x=20°.
hope this helps you.
Cost of airplane toy = $4.84
let x be the cost of the toy car
cost of airplane toy is 4 times the cost of toy car; it means
4x = $4.84
x = 4.84 / 4
x = 1.21
Thus, the cost of toy car is $1.21.
Answer:
X1=-4+4i
X2=-4-4i
Step-by-step explanation:
X^2+8x+32=0
Δ=b^2-4ac=8^2-4(32)=-64<0
X1=(-b-i√Δ) /2a=(-8-8i)/2=-4-4i
X2=(-b+i√Δ) /2a=(-8+8i)/2=-4+4i
Answer:
A)5/8
Step-by-step explanation:
- <em>The range of a set of data is the difference between the highest and lowest values in the set. </em>
<u>Given data set:</u>
<u>Rewriting the data set in the same denominator to compare:</u>
<u>As we see the smallest value is 5/8 and the highest value is 10/8, so the difference:</u>
So, the range of the given data set is 5/8
<u>Correct choice is</u>: A)5/8
