. A picnic is being planned in a school for Class VII. Girls are 60% of the total number of students and are 18 in number.
The picnic site is 55 km from the school and the transport company is charging at the rate
of Rs.12 per km. The total cost of refreshments will be Rs.4280.
a) If their first stop is at a place 22 km from the school, what per cent of the total distance
of 55 km is this?
b) What per cent of the distance is left to be covered?
c) The cost per head if two teachers are also going with the class
CBSE study 8 grade

-6 is the correct option from the above given options

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29

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.

ok then what happened.
