Well since we’re given 2 angles, 62 and 58, we have enough information to solve the problem.
Since any triangles angles always add up to 180 degrees, we can simply add up 62 and 58 then subtract from 180.
62
+58
———
120
Now to find the last angle of the triangle you have to subtract 120 from 180 which is 60 degrees. This means x = 60.
However we’re not done, with this 60 we can now calculate y. Since the line is a 180 angle line! We can just subtract 60 from 180 which gives us 120.
The angle of y is 120
Answer:
1/4 ; $28.25
Step-by-step explanation:
Given the following :
Cost of stationeries:
Pencil:$1.20
Eraser:$1
Ruler:$0.50
Total : $169.50
Let total Stationeries purchased = t
Fraction of pencils = 1/3t
Remainder = t - 1/3 = 2/3t
Fraction of eraser = 5/8 of remainder
Thus ;
Fraction of eraser = 5/8 * (2/3)t= 10/24 = (5/12)t
Rest were ruler ;
(2/3)t - (5/12)t= (8 - 5)/12
= 3 / 12 = 1/4t
Fraction of rulers = 1/4
Amount spent on erasers:
(5/12) of the total cost of stationery
(5/12) * 169.50 = $70.625
B.) How much more did she spend on erasers than rulers
Amount spent on rulers :
(1/4) * $169.50 = $42.375
Take the difference :
$(70.625 - 42.375) = $28.25
3(n+5) < 3/4(n)
The three is multiplied by n+5. Whenever you see "is equal to/greater/less than," that is where you put your =, >, or < signs. Your variable, "n" represents the number. So three-fourths of the number is the same as multiplying the number by three-fourths.
Answer:
Step-by-step explanation:
A function is odd if and only if f(-x) = - f(x) and is symmetric with respect to the origin.
The sine function is odd and cosine is even.
Correct option is D
Answer:
9000
Step-by-step explanation:
SI=PRT/100
P=SI 100/RT
=[ 1800×100]÷ 20
= 180000÷20
= 9000
