Answer:
IL = 11 cm
Step-by-step explanation:
Using the tangent ratio in right triangle IJL and exact value
tan45° = 1 , then
tan45° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{IL}{IJ}[/tex] = [tex]\frac{IL}{11}[/tex] = 1 , thus
IL = IJ = 11 cm
Answer:
11 cm
Step-by-step explanation:
Since m<IJL = 45 deg, and m<JIL = 90 deg, then m<ILJ is 45 deg.
That makes triangle IJL a 45-45-90 isosceles right triangle with congruent sides IJ and IL.
IL = IJ = 11 cm

LMNO is a parallelogram. If NM = x + 15 and OL = 3x + 5 find the value of x and then find NM and OL.
Answers
Answer:
x = 5 unit
NM = 20 unit
OL = 20 unit
Step-by-step explanation:
Given:
LMNO is parallelogram
NM = x + 15
OL = 3x + 5
Find:
x and NM and OL
So,
NM = OL
x + 15 = 3x + 5
2x = 10
x = 5
So,
NM = x + 15 = 5 + 15 = 20
OL = 3x + 5 =3(5)+5 = 20

Renting roller blades costs a flate fee of $5 plus an additional $2.50 per hour. Write a linear equation that models this.
Answers
Answer:
Linear equation : y = 2.50h + 5
Step-by-step explanation:
Given that:
Fee for renting roller blades = $5
Per hour charges = $2.50
Let,
h be the number of hours roller blades were rented
y be the total amount
Total amount = Per hour charges * Number of hours + Flat fee
y = 2.50h + 5
Hence,
Linear equation : y = 2.50h + 5
The graph represents function 1, and the equation represents function 2:
Function 2
y = 5x + 4
How much more is the rate of change of function 2 than the rate of change of
function 1? (4 points)
Answers
Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.
5 is the answer.

Step-by-step explanation:
Well, first let's look at our trig identities. We can set up a cosine function using the given angle:
[tex]cos (46^{o} ) = \frac{x}{16}[/tex] (adjacent/hypotenuse)
Then, multiplying both sides by 16 gives us:

which then you would get -(8+(3/4+1/2)) which gives you -(8+5/4) because you would convert the 1/2 into 2/4 making it to get 5/4. So then you add the -(8+5/4) which gives you -9 1/4.

Diane buys candy that costs $4 per pound. She will spend more than $20 on candy. What are the possible numbers of pounds she will buy?
Use
P
for the number of pounds Diane will buy.
Write your answer as an inequality solved for p.
Answers
Answer:
12 pounds
Step-by-step explanation:
We know that the candy costs $4 per pound
We also know that he will only spend up to $48
We can represent this as an equation:
4x = 48
Where as x = number of pounds
Solve the equation to find how many pounds he can buy.
4x = 48
Divide both sides by 4
x = 12
This means that Kareem can buy 12 pounds

0.1(0.5m+6)=2
Answers
Answer:
m = 28
Step-by-step explanation:
The given expression is :
0.1(0.5m+6)=2
Step 1.
Use distributive property:
0.1(0.5m) +0.1(6) = 2
0.05 m+ 0.6 = 2
Step 2.
Subtract 0.6 both sides
0.05 m+ 0.6 -0.6= 2 -0.6
0.05 m = 1.4
or
0.5 m = 14
Step 3.
Divide both sides by 0.5
[tex]m=\dfrac{14}{0.5}\\\\m= 28[/tex]
Gabi's third step is not correct. It should be m = 28 instead of m = 7.

The Mean Value of a Data Set
The mean or average of a data set is found by adding all numbers and then dividing by the number of values in the set. Written as a formula:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
Where xi is the value of each data and n is the total number of values.
We are given the average weight of n=5 marathon runners:
[tex]\bar x=92[/tex]
Multiplying the formula by n and expanding the sum:
[tex]n\bar x=\sum x_i=x_1+x_2+x_3+x_4+x_5[/tex]
We are given the weighs of four of the runners:
[tex]5*92=89+95+90+90+x_5[/tex]
[tex]460=364+x_5[/tex]
Solving for x5:
[tex]x_5 = 460-364=96[/tex]

Find the range for the possible measure of the third side of a triangle given two sides?
4 cm, 6 cm
Range:
Answers
Answer:
The possible range of the measure of the third side is 2 < 3rd side < 10
Step-by-step explanation:
In any triangle:
The sum of the lengths of any two sides must be greater than the length of the 3rd sideThe length of any side must greater than the difference of the lengths of the other two sidesThe difference of the other sides < The side < The sum of the other sidesLet us solve the question
∵ The measures of the two sides of a triangle are 4 cm and 6 cm
∵ The difference between their measures = 6 - 4 = 2 cm
∵ The sum of their measures = 6 + 4 = 10 cm
→ By using the rules above
∴ The measure of the third side is between 2 and 10
∴ 2 < the third side < 10
∴ The possible range of the measure of the third side is 2 < 3rd side < 10

Chase thought that only 23 people Would come to the banquet but 48 people endd up coming what was his percent error
Answers
Answer:
the percent of people that end up coming as error is 12%
Chase made a miscalculation of 52.08% percent.
What is Percentage Error?
The percent error is the distinction between the estimated value and the actual value in relation to the actual value. In other words, the relative error is multiplied by 100 to calculate the percent error.
Given that, Chase anticipated that just 23 people would attend the event; however, 48 individuals showed up.
The general formula for percentage error:
Percentage Error(%e) = ((Estimated Number – Actual Number)/ Actual number) x 100.
Hence,
Percentage error done by chase = (23 - 48) * 100/48
Percentage error done by chase = -52.08%
Therefore, the Percentage error done by chase is 52.08%
