When you add all of these angles, the sum should be 180°. This helps us to figure out the value of the variable.
Now, you must create an equation.
3z+14+z+90=180
4z+14+90=180
4z+104=180
4z+104-104=180-104
4z=76
z=19
∴The value of the variable is 19.
To check:
3(19)+14+19+90
57+14+19+90
90+90
180
All of the angles together have a sum of 180 degrees, meaning that our value for the variable is indeed correct.
Hope this helps.
Answer:
z = 19
Step-by-step explanation:
These are complementary angles; both angles add up to 90°.
To solve this, we can combine like terms.
3z + (1)z + 14 = 90
3z + (1)z = 4z
**3z and z are the only pair of like terms.**
After combining like terms, we can proceed to solve this problem.
4z + 14 = 90.
Since there is an addition sign in front of 14, we do the opposite, subtraction.
First, subtract 14 from 90 and 14.
4z + 14 = 90
- 14 - 14
------------------
4z = 76
**ELIMINATE 14.**
Lastly, divide 76 from 4; this is because 4 is the coefficient.
4x = 76
76 ÷ 4 = 19
Therefore, z = 19.

Based on signal strength, a person knows their lost phone is exactly 47 feet from the nearest cell tower. The person is currently standing 23 feet from the same cell tower. What is the closest the phone could be to the person?
Answers
=========================================================
Explanation:
It might help to draw out a diagram. Refer to the image below. Point A is the cell tower location. Point B is where the person is located. This is a birds eye view. Point B is on the smaller circle of radius 23 ft. The cellphone, which has unknown location, is somewhere on the larger circle of radius 47 ft.
The best case scenario is that the phone is on ray AB, which would make the phone to be 47-23 = 24 ft away from the person. This is the closest the phone could be.
------------------
Extra info:
On the flip side, the worst case scenario is that the phone is on the diametrically opposite side. This would mean the distance from the phone to the person is 47+23 = 70 ft. So the range of possible distances d is [tex]24 \le d \le 70[/tex]

Answers
Answer:
C)All integers are whole numbers.Step-by-step explanation:
A)whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)
integers are the numbers -∞ to +∞ (not including fraction, decimal numbers i.e -5.57, 7.74 etc)
since integers are the numbers including whole numbers thus the statement is true
B)Natural numbers are the numbers 1 to +∞ (not including fraction, decimal numbers i.e 6.89 etc)whereas whole numbers are the numbers 0 to +∞ (not including fraction, numbers i.e 6.89 etc)
hence, the statement is true
C)All Whole numbers are integers but not all integers are whole numbers
therefore, the statement is not true
D)the given definition is the perfect definition of rational numbers
hence, the statement is true

The total number of marbles Janae, Jerome and Gwen have is m + m + 4(m + 2).
m + m + 4(m + 2)
= 2m + 4m + 8
= 6m + 8
The problem says that the total number of marbles Janae, Jerome and Gwen have is less than the number of marbles John has, so that means 6m + 8 is less than 8m + 4
6m + 8 < 8m + 4.
(6m + 8) - 4 < (8m + 4) - 4
6m + 4 < 8m
4 < 8m - 6m
4 < 2m

Find the area of the figure. Round your answer to the nearest hundredth
Answers
Answer:
28.57 in²
Step-by-step explanation:
Okay, so the hearts tops area can be figured out with a regular circle area calculation.
A = π r² =
3.14 × 2 × 2=
6.28 × 2 ≈
12.566in ² .
So we could divided by two, but since the two half circles (the top of the hearts) are of the same size, we don't have to. So now we only have to figure out the area for the square. The radius shows us that one side of the square is equal to 4 in. So 4² or 4 × 4 = 16 in².
No all we do is add the areas: 12.566 + 16 = 28.566 in²
Now to round it: 28.566 in² ≈ 28.57 in²
