Miss silver order five pizza for every 20 students working on the campus clean up how many pizzas should she order if 36 students participate how many pizzas should she order if 48 students participate

Step-by-step explanation:

Miss silver ordered five pizza for every 20 students working on the campus clean. This means that the number of pizzas that she ordered for 1 student would be

5/20 = 1/4 pizza per student

if 36 students participate, the total

number of pizzas that she would order would be

36 × 1/4 = 9 pizzas

if 48 students participate, the total

number of pizzas that she would order would be

48 × 1/4 = 12 pizzas

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.

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
