Answer:
B
Step-by-step explanation:
Start by breaking down the equation
-1/2 x 10 = -5
-1/2x1/4=-1/4
Then combine your answer
-5=1/8
Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1
Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
Answer:
Step-by-step explanation:
Distance traveled by Talia = x
Cost for travelling 'x' miles = x * 0.20 = 0.2x
Daily budget = $94
Inequality,
30 + 0.2x ≤ 94
Solution:
0.2x ≤ 94 - 30
0.2x ≤ 64 {Divide both sides by 0.2
x ≤ 64/0.2
x ≤ 320
<span>70 thousand is written in short word form, because its written as a combination of numbers and letters.
Standard form would be to write the number easily using multiplication with 10. That woul be:
70000=7*10^4. It;s 10^4 because the decimal point has been 4 laces to the left to get the number to be 7.
Word form can be obtain by writing the number using letters. Long word form is: seventy thousand. But because sevety is written with number (70), this is short word form of the number,</span>
