ft What is the area of one square?
Answer:
area= length×width
since it is a cube or in this case, a square all sides are the same. meaning all sides are 2ft. now you must multiply 2ft×2ft= 4ft inside. the area is 4ft
Answer:
If a square has one side of 4 inches, the area would be 4 inches times 4 inches, or 16 square inches.

The Johnson family pays $19.75 at the game for 3 ice cream cones and 4 funnel cakes. The Duke family pays $35.25 at the same game for 5 ice cream cones and 8 funnel cakes. How much does a funnel cake cost? How much does an ice cream cone cost?
Answer:
$1.75 cost of the funnel cake and $4.25 cost of the ice cream cone.
Step-by-step explanation:
x = cost of the ice cone cone
y = cost of the funnel cake
3x + 4y = 19.75 multiply (-2) ⇔ -6x - 8y = -39.50
5x + 8y = 35.25 do not change ⇔ + 5x + 8y = 35.25
-x = -4.25
x = 4.25 cost of the ice cream cone
Substitute into the second equation x = 4.25 and solve for y
5(4.25) + 8y = 35.25
21.25 + 8y = 35.25
8y = 14
y = 1.75 cost of the funnel cake

an equilateral triangle with the perimeter of 90cm, what is the length of its side?
Answer:
The length of its side is 30 cm
Step-by-step explanation:
Given:An equilateral triangle with the perimeter of 90cm.
In a Equilateral Triangle all sides are equal
i.e., all 3 sides are equal
Now,
90/3 = 30 cm
Thus, The length of its side is 30 cm

an equilateral triangle with the perimeter of 90cm, what is the length of its side?
Answer:-30cm
Explanation:-Given,
Perimeter of the equilateral triangle = 90cm
We know that,
All three sides of an equilateral triangle are equal.
So,
90/3 = 30cm
The length of the side is 30cm.
What is the slope of the line through (6,0) and (7,1)
[tex]\huge \bf༆ Answer ༄[/tex]
Let's find the slope of line passing through given points ~
[tex] \sf \dfrac{y2 - y}{x2 - x1} [/tex][tex] \sf \dfrac{1 - 0}{7 - 6} [/tex][tex] \sf \dfrac{1}{1} [/tex][tex] \sf1[/tex]Hence, slope of the line will be 1.
Answer:
1
Step-by-step explanation:
slope = (change in y)/(change in x)
slope = (1 - 0)/(7 - 6)
slope = 1/1 = 1

A car factory made 41 cars. 20 of the cars had a sunroof. What is the ratio of the number of cars without a sunroof to the number of cars with a sunroof?
Write your answer as two numbers separated by a colon (for example, 2:3).
Answer:
21:20
Step-by-step explanation:
Since there are 20 cars with sunroof
Subtract 20 from 41
and you get 21 which are the cars with no sunroof
making it 21:20
Answer: 21 : 20
Step-by-step explanation: Since the factory made 41 cars and 20 of them had a sunroof that means x = 41 -20. So 41 - 20 = 21 cars without sunroof. They ask to put the ratio with cars without sunroof first then cars with a sunroof so it would be 21 : 20.
(x = cars without sunroof)

[tex]x(x-2)+3(x-2)=0[/tex]
Answer:
x = -3 or x = 2
Step-by-step explanation:
Given that,
x ( x - 2 ) + 3 ( x - 2 ) = 0
( x + 3 ) ( x - 2 ) = 0
So,
( x + 3 ) = 0 ( x - 2 ) = 0
x + 3 = 0 x - 2 = 0
x = 0 -3 x = 0 + 2
x = (-3) or x = 2

no solution
one solution
infinite solutions
two solutions
Answer:
t = 12.5
