} = \sqrt{16 + 9} = \sqrt{25} = 5[/tex] units
4) find the perimeter of the third square
P = side x 4 = 5 x 4 = 20 units
Answer:
20 units

good luck in your exam!Practice question — Given the trapezoid to the right find the length of legs in the following isosceles trapezoid
Given:
A figure of an isosceles trapezoid with bases 18 and 24, and the vertical height is 4.
To find:
The legs of the isosceles trapezoid.
Solution:
Draw another perpendicular and name the vertices as shown in the below figure.
From the figure it is clear that the AEFD is a rectangle. So,
[tex]EF=AD=18[/tex]
Since ABCD is an isosceles trapezoid, therefore in triangle ABE and DCF,
[tex]AB=DC[/tex] (Legs of isosceles trapezoid)
[tex]AE=DF[/tex] (Vertical height of isosceles trapezoid)
[tex]m\angle AEB=m\angle DFC[/tex] (Right angle)
[tex]\Delta ABE\cong \Delta DCF[/tex] (HL postulate)
[tex]BE=CF[/tex] (CPCTC)
Now,
[tex]BE+EF+FC=BC[/tex]
[tex]2BE+18=24[/tex]
[tex]2BE=24-18[/tex]
[tex]2BE=6[/tex]
[tex]BE=3[/tex]
Using Pythagoras theorem in triangle ABE, we get
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
[tex](AB)^2=(AE)^2+(BE)^2[/tex]
[tex](AB)^2=(4)^2+(3)^2[/tex]
[tex](AB)^2=16+9[/tex]
[tex](AB)^2=25[/tex]
Taking square root on both sides, we get
[tex]AB=\pm \sqrt{25}[/tex]
[tex]AB=\pm 5[/tex]
Side length cannot be negative. So, [tex]AB=5[/tex].
Therefore, the length of legs in the given isosceles trapezoid is 5 units.
Find the value of z in rhombus ABCD.
Mr. Tan bought a mobile phone at a discount of 25 %. The original price of mobile phone was of $400. How much did he pay for the mobile phone.?
Answer:
$300
Step-by-step explanation:
$400 is 100% of the price
25% is a quarter of 100%
A quarter of 400 is 100 so the discount was $100
400-100 =300

What is the value of x in the equation −8 + x = −2?
Will mark brainliest if done within 20 minutes of this being posted! NO LINKS NO FILES. Solve the radical equations and show your work, check your solutions too.
Step-by-step explanation:
5√x+3 = -20
÷5. : √x+3 = -4
square: x+3 = 16
-3: x = 13
√x+18 -2 = x -4
+2 : √x+18 = x -2
square: x+18 = x^2 - 4x +4
-18: x = x^2 -4x -14
-x : 0 = x^2 -5x - 14
foil: (x- 7) (x+2) = 0
x = 7, -2
During a blind taste test of 8 different
sodas, some people were asked to choose
a favorite. Each dot represents one person.
Taste Test
.
A
B

F
G
H
D E
Soda
If the ratio of people choosing B to people
choosing H stays the same, how many
people will choose H if the number of people
who choose B increases to 20?
F 6
G4
H5
J 3
Answer:
the answer is 5
Step-by-step explanation:
the ratio is 4:1 so if you increase B to 20 you divide by 4 to get 5.
20:5=4:1

I really need help on this question, because I forgot of how to find the angle of each variable.
Answer:
a = 38 degree
b = 54 degree
c = 54 degree
Step-by-step explanation:
a = 180 - 142 = 38 ( angle on a straight line is equal to 180)
To determine the value of b, we have to find the other missing angle in the triangle.
the value of the missing angle is 38
Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38
b = 180 - (38 + 88) = 54
c = 54
the stove you have to bake in is an old one and only has the temperature in ° Fahrenheit. You are making rusks and have to dry them overnight at a temperature of 176°.Convert this temperature to ° Celsius
Answer:
[tex]80^{\circ} C[/tex]
Step-by-step explanation:
You are making rusks and have to dry them overnight at a temperature of 176° F.
The given temperature is in Fahrenheit. We need to convert it into °C.
The relation between Fahrenheit and °C is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex]
Put F = 176
So,
[tex]C=\dfrac{5}{9}(176-32)\\\\C=\dfrac{5}{9}\times 144\\\\C=80^{\circ} C[/tex]
So, the temperature is equal to [tex]80^{\circ} C[/tex].

what is -2.3 -1.2
explain your answer
Answer:
-2.3 - 1.2 = -3.5
Step-by-step explanation:
when we’re doing negative adding means subtracting so what I idi was add 2.3 and 1.2 and I got 3.5 so I think what number is bigger it’s -2.3 so since it’s negtive I put a negative that’s how I got it
Slope is written as a ratio of the vertical change (run) to the horizontal change (rise) between any two points on a line.
Answer:
Step-by-step explanation:
Yeah the equation is change in y over change in x; change in is represented with the delta sign, so y2-y1/x2-x1
Sonia walks to her aunt's house. She leaves home at 1025. She walks a total of 12km at an average speed of 5km/h. Work out the time Sonia arrives at her aunt's house.
Answer: 1249 hrs
Step-by-step explanation:
Sophia walked for 12 km to get to her aunt's house.
She did this at a speed of 5km/h which means that the time taken was:
Time = Distance / Speed
= 12 / 5
= 2.4 hours
2.4 in hours:
= 0.4 * 60 minutes
= 24 minutes
= 2 hours 24 minutes
If she left at 1025, she would arrive at:
= 1025 + 2 hours 24
= 1249 hrs

if john wallked 50 miles than mira,how many miles do you think mira walked if they both walked a total of 290 miles.
Answer:
Mira = 95 miles
Step-by-step explanation:
Given
John walked 50 miles than Mira
The total miles walked is 290
To find
If John walked 50 miles more than Mira and the total miles walked including Mira is 290, then divide 290 by both of them. Once that is done, don't evenly distribute the miles to them. Because remember, John walked 50 miles more than Mira. So we just distribute this with John having 50 miles more. By subtracting 50 from Mira's share and give it to John
Solve
Divide 290 by 2290 ÷ 2 = 145
Subtract 50 from Mira's share and give it to JohnMira's 145 - 50 = 95
Add that 50 to John's 145John's 145 + 50 = 195
Therefore, John ran 195 miles and Mira ran 95 miles.
