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.
Move all terms to the left side then set equal to 0. then set each factor equal to 0. k=-1, -5
Answer:
Last one:
The probability of the spinner not landing on A and rolling a prime number is 1/3
Step-by-step explanation:
The probability of the spinner not landing on A: 2/3
Prime outcomes on a dice:
2, 3, 5
The probability of rolling a prime number: 3/6 = 1/2
The probability of the spinner not landing on A and rolling a prime number is:
2/3 × 1/2
1/3
The length of EF in the given triangle is 8.80 m.
Step-by-step explanation:
Step 1:
In the given triangle, the opposite side's length is 16.2 m, the adjacent side's length is x m while the triangle's hypotenuse measures 16.2 m units.
The angle given is 90°, this makes the triangle a right-angled triangle.
So first we calculate the angle of E and use that to find x.
Step 2:
As we have the values of the length of the opposite side and the hypotenuse, we can calculate the sine of the angle to determine the value of the angle of E.


So the angle E of the triangle DEF is 57.087°.
Step 3:
As we have the values of the angle and the hypotenuse, we can calculate the cos of the angle to determine x.


Rounding this off to the nearest hundredth, we get x = 8.80 m.
Answer:
0
Negative
Un-defined
Things you need to know:
Any line parallel to the x axis is 0
any line parallel to the y axis is infinite/un-defined
Any line that is slanted in that way shown in the picture is negative vice versa the other way it is slanted will be positive.
