For problem 1, it will be 25/100, which is equal to 25%
2) The relationship is that both, the bar model and the proportion, show that x is 1/4 of the actual amount. The bar graph is more a visual. However, in both cases, the x can be solved for to be 25%
3) The percent error for 23°C will be less since it is closer to 25°C, the actual amount. The percent error is greater for 5°C since it is farther for 25°C.
Answer:
Step-by-step explanation:
Given
Required
Determine the x intercept
To get the value of x intercept; we simply substitute 0 for y;
i.e. y = 0
becomes
Multiply both sides by -1
<em>Hence, the x intercept is 6</em>
Multiply the length and width together:
3 2 6
A = ------ * ------ = --------
5 5 25
None of the given possible answers make any sense. Please ensure that you have copied down this problem exactly as presented.
If the width were 2/5 in and the length 3/5 in, then, using decimal fractions, the area would be
A = 0.4(0.6) = 0.24 in^2, which is miles and miles away from 15 in^2 (for example)
<span>X = 65(7)
X = 455
Marla did 455 sit-ups in a week</span>
Step-by-step explanation + Answer:
x = 1st job
y = 2nd job
x + y = 22......x = 22 - y
7x + 8.25y = 171.50
7(22 - y ) + 8.25y = 171.50
154 - 7y + 8.25y = 171.50
-7y + 8.25y = 171.50 - 154
1.25y = 17.50
y = 17.50 / 1.25
y = 14 <== 14 hrs at the 8.25 per hr job
x + y = 22
x + 14 = 22
x = 22 - 14
x = 8 <=== 8 hrs at the 7 per hr job
