Answer:
170.
Step-by-step explanation:
The number of cell phones = 68 * 3/2
= 102.
Total = 102 + 68
= 170 phones.
Using proportions, it is found that there are 170 phones in all at the apartment complex.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The ratio of landline phones to cell phones at an apartment complex is 2 to 3, hence 2/5 of all phones at the complex are landline phones.
There are 68 landline phones in the complex, hence:
2/5n = 68.
n = (68 x 5)/2
n = 170.

Annie is buying new school supplies. She has a budget of $45, and she has already spent $21. She wants to spend the remaining money on notebooks that cost $4 each. What is the greatest number of notebooks, x, Annie can purchase while staying within her budget?
Part A: Write an inequality to represent the situation.
Part B: Solve the inequality. Show all of your work.
Part C: Interpret the solution in terms of the problem.
Answer:
Part A) 45-21 ≥ 4x
Part C) She could buy up to 8 notebooks
Step-by-step explanation:
She already spent $21 so you would need to subtract that from the total budget. The sign would be greater than or equal to since that's the max amount.
45-21 ≥ 34
34≥4x
Divide both sides by 4 to cancel it out. You would get 8.5 but since you can't buy half a notebook it would be 8.

Solved the inequality incorrectly and graphed their solution incorrectly.
Solved the inequality correctly but graphed their solution incorrectly.
Solved the inequality incorrectly but graphed their solution correctly.
Solved the inequality correctly and graphed their solution correctly.
Answer:
solved the solution incorrectly and graphic their solution correctly.
Step-by-step explanation:
this is because if 4x + 1<= -4
the next step will be to subtract 1 from both sides.
BUT if their solution is x<= 2, they objectively graphed it correctly
Step-by-step explanation:
4x+1 < -4
-1 -1

4x < -5

-5/4 is not 2, so both of them are wrong (1 is right choice)
Which of the following is another way to express the equation 13 = -3 + z?
A. 13 = - z - 3
B. 13 = z - 3
C. 13 = - z + 3
D. 13 = z + 3
The other representation of the given equation 13 = -3 + z will be 13 = z - 3 thus option (C) is correct.
What is the equation?More than one variable may be present inside a linear equation.
An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
As per the given equation,
13 = -3 + z
Since, A + B = B + A
Thus, -3 + z can be written as z - 3
So, 13 = z - 3
Hence "The other representation of the given equation 13 = -3 + z will be 13 = z - 3".

The measure of angle JKL in the triangle JKL is 54°.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
From the given figure line segments JM and ML are of equal measure as the line segment KM bisects JL and hence bisects the vertex angle.
Therefore,
2x + 5 = 3x - 6.
2x - 3x = - 6 - 5.
- x = - 11.
x = 11.
Now, m∠JKL = 2m∠JKM = 2m∠LKM.
So, m∠JKL = 2[2(11) + 5]°.
= 2(22 + 5)°.
= 2(27)°.
= 54°.

Answer:120 is the area to the nearest unit
Step-by-step explanation:
1.Lin and her brother each created a scale drawing of their backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Whose drawing is larger?
2.How many times larger is Lin's drawing than her brother's drawing? You are being asked to compare the size of the areas of the drawings.
Answer:Part 1) The scale for the drawings without units are 1/12 and 1/36
Part 2) The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36. The explanation in the procedure
Step-by-step explanation:we know that
1) Lin used a scale of
Remember that
1 ft=12 in
substitute in the scale
That means ----> 1 unit in the drawing represent 12 units in the actual
2) Her brother used a scale of
Remember that
1 yd=36 in
substitute in the scale
That means ----> 1 unit in the drawing represent 36 units in the actual
therefore
The scale for the drawings without units are 1/12 and 1/36
Part 2) Whose drawing is larger?
The scale drawing 1/12 is larger than the scale drawing of 1/36
To find out how many times as large is the scale 1/12 than the scale of 1/36
Divide 1/12 by 1/36
The scale drawing 1/12 is 3 times larger than the scale drawing of 1/36
Explanation
Let supposing that we want to represent in the drawing a measure that in its real size measures 36 units.
In the scale of 1/12, the drawing will show a measure of 3 units (remember 3(12)=36 units).
At the 1/36 scale, the drawing will show a measurement of 1 unit (remember 1(36)=36 units).
Therefore the largest drawing will be with a scale of 1/12.

HELPPP! ALMOST DUE! Clara estimated that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s actual height is 4 feet, 2 inches. What was the percent error for Clare’s estiamate? PLZ HELP!!!
Answer:
Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%
Answer:
A 4% difference
Step-by-step explanation:
Convert 4 feet 2 into 4.16666666
4/4.16666666= 0.96 or 96%
4 feet was 96% of 4 feet 2 in
100 - 96= 4%
And this shows that there was a 4% error.
