In a class of 30 pupils the ratio of the number of boys to the number of girls is 7 : 8. How many girls are there?
Answers
Step-by-step explanation:
let the ratio 7:8 be 7x and 8x.
now
7x+8x=30
or, 15x=30
or, x= 30/ 15
or, x= 2
here
no. of boys = 7x= 7*2 = 14
no. of girls= 8x = 8*2= 16
hope this helps u...
Answer:
16 girls
Step-by-step explanation:
sum the parts of the ratio, 7 + 8 = 15 parts
Divide the number of pupils by 15 to find the value of one part of the ratio.
30 ÷ 15 = 2 pupils ← value of 1 part of the ratio, then
8 parts = 8 × 2 = 16 ← number of girls
a polygon has 50 sides
all but one of its angle is 170 degrees
what is the size of the other angle?
Answers
Answer:
.2 degrees
Step-by-step explanation:
180-170 is 10
10/50 is .2
The size of the other angle will be 0.2 degrees.
What are polynomials?A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.
The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.
It is given that a polygon has 50 sides but one of its angles is 170 degrees.
The remaining angle will be calculated as:-
180-170 = 10
The size of the other angle is calculated below:-
Angle = 10/50
Divide the value 10 by 50 to get the angle.
Angle = 0.2
Therefore, the size of the other angle will be 0.2 degrees.

A taxi hurries for 1 hour 54min with a constant speed of 93km and then for another 5 hours 15min with a constant speed of 72km. What distance did it go
Answers
Speed = 93km /h and 72km/h
Answer: The taxi went a distance of 554.7km
Step-by-step explanation:
Speed = Distance / Time
Distance covered in the first trip = Speed x Time
Time = 1 hour 54 min =1+0.9 hours =1.9hours
=93km / h x 1.9 hours =176.7km
Distance covered in the second trip = Speed x Time
Time = 5 hours 15min = 5+0.25hours =5.25hours
=72km / h x 5.25hours =378 km
Total distance =176.7km+378 km
=554.7km

The value of the angle x is calculated as: ∠x = 64
How to find the value of the missing angle?Let the intersect of line SV and RT be Y
Sides RTU forms a triangle, and the sum of the interior angles of a triangle is 180.
Since RT = TU, ∠TRU = ∠TUR = z
114 + z + z = 180
114 + 2z = 180
2z = 180 - 114
2z = 66
z = 66/2
z = 33
Line STU is a straight line and the angle of a straight line is 180. Thus:
114 + ∠STR = 180
∠STR = 180 - 114
∠STR = 66
Also, sides SYT is forms a triangle and the sum of all interior angles of a triangle is 180. Thus:
66 + 31 + ∠SYT = 180
97 + ∠SYT = 180
∠SYT = 180 - 97
∠SYT = 83
But ∠SYT = angle RYV = 83
sides RYV form a triangle and the sum of all interior angles of a triangle is 180
33 + 83 + ∠x = 180
116 + ∠x = 180
∠x = 180 - 116
∠x = 64

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :
$5.89 + $1.45
Taking the whole numbers first:
$5 + $1 = $6
Take the sum of the decimals :
$0.89 + $0.45 = $1.34
Sum initial whole + whole of sum of decimal

A father is 28 years older than his daughter. In six years' time, he will be three times her age. Find their present ages.
Please use an algebraic equation to find the answer and show your working out if possible!!
Answers
Answer:
8 and 36
Step-by-step explanation:
let the daughter's age be x then father is x + 28
In 6 years their ages are
x + 6 and x + 28 + 6 = x + 34
Father is 3 times her age , then equation is
x + 34 = 3(x + 6) ← distribute
x + 34 = 3x + 18 ( subtract x from both sides )
34 = 2x + 18 ( subtract 18 from both sides )
16 = 2x ( divide both sides by 2 )
8 = x
Daughter's age is 8 and father's age is 8 + 28 = 36
A team can spend no more than $300 on shirts. The team has already spent $80. How many shirts for $15 each can they still buy?
Answers
Answer:
80 + 15x ≤ 300
Step-by-step explanation:
max amount = $300
already spent = $80
$300 - 80 = $220
shirts = $15 each
80 + 15x ≤ 300
$80 that is already spent + $15x ≤ $300 maximum
x = number of shirts
