The area of a square is 100 square inches. What is the perimeter of this square?
a. 40 inches
b. 20 inches
c. 10 inches
Answer:
40inches
Step-by-step explanation:
If the area is 100 square inches, therefore on side of the area is just the square root of the area that is 10. Bcuz 10 x 10 =100 Square inch right? So one side is 10. A square has 4 sides, so multiply 10 by 4, u get 40inches
Answer:
40 inches
Step-by-step explanation:
Try finding length first.
Area of square = 100 square inches
or, l square= 100 square inches[ using formula]
or, l=10 inches
Hence, length( l ) = 10 inches
Perimeter of square= 4l
= 4×10 inches
= 40 inches

An athlete runs two miles in 13.5 minutes. How many minutes is this per mile?
Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile
The sides of a triangle are in the ratio of 5:12:13. If it's permiter is 150cm,fine the area of the triangle
Answer:
495cm^2
Step-by-step explanation:
First of all get the total ratio which is (5+12+13)=30 then use it to find the length of each side that is to say
EACH SIDE RESPECTIVELY AS PER THE RATIO
side 1
(5/30) × 150cm = 25cm
base
(12/30) × 150cm = 60cm
side 2
(13/30) × 150cm = 65cm
My triangle will have one side 25cm, side one 65cm and the base 60cm then you are going to use pythagoras theorem to find out the height of the triangle using the formula
a^2 + b^2 = c^2
the height will be 'a', 25cm will be 'b' then inorder to create a right angle we will divide the baseinto two that is to say (60cm / 2= 30cm) therefore the 30cm will be 'c'
In conclusion
HEIGHT
= a^2 + (25cm)^2 = (30cm)^2
= a^2 + (25cm × 25cm) = (30cm × 30cm)
= a^2 + 625cm^2 = 900cm^2
= a^2 = 275cm^2
= √a^2 = √275cm^2
= a = 16.5cm
therefore the height is 16.5cm
AREA
Height = 16.5cm
Total base = 60cm
Area = 1/2 × basearea × height
= 1/2 × 60cm × 16.5cm
= 495cm^2

O A. The solution is
(Simplify your answer.)
B. The solution is all real numbers,
O C. There is no solution,
(Answer quickly)
Answer:
➣ C. There is no solution
Step-by-step explanation:
[tex]6\left(x+4\right)=5\left(x-5\right)+x[/tex]
Apply distributive law:-
[tex]=6x+6\cdot \:4[/tex]
➠ Now, Multiply:- 6 × 4= 24
[tex]6x+24[/tex]
[tex]5\left(x-5\right)+x[/tex]
[tex]=5x-25[/tex]
[tex]=5x-25+x[/tex]
➠ Group like terms:-
[tex]=6x-25[/tex]
Now, we have...
[tex]6x+24=6x-25[/tex]
➠ Subtract 24 from both sides:-
[tex]6x+24-24=6x-25-24[/tex]
[tex]6x=6x-49[/tex]
➠ Now, Subtract 6x from both sides:-
[tex]6x-6x=6x-49-6x[/tex]
[tex]0=-49[/tex]
Here, the sides are not equal so there is no Solution

A. 1 2/3
B. 1 5/6
C. 2 5/6
D. 3
ANSWER
First of all I turn the fractions back to their improper form that is to say;
6 3/4 - 4 11/12
= 27/4 - 59/12
after that I get the LCM of 12 and 4 which is 12
= (²⁷/⁴ × 12) - (⁵⁹/¹²× 12) /12
= (81 - 59) /12
= 22\12
since the answer is requested for in the simplest form the the difference in form of a mixed fration is 1 10/12 which is reduced to 1 5/6 therefore the answer is 'B'
4 b. An airplane flies with a constant speed
of 760 km/h. How far can it travel in
33 minutes?
Answer: 418 km
Step-by-step explanation:
I would start this question by finding how far it can travel in one minute. To find this you divide 760/km by 60, which would be 12 [tex]\frac{2}{3}[/tex]/minute.
Next to find 33 minutes, you simply multiply 12[tex]\frac{2}{3}[/tex] by 33, which is 418.
Therefore, the airplane can travel 418 km in 33 minutes.
Divide the speed per hour by 60 and then multiply the answer by 33 to get the distance travelled
Referring to the figure, find the value of x
Answer:
x + (x-73) + 67 = 180
x + x - 73 +67 = 180
2x - 6 = 180
2x = 180 + 6
x = 186 / 2
x = 93
Step-by-step explanation:
x-73+x+67=180(sum of angles in a triangle )
2x-6=180
2x=180+6=186
x=186/2
x=93
