Answer:
y= 35⁰
x = 55⁰
Step-by-step explanation:
total angle of triangle is 180⁰
therefore we can equate:
x + (x-20) + 90 = 180
2x + 70 = 180
x = 55⁰
total of x and y is equal to 90⁰ since it is a right angle;
x + y = 90
x = 55⁰
55⁰ + y = 90
y = 35⁰
Hey there!
Here is your answer:
<u>The proper answer to this question is "40".</u>
Reason:
<u>40/x=100/45</u>
<u>(40/x)*x=(100/45)*x - we multiply both sides of the equation by x</u>
<u>40=2.22222222222*x - we divide both sides of the equation by (2.22222222222) to get x</u>
<u>40/2.22222222222=x </u>
<u>18=x </u>
<u>x=18</u>
<span>45% of 40=18

Answer: (1) 2p: 5q.
(2) 3:10.
(3) 5:6.
Step-by-step explanation:
To find : Ratio
(1) 4p²q : 10pq²

i.e. Simplified ratio of 4p²q : 10pq² is 2p: 5q.
(2) 9 months : 2½ years
1 year = 12 months

Now, 9 months : 2½ years = 
Hence, Simplified ratio of 9 months : 2½ years is 3:10.
(3) 5 m : 600 cm
1 m = 100 cm
So, 5m = 500 cm
Now, 5 m : 600 cm = 
Hence, Simplified ratio of 5 m : 600 cm is 5:6.
Set variables for the quantities we want to find. Let x = number of applesLet y = number of oranges Next, we use these variables to write equations that describes the whole story. Since the total price is $7.75 and each type of fruit has their own price, we can say 0.40x + 0.35y = 7.55 The other equation will represent the total number of fruits bought all together, as Mark mentioned. Once you have those equations, you solve the system using substitution and elimination methods to solve for the variables x and y.
Answer:
1. 4, -2
2. 3, 0
3. 1, -8
4. 0, 5
5. 2, 5
Step-by-step explanation:
the highest raised to power in a term is called degree
eg: -2x^4
here -2 is always 0
but x is 4
so the highest is 4
the number found in the term is called coefficient
eg: -2x^4
here the only number seen is -2
so the only number is -2
this is same for all term
