Firstly, $3.99 × 5 = $19.95
Second, $2.75 × 5 = $13.75
Third, $2.70 × 3 = $8.1 (Since it is just $8.1 that won't make sense so we'd add a 0 so It's $8.10.)
Then we do the last one which is 13 × $0.89 = $11.57.
So now since we are done multiplying we can add it all up.
The answer is $53.37 when we finish adding it up.
and I don't know what A number sentence is sorry :(
I took a long time typing this :< I hope this helps though! :D
(9 - 7 × 3 + 4)²
(9 - 21 + 4)²
(9 - 17)²
(-12)²
144
(-2,8),(-1,5),(0,2),(1,-1),(2,-4) are points of the line.
Answer:
90 degrees
Step-by-step explanation:
A rhombus has 4 congruent sides, which means that if the cross each crossing part is 90 degrees
The perimeter of the square is:
ft
Step-by-step explanation:
The picture is attached with the answer.
the diagonal of a square divides it into two right angled-triangles.
We can use one of the triangle to find the length of side as the diagonal will be the hypotenuse of the triangle
Let a be the side of the square, then according to Pythagoras theorem

Dividing both sides by 2

Taking Square root on both sides

Now,

Hence,
The perimeter of the square is:
ft
