Answer:
50 cm
Step-by-step explanation:
4/5 = 40/x
cross multiply
4x=200
x=50
Answer:
No
Step-by-step explanation:
plug the numbers into Pythagorean theorem
c^2 =a ^2 + b^2
28^2 = 20^2 + 19^2
784 = 400+361
784 = 761
No its not
Answer:
see explanation
Step-by-step explanation:
Since AC = BC then ΔABC is isosceles with base angles
∠BAC =∠ABC, thus
3x + x = 70
4x = 70 ( divide both sides by 4 )
x = 17.5
----------------------------------------------------
∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence
y = 70 + x = 70 + 17.5 = 87.5
The summation of the money Myla spend altogether is $41.9
As in the given problem we can see Myla bought
a shirt for $25.36 and
a hat for $5.09 and
a belt for $11.45.
Hence we need to know the cummulative price she spend altogether.
To get the total price we should add the price of shirt hat and belt.
Summing all the prices we get
$25.36+$5.09+$11.45=$41.9
As all the quantities are given in one currency thus we can add them by simple addition formula.
Thus she spend $41.9 altogether at the mall.

Answer:
86.9 cm^3
Step-by-step explanation:
You have to find the area of every face. Since the opposite sides have the same area, you can find three areas and then multiply by 2.
2(5.3x2)=21.2
2(4.5x2)=18
2(4.5x5.3)=47.7
You then add the values together...
21.2+18+47.7=86.9
