Edith compra un kiligramo de jitomate de a $7.50;4 kilogramos de papa de $ 9.20 el kilogramo y 2 kilogramo de cebolla de $ 6.40 el kilogramo ¿Cuánto pagara en total?

Edith pagará $57.10 en total por su compra.

Step-by-step explanation:

Dado que Edith compra un kilogramo de jitomate de a $7.50; 4 kilogramos de papa de $9.20 el kilogramo y 2 kilogramo de cebolla de $6.40 el kilogramo, para determinar cuánto pagara en total se debe realizar el siguiente cálculo:

1 x 7.5 + 4 x 9.2 + 2 x 6.4 = X

7.5 + 36.8 + 12.8 = X

44.3 + 12.8 = X

57.1 = X

Por lo tanto, Edith pagará $57.10 en total por su compra.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
